NOTES ON FLEAS COLLECTED IN THE PROVINCES OF NOORD-BRABANT AND LIMBURG, THE NETHERLANDS (SIPHONAPTERA)

BY

AGNRININGENASSENSEM Se E.RES Department of Zoology, University College, Cork, Ireland

ABSTRACT

Twenty three species (954 specimens) of mammal fleas and two species (12 specimens) of bird fleas were taken from 19 species (336 specimens, 174 infested) of mammals. Nine species (2997 specimens) of bird fleas and five species (13 specimens) of mammal fleas were reared from 204 nests (77 infested) of 45 species of birds. All material was collected in the provinces of Noord-Brabant and Limburg, The Netherlands, in 1964.

Fifteen mammal fleas and five bird fleas were found to be new to Noord-Brabant and two mammal fleas and four bird fleas were new to Limburg. Thirteen species of birds and two mammals were added to Smir's list of hosts for Dutch fleas (SMIT, F. G. A. M, 1962. “Catalogus der Nederlandse Siphonaptera”. Tijdschr. Ent. 105: 45—96, fig. 1-8). New flea-host-associations were ound for 25 flea hosts recorded by SMIT.

The ecology, host and nest specificity, sex ratios and economic importance of fleas are discussed.

Mammal fleas and bird fleas are dealt with separately under their relevant hosts or their nests.

In a synopsis the geographical distribution of all fleas recorded from The Netherlands so far is indicated.

INTRODUCTION

In this paper, which is meant primarily as a report on Siphonaptera collected from mammals and birds’ nests taken in the provinces of Noord-Brabant and Limburg, The Netherlands, some obiter dicta will also be devoted to host and nest specificity, ecology, sex ratios and economic importance of the fleas recorded, while a synopsis of Dutch fleas and their distribution over provinces will be incorporated in the text.

SMIT (1962a) enumerated 50 species and subspecies of fleas recorded from The Netherlands. Of these 39 are mammal parasites and the remainder have avian hosts. These figures compare well with those for the British Isles whence 16 bird fleas and 40 mammal fleas have been recorded (SMIT, 1957b) and with those known from Denmark where of 53 species and subspecies of fleas recorded by SMIT (1954), 13 are parasitic on birds. The bird flea fauna of Ireland consists of 13 species and subspecies of bird fleas and only 22 mammal fleas (CLAASSENS & O'ROURKE, 1965).

The number of bird fleas occurring in mentioned countries is high as compared with a total of about 100 bird fleas known to occur in the world while the total of described species and subspecies of fleas amounts to nearly 1800.

N

TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

The difference in the number of bird fleas in the four countries may be due partly to insufficient study, but must also be accounted for by the difference in ecological requirements of some host specific fleas. The species Ornithopsylla laetitiae Rothschild, occurring on Manx shearwater, Procellaria puffinus puffinus Brünnich, and the puffin, Fratercula arctica grabae (Brehm), has so far only been recorded from the isles west of the coast of England and Wales, and off the coast of Ireland (SMIT, 1957b). The house-martin fleas, Frontopsylla (Orfrontia) laeta (Jordan & Rothschild) and Callopsylla (Orneacus) waterstoni (Jordan), have been recorded only from nests of cliff building house-martins, Delichon urbica (Linnaeus), in Scotland (ALLAN, 1950; SMIT, 1952), and in Ireland (CLAASSENS, 1965a and 1965b). They are further known from Switzerland and the Caucasus (SMIT, 1957a), where they have a very limited recorded distribution.

The relatively poor representation of mammal fleas in these countries is due to the scarcity of mammalian host species. The bird fauna in the same countries is much richer and hence bird fleas have access to a great diversity of hosts and nesting sites, two ecological requirements necessary for different species of fleas to thrive under the given climatic and geological conditions. Phylogenetically, bird fleas are derived from mammal fleas and this secondary evolution together with the wide distribution of many birds may be responsible for the catholic tendencies among bird fleas as regards their adaptive radiation, host specificity and geogra- phical distribution.

Although bird fleas show a lesser degree of monoxenous parasitism than mam- mal fleas, some are restricted to definite hosts or their nests, but it is difficult to determine, in most cases, whether the nest, or the host in providing the nest, lies at the root of this predilection.

Until 1962 only four bird fleas and eight mammal fleas were recorded from Noord-Brabant (SMIT, 1962a). The fleas of Limburg were fairly well known by that time, especially the bat fleas for the study of which the southern part of this province offers a unique opportunity. Moreover, this part of the country has many geological, floral and faunal peculiarities all of which of necessity lure naturalists of all kind to visit it and discover its secrets.

From the many mammals and birds’ nests collected mainly during the months of October, November and December, 1964, the author recovered 23 species of mammal fleas and nine species of bird fleas. Records of 15 mammalian and five bird fleas were found to be new to Noord-Brabant and two of the former and four of the latter were new to Limburg. In the following synopsis of the recorded Dutch fleas all provinces from which a species was reported are given, while the provinces from which new records were made by the author, are marked with an asteric. The abbreviations used for the provinces and islands are as follows: G. = Groningen; F. — Friesland; D. — Drente; O. — Overijsel; Gld. — Gelderland; U. — Utrecht; NH. = Noord-Holland; ZH. = Zuid-Holland; Z. = Zeeland; NB. = Noord-Brabant; L. — Limburg; T. = Texel; V. = Vlieland; Ts. = Terschelling; A. = Ameland; S. — Schiermonnikoog; R. — Rottum.

For the exact geographic position of the localities within the provinces from where fleas were recorded, see SMIT (1962a) on whose paper this synopsis is based and whose classification and nomenclature of Siphonaptera are used. The

MATERIAL AND METHODS

Trapping of mice, voles and shrews was done with eight live traps constructed of wire netting which, though very efficient for catching small mammals proved less dependable as regards keeping the animals alive. All traps were baited with cheese and checked every morning from October 4th until December 15th, 1964. Six traps made of wood were used in our house and garden. These were also baited with cheese and checked at regular intervals every day from June 15th until December 15th, 1964. All animals trapped in and near our house were collected alive. Three pygmy shrews, Sorex minutus Linnaeus, and one common shrew, Sorex araneus Linnaeus, were captured in jars used as pitfalls at Konings- hoeven, Tilburg.

All catches dead or live were put in separate polythene bags and, if necessary, killed from the outside before they were searched for fleas. Five or six white- toothed shrews, Crucidura russula (Hermann), caught in our garden at Tilburg were anaesthetized with ether before ectoparasites were removed from them. They were marked at the ears and released to be recaptured.

Rats were killed in and near farms and farm out-houses. Moles were collected in gardens and meadows. Squirrels, polecats, weasels and stoats were examined in a taxidermist’s workshop at Oisterwijk. The taxidermist put all incoming animals in polythene bags and stored them in a deepfreeze until they were examined by the author. Three squirrels were shot by the author on the estate Villa Blanca, Goirle. These squirrels appeared to harbour the largest number of fleas per individual host in the present investigation.

Some mammal fleas were also collected from birds’ nests while some bird fleas were recovered from the bodies of mammals especially of animals of prey.

Each animal was carefully searched for fleas and other ectoparasites by putting the contents of each bag into a deep white bowl and by brushing and blowing against the grain of the fur to remove parasites that had stayed on the dead hosts.

Bird fleas were collected from nests taken in the field. Only those nests of which the origin was certain were kept for incubation. Several bird watchers and foresters were of great help by showing nests of birds known to them.

The nests were put in separate polythene bags and kept at room temperature (18° C) for seven days. They were then carefully searched for fleas. The author is well aware of the fact that the nest material should have been kept for a longer period in order to obtain the maximum number of parasites that could possibly be bred from the pupae and maybe the larvae present. The shorter method was followed because of lack of time and space.

Often fleas were seen moving up the inside walls of the bags within a day or two. This happened always when a nest harboured many fleas. In such cases the contents of the bags were searched earlier, preferably daily, in order to prevent loss of fleas by drowning in the moisture accumulating on the inside walls of the bags. Sometimes fleas were seen in the nesting material directly after col- lection but usually they were not seen before incubation.

Fleas were picked up with a Leonhard forceps and stored in 70% alcohol until they were prepared for identification. The techniques used to mount the fleas

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg 7

were those described by Smit (1957a) whose keys were also used for identification of the insects (SMIT, 1954, 1957a, 1962a). For nomenclature of the mammals and the birds we followed BRINK (1955), and DOBBEN (1963), respectively.

RESULTS AND DISCUSSION

A. MAMMALS

In the discussion under every mammal or group of mammals some incidental remarks will be devoted to ecology and host specificity of the fleas occurring on them. The reader is advised also to read SMIT (1962a) who gave a detailed account of every species of flea and a complete synopsis of “Host-flea-associations” recorded from The Netherlands until 1962.

Trapping of shrews was described in “Material and methods”. All shrews caught in this way were found dead in the traps except for six shrews recorded from our garden at Tilburg. Pygmy shrews were trapped in pitfalls, which were not baited and in which the shrews were found dead. Of all fleas collected from the Sorici- dae examined, 55% were D. d. dasycnema and 26% P. s. soricis.

Palaeopsylla soricis soricis and Doratopsylla dasycnema dasycnema are host specific parasites of shrews. The latter species is a nest parasite and according to SMIT (1962a) this may be one of the reasons why the species has not been collected much in the past. Moreover, shrews tend to harbour few fleas per individual host. Of the two specimens of S. araneus recorded from Mill the female carried seven specimens of D. d. dasycnema, an infestation worth recording. Remarkable is also that on the bodies of the hosts male specimens of this flea are more abundant than females. SMIT (19622) commented that the sex ratio is nearly

8 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

2:1 in favour of the males. Our figures agree very well with SMIT's obser- vations.

Although P. s. soricis is a body flea rather than a nest dweller, we found few specimens of this species on the hosts examined.

C. b. heselhausi is a host specific mole flea and is particularly found in moles’ nests. Shrews are recorded as accidental hosts for this flea as well as for the rat flea, N. fasciatus. Shrews are secondary hosts for the flea H. t. talpae. N. fasciatus has not been recorded before from shrews in The Netherlands, but SMIT (1957b) recorded it from S. araneus in the British Isles. SMIT (1962a) lists ten species of fleas found in association with shrews.

Crocidura russula was collected from live traps set out in three different locali- ties. Unfortunately the specimens from our garden harboured only one N. fasciatus and no other species of fleas. Five of the six white-toothed shrews from the garden were marked and released. These were all recaptured sometimes twice a day for about a week. After that time they seemed to have disappeared from our garden where they had suddenly turned up. We had hoped to see whether C. russula, which occupied the same shelter places as Mus musculus, was liable to become infested with Leptopsylla segnis, the house-mouse flea, or possibly with other fleas that might have straggled into our garden on passing mammals. Al- though many house-mice were trapped, few were found infested and straggling onto C. russula did not occur, at least not during the short time we were able to recapture them.

All fleas, except H. t. talpae, recorded from C. russula examined by us are new host records.

Sorex minutus has not been recorded before as a host for fleas in this country and hence all species of fleas reported from them at Tilburg are new records. Our attempts to catch water shrews, Neomys fodzens Pennant, near ditches and ponds failed, nor did we succeed in trapping the bicolour white-toothed shrew, Crucidura leucodon (Hermann), which may occur in Noord-Brabant. No fleas have so far been recorded from C. /excodon in The Netherlands.

SMIT (1962a) lists two host specific mole fleas, four secondary and nine accidental ‘‘flea-mole-associations’’. Of all fleas collected from moles by us, 62% belonged to the species P. minor. C. a. smitianus and H. t. talpae are often

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg 9

found on moles, but they constitute only a secondary host-relationship. M. turbidus being a host specific vole flea must be regarded as a straggler when occurring on moles. P. s. soricis, a host specific shrew flea may also straggle onto moles. C. b. heselhausi, the second specific mole flea is a nest dweller and this may explain why it was not found by us. The host specificity of P. minor and C. b. heselhausi was wel demonstrated by SMIT (1962b), who found that of the 13,330 fleas col- lected from 1,005 moles and 45 moles’ nests at Wilp, Gelderland, The Netherlands, during a period of eleven years 90% of all fleas recovered from the moles and only 4.6% of all specimens retrieved from the nests were P. minor while 65.5% of all fleas taken from the nests and only 2.4% of all fleas gathered from the hosts were C. b. heselhausi. In Noord-Brabant C. b. heselhausi was recorded from Breda, where it was found in a mole’s nest (SMIT, 1962a). We record it from S. araneus at Tilburg.

A. sylvaticus is a very common mammal in The Netherlands where it inhabits nearly all terrestrial biotopes. It is the mammal par excellence for the study of fleas of small mammals occurring in an area because it attracts the great majority of species of mammal fleas, even those of which other small mammals are the principal hosts. The author found it possible to predict what species of mammals could be expected in a given area after examining a small number of flea-infested field mice. It was also found that mammals other than field mice were caught only after part of the population of the latter occurring around the spot where traps were set out had been trapped. This was also true for the bank vole, Clethrionomys glareolus, which as a rule enters traps before A. sylvaticus, whenever these two species share a habitat. C. glareolus is to some extent also a diurnal mammal and may therefore seem to be easier caught than A. sylvaticus. The common shrew, Sorex aranens, was never trapped before field mice and bank voles were captured. Although mice, voles and shrews live in close proximity, they seem to avoid each other in the open. It is therefore a good practice to leave traps for three or four consecutive days on the same spot rather than to keep moving them from one place to another after every night.

Many species of fleas have been found in association with field mice. Most of these relationships are of a secondary or accidental nature. Typhloceras poppei and

10 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

Ctenophthalmus agyrtes subspecies are regarded as the principal Siphonaptera found in association with this mammal. Megabothris turbidus appeared to be fairly com- mon on the mice examined, but SMIT (1962a) regards A. sylvaticus as an ac- cidental host for this flea, which has the bank vole, C. glareolus, for its principal host. Three specimens, two males and one female, of the subspecies H. t. talpae were found on a female field mouse caught on the estate Villa Blanca, Goirle. This mouse also carried one specimen of the subspecies C. a. smitianus. The record of the Apodemus—H. 1. talpae association is new to The Netherlands (see discussion under C. glareolus). The occurrence of Palaeopsylla minor, a mole flea, on Apodemus is also a new host record. N. fasciatus, the rat flea, may often be found on small mammals whenever they share the same territory with rats so that exchange of fleas and other ectoparasites can easily be accomplished.

The bird flea Ceratophyllus g. gallinae was found on several mammals during our survey. This flea will feed on mammals when hungry, but its association with mammalian hosts must be regarded as accidental.

Special attention was paid as to whether the beetle Leptinus testaceus Müller (Col., Silphidae) occurred on A. sylvaticus or on any other small mammal or in birds’ nests in Noord-Brabant and Limburg, but no specimen was found. The beetle was frequently found on field mice in Ireland (FAIRLEY, 1963b; CLAASSENS & O’ROURKE, 1964) and in Great Britain (J. BALFOUR BROWNE, British Museum, Natural History, personal communication). FAIRLY (1963b) reported that 15% of male and 4% of female Apodemus (138 specimens) taken in Co Down, Ire- land, in October and November, 1962, harboured this beetle. We examined 109 field mice in Co Cork, Ireland, and found 12% of the males and 13% of the females infested with this beetle (CLAASSENS, 1964). KEER (1930) reported this beetle from The Netherlands as occurring on field voles, Microtus arvalis, on rats and long-tailed field mice. SMIT (personal communication) found it on A. sylvaticus in various parts of The Netherlands.

The beetle, which has also been recorded from nests of A. sylvaticus (O’MA- HONY, 1945, 1947), from birds’ nests (RYE, 1890; JOHNSON & HALBERT, 1902; LINSSEN, 1959; and CLAASSENS, 1964) and from the nests of Bombus terrestris (CuMBER, 1949), may also be found in rotten wood (LINSSEN, 1959) and in dead leaves (RYE, 1890). L. testaceus can be recognized by the long filiform antennae, and the absence of eyes. It is oval, small, 2 mm, very flattened, and dull testaceous in colour. It is still a matter of speculation as to whether the beetle has a parasitic, nidicolous or phoretic association with A. sylvaticus.

Although the black rat, Rattus rattus (Linnaeus), and the brown rat, R. norvegt-

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg 11

cus, occur in Noord-Brabant and Limburg, only the brown rat of more frequent occurrence was obtained during our survey. The abundance of the brown rat may be illustrated by some recent figures. A poultry farmer at Mill killed 407 rats in one day in a hen house (November, 1964); another caught 173 rats in one hen house also in one day (October, 1964) and a farmer at Tilburg killed 77 rats in October, 1964, also in a hen house. Many rats are killed too by poisoned bait; it is impossible to determine how many rats are killed daily by this method.

In addition to the damage they do to property of all kind, rats are vectors of diseases which they may disseminate to domestic animals and even to man. Some of these diseases are transmitted by ectoparasites, most important of which are the fleas.

Our observations revealed a predominance of N. fasciatus infestations on the rats examined. Although N. fasciatus is the common rat flea, it need not always be the predominant species of flea on rats in any area in Europe. CLAASSENS & O’ROURKE (1965) reported that of sixteen rats collected from four counties in Ireland only two carried N. fasciatus exclusively while all others were infested both with N. fasciatus and Ctenophthalmus nobilis (subspecies), or only with C. nobilis (subspecies). Of a total of 54 fleas collected from the 16 rats ten were N. fasciatus and all the other were either C. nobilis nobilis (Rothschild, 1898) or C. n. vulgaris Smit, 1955. Further investigations would be of interest. There may exist an inter- specific competition between the species of the genus Nosopsyllus and those of the genus Ctenophthalmus when these species occur on rats occupying the same area.

Although Smir (1962a) listed nine species of fleas as being reported from brown rats in The Netherlands, we found only four, two of which were single specimens.

For the economic importance of rat fleas see the chapter on domestic and medical importance of fleas in this paper.

Mus musculus Linnaeus, the house mouse. Taken from our garden and house situated just outside the city boundary of Tilburg. Trapping of these mammals was started June 15th, and continued until December 15th, 1964. All mice were col- lected alive from the traps. The greater part (17 of 27 specimens) captured in- doors were killed with a stick because they refused to enter traps. All other mice were caught in live traps baited with cheese. Mice of the outdoor population were grey brown on top and grey underneath while members of the indoor population had back and underside grey. Some of the mice killed indoors during November and December obviously belonged to the outdoor population.

Most of the mice were trapped near a small dump and in an aviary where they appeared to congregate after arriving in the garden. Trapping was started in June, but until September 15th only four mice were captured in the garden and three of these harboured fleas, while of the many mice obtained later very few fleas were recovered. Six shrews were also obtained from near the dump. For shrews see under Soricidae in this paper.

In table I details are given concerning the mice examined and their flea popu- lation. All mice taken during four weeks are put together in order to show the change in population density both of mice and their epi-fauna, as well as to demonstrate that species of fleas other than Leptopsylla segnis were removed only from those mice which visited our garden after August.

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg 13

Of the outdoor population (38 4 and 21 @ ) only 16% of 4 and 19% of 9 were infested with fleas, while of the indoor mice (14 & and 13 9) and 70% and 70%, respectively, were infested. The remarkable difference may be explained by the fact that mice travelling from one place to another lose their ectoparasites. When searching for winter quarters mice may spend only a short time in the same hiding place and fleas which stay on the host only for a limited time to feed, are left behind.

Of the outdoor mice taken in August three of four specimens were infested, but two of these carrying fleas may have belonged to the local population of the garden where a stock of fleas may have been built up in their usual hiding places. The big invasion of mice took place during November, when 41 specimens were trapped. The last mouse was caught in the garden on December 10th. Trapping was continued until January 10th but not a single mouse could be trapped. Yet mice were sometimes seen during day-time. They seemed to have established a definite abode and as a result they might have regained their timidity and shyness. One female mouse was caught in the house on December 22nd, but it harboured no fleas.

The great predominance in the outdoor population of males over females is worth noticing. It would be of considerable interest to repeat such studies preferably during a longer period and with the aid of more traps.

It is the right place here to express sincere thanks to Messrs. H. VAN DER ZANDE and H. SOETENS who were of indispensable help in catching the specimens of Mus musculus.

Though less common in some areas than the long-tailed field mouse, the bank vole is widely spread throughout The Netherlands. It avoids wet places and has a preference for deciduous woodlands, hedges, shrubs, edges of woods and may also occur in coniferous forests.

Ctenophthalmus agyrtes subspecies, C. congener congener, Peromyscopsylla sil- vatica and Megabothris turbidus are the principal fleas of C. glareolus in this coun- try. With the exception of the subspecies C. agyrtes all these Siphonaptera were recovered from the bank voles examined. According to SMIT (1962a), C. glareolus

14 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

is a secondary host for C. a. smitianus, but it was by far the most common species on the bank voles examined by us. For the geographical distribution of C. a. agyrtes and C. a. smitianus in The Netherlands see the synopsis of Dutch fleas in this paper and also SMIT (1962a).

H. t. talpae is a nest flea but it has been also found regularly on the bodies of mice, voles, moles and shrews. It is difficult therefore to determine the principal host of this largest of the European fleas. In Ireland H. #. talpae was often found on A. sylvaticus (FAIRLEY, 1963a; CLAASSENS & O'ROURKE, 1965). Moles are ab- sent from Ireland and 18 voles, C. glareolus, examined there were not infested with this flea. For the discovery of the bank vole in Ireland see CLAASSENS & O'GORMAN (1965). The occurence of N. fasciatus on the bank vole is accidental, while the common bird flea, Ceratophyllus g. gallinae, is merely a straggler.

Rhadinopsylla pentacantha is usually found in association with A. sylvaticus. Its occurrence on C. glareolus is a new host record for The Netherlands. The record of P. silvatica is the second for The Netherlands. We took it also from a weasel, Mustela nivalis, shot at Oisterwijk. This Leptopsyllid mammal flea had been recorded before from Oldebroek (Gld.) where it was found on C. glareolus (SMIT, 1962a). SMIT commented that P. silvatica is not a very common parasite of voles but it has a wide distribution in Europe and a closely related subspecies, P. silvatica spectabilis (Rothschild, 1898) occurs in Great Britain and Spain.

Few fleas from the common vole, M. arvalis, have so far been examined. Spe- cial attempts were therefore made to catch these mammals. Although only four species of fleas on voles were found, the general trend of their flea infestation was well shown.

C. assimilis was the flea most commonly found on the 13 voles infested (59% of all fleas collected from them). C. assimilis is a host specific flea of the com- mon vole (SMIT, 1962a). It appears to be a nest flea and is not often found in big numbers on the bodies of the hosts.

The carnivores listed above are not usually infested with fleas. They acquire these parasites by preying upon small mammals and birds. SMIT (1962a) lists several species of fleas recorded from these mammals, but the records of C. a. smitianus, P. silvatica and the bird fleas, C. garei and C. g. gallinae, are new to The Netherlands. Minks were never recorded before as accidental hosts for Si- phonaptera in this country. We have investigated only some nests of these mam- mals when nest boxes were taken out of the cages on a mink farm. The mink farm was situated in a forest and fleas from the long-tailed field mouse or from the common shrew may have straggled onto these unusual hosts and from them into the nesting material.

C. a. smitianus was found most often on the carnivores examined. This is of course not surprising since many small mammals harbour this flea. Squirrel fleas were found on pole cats and stoats, but this is not unusual either, because squirrels abound in all areas where Mustelidae were captured.

The red squirrel, Sciurus vulgaris, is very common in most wooded areas in The Netherlands. Many specimens are shot every year in an attempt to keep their numbers in check and to decrease the damage done to the forests and bird fauna. Lack of natural predators, especially martens and wild cats made interference of man necessary. It is of interest to recall the records of the squirrel flea, Monopsyllus sciurorum, from the pole cat and stoat. These Mustelidae as well as the weasel appear to prey upon squirrels, but they seem to have little effect on the squirrel population.

M. s. sciurorum is the most common host specific squirrel flea in this country,

16 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

both on the bodies of the hosts and in their nests. This flea is often found in cons- iderable numbers on squirrels and is said to be even more numerous in some nests. One of the squirrels shot on the estate Villa Blanca, Goirle, harboured 30 females and 24 males of this flea. Tarsopsylla o. octodecimdentata, another host specific squirrel flea, has been found in the provinces of Overijsel and Gelderland. It is a nest flea and is never found in large numbers on the host. SMIT (1962a) com- menting on this flea noted that it is more frequently found in association with squirrels occupying territories in mountainous areas.

Of the squirrels’ nests the two collected at Beers were newly built. The grass covering the inner lining of hay was still partly green. Though the number of fleas found in these nests was small, they provide an indication that transport of fleas from the bodies of the hosts to their nests occurs rapidly. The nests collected at Beers were so-called “winter nests”.

The fleas C. g. gallinae and C. garei may have straggled onto squirrels from deserted birds’ nests which are often visited by squirrels and may occasionally be used to store their food. No bird fleas were found in the squirrels’ nests examined. The bird flea-squirrel-association must be very short-lived.

CHIROPTERA

SMIT (1962a) enumerated 11 species of bat fleas recorded from 13 species of bats. No bat flea was hitherto recorded from Noord-Brabant; from Limburg on the contrary nine bat fleas have been recorded in the past and nearly all were recovered from bats occupying the caves of South Limburg. Nycteridopsylla eusarca Dampf, 1908, and Ischnopsyllus elongatus (Curtis, 1832) are species of bat fleas not yet reported to occur in Limburg. Both the latter species are host specific parasites of the bat Nyctalus noctula (Schreber) which does not hibernate in caves.

In Noord-Brabant we found one male Ischnopsyllus elongatus on a female Ep- tesicus serotinus (Schreber) taken at Vught from a crevice in a wall, December, 1964; a female Ischnopsyllus octactenus (Kolenati) on a female Pipistrellus pipi- strellus (Schreber) taken at Vught from a hole in a tree, December, 1964; one female Ischnopsyllus hexactenus (Kolenati) from the nest of a stock dove Columba oenas Linnaeus, which was situated in a hole in a wall under the eave of a house and one female of the same species from a female Plecotus auritus (Linnaeus) ta- ken from a cellar, both records from Mill, December, 1964. Seven Plecotus auritis 5 4,2 9) were taken from a farmhouse at Tilburg. These bats were not infested with fleas, nor could any fleas be bred from the debris gathered from under the roost.

Although bats have no nests, they have specific fleas; this can be explained by the fact that bats return to a definite roosting place to rest, sleep or hibernate. This habit, which provides conditions not unlike those in a bird’s nest, suits the adult fleas, while the faeces of the bats, accumulating on the floor under the roots, ensure ideal food, shelter, temperature and humidity for the larvae of fleas and other ectoparasites.

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg iy

DOMESTIC INFESTATIONS

Man and domestic animals can act as hosts for several species of fleas, which if conditions are suitable may become annoying pests.

Fleas usually responsible for domestic infestations are Pulex irritans Linnaeus, the so-called human flea; Crenocephalides canis (Curtis), the dog flea, and Cteno- cephalides felis felis (Bouché), the cat flea. These species and subspecies were taken by the author on a farm at Oisterwijk, November, 1964, where a dog har- boured 1 © of P. irritans and 1 3, 1'9 of C. canis, two cats carried 2 & of P. irritans and 1 8,2 9 of C. felis felis and 1 9 of C. canis, and five specimens (3 4, 2:2) of P. irritans were collected from two pigs in December, 1964.

Another species of domestic importance is, as we have seen already, Nosopsyllus fasciatus, the rat flea. Of less domestic importance are the species Leptopsylla segnis (Schönherr), Archaeopsylla e. erinacei (Bouché) and Spilopsyllus cuniculi (Dale) and the bird fleas Ceratophyllus g. gallinae (Schrank).

There are not many recent records of rat flea infestations in houses. SMIT (1962a) recorded a rat flea from a house. We obtained a rat flea from a mouse captured in our kitchen (see under Mus musculus). CLAASSENS & O'ROURKE (1965) re- ported a female N. fasciatus from a bed in a Cork suburb (Ireland).

L. segnis, the house mouse flea, feeds on man only when hungry; it could be contracted in rooms infested with house mice.

A. e. erinacei, the hedgehog flea has been recorded from cats and dogs and via these domestic animals it may be passed on to man. O'ROURKE (1960) commen- ting on animal pets as reservoirs of zoonotic infections, noted that the hedge- hog accumulates and excretes all strains of Leptospira available in an area. It is however, not known, whether fleas are capable of transporting Leptospira from animals to man. We obtained three females and one male of the subspecies A. e. erinacei from a dog which had been playing with a hedgehog (Tilburg, October 15th, 1964). The fleas were put back on the dog, which was re-examined on October 17th. Only one female flea could be found then and though it is not easy to find four fleas on a dog, we assumed that the parasites had left the unusual host. The ob- stinate female persevering in its accidental host relationship was kept for our col- lection. One female was also found on a pole cat and one male and two females were taken from a weasel (see under records of fleas from Mustelidae).

Two male and one female specimens of S. cuniculi were taken from 15 domestic rabbits of which only one was infested (Wanroy, November, 1964). One male was also taken from a rabbit trapped at Mill, November, 1964.

S. cuniculi is a semi-sedentary flea. It attaches usually to the innerside of the ears of rabbits and of accidental hosts such as cats, dogs and hares. Heavily serrated lacinia ensure a firm attachment. S. cunicnli is the principal vector of the Myxoma virus in Western Europe. This virus is transmitted purely mechanically by the in- fected mouth parts of the rabbit flea. Occasionally rabbit fleas may feed on man. Hunters, and people dealing with dead rabbits are most liable to contract these fleas.

Ceratophyllus g. gallinae, a very common bird flea has often been reported to infest hen houses and may occasionally be found on mammals. During our obser-

18 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

vations in Noord-Brabant and Limburg we found it on Apodemus sylvaticus, Mustela putorius and Sciurus vulgaris.

The ability of this flea to maintain itself in dry aerial nests may have guided it to hen coops where the egg-laying and roosting habits of the hens must suit the fleas very much. It has been proven that C. g. gallinae will breed when fed only on rat’s blood. We used white mice to feed hundreds of specimens of this flea. In hen houses C. g. gallinae may become a real pest and may have a deleterious effect on the health and egg production of the fowl. Where hens, dogs and cats live in close proximity one will often find fleas straggling from fowl to mammals and via these to man. Man can also contract C. g. gallinae by cleaning infested hen houses.

MEDICAL IMPORTANCE

Fleas are hosts to a variety of organisms, several of which can be harmful to the fleas only while others may also be passed on to the fleas’ hosts. In some cases such organisms may be passed on to man directy or via other hosts. N. fasciatus, P. irritans, C. canis, C. f. felis and L. segnis are potential carriers of the Plague bac- teria, Pasteurella pestis. Some fleas act as intermediate hosts of cestodes of medical importance. The more common cestodes are Hymenolepis nana Siebolt, Hymenole- pis diminuta Rudolphi and Dipylidium caninum Linnaeus. Hymenolepis diminuta is a parasite of rats and mice. Humans, especially children have been found infested too. The intermediate hosts of the tailed cysticercoids are the flour moth Anzsolabis annulipes and the larval and adult forms of some beetles and the flea N. fasczatus. Human infestations are usually accomplished by consumption of fresh faeces of rats and mice (faecal contaminated food) and by consumption of insufficiently cooked bread stuff made from flour infested with grain insects.

H. nana is a parasite of rats and mice and even humans, especially children. Ingestion of ripe eggs of the cestode is possibly the commonest method by which humans, rats and mice become infested. There are a number of intermediate hosts in which the cysticercoid will develop and from them can be transferred to definite hosts. Important intermediate hosts are the fleas C. canis, P. irritans and some mealworms.

Dipylidium caninum is a cosmopolitan parasite of cats and dogs and may infest children occasionally. Intermediate hosts are C. canis and P. irritans as well as the dog louse Trichodecta canis. Dogs and cats infest themselves by eating infested fleas or lice. Children may be infested by accidentally eating infected fleas or lice, or cats and dogs may chew up the intermediate hosts and set free cysticercoids on to their coat or retain them in their mouth from where they can easily be passed on to man.

N. fasciatus is the most important vector of Endemic or Murine typhus. This disease is transmitted from rat to rat and other small mammals and from them to man by fleas. C. canis and C. f. felis have also been reported to be naturally infected with this disease and may therefore be potential carriers. L. segnis and possibly other fleas of small mammals are carriers of Murine typhus among their hosts and at times from these to man. The causative agent of Murine typhus is

A. J. M. CLAASSENS : Fleas in Noord-Brabant and Limburg 19

Rikettsia mooseri which multiplies intracellularly in the fleas. Faeces of in- fected fleas are highly infectious. Human infestation is believed to occur when Rikettsia penetrate abraded skin at the sites of flea bites contaminated with flea faeces.

Two other diseases may possibly be transmitted to man by fleas: Tularemia and Salmonellosis. The etiological agent of Tularemia is Pasteurella tularensis. It has many vertebrate reservoirs and arthropod vectors, the most efficient ones being ticks which are often responsible for this disease in man. There is little in the epidemiology of Tularemia in man to suggest that fleas are important vectors. But fleas appear to play a definite part in transmission of Tularemia to animals, and man usually contracts Tularemia by handling infected mammals. Trappers and hunters are particularly liable to become infested. Tularemia is a plague-like disease, mainly affecting rodents in North-America, Japan, U.S.R.R., and several European countries. In man it has a mortality rate of four percent.

Salmonellosis has been transmitted experimentally to mice by the fleas Xenopsylla cheopis (Rothschild) and N. fasciatus. These fleas were infected with Salmonella enteritides and S. typhimurium, but only the former bacterium was transmitted and the exact mode of transmission was not determined. Regurgitation into the bite-wound of the host seemed probable.

For collateral reading on economic (domestic veterinary and medical) impor- tance of fleas we refer to JELLISON (1959), LAPAGE (1956 and 1957) and RIVERS & HORSFALL (1959).

SEX RATIOS IN MAMMAL FLEAS

Significant numbers of specimens of fleas for a reliable determination of their sex ratios were obtained for Crenophthalmus agyrtes smitianus (88 specimens, 50% males), Leptopsylla segnis (79 specimens, 45% males), Monopsyllus s. sciurorum (602 specimens on the bodies of the hosts, 48% males and 63 specimens from three nests, 43% males) and for Nosopsyllus fasciatus (31 specimens, 30% males).

The predominance of females among mammal fleas is usually pronounced. The highest ratio was found for N. fasciatus. CLAASSENS & O'ROURKE (1965) found 30% males among specimens of N. fasciatus collected in Ireland. SMIT (1962b) reported that of 13,330 fleas collected from 1005 moles and 45 moles’ nests the sex ratio for the former was 47% males and for the latter 38% males. Female fleas according to SMIT may spend more time in the nests than males. MEAD-BRIGGS & PAGE (1964) surmised that the predominance of female fleas on the bodies of hosts may be due to the greater need of nutriment for egg production. Since female fleas are more numerous both on the hosts and in their nests it is clear that at any stage in the adult state of fleas females outnumber the males. One exception may be Doratopsylla d. dasycnema, a host specific shrew flea for which the sex ratio for specimens on the bodies of the hosts is about 2 : 1 in favour of the males. See also sex ratios in bird fleas in this paper.

B. BIRD'S NESTS

Nearly 200 birds are known to breed in The Netherlands (SMIT, 1962a), but only 44 of these have so far been recorded as hosts of Siphonaptera. During our survey we found fleas of 13 unrecorded avian hosts’ nests and for 13 other species of birds new host-flea-associations were found.

In the following synopsis of the material collected during the months of Oc- tober, November and December, 1964, the newly recorded hosts and the newly recorded flea-host-associations have been marked with an asterisc. It can be used as a supplement to SMIT (1962a).

The localities from which nests of each species of birds (nests of 45 species of birds were examined) were collected are listed. After each locality the number of nests investigated and the number (in brackets) of nests found infested are given together with the number, sex and species of flea collected after incubation of the nests. The first figure under each species of flea indicates the number of male and the second figure indicates the number of female specimens obtained. All birds are listed under their respective families. For the nomenclature of the birds we have followed DoBBEN (1963). Subspecific names were only used for subspecies easily recognisable in the field.

DISCUSSION OF NESTS INVESTIGATION

A total of nine species of bird fleas and five species of mammal fleas were col- lected from 204 nests of 45 species of birds. Not less than 77 nests (38%) were found to be infested. The number of fleas collected from individual nests was very variable. This of course was partly due to the ecological conditions prevailing in the nests after they were deserted by the birds. There may also be an inter- specific difference in the reproductive capacity of fleas. C. garei and C. g. gallinae, as well as all martin fleas appear to be prolific breeders, while D. g. gallinulae and C. fringillae may have a less abundant offspring. Furthermore the main breeding season of bird fleas coincides with that of the bird hosts and hence the longer a nest is occupied either by adult or young birds the more favourable conditions are for the reproduction of fleas. Although most of the nests collected by us will have been occupied for at least some time by the hosts we have no idea about the duration of this occupation. The dry hot summer and our collecting of nests at random may be responsible for the moderate percentage of nests infested. ASH (1952) examined 109 nests of 23 species of birds in England and found that of 27 nests which had not contained young birds before they were deserted by the adults, 41% were infested; of eight nests which had contained young, but which were deserted by the adults before the young could leave, 50% were in- fested; of 66 nests from which young had fledged 56% were infested, and of eight nests which had contained eggs at one time but in which it was doubtful whether there had been young or not, 40% were infested. These figures show that the duration of occupation of nests by birds influences the degree of infestation.

The main difference in the percentage of infested nests examined by AsH and ourselves is due to the fact that we included 46 nests of tree-nesting birds which on the whole provide poor ecological requirements for ectoparasites to maintain themselves in these nests. Only ten of those 46 nests were found infested. Moreover, ASH collected birds’ nests earlier in the year at a time that fewer fleas (larvae and pupae included) were lost through predation by enemies of fleas and through the activities of internal and external parasites. Taking all circumstances into account the percentage of infestation obtained by us may be considered rather high and it is an indication that by the majority of fleas hibernating is accomplished by survival as adult but especially as pupae in the hosts’ nests. It would be of interest to examine a collection of birds’ nests collected in February and March and compare the results.

Host SPECIFICITY IN BIRD FLEAS

The species C. hirundinis, C. rusticus, C. f. farreni and C. s. styx are monoxe- nous parasites of the family Hirundinidae. C. columbae is a pigeon flea. The degree of humidity in the nests seems to determine whether any of the remaining four species of fleas will thrive or not. Since the situation of the nests is the chief factor determining the humidity one can conveniently divide birds’ nests into the following four categories:

1, nests on or near the ground or otherwise in a wet position;

2, nests of bush nesting birds and nests built in positions providing the same degree of humidity. Nests in coniferous trees especially those in low position would belong to this group;

3, nests of hole nesting birds. The holes may be natural as well as artificial. Nests of sand martins, woodpeckers, tree creepers, as well as nests built in crevices of rocks and walls and those built in nest-boxes constitute this group;

4, nests of tree nesting birds. These nests are usually very dry, at least during the hot summer season. Many of these nests will be found uninfested particularly when little nest material is used. If such nests are infested the number of fleas present is often very small.

Sometimes nests built in holes may be very humid and this usually is reflected by large numbers of fleas occurring in them. Sand martin burrows for instance may be found teeming with fleas. CLAASSENS (1965a) collected 1,742 specimens of the subspecies C. styx jordani Smit, 1956, from five sand martin burrows taken at Little Island, Co Cork, Ireland in July, August and October, 1963. From three starlings’ nests situated in deserted sand martins’ burrows 4,025 specimens of C. g. gallinae were collected at Ballycroneen strand, Ireland, in June and July, 1964 (CLAASSENS & O'ROURKE, 1965). None of these nests were incubated. These results prove that C. g. gallinae thrives very well in nests where the humidity is very high. On the other hand C. g. gallinae may be found in dry airy nests of pigeons. ROTHSCHILD & CLAY (1952) commented that C. g. gal- linae is the flea par excellence of dry aerial nests. ROTHSCHILD (1952) noted: “Despite the wide range of hosts, C. g. gallinae is much more common in nests of birds which are built in holes and at some distance from the ground”. These statements seemingly contradictory in meaning indicate the wide range of tolerance of this flea to humidity. With Ash (1952) we would suggest that the nests of hole-nesting birds form a more congenial habitat for this flea than nests in a more exposed situation. But it is equally true that C. g. gallinae is often found in dry aerial situations. C. g. gallinae shares humid nests with C. garei and D. g. gallinulae, two species commonly infesting the nests of ground and bush nesting birds, provided these nests are not dry. On the other limit of tolerance to humidity C. g. gallinae is often found in company with C. fringillae and C. columbae, two species of flea which seem to prefer the dryer types of nests. To the former group we may add the rare Dutch flea Ceratophyllus borealis Rothschild, 1907, which in its distribution seems to be restricted by climatic and geological con- ditions. The group gallinae, fringillae and columbae may be extended with the

26 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

equally rare flea Ceratophyllus r. rossittensis Dampf, 1913, which is a monoxenous parasite of the crow, Corvus corone Linnaeus.

In table II, avian hosts are classified according to the four categories of nesting sites mentioned above. After each species of bird the number of nests examined from each nesting site and the number (in brackets) of nests infested are given. The host specific fleas of the Hirundinidae and the species C. columbae in nests of pigeons are omitted. Some nests of black birds are classified under different categories because these nests were found in a variety of situations. Under each species of flea recorded, the number of specimens found in the total number (in brackets) of nests infested with that flea are given.

One should be aware of the fact that any classification of this kind is very artificial because nests can be dry or wet in any of the four situations depending upon accidental local ecological circumstances.

is rarely found in large numbers, but C. g. gallinae may be present by hundreds in one single nest as we have shown earlier. Many specimens may sometimes also be bred from the nests. The author bred 1,064 specimens from one nest of a blue tit, Parus caeruleus, situated in a hole in a wall at Blarney, Co Cork, Ireland (CLAASSENS & O’ROURKE, 1965). On the days of collection, June 2nd, 1964, the nest contained only one female D. g. gallinulae. During incubation, which lasted from June 2nd until July 6th only five additional males and six females of D. g. gallinulae were obtained. ASH (1952) obtained 1,304 C. g. gallinae from a blue tits nest.

From table II it may be seen that the average number of fleas per infested nest is rather low for the subspecies D. g. gallinulae and C. g. gallinae. D. g. gallinulae

28 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 1, 1966

D. g. gallinulae seems to be fairly scarce in The Netherlands, where it has so far been found in five provinces. SMIT (1962a) commented that this species should be commonly present here as it is found in abundance in surrounding countries. We investigated 53 nests situated in bushes and hedges but we found that only three of these harboured D. g. gallinulae. Of 24 nests collected on or near the ground only three contained this species. D. g. gallinulae may experience a good deal of competition from C. garei which appeared to be very common in the nests of both ground- and bush nesting birds. C. gare? shares humid nests with C. g. gallinae too and may thus also be responsible for the relative scarcity of the latter species.

C. fringillae prefers dryer nests of the house sparrow, Passer domesticus, and starlings, Sturnus vulgaris, as well as the dry nests of other Passerine birds. Strangely enough we found 19 specimens in a very humid nest of a blackbird which was situated in ivy against a stone wall. It may be that this population of C. fringillae originated in the nest of a spotted fly catcher, Myscicapa striata, which reared young in the same ivy the year before. Its presence in the nest of a sparrow hawk, Acczpiter nisus, may have been the result of predation.

ROTHSCHILD (1958) found a seasonal variation with regard to the species of fleas infesting birds (migrants and residents) on Fair Isle. In spring 66% of all fleas found on migrant and resident birds were D. g. gallinulae and 16% were C. g. gallinae but in autumn the situation was reversed and C. g. gallinae became by far the most common species both on residents as on migrant species. ROTH- SCHILD suggested that the main dispersal period of D. g. gallinulae (and C. borealis) is the spring and of C. g. gallinae the summer and autumn. Indeed in summer C. g. gallinae may be found teeming in birds’ nests. CLAASSENS & O’ROURKE (1965), as was mentioned already, collected 4,025 specimens of this flea from three starlings’ nests in June and July (1964) and 1.064 specimens were bred from a blue tit’s nest during June, 1964.

Very few adult fleas were found by the author in the nests collected in Noord- Brabant and Limburg. It seems likely that adult fleas leave the hosts’ nests after the young birds have left in late summer or earlier. These manoeuvres undoubtedly increase the survival chances and dispersal of fleas. ROTHSCHILD (1958) found that spring migrants (199 specimens) had an infestation rate of 52,2% as compared with 2,7% of 615 autumn migrants. It may be that in autumn fleas are more active in searching for a sheltered place to hibernate while in spring they may become very eager to find a host.

SEX RATIOS IN BIRD FLEAS

In Table III the numbers of either sex of bird fleas collected and the percen- tages of males among them are listed. Some of the results are compared with those obtained by CLAASSENS & O'ROURKE (1965) for the same species collected in Ireland and with those obtained by AsH (1952) for specimens taken in Eng- land. The percentages of males among martin fleas are compared with results published by CLAASSENS (1965b), who studied these fleas in Ireland, and with those recorded by THOMPSON (1952; 1953) from Engeland and with the ones

recorded by DUNNET & ALLAN (1954) of martin fleas collected in Scotland. The figures pertaining the subspecies C. s. styx are compared with those of C. s. jordani Smit, 1955, collected in Ireland and with the percentages known for the species C. styx collected in England.

The species C. columbae is omitted as too few specimens were found. No comparative results were available for C. fringillae.

In bird fleas there is a definite predominance of females. Although with some species there is a wide range of variation in the percentages of the sexes recorded by diverse authors it seems likely that the average percentages shown in Table HI will be close to the prevailing situation in the nests of the hosts. ROTHSCHILD (1958) found a gradual increase of females on the birds of Fair Isle from spring until autumn. There was, however, a preponderance of male D. g. gallinulae on spring passage migrants. In July there was an excess of females on resident birds and on September and autumn migrants only females were found. In the nests of the Fair Isle birds ROTHSCHILD found a six percent majority of female D. g. gallinulae. Both the predominance of males of D. g. gallinulae on spring passage migrants and the low sex ratio of these fleas in the nests of the hosts are very unexpected and should make a rewarding object of further investigation. Females of C. g. gallinae outnumbered males both in the nests and on the bodies of the birds of Fair Isle, but on the hosts there was a gradual increase of females.

ROTHSCHILD (1958) drew the attention to the low ratio 48—50 in favour of female C. g. gallinae found in the nests of the common resident bird, the wheatear, Oenanthe oenanthe (L.), CLAASSENS & O'ROURKE (1965) reported an exceptional ratio 200 : 114 in favour of males in C. g. gallinae taken from a starlings’ nest collected at Ballycroneen strand, Ireland, in June, 1964. We do not know what ecological or genetic factors favour an unusual high production of males or result in the survival of more males than females.

The apparent predominance of females among adult fleas is no indication that fewer male flea embryos should be produced (primary sex ratio), nor that fewer male fleas hatch from cocoons (secondary sex ratio). Numerical preponderance of females may well develop in later stages of adult fleas. A collection of fleas from birds’ nests taken in February and March might well reveal a still higher sex ratio in favour of females. Females seem to outlive males by many months and can withstand adverse conditions to which males succumb. Males of many species of fleas are believed to die soon after copulation. A gradual increase of female fleas seems therefore natural especially on the bodies of the host since, after copulation, females lay eggs in batches, and each time before a fertile batch is laid the female reproductive organs require the stimulus of a blood meal (ROTHSCHILD & CLAY, 1952):

The greater hardiness of females may sometimes be responsible for their great predominance in collections made under artificial laboratory conditions. A pre- dominance of females was also found among stragglers of mammal flea species to birds’ nests. Of five species of mammal fleas collected from birds’ nests discussed here we found that of a total of 13 specimens nine were females. MEAD-BRIGGS & PAGE (1964) found that of 56 fleas other than S. cuniculi which were found as

stragglers on 30 out of 279 rabbits obtained throughout Great Britain, 38 were females and they noted that similar results were recorded previously from Kent.

SUMMARY

Nineteen species of mammals (336 specimens) and 204 nests of 45 species of birds were examined for fleas. In total 954 specimens (23 species) of mammal fleas and 12 specimens (2 species) of bird fleas were collected from the bodies of 174 mammals infested, while 63 specimens of the subspecies Monopsyllus s. sciuro- rum (Schrank), were taken from three nests of the red squirrel, Scaurus vulgaris Linnaeus.

From 77 birds’ nests found infested 2.997 specimens (nine species) of bird fleas were reared and 13 specimens (five species) of mammal fleas were obtained.

All this material was collected in the provinces of Noord-Brabant and Limburg, The Netherlands, mainly during the months of October, November and December, 1964.

Fifteen mammal fleas and five bird fleas were found to be new to Noord- Brabant and two mammal fleas and four bird fleas could be added to the list of Siphonaptera of Limburg. Thirteen species of birds and two species of mammals, viz. Sorex minutus Linnaeus and Mustela lutreola (Linnaeus) were added to SMIT’s (1962a) lists of hosts for Dutch fleas. For 23 flea hosts recorded in SMIT (1962a) new flea-host-associations were found.

The ecology, host- and nest specificity, sex ratios and economic importance (do- mestic infestations, veterinary and medical importance) of fleas were discussed.

In a synopsis of Dutch fleas every species is followed by the names of the pro- vinces from which it was recorded by SMIT (1962a) and our records for Noord- Brabant and Limburg were added and marked with an asterisc.

Mammal fleas were dealt with under the relevant mammalian hosts examined. Bird fleas were first listed in a synopsis of material collected so as to make exact recording possible. In a further discussion of these fleas special attention was paid to their host or nest site specificity.

Sex ratios in bird fleas were compared with results recently obtained by the author and by other students of fleas.

HARVARD UNIVERSITY THE GROUP OF PSENULUS PULCHERRIMUS (BINGHAM)

(HYMENOPTERA, SPHECIDAE) BY

| oe sa VAN LITH Rotterdam, The Netherlands

Abstract

The distribution in the Indo-Australian and East-Asiatic regions of the group is discussed. The material studied originates from localities in a triangular area formed by Gujarat in the West, Japan in the North and northeastern Australia in the South. The subgenus Eopsenulus Gussakovskij, 1934, was erected for Psenulus iwatai Gussakovskij, 1934 (Japan). This form is regarded here as the Japanese representative of the group of Psenulus pulcherrimus (Bingham, 1896). The provisional classification as a group is preferred as long as other subgenera of Psenulus are not yet defined. The relationship between the forms from western India and those from northeastern Australia is very close; P. carinifrons Cameron, 1902 (Deesa) and P. scutellatus Turner, 1912 (Queensland), are considered to be subspecies only. Even P. iwatai may prove merely to be a subspecies of the Indian form. P. sinclairi Lal,

- 1939 (Bombay), which could not be examined, and a probably new subspecies from South India, are also very closely related to P. carinifrons. A key to the species and subspecies is provided. The distribution of the eleven forms is given, together with new records of the species already treated in a previous paper. One new subspecies from New Guinea is described.

In a study on Psenulus (Van Lith, 1962) I have provisionally divided the Indo-Australian species (about 70 species and subspecies from this region have been described) into a number of groups, in order to facilitate the future definition of subgenera. GUSSAKOVSKIJ (1934) described the subgenus Eopsenulus for Psenulus iwatai Gussakovskij (Japan). This species differs very much from the other East-Asiatic congeners in having a narrow and protruding carina between the antennae. It is evident now that the group of P. pulcherrimus is identical with the subgenus Eopsenulus Gussakovskij. The characters of the latter group are: a slender body, a narrow and protruding carina between the antennae, a largely or completely black scutum, an almost interstitial first recurrent vein of the fore wings, and the female with triangularly or bluntly protruding anterior margin of clypeus and narrow pygidial area. There is a great contrast between the females and the males in the sculpture of the back of the propodeum, viz., almost smooth in the female and coarsely reticulate in the male.

It seems premature to delimit more subgenera of Psenulus; therefore I prefer to use in this paper the provisional term “group of P. pulcherrimus”.

During the last few years I received material from a larger area than that studied in 1962 and this brings the total number of species and subspecies of the group to ten, probably eleven. The components are distributed over a large triangular area, reaching from Gujarat in India, northward to Japan and from there south-

ward over New Guinea to northeastern Australia (Fig. 2). It is interesting that the forms from the outer angles of this area are not only closely related but even conspecific (P. carinifrons carinifrons (Cameron), from Gujarat and P. carinifrons scutellatus Turner, from northeastern Australia) or probably conspecific (P. zwatai from Japan). There is one “island” in this area, formed by the range of distribution of P. sogatophagus Pagden, the female of which is different, having one tooth more on the mandibles; this species has been found in Malaya, Thailand and Assam. Another species, P. pulcherrimus (Bingham), showing distinct specific differences, with more pointed clypeus and red gaster, inhabits Tenasserim, and has a subspecies, P. pulcherrimus projectus Van Lith, in Java. The two subspecies, P. carinifrons xanthognathus Rohwer and P. carinifrons rohweri Van Lith, seem to be closely allied and are characterized in the male sex by the coarser carination of the back of the propodeum. They occupy the large area formed by Malaya and the Indonesian islands (P. carinifrons robweri), and the Philippines (P. carini- frons xanthognathus).

Some of the forms of the group of P. pulcherrimus are somewhat variable as to the extent of the yellow marking, especially on the pronotum and the scutellum, and also on the fore and mid femora. Examples of the variation of the markings of the thorax in females of P. sogatophagus are presented in Fig. 3 and 4 and of the variation in two males of P. carinifrons scutellatus in Fig. 6 and 7. The fact that the Bornean specimens of P. carinifrons rohweri all have darker legs than those from the more southern islands, may be of a greater systematic value and I am not excluding the possibility that they represent a different sub- species. The males of P. carinifrons xanthognathus which I studied from the neighbouring island of Mindanao, have also darker fore and mid femora than the specimens from the northern Philippine Islands. Apart from the colour of the gaster there is a great resemblance between the females of rohweri and xanthogna- thus. However, more material, especially from the southern Philippines and from Borneo would be very welcome for getting a better idea of the distribution of the forms and their true systematic status. The total number of specimens examined for the present study is limited, viz. 230, originating from 21 different islands and continental countries.

The new subspecies from New Guinea is presumably a near relative of P. carinifrons scutellatus Turner (NE Australia). The former is very dark and in the latter the pronotum is often also darkened in both sexes, sometimes even com- pletely black.

In 1939, K. B. Lat described Psenulus sinclairi from Bombay, apparently from one single male. I was not able to examine the holotype but from Lat’s drawing it is evident that his species belongs to the group of P. pulcherrimus and is closely alied to P. carinifrons. From South India a single male of P. carinifrons is known which may be a different subspecies, as the puncturation of the scutum is coarser than usual. More material of both sexes from these localities is necessary to deter- mine the status of these males.

A key to all the East-Asiatic and Indo-Australian species of the group, is given below. It is followed by a discussion of most of the forms, and some new data on

The type from Amherst (Tenasserim) is in the collection of the British Museum (Natural History), London. It seems to be the only specimen known so far.

Psenulus pulcherrimus projectus Van Lith

1962, Van Lith, Zool. Verh. 52: 102—103.

A fair number of specimens was recorded in 1962 from East and West Java and also a female from Krakatau. There are no new records.

Psenulus sogatophagus Pagden

1933, Pagden, Trans. Royal Ent. Soc. London 81: 97—101. 1962, Van Lith, Zool. Verh. 52: 109—110. 21963, Tsuneki, Etizenia, Fukui Univ. 4: 15—16 (P. carinifrons).

This species closely resembles P. carinifrons rohweri, having a black gaster and the tendency to reduction of the yellow markings of the thorax (Fig. 3 and 4). The female is easily distinguished from P. carinifrons by the quadridentate mandibles; the clypeus is somewhat less protruding. In the male the back of the propodeum is less coarsely carinate than in P. carinifrons robwert; the last antennal segment is less flattened and less pointed than in P. carinifrons.

Hitherto this wasp was only known from one locality in Perak, Malaya. I re- ceived for identification from Prof. IwATA a female from Thailand which I could compare with a paratype from Malaya; undoubtedly it also belongs to P. sogatopha- gus. It was collected at Prew, 10 Jan., 1963, by A. NAGATOMI (HUA). The yel- low marking on the pronotum is slightly reduced medially and laterally; the yellow marking on the scutellum is larger, covering the posterior half and medially pro- duced triangularly so that it reaches the anterior margin (Fig. 4).

It is possible that the male mentioned by TSUNEKI (1963) from Thailand (Pakpanang), 14 July, 1961, coll. K. lwata (HUA), belongs to the same species and not to P. carinifrons rohweri.

The species seems even to occur also in Assam. I have studied two males from Chabua, 29 Oct., 1943, coll. D. E. HARDY (USNM). They have a nearly black pronotum, the lower half of the pronotal tubercles is yellow whilst the scutellum and the metanotum are black except the reddish-black posterior margin. The identification should be confirmed, however, by the capture of a female in this locality.

P. iwatai is the Japanese representative of the group. It is easily recognized by the completely black thorax (except the pronotal tubercles which are brownish) ; the legs for the greater part are yellow. In P. carinifrons extremus from New Guinea the thorax is nearly completely black but the legs are much darker than in the Japanese form.

J. P. van LITH : The group of Psenulus pulcherrimus 43

The inner tooth of the mandibles is very distinct.

I suppose that P. zwataz is closely allied to P. carinifrons and probably is a sub- species of the latter. It is advisable, however, to defer a decision until more material will become available.

The subgenus Eopsenulus which Gussakovskij created for this Japanese species should certainly include the whole group of P. pulcherrimus.

Psenulus carinifrons carinifrons (Cameron)

1902, Cameron, J. Bombay Nat. Hist. Soc. 14 : 288—289, 4 (Psen cerinifrons). 1962, Van Lith, Zool. Verh. 52: 103—104.

There are two males in the British Museum (Natural History), collected by Col. C. G. NURSE. One is the holotype (no. 21.834) bearing the label “Deesa 6.98”; the paratype is labelled ‘“Deesa 6.97”. Deesa is situated in Gujarat, India.

In the holotype the red anterolateral parts of the second gastral tergite are confluent; in the paratype these red markings are well-separated. The fore and mid trochanters and the fore and mid femora are completely yellow, the hind tibiae are for the greater part yellow, only about the apical seventh part somewhat brown.

The female is unknown.

P. sinclairi Lal from Padegaon, Bombay, is certainly closely related. As the col- lecting localities of P. carinifrons and P. sinclairi are not so far distant one from the other, further study of the latter holotype and of females from both localities would be interesting.

Psenulus carinifrons scutellatus Turner

1912, Turner, Ann. & Mag. Nat. Hist. [8} 10: 54, 9 (Psenulus ? scutellatus). 1916, Turner, Ann. & Mag. Nat. Hist. [8] 17: 128 (Neofoxia scutellatus). 21917, Turner, Mem. Dept. Agric. India 5: 173 (Neofoxia scutellatus).

1962, Van Lith, Zool. Verh. 52: 108 (Psenulus scutellatus).

In the female of this subspecies the transverse carina below the antennae is only slightly raised, but still distinct, whereas in the other forms of the ‘group this carina is hardly visible. The course of the recurrent veins of the fore wings often varies somewhat in Psenulus; apparently it is also the case in this subspecies, the first recurrent vein being interstitial in the female from Halifax whilst in the female from Cairns, according to the original description, this vein ends just in the second submarginal cell. The extension of the yellow markings on the thorax is also very variable.

Female. — In the holotype from Cairns the pronotum is black, also the pronotal tubercles are black. In the female from Halifax only the outer ends of the pronotum are darkened, the pronotal tubercles are yellow.

In the female from Cairns the scutellum has a yellow band on the hind margin about half as broad as the scutellum, whilst in the female from Halifax (Fig. 5) the scutellum is almost completely yellow with the exception of a narrow anterior margin. Only the median part of the metanotum is yellow in the female from Cairns but the metanotum is completely yellow in the female from Halifax.

44 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 2, 1966

Male. — In the male collected by VEITCH in N Queensland the yellow band on the pronotum is somewhat reduced laterally; the pronotal tubercles are yellow. In one of the males from Halifax the dorsal yellow band of the pronotum is reduced to two long patches; in another male from this locality, collected on the same day, the pronotum is completely black (Fig. 6 and 7). In the latter specimen the yellow mark on the pronotal tubercles is slightly reduced.

In both males from Halifax the dark brown anterior margin of the scutellum is somewhat broader than in the female from this locality, especially on the sides. In the male from Cairns the fore part of the scutellum is not visible. In all males the yellow marking of the metanotum is more or less reduced laterally.

The fore and mid legs including the trochanters are yellow in both sexes. In the female about the basal half of the hind tibiae is yellow; in the male about two- thirds of the tibiae are yellow. The gaster is always completely black.

TURNER (1912) correctly remarked that this form, as well as P. interstitialis Cameron, differs from what he called the true Psenulus. In 1917 he also recognized P. xanthognathus Rohwer from Luzon as a closely allied species. I have not seen the female from Dacca (N India), mentioned by TURNER (1917) and provisionally named P. scutellatus, but I suppose that this will prove to be another subspecies. According to TURNER the insect from Dacca is nearer to the Queensland than to the Luzon form.

In 1962 I left the possibility open that P. scutellatus Turner and P. carinifrons rohweri Van Lith might prove to be synonymous. After the study of the afore- mentioned material from Australia and taking into account the difference in the sculpture of the hinder part of the propodeum in the males of the two forms, I now think that they are different subspecifically.

This seems to be a common species in the Philippines but nevertheless the following new records since 1962 may be of interest.

The female from Manila has completely yellow fore and mid trochanters and

J. P. VAN LITH : The group of Psenulus pulcherrimus 45

femora, as seems to be the rule in the females from Sibuyan and Negros. This proves again the variability of at least one of the species.

The abovementioned specimens from Mindanao show a distinct reduction of the yellow markings, in accordance with what I have found earlier. Only the basal 3/5 or 2/3 of the hind tibiae are yellow. In the females the pronotum, scutellum and metanotum are completely yellow but in the male from Lake Lanao the yellow markings of the pronotum and of the metanotum are reduced laterally, whilst the scutellum is darkened anteriorly. There is some difference in the extension of the red spots on the second gastral tergite, which are confluent in the female from Zamboanga del Norte, but separated, indistinct, and much darker in the female from Lake Lanao.

Psenulus carinifrons rohweri Van Lith

1962, Van Lith, Zool. Verh. 52: 108.

This subspecies differs from the Australian P. carinifrons scutellatus, in which the gaster is also completely black in both sexes, by the larger extension of the yellow colour on the hind tibiae and by the more coarsely carinated back of the propodeum of the male.

Although this form has not been collected in large series it does not seem to be very rare; it has a comparatively large area of distribution, covering Malaya, Su- matra, Java, Kangean Islands, Buru and Borneo. Here are some new records from Java and Borneo.

Java: 2 4, Gopeng (= Kopeng?, E Java, Res. Semarang), coll. H. H. BANKS (OUM).

North Borneo: 1 2, Keningan, 12—17 jan., 1959, coll. T. C. Maa; 1 6, SE North Borneo, Forest Camp, 9.8 km. SW of Tenom, 19 Dec., 1962, coll. Y. HIRASHIMA (BISH).

In the Bornean specimens the legs are blacker than in the wasps from Java, the Kangean Islands and Buru. In the abovementioned female and male from Borneo all trochanters are black and the basal half or even a greater part of the fore and mid femora is black whilst in the Javanese form the fore and mid trochan- ters and femora are yellow. About three quarters of the hind tibiae are yellow which is also less than in the more southern material. The pronotal yellow band shows some lateral and median reduction.

Because the material is too restricted I hesitate to consider the Bornean specimens as a separate subspecies and have provisionally labelled these P. carinifrons rohweri. It is to be hoped that a later revision, based on good series, preferably from Malaya, Sumatra and Borneo, may solve this problem.

Psenulus carinifrons extremus subsp. nova

Female. — Head black, scape of antennae brown, foreside partly yellow, under- side of flagellum brown. Mandibles yellow except brown base and reddish-brown tips. Palpi testaceous.

46 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 2, 1966

Thorax and gaster black, only posterior half of scutellum and median part of metanotum brownish-black. Pronotal tubercles and tegulae dark brown. Fore and mid femora and trochanters brown, ends of femora yellow. Fore and mid tibiae yellow, basal half of fore and mid tarsi yellow. Basal third of hind tibiae paler yellow, apical thorns yellowish. Veins of wings brown.

Frons indistinctly not densely punctate, slightly convex on either side of frontal carina. Vertex shining, punctures minute, hardly visible (30 X). Thorax shining, punctures sparse and not sharp. Back of propodeum smooth, sides with fine and densely reticulate carination.

Pubescence of face silvery, mostly appressed below antennae. Pubescence of rest of body whitish, rather dense on mesosternum, last apical sternite and apices of hind tibiae.

Male. — Fore and mid legs brown, including trochanters, but outer end of trochanters somewhat yellow, also underside of fore femora, greater part of fore and mid tibiae and fore tarsi except last segment yellow. Hind tibiae dark brown, base paler brown. Apical thorns of hind tibiae pale yellow.

Propodeum with almost smooth base behind enclosed area, back of propodeum with dense irregular carination, not as coarse as in P. carinifrons xanthognathus.

This subspecies is very similar to the Australian subspecies, P. carinifrons scutel- latus, but it is easily recognized by the almost completely black thorax in both sexes. The legs are much darker than in any of the other subspecies.

Psenulus sinclairi Lal 1939, Lal, Indian J. Ent. 1: 49—50, 2 (recte: 3).

Original description: “Female. — General colour of body dark.

Abdomen long, oval, segments with silvery white pubescence disposed in oblique curves diverging towards sides, except transverse narrow apical stripes of segments II, III and IV, ovipositor short. Length 7 mm.

Holotype obtained from the burrow of a stem borer in sugar cane at Padegaon, Bombay. Coll. G. S. KARKHANIS. (C.S. 79. 5.11.1937). It is deposited in the Pusa collection (H/7481).

Unfortunately I did not have the opportunity to examine the holotype. From the description and from the drawing representing the whole wasp (X 9) it is evident that it is a male, not a female; the author must have been misled by the gastral spine.

There is no doubt that this wasp is closely allied to P. carinifrons. The localities where P. sinclairi and the holotype of P. carinifrons have been found are not very distant. The description does not say anything, however, about the red parts of the second gastral tergite which are conspicuous in the nominate form. If the gaster is indeed fully black it is probable that the male described by Lat is a distinct subspecies of P. carinifrons. It certainly is also closely related, perhaps even identical with the male from Coimbatore mentioned in this paper as a probable subspecies of P. carinifrons. I prefer to defer a decision until also the females of these forms are known; an examination of the mandibles of the females would then be necessary to ascertain whether these are quadridentate as in P. sogatophagus or tridentate as in the other forms of the group.

Psenulus carinifrons subsp. nova?

A male from South India differs from the nominate subspecies in the following details: the base of the second tergite is indistinctly reddish coloured. Pronotum dorsally completely yellow. Basal half of fore and mid femora black or dark brown (trochanters yellow). The apical fourth of the hind tibiae is dark brown. Scutum strongly punctate. Frons slightly stronger punctate than in nominate subspecies.

The carination of the back of the propodeum seems to be coarser, but this part being covered by the wings, a good comparison was not possible.

As only one specimen is available and therefore only one sex could be studied, it seems to be premature to separate this form, although the strong puncturation of the scutum will probably prove to be a good character. The darkening of the fore and mid femora may be less important as this often also occurs in the Philippine subspecies xanthognathus whilst I have seen one or two females with completely yellow trochanters and femora. Also in P. carinifrons rohweri the colour of fore

48 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 2, 1966

and mid femora may vary. In how far this is related with insular isolation remains an interesting subject for later study after sufficient material would become available. For the present we shall have to be contended with the few specimens scattered over collections in the Old and in the New World.

Apart from the somewhat reddish second gastral tergite this subspecies closely resembles P. carinifrons rohweri. However, the scutum of the latter form is much finer punctate. Also P. carinifrons xanthognathus is closely allied but also has a slightly weaker puncturation of the scutum and the frons is more convex.

It is possible that the specimen from Coimbatore and P. sinclairi Lal from Bom- bay — no females from either locality are available — are identical but un- fortunately I could not study the holotype of the latter form.

MICROLEPIDOPTERA by

HARVARD Abstract UNIVERSITY

In this paper two genera and 22 species of Microlepidoptera from South Asia, belonging to the families Tortricidae, Xyloryctidae, Oecophoridae and Ethmiidae are described as new, viz. Cimeliomorpha g.n. (type: Copromorpha cymbalora Meyr.), Thymiatris seriosa, scolia and microloga, Coenorycta plutotera, anholochrysa and acrostega, Odites sphaerophyes, Casmara regalis, phobographa, uniata, rufipes, rhodotrachys, kalshoveni, Tonica syngnoma, pharmacis, centroluta, peripsacas, melanoglypha, Ethmia submersa, Agrioceros subnota, Chrysethmia g.n. hypomelas (type) and neogena. One new name (Cryptophasa antalba, Xyloryctidae) is proposed and three noteworthy species are recorded (Xyloryctidae, Glyphi- pterygidae and Oecophoridae); finally a lectotype is selected for Tonica effractella (Snellen, 1879), while the genus Tonica Walker, 1864, is treated more extensively.

Wing neurations and heads of the new genera and genitalia of the new species, where available, of the two sexes, are figured.

When studying several collections of South Asiatic Tortricoid Microlepidoptera I encountered striking, apparently new, species from other families. Some were so fascinating that I described them on the way. Besides, several descriptions of Xyloryctidae have been made, preliminary to an intended revision of this family; as other duties will delay that revision, I prefer to publish now the descriptions already made.

The material treated in this paper originates from the British Museum (Natural History), London (BM), and from the Leiden Museum (LM). Of especial interest is the excellent material, collected by my friend, the late J. P. A. KALIS, in 1937, in the hardly ever searched regions of Western Central Celebes, and in 1938, in southwest Celebes; it was preserved in the Rothschild Collection, Tring, and is now transferred to London.

I am indebted to the Trustees of the British Museum (Natural History) for the permission to work their material, to retain a few duplicates for the Leiden col- lection, and to publish the results in the present series. Furthermore I am very grateful to the following gentlemen for their kind assistance in many ways during my studies at the British Museum and at Tring: Messers. W. H. T. Tams, J. D. BRADLEY, P. E. S. WHALLEY, M. SCHAFFER, W. TREMEWAN and D. CARTER. Where not otherwise indicated, the material is in the Leiden Museum.

Some of the figures, made by Mr. A. C. M. van Dijk, have been financed from a grant for which I am indebted to the Netherlands Organisation for Tropical Research (WOTRO). Other drawings have been made by Mr. W. BERGMANS, of this Museum, and by the author.

Two genera and 22 species are described as new and three species are recorded below. A lectotype for Tonica effractella (Snell.) is selected.

Thymiatris microloga spec. nov. Fig. 4

4 37—41 mm (holotype 38 mm). Head dull pale ochreous, collar shining pale ochreous. Antenna light ochreous, ciliations about 11/3. Palpus pale ochreous, median segment along basal half of upper side with a brown streak, by far ex- ceeding base of antenna, 21/5 X as long as terminal segment. Thorax snow-white, dusted irregularly with dark fuscous-grey. Abdomen pale golden-ochreous, glossy, dorsal bands of spines golden-orange. Legs pale ochreous mixed with brown hairs, spurs brownish.

Fore wing narrow, elongate-truncate, costa slightly curved at extremities, gently concave in middle, almost straight, apex rounded, termen gently rounded, almost vertical. Pure white, dusted coarsely throughout with dark fuscous-grey; a continuous streak of the same colour along costa, narrowed in middle, confluent with a similar but narrower irregular streak along upper edge of cell; veins above and beyond cell, as far as vein 2, narrowly streaked with the same colour, as also is the discoidal vein; sometimes an inwardly-oblique series of short darker streaks along veins, this series running from costa before apex to dorsum well before tornus. A series of rather large pale ochreous spots on ends of veins 3—9, becoming smaller on both ends of the series, surrounded by brownish- ferruginous scales. Cilia pale ochreous with a paler base and a dark brown sub- median band, posterior half of cilia rather mixed with brown, cilia in tornus white dusted with dark fuscous-grey.

Hind wing glossy ochreous-grey, along upper part of termen and in apex nar- rowly pale ochreous strewn with dark brown. Cilia light ochreous-fuscous, with a distinct dark fuscous subbasal narrow band.

Male genitalia. Similar to those of T. melitacma Meyr., but differing thus. Valva shorter, with cucullus much more narrowed and pointed, also more curved. Aedea- gus half as long as in melitacma. Aedeagus shorter.

East Java, Tengger Mountains, Nongkodjadjar, 1300 m, 19.X1.1938 (A. M. R. WEGNER), 1 &, holotype, gen. no. 4628; 2 ¢, paratypes.

Closely allied to the type-species, T. melitacma Meyr., from India, but with the veins 4 and 5 of the fore wing separate and the genitalia different. Nearest to a new T’hymiatris species from the Philippines, but with the forewing more suffused and with the valva differently shaped.

Cryptophasa antalba nom. nov.

Cryptophasa proleuca Diakonoff, 1948, Treubia 19: 191, t. 6 fig. 8; nec Meyrick, 1890, Trans. Roy. Soc. S. Austral. 13 : 31 (Cryptophaga).

As the generic name Cryptophaga Meyrick, 1890, is an emendation of Crypto- phasa Lewin, 1805, I am now satisfied that the above name proposed by myself is invalid, being a junior primary homonym; therefore I am proposing the above new name for this species.

Simaethis nubicincta Meyrick, 1938, Iris 52 : 52, 86 (Java, 9). — Clarke, 1955, Meyrick’s Types 1: 219.

This somewhat surprising synonymy became apparent to me when studying the Glyphipterygidae in the British Museum in 1946. Later I had the opportunity to compare the lectotype of mormopa (selected but not yet published, by Dr. J. F. GATES CLARKE) and the holotype of nubicincta. They are one and the same, very distinct, species.

Male genitalia. Uncus pointed, sickle-shaped. Socius short, free, subporrected. Valva strongly concave, sacculus thickened, moderately haired, unarmed; cucullus curved outwards, narrow, strong. Lobi anales broad, flat, tops rounded and dilated. Aedeagus moderate, sinuate (gen. no. 4791).

Valva short, broad at base, sacculus over 1, top forming a free lobe, dentate or simple, cucullus thinly haired, suboval. Aedeagus sclerotized, straight, acutely pointed, with longitudinal ridges, sometimes denticulate, and a lateral denticulate prominence.

Female genitalia, Eighth sternite moderately sclerotized, densely haired along upper edge. Ostium, a diversely shaped oblique cup, colliculum very short. Ductus and corpus bursae simple.

The genitalia show only slight specific differences, which are sufficient, though, for discrimination of species. Superficial differences usually are more striking.

A. DIAKONOFF : South Asiatic Microlepidoptera 61

The species are rather similar, very large insects with narrow, long wings and long legs, often thickened with brushes or whorls of dense scales. The scaling of the palpi and of the legs show differences which must be only specific, for the neuration and the genitalia are extremely similar in all the species.

Malaya, Pahang, Tras, 1912 (Popp), 1 2, from Meyrick Collection (BM), named “Tonica nigricostella Snell.” by MEYRICK; gen. no. 4718. This unexpected identification with a completely different species apparently is due to a curious error: MEYRICK thought that T. wigricostella Snell. had been described after a male, while SNELLEN’s type specimen actually is a female. So there is no question of SNELLEN’s migricostella and the present female specimen being conspecific.

Type-species, Chrysethmia hypomelas spec. nov. (Celebes).

A natural group of tropical species with characteristic compact male genitalia, quite dissimilar from those in Ethmia Hubn., to which genus the golden-yellow, black-dotted species have been attributed until present. They are closer allied with Agrioceros Meyr., described from the Philippines which is intermediate and forms the connection with Ethmia.

Ethmia zelaea Meyrick, 1906, Journ. Bombay Nat. Hist. Soc. 17: 409 (4, Ceylon), also belongs to the present genus. The genitalia have been illustrated by CLARKE, 1965 (Meyrick’s Types 6: 433, t. 214 fig. 3a—b).

THE BIOLOGY OF CASMARA KALSHOVENI DIAKONOFF, AN OECOPHORID BORER

BY

L. G. E. KALSHOVEN Blaricum, the Netherlands

The borer infestation was detected by the Javanese personnel of my temporary entomological field laboratory at Gedangan (KALSHOVEN, 1955), at a time when particular attention was being paid to the borers in green stems and trunks in the cultivated teak woods of Central Java. The borer larvae were found in the shoots of the small-leaved, wild form of Murraya paniculata Jack. (Rutaceae; vernacular name ‘djenar’, cf. HEYNE, 1950). This is a small tree or shrub up to 6 m high, not uncommon in the area.

After the attack had been discovered through the occurrence of dying and dead shoots, it was observed from November, 1932 to May, 1933. A total of 84 infested shoots and branches, 1—4.5 cm thick, were collected from some 14 trees.

The shoots were bored from immediately below the top or from a lower part downwards over a length of up to 65 cm, mostly in the ligneous parts. Once in a single 2.5 cm thick branch three parallel tunnels in the core were found. In the trunk of another tree, 4.5 cm in diameter, the tunnel ran immediately under the bark. Small black holes from which sap had flown, were visible along the infested parts. According to the collector no frass was seen attached to the branches, the excreta apparently being ejected in loose particles. As a rule the remaining foliage on the branches was still green or withering.

During a visit to the laboratory at the end of October, 1932, I made the fol- lowing notes. The larvae live in narrow, black-walled, longitudinal tunnels (T. 1 Fig. 2). They are slender, with yellowish thoracic segments, the abdomen is isabel- coloured, the pronotal shield is of a curious shape, the last abdominal segment being flattened and strongly sclerotized. The initial stage of the attack was not observed. The smallest larva collected was 25 mm long, 3 mm broad, the largest 48 mm X 5 mm.

The clipped shoots were placed in water. Some larvae were moved to a hole in a freshly cut ‘djenar’ branch. Moving some other larvae to fresh cassava tubers (Manihot utilissima, rich in amylum) — method used with some success in raising young larvae of the Cossid Xyleutes ceramica (Walk.) — failed altogether in the present case.

Mature larvae pupated readily indoors in the tunnels. Pupae were encountered in the field from the end of November to mid December. Moths emerged between 20 December and 10 May. Notwithstanding considerable mortality, particularly in the larval stage, 19 moths altogether were bred in the laboratory.

Shoot-boring habits have already been recorded in some Oecophoridae in India. T. B. FLETCHER (1917) described the life-history of Tonica niviferana Walk., a borer in the shoots of Bombax malabaricum DC. (Bombacaceae) and illustrated

88 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 3, 1966

it with a nice coloured plate. The borer is not considered to be a real pest, though its activities have stunted young growth in cultivations. The same species was dealt with by BEESON (1941). Judging from the particulars given, its habits differ strongly from those of the Murraya borer. In addition to this, BEESON has listed] a second Oecophorid borer, viz. Allotalanta triocellata (Staint.), which lives in the shoots of Anthocephalus chinensis (Lamk.) Rich. ex Walt. [Rubiaceae, = A. cadamba (Roxb.) Miq.}. The larvae of five other Indian species, mentioned by BEESON, have different habits, some feeding on leaves spun together, others being case-bearing defoliators.

SOME ODONATA OF RAPA ISLAND, WITH DESCRIPTIONS OF THREE POLYNESIAN SPECIES OF ISCHNURA CHARPENTIER

BY

M. A. LIEFTINCK

Rijksmuseum van Natuurlijke Historie, Leiden

Abstract

The writer reports on a collection of Odonata from the South Sea island of Rapa. Among the 4 species recorded, one, Ischnura thelmae spec. nov., is described from both sexes as new. Two other members of the same genus, previously only known from the types, are I. spini- cauda Brauer, 1865 (Polynesia) and I. taitensis Selys, 1876 (Tahiti). These are re-characterized and figured, the last-mentioned species after fresh topotypical material from the Society Islands. I. cheesmani Fraser, 1942, also from Tahiti, is considered synonymous with I. ¢a/- tensis Selys.

The present paper deals with a small collection of Odonata made in the island of Rapa, in the South Pacific, by Dr. J. F. GATES CLARKE and his wife, Mrs. THELMA M. CLARKE. The main object of this visit was to investigate the micro- lepidoptera of that remote island, but fortunately other insects were also collected. This trip was undertaken in 1963 in behalf of the United States National Museum, Washington D.C., and made possible by a grant supplied by the Office of Naval Research. I am much indebted to the authorities of the above museum, particularly Messrs. J. F. GATES CLARKE and OLIVER S. FLINT, Jr., for the privilege of exam- ining this material, which includes a species of Ischnura apparently new to science. The receipt of this collection offered a welcome opportunity to re-characterize at the same time two other species of Ischnura also reported from the South Pacific. These species, of uncertain status since the time of their description, are I. spinicauda Brauer, 1865, and I. taitensis Selys, 1876, both of them hitherto known only from the types. A re-examination of the former was made possible by the courtesy of Dr. Max BEIER, of the Naturhistorisches Museum, Vienna; Dr. G. DEMOULIN has been kind enough to lend me the types of I. taitensis from DE SELYS’s collection in the Institut royal des Sciences Naturelles at Brussels. I wish to express my best thanks also to Dr. J. L. GRESSITT, of the Bernice P. Bishop Museum, Honolulu, for his continuous help and generosity in letting me study the extensive collections of Odonata accumulated by him and his co-workers in various parts of the Indo- Australian and Pacific areas.

The following information is based on the results of the “St. George” Expedition to the South Pacific whose members, Mr. C. L. COLLENETTE and Miss C. E. LONG- FIELD, were probably the first to make entomological collections on Rapa during

89

their stay on the island, from April 10 to 18, 1925. Miss LONGFIELD very kindly furnished me with several interesting publications giving full details of Rapa and other southern Pacific islands. I have selected a few of the most important amongst these for inclusion in the list of references, COLLENETTE’s fascinating book, so well illustrated by Miss LONGFIELD, being certainly most helpful in visualising the conditions met with by these explorers.

RAPA ISLAND

The next particulars of the oceanic island of Rapa (also known as Oparu) are extracted in part from an article on its flora by L. A. M. Rırky in the Bulletin of Miscellaneous Information, no. 2 (1926), issued by the Royal Botanic Gardens, Kew.

Rapa is situated in 27° 36 S., 144° 17 W., and is five miles in length by four in breadth. It is of volcanic origin with steep jagged peaks, the highest of which rises to 2077 feet. In shape it resembles a misshapen letter C, thickened towards the north and south, with the interior occupied by Ahurei Bay, which fills the bed of an ancient crater and opens to the sea on the eastern side. Excellent maps and photographs of its topography are contained in COLLENETTE (1925) and CHUBB & SMITH (1927). The island is little visited by vessels and, according to the first author, the natives still use the candle-nut (Aleurites moluccana) for illumination in preference to oil. As COLLENETTE writes, the neighbourhood of the village of Ahurei presents little of botanical interest, but the island possesses many streams, which are utilised on the lower ground for the irrigation of extensive taro beds (Colocasia), the principal food of the inhabitants. The greater part of the hill slopes are covered with a growth of short grass and a species of fern, larger growth being kept down by grass fires and by the high winds which bend and deform any isolated unsheltered trees. Thick vegetation clothes some of the higher peaks, the sheltered and damp gullies down to sea level, and the slopes of detritus at the foot of cliffs. At about 500 feet a tree-fern makes an appearance, becoming more plentiful as the elevation increases and eventually completely dominating all other trees.

To appreciate the remoteness of this little island reference should be made to a map. Associated with Rapa at some distance are the much smaller Marotiri and the Neilson rock and reef; otherwise the next neighbours are the Austral group (Tubuai Is.), the nearest 250 miles distant, but these are also mere scattered specks, and the Cook group at 800 miles no better. It may be added that the Society Islands (with Tahiti and Borabora) and the Tuamotus are situated about 750 miles toward the north, Pitcairn almost 900 miles due east-northeast, Samoa being about 1600 miles, Fiji almost 2000, and the Kermadec group approximately 2100 miles away.

As far as I am aware no dragonflies have yet been recorded from Rapa. With the exception of the new Ischnura, which in all probability is endemic in the island, all specimens contained in the present collection belong to species having a very wide distribution.

M. A. LIEFTINCK : Odonota of Rapa 91

LIST OF SPECIES Coenagrionidae

Ischnura a. aurora Brauer, 1865 (Fig. 3)

Material. — 18 &, 15 2, Rapa, Haurei, 6-16 and 28.IX.1963.

All females belong to the heterochromatic, dark colour form.

This little dragonfly is a wind-borne species, breeding in stagnant waters of every kind. Originally described from Tahiti it is distributed far beyond its many oceanic settlements, ranging from northwest India and Ceylon through southeast Asia, Australia and New Zealand. Chiefly coastal throughout the South Sea islands and elsewhere, I. aurora also has a number of isolated montane habitations in parts of Java and New Guinea, where it seems to have firmly established itself. Remark- ably enough, a distinctive subspecies, lacking blue markings on the terminal seg- ments of abdomen, has developed in the mountain valley of the Baliem River (Central North New Guinea) and occurs nowhere else on that continent. A second red-bodied Ischnura, nearly related with I. aurora but specifically distinct there- from, was discovered in the Arfak Mountains of the Vogelkop, in West New Guinea. For further particulars, including references, notes on the distribution, and an account of the larvae of some species, see LIEFTINCK (1949, 1959 and 1962).

Ischnura thelmae spec. nov. (Fig. 1) Material. — A small series comprising both sexes, described hereafter.

Libellulidae

Diplacodes bipunctata (Brauer)

Material. -- 31 4, 26:9, Rapa, Haurei, 8-28.IX and 1-28.X.1963.

This is also a common and wide-ranging dragonfly, from the Moluccas eastward far into the Pacific; it has been reported from almost all Polynesian island groups, but goes high up into mountainous areas all over its range.

Pantala flavescens (F.)

Material. — 23 &, 23 9, Rapa, Haurei, 11-28.IX, 3-31.X and 4.XII.1963.

Tropics and warmer temperate countries of the world; almost cosmopolitan, with strong migratory habits and probably also wind-carried.

N.B. — After the completion of this paper I received a letter from Mr. D. E. KIMMINS, of the British Museum (Nat. Hist.), in which he tells with regard to the Rapa Island Odonata, that the following species are represented in the collection: Ischnura aurora, Diplacodes bipunctata and Pantala flavescens. These were col- lected by Mr. COLLENETTE and Miss LONGFIELD during the “St. George” Expedi- tion and labelled as collected by the former. Being obviously common species, presumably only a single pair of each of these was taken.

Fig. 1. Ischnura thelmae spec. nov., Rapa I. Terminal segments of abdomen and appendages of & holotype, dorsal, left lateral and caudal view; posterior lobe of prothorax of © allotype, dorsal view

Dr. GATES CLARKE informs me that the species was generally found at fairly high elevations and believes that the immature stages will be found in the axils of the leaves of Freycinetia. This plant is abundant on the steep hillsides and occasion- ally overlaps into the flat areas along the ridges of Rapa.

Male (adult). — Labium pale yellow. Labrum, mandible-bases, genal area, anteclypeus, and vertical surface of frons greenish yellow, this colour extending upward along margin of compound eye to a level about half-way the distance between fronto-clypeal suture and median ocellus; basal one-third of labrum shiny

bronze-black, forming a transverse mark slightly produced forward in the middle. Postclypeus black with brilliant bronze-green reflex, its surface finely transversely wrinkled and sparsely clothed with long yellow hair, especially so along front margin. Posterior limit of pale frontal stripe very irregular, the area surrounding the antennal sockets remaining black; there is an additional black spot, shaped like a broad triangle, placed in the middle of the frons at its base. Antennal sockets yellow green in front, the first antennal segment finely ringed with yellow apically; rest of antennae black. Dorsal surface of head, including occipital ridge, bronze- black with metallic green and coppery reflections; occipital lobes tumid, produced backwards as an obtuse-angulate swelling on either side, dorsally with a pair of moderately large, completely isolated, subcircular, blue postocular spots. Rear of the head mat black with a very large, oval, greenish yellow area adjoining the eyes on either side.

Prothorax shaped and coloured much as described for I. taitensis; anterior lobe, lower parts of pleurae, and a streak along lateral margin of posterior lobe, greenish yellow. Posterior lobe short and broad, the transverse ridge-like lateral divisions raised on either side of the middle, where they are lowest and gradually become obsolete; median division swollen, placed on a slightly lower level and produced backward as a short rounded lamella. Lamina mesostigmalis transverse, subtrian- gular in outline, strongly hollowed out dorsally; colour black, except the swollen hind margin, which is yellow, terminating on either side in a conspicuously raised and recurved bluntly triangular tubercle.

Synthorax, ground colour light yellowish- to bluish-green, the dorsum and part of the sides bronze-black with metallic green lustre; pattern very similar to that of I. taitensis, the antehumeral stripes a little narrower and straighter, widest and more or less club-shaped at extreme base, their upper extremities hardly noticeably expanded; outer border of dark humeral band lacking an angular extension at the shoulder-area, but recurved upper streak and marginal lines along dorsal crests present; black stripe at second lateral suture complete, slightly irregular and variable in width, widest dorsally and more or less forked at the metinfraepisternal suture. Remaining parts of thorax and striped pattern of legs exactly as described for 1. taitensis.

Wings hyaline, neuration brown; 13—16 Px in fore wings, 11—13 in hind wings; 3 postquadrangular antenodal cells. There are two rows of cells between C and R, posterior to the pterostigma in one of the Rapa Maii Bay specimens, whereas in 5 others several cells are divided in one or more of the wings; lastly, in 4 males only a single cell-row is present. Arculus situated at Ax, more rarely a trifle beyond that level in all wings. Course of Cz, in fore wing straight as far as the end of first to second cell beyond level of subnodus, thereafter strongly fractured and reaching the wing margin at about Px,,; in hind wing this vein ends its unbroken course at level of Pxo, the fractured portion terminating at level of Px,, . Pterostigma not very different in shape and size in fore and hind wings, very oblique and distinctly higher than long in both pairs, this cell in fore wing differing from that of the hind wing only in that the outer distal angle is more drawn out, the anal side being, moreover, definitely outwardly convex. Colour of all pterostigmata dark brown surrounded by light chrome (possible bluish in life?),

94 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 4, 1966

heavily framed in dark brown; outer angle of fore wing pt including the inner margin of same more extensively pale-coloured than that of the hinder pair.

Abdomen shaped similarly to that of I. taitensis, the basal and terminal segments moderately expanded. Bronze-green markings of segm. 3—6 complete though less broad than those covering 1—2 and 7—10, widest basally and near apex of segments, where they are attached to complete, deep black apical rings; markings on the rest of the segments restricted to the dorsum, leaving not only narrow, transverse subinterrupted basal annules but also the whole of the sides chrome yellow. The complete dorsal marks of segm. 1—2 are shaped as in I. taitensis, the intersegmental annules being bright blue, as in that species. Terminal segments almost entirely black; latero-ventral border of tergites 8 and 9 narrowly striped with yellow, the intersegmental membranes of segm. 7—8, 8—9 and 9—10 like- wise pale. Apical portion of segm. 10 strongly pinched and in the form of a prominent dorso-apical tubercle, the hind border of which is whitish apically, as shown in the figure. The penis has the shape and armature characteristic for the genus, i.e., the second segment carries a pair of robust divergent, almost straight, backwardly directed black spines, one on each side of a bluntly raised median tubercle, the slightly recurved tips of the spines reaching the dome of the third segment; this latter terminates in two ribbon-like recurved processes, much longer than the spines, shaped similarly to those figured by FRASER (1927) for the Sa- moan ischnurine Amorphostigma auricolor Fraser.

Anal appendages shaped as in fig. 1, similar to those of J. taitensis but dif- fering in details of structure. Superior pair black, the lower part of the basal portion yellowish interiorly; surface shiny and clothed with the same longish hair as seen in /aitensis. In some males the dorsal angulation of the superior appendage, just before the bend, is better pronounced than in others, forming a blunt, back- wardly directed tooth-like projection, which is only poorly developed in the specimen figured.

Female (heterochromatic, orange colour form). — Labium pale yellow. Mouth- parts, face, and frons anteriorly, extensively orangish (between chamois and cin- namon, RIDGWAY). Black stripe at base of labrum ill-defined, acquiring soon a rusty brown tint and turning gradually to chrome beyond the median impression; postclypeus as in male, except that a transverse ferruginous spot is clearly discernible mid-basally. Dorsal surface of head orange with an irregularly shaped bronze-black band, widest in the middle, connecting the eyes across the vertex; the anterior border of this band is excavated on either side between median ocellus and antennal socket so as to save a prominent crown-shaped black dot placed immedi- ately in front of the median ocellus. Antennal sockets orange, the segments them- selves black. Epicranial lobes entirely orange, confluent with a transverse stripe at the occipital crest, this colour also occupying most of the occipital lobes ventrally, only the area surrounding the foramen remaining deep black.

Prothorax orange, save for a V-shaped black spot in the depression behind anterior lobe and a thick transverse bronze-black mark at the base of the posterior lobe, which itself is orange and shaped almost exactly as in the male (fig. 1). Lamina mesostigmalis less strongly concave dorsally than in male, the inner angle of its posterior rim not strongly protuberant but rounded and beset with a tuft of

M. A. LIEFTINCK : Odonota of Rapa 95

long yellow bristles which are directed straight upward; colour orange with a black dot filling up the inner anterior angle of the lamina.

Synthorax throughout orange, marked with a sharply delimited, parallel-sided bronze-black mid-dorsal band leaving the outer one-half of the mesepisterna un- covered. Antealar triangles, axillaries and notal sclerites orange; thoracic sides and ventral surface orange, but the former with a continuous black line at the humeral suture and a tiny black streak at upper end of second suture.

Legs light orange, but all spines black; vestigial black spots are present at the junction of the trochanters and femora and also at the apices of the latter; outer faces of anterior and middle tibiae with an obliterated black stripe, the extremities of all tibiae and tarsal segments likewise black.

Wings clear, neuration brown, lighter towards the bases; 14 Px in fore wing, 12 in hind wing. Pterostigma lozenge-shaped, greyish yellow, smoky grey in the centre; slightly less oblique and a trifle more expanded (longer) than in the male, shaped similarly in fore and hind wings; 1—3 duplicated cells between C and R, only in the hind wings.

Abdomen, ground-colour orange; dorsum of all segments (save the basal ones) marked more broadly with metallic greenish black than in the male and differing as follows: segm. 1—2 throughout orange, the intersegmental annule of 2—3 brown; 3 with the dark band narrower than those on the succeeding segments, tapering forward and not quite reaching base of segment; orange rings at base of segm. 4—7 slightly wider than in the male and not interrupted by black in the median line; terminal segments unmarked save for diffuse light spots low down at the sides of 9 and 10. Apex of 8th sternite abruptly constricted so as to form a short, tooth-like, black vulvar spine. Valves and anal appendages obscured, outer gonapophyses with a yellow stripe; styli black.

The second female is an old adult specimen which differs from the previous one by having the body much darker generally. All orange tints are replaced by light brownish olive, the postocular spots also being much obscured. Markings dull bronze brown to black, the basal stripe of labrum and entire postclypeus very shiny. Black stripe at humeral and second lateral sutures of thorax slightly wider than in the other female, the last-mentioned stripe linear but complete, extending along full length. Wing membrane greyish yellow, venation almost black. There are 14 Px in the fore wings, 13 in the hinder pair. Abdomen with indication of a dark sub-apical transverse marking placed on mid-dorsum of segm. 2.

Measurements: & abd. + app. 30.5—34.0 mm, hind wing 19.2—21.0 mm; Q 28.0—28.4 mm and 22.0 mm, respectively; most males measure 33 mm for the abdomen and 20 mm for the hind wing.

This interesting new species is chiefly remarkable for its large size, it being far superior in this respect to any other Old World member of the genus and even larger than the two described species of the allied Amorphostigma from Samoa. The male has the facies of a compactly built Teinobasis or Nesobasis, but the head is larger and all characters are decidedly those of a typical Ischnura. Apart from its dimensions, the male of I. thelmae is easily distinguished from its congeners by the bulging epicranial lobes, unmarked terminal segments of abdomen, as well

as by the shape of its anal appendages. In the last two characters it approaches I. taitensis Selys fairly closely, these two species being undoubtedly nearly related, taking an isolated position within the genus.

I have much pleasure in dedicating this dragonfly to its discoverer, Mrs. THELMA M. CLARKE.

Male (ad., Fautaua). — Labium pale ochreous, its median area glaucous. Labrum green with the basal one-third in the form of a sharply defined glossy black band which is slightly produced forward and obtuse-angulate medially. Mandible-bases, genae and anteclypeus bright green, the light area on the genae extending upwards along the eye-margin to a level almost as far as the median ocellus. Postclypeus shiny metallic greenish black, its surface rather convex, finely transversely wrinkled. Anterior surface of frons on each side of the middle with a two-pronged green mark directed obliquely inward, the branches of this spot divergent, narrow and tapered, the anterior branch a little longer than the posterior one and separated by black in the median line. Head otherwise deep bronze-black above with slight metallic green lustre; a tiny yellow dot in front of the median ocellus, and epicranium with a pair of large and conspicuous, bright blue, sub- triangular postocular spots, which are on all sides surrounded by black. Occipital crest unmarked. Rear of the head bicoloured: outer half of the surface bright blue, the inner half black with a comma-shaped dark off-shoot invading the blue colour towards the eye-margin. Antennae black, apex of first segment narrowly ringed with blue.

Prothorax predominantly bronze-black, anterior lobe bright blue finely bordered with black anteriorly; pronotal tubercles and most of the sides black, the former evenly convex; posterolateral portion of proepimerum including the lower proces- ses, green. Posterior lobe short, consisting of three portions: lateral divisions directed almost straight upward and separated from one another by a shallow emargination, the midlobe a little more swollen, placed on a slightly lower level and directed caudad; whole structure black, except the lateral divisions whose outer rims are bordered with green. Lamina mesostigmalis subtriangular in outline, dorsal surface of each strongly hollowed out with raised swollen margins which them- selves bear a bright green halter-shaped mark posteriorly.

Dorsum of synthorax, to a level about half-way between humeral and first lateral suture, deep black with slight metallic blue lustre; with a pair of complete, parallel, bright green antehumeral bands, which are distinctly widened, more or less club- shaped, on either end, extending almost as far as the ante-alar triangles at their upper extremities; mesepisternal dark colour irregularly bordered externally, encroaching on the blue of the thoracic sides to form a squarish extension upon the shoulder area and a short recurved streak invading the blue near the dorsal crest of the mesepisternum; mesinfraepisternum black with a triangular mark of blue-green adjoining the mesocoxa. Sides otherwise bright blue with a complete irregular black stripe on the second suture; this stripe widened (though also constricted) towards the dorsal crest; metinfraepisternum yellow-green outlined with black at the upper suture; ventral surface lemon yellow. All scutellar areas, wing processes and axillaries spotted with blue.

Legs bright ochreous green, the coxae each with a tiny dark basal spot and all femora heavily striped with black exteriorly; tibiae and tarsi dark ochreous, outer faces of anterior tibiae also with a continuous black stripe, but stripes along posterior two pairs of tibiae obliterated; the basal one-third of inner faces of tibiae likewise black; tarsal segments black-tipped.

Wings hyaline, neuration brown; 10 Px of first series in fore wing, 9 in hind

98 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 4, 1966

wing; 3 postquadrangular antenodal cells; arculus at or a little distal to Ax, in both pairs of wings; course of C#, straight as far as the end of the third or fourth cell following the quadrilateral in fore wings, of the fourth or fifth in the hind wings. Pterostigma dissimilar in shape and size in fore and hind wings, all very oblique; pt of fore wing about one-fourth longer than that of hind wing, sides strengthened and a little outbent in all wings. Fore wing pf two times longer than high, the proximal side only half the length of costal side and a little shorter than the distal one, which is more oblique; distal and anal sides forming a single convexity; costal side black but inner margin of distal side blue on upper surface; colour of cell jet-black dorsally for its proximal three-fifths, bright blue for the rest, with a yellow streak along costal margin; ventrally the cell is black save for a similar streak along costa. Hind wing pt only little longer than high, lozenge- shaped, almost parallel-sided; colour grey-brown on either surface and surrounded by a yellow line.

Abdomen of the usual shape and colour, marked broadly with bronze-black on the dorsum of all segments, the two basal ones rather more brilliant and more greenish black than the next; all markings a little expanded subapically and broadly attached to narrow black apical rings. Intersegmental membrane of segm. 1—2 bright blue, those of the intermediate segments obscured, and of 8—9 and 9—10 yellowish (possibly blue in life?). Segm. 3—7 have narrow clear yellow basal annules finely interrupted by black on mid-dorsum. Sides of segm. 1—2 blue, base of 3 blue-green, and of the remainder clear ochreous. Terminal segments unmarked, except laterally, the raised and excavated posterior border of segm. 10 yellow, as shown in the figure. Anal appendages shaped as in fig. 2; superior pair black, smooth and shiny interiorly, clothed with long pale pubescence above and within; inferior appendages a little longer and much more slender, their colour ochreous, save the outer border and apices, which are black.

Penis shaped similarly to that of I. thelmae (antea: 94), the backwardly directed black spines of the second segment are longer, the apices acute and rather abruptly downcurved; terminal processes of third segment shorter and narrower than in thelmae, evenly curved, about equal in length to the spines of second segment.

The above male corresponds in every respect with what has remained of the holotype, which is an incomplete specimen, quite immature, and lacking most of its abdominal segments. The 10th segment and left pair of anal appendages are, however, still intact in the type, whose characteristic face marks and enlarged post- ocular spots are still clearly shown.

The third male now before me, from Mt. Aorai, is far superior in size. It is a discoloured specimen, but as far as can be seen its markings are similar, except that the black lateral thoracic stripe is slightly wider; the blue antehumeral bands are, on the contrary, somewhat narrower than in the example described. The 10th segment and anal appendages are identical in shape, but the form of the ptero- stigmata in the Mt. Aorai male is rather different: in both pairs of wings it is shorter, only little longer than high in the fore wing and even slightly higher than long in the hind wing. It has also 11 instead of only 10 Px in fore wings, 9 in the hinder pair.

Female (isochromatic). — Labrum blue-green, the black basal stripe narrower

than in the male, occupying about one-fourth of whole depth of labrum. Mandible- bases and anteclypeus chrome yellow; genae light green, this colour extending upwards along the eye margin as far as the antennal sockets, which themselves are likewise green; postclypeus and a transverse crescent at the frontoclypeal suture, bronze-black; horizontal part of frons in the middle, as well as the rest of the dorsal surface posterior to it, bronze-black, with the exception of a light triangle in front of the median ocellus, a pair of very large subcircular postocular spots, and a greenish transverse stripe at the occipital crest.

Prothorax as in the male, except that each of the pronotal tubercles bears a green lateral spot, varying in size and shape. Posterior lobe shaped much as in the male, but lateral lobes less strongly upcurved, directed obliquely backwards and separated from one another only by a shallow emargination on a slightly lower level than the margins on either side of it; median division vestigial, not projecting caudad and visible only when viewed from behind (fig. 2). Light-coloured areas of thoracic segments bright blue-green, turning to green laterally and chrome yellow under- neath. Antehumeral stripes a little longer and wider than in the male, especially at either end, completely filling up the lower edges of the mesepisterna outwardly; bronze-black bands at the humeral and second lateral sutures narrower, the former with a linear extension along the dorsal crest.

Wings with 11 Px in fore wing, 9 in hinder pair; pterostigma of fore wing only about one and one-third larger than that of the hind wing, proximal and costal sides of equal length in both, but costal side in fore wing shorter than the anal and distal side more strongly convex than that of the hind wing; colour grey-brown surrounded by yellow.

Abdomen coloured and marked similarly to the male, the intersegmental mem- brane of segm. 1—2 blue, those of 7—8 and 8—9 yellow; vulvar spine short; appendages conical, obscured; valves light chrome, not surpassing apex of anal tubercles.

Measurements: & abd. + app. 21.0 mm, hind wing 13.2 mm (Fautaua), 26.7 and 16.0 mm (Mt. Aorai), respectively; 9 25.8—26.5, 17.7—19.0 mm.

Both male and female types are at present in a very dilapidated condition, various body parts having been repeatedly mended since the time of description. Owing to the juvenile state of the male and the loss of colour in either sex, these insects could have been defined hardly better; all the same, SELYS's original description is inevitably quite misleading. I. taitensis is, in fact, a brightly coloured insect, chiefly distinguished from other species by the following combination of characters: (1) exceptionally large size of blue postocular spots; (2) conspicuous blue-and-black pterostigma of male fore wing; (3) absence of colour marks on terminal segments of abdomen, and (4) shape of 10th abdominal segment and anal appendages of the male.

The discrepancies in size and details of the venation between the Mt. Aorai and Ape-Aotai specimens on the one hand, and the types (along with the male from Papeete) on the other, are worthy of note. These can probably be explained by the former having been taken at a much higher level than the latter. Ecotypic dif- ferentiation of forms with an extensive and fairly continuous vertical distribution is a common phenomenon also among dragonflies. Several examples are now

100 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 4, 1966

known of species in Java, Celebes and New Guinea ranging from the coastal | forests into the lower mountain zone, or even much higher, whose representative populations remain unchanged structurally but at higher elevations show a marked increase in size combined with an obscurated colour design and various deviations of the more ‘normal’ wing venation.

I. taitensis is obviously the same species as I. cheesmani Fraser in MUMFORD (1942: 646—647), described from a single male in the Royal Scottish Museum, Edinburgh. This came from Hitiaa, Tahiti, 10 July, 1925, L. E. CHEESMAN coll., and is stated by its describer to be “easily distinguished from I. taitensis Selys, by the presence of a lateral black stripe on thorax”; which is, in fact, exactly one of the characters of I. taitensis. For the rest, FRASER’s description is grossly super- ficial and his figures are worthless. All characters given for cheesmani in the description also apply to I. taitensis and hence there can be no doubt that the two are conspecific.

Still another endemic Ischnura from the Society Islands (Raiatea and Bora), apparently known only from two males in the British Museum, is I. cardinalis Kimmins (1929). Like I. aurora, the male is characterized by a variegated body pattern consisting of orange, blue and bronze-black; but I. cardinalis is superior in size and easily distinguished from other species by the blood red fore wing pterostigma and the great length of the inferior appendages of the male, the latter being over two times longer than the superior pair.

For many years I, and possibly other students with me, have been looking about for this remarkable species. If in the last decades it had been at all represented in the many collections brought home from the various island groups in the Pacific, it would surely have been recognized. Up to this time it has, however,

never been found again. With its nearest ally, the widely distributed I. aurora Brauer, the unique type of I. spinicauda is probably the fullest and best described member of the genus; for a general characterization the reader is, therefore, refer- red to the original description. A re-examination of the type reveals the following differences as compared with topotypical examples of I. aurora in our collection:

Spinicauda

Posterior lobe of prothorax trilobate, the edges of the lateral divisions evenly rounded and only slightly raised and thickened; upper portion of median division on level with the lateral ones and with a continuous pale border; triangular lower portion of median division (midlobe) project- ing caudad on a slightly lower level (ig, 3, left).

Abdomen, segm. 3—7 orange-red, scarcely and indistinctly obscured apically, 7 with bronze-black apical mark tapered to a point toward base and occupying terminal one-third or a little less of segment.

Bifid dorso-apical tubercle of segm. 10 more strongly raised, the tubercles closely approximated, arising from a marrow, rather pinched basal cone

(fig. 3).

Sup. anal app. in lateral view with its apex above more broadly rounded; outer branch of inf. app. longer, ending in a strongly upcurved finely pointed hook (fig. 3).

aurora (Tahiti)

Posterior lobe of prothorax trilobate, the edges of the lateral divisions more swollen and prominent but ridges gradually declining towards the middle and interrupted medially at a point where the surface is sunk; lower portion of median division similar to Spinicauda (fig. 3, right).

Abdomen, segm. 3—6 orange-red with finely black terminal rings, 6 with subapical bronze-black mark, variable in shape and size, usually attached to a black ring at apex of segment; segm. 7 wholly black.

Bifid dorso-apical tubercle of segm. 10 lower, the tubercles well separated from each other by a shallow emargin- ation.

Sup. anal app. in lateral view more elongate and narrowly rounded at apex above; outer branch of inf. app. thicker and more evenly upcurved.

102 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 4, 1966

As pointed out in BRAUER’s more elaborate description contained in the “Novara Expedition”, I. spinicauda can be distinguished from aurora, apart from the colour differences, by the more prominent process at the apex of the 10th segment and also by the shape of the appendages. BRAUER’s figures of the former are, however, not quite correct and rather exaggerated. I am, therefore, giving camera lucida drawings of these terminal structures taken from the type specimen, the origin and proper habitation of which still remain unknown.

NEW AND RARE PALAEARCTIC TINEIDAE (LEPIDOPTERA)

BY

IOSIE CAPUSE

Bucharest, Rumania

In the present paper which forms a continuation of my studies on the family Tineidae, descriptions are presented of a new genus, two new species and one new subspecies. Furthermore remarks are made on morphological characters of some other species not dealt with in the literature so far.

The systematic arrangement of the material is that proposed by G. PETERSEN.

The author wishes to express his thanks to Dr. A. DIAKONOFF, who kindly read the manuscript of the present paper.

NEMAPOGONINAE

Cephimallota libanotica Petersen, 1959 (Fig. 1)

Head orange-yellow. Antennae brown-yellow. First antennal joint nearly twice longer than broad, and four times longer than second joint. Labial palpi brown- yellow. Maxillary palpi somewhat longer than labial, yellowish. Galeae not sur- passing half length of labial palpi. Thorax grey-brown, tegulae concolorous, with a few lighter scales on posterior edge. Forewing without pattern, blackish brown, darker on the underside, posterior half lighter. Upper and under side of both wings with a faint violaceous gloss. Legs yellowish-brown with yellow bands on ends of tarsal joints.

In one of the specimens examined the colour and shape of the wings are asym- metrical: in the right forewing the apex is a little more truncate, while near it there is a rectangular spot, lighter than remainder of wing.

Male genitalia. Tegumen and vinculum forming a large ring. Vinculum with a rather long slender saccus. In dorsal view uncus with two cusps, reaching beyond posterior margin of valvae. A deep median excavation beset with numerous hairs. Arms of gnathos long-pointed. Valvae small, robust, densely haired. Anellus similar to that in C. simplicella (H.-S.).

TINEINAE

104 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 5, 1966 Tinea murariella Staudinger, 1859 | (Rio) |

Head yellow; antennae brown. Labial palpi blackish-brown with a few light scales. Thorax and tegulae blackish-brown. Forewing with a blackish-brown ground colour. Three spots darker than ground colour: two in basal third and one in. middle of wing. Hindwing grey-brown. Legs brown.

Male genitalia resembling those of T. /eonhardi Pet., but differing by stouter aedeagus, absence of small hair-like cornuti, and presence of spines on large cornuti. In T. murariella Stgr. distal end of the valva is strongly narrowed; aedeagus 2,7 X longer than valva. Tegumen, uncus, and gnathos normal.

Examined material. 1 4, Rumania, Ciungetu, 29.VII.1962 (D. DANCAU).

Distribution. Spain, southern France, Rumania.

According to PETERSEN (1959b : 569) T. murariella Stgr. is a western Mediter- ranean element while T. leonhardi Pet. is an eastern Mediterranean one. The occurrence of the species in Rumania proves that the actual range of T. murariella Stgr. is much wider than PETERSEN believed. Our present knowledge of the family Tineidae, however, does not allow of a delimitation of the geographical range of the species, many regions being insufficiently studied.

Tinea flavescentella Haworth, 1828 (Fig. 4—5)

Head yellow; base of antennae darker. Antennae light brown. Labial palpus yellow, externally and dorsally brown, its last joint dark brown with a lighter apex. Thorax yellow. Anterior half of tegulae brown, posterior yellow. Ground colour of forewing yellowish-brown. A dark brown spot on the base of costal edge. Marking similar to those in T. pellzonella L., consisting of two hardly visible spots in basal half of wing and a well-defined spot at 2/3 of wing length. Terminal part of forewing darker in colour. Hindwing greyish-yellow. Legs yellow.

Female genitalia. Sterigma medially with a strong concavity separating two lobes with short, hairy, rounded posterior edges. Ostium bursae strongly broadened. Bursa copulatrix, an elongate sack with three equal signa, each signum with a dilated base provided with one hair.

In PETERSEN’s revision (1957—1958) this species is characterized by the presence of four signa; the specimen examined by me has only three.

Examined material. 1 9, Rumania, Eforie Sud, Dobrogea Region, 30.VI.1962 (author).

Distribution. The species has been collected in England, Ireland, France, Germany, Italy, Yugoslavia (Dalmatia), Algeria, Turkey, and Rumania.

Monopis nonimella Zagulajev, 1955

This species is very similar externally to M. imella Hb. from which it can be distinguished only by the genital characters.

MEESSIINAE

Type-genus, Meessia Hofmann, 1898.

Head with long, slender antennae; usually both pairs of palpi well-developed; maxillary palpi absent in Lichenovora Pet. Second joint of labial palpus usually provided with variable number of rigid hairs. Wings elongate, lanceolate, with pointed apex. Markings of forewing in most species forming transverse bands or dots of diverse size and of a different colour, irregularly scattered.

In most genera of the subfamily there is a more or less marked reduction of venation. Thus in the forewing the whole length of the radial trunk or parts of it are feebly marked (e.g., Ischnoscia, Lichenovora, Lichenotinea, Phereoeca, etc.). In some genera (Ischnoscia, Obesoceras) R and Rg, and in other (Infurcitinea, Gozmanytinea, Lichenotinea, Meessia), R, and R, are pedunculate. Sometimes R; (Lichenovora) or one of the median veins (Obesoceras, Ischnoscia) are missing. Veins A, (Agnathosia, Lichenotinea, Ischnoscia, Obesoceras, Infurcitinea, Goz- manytinea) and A, (Celestica) can be missing or weakly marked. Radiocubital cell, narrow and very elongate, is sometimes open (Lichenovora, Phereoeca).

The radial trunk in the hindwing is sometimes feebly marked or absent (Lichenovora, Lichenotinea, Infurcitinea, Phereoeca, Celestica); in some genera there are three median veins (Lichenotinea, Infurcitinea, Gozmanytinea, Licheno- vora, Phereoeca), while in other there are only two (Celestica, Ischnoscia, Obeso- ceras, Meessia). In some genera the anal veins, generally feebly developed are present as a single vein (Infurcitinea, Gozmanytinea, Meessia), or as two veins (Lichenovora, Obesoceras, Phereoeca) or they may be missing (Celestica, Isch- noscia, Lichenotinea). The radiocubital cell in the hindwing is as a rule elongate and closed, at times open (Lichenovora, Celestica, Lichenotinea), seldom short and narrow (Ischnoscia). In some instances it includes the radial trunk (Obesoceras, Meessia).

Median spurs of hind tibiae on basal half more or less close to base.

For the genera of this subfamily only descriptions of the venation are given in the following pages; these data have either been spread in a number of separate publications or not described at all; the male genitalia, on the contrary, have been very well characterized by PETERSEN (1957—1964).

The male genitalia are characterized by more or less pronounced reduction of the uncus and gnathos, which in some instances can be missing altogether. Valvae developed, strongly specialized, sometimes asymmetrical (Infurcitinea). Vinculum strongly developed, very broad in some genera (Lichenovora, Lichenotinea) while in other it is narrow and has two tips (Infzrcitinea), or a saccus of variable length and breadth (Celestica, Agnathosia, Phereoeca, Montetinea, Meessta, Obesoceras, Gozmanytinea, Ischnoscia, Novotinea). Aedeagus developed, usually with cornuti; in some genera the shape of aedeagus is very characteristic. Sometimes, e.g. in Infurcitinea, the anellus is strongly developed.

I. CAPUSE : Palaearctic Tineidae 107

Since the female genitalia are known only in few members of this subfamily, it is not possible to characterize them at the present time.

The scanty data in the literature show that the larvae of the subfamily Meessiinae feed on lichens, and that the adults may be captured on rocks covered with lichens and at night at light.

The present subfamily includes the following genera: Celestica Meyrick, Agna- thosia Amsel, Phereoeca Hinton & Bradley, Montetinea Petersen, Meessia Hof- mann, Obesoceras Petersen, Gozmanytinea gen. nov., Infurcitinea Spuler, Tiner- forma Amsel, Lichenotinea Petersen, Ischnoscia Meyrick, and Novotinea Amsel.

Celestica Meyrick, 1917 (Fig. 6—7)

Type-species, Tinea angustipennis H.-S., 1854.

Until now this genus stands isolated within the family Tineidae, showing affinities with some Meessiinae.

Wings very elongate and narrow. Sc of forewing terminating before middle of wing; radial veins all from the radiocubital cell. The distance between R, and R, about twelve times larger than that between R, and R;. The three median veins are present and well marked. Cubital trunk strong; cubital veins missing. One anal vein present, distinct throughout. Radiocubital cell very elongate, exceeding 2/3 of wing length, very narrow basally.

Sc of hindwing terminating beyond marginal half of costa. Basal half of radial trunk not evident. R well marked. Two median veins present. Cubital trunk curved and close to anal edge of wing. Cu, and Cu, present, short. All anal veins missing.

Only one species.

Examined material. 1 3, Poland, Oswiecim, 30.VII.1960 (S. TOLL) (C. an- gustipennis).

Distribution. Yugoslavia (Macedonia), Rumania, Central Europe, Netherlands, Denmark, Finland, England.

Agnathosia Amsel, 1954 (Fig. 8—9)

Type-species: Tinea mendicella Hübner, 1796.

Vein Sc of forewing terminating on costa before middle. Radial trunk feebly marked. All five radial veins independently ending on costal edge of wing. Distance between bases of veins R, and R, about 3.5 X as large as that between bases of veins R and Rg. Veins Ry, R;, M, and M, weak along a short distance from base. Three median veins. Cubital trunk and two cubital veins well marked. A, feebly marked, not reaching edge of wing, A, strongly marked, reaching that edge; A3 absent.

Costal edge of hindwing with a convexity; Sc terminating beyond half of wing. Radial trunk feebly marked and radial vein with a weak small portion from base, remaining part strong. Bases of M, and M, close together. Cubital trunk and cubital veins well marked. Only one anal vein apparent, but weak, reaching to edge of wing.

by a well-sclerotized, relatively long colliculum. Beyond this the membraneous ductus is strongly extended, then narrowed before bursa copulatrix. A dentate, sclerotized plate at the beginning of ductus bursae. Corpus bursae relatively small, oval, with an agglomeration of spinules in median portion dorsally.

M. herculanella resembles in external appearence M. vinculella (H.-S.) from which it differs by the darker ground colour, the lack of golden gloss and by less extended but more pronounced pattern. With the aid of genital characters M. her- culanella is easily recognizable by the presence of signa, dentate sclerite, and spines of corpus bursae. The venation of the forewing resembles that in M. vinculella (H.-S.) (SPULER, 1910), only the stalk of R, and R; is much longer.

Obesoceras Petersen, 1957 (Fig. 19—28)

Type-species, Tinea granulatella H.-S., 1850.

Forewing with additional vein present, fused with Sc, ending before middle of costa. All radial veins present; R, and R, stalked. Base of R, usually close to base of R;. Sometimes M, from common stalk with R; (O. confusellum orientale, O. hedemanni). Sometimes one of the median veins absent (O. granulatellum, O. hedemanni). A, does not reach margin and is weak. United portion of A, and As long; small portion of these veins free at base. Radiocubital cell narrow and long.

Hindwing with vein Sc to near middle of costa. Radial trunk weak, forming a very narrow long cell together with median trunk. R, M, and M, from end of cell. M; absent. Cubital trunk distally furcate; terminal portions of cubital veins weak. Two anal veins.

The genus includes the following species: O. granulatellum (H.-S.), O. holtzi (Rbl.), O. confusellum (H.-S.), O. hedemanni (Rbl.), O. croaticum Pet., O. romanum Pet., and O. forsteri Pet.

Obesoceras granulatellum (Herrich-Schäffer, 1850) (Fig. 19—20)

Head brown-yellow. Antennae brown-black. Forewing black-brown with yellowish-white costal spots at 1/3 and 2/3, respectively; towards dorsum each spot continued as two narrow bands. A small line and two yellowish-white spots in apical area. Hindwing dark brown.

Venation of forewing similar to that in O. confusellum orientale subspec. nov., from which it only differs by the lack of median vein and by distant bases of R4 and R;.

Ostium bursae large, surrounding area weakly sclerotized. Ductus bursae narrow at base then strongly dilated. Bursa copulatrix elongate with ten sclerotized signa, shaped as slender dentate rods. Apophyses anteriores furcate, dorsal arm longer than ventral, and with two apical hairs.

Head yellowish-white; a few brown scales on frontal margin. First antennal joint brown-black, remaining joints yellowish-white with distal narrow brown rings. Labial palpi dirty white; 2nd and 3rd joints distally brown. Forewing with brown- black ground colour, markings, white bands and spots. Oblique transverse band from dorsum near base to half of wing breadth. Small square spot on 1/4 of costa continued towards dorsum by three interrupted lines. On middle of costa small rectangular spot continued a little obliquely across wing; two interrupted lines from lateral angles of the spot. In the apical half of wing three narrow, transverse bands obliquely to base of wing. Hindwing blackish-brown.

After a long free portion, Sc of forewing anastomosing with additional vein to before middle of costa. Radial trunk weak, stronger only between bases of R, and stalk of R, | 3. R, approximately to middle of costa. R; and M, forming a long stalk, originating close to Ry. R, terminates at costa about twice as far from apex as M, is at termen. M, and My present. A, weak, not reaching dorsum. A, and A, well marked, free at base, their anastomose twice as long as free parts.

Legs brown with yellowish-white spurs and yellowish-white ringed tarsal joints.

Male genitalia. Tegumen + uncus broad with lateral edges turned inward. Top of uncus bilobed. Vinculum broad, with thick and relatively short saccus. Gnathos unpaired, with curved, dilated and short-spinose apex. Lateral lobes of tegumen short and relatively broad with much narrowed end. Cucullus narrowed, finger- shaped. A strong tooth near middle of ventral margin of valva; dorsal margin hardly concave in middle. Sacculus, a large conical prominence, the margin of which beset with numerous strong short spines. Aedeagus short and thick with a narrowed strongly sclerotized apical portion. One short, dentoid cornutus present.

Female unknown.

O. confusellum orientale subspec. nov. is very similar to O. confusellum con- fusellum (H.-S.); however, as the descriptions and drawings of PETERSEN show, there are some distinct differences. Thus externally O. c. orientale subspec. nov. differs from O. c. confusellum (H.-S.) by having two well-defined costal spots, continued to dorsum as two or three lines and having three stripes towards apex, instead of two indefinite median stripes and one apical spot. Moreover, the ground colour is darker in O. confusellum orientale. It is apparent from PETERSEN’s key, descriptions, and drawings that in O. confusellum (H.-S.) the uncus is not bilobed, as in our subspecies. In O. c. orientale the dorsal margin of the valva is more straight while in O. c. confusellum it is concave. In the new subspecies the cornutus is situated in the narrowed portion of the aedeagus (in O. c. confusellum, in the distal end of the vesica).

with costa rounded-prominent; Sc to beyond middle. R free from cell, its basal half weak. Median trunk weak. M, and M, curved downwards. Cubital veins relatively long. Cubital trunk strong. Only distal end of anal vein defined. Anal field broad.

The male genitalia are charactized by the symmetry of all the parts. Tegumen + uncus long, relatively narrow with lateral edges turned inwardly. Vinculum broad, with a single tip. Valvae basally broad, narrowing apically, narrowed portion with numerous basad directed hairs. Near the base of the costa there is a process which can be short (G. banatica), or long (G. captans) or furcate (G. albanica, G. kasyi, and G. litochorella). Aedeagus rather short, straight, with a small dilatation basally, broadened distally, usually with two small tips. Anellus cuff- shaped, membraneous, with minute dentations, without sclerotized projections or hairy arms, as in Infurcitinea Spuler.

The female genitalia are known in a few members of the genus only (G. cap- tans and G. banatica).

Gozmanytinea gen. nov. is very similar to Infurcitinea Spuler, having a similar venation. Our genus differs from the latter chiefly by the characters of the genitalia; in Gozmanytinea the genitalia are symmetrical, in Infurcitinea, asymmetrical; the vinculum in the new genus has a single tip, instead of two as in Infurcitinea; the anellus is in the shape of a membraneous denticulate cuff, without projections, while in Infurcitinea this part bears projections or hairy arms.

Althought the venation is not differing from that in Infurcitinea and only slightly differing from that in Lichenotinea, I consider the group of species assigned to Gozmanytinea to represent a distinct unit showing a separate line of evolution, judging from the genital characters.

I have assigned the following species to Gozmanytinea: G. captans (Gozm.), G. banatica (Pet.), G. albanica (Pet.), G. kasyi (Pet.), and G. litochorella (Pet.).

tered points. Fringes white. Venation as in the genus. Hindwing brown-grey; fringes dirty white.

Male genitalia. Tegumen + uncus relatively broad, slightly narrowing towards end. Vinculum narrow with two rather long processes. Valvae very broad at base, strongly narrowed towards apex, asymmetrical. Left valva with two rather long, slender, club-like arms, ventral somewhat shorter, dorsal with strong, rigid hairs. Bases of these arms with oblique, transverse, sclerotized ridges with distal edges slightly concave. Right valva more abruptly narrowed with short apical processes; dorsal margin of narrowed portion with strong rigid hairs; internal surface at the narrow part with a bilobed ridge, longer than in left valva, obliquely longitudinal. Bases of valvae ventrally covered with dense hairs. Anellus shaped as a plate with a strong constriction beyond a broad base; it is dilated again from middle, tapering apically. Aedeagus slender and narrow, strongly dilated at base, divided before middle in a straight, pointed arm and a curved, longer arm, covered with dense broad spines.

Female genitalia. Eighth segment ventrally with a sclerotized tube, dilated distally, upon which lays the ostium; dorsally with a sclerotized triangular body haired apically. Apophyses anteriores rather short with furcate posterior parts, arms dorsally united. Apophyses posteriores long. Anal papillae haired.

I. romanica spec. nov. resembles I. olympica Pet. but differs both externally and internally. In the former the first antennal joint is yellowish-white, in the latter brown-white. The labial palpi in romanica are black-brown externally, in o/ympica only the base of the third joint is brown. The black-brown dots of the forewing are more numerous in olympica than in romanica.

NOTES ON SOME ANTHOPHORINE BEES, MAINLY FROM THE OLD WORLD (APOIDEA)

BY

M. A. LIEFTINCK Rijksmuseum van Natuurlijke Historie, Leiden

Abstract

An outline is given of the present state of our knowledge of the tribe Anthophorini. This is followed by a discussion of the status, interrelationship and distribution of some Old and New World components of the Habropoda association. The essential features of the type- species of Anthophora, Emphoropsis, Habropoda and Elaphropoda are enumerated and, to ensure generic and specific recognition, illustrations of the more important male characters are supplied for each of these. A review of the Old World members of Habropoda includes Anthophora oraniensis Lep., from Algeria, which is redescribed and figured. Species doubt- fully referred to Habropoda are listed, but it is emphasized that this taxon can be split up in a number of distinct genera with broadly overlapping ranges. One of these is Elaphropoda, a new genus from Eurasia, which contains several already described and one new species, E. bembidion sp. n., from Borneo.

Introduction

The Anthophoridae are a large group of solitary bees having an almost world- wide distribution, a great many of which also occur in the tropical parts of the Old World. As far as the elements of the tribe Anthophorini are concerned, those of the Ethiopian and Malagasy faunal regions are still imperfectly analysed and will not concern us here: in addition to some others also found elsewhere, two genera, Pachymelus F. Smith, 1879, and Pachymelopsis Ckll., 1905, are richly

represented in Madagascar and apparently peculiar to that island. In Eurasia and Australia, on the other hand, six non-parasitic genera of the tribe have so far been recognized. These are: Anthophora Latr., 1803 (including the poorly defined Paramegilla Friese), Heliophila Klug, 1807, Habropoda F. Smith, 1854, Clisodon Patton, 1879, Amegilla Friese, 1897, and Asaropoda Cockerell, 1926. In the present paper only Habropoda and a new taxon closely related to it will be discussed in somewhat greater detail.

The genera Anthophora, Heliophila and Clisodon 1), having mainly a Palearctic and Mediterranean distribution in the Old World, are not or only poorly

represented in southeast Asia and are absent from Australia. Amegilla, with its numerous species throughout the warmer parts of the Eastern Hemisphere, is also the dominant genus in southeast Asia and the Australian region. It was briefly reviewed by Popov (1950), who was the first to firmly establish its status within the family, supplying at the same time a list of the described species and lower categories compiled from the literature then available to him. Towards the eastern periphery of the Oriental region and on the mainland of Australia Amegilla mixes with species of the nearly related Asaropoda, which has its centre of distribution in Australia. A synopsis of the Australian forms was published by RAYMENT (1951), whose treatment is, however, superficial and does not include any of the taxa defined by earlier writers. Lastly, the origin and geographical distribution of the Eurasian genus Habropoda were discussed at some length by Popov (1948), whose paper clearly demonstrates the complexity of this group. In this synoptic review the author outlined the supposed evolutionary history of these bees, refer- ring simultaneously to some taxonomic features. It was necessarily based on a study of the genus in its broadest sense, as it comprised all described Old World forms previously assigned to it. Although many of the latter were known to him only from the literature, all recorded localities were treated alike and entered in a map showing the distribution regardless of group differentiations. Popov’s concept of Habropoda not only necessitated the inclusion of at least one African element of rather remote affinity but also of other units with which he was not personally acquainted. As a matter of fact, three Eurasian genera with overlapping ranges are involved in Popov's account. Two of them are treated in the present paper, while a third (and probably more) still require careful analysis. Moreover, these taxa are morphologically as closely related among themselves as each of them can be linked with the dominant genus Anthophora, which is itself highly polymorphic and of widespread occurrence. For some unknown reason the last-mentioned genus was entirely left out of consideration in Popov’s account. We have at present obtained a somewhat better knowledge of the morphology of these bees and, though still far from complete, it indicates that Popov’s interpretation of the present-day distribution of the Habropoda group requires considerable alteration. I also think that the conclusions arrived at by him, though admittedly tentative, are rather premature and do not permit of a decisive answer to be given on the origin and evolution of these bees.

In a publication that appeared four years in advance of Popov’s review but which for obvious reasons had remained unknown to him, I have given characterizations of a number of old and new species of “Anthophora’ and “Habropoda’ occurring in the Malaysian subregion (LIEFTINCK, 1944). All regional species previously assigned by me to Anthophora were subsequently transferred to Amegilla (LIEFTINCK, 1956) but, in anticipation of a thorough analysis of the whole complex still amalgamated in Anthophora, I merely stated that a new genus would be necessary to accommodate the tropical oriental bees formerly included in Habropoda.

It is the object of the present paper to demonstrate the principal features of this compact little group, which is here introduced under the new name Elaphropoda, gen. nov. An attempt will be made to directly compare the type-species and allied

M. A. LIEFTINCK : Notes on Anthophorine bees 129

forms of this taxon with others of more remote affinity and with the types of three other genera considered to be most nearly related. These representative species are: Anthophora acervorum (L., 1758), Emphoropsis kboriosa (F., 1804), Habropoda tarsata (Spinola, 1838) with its immediate allies.

The principal generic characters of Anthophora are contained in the well-known publication of MICHENER (1944), while definitions of Emphoropsis have been supplied by a number of writers whose publications are cited under that genus.

The illustrations of morphological structures accompanying the text of the fol- lowing account are intended to be self-explanatory. As far as the genera Antho- phora and Emphoropsis are concerned, the figures are given solely for the purpose of comparison with corresponding structures found in Habropoda and Elaphro- poda, more comprehensive notes and descriptions, where necessary, being supplied only for the latter.

Anthophora Latreille, 1803

As is well known, Anthophora contains an enormous number of very diverse species distributed all over the temperate and subtropical parts of the world, with radiations in more southerly directions. There is, in fact, a marked decrease in the number of species south of the Tropic of Cancer; and when leaving aside the Anthophorini of the African fauna and South America, whose components and affinities are still imperfectly studied, it can be said that in the Old World tropics no true Anthophora occur in the Malay Archipelago nor has any been found in the Australian Region or the Pacific islands.The greatest diversity in morphological features exists amongst those inhabiting the temperate regions of the Old World from which it may possibly be inferred that the Nearctic elements are derived from old stock centred in the Palearctic Region.

In the existing keys and descriptions of these Old World Abo group characters that may express the probable relationships have only rarely been taken into account 1). Of the great majority of Mediterranean and Asiatic species, for instance, practically no descriptions or figures exist of the head and leg structures or of the male copulatory organs, so that many remain unrecognizable. In several instances it is not even known whether such forms are true Anthophora or Ame- gilla. Some of the former are superficially much like Amegilla while others may easily be mistaken for Heliophila, which themselves are sometimes astoundingly similar to certain Amegilla with which they occur together. The highly specialized short-haired and banded groups of true Anthophora are thus frequently confused with similarly-looking sections of allied genera. With so many of them only known from descriptions, it is hardly surprising that generic identification can only be a matter of guess-work. A notable exception to the rule forms the beautifully

1) A section still of doubtful generic (or subgeneric) status is the “subgenus” Paramegilla Friese, 1897. According to FRIESE, the only character by which it is said to differ from Anthophora is the presence of large, white pubescent spots at the sides of the abdominal segments. The type-species of Paramegilla is Apis ireos Pallas, 1773, from Russia; I have only seen a female of another included species, A. (P.) christofi F. Mor., 1880, from Turkestan.

illustrated work of MoRAWITZ (1875) on the bees of Turkestan. In this out- standing publication a number of excellent drawings of male genitalia are found which are most helpful in segregating the regional genera and species groups.

The most comprehensive study of Anthophora is the one published by MICHE- NER (1944), who provided a profusely illustrated account of the general morpho- logy and anatomy based on one of the commonest Nearctic species, viz. A. edward sii Cresson. For comparison with other genera discussed in the present paper I have, for similar reasons, selected one of the best known European representatives,

Always excepting the differences found in the wing venation, generic characters applicable to both sexes of Habropoda are not very well marked and (for the female) difficult to evaluate. The main characteristics are contained in the afore- cited references, but it should be remembered that in the diagnoses given by Dours, PATTON, BINGHAM and also Popov, members of the allied genera Emphoropsis and Elaphropoda were included. The best general definitions are those supplied by SMITH and DE SAUSSURE, insofar as these are based only upon the Mediterranean forms. I have failed to discover clear-cut characters for the female other than those found in the venation, for I have observed that some features of the mouth-parts, legs and pygidial area are hardly, if at all, different from those of certain large-sized species of Anthophora. In both sexes of the more typical species of Habropoda the interocellar distance is only little longer than the ocellocular distance, whereas in the type-species of Emphoropsis the lateral ocelli are more widely separated (ratio about 10 : 7); lastly, in two Emphoropsis-like bees (from Vietnam and Fukien, respectively), the reverse condition exists (ratio 8.5 : 10). These differences may be, however, of specific rather than generic

significance. Males are easily recognized by a combination of sexual characters, primary as well as secondary; most of these will be apparent from the accompany- ing figures. An additional feature worth mentioning is, perhaps, the attenuated and curiously flattened flagellar segments of the antennae, which in all males extend beyond the tegulae.

Popov (1948) has already called attention to the remarkably elaborate form and texture of the invaginated seventh and eighth abdominal sternites in Habro- poda males. Somewhat beyond half-way their length these plates are distended, bearing transverse and swollen ridges with angulate or tooth-like marginal projections which are heavily sclerotized; the apical portions often bear strong

papillae and bristle-like setae (see fig. 49, 57—58, 63—64, and 69—70). The long apodemes and spiculae of these plates are also present in some Emphoropsis and Elaphropoda but the ridges and processes in Emphoropsis are only poorly indicated while they have completely disappeared in the highly specialized Elaphropoda.

It will be seen from our illustrations that the resemblance between Habropoda

M. A. LIEFTINCK : Notes on Anthophorine bees 135

and Anthophora is not quite as great as that between either of these and Empho- ropsis, the latter taking rather an intermediate position in almost every respect.

Pending a characterization of the species reportedly known from the African continent (south of the Sahara), it seems best not to include these in Habropoda in the strict sence as applied here. I do not know which species from South and East Africa Popov (1948) had in mind when recording these on a map (loc. cit.: 1674). He remarks upon four but, with the exception of H. festiva Dours (from

Fig. 53. Genital armature of Elaphropoda impatiens (Lieft.), Bukit Kutu, Malaya. Fig. 54, the same of Habropoda tarsata (Spin.), Rome, Italy. Enlarged on the same scale

“Cafrerie”), none of them was mentioned by name. I have examined and dissected a male of a species apparently closely allied to festiva from Tanganyika but, although this shows some approach towards Habropoda, it is surely not congeneric, differing also in the venation.

Following the specific accounts of Habropoda proper, I have appended a list of the Asiatic forms questionably referred to it by previous authors. This list may or may not include a remarkable species from China of which I have dissected a male from Fukien, which undoubtedly belongs to yet another genus; it resembles Elaphropoda but is wholly different structurally. I hope to deal with this and other forms in a future paper.

136 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

Lastly, mention should be made of Anthophora gracilipes F. Mor., 1873, from the Caucasus. This is one of a separate species-group of Anthophora, which in 1877 was erroneously transferred to Habropoda by RADOSZKOWSKI (Horae Soc. Ent. Ross. 12 : 334); I have seen both sexes of it.

Distribution. — From the Mediterranean region eastwards through central Asia to China (Peking).

Remarks. — The species of Habropoda are probably parasitized by the conspicu- ous velvet black-and-white pubescent bees of the melectine genus Eupavlovskia Popov, whose distribution corresponds very nearly with that of their probable hosts with which they were repeatedly found associated in the field. Nothing further seems to be known of their biology.

Material. — 1 & 1 @ (paratypes), labelled (in Russian) “Village Kwak, 2000 m, 35 km N of Dushanbe, 10 & 20.VI.1937, V. Gussakovski” and “Ha- bropoda tadzhica sp. nov. Popov’, det. V. Popov 1947, in Mus. Leningrad.

This species comes nearest H. tarsata. The original description is incomplete and does not do full justice to the nature of the pubescent body pattern and the peculiar structure of the legs and terminalia of the male. The abdomen is neither tricoloured (tarsata) nor banded (zonatula), but uniformly clothed with rather long and dense golden yellow hair. The bright yellow clypeus of the male is marked with black as in the species just mentioned, the size of the spots being intermediate between the two. Like H. tarsata the fore legs are of simple structure but the long spine-like coxal process is reduced to a short plate-shaped lamella. Femur and tibia III are greatly swollen, the inner carina of the tibia terminating in a short tooth-like subapical projection; the smooth and shiny inner surface of the greatly modified basitarsus (fig. 55) is deeply hollowed out, the whole structure smaller than in farsata and shaped differently. The 7th and 8th sternal plates are shown (fig. 57-58), the 8th sternite bearing more likeness to that of tarsata (fig. 50) than to zonatula (fig. 64), and considering also the structure of the genital capsule with its appendages (fig. 56), tadzhica appears to be most closely related to tarsata. This resemblance applies also to the female pygidial plate, which in the latter is more narrowly triangular and pointed than it is in zonatula and allies.

but the abdominal pubescence covers most of the exposed tergal surface and the anterior limit of the dense apical banding is effaced by the presence of much shorter and scantier pale hairs covering the basal portions of tergites 2—4. There is also a greater abundance of longish erect hair interspersed between the appressed pubescence and this has led Popov to associate this species with H. tarsata rather than ezonata and immediate allies. His view is supported by the pygidial plate of moesta being more convex and more definitely pointed than in ezonata. It is, in fact, shaped similarly to that of tadzhica and tarsata, the last two being un- questionably intimately allied species.

Superficially, the female of this conspicuous banded bee is more like Antho- phora or some large-sized Amegilla than any of its congeners. From the former it can be distinguished, apart from the neural characters, by the narrow malar space and the widely distant lateral ocelli; from Amegilla it differs by the presence of pulvilli between the tarsal claws and other characters. The face-marks and morphological details of a male from Greece are here shown in fig. 59—64.

Distribution. — Like H. tarsata a spring species, first described from Albania. Widely spread and, though apparently very local, showing a distribution that broadly overlaps the range of tarsata. The localities known to the writer are as follows. France: Hyéres (Var). — Italy: environs of Rome (Lazio); Brindisi (Apulia); Sicily: Mt. Etna (Mte. Rossi, 800 m) and Taormina (Mte.

Amanus Mts. (Gavur Daglari). — Azerbeidshan (Caucasus): Bacu. — Transcaucasus: various localities. — According to Mr. E. STANEK (in litt.), the species has recently been discovered also in Czechoslovakia. Remarks. — There is an old record by FRIESE (1897 : 55) who found the bees in Hungary, nesting in loamy soil on the roadside between Rakos-Kereshtur and Czinkota (east of Budapest). The same author mentions Melecta funeraria (= Eupavlovskia funeraria (F. Smith) as its parasite. Flower records for the female in Hungary are Salvia and Vicia (FRIESE, 1897 and Moczar, 1958); IUGA (1955) observed that in Romania males frequent the flowers of Robinia pseudacacia.

Lectotype @ (by present designation), labelled “Oran” on blue disk, under drawer label “Anthophora Oraniensis Q” (LEPELETIER’s writing in red); lectoallotype ¢ (by present designation), dissected, bearing same labels as lectotype 9 ; 1 4 1 ©, unlabelled.

The above specimens quite unsuspectedly turn out to be true Habropoda, constituting a species that has always been looked upon as a member of Antho- phora. It has been no easy matter to find out whether LEPELETIER’s bee has any- thing to do with the Anthophora oraniensis of Dours (1869), Lucas (1849), FRIESE (1897) or PRIESNER (1957 : 79—80). FRIESE placed it in a separate group of his “Subgenus Amegilla Friese’, together with A. caroli Pérez (which is an Anthophora) and fulvodimidiatus (Dours) (which is a Heliophila); what he thought to be a female of oraniensis in all probability is some species of Ame- gilla. The other authors referred to it as Anthophora but in no case did they supply enough details to enable its recognition. Even the beautifully executed colour pictures and line drawings in Lucas's work give no clue to reveal its identity, so that it still remains possible that here also some similarly-looking species of Anthophora was mistaken for it.

H. oraniensis resembles H. zonatula Smith very closely in most respects. The following additional descriptions may be supplied of the two sexes, one each (out of only five) being still in perfect condition.

Female (lectotype, Oran). — Stature and pubescent pattern as in H. zonatula. Vestiture of head silvery white, very dense and decumbent on labrum, gradually acquiring a yellowish white tint on vertex and becoming fox red on temples, occipital region, thorax and first gastral segment; this bright colour changes to brown on the lower portions of the thoracic pleurae. Legs for the greater part black haired; tibiae I and II outwardly with a streak of depressed silvery white tomentum, the black covering inner faces of femora I and II interspersed with pale hairs; outer faces of basitarsi II whitish. Tibia III black, but outwardly with

surface; pygidial segment black. Ventral surface of gaster mainly dark in the centre, densely fringed with whitish laterally; apical pubescent band of tergite 4 broadly continuous underneath so as to cover also the sternal surface, the next segments also clothed with long white hair.

Male (lectoallotype). — General aspect, size and texture almost as in H. zona- tula; differs from it in the reduced face marks, more brightly coloured pubescence and in structural details of legs and terminalia.

Antennal segments 4—13 missing. Legs generally slightly more robust, pro- coxal process very similar but more evenly and less strongly downcurved; shape of basitarsus I similar to zonatula, but basitarsus III relatively shorter and more expanded distally, the apical process thicker and bluntly triangular, not lanceolate as in zonatula (cf. fig. 60 and 66). Clypeus yellow, with indication only of dark basal markings (cf. fig. 59 and 65). Pubescent pattern much as described for the female, brighter than in zonatula; decumbent and white on labrum, changing to yellowish white on clypeus and brightening to orange on vertex; vivid thoracic pubescence becoming lighter, almost white, laterally. Legs clothed with silvery white tomentum. Transverse apical bands of gastral tergites 2—5 distinct, but on 6 only the sides are white-haired; ventral surface of 3—5 clothed with white hair laterally.

The contour and sclerotization of the 6th gastral tergite and exposed sternal plates are very nearly identical in the two species compared, but contrasting characters are found in the shape of the apical portions of the seventh and eighth sternites, the surface and borders of which are more or less profusely adorned with papillae, thick sensory(?) setae and fine pubescence, variable in size, arrangement and density, as shown (cf. fig. 63—64 and 69—70). When comparing the genital armature of oraniensis with that of zonatula, it will be observed that slight but well-marked differences also exist in the shape and vestiture of the gonocoxite, whose two branches (gonostyli) are shown in outer and inner aspect (cf. fig. 61—62 and 67—68).

LEPELETIER's cotypes ( 4 and 9 in Mus. Paris and 4 in Mus. Torino) are badly damaged and partly eaten away by insect pests, but all specimens are un- doubtedly conspecific.

The female of this bee is so much like H. zonatula in general appearance and vestiture that it can be easily mistaken for it. The description of the leg structure

144 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

of the male 1) also corresponds with zonatula but, since it belongs to a group of closely similar species even in respect of the male terminalia, I have no hesit- ation in following Popov and considering it a distinct species. Males are not available for comparison but in the female of balassogloi the pubescent abdominal bands are distinctly broader than in zonatula and the marginal hair fringes at the apical sternites are longer, denser and white instead of yellow, the long pubescence at the temples, thoracic sides and on the scopa being also silvery. Apical hair band of gastral tergite 5 palest silvery yellow sparsely intermixed with light brown and hair on both sides of pygidial plate light brown (all bright fer- ruginous in zonatula). Pubescence on inner faces of middle and hind basitarsi and penicillus dark brown, not bright golden yellow as in zonatula. The best character I have found in the antennae, which in balassogloi are distinctly longer than in zonatula; the first flagellar in balassogloi is about 3.5 times as long as its apical width, in zonatula less than 3 times, the length of the first four flagellar segments in balassogloi being in the ratio 28.5 : 10 : 10 : 10, in zonatula 25 : 10 : 10 : 10. In both species the pygidial plate is flat, finely transversely striate, the sides only slightly converging towards the rounded and almost truncated apex. Distribution. — Caucasus and Transcaspia.

1948. Popov, Doklady Akad. Nauk URSS, new ser. 59: 1674 and 1675, footnote (syno- nymy).

Although I have not seen specimens, it is evident from the description that this bee is a true Habropoda, most closely related to H. zonatula Smith, with which the species was compared by CockERELL himself. The male is described as having the characteristic long backwardly directed spine at the anterior coxa and the greatly flattened lamina at the hind basitarsus, thus agreeing with the European species. I have adopted the synonymy as given by Popov; yet it seems necessary to compare GUSSAKOWSKIJ's figures of the leg structure of H. alashanica with the type of pekinensis in the U.S. National Museum, Washington.

Distribution. — West and East China.

Asiatic species described in Habropoda, or doubtfully referred to Emphoropsis but requiring further investigation, are the following (arranged in chronological order):

H. radoszkowskii Dalla Torre, 1896 (Cat. Hym. 10: 285, nom. nov. for Habropoda montana Radoszkowski, 1882 (Wiadom. nauk przyrodz. Warszowa 2 : 77, 92 & Himalaya, nec Anthophora montana Cresson, 1869).

1) Of the legs RADOSZKOWSKI says: ‘ la base de chaque trochanter des pattes antérieures on voit une forte apophyse pyriforme d'un jaune pâle, avec l'extrémité émoussée; les jambes de cette paire sont renflées au milieu; les cuisses des pattes postérieures trés renflées, creusées un peu en gouttiére, les jambes assez renflées et le premier article des tarses dilaté, applati et extérieurement bordé de pils gris.” (loc. cit: 335).

M. A. LIEFTINCK : Notes on Anthophorine bees 145

I have not been able to locate the type of H. montana but FRIESE (1897 : 305—306) refers to the latter by quoting the latin diagnosis (‘“ 2 sarothrum rufo, metatarso posteriori nigro-villosis; & tibiis anterioribus fortiter albido-ciliatis, metatarso posteriori dente auriculato terminato.”). A female in the British Museum from Sikkim, Darjeeling, 7000 ft., 4.94, identified by BINGHAM himself, conforms exactly with his description and figure (1897), as do two unnamed females from Kumaon, United Prov., W. Almora Div., Nov. 1919, H.G.C., in the same museum. However, the leg structure of a conspecific male (Shillong 10.03, TUR- NER coll. 1912-111) differs from that described by BINGHAM, who writes: “posterior femora very slightly swollen, each posterior tibia produced at its inferior apex into a compressed, thin, rounded plate.” As it is not the unmodified tibia but the posterior basitarsus which is produced apically (thus conforming with RADOSZKOWSKI's statement), the sexes were probably wrongly associated by BINGHAM. Also in the British Museum collection is a good series (both sexes) of a closely similar species recently collected in the Taplejung District (East Nepal Exped. 1961—62). Though undoubtedly closely related, these Shillong and Nepalese bees differ from each other both in structure and body colour, despite the fact that all agree in having the posterior tibia unmodified and the basitarsus widened and provided interiorly with a smooth ridge ending in a blunt tooth. An examination of the hidden sternites reveals that all of them are unquestionable Habropoda. These plates, though less heavily sclerotized than in the more typical members of the genus, are of the same characteristic form, markedly constricted and transversely ridged about half-way their length and provided apically with the same minute papillae. The same applies to at least three more species from various high altitude localities in the Himalayas and Assam (Shillong), of which specimens are available for further study in the British Museum collection.

H. krishna Bingham, 1908 (Rec. Ind. Mus. 2 : 366—367, & Sikkim, Darjee- ling, 7000 ft.).

Status uncertain. The author says that it comes nearest to H. radoszkowskii, as determined by him. Whole body densely covered with long brownish yellow pubescence. Mandibles and clypeus white, only the sutures of the latter black. Orbits parallel. Ocelli in equilateral triangle, but description of their position obscure. Legs normal.

H. turneri Cockerell, 1909 (Entomologist 42: 308, 9 Shillong Assam).

Male unknown. A mounted female in perfect condition (British Museum coll.), now before me, bears TURNER’s written label “Shillong 9.03” and a second printed one with “Assam R. E. Turner 1910—225”. This is obviously a topotype, agreeing with the original description in every respect. A densely pubescent bee with a strongly contrasting Bombus-like colour pattern of black, canary yellow and orange-red. Contrary to COCKERELL’s statement on the type, the present example is compactly built and of normal proportions. The face and mouth- parts as well as the placement of the ocelli are as in Habropoda; the slender sickle-shaped mandibles bear a single subapical interior tooth and the tongue is of moderate length. Unusual features are (1) the greater length of the marginal

146 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

cell of the fore wing and (2) the minute size of the pulvilli between the tarsal claws, characters which it shares alike with H. mimetica Ckll., from China, which appears to be closely allied.

H. tainanicola Strand, 1913 (Supplem. Entom. Berlin 2: 51—52, ® For- mosa).

Male unknown. Position of first recurrent vein of fore wing slightly variable: usually received slightly before end of second submarginal, more rarely interstitial with its distal side. Body pubescence of head, thorax and gastral segments 1 to 3—4 black, for the rest orange. Clypeus prominent, black. According to STRAND the species resembles H. radoszkowskii D.T. (sensu BINGHAM!)

H. rowlandi Meade-Waldo, 1914 (Ann. Mag. Nat. Hist. (8) 13: 50—51, 2 4 Shillong Assam).

Appears to be allied with H. turner: Ckll., the male of which is unknown. The male of rowlandi has the clypeus totally pale yellow without any indication of a keel; the antennae are wholly black, the scape not yellow, as is so prevalent in males of this genus. In the female the face is all black, the legs ferruginous and the pubescence golden brown. I noted that the type (no. 637), in the British Museum, is not a true Habropoda, but the terminalia of the male have not yet been examined.

H. hookeri Cockerell, 1920 (Ann. Mag. Nat. Hist. (9) 6: 202—203, 2 Simla, 7000 ft. and 9 Mussoorie, 7000 ft.).

Male unknown. According to COCKERELL nearly agrees with H. radoszkowskii D.T. (= montana Rad.), as described by BINGHAM. It is held distinct from that species on account of the unmodified and not specially broadened hind tibia. These are, however, characters of the male, not of the female, and since COCKE- RELL had no male of hookeri, this distinguishing character does not hold good.

H. mimetica Cockerell, 1927 (Amer. Mus. Novit. 274: 15, 9 Yen Ping, China).

According to COCKERELL, this species is allied to H. turneri Ckll. The male has not so far been described but will, it is hoped, be made known soon. I have examined a series of both sexes from Fukien (SE China) and, as these do not fit the diagnosis of either Habropoda and Elaphropoda, a new genus (or subgenus) will be necessary to accommodate the species.

H. sutepensis Cockerell, 1929 (Ann. Mag. Nat. Hist. (10) 4: 132—133, & Siam).

A small, densely pubescent species with normally shaped legs and a non-pro- tuberant yellow clypeus. I have examined the types of either sex in the British Museum collection (&, no. 652), the female having also been described by COCKERELL. The species approaches Elaphropoda in several characters but probably requires a new generic (or subgeneric) name to hold it.

M. A. LIEFTINCK : Notes on Anthophorine bees 147

H. nubilipennis Cockerell, 1930 (Ann. Mag. Nat. Hist. (10) 6: 52, 9 Foochow, China).

I agree with COCKERELL that the type, which I examined in the British Museum collection (no. 645), is not the female of H. percarinata, the latter being now transferred to Elaphropoda. The two species are not even congeneric but the exact status of »ubilipennis (male unknown) remains to be established. The head of H. nubilipennis is shaped differently, the clypeus being shorter, considerably less swollen than in Elaphropoda, while the brown face marks are more sharply defined and shaped otherwise, as compared with members of that genus. It ap- proaches a Chinese species-group of which H. mimetica is one of the participants but, pending the discovery of the male, this is all that can be said.

H. sinensis Alfken, 1937 (Ent. & Phytopath. 5 : 404—405, ® 4 Chekiang, China).

It is absolutely impossible from the description alone to obtain an impression of this bee, nearly all characters mentioned being insignificant.

This New World genus is included here for comparison with related taxa in the Anthophorini. For descriptions of the type-species, E. laboriosa (F.) (= flori- dana Sm.) and other members of the genus, the reader may be referred to the existing literature, the fullest characterization having been published recently by MITCHELL (1962). In the same year, TIMBERLAKE (Ent. News 73 : 36—38) described E. excellens Timb., an aberrant species from California, the male of which differs remarkably from other members by the structure of its antennae and legs.

Of the described species I have been able to examine both sexes of E. depressa (Fowler), dammersi Timb., interspersa Ckll. and miserabilis (Cress.); also the males of E. laboriosa (F.) and pallida Timb.; and a female of E. rugosissima Ckll. In general appearance all these species are closely similar to members of Anthophora with which they occur together in parts of their range. The generic characters of the venation are those enumerated and illustrated by PATTON (1879) and MITCHELL (1962). In all species examined the first recurrent vein in the fore wing is received just before the second intercubitus and the transverse median

148 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

is placed slightly postfurcal (fig. 21); in several /aboriosa and a male of E. mise- rabilis these veins are interstitial or coincide in one point, as is also the case in the Chinese ‘“Habropoda” and all Elaphropoda (fig. 23). It will be seen that the latter differs from Emphoropsis in the much longer marginal cell and numerous structural characters. MICHENER (1944) has suggested that some of the bees described in Habropoda from East Asia (e.g. China) are in reality Emphoropsis. This may be true, as the resemblance is quite striking. In the Chinese species group the venation is scarcely more like true Habropoda than Emphoropsis, but since not one of the East Asiatic forms has yet been studied in sufficient detail, a decisive answer to this question can not yet be given.

Integument dark brown or black, the face, legs and parts of abdomen often predominantly light coloured (ochraceous-orange). Pubescence throughout short and scanty, except on thorax, where it is long and dense; plumose hairs behind orbits, on thorax, and partly also on legs and gastral sternites. Disk of labrum and clypeus sparsely covered with long, erect, bristle-like hairs. Abdomen comparatively long and narrow, that of male even more slender with pointed apex, the intermediate and terminal segments cylindrical in cross-section (fig. 35). Integument well exposed under the short tomentum, tergites not distinctly banded but posterior margins usually with narrow fringe of dense appressed pubescence; hair fringes of sternites longer, erect and plumose.

Head. Labial palpus 4-segmented, longer than galea, first segment very long and attenuated, about three times as long as second, the two apical segments small (fig. 19, 87); galea of proboscis extending back to or slightly beyond base of hind coxa in repose and when extended much longer than abdomen; glossa very long, with appressed pubescence, distal one-third with longer erect hairs. Maxil- lary palpus subequal in length to stipes, very slender, 6-segmented, second seg- ment longest, separate segments in the ratio of 6 : 23 : 16 : 11 : 7 : 5, about the same in either sex of all species (fig. 18). Structure of head, fig. 4 and 81. Face narrow, inner orbits subparallel, curvature slightly inwardly convex, shortest distance between eyes about midway their length in full frontal view. Ocellorbital distance about twice broader than interocellar distance, but only one-half of the clypeocellar distance. Clypeus longer than its distance from anterior ocellus (clypeocellar distance) and much longer than its width at base (about 5 : 3); strongly protuberant, usually with distinct median longitudinal keel, its greatest depth in side view about equal to diameter of eye. Frontal carina poorly developed, reduced to a short elongate, antero-median tubercle situated at level of antennal sockets. Ocelli placed in a triangle, closely approximated, the anterior one largest, its distance from either posterior ocellus about one-third of the interocellar distance. Malar space distinct, though short, one-seventh to almost one-tenth of its width. Labrum subcordate, only little wider than long, its anterior border entire, but apex distinctly produced. Mandibles with two well-developed interior subapical teeth, the proximal tooth shortest (fig. 82). Antenna slender, of normal length, flagellar segments longer than wide (10 : 8); first joint of flagellum much widened towards apex; ratios of length and breadth as 12 : 9 (4 ) and 17:9 (2); length ratios of first four flagellar segments as 12 : 6 : 10 : 10 (&) ande 4068553105 210. ADE

Wings as for tribe, with short narrow stigma. Marginal cell of fore wing much longer than distance from its rounded apex to wing tip, free part of marginal cell only little shorter than rest of cell; first submarginal cell shorter than second and third together but longer than third, the second much the shortest though rather high and squarish, with its costal side little shorter than the anal; costal side of third submarginal likewise shorter than anal side; first recurrent vein invariably interstitial with second intercubital vein; fork of basal vein coincident with transverse median, which is hardly curved. Hind wing with transverse median vein moderately oblique and outwardly convex, about half as long as its distance from the fork M-Cz, the second abscissa obsolete beyond half-way length of M; jugal lobe small, lanceolate (fig. 23).

Legs slender, coxae not modified, unarmed; trochanter of hind leg of male enlarged, angular and produced backward, its posterior (caudal) surface flat- tened, that of female simple and rounded. Hind femur of male conspicuously inflated, its inner surface flat and bounded by two longitudinal keels, the inner- most acute, the outer blunt; hind tibia laterally compressed, the inner surface smooth, shiny, slightly hollowed out and bounded by longitudinal sharp keels, in side view the tibia is strongly widened towards apex, ending in a triquetrous lamella. Claws similar in both sexes, deeply cleft, inner ramus shorter and more robust than outer; orbicula and pulvillus (arolia) well developed (fig. 17).

150 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

Scopal hairs of female not plumose, rather short and sparse, not at all concealing surface. Basitibial plate of female distinct, subtriangular, apex narrowly rounded, that of male similar and of equal size but poorly defined and this only at extreme apex, which is subacute.

Abdomen slender, more cylindrical than in allied genera, often with in- tegumental maculations; pubescence short and sparse, segments not or only narrowly banded. Seventh gastral tergite of male strongly tapered, sixth sternite usually more distinctly so, apex subacute. Seventh and eighth sternites unmodified, thin and delicate, disk of the former broader than long, finely pubescent with abruptly pointed apex, the latter subrectangular, apex emarginate. Gonostylus at apex of gonocoxite distinct and bipartite, consisting of a long, thin, plate-shaped exterior process, situated dorsad, and a slightly shorter, cylindrical or rod-like interior process, placed more ventrad; penis valves (sagittae) robust and thick, strongly incurved, the broad apices emarginate and/or toothed; membranous midlobe of penis short, transverse. Pygidial plate of female subtriangular, slightly longer than its width at base, apex very broadly rounded.

Type-species: Habropoda impatiens Lieftinck, 1944.

Though previous discoveries in Malaya, Borneo and China include bees closely comparable with E. impatiens, I have selected this form as the type-species as it is the only one of which both sexes were fully described and illustrated.

The species placed in this new genus recall Apis in stature and general ap- pearance, especially the female. They can be easily distinguished from Anthophora, Habropoda and Emphoropsis by the tridentate mandibles, closely approximated ocelli, sparsely pubescent legs and abdomen, and the great length of the marginal cell of the fore wing. Additional features both sexes have in common are: extremely attenuated mouth-parts, strongly elevated narrow face and conspicu- ously light-coloured legs. Males have modified hind legs and a pointed abdomen, the tapered form of the last visible segments being noteworthy. The apical sternal plates and genitalia are altogether different in shape from those of the allied genera, the former being flat, delicately pubescent structures (fig. 33—34, 41—42, 47—48, 76—80, 84—86, and 88—92). The characters of the legs, venation and genitalia at once exclude relationship with certain species of the Amegilla florea (F. Smith) assemblage, which they resemble at a casual glance. Some of the latter are equally striking for their strongly protuberant facial parts, enormously lengthened glossa and short pubescence; they are, however, at once separated by the absence of pulvilli (arolia) between the tarsal claws.

It is of interest also to compare Elaphropoda with Deltoptila LaBerge & Mi- chener (1963), recently proposed for a group of Anthophorini occurring in Middle America. The authors found it to resemble Habropoda more nearly than it does Emphoropsis, especially in regard to the slender form of the legs, the short and sparse scopal hairs and, especially, the equilateral ocellar triangle. Deltoptila includes several species doubtfully placed in Habropoda by early American writers and it will be clear that the authors of the new taxon were entirely justified to remove it therefrom and place it in a genus of its own. It should be borne in mind that Deltoptila was compared with Habropoda at a time

M. A. LIEFTINCK : Notes on Anthophorine bees 151

when Elaphropoda had not yet been separated from it as a distinct genus. It is exactly with the last-mentioned group that Deltoptila was primarily compared, sharing with it the long proboscis, unusually protuberant face and the features already mentioned. This resemblance is rather surprising but on the other hand there are well marked differences between the two. Chief amongst these are: the longer malar space of Deltoptila, the single inner tooth at its mandibles, the much shorter 2nd and 3rd segments of maxillary palpi, the shorter submarginal cell of the fore wing, and the different male genitalia and apical sternal plates.

Significant specific characters appear to be slight and few in number. Nearly all species have been described from single individuals of either sex, thus making it quite impossible to form an opinion about the consistency of any given character. For instance in E. impatiens, the only species of which good series of both sexes are available, the extent of “red” colour on the gastral segments was found to vary considerably between individuals and thus proved of no help in the separation of species. In regard to body sculpturing and degree of hairiness all known species seem to be practically alike, even the male sexual organs hardly showing distinctive differences. Under the circumstances all that could be done was to profusely illustrate the few characters most likely to be constant, i.e. the shape of the hind tibia and the penis valves of the male genital apparatus. For details not mentioned under the species discussed hereafter, see the comprehensive specific descriptions of E. impatiens (Lieft.) in the writer's previous paper (1944).

Distribution. — Sumatra (terr. typ.); from the Himalayas to southeast China, and through Burma and Malaya to Java and Borneo.

Remarks. — Restricted to the humid rain forests of the lower mountain zone (1450—1700 m alt.). Owing to this peculiar habitat and the extremely swift flight of Elaphropoda, these bees are easily overlooked and very rare in collections. The two species known from Sumatra and Java were both caught on flowers of Impatiens (Balsaminaceae). The same species in Malaya, Sumatra and Java are presumably parasitized by their nearest melectine relatives of the genus Callo- melecta Ckll. discussed also in my 1944 article.

1920. COCKERELL, Ann. Mag. Nat. Hist. (9) 6: 201—202. — & Kumaon (Habropoda fletcheri, sp. n.) Syn. nov.

Material. — The types of these two Himalayan species were examined by me in the British Museum collection (#agrettii, no. 638). Both are from Kumaon (northern United Provinces, W of Nepal), COCKERELL’s specimen of fletcheri bearing a label “Kumaon, Ramgarh, 6000’, viii.1918, Fletcher”.

A third male, now before me and in the British Museum under H. magretti Bingh., is labelled “Shillong 9.03” (written) and “Assam R. Turner 1905—125” (printed). It agrees with my notes on the type but was received too late for dis- section, figuring and incorporation in this paper. It is a rather small specimen with light-coloured legs, only the bases of all femora being diffusely brown. The

152 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

inner outline of the hind tibia when viewed from below is distinctly undulated, thus differing from the figures here presented for related species. This male probably is correctly identified.

Clypeus not carinate down the middle, lacking the longitudinal keel so well pronounced in most other species. In the original description of fletcheri this bee is said to be less robust than magrettii, with black femora and dark apex of abdomen. The first statement I am unable to confirm, while the only point of distinction between the two relates to body colour, which, as I have shown for zmpatiens, in this group varies greatly between individuals when good series can be compared. The gastral tergites in all males of either magretti and fletcheri are dull black with faint blue and purplish reflections, lacking “red” areas, only the hind margins of the segments being broadly testaceous, as they are also in the Chinese E. percarinata (Ckll.), which has, however, a sharply defined clypeal keel. In general appearance and venation these bees are quite similar to E. moelleri and other members here united, but the male sternites and genital organs of the types could not be investigated; further material of the present species from the same country is therefore needed to decide on the relationship of these closely similar bees. I have no doubt that magrettii and fletcheri are conspecific.

Distribution. — Northern India and ? Assam.

This bee is a true Elaphropoda, conforming in every respect to the diagnosis of that genus. COCKERELL (1922) already pointed out that CAMERON’s male of fulvipes does not belong here but is a halictine (Thrinchostoma spec., possibly sladeni Ckll., 1913), CAMERON having been led astray by comparing his specimen with BINGHAM’s picture of the male of E. magrettii (Bingham), a totally different bee; and by wrongly associating the sexes he naturally considered his female to represent a new species. In an earlier paper COCKERELL (1920) refers to a (topo- typical!) male from the Khasia Hills he received from Mr. SLADEN, which he characterizes as follows: “... the face below the antennae is entirely rich chrome- yellow and the clypeus is carinated. The scape is yellow in front. The abdomen has the first two segments red”. I have not seen this specimen, but since the last- mentioned brief description applies to any other species of the group except magreitii (which has no clypeal keel), its identity must remain doubtful. It may be conspecific with E. moelleri (Bingham), described from a male, but as long

M. A. LIEFTINCK : Notes on Anthophorine bees 153

as no direct comparisons can be made of the structural features of these bees, nothing definite can be said. Distribution. — Assam and ? Siam.

Although SCHULZ wrongly considered Anthophora fulvipes Eversmann, 1846, and Habropoda fulvipes Cameron, 1904, to be congeneric, we have to accept the substitute name &Aasiana Schulz for this species, fulvipes Cameron being a junior secondary homonym of fulvipes Eversmann.

The present 4 agrees well with the type and original description, except that only the first gastral segment is entirely “red”, the disk of the succeeding segments of the abdomen being obscured, exactly as in magretti and dark individuals, males as well as females, among our series of E. impatiens from Sumatra and the Malay

Peninsula. Here again we meet with colour differences which are obviously of no use for specific discrimination.

Whole anterior surface of head, including labrum and most of the mandibles, honey yellow, except a pair of dark ferruginous hair-lines running from the transverse clypeal suture down along subantennal grooves to tentorial pits; yellow lateral face marks extending upward along eye-margin to upper margin of antennal sockets. Supraclypeal mark triangular, 2%, times broader than high, surface on top of this mark slightly raised, forming a low tubercle. Anterior face of antennal scape honey yellow, tawny behind; pedicel dark brown; flagellum ochraceous tawny, apical portion of first and basal part of second flagellar segments lighter. Hind leg (except coxa and trochanter) entirely pale, basitarsus not obscured.

Terminalia very similar to those of the allied species, as in fig. 76—77 (the 7th sternite was damaged and lost).

The following additional features, taken from the single male now before me, may or may not be of specific value as they would seem to apply to most, if not all, species examined.

Labrum widest about half-way its length, only little longer than wide (43 : 40). Length and basal width ratio of clypeus 50 : 32. Clypeocellar distance shorter than length of clypeus (40 : 55). Anterior length ratios of first four flagellar segments of antennae 13 : 5 : 10 : 10. Hind tibia about twice as long as its width at apex, measured along inner margin; inner aspect of hind tibia, see fig. 71.

Were it not for the strongly developed clypeal keel, moelleri would come very near magrettii, but on the strength of this important character, I prefer to keep the species apart.

There is almost complete agreement between the type series and the additional examples from NE Sumatra and the Malay Peninsula, the latter exhibiting the

M. A. LIEFTINCK : Notes on Anthophorine bees 155

same amount of variation in the abdominal colour pattern. This was described by me earlier and need not be repeated here. In fig. 23 of the original description the face marks of the male are incorrectly shown to extend inward behind the antennal sockets. This is due to the fact that the similarly coloured dense hair tufts on both sides of the frons were mistaken for integumental spots; in reality the paraclypeal area is coloured exactly as in E. bembidion sp. n., as shown in fig. 4 of the present paper. It will be seen, however, that the latter differs from

impatiens by having a pair of conspicuous dark blotches on the clypeus (fig. 81). The supraclypeal mark in both sexes of zmpatiens is invariably shaped like a broad triangle, as correctly indicated in fig. 23 of the earlier paper. Despite the very close similarity in general appearance, colour and pubescent pattern, the specimens from Burma, Malaya and Sumatra are not quite alike with respect to certain structural proportions. The clypeocellar distance and length of clypeus are in the ratio of 40 : 50 (Burma and Malaya), as against 40 : 55.6 (Sumatra); the length and basal width of the clypeus and median interorbital width are in the ratios of 50 : 32 : 60 (Malaya and Sumatra) and 50 : 32 : 56 (Burma). Slight dif- ferences were also noted in the configuration of the hind tibiae as seen from beneath (fig. 72—74), but when viewed from the side the shapes and propor- tions were found to be nearly identical.

156 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 6, 1966

The Burmese male is a worn specimen whose coloured pubescence has lost much of its freshness. In this specimen the first gastral segment and a pair of transverse spots (one on either side) at the base of the second, are “red”, the hind margins of 2—6 being broadly bordered with ochraceous, thus differing from the others in which these segments are only narrowly light-bordered. Now COCKERELL (1927) records E. khasiana (Schulz) from Peninsular Siam, so that the present male may belong to that species rather than zmpatiens? Its tibia is shown in fig. 72, the terminalia in fig. 78—80.

Distribution. — Sumatra and the Malay Peninsula (universal); ? Lower Burma.

Remarks. — I came across this elusive species again in northern Sumatra under circumstances almost identical to those during my collecting trip in 1939 and 1940 to south Sumatra. I wrote about these as follows: “On Mt. Tanggamoes H. im- patiens was strictly confined in its visits to one particular kind of flower, viz. a wild Balsam, Impatiens cf. oncidioides, with large yellow flowers carrying long curved spurs. Patches of this hygrophilous plant were found in damp shady situations, chiefly in trenches and other gloomy places beside the long-abandoned track on the edge of the dense virgin forest. Once arrived there, we were soon struck by the shrill note of impatiens which flashed hither and thither among the low herbage. The males kept up a continual flight over the flowers which only the females searched for honey and pollen; the males greatly outnumbered the females and alighted only rarely in sunlit openings, on leaves and tiny branches; they were exceedingly alert and difficult to capture when ranging over the flowers in search of the females. Curiously enough, the insects were most abundant when the weather was dull and were active even when it was raining. Although common in this restricted habitat and possibly breeding gregariously, we have been unable to find the nests. H. impatiens is probably the host of Cal- lomelecta vulpecula, which was captured in the same locality and on the same days.” (LIEFTINCK, 1944 : 90—91).

(Lieft.), but differing in details of coloration, armature of legs and abdominal terminalia, as follows.

Male. — Mouth-parts, greater part of face and scape of antenna anteriorly, deep chrome, the malar space, teeth and apex of mandible, dark ferruginous. Face marks, frons and antennae dark brown, only the distal portion of first flagellar segment of antenna red brown; orange supraclypeal mark high and nar- row (fig. 81). Legs rufous, the coxae and trochanters hazel; outer face of hind femur slightly darker towards apex, the basitibial area and hind basitarsus dark brown. Wings more strongly tinged with yellow than in E. zmpatiens, but the neuration as in that species. Integument of gaster coloured as in the darkest in- dividuals of E. impatiens, i.e. no ‘‘red” areas on basal segments; instead, the hind margins of all tergites are more broadly pale coloured (cinnamon-buff) than in impatiens, the apical bands occupying only little less than half of the exposed surface of segm. 1—5, the sternites on the contrary being predominantly dark brown. Body pubescence as in E. impatiens.

Structure. — Clypeocellar distance and length of clypeus in the ratio of 40 : 54.5; length and basal width ratio of clypeus 50 : 30; length ratios of first four flagellar segments of antenna, 12 : 6 : 10 : 10. Clypeal keel well developed, similar to E. impatiens. Inferior keel of hind tibia more sharply pronounced than in impatiens, the apical lamella distinctly more drawn out in lateral view and narrower, the apex almost pointed when looked at from beneath (fig. 83). Length of body 15 mm approx., length of fore wing 11 mm.

Frontal view of head as in fig. 81; mandible, fig. 82. nmel very similar to those of the allied species (fig. 8486).

Immediately distinguished from its allies by the well-developed dark brown clypeal marks, which in the males of all other described species are reduced to narrow dark stripes, often mere hair lines extending along the subantennal suture as far as the anterior tentorial pits, the clypeus itself remaining unmarked. The species is also remarkable for its darker wings, which are deeply stained with yellow. The female remains unknown.

Distribution. — Borneo.

general they agree with the type but differ by having the greater part of the anterior face of the antennal scape definitely yellow, though the yellow area is not sharply defined. In the original description no mention has been made of the consistency of the long hairs covering the clypeus on either side, the latter being

bristly, not abundant, brown on upper portion and becoming golden yellow anteriorly. The wings are exactly as described for magrettii and impatiens; the marginal cell in the type is erroneously described as “not greatly produced”, it being in fact of the same great length as in all other species of Elaphropoda. The tarsi of the type are described as “black or nearly so”, but I failed to notice any difference between our specimens and the type, in which they are ochraceous orange, only the basitarsus III being conspicuously dark brown, and the claws are tipped with black.

There are no “red” areas on the first two tergites in any of the present series, males and females, which thus differ from the type. The thin short pubescence on the disk of the gastral tergites is more dense than in any of the other species described, but the integument still remains well visible under the tomentum.

Male characters. — Clypeus relatively long, clypeocellar distance and length of clypeus in the ratio 40 : 56.5; length and basal width ratio of clypeus 50 : 30; length ratios of first four flagellar segments of antenna, 12 : 5 : 10 : 10. Details of structure, taken from two males collected at Shaowu (Tachulan) are illustrated (fig. 75 and 87—92).

COCKERELL compares his specimen with H. fulvipes Cam. (= khasiana Schulz) and magrettii, with which the species is, indeed, very nearly related. Distribution. — East China (Fukien).

Acknowledgements

My sincere thanks are due to ail entomologists who have assisted me in carrying out the present investigation, which is to be considered as a preliminary to further studies on a somewhat larger scale. It was started before I left Indonesia and is mainly based on material then received through the good offices of several cor- respondents abroad. Many of the illustrations were also prepared about that time, while others were supplemented only recently.

I am deeply grateful to the late H. M. PENDLEBURY, a learned scientist who before his untimely death was an entomologist at the Federated Malay States museum, Kuala Lumpur; his Malayan insect collections will long remain an im- portant source of information. Through the great kindness of Dr. P. H. TIMBER- LAKE, of the Citrus Experiment Station, Riverside (Cal.), I obtained representative species of various Nearctic anthophorines, while the late Dr. V. B. Popov and A. PONOMAREVA, of the Zoological Institute, Academy of Sciences (Leningrad), supplied valuable material of Eurasian Habropoda. The rich material given to me by Dr. T. C. Maa, from his expeditions in southeast China, also added a great deal to our knowledge of this group. Lastly, I am much obliged to the following persons and institutions who enabled me to study material in museums and private collections: Dr. G. BARENDRECHT, Laboratorium voor Toegepaste Ento- mologie (Amsterdam); Fr. P. BENNo (Babberich); Dr. M. CERUTTI and ELENA ETZELSDORFER, Istituto Nazionale di Entomologia (Roma); Dr. M.

BORNEAN FIG WASPS FROM FICUS STUPENDA MIQUEL (HYMENOPTERA, CHALCIDOIDEA)

BY

J. T. WIEBES

Rijksmuseum van Natuurlijke Historie, Leiden

ABSTRACT

The Agaonidae Blastophaga (Waterstoniella) masii Grandi, 9 6, and Blastophaga (B.) errata spec. nov., 9, reared from one and the same receptacle of Ficus stupenda Miq., are described together with other fig wasps from the same sample, viz. Agaonidae: Ceratosolen spec. near C. notus (Baker), & (contamination of the sample?); Sycophagine Torymidae: Arachonia borneensis spec. nov., 9, Sycoryctes hilli spec. nov, 9 8, Sycoscapter reticulatus spec. nov, 2 4 (including a possibly conspecific, giant male), Sycoscapteridea stilifera spec. nov., 2, Grandiana corneliae spec. nov, 9 4.

INTRODUCTION

One of the moot points in the hypothesis of specificity of figs and fig wasps, is the question whether two species of Agaonidae can live in one species of Ficus.

WILLIAMS (1928: 9—10) tried Blastophaga (Eupristina) bakeri (Grandi), the symbiont of Ficus forstenit Miq., on young figs of Ficus microcarpa Linn. f., and Ceratosolen notus (Baker) from Ficus nota (Blanco) Merr., on Ficus botryo- carpa Miq. It appeared that the wasps entered the foreign receptacles and, in the latter instance, oviposited in the gall flowers.

JOSEPH (1953a: 282; 1954: 409) recorded two specimens of Agaonidae from one species of Ficus, viz. Ceratosolen fusciceps (Mayr) and Blastophaga (Eupris- tina) belgaumensis (Joseph) from Ficus drupacea Thunb. var. pubescens (Roth) Corner. I suggested (WIEBES, 1963: 98) that these records might be due to confusion of the figs of the strangler Ficus with those of its host Ficus, either by the collector or by the wasps.

Figs of Ficus stupenda Miq., collected by E. J. H. CORNER in Borneo, attracted attention because of the many kinds of insect emerging (CORNER, 1964: 38). The insect fauna of these receptacles is described in the present paper, some Chalcido- idea not belonging to the Agaonidae nor to the Sycophagine Torymidae excepted.

HOST RECORDS FROM Ficus stupenda AND RELATED FIGS

A survey of the Agaonidae and Sycophagine Torymidae (Sycophilini excluded) from Ficus stupenda and related figs of subsection Conosycea (Miq.) Corner, is given in Table I. Ficus arnottiana Miq.

J. T. WIEBES: Fig wasps from Ficus stupenda 165

Blastophaga (Waterstoniella) jacobsoni Grandi), and Ficus forstenii Mig. (with Blastophaga (Eupristina) bakeri (Grandi)), are not included in this table.

I have the impression that the following species do not belong to the regular fauna of the figs listed:

Ceratosolen fusciceps (Mayr), known as the symbiont of Ficus racemosa L.;

Blastophaga errata spec. nov.;

Ceratosolen spec., close to C. notus (Baker) from Ficus nota (Blanco) Merr.;

Parakoebelea thalakvadiensis Joseph; the other species of this genus, P. stratheni Joseph, is known from Ficus racemosa L.

The Philotrypini, Sycoryctini and Otitesellini are abundant throughout the sub- genus Urostigma (Gasp.) Miq.

Philotrypesis transiens (Walker), P. travancoricus Joseph and Sycoscaptella affinis Westwood may actually be only one and the same species of Philotrypests. Terastiozoon keralensis Joseph seems to be identical with Walkerella temeraria Westwood. Redescriptions of these species will be presented in a separate paper.

The fact is now unambiguously established, that more than one species of Agaonidae can reproduce in the receptacles of one fig. The data suggest that there are some Sycophaginae too, that can develop in a fig specifically or even sub- generically distinct from their normal host. I feel that this conclusion, although it does not affect the general hypothesis of host specificity, should warn against too strict appliance of the principle in special instances.

AGAONIDAE FROM Ficus stupenda

A preliminary report on the pollinating insects from Ficus stupenda was presented to the XIIth International Congress of Entomology (WIEBES, 1965).

The Agaonid wasps reared from Ficus stupenda belong to Blastophaga (Wa- terstoniella) masii Grandi, Blastophaga (B.) errata spec. nov., and Ceratosolen spec. near C. notus (Baker). I am not sure that the Ceratosolen are not a contamination of the sample.

Galls situated side by side in the same receptacle, contained nymphs of B. errata and B. masii, respectively. This not only means that the females of these two species of Agaonidae entered the same young receptacle, but also that they ovi- posited, and that a new generation of both (females and males of B. mast, females only of B. errata) developed in one and the same fig.

Blastophaga (Waterstoniella) masii is the second species of the subgenus to become known in the male sex. The description of this male allows for a better evaluation of the relationship of the group.

Male. — Reference is made to Blastophaga (Waterstoniella) jacobsoni Grandi, the only male of the subgenus hitherto known. Dr. GRANDI sent to me some specimens from the type lot of B. jacobsoni (Fig. 9), for comparison with the present material of B. masii. Most drawings of B. jacobsoni (Fig. 8, 10—11), however, were made from another sample (coll. Mus. Leiden, no. 323) from the type locality (Bot. Gdn., Bogor, Java, ex Ficus crassiramea Miq., leg. J. VAN DER VECHT, 5.1V.1955).

B. masii is somewhat variable, particularly in the chaetotaxy of the legs. The same appears to apply to B. jacobsoni; cf. its description by GRANDI (1917: TP), Veta, IDO),

Head (Fig. 6) depress, transverse, nearly twice as wide as long, with scattered small hairs. Eyes relatively small. Mandible (Fig. 4) large, other mouth parts atrophied; a variable number of hairs occur next to the oral aperture. Antenna (Fig. 5) much like that of B. jacobsoni, but the flagellar segments relatively longer; the club entire.

Thorax (Fig. 6) large and wide, depress, with scattered small hairs. Pronotum with anterior and lateral expansions, as in males of Euwpristina Saunders; the mesonotum approximately twice as wide as its median length, with posterior parts next to the propodeum; the metanotum visible in dorsal aspect as two lateral sclerites. Propodeum almost completely separate, nearly as long as wide, the spiracular peritremata almost circular, lateral in position. Prosternum short and wide, the prothoracic episterna large. Fore leg, Fig. 1. The dorsal tibial spines, found in all specimens of B. jacobsoni studied (Fig. 8—9), lacking; apical armature of the tibia as in B. jacobsoni. First tarsal segment with conical spines in variable number, other segments with normal spines. In B. jacobsoni, also the second tarsal segment (Fig. 8) and in some instances the third (Fig. 9), bear conical spines; the number is variable, even in both legs of one specimen. Tarsal segments approximately in ratio 4 : 1 : 1 : 1 : 2. Mid leg, Fig. 2. The dorsal margin of the tibia without conical spines (present in B. jacobsoni, Fig. 10; although the number is variable); the ventral angle produced, with one axial conical spine, and one antiaxial. The tarsus with conical spines on the first segment only (in B. jacobsoni also on the second, and sometimes on the third); the segments approximately in ratio 10 : 5 : 5 : 5 : 8. Hind leg, Fig. 3. In comparison with B. jacobsoni (Fig. 11), the dorso-apical conical spines of the tibia are relatively smaller and more concealed by the pubescence; the bidental apical crest is more robust, the teeth being inequal; the dorso-apical angle is distinctly produced. The ventral conical spines on the first tarsal segment are again smaller than in B. jacobsoni; the second segment bears only one cone, while the axial side has a robust spine instead; the segments are more transverse, approximately in ratio 5 : 1:1: 1 : 5.

Remark. — At first sight the male of B. masii reminds one of a species ot Eupristina, but a closer examination reveals its true subgeneric position. The characters of the head, antennae and thorax, similar to those of B. jacobsoni, confirm Waterstoniella Grandi as a distinct group in Blastophaga Gravenhorst. It appears to be close to Ezpristina Saunders, which relation is better depicted in the new classification of Eupristina as another subgenus of Blastophaga (WIEBES, 1963: 100; GRANDI, 1963: 334), instead of as a distinct genus.

Female. — Head (Fig. 18) about as long as wide across the compound eyes; the short pubescence becomes longer towards the cheeks. Facial groove rather narrow. The cheek nearly one and a half times as long as the longitudinal diameter of a compound eye. Three ocelli. Epistomal margin trilobate, the lateral lobes not prominent. Mandible (Fig. 16) with 13 ventral ridges, its appendage with nine lamellae. Labium and maxillae (Fig. 14) with two long, apical hairs each. Antenna (Fig. 13) with eleven free segments, the last three of which are shaped so as to form a club; the scape twice as long as its maximum width, with a prominent ridge on the antiaxial disc, the dorsal and ventral margins hirsute; the pedicel short, with a few axial spines only; the third segment small, its appendage (Fig. 12) wide and blunt, reaching halfway the fifth segment; the fourth segment small, with apical hairs; the fifth and sixth little longer than the fourth but distinctly wider, with apical hairs and one row of large, oblong sensilla; the seventh to ninth segments with more hairs, and with two rows of sensilla each (more regularly spaced at the axial side than at the antiaxial); the tenth segment shorter than the seventh to ninth, and about as long as the sixth although much wider, with one irregular row of oblong sensilla (forming two nearly complete rows at the axial side) and many circular pits; the ultimate segment shortest, with oblong sensilla and many blunt, sensillar hairs. The characters of the antenna appear to be rather variable in the present series. The club may consist of only two, sub- equal, distinct segments (numbers 9 and 10), and the number of sensilla may be larger, especially on the axial side.

Thorax almost glabrous. Pronotum rather short; the dorsal disc with small hairs in the posterior corners, the lateral parts with more, longer hairs. Scutum some- what wider than long, subglabrous, some six short hairs occur along the postero- lateral margins only, the parapsides with some hairs; the scutellum as long as wide, with approximately 25 short hairs; the metanotum glabrous except for approximately seven lateral hairs towards each lateral margin. Propodeum not very long, with five hairs before, and many more, longer hairs behind the

spiracular peritremata; some more, smaller hairs occur along the posterior margin. Wings with many microtrichae and few longer hairs. Fore wing (5 : 2), 2.0 mm long; the submarginal, marginal, stigmal, and postmarginal veins in ratio 26 : 8 : 5 : 8, the submarginal and stigmal both with three pustules; the fringe rather short. Hind wing (7 : 2), 1.1 mm long; the fringe longer.

armature, almost glabrous on the disc, with hairs along the dorsal and ventral margins and a patch of finer pubescence on the axial disc close to the ventral margin; the tibia with a comb of three dorsal teeth and one ventral, anti- axially with several long hairs near the ventral angle and a row of shorter hairs along the dorsal margin, axially with a tuft of heavy spines on the disc; the tarsal segments with a few antiaxial, apical spines, and many more axials (as figured for the hind leg, Fig. 19), the length ratio approximately as 8 : 2 : 3 : 3 : 8. Mid leg slender; the femur shorter than the tibia, hirsute along the dorsal and ventral margins; a few hairs on the posterior disc, the anterior disc subglabrous; the tibia almost straight, with scattered hairs and one ventral spine; the tarsal segments approximately in ratio 22 : 12 : 11 : 9 : 16, with hairs and apical spines. Hind leg (Fig. 19—20): the coxa a little smaller than the femur, with small axial spines, glabrous antiaxially; the femur hirsute along the ventral and dorsal margins, and with some smaller hairs on the dorsal part of the antiaxial disc; the tibia two- thirds of the length of the femur, with stout hairs along the dorsal margin and on the discs (some spine-like hairs on the axial disc are blunt, and differently shaped from the others), the apical edge bears a hyaline ridge at the dorsal side, and two teeth (the one simple, the other bidentate) at the ventral angle; the tarsus rather wide, with axial hairs and spines, antiaxial spines, and a ventral fringe on all segments, the length ratio approximately as 17 : 7 : 7 : 5 : 8.

Gaster. The segments with long hairs, particularly along the caudal margins. Stigmata of the eighth urotergite (Fig. 17) circular; pygostyles with four apical hairs, one of which is short. The ovipositor and the valves are nearly one and a half times as long as the gaster.

Length (head, thorax and gaster), 2.7 mm. Colour blackish brown, the an- tennae, distal segments of the legs (from the tibiae onwards), and the ventral surfaces lighter.

Remark. — B. errata is immediately recognized from the other species of Blastophaga, e.g. by the head, in which the sclerotized parts are large, and the facial furrow narrow.

The remarkable fact that the rather long series consists of females only, may be due to abnormal conditions in the presumably foreign, host species.

median lobe wide, the lateral lobes more acute. Mandible (Fig. 29) bidentate. Maxilla (Fig. 27) not or scarcely expanded laterally, with two long hairs. Antennal grooves open, but not very long; this may be a variable character, as in the second specimen the grooves are relatively longer (Fig. 24). Antenna (Fig. 26) five-segmented; the scape (2 : 1) twice as long as the pedicel (4 : 3), and much wider; the first and second flagellar segments as wide as the pedicel, the second of the same length (in ventral aspect; much shorter in dorsal view), the first half as long; the ultimate segment tapering distad, little more than twice as long as the pedicel; hairs as in the figure.

Fore leg (Fig. 30) rather slender, particularly the femur, which is more than twice the length of the tibia including the apical armature; the femur subglabrous; the tibia

172 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 7, 1966

with some long subapical hairs, four dorsal teeth (one of which is small), and three ventrals; the bimerous tarsus with four stout, axial hairs on the first segment, the segments approximately in ratio 7 : 6. Mid leg (Fig. 25): the coxa subequal in length to the femur; the tibia distinctly longer, slightly arcuate, with apical teeth, four of which are visible in posterior aspect; the tarsus pentamerous, oligo- merous in one of the legs of the first specimen (Fig. 25), the segments ap- proximately in ratio 5 : 3 : 2 : 2 : 8. Hind leg (Fig. 21) pubescent; the coxa with a dorsal hyaline ridge reaching half length, and heavy axial pubescence; the femur and tibia pubescent on the axial surfaces; the tibial armature (Fig. 22) inconspicu- ous, consisting of two antiaxial teeth, and one smaller, axial; the metatarsus nearly half as long as the tibia, the tarsal segments dilated and pubescent, their length ratio approximately as 10:7:7:6:8.

Gaster. Claspers (Fig. 28) of the genitalia with three claws; parameres present.

Length (head and thorax), 1.4 mm. Colour uniform yellowish brown.

Remark. — In my key to the Indo-Australian species of Ceratosolen Mayr (WIEBES, 1963: 88—91), this Ceratosolen spec. runs to couplet 26, and appears to be rather close to C. notus (Baker). It differs in various characters, e.g. the pubescence of the head, the shape of the antennal grooves, the straight lateral edges of the maxillae; C. notus, moreover, is more robust and distinctly larger.

The find of the males of Ceratosolen spec. in the sample from Ficus stupenda led me to the record of 1965 (WIEBES, 1965: 95—96), but on closer examination the females taken from the galls situated side by side with those of Blastophaga masti, appear to belong to Blastophaga errata. The two males of Ceratosolen were found in the tube of insects accompanying the entire figs from which I took Blastophaga masii, B. errata, Arachonia borneensis, etc.; 1 could not find any more specimens of Ceratosolen in the figs.

More males and females of this Ceratosolen were collected by E. J. H. CORNER during the same expedition to Borneo, from figs of Ficus cf. nota (Blanco) Merr. (without number 2), at Kota Belud, North Borneo, 23.IX.1961; coll. Mus. Leiden, nos. 630, 632. I refrain from naming the form until I have studied the rich col- lection of insects from Ficus nota and its allies, made during a recent trip to the Philippine Islands. The alliance of Ceratosolen notus contains some closely related forms, the status of which should be reconsidered now that more material is available.

SYCOPHAGINE TORYMIDAE FROM Ficus stupenda Sycoryctini

Ovipositing organs of some of the female Sycoryctini from Ficus stupenda were figured by WIEBES (1966). In the same paper the Indo-Australian genera of the tribe were listed. A provisional key, mainly based on the criteria applied, though not explicitely stated, by JosEPH (1957), may show the characters used for the generic distinction of the females.

2) CORNER (1962, in litt.) noted: “I am not sure that the Bornean plants are the same as the Philippine F. rota”.

as the pedicel; the pedicel robust; the funicular segments subequal, with rows of hairs, and lateral sensilla; the ultimate and penultimate segments of the club sub- equal in length, with sensilla, the basal club-segment half as long, without sensilla.

Thorax (Fig. 52) with scattered small hairs. Pronotum longer than wide (5 : 4), with straight lateral edges; the mesonotum of a complicate structure, with lobes and ridges, some hyaline protuberances between the lateral lobes probably represent the wing-remnants 3); the metanotum visible from above as two narrow sclerites laterad of the posterior quarter of the mesonotum and the anterior third of the propodeum.

Gaster. The first segment (second abdominal segment; Fig. 52) has the shape of a petiole. Genitalia, Fig. 59; the claspers with four claws, the parameres with two hairs.

Length (head and thorax), 1.0 mm. Colour yellow-brown.

Remark. — The type species of the genus Sycoryctes Mayr needs to be re- described, so it seems best to compare the new species with one of the better known species of the genus.

The female has two antennal ring-segments, versus one in S. trifemmensis Joseph (1957 : 110—113, Fig. VIII), there are more spines along the apical margin of the fore tibia, the hind tibia bears spines along the dorsal and ventral margins, which appear to be lacking in S. irzfemmensis.

The male is distinct from any of the species described in Sycoryctes, both in its general shape and in the structure of the antenna. I place it here, because in another sample of fig wasps I found a similar male associated with a female

3) The material is too poor for a more extensive description.

180 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 7, 1966

apparently belonging to Sycoryctes. Moreover, the longitudinal ridges of the propodeum are also found in the other species of Sycoryctes.

It is a pleasure to name the new species to D. S. Hitt M.Sc., Commonwealth Institute of Entomology, London, who studies the fig wasp fauna of Hong Kong.

Saunders, the female of which was described by JOSEPH (1953 : 77—81, Fig. 73—86) as Indothymus crenulatus. It differs in some important characters, viz. the female is much larger and more robust, and the reticulate sculpturation is heavier; the median process of the epistomal margin is less prominent (the dif- ference between S. insignis and S. reticulatus seems to be of the same magnitude as that between Sycoscapter inubiae (Ishii) and S. gajimaru (Ishii), respectively; cf. IsHu, 1934: PI. 1 fig. 12 and 20); there are more sensilla on the antennal segments, and they are more regularly placed; there are more apical spines on the fore tibia, particularly at the dorsal angle; there are about one and a half times

as many spines along the dorsal margin of the hind tibia, and the spines are larger; the ninth urotergite is relatively longer in S. reticulatus than in S. insignis.

Although the male shows several differential characters, e.g. in the shape and structure of the wing remnants (which are more filament-like in other species of Sycoscapter), I am confident that it belongs here. The larger male alluded to in the description differs in size and in the shape of the head (cf. Fig. 78—79), but it is otherwise essentially similar, and evidently conspecific.

Another male, of unknown relationship, is described below. In presumably essential characters, it is similar to the males described above, and it may be a giant form of S. reticulatus. It is, however, aberrant in shape and to a less degree, in the spines of the legs and the genitalia, so as to make the specific identification uncertain.

Male, giant form (Fig. 80—89). — Head (Fig. 80, 87) large and robust, slightly wider than long. Compound eyes rather large, no ocelli. Epistomal margin shallowly emarginate, the median part indistinctly invaginated. Mandible (Fig. 84) short and robust, with two glands. Maxillary palp (Fig. 85) four-segmented, the segments approximately in ratio 8 : 10 : 4 : 9, with many long hairs, particularly on the dorsal discs of the first and second segments. Labial palp (Fig. 86) two- segmented, the first segment about twice as long as the second. Antennal toruli half closed when viewed from above, situated close together but widely spaced from the epistomal margin. Antenna (Fig. 88) much like that of the male described above, but the third funicular segment larger; the sensilla indistinct.

Thorax (Fig. 87) distinct from that of the smaller males by its shape: the pronotum tapering in front, its maximum width nearly one and a half times the length; the lateral sclerites (presumably representing the metanotum) rather small, and less elongate than in the other males. Wing remnant large, pubescent. Fore leg (Fig. 82) essentially similar to that of the male described above; the tarsal segments approximately in ratio 15 : 10 : 9 : 8 : 40. Mid leg (Fig. 83): the tibia has more antiaxial spines at the ventral angle, and the distal row of peg-like spines is less complete; the tarsal segments approximately in ratio 10 : 5 : 5: 4 : 24. Hind leg (Fig. 81): the apical armature of the tibia is reduced, the distal row consisting of a few scattered peg-like spines only; the tarsal segments ap- proximately in ratio 3 : 2 : 1 : 1 : 8.

Gaster. Genitalia, Fig. 89; the claspers bear three claws.

Length (head and thorax), 1.8 mm. Colour dark brown, the gastral tergites and sternites sclerotized, and distinctly darker than the connecting membranes.

Pronotum (Fig. 101) wide and very long, about as long as the head; the scutum almost half as long as the pronotum, with two long black hairs on the parapsides (as on the axillae), the parapsidal furrows more nearly complete than in any of the other Sycoryctini described in this paper, but obsolete in the posterior fifth; scutellum (Fig. 100) more angular than in Arachonia borneensis, but almost of the same size and structure, more like Sycoryctes Ailli in general outline but distinctly smaller; metanotum short, narrower than the propodeum. Propodeum rather long, with the usual ridges, and with long hairs posterior to the spiracular peritremata and along the lateral margins. Fore wing (5 : 2), 2.2 mm long; the submarginal, marginal, stigmal, and postmarginal veins approximately in ratio 16 : 18 : 7 : 18, the submarginal vein with two pustules, the stigmal with four in one row; the membrane moderately pubescent; the fringe of moderate length. Hind wing (3 : 1) rather broad, 1.2 mm long; the fringe long. Fore leg moderately pubescent on the antiaxial surfaces, subglabrous on the axial; with reticulate sculpturation; the coxa more than thrice as long as the trochanter, not much shorter than the femur; the tibia straight, its apical armature (Fig. 91—-92) consisting of two axial, dorsal, conical spines, one antiaxial, dorsal spine, and three peg-like spines close to the ventral spur, moreover, the dorso-apical angle is distinctly produced; the tarsus pentamerous, fimbriate along the plantar edge, hirsute, and provided with the usual spines, the segments approximately in ratio 7: 4:2 : 3 : 9.

Gaster. The ninth urotergite is more than three times as long as the body, the tip bears small pygostyles (Fig. 97).

Length (head and body up to and including the eighth abdominal segment), 2.8 mm. Colour almost uniform yellowish brown.

Remark. — This species differs from the species previously described in the genus Sycoscapteridea Ashmead, by several characters, some of which may be enumerated as follows. The antennal toruli are situated rather close to the epistomal

188 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 7, 1966

margin; there are three antennal ring-segments (versus one in the other species) ; the pronotum is particularly long; the ninth urotergite bears pygostyles. As JOSEPH (1953, 1957), in his descriptions of several species of Sycoscapteridea, evidently did not recognize the true morphological character of the “tail” of these insects, the pygostyles may have escaped his attention.

The type species of the genus Sycoscapteridea Ashmead, viz. S yeoscapier mont- lifer Westwood, is known in the male sex only.

Length (head, thorax, and gaster), approximately 3 mm. Colour black bronze, the legs except for the black coxae, yellowish; the palps of the mouth parts and the antennae infuscated; the compound eyes pinkish red.

Remark. — Grandiana corneliae, evidently related to Grandiana wassae Wiebes (1961 : 245—249, Fig. 1—19), may be distinguished in both male and female specimens by the more transverse head, the shape and pubescence of the antennal segments, and the greater number of tibial spines; the male, moreover, has two antennal ring-segments, versus one in G. wassae, and the toruli of the antennae are situated laterally, not ventrally; the postmarginal vein of the female fore wing is distinctly longer than in G. wassae.

The host of the present species, Ficus stupenda Miq. (subgenus Urostigma, section Conosycea) is only remotely related to that of G. wassae, Ficus wassae Roxb. (subgenus Ficus, section Sycidium).

NEW AND LITTLE KNOWN APHIDS FROM PAKISTAN (HOMOPTERA, APHIDIDAE)

BY

D. HILLE RIS LAMBERS Bladluisonderzoek T.N.O., Bennekom, Netherlands

ABSTRACT

In this paper the following new genera and species are described from Northern Pakistan.

Aphis longituba spec. nov., from unidentified herbaceous climber; Ceruraphis eastopi spec. nov., from Viburnum cotinifolium; Chaitophorus kapuri spec. nov., from Populus ciliata; Chaitophorus nigritus spec. nov., from Salix sp.; Chaitophorus pakistanicus spec. nov., from Salix acmophylla and S. tetrasperma; Cinara lachnirostris spec. nov., from Pinus (probably wallichiana); Cinara maculipes spec. nov., from Pinus wallichiana; Epipemphigus gen. nov., type-species Pemphigus imaicus Cholodkovsky, 1912; Globulicaudaphis gen. nov., type-species Globulicaudaphis pakistanica spec. nov., from Quercus (probably dilatata); Macrosiphum pachysiphon spec. nov., from Rubus lasiocarpus; Liosomaphis atra spec. nov., from Berberis sp.; Matsumuraja capitophoroides spec. nov., from Rubus lasiocarpus and Rubus sp.; Peri- phyllus vandenboschi spec. nov., from Acer sp.; Pseudessigella gen. nov., type-species Pseudessigella brachychaeta spec. nov., from Pinus wallichiana.

Some notes on the identity of Chaitophorus himalayensis (Das, 1918), often mistaken for C. pakistanicus spec. nov., are given. It is suggested that Hayhurstia tataricae Aizenberg, 1935, from Lonicera tatarica is a synonym of Brevicoryne coriandri Das, 1918, from Corian- drum, referred to Hyadaphis Kirkaldy, 1904, type-species Aphis xylostei Schrank, 1801, of which genus Neohayhurstia Aizenberg, 1954, type-species Hayhurstia tataricae Aizenberg, 1935, becomes a synonym. The fundatrix of Epipemphigus imaicus (Cholodkovsky, 1912) is described for the first time, and a key to the apterous females of Matsumuraja Schumacher, 1921, is given.

Introduction

Dr. R. VAN DEN BoscH, Berkeley, California, managed to collect, during a short stay in Northern West Pakistan, a considerable number of aphid samples which he most kindly gave to me for identification. Where not otherwise indicated, all the material originates from this collector. Several undescribed species which were already familiar to me from material received from my colleagues Mr. A. N. Basu and Mr. K. D. VERMA, will later be described by them. Other species are described here, partly also from material received for identification from the Commonwealth Institute for Biological Control.

Types of new species are in the author’s collection, with the exception of those of Ceruraphis eastopi spec. nov.

Aphis longituba spec. nov.

Apterous viviparous female. In life pale green, mottled with darker green on abdomen; appendages pale

except siphunculi which are black-tipped. In mounted specimens body oval, about 1.3—1.6 mm long. Tergum completely unpigmented. Extremely small marginal tubercles present, on abdominal segment I, where they are but little wider in diameter than the papilla of a marginal hair but rather taller than their basal width, and on segment VII, where they are a little wider than the porus of the nearest stigma. Dorsal hairs scarce, those on abdominal tergite III about 0.016—0.025 mm long, stiff, subacute, but the 2 hairs on tergite VIII up to 0.060 mm long; marginal hairs on tergites II—IV usually in double pairs, sometimes in a single pair on tergite III. Front slightly sinuated. Antennae pale with the processus terminalis faintly smoky; flagellum imbricated; processus terminalis at most as long as segment III, usually shorter, 2—21/, times base of segment VI; hairs on segment III scarce (e.g. 7 or 9), half as long as basal diameter of the segment. Rostrum just reaching the hind coxae; last segment rather long, about 11/;—11/, times as long as second joint of hind tarsi, with 2, more rarely 3 hairs besides the 3 subapical pairs. Siphunculi quite pale with apical 1/g—1/g blackish, gradually tapering from base to apex, in the middle about 11/, times as wide, at apex about as wide as the hind tibiae, imbricated, with rather small flange, about 1/;—2/, of length of body, 22/3—31/, times as long as cauda. Cauda small, at base about twice as wide as middle of siphunculi, more or less like that of Aphis gossypii Glover, cylindrical to tapering with rounded top, with 5—6 hairs. Legs rather long, pale with brownish tarsi; trochanter and femora on the underside with at least a few hairs fine and long, longer than the basal width of a femur; tibial hairs rather like those of A. gossypii, short; first tarsal joints with 3, 3, 2 hairs, second joints markedly imbricated.

Discussion. This Aphis was collected from the curled tender tips (undersides) of a vine-like herbaceous plant. Species of the genus with such long, slender siphunculi that are pale are scarce, and I know of no other than A. farinosa Gmelin, very different as to marginal tubercles, and A. sdaez v. d. Goot which has much thinner siphunculi. Some species of the group infesting Ribes and Ona- graceae have such long pale siphunculi, but these always have more than 3 hairs on the basal half of the last rostral segment and longer antennal hairs. The long pale siphunculi with their Sonspicuously -dark.tips, and the small cauda, together

with the scarcity of marginal tubercles and the few rostral hairs make recognition of the species within the very large genus Aphis L. quite easy.

Types. Holotype: apterous viviparous female (measurements no. 1), from an unidentified plant, Murree, West Pakistan, 3.VII.1964 (R. VAN DEN Bosch), P-VII-3a. Paratypes: 6 apterae viviparae with data as for the holotype.

Ceruraphis eastopi spec. nov. (Fig. 1—2, p. 208)

Alate viviparous female.

Colour in life not known. In mounted specimens body about 2.70—3.15 mm long, elongated. Head and thorax blackish sclerotic; abdomen with extensive darkish dorsal sclerotisation consisting of thick spino-pleural bars which are mutually free on tergites I and II, but except medially sometimes almost com- pletely fused on tergites III—VI. Marginal tubercles variable, sometimes on all segments from I—VII, but always on II—IV, low, flat, on segments II—IV about 0.015 mm in diameter. Spinal tubercles very small, very irregularly present on tergites I—VIII, mesonotum or vertex. Dorsal hairs fine, on tergite II} up to 0.045 mm long; tergite IV with mostly single spinal and pleural pairs, but with up to 8 marginal pairs, on more anterior tergites usually with several additional spinal and pleural hairs; tergite VIII with 4—5 hairs. Posterior row of 6—8 hairs on vertex remarkably far from posterior margin of head. Front sinuated. Antennae blackish, about 3/, of length of body; segment III on basal one-third distinctly imbricated, with about 15—23 rather protruding, mostly large and partly markedly transversely oval rhinaria over whole length; segment IV with 1—5, rarely without such rhinaria; segment V rarely with a secondary rhinarium, but with an enormous primary rhinarium of about 0.10 mm long and 0.035 mm wide (Fig. 1), covering up to half the length of the segment; segment VI with a hardly smaller primary rhinarium, which covers much more than half the basal portion of the segment; hairs on segment III rather bent and adpressed, up to just longer than basal diameter of the segment. Rostrum reaching to half way the middle coxae; last segment rather elongated, about 10/,, of second joint of hind tarsi, with 2 hairs besides the 3 subapical pairs. Siphunculi tapering from base to apex or slightly constricted at base, dark, about 1/,, of length of body, in the middle 11/,)— 11/, times as thick as middle portion of hind tibiae, dorsally from base to apex with a few wavy transverse lines of bluntish spinules, ventrally with very dis- persed imbrications bearing few blunt spinules, and these imbrications near apex running together to form cells (Fig. 2); flange hardly indicated. Cauda 2/3—4/5 of siphunculi, dark, triangular with convex sides, rather acute, with 5 hairs. Legs rather long; femora blackish with pale base; tibiae dark with blackish base and apex; the hind tibiae over most of their length, the other tibiae near base, with a very curious, vague, wavy transverse striation similar to that on distal two-thirds of antennal segment III; first tarsal joints with 3, 3, 2 hairs. Venation of wings normal; subcostal vein system and pterostigma conspicuously pale.

Larvae.

Embryos in alatae. Antennae of 4? segments; processus terminalis (fully stretched) only 1.4 times base of last segment; base with one stout and one small hair; penultimate segment with two stout, and one small hair, last rostral segment 0.065, with two hairs besides the 3 subapical pairs.

Alatoid nymphs, last instar. On abdomen with small dark marginal sclerites bearing mostly 1 or 2 hairs and a tubercle. Spinally especially on the posterior tergites, from IV or V caudad, with very small, caudad much larger sclerites bearing one hair each, and besides, especially on tergites VII and VIII, a spinal tubercle; all tubercles more pronounced, and larger than in most adults. Primary rhinaria on antennal segments V and VI round, ciliate, rather large, about 0.025— 0.035 mm across the rims. Hind tibiae without spinules. As in other species of the genus there is an unusually large distance between the first and the second pair of coxae.

Discussion. The eight alatae that were collected evidently were not gynoparae returned from their secondary host plant, for the same sample contained a number of almost mature alatoid nymphs. Therefore the specimens must have developed on Viburnum. Notwithstanding the date of collecting, the fact that only alatae, and only alatoid nymphs were found, seems to suggest host alternation. Perhaps the specimens were leaving Viburnum for a secondary host plant. In other species of the genus the host plants are Cyperaceae, rarely Juncaceae. Indeed Dr. REMAU- DIERE has collected a Ceruraphis on some species of Carex in Iran which might be this species, but the alatae lack the gigantic primary rhinaria of C. eastopr.

These rhinaria make recognition of the described morph very easy, for to my knowledge no other member of this subfamily with such primary rhinaria has been described. However, almost certainly other morphs do not have such unusual rhinaria: in the alatoid nymphs the primary rhinaria are of ordinary shape. The sculpture of the siphunculi may be useful for identifying the other morphs when these are found.

The very short processus terminalis in the embryos inside the described alatae suggests that in apterae the processus terminalis 1s much shorter than in the described alatae. When the apterae are found they could be identified by the curious mixture of short and long hairs on the last two antennal segments of the embryos that they contain.

D. Hie Ris LAMBERS: Aphids from Pakistan 197

The species is named after Dr. V. F. Easrop, British Museum (Natural History), London.

Types. Holotype: alate viviparous female (measurements no. 1), from Viburnum cotinifolium, Otrore, West Pakistan, 12.IX.1962 (Commonwealth Inst. Biol. Control, C.I.E. no. 18753: 847). Paratypes: 7 alatae and 7 alatoid nymphs with data as for the holotype. The holotype and all but two alate paratypes are in the British Museum (Natural History), London.

Chaitophorus himalayensis (Das, 1918)

Das (1918) mentions in his description of Eichochaitophorus himalayensis that the siphunculi in the apterae viviparae are brown. The processus terminalis is about 21/ times as long as the base of antennal segment VI. These characters do not apply to material identified by TAKAHASHI and recorded by him from Siam, and to other specimens identified as himalayensis Das, from Pakistan and India.

Material of a species from Salix from India agrees with the description of hima- layensis by Das in the pigmentation of the siphunculi and the length of the processus terminalis. The first tarsal joints of the apterae viviparae have 7 hairs, and the abdominal dorsum is distinctly nodulose.

Chaitophorus kapuri spec. nov.

Apterous viviparous female.

Colour in life not noted, but presumably largely blackish. Mounted specimens dorsally dark to blackish sclerotic with the head laterally, and a not sharply bordered median area from metanotum to about tergite III distinctly paler to pale. Abdominal tergites I—VI solidly fused, the other tergites mutually free. Dorsum not smooth but rather evenly covered with mostly irregularly arranged, not joined, semiobtuse to blunt spinules which in lateral view are little more than half as high as their basal width; locally these spinules are arranged in wavy transverse lines. Dorsal hairs acute or somewhat acuminate, stiff, not wavy; the longest spinal hairs on abdominal tergite III up to 6 times basal diameter of antennal segment III. Antennae about 5/7,—2/3 of length of body, with segment I and the part near the rhinaria on segment VI dusky to dark, the rest quite pale, slightly imbricated; segment III with on inner side 2—4 hairs of about 3—33/, times basal diameter of the segment, and with some much shorter hairs rather similar to those on outer side which are about as long as basal diameter of the segment; base of segment VI with 2—3 hairs, the longest of which is 12/,—2 times the shortest; for inter- relation of antennal segments vide measurements. Last rostral segment about as long as second joint of hind tarsi, with 2—4 hairs besides the 3 subapical pairs. Siphunculi very short, blackish, not surrounded by a membranous ring, with 3—4 rows of transverse reticulations apically that are only well visible in lateral view. Cauda rather pale, distinctly knobbed, with the knob usually wider than long. Legs completely pale with only the apices of the tarsi slightly dusky; tibiae with a few short spinules at the very tip; first tarsal joints with 7, 7, 7 hairs; empodial hairs ribbon-shaped.

Alate viviparous female.

Colour in life not noted. Mounted specimens with black head and thorax, with on the abdominal dorsum thick spino-pleural, blackish, transverse bars from seg- ment II or HI to VIII, which bars tend to fuse to a central sclerite from tergites III to VI; marginal abdominal sclerites blackish, on segments II—V each with 6—11 hairs and on the posterior part with a very slender tubercle that often looks like the socket of a large hair with the shaft broken near the base. Antennae 3/4—5/ of the length of body, pigmented as in apterae, but with also the apex of segment V somewhat darkened; hairs on inner side of segment III considerably shorter than in apterae, but still up to 31/, times as long as basal diameter of segment III because the latter is constricted at base; segment III with about 10—12 rather large rhinaria more or less in a row over the length of the segment. Siphun- culi conical, nearly as long as their basal width, dark, with 3—4 rows of basad transverse reticulations. Legs pallid as in apterae. Wings with normal venation, the veins very conspicuously and rather broadly darkly bordered.

Tergum with very small bluntish nodules that are joined to wavy lines that mostly medially run more or less parallel, with on the thorax here and there a faint tendency to reticulation. Dorsal hairs slightly flexed, with fine apices; the longest spinal hairs on abdominal tergite III about 5 times as long as basal diameter of antennal segment III. Antennae pale with segment I, the distal half of the processus terminalis and sometimes the area near the rhinaria on the last segment dusky to dark, sometimes on one side of 5 segments, 1/,— 5/g of the length of body; segment III on inner side with 3—6 hairs of up to 21/9—3 times basal diameter of the segment and with some shorter ones that yet are 11/, times or more times that diameter and considerably longer than those ori outer side which are mostly shorter than that diameter; the longest of the 2, rarely 3 hairs on the base of the last segment 21/,—3 times as long as the shortest. Last rostral segment very nearly as long as second joint of hind tarsi, with 2 hairs besides the 3 subapical pairs; one pair of the latter placed very far basad. Siphun- culi black, surrounded by a membranous area, more or less conical, distinctly reticulated on distal half. Cauda knobbed, pale with dusky knob, the latter wider than long. Legs pale with the tarsi wholly or distally dusky; tibiae only at the very apex with some spinules; first tarsal joints with 5 hairs; empodial hairs setaceous, blunt to acute.

200 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 8, 1966

Larvae. From birth with black scleroites to the bases of the dorsal hairs.

Discussion. According to its collector the aphids live most characteristically in tight colonies around galls on the leaves of Salix sp. No data on myrmecophily are available.

In structure and ornamentation of the dorsum this species strongly resembles Chaitophorus salicti (Schrank, 1801), but it can at once be distinguished by the membranous ring around the siphunculi, the shorter, less hairy last rostral seg- ment and unpigmented legs in, otherwise, solidly black specimens.

Types. Holotype: apterous viviparous female (measurements no. 1), from Salix sp., Murree (7500 ft), West Pakistan, 27.VI.1964. Paratypes: apterae viviparae with the same collecting data.

Chaitophorus pakistanicus spec. nov.

Apterous viviparous female. :

Colour in life not known, but almost certainly greenish or yellowish. Mounted specimens completely pale. Integumentum dorsally virtually smooth. Dorsal hairs variable in length, stiff, mostly rather thick, the marginal ones acute, the rest rarely partly acute, normally either partly acuminate or all with furcated apices; longest spinal hairs on abdominal tergite III from 3—51/, times basal diameter of an- tennal segment III. Antennae 4/,—5/, of length of body, always with the area near the rhinaria on segment VI and the apical half of the processus terminalis dark or dusky, sometimes with segment I, the apex of segment V, and the whole segment VI, dusky; base of segment III slightly attenuated; that segment on inner side with 2—5 rather stiff hairs with bluntish apices that are 11/,—2 times basal diameter of the segment, often hardly longer than some hairs on the outer side; basal part of segment VI with 2 rather short hairs of about equal length; processus terminalis 13/„—21/, times base of last segment. Last rostral segment only 3/4— 5/4 of second joint of hind tarsi, with 2 long hairs as long as the longest of the 3 subapical pairs; of the latter one pair placed far basad. Siphunculi not pigmented, very small, truncated conical or cylindrical, with only 2—3 rows of transverse reticulation at apex. Cauda pale, knobbed, the knob broader than long. Legs pale with dusky second tarsal joints; tibiae smooth, in some of the specimens from Kashmir with a few pseudosensoria; first tarsal joints with 5 hairs; empodial hairs thinly setaceous.

Larvae. Dorsal hairs without pigmented sclerites at their bases. First two antennal seg- ments often brownish.

Discussion. The few records published after that of Das (1918) of Chaito- phorus himalayensis (Das) probably relate to the present species, which in many respects agrees with the description by that author, except for its pale siphunculi and shorter processus terminalis. Specimens from Salix, Chiengmai, Thailand, 5.V.1940, received from Dr. TAKAHASHI and identified and recorded by him as Chaitophorus himalayensis (Das) differ slightly from the material described above by having a few more hairs on antennal segment III.

In a number of characters the new species agrees with colourless specimens of Chaitophorus salicti (Schrank), but the short last rostral segment and almost smooth abdominal tergum, as well as the short processus terminalis make recog- nition easy.

No trace of a mesosternal processus present. Siphuncular cones quite small, often in- conspicuous, in diameter just smaller than the length of rostral segment IV, with only about 25 hairs of the ventral type. Cauda normal. Legs rather thick, with the femora dark to blackish brown with the very base pale, tibiae with dark bases and apices, on the fore and middle legs the middle part brownish yellow, on the hind tibiae somewhat paler just past the base, but the rest gradually darker towards apex; hairs on basal half of hind tibiae stiff and acuminate, considerably shorter than width of tibiae; first tarsal joints with very numerous hairs and two short spines, ventrally about 12/3 times as long as dorsally, 5 times as long as the width at the basal articulation; empodial hairs just over half as long as the sclerite on which they are placed.

Epipemphigus gen. nov.

Fundatrix with four to five segmented antennae, without wax glands, without siphunculi, with 2—3 caudal hairs, with the empodial hairs very short, about 1/4—1/3 of the length of the claws; embryos inside fundatrices also with short empodial hairs, with wax glands. Alatae of the second generation both as larvae

D. Hire Ris LAMBERS : Aphids from Pakistan 205

and as adults with minute, unpigmented and therefore nearly invisible siphunculi,

perhaps not always, with simple media in the fore wings, with very distinctly

ciliate secondary rhinaria, with very irregular chaetotaxy of the first tarsal joints

(e.g. 4 ‚4, 4; 4, 2, 4; 4, 2, 2, etc.); embryos inside these alatae with mouth parts,

and with the empodial hairs at most 1/3 of the length of the claws. Type-species: Pemphigus imaicus Cholodkovsky, 1912.

Discussion. BORNER’s (1952) subdivision of Pemphigine genera has the at- traction of being very simple. By considering the lengths of the empodial hairs in new born offspring of fundatrigeniae (alatae of the second generation) he discerns two groups, those with short empodial hairs, the Pemphigini, and those with long empodial hairs, the Pachypappini. In BORNER & HEINZE (1957) one finds in addition that in Pemphigini the fundatrix and adult fundatrigeniae have long empodial hairs.

A check on empodial hairs in embryos of viviparae showed that the American Paraprociphilus Mordv. from Acer and Alnus indeed have the required very long empodial hairs, and that the Asiatic Pemphigus baicalensis Chol. is, like Morp- VILKO (1929, 1935) suggested, a true Paraprociphilus. However, Paraprociphilus ucrainensis Mamontova, 1955, by the same standards is not a Paraprociphilus and, since KRZYWIEC (1962) showed that Mimeuria ulmiphila del Guercio is the same animal, this species should be placed not in Paraprociphilus Mordvilko, 1924, but in Mzmeuria Börner, 1952.

The new genus unites a number of important characters of BORNER’s Pachy- pappini with some characters of his Pemphigini. The fundatrix has no wax glands, which is typical for Pachypappa Koch and Aszphum Koch, but it has short em- podial hairs. The embryos in fundatrigeniae have short empodial hairs, a character of Pemphigini, but also the fundatrix and fundatrigeniae have these short empo- dial hairs which as Pemphigini they should not have. The very markedly ciliate secondary rhinaria resemble to some extent the rhinaria with nodules, spinules or minute ciliae in some Prociphilus Koch and Stagona Koch, but again these taxa have embryos with long empodial hairs. Therefore there is no alternative but erecting a new genus for Pemphigus imaicus Chol. The species is here redescribed.

Epipemphigus imaicus (Cholodkovsky, 1912)

Fundatrix.

Colour in life unknown. In mounted specimens body oval-rounded, about 2.0—2.25 mm long. Head and sides of prothorax blackish sclerotic; the rest colourless and membranous, but stigmal plates, subanal plate and subgenital plate brown and the sockets of the dorsal hairs somewhat pigmented. No wax glands present. Dorsal hairs numerous, with long hairs of about 0.070—0.085 mm regularly arranged, but besides a great number of scattered shorter and thinner hairs of 0.040—0.070 mm long; the long hairs rather stout at base, but the apices of all hairs drawn out into very fine apices; the sockets of especially the long hairs distinctly pigmented; tergites VII and VIII both only with 4 long hairs of 0.08— 0.11 mm long. Antennae as dark as the head, 1/,—1/, of length of body, of

Alate viviparous female (emigrant).

Colour in life not known. In mounted specimens head and thorax black but a triangular median part on the mesonotum paler to pale; abdomen without local sclerotisation. No wax glands present on head and thorax, but abdomen with small wax glands as follows: marginal ones on segments I—VII; no pleural ones; spinal ones, mostly strongly transverse, fragmented or consisting only of a few cells on tergites I—VI, irregularly present on most of these segments, and rarely also (a few cells only) on tergite VIII. Dorsal hairs inconspicuous, mostly not placed on the wax glands but quite near them, rather short, about 0.020 mm long. Antennae of 6 segments, about 11/,—2 times as long as width of head through the eyes, 2/,—1/. of length of body; segment III the longest, with 4—9 rather irregular very narrow rhinaria with wide rims on which rather long, very fine ciliae are implanted; IV with 2—5 rhinaria; V with 0—1, more rarely 2 secondary rhinaria and a primary rhinarium of very irregular shape, encircling about 2/3— 3/4 of the circumference of the segment and covering, measured through the outer rim, about 2/, of its length, with little islands or peninsulae sticking out from the margin; segment VI without secondary rhinaria, with a primary rhinarium of

much the same shape and size as, or larger than that on segment V; these primary rhinaria with long, often furcated ciliae, and on the peninsulae sometimes with tree-shaped, many-branched ciliae; processus terminalis markedly thinner at base than in the middle, with 8—10 hairs near apex. Rostrum short, reaching to half- way the middle coxae; last segment acute, conical with slightly convex sides, just less than half as long as second joint of hind tarsi, with only the 3 subapical pairs of hairs. Siphunculi perhaps sometimes present, but not pigmented and so un- developed that only irregularities in the microstructure indicate their presence. Cauda undeveloped, broad, with 2, sometimes 3 hairs. Legs dark to blackish, slender; the terminal spines of the tibiae not much different from the other hairs near their apex; first tarsal joints with 2—4 hairs, rarely with the same number on all legs, and with spinules; second tarsal joints with transverse lines of spinules, with about 5 pairs of ventral hairs; empodial hairs just less than half as long as the claws. Fore wings with simple media; the veins not bordered.

Embryos in emigrants.

Antennae of 4 segments; primary rhinaria both transversely oval, twice as long as wide, that on IV twice as large as that on III; processus terminalis with 5 hairs. Wax glands very large, more or less rectangular with rounded angles, in the transverse rows (of probably 4 per segment) at only about 0.004—0.006 mm from each other, each with a hair. Empodial hairs about 1/3—2/; of the length of the claws.

Discussion. CHOLODKOVSKY (1912) gave with the original description a drawing of the emigrants’ antennae with their curious primary rhinaria, after material from Dehra-Dun, India. He writes that all the rhinaria are ciliate, but this has apparently escaped the notice of later authors. The gall which he also illustrates resembles that made by Pemphigus populinigrae Schrank on Populus nigra, irregularly sausage-like on the upperside of the leaf along the mid vein.

Wings with normal venation. Siphunculi truncated-conical, fused with the marginal sclerite of tergite VI which bears 2—3 hairs. Cauda not knobbed but consisting of a large smooth membranous colourless bladder on the underside of which a pale, sclerotic, transversely oval, spinulose part with hairs is present. Subanal plate with two widely separated large lobes. Two rudimentary gonaphyses. Subgenital plate not pigmented, normal. First tarsal joints with 2 dorsal and 5 ventral hairs.

First instar larvae with only single pairs of spinal and marginal long knobbed hairs on abdomen, placed singly on dark sclerites. Antennae of 4 segments with

Discussion. The genus differs from all described aphids by the structure of its anal tergite. There is a considerable resemblance in the sclerotic pattern to that of Hoplochaetaphis Aizenberg, 1959, but there the similarity ends. Myzocallis Pas- serini, 1860, is nearly related, and structurally quite close, but it may be separated at once by the caudal structure.

Apterous viviparous female.

Colour in life “basically pale greenish marked with a darker olive green dorsal pattern and with what appears to be white paired waxy markings running laterally from the head about 2/3 the length of body. Legs pale with black knees, antennae pale, annulated with dark markings at joints”. In mounted specimens (Pl. 2) anterior part of head pale, posterior middle part with a dark smoky area that is partly fused with a similarly pigmented square spinal area on the pronotum, divided in two by a fine membranous suture with halfway a transverse rhomboidal membranous hole; from mesonotum to abdominal tergite IV each segment with a spinal pair of rectangular to square, dark sclerites spinally separated by narrow membranous sutures, but on tergite IV with their posterior halves fused; similar marginal sclerites present on abdominal segments I—III, but segment IV with only the posterior halves of such sclerites; occasionally a few very small round pleural sclerites present on tergites I—IV; on tergite V an irregularly shaped spino-marginal transverse bar which is not connected with the siphunculi; tergites VI and VII with pairs of transverse spinal sclerites and traces of marginal sclerites; tergite VIII with a sclerotic transverse bar; the sclerites from mesonotum caudad slightly darker than those more cephalad, all with the margins darker than the centres. Dorsal hairs rather long, straight, up to 4 times as long as basal diameter of antennal segment III, with slightly widened blunt or knobbed apex, on moderate sockets; the mentioned spinal sclerites on mesonotum each with 3 hairs, from metanotum to tergite IV with 2 hairs, on tergites VI and VII mostly with 2, sometimes with 1 hair; marginal sclerites with 2 or 3 hairs; bar across tergite V with 18—24 hairs; tergite VIII with 8 hairs that may be up to 61/, times the mentioned diameter; pleural hairs irregularly present on tergites I—IV. Ventral hairs fine, acute and inconspicuous, mostly shorter than the mentioned diameter. Head normal, Myzocallis-like; antennae subequal in length to body, very pale with the apices of all segments but II, blackish; no rhinaria on segment III; hairs on inner side of segments I and II similar to those on vertex, but shorter; those on inner side of segment III still capitate but small and just shorter than basal dia- meter of the segment. Rostrum reaching to middle coxae; last segment rather short, subequal to second joint of hind tarsi, with 4—6 hairs besides the 3 sub- apical pairs. Siphunculi truncated-conical, as dark as the dorsal sclerites, with paler

base, approximately smooth, caudad fused with the marginal sclerite of tergite VI, that bears 2—3 hairs. Cauda, if it shrinks in mounts (Fig. 3), seemingly semi- circular with all the 8—12 hairs on the underside; if it does not shrink, cauda globular and the hairs ventrally on basal half. Subanal plate bilobed, the lobes at their bases far apart, curved inwards apicad. Two rudimentary gonapophyses. Legs quite pale with a dark smoky band around each femur a little basad the tip; tibiae spinulose near the tips, the hind tibiae spinulose over distal 1/3 part; first tarsal joints ventrally with 5 hairs, dorsally with 2; empodial hairs strongly enlarged, flat.

Discussion. According to the collector, Dr. R. VAN DEN Boscu, the species lives in colonies on the undersides of its host plant, Quercus dilatata? No ants were attending the aphids.

The species, apart from its cauda and the rather unusual abdominal sclerotisa- tion, looks like a rather normal Myzocallis. In larvae the cauda has an almost normal appearance, but even in the first instar the two hairs on the cauda are distinctly on the underside, while in later instars the hairs seem to recede on the underside, because the upperside, almost invisible in dorsal view, protrudes more and more. During mounting the very thin upperside collapses. Afterwards the cauda in dorsal view looks semicircular and rather normal because the upperside is so transparent that the ventral, almost basal, position of the caudal hairs can hardly be detected.

Types. Holotype: apterous viviparous female (measurements no. 1), from Quercus dilatata?, Murree (7000 ft), 30.VI.1964 (R. VAN DEN BoscH), P-30a. Paratypes: 11 apterae and one alata with collecting data as for holotype.

Hyadaphis coriandri (Das, 1918) and H. tataricae (Aizenberg, 1935).

A large sample of a small Hyadaphis collected near Murree (7500 ft), West Pakistan, 3.VII.1964, led to a closer study of the above two species. The resem- blance between material of coriandri from various Umbelliferae from India to East Africa, and three samples of apterous tatartcae from Lonicera tatarica from Russia and Poland is so great that they would seem to belong to the same species. The only difference that I could find is in the shape of the siphunculi which in apterous specimens from Umbelliferae usually slightly taper from the base over two-thirds of their length, while in my few specimens from Lonicera from Poland and Russia they tend to be wider in the middle than at their basal one-third part. In the Pakistan apterae the siphunculi are almost as in apterae from Umbelliferae, but the cauda is less thick, while in the alatae the rhinaria are more tuberculate and slightly larger than in alatae from Umbelliferae.

These facts suggest that, like foeniculi Pass., H. coriandri (Das) is a host alternating species, with Lonicera tatarica and probably other species of Lonicera (in the case of the Pakistan material a climbing one) as primary host plants, and various Umbelliferae as summer hosts. Hayhurstia tataricae Aizenberg, 1935, type- species of Neohayhurstia Aizenberg, 1954, appears to be a synonym of Brevicoryne coriandri Das, 1918, referred to Hyadaphis Kirkaldy, 1904. Other synonyms (Hire Ris LAMBERS, 1948) are Hyalopterus obscurus Theobald, 1922, Hya- daphis conica Borner, 1932, and Hyalopterus peucedani Hall, 1932, and according to EASTOP (1958) also Hyalopterus carii Theobald, 1929, and probably Hyalo- pterus albus Monzen, 1929.

Liosomaphis atra spec. nov.

Apterous viviparous female. In life dark purplish brown except centre of abdominal dorsum which is almost dirty greenish; legs and antennae pale, siphunculi dark on distal half. In mounted

219 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 8, 1966

specimens body shortly oval, about 1.30—1.60 mm long. Tergum blackish sclerotic with abdominal tergites I—VI solidly fused to a shield, which like the head, thoracic segments, and abdominal tergites VII and VIII is strongly wrinkled; the middle anterior part of the abdominal shield is often paler. Siphuncular base sur- rounded by a rather large membranous colourless area. Marginal tubercles ap- parently absent. Dorsal hairs short, subacute, on abdominal tergite III about half as long as basal diameter of antennal segment III, the 2 hairs on tergite VIII not much longer. Front with the broad, almost straight, middle part projecting beyond the insignificant frontal tubercles. Antennae pale with dark basal segments and somewhat dusky apex, about half as long as body; hairs on segment III about 1/3—2/; of basal diameter of the segment. Rostrum long for the genus, reaching to or past the third pair of coxae; last segment about 9/, of second joint of hind tarsi, with 2 hairs besides the 3 subapical pairs. Siphunculi rather evenly pale, to dusky with pale base, about 1/, of length of body, twice the length of the cauda, with basal 2/,—1/. consisting of an almost cylindrical stem which is 11/4 times as thick as the hind tibiae; from the stem they abruptly increase in width to the middle of their length, to a maximum of about twice the width of the stem from where they more gradually decrease in width to the small flange where they are as thick as the hind tibiae; most of the swelling is, as usual, on the inner side; surface quite smooth with only at the very apex some transverse striae. Cauda cylindrical, or near base constricted, with distal half to one-third part tapering to the semiobtuse apex, of the colour of the distal part of the siphunculi, with 5 hairs. Legs pale to evenly pale brownish yellow; first tarsal joints with 3, 3, 3 hairs.

Discussion. Recently some more Liosomaphis species have been described from Asia (L. lydiae Narzykulov, 1957, later made the type of Berberidaphis Narzy- kulov, 1960; L. twranicus Narzykulov, 1960; and L. himalayensis Basu, 1964); all are pale insects, without strong sclerotisation of the dorsum. As to structure of siphunculi and cauda our species most strongly resembles L. twranicus Narzykulov, also in the length of the processus terminalis. In L. himalayensis the antennae and the processus terminalis are absolutely and relatively longer. The rostrum of our new species is conspicuously longer than that in the other species in which it barely reaches past the middle coxae.

Macrosiphum pachysiphon spec. nov.

Apterous viviparous female.

In life very pale pink with black siphunculi. In mounted specimens body about 3.0—3.5 mm long. Tergum membranous and almost colourless with the exception of vague smoky roundish pleural intersegmental sclerites on abdomen and hardly more distinct antesiphuncular sclerites, but without marginal or postsiphuncular sclerites. Dorsal hairs numerous and conspicuous, stiff, blunt, on tergite HI about 11/,—11/, times as long as basal diameter of antennal segment III; marginal hairs quite numerous, tergite III often with 7—9 hairs on each side, tergite VIII with 8—10 hairs. Marginal tubercles small and flat, rather regularly present on tergites II—IV. Frontal tubercles strongly diverging, little developed; depth of frontal furrow only about 1/,—2/,, of the distance between the antennal bases, with flat to concave bottom; each frontal tubercle with 5—8 hairs, nearly all on the underside. Antennae pale with apex of segment III dusky, that of IV and V dark brownish black and the whole of VI blackish, about 7/g—1 times length of body; IIIrd segment smooth with the very base imbricated, with 2—7 (average of 26 antennae: 4.0) curiously sunk rhinaria on slightly elevated parts of the segment near its base, and with numerous, some 30, hairs the longest of which are as long as basal diameter of the segment; processus terminalis 41/3—5 times length of base of last segment. Rostrum reaching just past the middle coxae; last segment as in many Sztobion spp. somewhat constricted at base, not very blunt, rather short, about 2/3 of second hind tarsal joint, with 4—7 hairs besides the 3 subapical pairs.

Alate viviparous female.

Colour in life not known, but abdomen presumably as in apterae. In mounted specimens head and thorax brownish, the abdomen with an elaborate, smoky sclerotic pattern, consisting of irregularly fragmented spinal sclerites, bearing 1—3 hairs each, very small pleural sclerites, rather large transverse pleural inter- segmental sclerites and squarish marginal sclerites with many hairs. Antennae with the basal segments and the very base of segment III brownish like the head, the rest dark to black, but segment III usually distinctly blacker than segments IV and V; segment III with about 20—30 rhinaria that are larger and less sunken than in apterae, along one side of the segment, in irregular arrangement on basal half but in single file on distal half. Siphunculi more cylindrical and thinner than in apterae with distal 1/, part reticulated. Cauda thinner and more acute than in apterae. Legs with the femora blackish brown with pale base, tibiae brownish yellow with blackish apices. Wings with normal venation, but stigma elongated and the same dark or blackish colour as the subcostal vein system, so that the wings seem to have an anterior dark margin. Other characters more or less as in apterae viviparae.

Discussion. According to Dr. R. VAN DEN BOSCH, who collected the Pakistan material, this aphid lives in tight colonies on the tender canes of the host plant. His sample consisted of apterae with two alatae, presumably of the second generation, but the sample from Assam consisted mainly of alatae with a few damaged apterae, of which unfortunately the date of collecting was not given.

In many respects this species resembles a Sztobion, e.g. by the last rostral seg- ment, the black siphunculi, the sclerotic pattern of the abdomen in alatae, etc. But the long and very numerous hairs on body and antennae make it impossible to place it in Sitobion Mordv. The very pale integumentum of apterae with which the very thick black siphunculi strongly contrast distinguish the species from all known relatives. Alatae can easily be recognized by their very dark subcostal vein system and blackish pterostigma.

Matsumuraja capitophoroides spec. nov.

Apterous viviparous female.

In life pale yellow with only the apices of antennal segments III—V, the part near the primary rhinaria on VI, and the distal part of the processus terminalis dark to blackish. In mounted specimens body elongated oval, very variable in length, from 1.30 to 2.25 mm long. Tergum colourless, not visibly sclerotic but actually thickened and marginally with semiglobular papillae which in dorsal view look like small thick round to oval rings. Dorsal hairs thick (0.005 mm) and stiff, rather variable in length, so that the spinal hairs on abdominal tergite III are about 0.035 mm, the pleural hairs, if present, 0.030 mm, the hairs on tergite VIII about 0.065 mm; in large specimens (second generation) pleural hairs often all present from tergite I to VI, appearing as duplicated spinal hairs, but in small specimens sometimes nearly all pleural hairs absent; marginal hairs in single pairs on each of the anterior abdominal segments, similar to the spinal hairs; all dorsal hairs distinctly knobbed, placed on strong conical sockets which are on top of short processes which, including the socket, in the case of spinal hairs are about as long as the hair on top. Head, except on the middle of vertex, quite rough by small spinules, with markedly diverging frontal tubercles; depth of frontal furrow about 1/, of the distance between the antennae; numerous capitate hairs on strong sockets present on upper and under side of the head, also on the front and on the inner and under side of the frontal tubercles. Antennae 2/3—7/,9 of length of body, pale with pigmentation as in the living insect; first segment on inner side with a sausage-shaped, quite blunt processus about as long as the segment, bearing 2—3 knobbed hairs; flagellum lightly imbricated; segment III with a few rather thin knobbed hairs of various length, the thickest of which are about 3/7 of the diameter of the segment at its widened very base. Rostrum reaching just past the middle coxae; last segment with almost straight, sometimes just concave sides, just swollen near apex, and therefore not acute, about as long as second joint of hind tarsi, with 2 hairs besides the 3 subapical pairs, one of which is placed far basad. Siphunculi pale with only the very apex dusky, about 1/,—2/, of length of body, lightly bluntly imbricated from base, but apical 1/7 part smooth, cylindrical and about 11/, times as thick as the hind tibiae, to just swollen on distal half where the diameter may be up to 11/, times the smallest on basal half, slightly attenu- ated (9/, 9 of minimum width on basal half) just below the small flange, 3— 31/, times as long as the cauda. Cauda pale, bluntly triangular with slightly con- vex sides, with 4 hairs. Legs rather long, pale with dusky tarsi; first tarsal joints with 3, 3, 2 hairs.

(1—2, from Rubus sp., Murree (7500 ft), West Pakistan, 5.VII.1964; 3—4 as 1—2, but 27.VI.1964).

Discussion. According to Dr. R. VAN DEN BOSCH this species lives in often large colonies on the underside of the leaves of its host plant, a Rxbs species that apparently also serves as host to Macrosiphum pachysiphon spec. nov., of which a sample was received from Rubus lasiocarpus. It would seem that this species does not have host alternation as suggested by TAKAHASHI (1959) for Matsumu- raja rubifoliae Tak. The sample collected by Dr. VAN DEN BoscH on 30.VI on Rubus consisted of apterae with one alatoid nymph. In a species with host alternation such a composition of the population on its secondary host would seem unlikely in that area at that time, because many other aphid species were only in their second generation. From samples received from other sources it appears that the species is widely distributed along the southern slopes of the Himalayas.

The present species can be distinguished from those species of which I have material available with the following key:

In the above key Matsumuraja formosana Tak., 1925, is not considered because I have no authentic specimens. According to the description it resembles M. capz- tophoroides spec. nov. closely, but the spinal processes on the anterior abdominal tergites must be much larger, as long as or longer than the second antennal seg- ment, while spinally additional capitate hairs may occur.

Types. Holotype: apterous viviparous female (measurements no. 1), from Rubus sp., Murree (7500 ft), West Pakistan, 5.VII.1964. Paratypes: apterous viviparous females with data as for holotype, and others collected on 27.VI.1964 and 30.VI. 1964.

Periphyllus vandenboschi spec. nov.

Apterous female.

Colour in life not known, but probably light green with pitch black siphunculi. In mounted specimens body about 1.35—2.00 mm long, rather slender. Tergum completely unpigmented with antennal segment I brown, and the apex of segment V and the whole segment VI dark to blackish. Hairs on dorsum numerous and long, the long spinal hairs on abdominal segment III 6—7 times as long as basal diameter of antennal segment III, with extremely fine apices. Front straight to just concave. Antennae 3/,—7/g of length of body; hairs on segment III numerous, up to 51/,—6 times basal diameter of the segment; base of segment VI with 2 hairs, the longest of which is about 0.12 mm, 14 times diameter of proces- sus terminalis, 11/, times the length of the basal part of the segment; the shortest of the two 0.09 mm; processus terminalis about as long as antennal segment III, 3—4 times basal part of segment VI. Rostrum reaching to the hind coxae; last segment rather thick and obtuse, just shorter than second joint of hind tarsi, with 4—7 hairs besides the 3 subapical pairs. Siphunculi deep black, 2/3 of the second

joints of hind tarsi in length, cylindrical or with smallest width in the middle and there about 0.045 mm thick, only on the wide flange reticulated with one row of cells with sometimes one or two cells of a second row. Cauda pale, rather well developed, 1/,—2/; times as long as its basal width, semioval to semicircular, not constricted at base, with many hairs. Legs pale with the tarsi dusky, rather slender; first tarsal joints with 5, 5, 5 hairs.

Larvae.

First instar larvae with the siphunculi black as in adults, all with long and fine hairs, without pleural hairs on abdomen, with 2 caudal hairs, with 4 hairs on the subanal plate; hairs on last antennal segment (fourth) as in adults.

Discussion. Two large samples of this aphid, consisting only of apterae vivi- parae and larvae were collected on the petioles of an Acer sp. near Murree. The Director of the Royal Botanic Gardens, Kew, England, most kindly supplied the information that the most likely Acer spp. in the vicinity of Murree would be A. caesium Wall. ex Brand, A. villosum Wall. or A. pictum Thunb. The aphid colonies were heavily attended by ants.

Very few Periphyllus species have only 5 hairs on the first tarsal joints normally, though this may occur in small specimens of some species that normally have 7 tarsal hairs. Characteristic for the adult apterae are the complete absence of local sclerotisation or pigmentation in contrast to the quite black cylindrical siphunculi, the embryos with normal hairs, and the length and interrelation of length of the two long hairs on the basal part of antennal segment VI. In most respects the species resembles P. obscurus Mamontova from Acer campestre, but that species has conical and slightly more reticulated siphunculi, pigmentation on the head and abdominal tergite VIII, faint sclerites at the bases of the dorsal hairs, and 7, 7, 7 hairs on the first tarsal joints. A nearly related species from Iran has nor- mally 3, considerably longer, hairs on the basal part of last antennal segment, 7, 7, 7 hairs on the first tarsal joints, and aestivating larvae with foliate marginal hairs.

The species is named after Dr. R. van DEN BoscH, Berkeley, California, who discovered this and nearly all the other species described in this paper.

sp., Murree (7500 ft), West Pakistan, 4.VII.1964 (R. VAN DEN BoscH), P-VII-4a. Paratypes: many apterous viviparae with data as for holotype, and others collected on 27.VI.1964 (R. VAN DEN BoscH), P-VI-27a.

Pseudessigella gen. nov.

Body elongated, narrow, with few hairs. Eyes without distinct triommatidia. Antennae in adults of 5 segments. Last rostral segment not subdivided, very short and blunt. Siphunculi, rimmed pores on a very small, hairless sclerite. Cauda rounded. First tarsal joints with 5 ventral hairs, in apterae not with dorsal hairs, those of hind legs ventrally 11/, times as long as dorsally. Claws not with cleft apices.

Type-species: Pseudessigella brachychaeta spec. nov.

Discussion. The genus is nearly related to Ewlachnus del Guercio. It lives like that genus on the needles of Pinus spp. If differs from Ewlachnus in having 5 instead of 6 antennal segments and in that respect agrees with the American genus Essigella del Guercio which it also strongly resembles in the extremely short processus terminalis. It differs from Essigella in having claws with simple, acute apices.

Pseudessigella brachychaeta spec. nov.

Apterous viviparous female.

In life pale green. In mounted specimens body about 2.0—2.6 mm long, very elongated, about 31/, times as long as its maximum width. Tergum membranous, with extremely small fuscous sclerites around the bases of the dorsal hairs, with similarly coloured roundish pleural and marginal intersegmental sclerites (‘‘Mus- kelplatten”) of about 0.02 mm in diameter, and with pleural, longitudinal groups of 2—3 irregular sclerites pigmented like the smoky stigmal plates. Dorsal hairs on abdominal tergite III about 14 in number, 8 of which are marginal, curved, with incrassate apex, only about 0.0125—0.017 mm long. Head pale brownish yellow, dorsally and frontally with hairs like the dorsal ones, ventrally with thin acute hairs of about 0.046 mm long. Front strongly convex. Antennae short and curved, evenly pale brownish yellow with slightly darker apex, 1/.—1/4 of length of body, about 11/3 times as long as the width of the head across the eyes, without secondary rhinaria; segment I and II smooth, but the other segments very in- conspicuously imbricated; primary rhinaria of segment IV about equal to basal diameter of segment V, hardly larger than the primary rhinarium of segment V which is only 1/, of its diameter from the tip of the segment, and round in shape; hairs on segment III sparse, blunt, short, only half as long as the diameter of the segment as its narrowed base. Rostrum reaching beyond the middle coxae; apical segment very blunt, short, about 1/3 of the second joint of hind tarsi, with only the 3 subapical pairs of hairs. Siphunculi small, only 0.02 mm in diameter, hardly elevated, placed on a pale brown hairless sclerite of about 0.042—0.046 mm in diameter. Abdominal tergite VIII consisting of one wide dusky sclerotic ring, with 16—18 very short hairs. Cauda semilunar, blunt, thick, over twice as wide as

220 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 8, 1966

long, with some 30 hairs of various lengths. Legs pigmented like the head, with the fore and middle femora very strongly swollen on basal 1/, part dorsally, ventrally almost straight; hind tibiae nearly twice as long as the middle tibiae; first tarsal joints elongate, those of hind legs ventrally 11/, times as long as dorsally, 21/9 times diameter of the joint, with 3 (one short, two long) hairs ventro-apically and 2 hairs ventrally more basad; second tarsal joints only at the very apex darkened; claws slender and acute.

(1—6, from Pinus wallichiana (P. excelsa), Murree, West Pakistan, 4.VII. 1964).

Discussion. This aphid lives on the very long needles of the host plant, like members of the genera Ewlachnus and Essigella. It is easy to distinguish the species from related aphids: no other species of this group is known with simple, sharp claws and five antennal segments.

Types. Holotype: apterous viviparous female (measurements no. 1) from Pinus wallichiana (excelsa), Murree, West Pakistan, 4.VII.1964 (R. VAN DEN BOSCH), P-VII-4d. Paratypes: apterae viviparae with data as for holotype.

ABSTRACT

This part of the catalogue contains the end of the subfamily Amphipyrinae and the sub- families belonging to the group of the Quadrifinae, being the last part of the family Noctuidae.

The particulars for each species are given in the same sequence as in the preceding parts: time of appearance, discussion of the biotope(s), new localities and variation.

AMPHIPYRINAE (voortzetting)

Charanica Billberg

Charanica trigrammica Hufnagel. Tijdschr. Entom. 85 : 87; Cat. VII : (414). In het Hafdistrict en het westelijke deel van het Fluviatiele District zijn enkele nieuwe vindplaatsen bekend geworden: Sexbierum (1964, STOBBE), Aerdt (1965, PEERDEMAN), Middelie (1952, DE BOER), Purmerend (1946, in aantal, HUISEN- GA), Capelle aan den IJssel (VERKAIK), Melissant (1959, HUISMAN). Waarschijn- lijk zijn dit voor het grootste deel toch wel zwervers van de zandgronden, hetzij uit het duingebied (op Goeree komt de vlinder ook voor), hetzij dat zij behoorden tot een populatie van een nabij gelegen spoorbaan. Daarentegen schijnt de vlinder wel tot de fauna van het Amsterdamse Bos te behoren, daar hij hier vrij geregeld, doch niet in groot aantal, wordt gevangen (PEERDEMAN). Een merkwaardige vindplaats is ook Botshol (WOLSCHRIJN c.s.), hoewel dit moerasgebied meer „zandgrondsoorten” heeft opgeleverd. Overigens is aan de in 1943 gegeven ver- spreiding niets nieuws toe te voegen, ook niet wat het voorkomen op de wadden- eilanden betreft.

De vliegtijd kan al begin mei aanvangen. De vroegste datum is nu: 5.V, in 1963 waargenomen door Pater MUNSTERS te Stein, zodat de uiterste data nu worden: 5.V—27.VII.

Variabiliteit. De donkere vormen zijn over het algemeen zeldzaam en ontbreken op vele plaatsen zelfs volkomen. Van een toename is niets te bespeuren. Of ze dominant zijn, is zeer te betwijfelen. COCKAYNE vermeldt in Ent. Rec. 37 : 142 (1925) het resultaat van een kweek, afkomstig van een prachtig donker 9. Geen enkel exemplaar van de F,-generatie was donker. Zeer waarschijnlijk was de vorm dan ook recessief.

222 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (872)

gels zijn zeldzaam. Nieuwe vindplaatsen: Aerdenhout (VAN WISSELINGH); Stein (Missiehuis).

f. erubescens Turati, 1909. Exemplaren met opvallend roodachtig gekleurde voorvleugels zijn evenmin gewoon. Nieuwe vindplaatsen: Frederiksoord, Heems- kerk (Zoöl. Mus.); Stein (Missiehuis).

f. semifuscans Haworth, 1809. Exemplaren waarbij de voorvleugels vanaf de schaduwlijn duidelijk donkerder zijn dan de basale helft (plaat 3 fig. 1), werden nog aangetroffen te: Holten (LUKKIEN); Zeist (GORTER); ‘s-Graveland (WEs- TERNENG); Den Haag, Oostkapelle, Vijlen (Zoöl. Mus.) ; Stein (Missiehuis, VAN DE POL). :

f. fuscolimbata nov. De voorvleugels verdonkerd vanaf de tweede dwarslijn tot de achterrand. Plaat 3 fig. 2. Twello, 4, 2.VI.1938 (holotype), Vijlen, &, 1963 (Zoöl. Mus.); Nieuwkuik, &, 1952 (DIDDEN); Montfort, 4, 1960 (MAASSEN).

[Fore wings darkened from the postmedian to the outer margin.]

f. paradoxa nov. Grondkleur van de voorvleugels donkerbruin, maar de ruimte tussen eerste dwarslijn en schaduwlijn lichtbruin, zodat een brede lichte midden- band ontstaat. Plaat 3 fig. 3. Stein, &, 29.V.1960 (holotype, VAN DE Por). Een exemplaar van 1961 in de collectie van het Missiehuis aldaar.

[Ground colour of the fore wings dark brown, but the area between central shade and postmedian pale brown, so that a broad pale central band results.]

f. brunnea Lenz, 1927. De vorm met eenkleurig donker bruinachtige voor- vleugels met min of meer duidelijke dwarslijnen werd verder bekend van: Apel- doorn (LEFFEF); Warnsveld (CARON); Ruurlo (LUKKIEN) ; Babberich (ELFRINK) ; Slijk-Ewijk, Rijckholt, Eijs (VAN DE POL); Zeist (GORTER); Oostvoorne (LUCAS); Geulem, Eperheide, Vijlen (Zoöl. Mus.); Stein (Missiehuis); Gronsveld (VAN AARTSEN ).

f. obscura Tutt, 1891. De vorm met donkere zwartachtig grijze voorvleugels met meestal slechts twee dwarslijnen werd nog aangetroffen te: Holten (LuK- KIEN) ; Twello, Doetinchem, Gronsveld, Eperheide, Vijlen (Zoöl. Mus.); Eiber- gen (VAN WESTEN); Babberich (ELFRINK); Amersfoort (CARON); Oostvoorne (Lucas); Stein (Missiehuis).

(De donkere vormen worden dus vooral in het oosten en zuidoosten van het land gevonden en niet zelden beide op dezelfde vindplaatsen).

f. pallidalinea Tutt, 1891. Eenkleurig donkere exemplaren, waarbij de eerste en tweede dwarslijn opvallend licht afgezet zijn, werden gevangen te: Twello, Berg en Dal (Zoöl. Mus.); Hoog-Keppel (LEFFEF); Stein, Rijckholt (VAN DE Por). Blijkbaar vrij zeldzaam.

f. basivoluta Wihan, 1917. Van de vorm waarbij de halve en de eerste dwarslijn langs de voorrand van de voorvleugels met elkaar verbonden zijn door een don- kere lijn, werden de volgende nieuwe vindplaatsen bekend: Colmschate, Hoog- Keppel, Bussum, Rotterdam, Geulem (Zoöl. Mus.).

f. approximata Haworth, 1809. Exemplaren, waarbij de schaduwlijn en de eerste dwarslijn elkaar aan de binnenrand van de voorvleugels sterk naderen, zijn

(873) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 223

stellig niet zeldzaam. Nieuwe vindplaatsen: Amerongen (GORTER); Amsterdam, Heemskerk, Eperheide (Zoöl. Mus.); Wassenaar (VAN WISSELINGH); Leiden, Oostvoorne (Lucas); Rijckholt (VAN DE POL).

f. convergens Wihan, 1917. Van de vorm, waarbij schaduwlijn en eerste dwars- lijn elkaar aan de binnenrand raken, werden enkele nieuwe vindplaatsen bekend: Zeist (GORTER); Heemskerk (Zoöl. Mus.).

f. fasciata Krombach, 1920. Een exemplaar met duidelijk verbrede midden- schaduw is afgebeeld op plaat 3 fig. 4. Nieuwe vindplaatsen: Noordlaren, Heem- stede, Stein (VAN DE Por); Havelte (VAN DER MEULEN); Wilp (TER LAAG); Woudenberg, Bunnik (CARON); Zeist (GORTER); Heemskerk (AUKEMA); Oost- voorne (LUCAS); Deurne (Nies); Eperheide (Zoöl. Mus.). Blijkbaar een vrij verbreide vorm.

[KROMBACH writes: “Mit auffallend verbreiteter Mittelbinde”, with strikingly widened central band. In my opinion this means that it is the central shade which is widened, not the central area (‘‘Mittelfeld’’ in German). TURNER’s translation “with extraordinarily wide band” in Brit. Noct., suppl. 1: 322 (1934) is not exact.}

Hoplodrina Boursin

Hoplodrina alsines Brahm. Tijdschr. Entom. 85 : 96; Cat. VII : (423). Van de waddeneilanden is de soort nu bekend van Schiermonnikoog (VAN WISSE- LINGH), Terschelling (gewoon, LEFFEF, TANIS) en Vlieland (CAMPING). Overi- gens is aan de in 1943 opgegeven verbreiding van de haast overal gewone vlinder niets nieuws toe te voegen.

De uiterste data van de vliegtijd blijven bijna ongewijzigd: 3.VI—16.VIII.

Variabiliteit. f. suffusa Tutt, 1891. De vorm met sterk verdonkerde vleugels is niet zeldzaam en komt vrij verbreid onder de soort voor.

f. elegans Lempke, 1943. Exemplaren met helder geelbruine scherp getekende voorvleugels werden nog aangetroffen te: Borne (VAN WESTEN); Apeldoorn (Zoöl. Mus.) ; Heemstede (VON HERWARTH); Hendrik-Ido-Ambacht (BOGAARD).

(f. rufescens Lempke, 1943. Moet vervallen. Het exemplaar behoort zonder twijfel tot Hoplodrina blanda; de roodachtige tint is geheel verdwenen. De twee soorten zijn naar de genitalién niet met zekerheid te determineren.

Hoplodrina blanda Schiff. Tijdschrift Entom. 85 : 94; Cat. VII : (421). Al is de minder bont getekende soort over het algemeen niet zo gewoon als de vorige, uit de combinatie van beide lijsten van vindplaatsen blijkt wel, dat hij toch in vrijwel het gehele land is aan te treffen, evenmin zonder duidelijke voorkeur voor een of meer bepaalde biotopen. De vlinder is nu bekend van drie van de wadden- eilanden.

De vliegtijd kan tot begin september duren. De uiterste data zijn nu: 12.VI— 6.IX. De laatste datum werd in 1951 genoteerd door LANDSMAN.

Variabiliteit. f. suffusa Prout, 1895. Op het ogenblik is de donker bruingrijze vorm de overheersende vorm van het 2 geworden. Bij het ¢ komt hy daarentegen veel minder voor (in het Zoöl.

Hoplodrina ambigua Schiff. Tijdschr. Entom. 95 : 278; Cat. XI : (889). Het is nu wel duidelijk, dat deze soort in de loop van de veertiger jaren van onze eeuw zijn areaal in noordelijke richting heeft uitgebreid en daarbij ook ons land heeft bereikt. Daar hij elk jaar in de trekverslagen is opgenomen, is het niet moeilijk een goede indruk te krijgen van het verloop van het voorkomen hier te lande. Na de vangst van het eerste exemplaar in 1946 werd ambigua pas weer in 1949 ge- meld, nu in acht stuks. Maar reeds de drie volgende jaren vloog het aantal omhoog tot 110, 280 en 223 stuks. In 1954 en 1955 vielen de totalen terug tot resp. 98 en 64 stuks, maar beslist slecht waren 1956, 57 en ’58 met 17, nul en 16 stuks, zodat het er op begon te lijken, dat de vlinder zich hier op de duur niet zou kun- nen handhaven. Doch het jaar daarop kwamen we weer tot bijna 200 stuks. Op- vallend goed waren 1961 en 1962 met 2863 en 2388 getelde exemplaren. 1963 bracht het slechts tot 135 stuks, maar 1964 was weer veel beter (480 stuks). Zeer slecht was 1965 (38 stuks). Er zijn dus sterke schommelingen in de aantallen, die voor een belangrijk deel wel veroorzaakt worden door oecologische factoren.

Hoewel de vlinder op verscheidene plaatsen benoorden de grote rivieren is waargenomen, is toch wel duidelijk geworden, dat hij zich ten zuiden ervan het beste thuis voelt. Hier wordt hij het regelmatigst waargenomen en hier zijn de aantallen in de regel ook het grootst.

De vliegtijd kan in de tweede helft van mei beginnen en nog voortduren tot in oktober. De uiterste data zijn nu: 21.V—10.X. Ongetwijfeld komen er twee gene- raties voor, waarvan de grens in juli ligt. Alle jaren bij elkaar geven echter geen scherpe scheiding meer te zien, hoewel die er in de afzonderlijke seizoenen in de regel wel is.

Op de waddeneilanden is ambigua tot nog toe alleen op Terschelling aange- troffen (1956, LEFFEF). De in 1953 vermelde vindplaats Leeuwarden bleek later onjuist te zijn. Overigens volgt hierna een volledige lijst van alle plaatsen, waar de vlinder tot nog toe is waargenomen, zonder verdere biezonderheden, daar die in de trekverslagen te vinden zijn.

Spodoptera Guenée

Spodoptera exigua Hübner. Tijdschr. Entom. 85: 104; Cat. VII: (431). Het voorkomen in Nederland, zoals wij dat tot nog toe kennen, demonstreert weer duidelijk, dat voor verschillende soorten de laatste 20 jaar een gunstiger periode is aangebroken, die hen in staat stelt veel verder noordwaarts te komen, dan dat daarvoor het geval was, ook al houden we rekening met het intensievere vangen in de moderne tijd. Na de eerste vangst in 1868 duurde het tot 1937, vòòr de soort weer in ons land gesignaleerd werd, terwijl het volgende jaar zelfs tien stuks gevangen werden. 1941 leverde één waarneming, maar vanaf 1944 tot nu is de vlin- der in meer dan de helft van het aantal jaren hier te lande aangetroffen. In de regel echter is het aantal exemplaren klein, maar een enkele keer komt het boven de tien (1952 met 13, 1958 met 14). Alles overtreffend echter was het jaar 1962, toen hier niet minder dan 227 stuks geteld werden, die tussen 5 mei en 20 oktober voor het grootste deel in het westen van het land werden waargenomen. Deze immigratie hing duidelijk samen met de Britse. Onze overburen bereikten echter een totaal van 746 stuks, wat ook voor hen een record betekende dat vooral veroorzaakt werd door de gunstiger ligging van de Engelse zuidkust.

Exceptioneel was de vangst van een exemplaar op 3 maart 1952 (VAN WISSE- LINGH). Ook blijkens de Engelse ervaring is dat jaar de migratie zeer vroeg be- gonnen. Soms worden de aanvliegers in mei waargenomen (1958, 1962, 1964) of in juni (1946, 1962, 1964). Juli-vangsten zijn evenmin gewoon (1868, 1937, 1938, 1952, 1962, 1964), maar komen blijkens het aantal jaren dat ze plaats von- den, toch wat meer voor. Augustus echter is nu wel duidelijk de beste maand voor de soort. In verschillende jaren is de vlinder ook in september gevangen en zelfs

(877) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 227

in oktober. De kroon echter spant het jaar 1963, toen maar één enkel exemplaar werd gemeld, en wel op 9 november! In alle jaren, dat er vroege immigranten werden waargenomen (maart, mei, juni), werden ook later in het seizoen weer exemplaren gevangen. Dit is een aanwijzing, dat het dier zich hier in de zomer althans één generatie kan voortplanten. Niets wijst er echter op, dat exigua in staat zou zijn ook wel eens onze winter door te komen. Na het topjaar 1962 kwam in het volgende jaar alleen de ene november-vangst!

In het volgende overzicht zijn alle vindplaatsen na 1943 vermeld met de jaren van waarneming zonder verdere biezonderheden. Deze zijn steeds in de trekvlin- derverslagen te vinden.

Vindplaatsen. Fr.: Sexbierum (1962). Dr.: Ruinen (1962). Ov.: Holten (1952). Flevoland: Lelystad (1962). Gdl.: Ede (1948), Dieren (1962); Warnsveld (1947); Buren (1962). Utr.: Zeist (1959).

Variabiliteit. De grondkleur van de voorvleugels varieert van een lichter tot een donkerder grijs. De ronde vlek heeft soms nauwelijks een donkerder kern, meestal is deze donker bruinachtig, soms is de kern mooi roodbruin en kan de vlek vrijwel geheel vullen. Al deze verschillen gaan echter zo geleidelijk in elkaar over, dat het met het thans beschikbare materiaal vrijwel onmogelijk is bepaalde vormen te onderscheiden. De reeds beschreven vormen kon ik onder het Nederlandse materiaal niet terug vinden.

{Spodoptera littoralis Boisduval. Tijdschr. Entom. 85: 104; Cat. VII: (431), noot 1. Van deze adventief is nog altijd slechts het ene exemplaar bekend, dat in 1922 uit een te Alkmaar in geïmporterde bananen gevonden rups werd gekweekt.

VIETTE heeft aangetoond, dat Sp. litura Fabricius, 1775, en Sp. littoralis Boisduval, 1834, twee verschillende soorten zijn, practisch alleen te onderscheiden aan het genitaalapparaat. De eerste soort komt voor in zuidoost-Azië, op Java, in Australië, op Nieuw Caledonië en op de Fidsji eilanden. De tweede is bekend van grote delen van Afrika, van Spanje, het zuiden van Frankrijk en van Syrië. Zie Bull. Soc. Linn. de Lyon 32: 145—148, 1963. In Frankrijk werd littoralis voor het eerst omstreeks 1935 te Parijs aangetroffen. De soort is daarna in vele exemplaren op verschillende plaatsen in het zuiden van de Basses Alpes tot de Pyreneeën gevangen en is er mogelijk geacclimatiseerd (DuFAY, 1962, Alexanor 2 : 207).

In Proc. Trans. South London ent. nat. Hist. Soc. 1963 : 48 (1964) wordt meegedeeld, dat littoralis op chrysanten in kassen in de zuidelijke helft van Engeland is aangetroffen, waar het dier een ernstige plaag kan zijn, daar het in staat is zich het hele jaar door in de kassen voort te planten en de rups van tal van planten kan leven, o.a. van sla en tomaten.

Ook in Denemarken is de rups herhaaldelijk ingevoerd, met bloemen uit Italië, met bana- nen, met sla van de Canarische eilanden (in 1953 zelfs meer dan 40 rupsen) (HOFFMEYER, De Danske Ugler, 2de druk : 247, 1962).

Uit al deze gegevens blijkt wel, dat nieuwe rupsevondsten in Nederland beslist niet uit- gesloten zijn. Het enige tot nu toe bekende Nederlandse exemplaar behoort inderdaad tot littoralis. Het is afgebeeld op plaat 4 fig. 8.].

Caradrina Ochsenheimer

Subgenus Caradrina Ochsenheimer

Caradrina (Caradrina) morpheus Hufnagel. Tijdschr. Entom. 85 : 94; Cat. VII : (421). Met uitzondering van Texel, waar hij ongetwijfeld ook zal voor- komen, is de vlinder nu van alle waddeneilanden bekend. Op Rottum ving Dip- DEN in 1959 twee exemplaren. Overigens is aan de in 1943 opgegeven verbreiding niets toe te voegen.

Wat de vliegtijd betreft, na de publicatie van Cat. VII is gebleken, dat mor- pheus niet zelden een (partiële) tweede generatie kan voortbrengen. De vliegtijd van de eerste kan iets eerder beginnen en wordt nu: 9.V (in 1959 genoteerd, Lucas) tot 7.VIII. De tweede is waargenomen van eind augustus tot in de tweede helft van oktober (30.VIII—21.X). Hij werd vermeld in 1949, 1953, 1959, 1960 en 1961. Vooral 1959 met zijn zeer droge en zonnige zomer en herfst leverde veel gegevens op. Uit dit jaar stammen ook de beide uiterste data van deze gene- ratie. (In 1950 trof VAN WISSELINGH op 24 februari een vers exemplaar in zijn huis aan. Dit had zich daar ongetwijfeld wel ontwikkeld).

Variabiliteit. De typische vorm met niet al te donkere voorvleugels blijkt de hoofdvorm te zijn, ook bij het moderne materiaal.

f. ochracea Lenz, 1927. De vorm met licht geelbruine voorvleugels komt niet veel voor. Nieuwe vindplaatsen: Zeist (GORTER); Halfweg (VAN AARTSEN, in Zoöl. Mus.); Zaandam (WESTERNENG); Bergeijk, Epen (VAN WISSELINGH); Oisterwijk (Lucas); Eindhoven (VAN DER WOLF).

f. fuscomarginata nov. Bovenzijde voorvleugels: de ruimte tussen tweede dwarslijn en achterrand sterk verdonkerd. Ruurlo, 3, 6.VII.1961 (holotype, LUKKIEN); Ratum (PEERDEMAN); Zeist (GORTER); Hendrik-Ido-Ambacht (Bo- GAARD); Ouddorp (VROEGINDEWEIJ).

[Upper side fore wings: the area between postdiscal and outer margin strongly darkened.]

f. spalleki Kitt, 1917. Van deze vorm, waarbij ook het wortelveld verdonkerd is, zijn geen nieuwe vangsten bekend geworden.

f. obscura Tutt, 1891. De vorm met bruinzwarte of zwartachtige voorvleugels is vrij gewoon, vooral onder het moderne materiaal, maar is over het geheel ge- rekend zeker niet de hoofdvorm.

f. semiconfluens Lempke, 1943. Exemplaren, waarbij ronde vlek en niervlek smal met elkaar verbonden zijn, werden nog aangetroffen te: Vledder, Den Haag (Zoöl. Mus.) ; Bennekom (VAN DE Por); Aalten (VAN GALEN); Zeist (GORTER) ; Leiden (VAN DER WOLF); Oostvoorne, Eperheide (Lucas); Melissant (Huts- MAN); Nuenen (NEIJTS); Epen (VAN WISSELINGH).

Subgenus Paradrina Boursin

Caradrina (Paradrina) selini Boisduval. Tijdschr. Entom. 85 : 93; Cat. VII: (420). Er kan niet de minste twijfel aan bestaan, dat de soort bij ons inheems is. De vlinder is vooral in het Duindistrict en op enkele waddeneilanden aangetrof- fen, maar is ook bekend van vrij veel vindplaatsen in het oosten en zuiden van het land, waar hij toch wel in hoofdzaak beperkt is tot de zandgronden. Hier is hij overal schaars.

Het areaal in het omringende gebied is zeer verbrokkeld. In Denemarken is de vlinder bekend van de eilanden Bornholm (hier verbreid) en Anholt (niet zeld- zaam), terwijl in 1932 een exemplaar bij Skagen in het noorden van Jutland gevangen werd. Uit het aan ons land grenzende Duitse gebied ken ik alleen een vermelding van Bremen (in 1952, JACK, 1953, Bombus 1: 322). In Belgié is selini alleen bekend van de Kempen, hoofdzakelijk van Sutendael, volgens mede- deling van de heer DE LAEVER. Op de Britse eilanden is de soort nooit aange- troffen.

De vliegtijd kan in de laatste week van mei beginnen en voortduren tot in de eerste week van augustus (27.V—4.VIII). De vroegste datum werd in 1951 te Amerongen vastgesteld (BENTINCK), de laatste in 1962 (Westenschouwen, LEF- FEF). Bij uitzondering blijkt ook bij deze soort nu en dan een zeer partiéle tweede generatie te kunnen voorkomen (8 september 1961, twee exemplaren te Burgh, LEFFEF).

Vindplaatsen. Fr.: Terschelling (betrekkelijk gewoon, LEFFEF), Vlieland. Gdl.: Wageningen; Winterswijk. Utr.: Amerongen, Zeist, Soest. N.H.: Schoorl, Egmond aan Zee, Heemskerk, Heemstede. Z.H.: Meijendel, Staelduin, Rotterdam (Kralingerhout), Arkel (1963, ZWAKHALS), Ouddorp. Zl.: Burgh, Westenschouwen, Oostkapelle. N.B.: Bergen op Zoom, Schijf, Kampina, Bergeijk, Deurne, Someren. Lbg.: De Hamert, Geijsteren, Sevenum, Swalmen, Heel, Buchten, Brunssum, Meerssen.

Variabiliteit. Botspuvat beschreef de soort naar materiaal uit het Zuid- zwitserse kanton Valais (Wallis) en gaf er de volgende diagnose van: „alis anticis argenteo-cinereis, strigis obscurioribus, macula reniformis strigaque fulgurali rufo- ferrugineis: alae posticae cinereae, ad basin dilutiores”. Zijn holotype is afgebeeld door Curor (Noct. et Géom. d'Europe 1, pl. 46 fig. 15). In overeenstemming met de beschrijving heeft het exemplaar lichtgrijze voorvleugels met twee duidelijk afstekende donkere dwarslijnen. Ook de niervlek steekt goed af. Voor de golflijn staat een rij donker roodbruine pijlvlekken. Exemplaren uit de Basses Alpes (zuid- Frankrijk) uit de collectie-CARON stemmen ermee overeen (plaat 4 fig. 1—3).

De Nederlandse exemplaren behoren niet tot deze nominaatvorm. De meeste

230 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (880)

hebben donkergrijze voorvleugels, sommige zijn wat lichter van tint, maar vrijwel alle hebben een zeer onduidelijke tekening (fig. 4—6).

Onze populaties komen daarentegen goed overeen met die van Pommeren, zoals URBAHN die beschrijft (Stett. ent. Z. 100 : 594, 1939). De oudste naam hiervoor is milleri Schultz (1862, Ent. Z. Stettin 23 : 367), beschreven als een van clavipalpis verschillende soort, die bij Misdroy aan de Oostzeekust gevangen werd. Ook daar variéren de vlinders van een lichter tot een donkerder grijs en zijn ze bijna alle zeer onduidelijk getekend.

[The Dutch populations do not belong to the nominate form, described by BoIsDUVAL after a specimen from the Swiss canton Valais and figured by CULOT (l.c.). Our specimens differ by having indistinctly marked fore wings with the ground colour varying from a paler to a darker grey. Cf. plate 4, figs. 1—6.

The oldest name for this indistinctly marked subspecies is milleri Schultz, 1862, described as a species after some specimens from Misdroy near the coast of the Baltic in the former

German province of Pommern. URBAHN gives an excellent description of this subspecies (1939, I. c.), clearly showing that it perfectly corresponds with our Dutch populations. }

Caradrina (Paradrina) clavipalpis Scopoli. Tijdschr. Entom. 85: 91; Cat. VII : (418). Met uitzondering van Texel (waar de vlinder ook wel zal voorko- men) en Rottum is clavipalpis nu bekend van alle waddeneilanden. Overigens is aan de in 1943 opgegeven verbreiding niets toe te voegen.

De vliegtijd, die in Cat. VII werd gegeven (3.IV—24.XII), blijkt nog te beperkt geweest te zijn. Wij kennen nu vangsten uit alle maanden van het jaar. Op 22 januari 1946 werd een gaaf 3 binnenshuis te Steijl aangetroffen (Broeder ANTONIUS). 12 februari (jaar?) vond KNoop een exemplaar binnenshuis te Almelo. Op 26 februari 1961 ving TER LAAG een gaaf exemplaar te Bussum op licht. Op 25 maart 1953 werd door vAN GALEN een volkomen vers dier te Aalten gevangen. Op 1 april 1962 ving TER LAAG een exemplaar te Hilversum. Op 7.IV. 1948 vond GORTER een volkomen gaaf exemplaar te Zeist. Maar natuurlijk blijven wintervangsten uitzonderingen. Overigens zijn we nog niet veel wijzer dan in 1943.

Variabiliteit. f. quadripunctata Fabricius, 1775. Exemplaren, waarbij het franjeveld van de voorvleugels opvallend verdonkerd ís, zijn niet gewoon, maar komen toch vrij verbreid onder de soort voor.

f. paradoxa nov. Niet alleen het franjeveld, maar ook het wortelveld van de voorvleugels verdonkerd. Het middenveld steekt dus licht af. Stein, 4, 18.IX.1958 (holotype, Missiehuis).

[Upper side fore wings: basal area and marginal area darkened, central area contrasts as a pale band.]

Chilodes Herrich-Schäffer

Chilodes maritima Tauscher. Tijdschr. Entom. 84 : 342; Cat. VI: (390). De vlinder blijkt inderdaad verbreider te zijn dan in 1941 bekend was, hoewel hij uiteraard beperkt blijft tot min of meer vochtige terreinen, waar riet groeit. Toch valt het aantal nieuwe vindplaatsen niet mee, al kunnen bij de 10 van 1941 nu 34 nieuwe gevoegd worden, waarbij zelfs één van de waddeneilanden. Op de meeste vindplaatsen is het dier vrij schaars, wat mogelijk echter meer schijn dan werke- lijkheid is.

De vliegtijd blijkt vrij lang te zijn. De vroegste datum is nu 10 juni (1948, Meerssen, RıJK), maar de vlinder is waargenomen tot eind augustus en zelfs tot ver in september toe: 25.VIII.1959, Hendrik-Ido-Ambacht (BOGAARD), 2.IX. 1956, Groessen (VAN DE POL), 28.IX.1941, een klein exemplaar. Botshol (PIET). Mogelijk is hier een enkel exemplaar van een dan wel zelden voorkomende (par- tiéle) tweede generatie bij.

Variabiliteit. TAUSCHER beeldt zijn exemplaar van Noctua maritima af met grijze voorvleugels, waarop de donkere aderen duidelijk afsteken en zijn be- schrijving is met deze figuur in overeenstemming (,,Alae anticae cinerascentes venosae ...... ”) (1806, Mém. Moscou 1: 211, pl. XIII, fig. 5). Weinig Neder- landse exemplaren komen hiermee overeen. Wel bezitten veel exemplaren grijze

232 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (882)

voorvleugels, maar de donkere adertekening is zelden zo sterk als door TAUSCHER beschreven en afgebeeld wordt. Zijn exemplaar werd in 1805 aan de Oostzeekust in Koerland gevangen en het is mogelijk dat de soort daar sterker getekend is dan bij ons. Zo lang hierover niets bekend is, lijkt het me het beste alle exemplaren met grijze voorvleugels zonder afwijkende tekening als typisch te beschouwen. Niet zelden is deze grijze tint met iets bruin gemengd, zodat overgangen naar f. ulvae ontstaan.

f. ulvae Hübner, [1818—1819}. HÜBNER beeldt twee verschillende vormen af onder deze naam. De eerste (fig. 635, 636) die uiteraard de prioriteit heeft, is een vorm met lichtbruine voorvleugels, waarbij het achterrandsveld echter grijs is (althans bij het exemplaar van de „Sammlung” in de bibliotheek van de Ned. Ent. Ver.). Een dergelijke maritima heb ik nooit gezien. Voorlopig zou ik de naam willen gebruiken voor alle exemplaren met bruine voorvleugels, zoals SOUTH er ook één afbeeldt in de oude editie van „British Moths’. Het merkwaardige is, dat deze vorm onder het moderne Nederlandse materiaal nauwelijks meer voorkomt! Zelfs overgangs-exemplaren met bruingrijze voorvleugels zijn schaars (bijv. Lun- teren, BRANGER). In de collectie van het Zoöl. Mus. bevinden zich alleen enkele exemplaren van Zevenhuizen met zuiver bruine voorvleugels. Dat dit verkleurde dieren zouden zijn, die oorspronkelijk grijs waren, is uitgesloten.

f. bipunctata Haworth, 1812. Vrij geregeld in een enkel exemplaar onder de soort. Nieuwe vindplaatsen: Leeuwarden, Eernewoude (CAMPING); Nijetrijne (LEFFEF); Ermelo (VAN DER MEULEN); Apeldoorn, Buren, Kortenhoef (Zoöl. Mus.); Hoorn (KUCHLEIN).

f. wismariensis Schmidt, 1858. Exemplaren met de zwarte lengtestreep zijn veel zeldzamer. Ermelo (VAN DER MEULEN); Groessen (VAN DE Por); Kortenhoef (Zoöl. Mus.); Melissant (HUISMAN).

f. nigristriata Staudinger, 1871. Is naast de door TAUSCHER afgebeelde vorm nauwelijks te handhaven.

Dwerg. Rijckholt (VAN DE POL).

Athetis Hübner

Athetis gluteosa Treitschke. Alleen enkele malen in het zuiden van Limburg aangetroffen. Of de soort hier nu inheems is, of dat we met nu en dan vanuit Belgié tot in ons land doordringende exemplaren te doen hebben, is op het ogen- blik moeilijk uit te maken. Daarvoor wordt in dit gebied op te weinig plaatsen intensief verzameld. Enkele Nederlandse exemplaren zijn afgebeeld op plaat 4 fig. 9 en 10.

In Denemarken en het omringende Duitse gebied is gluteosa nergens aange- troffen. De dichtstbij bekende Duitse vindplaats is het Mombacher Wald by Mainz, waar de vlinder omstreeks 1850 werd gevangen (RÖSSLER, 1881, Fauna Wiesbaden). Overigens slechts bekend van Karlsruhe (1952). Wijlen Dr. G. WARNECKE verstrekte mij nog deze gegevens. In België is g/uteosa alleen in het bergachtige oosten gevangen. HACKRAY vermeldt Aye-Marche-en-Famenne (in het noorden van Belgisch Luxemburg) (1947, Rev. frans. Lép. 11 : 19) en voor zover ik kon nagaan, is dit de enige bekende Belgische vindplaats van deze eeuw.

(883) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 233

(DERENNE kende alleen een oude vangst van Han-sur-Lesse, zie zijn „Addenda” etc.: 77, 1928). Op de Britse eilanden is de soort nooit gevonden. Alle Nederlandse exemplaren werden in juli gevangen (11.VII—24.VII).

Vindplaatsen. Lbg.: Stein, 9, 11.VII.1963 (Missiehuis); Epen, 9 24.VII.1954, ® 18.VII.1955, drie mannetjes 18.VII.1955 (VAN WISSELINGH).

Athetis pallustris Hübner. Tijdschr. Entom. 85 : 103; Cat. VII: (430). De vlinder blijft een zeer lokale soort in ons land, wat wel duidelijk blijkt uit het feit, dat bij de zes vindplaatsen, die in 1943 bekend waren, slechts negen nieuwe ge- voegd kunnen worden. Opvallend is het voorkomen op één van de waddeneilan- den en in het Duindistrict. Het behoeven dus zeker geen uitgebreide moerassige terreinen te zijn, die de soort als biotoop nodig heeft. Wel natuurlijk plaatsen, waar de voedselplant van de rups, de moerasspiraea, groeit.

In Denemarken schijnt de vlinder minder zeldzaam geworden te zijn. In de 2de druk van De Danske Ugler (1962, p. 257) vermeldt HOFFMEYER tenminste, dat in 1944 een flink aantal exemplaren op Seeland gevangen is, terwijl vooral sinds 1950 vrij veel nieuwe vondsten bekend geworden zijn. In België is pallustris nog steeds niet aangetroffen. Mogelijk is hierdoor te verklaren, waarom de vlinder nog nooit in de zuidelijke helft van ons land gevangen is. Een interessant artikel over de biologie en het voorkomen in Engeland werd gepubliceerd door EDELSTEN, FRYER en ROBINSON (1944, Entomologist 77 : 49 etc.).

De vliegtijd kan al half mei beginnen en tot in de tweede helft van juli voort- duren. De nu bekende uiterste data zijn: 18.V—20.VII (de laatste datum in 1965 te Wijnjeterp, G. DIJKSTRA).

Agrotis Hübner

Agrotis venustula Hübner. Tijdschr. Entom. 85 : 104; Cat. VII: (431). De vlinder komt niet alleen in het oosten en zuiden voor, maar ook op zandgronden in het noorden, is op een van de waddeneilanden aangetroffen en blijkt tevens vrij verbreid in het Duindistrict te zijn. Hoewel venustula in het goede biotoop geregeld is aan te treffen, is het dier toch maar zelden werkelijk gewoon.

De vliegtijd kan iets langer duren dan in 1943 werd opgegeven. De uiterste data worden nu: 15.V—19.VII. Aanmerkelijk hier buiten valt een vangst op 4.VIII. 1962 te Westenschouwen (LEFFEF), blijkbaar een extreem laat exemplaar.

MELICLEPTRIINAE

Chloridea Duncan

Chloridea viriplaca Hufnagel, 1766 (dipsacea L., 1767). Tijdschr. Entom. 84 : 337; Cat. VI: (385). Het voornaamste biotoop van de vlinder blijkt het duin- gebied, zowel van het vasteland als van de waddeneilanden. Het tweede is het zuiden van Limburg en dan speciaal het Krijtdistrict. Buiten deze twee gebieden zijn behalve de paar reeds in 1941 vermelde vindplaatsen slechts enkele nieuwe bekend geworden.

Uit kweekresultaten is gebleken, dat er inderdaad twee generaties voorkomen. Lucas ving 15 juni te Katwijk enige vlinders en vond twee rupsen op slangekruid, die 30.VI en 2.VII verpopten. In de tweede helft van juli kwamen beide poppen uit. In 1959 vond AUKEMA te Egmond een rups op nachtsilene (Silene nutans L.). De vlinder daarvan kwam 4.VIII uit de pop. De hoofdvliegtijd valt ongetwijfeld in de maand juni. Van juli bezit ik op het ogenblik acht data, zonder duidelijk hiaat verspreid over de hele maand. Dan nog vijf in augustus en twee in mei. De reeds in 1941 vermelde aprildatum schijnt wel een grote uitzondering te zijn. Voor zover de gegevens het nu toelaten, kunnen we de twee generaties als volgt vaststellen: de eerste (bij uitzondering in april) de tweede helft van mei (20.V) tot in juli (16.VII nog?), de tweede van de tweede helft van juli tot de tweede helft van augustus (21.VII—20.VIII). Deze tweede generatie is waarschijnlijk slechts partieel.

Chloridea maritima Graslin. Tijdschr. Entom. 84 : 336; Cat. VI: (384). De vlinder is vooral verbreid in heidestreken, maar blijkt ook hier en daar in het Duindistrict voor te komen en is zelfs van één van de waddeneilanden bekend. Over het algemeen is hij niet gewoon.

De vliegtijd kan iets vroeger beginnen dan in 1941 bekend was. De uiterste data

(885) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 235

worden nu: 20.V—18.VIII. De meeste vangsten stammen uit juni en juli. De tweede generatie is hoogstwaarschijnlijk partieel.

Variabiliteit. De nominaatvorm vliegt in de Vendée. De bontere sub- species van het noordwesten van Europa, waartoe dus ook onze populaties behoren, werd door HOFFMEYER onderscheiden als subsp. septentrionalis. Deze naam is echter gepreoccupeerd. BOURSIN gaf als nieuwe naam subsp. warneckei (1963, Linn. Belg. 2: 125, noot 3; 1964, Bull. mens. Soc. Linn. Lyon 33 : 240).

Chloridea peltigera Schiff. Tijdschr. Entom. 84 : 335; Cat. VI: (383). In de loop van de jaren is de vlinder ín alle provincies behalve Utrecht aangetroffen, maar hij blijft een zeldzaamheid, die lang niet elk jaar in Nederland wordt waar- genomen. Het hoogste aantal exemplaren werd tot nog toe in 1958 geteld, name- lijk 11 stuks.

Wat de vliegtijd betreft, is peltigera in alle maanden van mei tot in de tweede helft van september gevangen. Alle exemplaren van mei, juni en zeker nog van begin juli zijn immigranten, die van de tweede helft van juli en later afstamme- lingen daarvan. Maar of de laatste zich steeds hier te lande ontwikkeld hebben, blijft de vraag. De beste maand ís augustus. Uit september zijn slechts vijf vangsten bekend en uit oktober geen enkele.

Lbg.: Bunde, 27.VIII.1964 (LEFFEF).

Variabiliteit. De vlinder is zeer variabel, zowel wat de grondkleur van de voorvleugels als wat de sterkte van de tekening betreft. In een voortreffelijk artikel heeft KETTLEWELL aangetoond, dat beide in elk geval voor een groot deel afhangen van de temperatuur van de actieve fase van de pop, dat wil zeggen van de fase gedurende welke de afgebroken weefsels van de rups omgezet worden in die van de vlinder. En daar de temperatuur weer de lengte van deze fase bein- vloedt, hangen kleur en tekening dus af van de duur van de actieve fase. Daaren-

236 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (886)

tegen heeft de temperatuur gedurende de passieve fase (dat is de fase van de afbraak, de tijd onmiddellijk na de verpopping) niet de minste invloed. Zie Proc. Trans. South London ent. nat. Hist. Soc. 1943—1944 : 69—79, pl. I, 1944. Het op plaat 4 fig. 11 afgebeelde exemplaar heeft zeer lichte voor- en achtervleugels en komt overeen met KETTLEWELL’s experiment 4. De poppen hiervan werden gedurende de actieve fase aan een hoge temperatuur blootgesteld (37° C.), zodat ze zich snel ontwikkelden. Dit zou er op kunnen wijzen, dat zulke lichte exem- plaren immigranten uit tropisch Afrika zijn. Een dergelijk licht exemplaar is ook dat van Eindhoven (1964), terwijl een groot deel van de andere hier gevangen dieren min of meer er mee overeenstemmen.

f. condolens Schawerda, 1914, Verh. zool.-bot. Ges. Wien 64 : 365. De zwarte band langs de achterrand van de achtervleugels is sterk verbreed en mist de lichte vlek bij de binnenrandshoek. Plaat 4 fig. 12. Bunde, 1964 (LEFFEF).

(Het exemplaar lijkt het meest op de nummers 4 en 5 van KETTLEWELL’s expe- riment 7, dat betrekking had op poppen, die niet konden overwinteren, maar zich onmiddellijk moesten ontwikkelen. De achtervleugels zijn echter donkerder).

f. obscura nov. Grondkleur van voor- en achtervleugels witachtig met iets créme tint, maar de voorvleugels sterk verdonkerd door de zware donker bruingrijze tekening: het gehele wortelveld is donker, een brede donkere band loopt basaal- waarts van de golflijn en de rest van de voorvleugels is min of meer donker be- stoven. De vorm lijkt het meest op KETTLEWELL’s exemplaren van experiment 5, maar de grondkleur is witter. Plaat 4 fig. 13. Hoorn, 4, 20.VIII.1958 (holotype, Zool. Mus.).

{Ground colour of the fore wings whitish with slight creamy tint, but the fore wings strongly darkened by the heavy dark brown-grey markings: the whole basal area is dark, a broad band basad of the submarginal, and the remainder of the fore wings more or less covered by dark scales. ]

Chloridea armigera Hübner. Tydschr. Entom. 84: 335; Cat. VI: (383). Terwijl van deze soort in 1941 negen vangsten in ons land bekend waren en van de vorige soort slechts drie, zijn sinds dat jaar van armigera veel minder nieuwe waarnemingen bekend geworden dan van peltigera, zoals duidelijk uit het vol- gende lijstje van nieuwe vondsten blijkt. Van 1941 tot en met 1965 is armigera slechts in vier jaren waargenomen met als hoogste totaal drie stuks in 1950. De vlinder behoort dan ook tot onze zeer zeldzame trekvlinders.

Voorjaarsimmigranten zijn tot nu toe nog nooit bij ons gezien. Alle exemplaren zijn laat in de zomer of in de herfst gevangen, namelijk tussen 9 augustus en 11 oktober. Evenmin zijn hier ooit rupsen gevonden.

Vindplaatsen. Dr.: Grollo, 18.IX.1962 (LEFFEF). Utr.: Soest, 24.VIII.1944, een vrij gaaf Q overdag honing zuigend op dophei (LEMPKE, nu in Zoöl. Mus.).

Lbg.: Swalmen, 4.X.1950 (LÜCKER); Stein, 4.X.1961 (Missiehuis); Brunssum, 7.X.1950 (DIEDEREN).

Variabiliteit. Het is niet onmogelijk, dat armigera op ongeveer dezelfde wijze op de temperatuur reageert tijdens het gevoelige stadium van de pop als peltigera. Proeven zijn met deze soort echter tot nog toe niet genomen.

(887) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 237

f. fusca Cockerell, 1889, Entomologist 22 : 4. De auteur verwijst alleen naar Entomologist 11 : 24, waar staat: „a dark brown variety”. Zo een donker exem- plaar wordt door WARREN afgebeeld in „Seitz” 3, pl. 50 rij k fig. 7. Een vrij ex- treem exemplaar van de vorm is dat van Brunssum. De voorvleugels zijn nog slechts rondom de discale vlek licht geelbruin, overigens zwartbruin, de achtervleu- gels hebben een brede donkere achterrand en ook de wortelhelft is donkerder getint.

Chloridea scutosa Schiff. Tijdschr. Entom. 84 : 334; Cat. VI : (382). Tot 1941 was slechts één Nederlands exemplaar bekend, dat in 1878 te Wolfheze gevangen was. Daarbij komen negen nieuwe waarnemingen, meer dus dan van de vorige soort. Toch is ook scutosa bij ons een zeldzaamheid. Slechts in één enkel jaar werden twee stuks gevangen, in de weinige andere jaren dat de vlinder hier gezien werd, telkens slechts één.

In Denemarken werd scutosa voor het eerst in 1942 aangetroffen, maar toen meteen al in niet minder dan een dozijn exemplaren. En in de daarop volgende jaren vermeldt HOFFMEYER in de tweede druk van zijn „Danske Ugler” (1962, p. 305) tal van vangsten. Ook Finland kende zeer goede scutosa-jaren (1953 en 1960) en in Noorwegen werd de soort in 1953 eveneens in aantal gevangen. Het lijkt er daarom op, dat de vlinder over het algemeen een meer oostelijk gele- gen trekbaan heeft, want in 1953 werd in Nederland slechts één exemplaar gevan- gen en in 1960 zelfs geen enkel. Hierop wijst ook het feit, dat in 1953 in Groot- Brittannië geen enkel exemplaar aangetroffen werd en in 1960 slechts één. Volgens een mededeling van wijlen Dr. WARNECKE was scutosa in 1942 talrijk in Noord-Duitsland en werden veel rupsen gevonden. Verschillende berichten hier- over zijn te vinden in Ent. Z. Frankfurt 56 (1942 en 1943), terwijl URBAHN in hetzelfde tijdschrift (57 : 9—14, 1943) een uitvoerig artikel over dit voorkomen publiceerde met een kaart. In 1954 werd nog een exemplaar in de omgeving van Hamburg gevangen. Overigens zijn mij geen nieuwe gegevens over het omringen- de gebied bekend.

Wat de vliegtijd betreft, zijn de vangsten hier te lande verdeeld over de maan- den juni tot en met september met een (overigens zeer laag) maximum in augus- tus.

Pyrrhia Hübner

Pyrrhia umbra Hufnagel. Tijdschr. Entom. 84 : 341; Cat. VI: (389). Uit de beide gecombineerde lijsten van vindplaatsen blijkt duidelijk, dat de vlinder over vrijwel het gehele land verbreid is zonder duidelijke voorkeur voor een bepaald biotoop. Hij is zowel op de zandgronden aangetroffen als in het Hafdistrict en het Fluviatiel District. Het menu van de rups is ook zeker niet zo beperkt als in verschillende boeken staat. Behalve de door iedere auteur vermelde Ononis (stal-

238 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (888)

kruid) werd in Cat. VI al wilg genoemd, terwijl LEFFEF de rups bij Wiessel op wilgenroosje aantrof. SEPP schrijft (7 : 37), dat VAN MEDENBACH DE Rooy hem een rups stuurde, die hij volwassen op Pelargonium had gevonden. Of het dier ook op deze plant opgegroeid was, is echter niet zeker. Te kweken is de rups heel makkelijk met varkensgras, ook uit het ei, maar het staat al weer niet vast, of hij ook in de vrije natuur op Polygonum voorkomt. In elk geval verklaart het blijkbaar vrij gevarieerde menu het voorkomen van de soort in diverse biotopen. P. #mbra is nu bekend van twee van de waddeneilanden.

De vliegtijd kan al in de tweede helft van mei beginnen (25.V.1960, Lucas; 27.V.1960, BOGAARD) en voortduren tot in de tweede helft van augustus (14. VIII. 1950, Neercanne, Leids Mus.; 17.VIII.1942, Almelo, KNoop; 19.VIII.1959, Oostvoorne, Lucas). Opvallend laat is een zeer vers exemplaar van 17.IX.1931 (VAN WISSELINGH). Dit behoort ongetwijfeld tot een wel zelden voorkomende en zeer partiële tweede generatie.

Variabiliteit. f. marginata Fabricius, 1787. Exemplaren met gele grond- kleur van de voorvleugels zijn niet zeldzaam, maar schijnen vooral bij de mannetjes voor te komen. Soms is de kleur bleekgeel en wordt de tint van de achterrands- band van de voorvleugels bleekpaars, terwijl dan ook de donkere band op de achtervleugels lichter van kleur wordt.

f. suffusa Lempke, 1941. Exemplaren met roodbruin bestoven en daardoor donkerder dan normale voorvleugels werden nog bekend van: Frederiksoord, Ruurlo, Amsterdam, Best (Zöol. Mus.) ; Wolvega, Aerdenhout, Welterberg, Epen (VAN WISSELINGH).

Panemeria Hübner

Panemeria tenebrata Scopoli. Tijdschr. Entom. 84 : 342; Cat. VI: (390). De vlinder blijkt een zeer grote verbreiding in ons land te hebben en zeker niet beperkt te zijn tot de zandgronden. Ook in het Hafdistrict en het Fluviatiel District is hij op verschillende plaatsen aangetroffen zonder dat steeds aan een verbreiding via de spoorbanen gedacht kan worden. Tevens is hij nu van een van de waddeneilanden vermeld.

Hoewel tenebrata plaatselijk heel gewoon kan zijn, is het verschillende verza- melaars opgevallen, dat het dier op plaatsen, waar het voorheen geregeld voor- kwam, later niet meer te vinden is. Zo schreef wijlen KNOOP me, dat hij de vlinder na 1950 niet meer in Twente gezien had. En BOGAARD merkte op, dat de omge- ving van Ottoland van 1958—1961 een zeer goede vliegplaats was (op 5 mei 1960 werden 25 stuks in een half uur gevangen), maar dat daarna geen enkele vlinder meer werd waargenomen. Dit kan mogelijk in verband staan met veran- deringen in de flora van het betreffende gebied. Overigens is de rups zeker niet aan één enkele Cerastzum-soort gebonden. In het Zoöl. Mus. bevindt zich een lange serie, die door DOETS gekweekt werd uit rupsen, die hij bij Kortenhoef op Ceras- tium triviale (Hoornbloem) vond, terwijl Boor in zijn tuin te Haamstede de rupsen op de gekweekte Cerastium aantrof (C. tomentosum of C. biebersteinit).

LEFFEF schreef me de volgende interessante opmerking: „De vlinders zijn moeilijk te zien. Ze vliegen razend snel in de zon, de mannetjes tot ongeveer 14 uur. De wijfjes vliegen echter door. Zodra de zon weg is, bv. door bewolking, is geen beest te zien. Ik heb de moeite genomen eens af te wachten, waar zo’n dier zich dan ging verschuilen. Dat is mij één keer gelukt. Het bleek, dat zodra een wolk voor de zon kwam, de vlinder gewoon onder de bloem kroop en daar met het kopje omlaag tegen de steel vlak onder de kelkverdikking ging zitten. Natuur- lijk volkomen onzichtbaar voor al wie boven op de bloem kijkt.”

De vliegtijd kan tot begin juli duren. De uiterste data worden nu: 27.1V— 5.VII.

Dwerg. Vaals (VAN WISSELINGH). Periphanes Hübner

Axylia Hübner

Axylia putris L. Tijdschr. Entom. 82: 236; Cat. IV: (243). Uit de hierbij afgedrukte verspreidingskaart (fig. 44) blijkt, dat de soort in allerlei biotopen is aan te treffen en moeilijk een typische bewoner van zandgronden genoemd kan worden. Ook in het Hafdistrict en het Fluviatiel District is hij thuis en kan daar op zeer vochtige plaatsen voorkomen (Naardermeer, Nieuwkoopse plassen enz.). Op verschillende plaatsen in het lage land is pufris gewoon (Tjerkwerd, Halfweg, Beemster, Hoorn, Hendrik-Ido-Ambacht). In 1963 was de vlinder op laatstge- noemde plaats zelfs zeer talrijk. Op 2.VII trof BOGAARD in zijn vangapparaat 480 stuks aan, op 5.VII niet minder dan 714! Ook bij het Rivon-onderzoek te Aerdt (1965) bleek putris gewoon te zijn, terwijl hij in 1964 bij honderden uit de Rivon-val te Roggel te voorschijn kwam (PEERDEMAN). LEFFEF vat zijn veel-

jarige ervaring aldus samen: vrijwel overal opgemerkt, maar vooral in cultuur- gebieden in zeer bescheiden aantallen, vergeleken met bijv. Amathes c-nigrum en Ochropleura plecta. Overigens sterk afwisselend in de mate van voorkomen, al naar de seizoenen. Met uitzondering van Rottum is pztris nu van alle waddeneilanden bekend. De eerste generatie kan al in de eerste decade van mei beginnen te vliegen. De grenzen ervan worden nu: 5.V (1961, Stein, Missiehuis) tot 1.VIII. Die van de (partiële) tweede worden: 5.VIII tot 14.IX. In zeer gunstige jaren komt echter zelfs een (heel kleine) derde generatie voor. Met zekerheid is deze waargenomen

in 1953, 1959, 1961, 1963 en 1964, van eind september tot half oktober (verse exemplaren!). De uiterste data ervan zijn: 26.IX—16.X.

Variabiliteit. De vlinder is variabeler dan oppervlakkig lijkt. Vooral de tint van de voorvleugels en de uitgebreidheid van de donkere kleur erop schom- melen nogal. Maar ook in de tekening komen soms interessante afwijkingen voor.

f. lignosa Hübner, [1800—1803}. Exemplaren met donkerder grondkleur van de voorvleugels, meer geelachtig oker, komen vrij verbreid onder de soort voor.

Duray, de Franse specialist van deze groep, met enkele correcties op de door hem gebruikte nomenclatuur.

JASPIDIINAE

Porphyrinia Hübner

Porphyrinia parva Hübner. Immigrant uit Zuid-Europa, die voor het eerst in een paar exemplaren in 1964 in ons land is aangetroffen. Uit Denemarken en het omringende Duitse gebied zijn mij geen vangsten bekend. In Belgié werd de vlinder op 7 juni 1958 te Wavreille bij Han-sur-Lesse aangetroffen (Lambillionea 59 : 55, 1959). In Engeland is parva herhaaldelijk vooral in de graafschappen langs de zuidkust gesignaleerd. In mei en juni 1953 was het dier er zelfs talrijk („SOUTH”, nieuwe editie 1: 348, 1961). In 1947 werden twee exemplaren in Ierland gevangen.

Van de vliegtijd hier te lande is uiteraard nog niet veel bekend. Twee exem- plaren werden in juni gevangen, het derde in augustus.

Vindplaatsen. Z.H.: Melissant, 13.VI.1964 (HUISMAN, afgebeeld in Ent. Ber. 25: 153). Lbg.: Roggel, 6.VI.1964 (PEERDEMAN); Cadier, 28.VIII.1964 (VAN AARTSEN, nu afgebeeld plaat 5 fig. 4).

Porphyrinia ostrina Hübner. Deze soort, eveneens een immigrant, is tot nu toe slechts éénmaal in ons land aangetroffen, namelijk in 1958. Ook hiervan zijn geen waarnemingen uit Denemarken en het omringende Duitse gebied gemeld, maar evenmin uit België. Wel is ostrina weer bekend van het zuiden van Engeland, maar is er toch veel minder waargenomen dan parva. Uit Ierland is slechts één vangst bekend van 1947. Zie overigens „SOUTH”, I. c.: 347.

In Ent. Ber. 19 : 135—137 (1959) heeft KUCHLEIN na zijn vangst een artikel over de soort gepubliceerd met foto van het exemplaar en kaart van de vind- plaatsen in West-Europa.

Vindplaats. N.H.: Overveen, 24.V.1958, & (KUCHLEIN). Jaspidia Hübner

Jaspidia pygarga Hufnagel. Tijdschr. Entom. 90 : 89; Cat. VIII : (499). Het voornaamste biotoop wordt in ons land ongetwijfeld gevormd door bosachtige gebieden en deze worden het meest aangetroffen op de zandgronden en in het Krijtdistrict. Toch zijn nu opvallend veel vindplaatsen in het Hafdistrict en het Fluviatiel District bekend geworden, hoewel het bijna steeds vangsten van enke- lingen betreft. Het merendeel zal dan ook wel betrekking hebben op zwervers. Zulke vindplaatsen zijn: Sexbierum (1963, STOBBE), Zwartsluis (HARSEVOORD), Weesp (Zoòl. Mus.), Amsterdamse Bos (weinig, PEERDEMAN), Nek (N.H., 1964, WIEDIJK), Hoorn (HOUTMAN), Slijk-Ewijk (5.VI en 19.VI.1961, VAN DE POL), Buren (1962, idem), Heteren (1961, HUISMAN), Geldermalsen (1962, Tuinbouw- school), Leiden (hier gewoon, Lucas), Arkel (1963, ZWAKHALS), Schelluinen (1955, SLoB), Hendrik-Ido-Ambacht (vrij gewoon, BoGAARD), Melissant (1961,

HUISMAN). Vermeldenswaard is verder Cadzand (PEERDEMAN). De vlinder is nu ook bekend van Terschelling.

De vliegtijd kan al in de eerste decade van mei beginnen. De uiterste data van de hoofdgeneratie worden nu: 9.V—14.VIII. De vroegste datum werd in 1959 door Lucas te Oostvoorne waargenomen. Het is nu wel zeker, dat in gunstige seizoenen nog een zeer kleine partiële tweede generatie kan voorkomen. Deze is bekend uit de jaren 1925, 1943, 1946, 1950, 1953, 1957 en 1963. Behalve de reeds in Cat. VIII vermelde vangsten kennen we nu de volgende: 10.1X.1943, Wassenaar (VAN WISSELINGH), 7.X.1950, Twello (COLDEWEIJ), 9.X.1953, Aer- denhout (VAN WISSELINGH), 7.1X.1957, Epen (idem), 28.IX.1957, Gassel (VAN DE Por), 22.IX.1963, Helenaveen (LEFFEF). De uiterste data ervan zijn dus: 7.1X—9.X.

Variabiliteit. f. albilinea Haworth, 1809. Deze verdonkerde vorm komt vrijwel overal onder de soort voor. Er zijn zoveel nieuwe vindplaatsen, dat het geen zin heeft ze alle op te sommen.

f. nigra nov. Voorvleugels eenkleurig zwart, de dwarslijnen en de omtrekken van de vlekken nog net zichtbaar; achtervleugels donkergrijs. Tegelen, ¢, 4.VI. 1961 (holotype, OTTENHEIJM).

[Fore wings unicolorous black, the transverse lines and the circumscriptions of the stig- mata hardly visible; hind wings dark grey. ]

f. brunnescens Lempke, 1949. Nieuwe vindplaats: Roermond (LUCKER).

f. albomarginata Spuler, 1907. Van de vorm met brede witte band op de voor- vleugels franjewaarts van de tweede dwarslijn, doorlopend van voorrand tot bin- nenrand, zijn enkele nieuwe vindplaatsen bekend geworden: Bilthoven, Vijlen (Zoöl. Mus.); Epen (VAN WISSELINGH).

f. ochrea Derenne, 1928. Exemplaren, waarbij de voorvleugels een geelachtige in plaats van een witte vlek hebben, komen wat meer voor. Nieuwe vindplaatsen: Eext (WITMOND); Abdi Sion (FLINT); Wageningen, Gassel (VAN DE POL); Babberich (ELFRINK); Aalten (VAN GALEN); Scheveningen (KALLENBACH) ; Oost- kapelle, Best, Vijlen (VAN AARTSEN, in Zoöl. Mus.); Eindhoven (NEIJTS); Heeze (VAN WISSELINGH).

Dwerg. Apeldoorn (LEFFEF).

Jaspidia deceptoria Schiff. Tijdschr. Entom. 90 : 89; Cat. VIII: (499). De vlinder is er zonder twijfel in geslaagd de laatste 15 jaar vaste voet in ons land te krijgen. Hij is al verscheidene jaren plaatselijk zeer gewoon in het zuiden van Limburg, maar werd ook aangetroffen op verschillende plaatsen in het oosten van het land.

Ook in Denemarken is deceptoria sinds 1950 minder zeldzaam geworden en is nu op enkele plaatsen zelfs gewoon (HOFFMEYER, De Danske Ugler, 2de druk : 314, 1962). Nieuwe vindplaatsen voor Sleeswijk-Holstein en de omgeving van Lübeck worden vermeld in Mitt. faun. Arb.gemeinsch. Schleswig-Holstein etc. N. F. 4: 51 (1951), 6: 57 (1953), 7: 12 en 40 (1954). Voor Belgié wordt alleen een vangst te Romont gemeld (Lambilionea 55 : 11, 1955). Na de eerste vangst in 1948 werden in het zuiden van Engeland enkele exemplaren gevangen,

(895) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 245

in 1952 en 1954 in Kent (cf. Ent. Rec. 78 : (316), 1966), 1952 (in het noord- oosten van Sussex, Ent. Rec. 64: 262) en in 1956 (in het oosten van Sussex, Ent. Gaz. 8 : 29, 1957). Hier lijkt de vlinder dus een immigrant gebleven te zijn.

De vliegtijd kan al in de laatste decade van april beginnen en voortduren tot de laatste decade van juli. De uiterste data zijn nu: 24.IV—25.VII. De vroegste vangst stamt uit 1959 (Cadier, Nies), de late uit 1962 (Montfort, MAASSEN).

Vindplaatsen. Fr.: Wijnjeterp (1965, G. Dijkstra). Dr.: Grollo (1960, LEFFEF). Ov.: Ommen (1964, VAN WISSELINGH); Abdij Sion (1964, Pater AMADEUS).

Variabiliteit. De vlinder varieert heel weinig. f. latefasciata nov. Bovenzijde voorvleugels: de witte gewaterde band duidelijk verbreed. Plaat 5 fig. 6. Simpelveld, &, VI.1954 (holotype, VAN DE POL).

[Upper side fore wings: the white submarginal band distinctly widened.}

Eustrotia Hübner

Eustrotia bankiana Fabricius, 1775 (olivana Schiff., 1775; zie voor de priori- teit van de in 1775 gepubliceerde werken supplement VII : (449)). Tijdschr. Entom. 90 : 91; Cat. VIII: (501). Er kan weinig twijfel aan bestaan, dat het oorspronkelijke Nederlandse biotoop werd gevormd door moerassige gronden, zoals dan ook in Cat. VIII werd geschreven, en nog altijd zijn zulke terreinen de aangewezen plaatsen om naar de gemakkelijk op te jagen vlinder uit te kijken. Ook op de Britse eilanden (waar hij in Engeland zelf zeer sterk achteruit gegaan is, zie ,,SOUTH”, nieuwe editie, Moths 1 : 351, 1961), is dit eigenlijk het enige biotoop, waar de vlinder is aangetroffen.

Maar in Nederland is bankiana zich de laatste decennia thuis gaan voelen in heel andere biotopen, droge zandgronden, al of niet bebost. Van tal van zulke plaatsen is het dier bekend geworden, veel te veel en veel te regelmatig, dan dat nog aan zwervers gedacht kan worden. We hebben hier een fraai voorbeeld van areaaluitbreiding door aanpassing aan diverse biotopen. Een biezonder plezierig verschijnsel, want het oorspronkelijke biotoop verdwijnt hoe langer hoe meer.

De soort is nu ook van één van de waddeneilanden bekend geworden.

De vliegtijd kan tot in de eerste decade van augustus duren. De uiterste data worden nu: 13.V—8.VIII. De laatste datum werd in 1960 door FLINT waarge- nomen in het Boetelerveld. In sommige jaren komt echter nog een zeer kleine (en dus partiéle) tweede generatie voor. Die is nu bekend uit de jaren 1957 (VAN DE POL), 1963 en 1964 (LEFFEF). De uiterste data ervan zijn: 26.VIII—22.IX. Ietwat twijfelachtig is de datum 16.VIII.1963, toen LEFFEF een exemplaar te Empe ving. Vermoedelijk is dit toch ook al een vertegenwoordiger van de tweede gene- ratie geweest.

Bovenzijde voorvleugels: aan de binnenkant van de buitenste witte dwarslijn bevindt zich op de plaats, waar deze in de regel iets naar binnen gebogen is, een volledig ontwikkelde witte donker gekernde niervlek. Plaat 5 fig. 8 en 9. Slijk-Ewijk, 4, 19.V.1960 (holotype), Winterswijk, &, 15.VI.1958, een exemplaar, dat tegelijk het kenmerk van f. obsoleta bezit (beide in collectie VAN DE POL).

f. edentata Lempke, 1949. Exemplaren zonder uitstekende tanden aan de eerste dwarslijn komen vrij regelmatig onder de soort voor.

f. signata Lempke, 1949. Exemplaren, waarbij de twee witte dwarslijnen door dunne zwarte lijnen afgezet zijn, zijn zeldzamer. Nieuwe vindplaatsen: Empe, Bergen op Zoom (Zoöl. Mus.); Kotten, Plasmolen, Lottum (VAN WISSELINGH); Noorden, Kampina, Heeze (Lucas); Nuenen (Nets); Annendaal (MAASSEN).

f. obsoleta Tutt, 1892, Brit. Noct. 4: 7. Exemplaren, waarbij de twee witte banden sterk gereduceerd zijn en nog slechts als dunne witte lijntjes aanwezig zijn.

Daar de rups volgens de literatuur niet alleen op zeggen, maar ook op ruwe grassen leeft, is het wel te verklaren, dat de vlinder in zijn voorkomen niet beperkt is tot moerassige plaatsen, al vormen die ook het

voornaamste biotoop voor de soort. Hij is nu ook op drie van de waddeneilanden aangetroffen.

De eerste generatie kan al in de eerste meidagen beginnen te vliegen en in gunstige seizoenen waarschijnlijk zelfs al in de laatste week van april. De uiterste data ervan zijn nu: 1.V—20.VII. De tweede generatie is nog tot in september waargenomen. De laatste datum ervan wordt nu: 10.IX (in 1955, Koor).

Emmelia trabealis Scopoli. Tijdschr. Entom. 90 : 92; Cat. VIII: (502). Het geregeldst komt de vlinder bij ons in het zuiden en midden van Limburg voor, al is het ook hier meestal beslist geen gewoon dier. In elk geval is het toch steeds een slechts plaatselijk voorkomende soort. Buiten deze provincie alleen enkele vangsten in Gelderland en Noord-Brabant.

Fig. 45. Histogram van Emmelia trabealis Scopoli.

De eerste generatie kan al in de eerste helft van mei beginnen te vliegen. De vroegste datum is nu: 12 mei. Toen werd in 1960 een exemplaar te Slijk-Ewijk gevangen (VAN DE Por). De laatste datum van de tweede generatie blijft 10.VIII. Uit het hierbij gegeven histogram (fig. 45) blijkt, dat de beste tijd voor de eerste generatie de eerste helft van juni is. De tweede generatie is duidelijk schaarser. Er zijn althans minder gegevens over beschikbaar. De hoofdvliegtijd hiervan schijnt de eerste helft van juli te zijn, wat dan wel op een snelle ontwikkeling van deze generatie moet wijzen. Heel laat is een exemplaar, dat TOLMAN 27.1X.1948 te Milsbeek ving (zeer partiéle derde generatie?).

Vindplaatsen. Gdl.: de Voorst (1953, LEFFEF); Slijk-Ewijk (1960, VAN DE Pot). N.B.: Sint Michielsgestel (1950, KNIPPENBERG); Eindhoven (1954, 1955, VAN DULM); Heeze (1959, BENTINCK).

Acontia Ochsenheimer

Acontia lucida Hufnagel. Tijdschr. Entom. 90 : 196; Cat. VIII : (606). Van dit fraaie dier is tot nog toe geen tweede exemplaar uit ons land bekend geworden. Ook uit het omringende gebied zijn geen nieuwe gegevens te vermelden.

Acontia luctuosa Schiff. Ook van deze soort is slechts één enkele vangst uit Nederland bekend (1963). In Denemarken werd op 15.VII.1949 het eerste exem- plaar op Bornholm gevangen (1949, Flora og Fauna 55 : 116), het tweede in 1965 op Seeland (op. cit. 72: 122, 1966). Uit het omringende Duitse gebied vermeldt PEETS het dier als zeer zeldzaam voor de omgeving van Hannover

(899) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 249

(Jahresber. Naturhist. Ges. Hannover 55—57 : 247, 1908). Uit Belgié wordt de vlinder vermeld van verschillende plaatsen in het zuiden van de provincies Namen en Luxemburg. Op de Britse eilanden is /wctwosa bekend van het zuiden van Engeland en is vooral langs de kuststrook van het zuidwestelijk deel gewoon.

Van vliegtijd is hier te lande uiteraard vrijwel niets bekend. Het exemplaar werd in de tweede helft van juli gevangen.

NYCTEOLINAE

Nycteola Hübner

Nycteola revayana Scopoli. Tijdschr. Entom. 90 : 92; Cat. VII: (502). In verband met het voorkomen van rupsen op eik is de soort in hoofdzaak beperkt tot de zandgronden, maar hier is hij dan ook goed verbreid. Toch is het geen soort, die gewoon genoemd kan worden. De aantallen, die met de menglicht- lampen gevangen worden, zijn in de regel klein. Wanneer men het materiaal in de oudere collecties bekijkt, rijst het vermoeden, dat de vlinder toen gewoner was (en veel variabeler) dan nu. Het is mogelijk, dat met het verdwijnen van de cul- tuur van eikehakhout (voor de schors) ook het voor de rups meest geschikte bio- toop is achteruit gegaan.

Naast de vindplaatsen op de zandgronden zijn er vrij veel daarbuiten bekend geworden. Voor een deel is dit te verklaren door het feit, dat de eik niet beperkt is tot deze grondsoort, maar een aantal van deze vondsten moeten betrekking hebben op zwervers, daar ze afkomstig zijn van plaatsen, waar wijd en zijd geen eik te bekennen is. De vlinder is nu bekend van één van de waddeneilanden.

Wat de vliegtijd betreft, er is nauwelijks een grens tussen de beide generaties, daar Lucas na 19.VIII nog 20.VIII (1944) en 21.VIII (1960) vermeldt, al zal er in elk jaar waarschijnlijk wel een korte onderbreking zijn. De tweede generatie kan bij gunstig weer tot in december blijven vliegen (7.XII.1956, Lucas), ter- wijl overwinterde exemplaren reeds half maart kunnen verschijnen (vroegste datum nu: 16.111, in 1950 waargenomen te Twello door COLDEWEIJ).

Rhenen (Landb. Hschool); Doorn (VAN DER WOLF); Zeist (GORTER); Weesp (Zoöl. Mus.); Epen (VAN WISSELINGH).

f. ramosana Hübner, 1793. Van de vorm, waarbij de voorvleugels boven de streep bruin zijn en eronder grijs, werden de volgende nieuwe vindplaatsen be- kend: Lage Vuursche, Bussum (Zoöl. Mus.); Belfeld (OTTENHEIJM). VAN WISSELINGH bezit een exemplaar van Wassenaar, waarbij bijna de gehele voor- vleugel bruin is, behalve langs de achterrand, die grijs is. Dit kan toch wel het beste tot ramosana gerekend worden.

f. atrata Sheldon, 1919. Van deze zeer donkere vorm, waartoe ik ook de zwartachtige zonder bruine tint (maar waarbij de diepzwarte ramosana-streep nog steeds duidelijk afsteekt) zou willen rekenen, werden nog exemplaren gevangen te Ruurlo (LUKKIEN), Aalten (VAN GALEN), Zeist (GORTER), Bussum (KUCH- LEIN), Bergeijk, Epen (VAN WISSELINGH), Sint Anthonis (PEERDEMAN).

f. dilutanoides Lempke, 1958, Ent. Ber. 18 : 163 (dilutana auct. nec Hubner). De vorm is beslist niet gewoon. Nieuwe vindplaatsen: Doorn (Zoöl. Mus.); Aerdenhout (VAN WISSELINGH).

Nycteola degenerana Hübner. Tijdschr. Entom. 90 : 95; Cat. VIII: (505). Uit ons land zijn geen nieuwe gegevens bekend geworden. De soort is hier stellig niet inheems.

(De laatste jaren zijn in de buitenlandse literatuur verschillende publicaties over het geslacht Nycteola verschenen. De uitvoerigste is de monografie van Ch. Duray, Révision des Nycteola Hübner (Sarrothripus Curtis) paléarctiques, Ann. Soc. ent. France 127 : 107—132, pl. H en III, 1958. Er blijken in de weste- lijke helft van Europa niet minder dan vijf verschillende soorten voor te komen.

(901) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 251

In het omringende gebied is behalve de twee uit Nederland bekende nog N. asia- tica Krulikovski aangetroffen (één vondst in Denemarken, verschillende in het uiterste zuiden van Belgisch Luxemburg). Deze soort heeft eveneens groene voor- vleugels, maar is kleiner dan degenerana (net als revayana) en heeft meer hoekige voorvleugels. Heel goed zijn de verschillen te zien in HOFFMEYER’s Danske Ugler, 2de druk, plaat 22, fig. 19 en 20 (1962). Behalve de vangsten van asiatica in het zuiden van Belgié maken overigens alle andere in onze omgeving, zowel van degenerana als van asiatica, de indruk, dat we met zwervers te doen hebben).

Earias Hubner

Earias clorana L. Tijdschr. Entom. 90 : 99; Cat. VIII : (509). Zeer verbreid in ons land, vooral in het lage deel. Opvallend veel nieuwe vindplaatsen in het Hafdistrict en in het Fluviatiel District, wat natuurlijk in verband staat met de levenswijze van de rups, die in de samengesponnen topscheuten van smalbladige wilgen leeft, vooral van Salix alba en Salix viminalis. Nu van drie van de wad- deneilanden bekend.

De eerste generatie kan reeds in de laatste week van april beginnen te vliegen. De vroegste datum is nu: 25.IV (1946, Stein, collectie Missiehuis), de laatste 12.VII. Het is thans zeker, dat in gunstige jaren nog een partiéle derde generatie kan voorkomen. Na 28.VIII, de laatste in 1949 bekende datum, werden exem- plaren gevangen op 1.IX.1959, 1 en 2.IX.1961, 4.IX.1957 en 1959, 10.IX.1956, 16.1X.1965 (koud en laat jaar). Mogelijk zijn dit althans gedeeltelijk nog late vertegenwoordigers van de tweede generatie geweest. Zekere derde generatie dieren waren echter: 20.IX.1956, Stein (Missiehuis), 13.1X.1959, vers exemplaar, Hendrik-Ido-Ambacht (BOGAARD), 15, 16 en 21.IX.1963, Arkel (ZWAKHALS), 2.X.1959, vers exemplaar, Heemskerk (VAN AARTSEN), 7.X.1961 en 18.X.1962, Hendrik-Ido-Ambacht (BOGAARD).

Dwerg. Bennekom (VAN DE Por).

Earias vernana Fabricius. Tot nog toe is slechts één exemplaar bekend, dat in 1954 in het noorden van het land werd gevangen. Volgens de literatuur leeft de rups uitsluitend op de witte abeel en dat is nu niet bepaald een algemeen voor- komende boom in Nederland.

In Denemarken is de vlinder lokaal, maar komt op alle grote eilanden voor en is ook bekend van Jutland. De vlinder zelf wordt niet veel aangetroffen, maar de rups komt vaak in aantal voor (zie HOFFMEYER, De Danske Ugler, 2de druk: 327—328, 1962). In het noordwesten van Duitsland is vernana bekend van Sleeswijk-Holstein (één exemplaar in 1937), van de omgeving van Hamburg (twee oude vondsten in 1895 en 1909, daarna weer op licht in 1952, 1953 en 1954), bij Bremen (een 9 in 1934), van Hannover (één exemplaar in 1951 op licht bij de stad) en verder in het bergachtige deel: Göttingen, Bückeburg. Niet bekend uit Westfalen. In de voormalige Rijnprovincie een 9 bij Düsseldorf in 1910 en een & zonder datum van Krefeld. Niet aangetroffen in België en op de Britse eilanden.

Van vliegtijd is hier uiteraard vrijwel niets bekend. In Denemarken heeft de vlinder twee generaties van mei tot in augustus.

Hylophila Hübner

Hylophila fagana Fabricius (prasinana auct.). Tijdschr. Entom. 90 : 99; Cat. VII : (509). De soort met de drie zilverkleurige dwarslijnen op de voor- vleugels. De in 1949 gegeven verbreiding is goed, al zijn heel wat nieuwe vind- plaatsen bekend geworden. Hierbij zijn ook enkele in het Hafdistrict en het Flu- viatiel District, die beslist van zwervers afkomstig moeten zijn. De vlinder is nu van twee van de waddeneilanden bekend.

De normale eerste generatie kan tot in de tweede helft van juli vliegen, zodat de uiterste data nu worden: 24.1V—24.VII (de late datum in 1962 te Stein, col- lectie Missiehuis). De zeer partiéle tweede generatie, die zeker niet alle jaren voorkomt, werd aangetroffen in 1952 (Apeldoorn, Bennekom), vooral in 1953 (Apeldoorn, Bennekom, Aerdenhout, Melissant), in 1955 en 1957 (Wiessel, Apeldoorn), van 12.VIII—1.IX. Merkwaardig is vooral het 4 (stellig een zwer- ver), dat HUISMAN 12.VIII.1953 te Melissant ving, terwijl er nog nooit een exemplaar van de eerste generatie is gezien!

Bena Billberg

Bena prasinana L. (bicolorana Fuessly, 1775). Tydschr. Entom. 90: 100; Cat. VIII : (510). De grotere soort met de twee gele dwarslijnen op de voor- vleugels. Evenals de vorige soort vooral verbreid in bosachtige gebieden, maar over het algemeen toch iets minder gewoon, althans als imago. Opmerkelijk is ook, dat vrijwel geen zwervers buiten het normale biotoop bekend zijn. Een inte- ressante opmerking schreef LEFFEF me over het dier: „Mijn ervaring is, dat van de soort meer rupsen gevonden worden dan imagines, die bovendien niet goed op licht komen. Ook lijkt het me toe, dat er iets van achteruitgang is te merken. Een feit is, dat de rupsen niet op struiken leven, maar vooral in bossen bestaande uit uitgegroeide eikespaartelgen en in niet al te zwaar gestamde eiken-berkenbossen.” De vlinder is nu bekend van één van de waddeneilanden.

Note. The specific nomenclature of the last two species is in accordance with my article on this subject in Entomologist 80 : 127—132 (1947), notwithstanding the note I published in part X of the Catalogue: (806)—(807) (1951). Mr. D. S. FLETCHER (British Museum, Nat. Hist.) wrote to me: “Your article of 1947 quite clearly selects a lectotype. The para- graph “Through the intermediary … but the moth is the type, contemporary with Syst. Naturae ed. X” is beyond dispute.

Whatever second thoughts you may have had or whatever the views of Dr. DE LATTIN may be, this settlement of the name cannot be altered without a sanction of the Commission for Zoological Nomenclature.”

The same specific nomenclature as in the present supplement is to be found in the new edition of “SOUTH”.

PANTHEINAE

Panthea Hübner

Panthea coenobita Esper. Tijdschr. Entom. 82 : 197; Cat. IV : (204). Er zijn op het ogenblik twee verspreidingsgebieden in Nederland bekend, nl. het zuiden en midden van Limburg (op zichzelf ook weer geen samenhangend gebied) en een deel van de oostelijke helft van Drente. Dank zij de inventarisaties van het RIVON blijkt de vlinder in het laatstgenoemde gebied zelfs gewoner te zijn dan in het zuiden van het land. Toch heeft hij zich hier waarschijnlijk pas kunnen vesti- gen na de aanleg van de Staatsbossen. De rups leeft op spar, den (volgens HoFF- MEYER in „De Danske Ugler”, 2de druk : 15 vooral op Weymouth-den) en lork. En juist deze laatste is in Drente in flink aantal aangeplant.

In Denemarken is de vlinder thans niet alleen van de meeste eilanden bekend, maar ook van tal van plaatsen in Jutland. In Sleeswijk-Holstein heeft coenobita zich de laatste decennién over het gehele gebied verbreid en is daar nu een ge- regelde, maar niet talrijk voorkomende verschijning op de lamp (Mitt. faun. Arb.- gemeinsch. Schleswig-Holstein, Hamburg u. Lübeck, N.F. 5 : 43, 1952). In het linker gedeelte van de voormalige Rijnprovincie werd de vlinder aangetroffen bij Elmpt (1939) en bij Hüls (in 1941).

Volgens de nu bekende gegevens duurt de vliegtijd bij ons van half mei tot in de tweede helft van juli (18.V—19.VII).

Vindplaatsen. Gr.: Glimmen (VAN DE Por). Dr.: Eext (1.VII.1963, elf exem- plaren, WITMOND); Schoonlo (in 1960 en volgende jaren, vrij gewoon, LEFFEF). Lbg.: Montfort (5.VII.1957, MAASSEN); Brunssum (7.VII.1946, GIELKENS; 25.VI.1957, CLAAS- SENS); Geulem (20.VI.1953, HARDONK, in Zoöl. Mus.); Epen (15.VII.1954, VAN DE Por, 1.VII.1966, VAN DER WOLF); Vaals (27.VI.1936, LANGOHR, eerste vangst in Nederland! JUSSEN, diverse exemplaren tussen 18.VI. en 8.VII; PIJPERS en JACOBI in 1947).

Variabiliteit. De zwarte tekening op de voorvleugels kan nu eens sterker, dan weer zwakker zijn. Enkele exemplaren zijn ter illustratie hiervan afgebeeld op plaat 5 fig. 14—16.

Colocasia Ochsenheimer

Colocasia coryli L. Tijdschr. Entom. 82 : 198; Cat. IV : (205). De vlinder blijkt ook in bosachtig terrein buiten de zandgronden voor te kunnen komen. VAN DER AA trof hem in de Kralinger Hout (Rotterdam) aan. In het Amster- damse Bos is hij tot nu toe echter nog niet opgemerkt. Van de waddeneilanden is coryli nu bekend van Terschelling (1956, LEFFEF) en van Texel (Koog, 1959, FISCHER). In beide gevallen werd slechts één exemplaar gevangen, zodat de vlin- der er blijkbaar nog niet gewoon is. Vindplaatsen buiten bosachtig terrein zijn niet bekend geworden, met uitzondering van Zwartsluis (HARSEVOORD).

De eerste generatie kan tot half mei vliegen. De uiterste data ervan zijn nu: 8.IV—12.VI. De tweede kan nog tot in september voorkomen, zodat de grenzen ervan nu worden: 6.VII—5.IX. De laatste datum werd door Lucas genoteerd in 1956.

256 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (906)

Variabiliteit. De vlinder is zeer variabel in allerlei kleine details, zowel wat de tekening als wat de kleuren betreft.

f. avellanae Huene, 1901. De vorm met eenkleurig grijze maar duidelijk gete- kende voorvleugels is niet zeldzaam en komt vrijwel overal onder de soort voor.

f. medionigra Vorbrodt, 1911. Hetzelfde geldt voor de vorm met zwartbruin middenveld van de voorvleugels.

f. melanotica Haverkampf, 1906, Ann. Soc. ent. Belg. 50 : 158. Voorvleugels eenkleurig zwart met nog zichtbare tekening; achtervleugels eveneens verdonkerd. Plaat 6 fig. 1. Zonder enige twijfel een moderne melanistische vorm. De auteur beschreef hem naar een exemplaar, dat in het begin van deze eeuw bij Elberfeld gevangen was. Bij Hamburg werden de eerste exemplaren ín 1948 aangetroffen, evenals bij Hannover (Bombus 1: 230, 231, 1953). Overigens zijn mij geen vermeldingen uit het buitenland bekend. Het eerste Nederlandse exemplaar da- teert van 1954. Daarna is de vorm verschillende malen gevangen, steeds in het oosten en vooral het zuiden van het land, maar altijd in een enkel exemplaar. Wilp, 20.VII.1959 (TER LAAG); Gassel, 2.VIII.1957 (VAN DE POL); Geijsteren, 1964 (NEIJTS), 1965 (VERHAAK); Tegelen, 1.VIII.1961 (OTTENHEIJM); Swal- men, 9.V.1954 (LÜCKER); Maalbroek, 16.VII.1959 (LANDSMAN, in Mus.

f. deleta Cockayne, 1951, Ent. Rec. 63 : 163. Op de bovenzijde van de voor- vleugels ontbreken de dwarslijnen. Zulke zeer zwak getekende en meestal opval- lend licht gekleurde exemplaren zag ik van Bennekom (VAN DE Pot), Arnhem, De Bilt, Hilversum (Zoöl. Mus.), Den Dolder (CARON), Zeist (GORTER).

de in 1949 gegeven verbreiding is weinig nieuws toe te voegen. De mate van voorkomen hangt uiteraard vooral af van de aanwezigheid van meidoorn en slee- doorn in een bepaald gebied. Het enige waddeneiland, waarvan de vlinder tot nu toe bekend is, is Terschelling. Enkele exemplaren van dit eiland bevinden zich in de kleine collectie van het Museum voor het Onderwijs te Den Haag, terwijl LEFFEF de rupsen in 1957 overal op meidoorn aantrof.

Geen correctie op de vliegtijd, die dus blijft: 30.VII—8.XI.

Variabiliteit. f. sfumata Schwingenschuss, 1918, Verh. zool.-bot. Ges. Wien 68: (150). Thorax, abdomen, voorvleugels en achtervleugels zwartbruin, de vlekken op de voorvleugels geel. Een min of meer verdonkerde vorm dus, maar dan met gele vlekken. Bij ons tot nog toe een rariteit. Halfweg, 9, 1965 (VAN AARTSEN, in Zoöl. Mus.); Oostvoorne, ¢, 1960 (Lucas).

f. medionigra van Wisselingh, 1966, Ent. Ber. 26 : 183. Thorax en abdomen zwart, halskraag donker bruinachtig grijs; voorvleugels met zwart middenveld en normaal licht gekleurde vlekken, wortelveld en gewaterde band donker bruin- achtig grijs, franjeveld zwartachtig; achtervleugels donker grijs. Plaat 6 fig. 3. Epen, 4, 1.X.1965 (holotype, VAN WISSELINGH).

f. bipartita Strand, 1903. Exemplaren met volkomen gescheiden ronde vlek en niervlek komen vrij verbreid onder de soort voor.

f. orbimaculata Strand, 1903. Exemplaren met een derde vlek tussen de eerste dwarslijn en de beide andere vlekken is veel zeldzamer. Nieuwe vindplaatsen: Hoog-Keppel (Zoöl. Mus.); Groessen (VAN DE POL); Oostvoorne (LUCAS).

f. coalita Meves, 1914. De vorm, waarbij ronde vlek en niervlek samengesmol- ten zijn, maar waarbij de twee kernen nog afzonderlijk zichtbaar blijven, is gewoon en overal onder de soort aan te treffen.

f. confluens Dammer, 1922, Ent. Z. Frankfurt 35 : 100 (confluens Bergmann, 1953, Großschm. Mitteld. 3 : 452). Ronde en niervlek samengesmolten tot één vlek, waarin niet meer twee verschillende kernen te zien zijn. Plaat 6 fig. 5. Aer- denhout, 1948 (tegelijk f. protensa, VAN WISSELINGH).

PLUSIINAE

Syngrapha Hübner

Syngrapha interrogationis L. Tijdschr. Entom. 90: 110; Cat. VIII: (520). Na de vangst van het eerste exemplaar in 1919 heeft het 35 jaar geduurd vòòr de vlinder weer in Nederland werd aangetroffen, maar sinds dat ogenblik (in 1955) werden we met verschillende vangsten van deze rariteit verrast. Dit meer buiten zijn normale areaal optreden is niet tot ons land beperkt gebleven. Ook in het omringende gebied zijn daarvan voorbeelden bekend geworden. HOFFMEYER vermeldt 1955 en 1959 als biezonder goede jaren voor Denemarken (De Danske Ugler, 2de druk : 352, 1962). In hetzelfde jaar 1959 werd een exemplaar bij Hamburg gevangen (Bombus 2, supplement Heft 1 : 10, 1959). In het zuiden van Engeland (volkomen buiten het normale Britse biotoop dus) werd in 1955 een vlinder te Westcliff-on-Sea (Essex) gevangen, in 1959 weer één op dezelfde plaats en in 1964 een derde in Oost-Norfolk. Combineert men deze gegevens met die uit ons land (1959 het topjaar), dan blijkt er een duidelijke samenhang tussen te bestaan. Blijkbaar bestaat in een goed jaar voor de soort in noordelijker gebieden de kans bij ons, dat de vlinder ook hier is aan te treffen.

Alle vangsten stammen uit juli en augustus.

Trichoplusia McDunnough

Trichoplusia ni Hübner. Tijdschr. Entom. 90 : 119; Cat. VIII: (529). Deze vlinder blijft wel een van de zeldzaamste immigranten voor onze fauna. Na de eerste vangst in 1931 is slechts één exemplaar binnen onze grenzen aangetroffen, namelijk in 1958, toen het een zeer goed vliegjaar voor de soort in het zuiden van Europa was. Ook uit het omringende gebied is weinig nieuws bekend geworden. Alleen in de nieuwe editie van ,,SOUTH” worden een aantal Britse vangsten na 1931 opgesomd, waarbij 1952 en 1953 zelfs als goede jaren genoemd worden. De laatste melding daar is die van twee stuks in 1962 (in Surrey en Sussex).

mogelijk nog langere toegevoegd worden, waaruit blijkt, dat de vlinder in ons land sterk verbreid is. Vooral het Hafdistrict is een ideaal gebied voor de soort, maar ook in het Fluviatiel District en trouwens ook op de hogere gronden, mits deze maar niet te droog zijn, kennen we tal van vindplaatsen. Op vochtige terreinen is de vlinder gewoon, maar hij is toch nooit zo talrijk als de volgende soort kan zijn. Van de waddeneilanden is behalve Terschelling en Texel nu ook Vlieland als vindplaats bekend geworden.

Fig. 46. Histogram van Autographa festucae L. (Cf. fig. 48)

De vliegtijd kan al in de eerste helft van mei beginnen. De vroegst bekende datum is nu 4.V. Uit het hierbij afgebeelde histogram (fig. 46) is te zien, dat festucae in deze maand echter schaars is. Juni is de goede maand voor de eerste generatie. Reeds begin juli neemt het aantal sterk af om geleidelijk over te gaan in de tweede generatie. Over alle jaren samen gerekend is er geen onderbreking in de vliegtijd, maar per seizoen is er in de regel wel een klein hiaat. De tweede generatie is talrijker dan de eerste en bereikt tegen het eind van augustus zijn maximum om in september ook weer snel in aantal af te nemen. In oktober vliegen dan soms nog enkele late exemplaren (laatste datum 17.X). Dit kunnen nakomers

260 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (910)

van de tweede generatie zijn, maar het is niet uitgesloten, dat er een snel ontwik- keld exemplaar bij is, dat dan tot een (zeer partiéle) derde generatie zou behoren. DE Roo van WESTMAAS schrijft in „Sepp”, 2de serie 1: 53 (+ 1858), dat SNELLEN in september 1857 rupsen vond op mannagras (Glyceria fluitans R. Br.), waarvan de vlinders 1 oktober uitkwamen. Deze rupsen kunnen heel goed afkom- stig geweest zijn van vroege vlinders van de tweede generatie, zodat de vlinders dan derde generatie-dieren waren.

nog slechts gedeeltelijk bekend is, is het toch reeds duidelijk, dat het ideale biotoop voor de vlinder gevormd wordt door niet te kleine moerassige terreinen. Vooral de vangsten met de RIVON-vallen door LEFFEF en G. DIJKSTRA in zulke vroeger nooit goed doorzochte gebieden hebben hiervoor belangrijke gegevens geleverd. Op de goede vliegplaatsen blijkt het dier in de regel zijn verwant A. festucae in aantal duidelijk te overtreffen.

Uit de hierbij gegeven verspreidingskaart (fig. 47) is reeds goed te zien, dat de vlinder niet tot een klein deel van ons land beperkt is, zodat we in de toekomst ongetwijfeld nog meldingen van nieuwe vindplaatsen kunnen verwachten. Op- vallend is het aantal vondsten in het noorden van Drente. Maar ook in Friesland zal de soort wel veel verbreider zijn dan we nu weten. Hetzelfde zal waarschijnlijk het geval zijn in het Hollands-Utrechtse deel van het Hafdistrict.

Over het voorkomen van de soort in Denemarken verscheen intussen een artikel van F. NAABYE, Plusia tvillinger P. festucae Linn. og P. gracilis Lmk., in log Ole Haunar 12): 19 85, 119.1 47.1960):

(913) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 263

Vergelijkt men het hierbij gegeven histogram (fig. 48) met dat van A. festucae (fig. 46), dan blijkt een duidelijk verschil tussen het voorkomen van de beide generaties te bestaan. Terwijl bij festucae de top in de tweede generatie valt, is bij gracilis de eerste generatie het talrijkst. Bovendien is deze generatie veel talrijker dan die van festucae en vliegt veel langer. Hierbij moet men wel bedenken, dat we voor gracilis slechts over de gegevens van een paar seizoenen beschikken. Zouden de waarnemingen over een reeks van jaren voortgezet worden, dan zouden de verschillen ongetwijfeld nog groter zijn.

De eerste generatie vliegt van de tweede helft van mei tot de tweede helft van augustus (21.V—23.VIII). Vangsten van mei en de eerste decade van juni zijn echter uitzonderingen. Pas in de tweede helft van juni begint de vlinder goed te vliegen om in juli zijn hoogtepunt te bereiken. In de tweede helft van augustus vliegen nog slechts volkomen afgevlogen dieren.

De veel schaarsere tweede generatie vliegt van half september tot begin oktober (17.IX—6.X). Of hij elk jaar voorkomt, is niet zeker. In het ongunstige seizoen 1965 werd er in elk geval geen enkel exemplaar van gevangen.

Variabiliteit. De grondkleur van de voorvleugels varieert nogal in tint. Soms zijn de vleugels prachtig rood van kleur, dan weer is het rood sterk geredu- ceerd en overheerst een meer gele tint. Deze uitersten zijn echter door allerlei nuances zo met elkaar verbonden, dat het onmogelijk is er duidelijk omgrensde kleurgroepen in te onderscheiden. De enige goed omschrijfbare vorm is weer een donkere, die vrijwel geheel overeenstemt met de donkere vorm van festwcae.

Autographa (Chrysaspidia) bractea Schiff. Deze fraaie immigrant (afgebeeld op plaat 6 fig. 11) werd voor het eerst in 1954 in het zuiden van ons land waargenomen. Daarna zijn nog een viertal vangsten bekend geworden. In Dene- marken werd de vlinder voor het eerst in 1962 aangetroffen (zeven stuks op Bornholm, zie KAABER & NORGAARD, 1963, Flora og Fauna 69 : 109). In het noordwesten van Duitsland werd in 1952 een exemplaar bij Harburg gevangen (Bombus 1 : 314, 1952). In België werd de eerste bractea in 1940 te Loén ver- zameld, gevolgd door vangsten te Losheimergraben (in het oosten van Luik) in 1959, te Uccle (Brussel) in 1962 en in 1963 te Buzenol (in het zuiden van de provincie Luxemburg). Op de Britse eilanden is de vlinder inheems. Hij is sterk verbreid en gewoon in Ierland, verbreid in Schotland en het noorden van Enge- land, maar ook aangetroffen in het zuiden van Wales en ten noorden van Bristol. Bovendien in 1956 in de omgeving van Londen (zwerver of trekker).

(In Frankrijk komt de vlinder voor in het hoge oostelijke gedeelte, van de Basses-Alpes tot in de Vogezen — zie LHOMME, Cat. Lép. de France et de Bel- gique : 319 —, zodat het met het oog op de Nederlandse en Belgische vindplaat- sen toch wel het meest voor de hand liggend is, dat onze immigranten vanuit zuidelijke richting naar ons land komen. Toch zit in de Britse populaties ook wel enige beweging blijkens de vangst van een exemplaar in de naaste omgeving van Londen, zodat we een overvliegen vanuit het noorden van Engeland of Schotland niet geheel kunnen uitsluiten.)

Daarnaast min of meer lokaal op de zandgronden van het binnenland en in het Krijtdistrict. Opvallend zijn vooral de vindplaatsen in het westelijk deel van het Fluviatiel District en in het Hafdistrict. In het Wadden- district nu van één van de eilanden bekend.

Autographa (Autographa) gamma L. Tydschr. Entom. 90 : 116; Cat. VIII: (526). Aan de verbreiding is slechts toe te voegen, dat de vlinder nu ook van Vlieland bekend is, zodat alleen Rottum nog in de rij der waddeneilanden ont- breekt.

In de regel komen de eerste immigranten in de loop van april. Toch zijn een enkele maal reeds in maart gamma-uilen waargenomen (1961, 1964, 1965). Dit waren dieren, die buiten in de vrije natuur werden aangetroffen als de eerste voorlopers van hun later opdagende soortgenoten. In dít opzicht van minder belang is een vlinder, die 24 maart 1960 in een kas te Aalsmeer werd gevangen, al is het een aanwijzing, welke mogelijkheid er ook soms voor het dier is om zich in ons klimaat te ontwikkelen. Hoe het verder met de soort in de loop van het jaar zal gaan, hangt in sterke mate van het seizoen af. In de regel is het wel zo, dat de grote top in het begin van de herfst valt (september, begin oktober). In sommige jaren zijn duidelijk twee toppen te onderscheiden, ook een in de loop van juli en augustus. Meestal gaat het aantal exemplaren in de eerste helft van oktober (maar niet zelden ook al vroeger) in zeer korte tijd heel snel achteruit, wat vermoedelijk toegeschreven moet worden aan een terugtrek naar het zuiden, die dan vrij plotseling plaats vindt. Achterblijvers kunnen evenwel nog tot ver in november aangetroffen worden. Zelfs in december blijken bij gunstig weer spora- disch nog dieren actief te zijn, zoals in 1948. Te beginnen met 1952 zijn ze elk jaar waargenomen met uitzondering van 1958, 1963 en 1965. Hierop sluiten dan een paar meldingen van januari-exemplaren aan (15 en 22.1.1957, Den Haag; 10.1.1960, Castricum). Waarnemingen uit februari zijn echter nog niet bekend. Dit wijst er op, dat de kans voor een imago om hier de winter door te komen, in elk geval uitermate klein is.

Wel gelukt dit een enkele maal aan rupsen, niet alleen in het gunstige micro- klimaat van kassen (hoewel hier natuurlijk veel gespoten wordt) en bakken, maar ook buiten in de vrije natuur, waar sommige ervan in staat blijken te zijn behoor- lijk lage temperaturen (10 of meer graden vorst) te doorstaan (1950, 1952, 1964,

(917) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 267

1965). Verse vlinders, die hier in mei of juni vliegen, kunnen van zulke rupsen afstammen, maar het is even goed mogelijk, dat het pas ontwikkelde exemplaren uit het subtropische Middellandse Zee-gebied zijn.

Variabiliteit. De grondkleur van de voorvleugels varieert sterk. Soms is de achterrand zeer licht en is de grondkleur zelf van een koude donkere, soms zelfs zwartachtig grijze tint (een mooie kleurvorm overigens), dan weer is de grondkleur meer met bruin of roodachtig gemengd.

f. pallida Tutt, 1892. Alle lichtere delen van de voorvleugels (wortel, voor- rand, achterrand) lichtgrijs. Plaat 7 fig. 2. Onder al onze generaties voorkomend en waarschijnlijk niet al te zeldzaam (in Zoöl. Mus. exemplaren van Westervelde, Wiessel, Apeldoorn, Nijmegen, Den Haag en Boxtel).

[From TuTtT’s text (Brit. Noct. 4: 32, 1892) one gets the impression that he had not actually seen specimens answering to the description, but that he only gave a name to GUENÉE's “Var. A”, the description of which (literally translated by TUTT) is rather mis- leading. For the French author refers to Esper, Schmetterl. in Abb. 4, 1, pl. 111 fig. 2 (cf. Noctuélites 2: 349, 1852). ESPER’s figure 1 is a specimen with very dark fore wings, whereas fig. 2, which he calls “Eine Abänderung des Weibchens” has the head, thorax and all the pale parts of the fore wings (basal, costal and outer areas) of a pale grey colour (in the specimen figured with a slightly rosy tint, but this must be extremely rare). The form occurs in all Dutch generations and is not rare. A good specimen is figured on plate 7 fig. 2, with a typical specimen for comparison. }

f. alba Cockayne, 1951, Ent. Rec. 63 : 164 (effusa van Wisselingh, 1959, Ent. Ber. 19 : 197). Grondkleur van de voorvleugels witachtig, de tekening licht grijs- achtig. Plaat 7 fig. 3. Epen, ¢, 2.IX.1958 (VAN WISSELINGH).

(Van deze uiterst zeldzame vorm kende COCKAYNE één exemplaar uit Engeland. Bovendien verwijst hij naar CuLoT, Noct. et Géom., plaat 71 fig. 17. Het daar afgebeelde exemplaar uit Silezié komt volkomen met het Nederlandse overeen).

f. rufescens Tutt, 1892. De diagnose, die in Cat. VIII gegeven werd, is niet juist. De naam moet gebruikt worden voor exemplaren met opvallend roodachtige voorvleugels. Deze vorm is niet gewoon. In Zoöl. Mus. exemplaren van Putten, Halfweg en Valkenburg.

(919) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 269

in 1949 aangetroffen en te beginnen met dat jaar werd hij een vrij geregelde, hoewel over het algemeen zeldzame, verschijning. Alleen in de jaren 1957, 1958 en 1962 werden geen meldingen over het voorkomen in Nederland ontvangen. Een echte migrant is confusa niet. Hij behoort tot de soorten, die de laatste decen- nién hun areaal uitgebreid hebben. Of het hem echter duurzaam zal gelukken hier vaste voet te krijgen, moeten we afwachten. Er zijn verschillende tekenen, dat confusa zich hier maar met moeite kan handhaven: de zeer kleine eerste generatie, die in vele jaren, dat de zomergeneratie wel aanwezig is. zelfs niet eens wordt waargenomen, de meestal zeer kleine jaartotalen, de hiaten in de jaren van voor- komen of in elk geval van waargenomen worden. Ook in de ons omringende gebieden is de vlinder nergens een gewone soort geworden, integendeel, Neder- land slaat tot nog toe het beste figuur (wat voor een deel ook kan liggen aan het aantal en het enthousiasme van de waarnemers).

Wat de Nederlandse vindplaatsen betreft, op Groningen en Drente na is de vlinder in alle provincies aangetroffen. Maar de meeste vondsten stammen uit Limburg. Nieuwe gegevens uit de omringende gebieden zijn de volgende. In Denemarken werd in 1949 een exemplaar te Randers gevangen en in 1950 een tweede te Aabenraa (beide in Jutland). In de omgeving van Hamburg werd confusa byna alle jaren van 1948 tot 1954 waargenomen, by Hannover in 1948, in de voormalige Rijnprovincie in 1953 en 1954 bij Rheidt (KUNNERT, Ent. Z. Frankfurt 67 : 152, 1957). Uit België zijn alleen vangsten gemeld van Grand- menil en Argenteau (beide in de provincie Luxemburg) (Lambillionea 57 : 47, 1957; 63 : 22, 1964). Maar onze Limburgse ervaringen wijzen er duidelijk op, dat de vlinder bij onze zuidelijke buren althans in het oosten van hun land meer te vinden moet zijn. In Groot-Brittannië is confusa een paar maal in het zuiden van Engeland waargenomen: in 1951 in Essex, in 1955 in Norfolk, Kent en Surrey en in 1962 in Devon. Vaste voet heeft de soort hier blijkbaar niet gekregen.

De gunstigste periode was bij ons het tijdvak 1950—1955 (maximum in 1955 met 31 stuks), waarmee de ervaringen om ons heen over het algemeen dus vrij goed overeenstemmen.

De vlinder is bij ons waargenomen tussen 14 mei (1954, Eindhoven, VAN DuLm) en 30 oktober (1951, Swalmen). In het histogram (fig. 49) zijn de gegevens verwerkt van alle 176 Nederlandse exemplaren, waarvan de juiste datum bekend is. Vangsten in de tweede helft van mei en de eerste helft van juni komen sporadisch voor. Tussen 10.VI en 4.VII is slechts één enkele waarneming bekend. Pas de tweede helft van juli is wat beter voor de soort. Deze gunstige periode kan voortduren tot omstreeks 20.VIII. Een tweede periode valt in de tweede helft van september en houdt nog aan in oktober. Het lijkt er dus op, dat er in een gunstig

270 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (920)

seizoen drie generaties kunnen voorkomen, de eerste tussen half mei en half juli, de tweede van half juli tot begin september en de derde van half september tot eind oktober en mogelijk zelfs begin november (nog vijf stuks op 30.X!). EIk seizoen is echter weer anders en onze gegevens zijn nog te klein om een definitief oordeel mogelijk te maken. Bovendien weten we nog niets van de biologie van de soort in ons klimaat.

De vlinder kan plaatselijk zeer algemeen zijn, zowel in vochtiger biotopen als in het droge duingebied, zoals de laatste jaren duidelijk gebleken is bij de inventarisaties door het RIVON: lange series uit Nijetrijne en de Peel, maar even goed uit Overveen en van de Schouwense duinen. In het Waddendistrict is de soort nu bekend van Terschelling (hier vrij gewoon volgens TANIS), Vlieland en Texel.

De vliegtijd kan van de eerste week van mei tot de derde week van oktober duren. De vroegste datum is nu 6.V, de laatste 21.X (in 1956 te Heerlen, CLAAS- SENS). Daar ik door het onderzoek naar het voorkomen van de vermeende Plusia tutti Kostrowicki (zie Ent. Ber. 25 : 73—79, 1965, en 26 : 25—26, 1966) over gegevens van honderden exemplaren kon beschikken, heb ik hiervan een histo- gram samengesteld (zie fig. 50). Hieruit blijkt, dat de vlinder in de loop van mei geleidelijk aan gewoner begint te worden en dat de eerste generatie het talrijkst is in de tweede helft van juni en de eerste twee weken van juli. Daarna neemt het aantal duidelijk af, maar reeds in de tweede decade van augustus neemt de vlinder weer in aantal toe om in de laatste week van augustus het maximum van de tweede generatie te bereiken. Na de eerste week van september wordt het dier veel schaarser en in de laatste week van september en in oktober worden nog slechts

sporadisch exemplaren gevangen. Een scherpe grens tussen eerste en tweede gene- ratie is er niet, al kan dit in een bepaald jaar natuurlijk wel het geval zijn. Zo nam Pater AMADEUS ALMA tussen 29.VII en 15.VIII.1965 geen enkel exemplaar waar in de val van de Plantenziektenkundige Dienst, die opgesteld stond bij de Abdij Sion (Overijsel) en die zonder onderbreking elke nacht in werking was.

De eerste generatie is wat talrijker dan de tweede. Of er nog een (zeer partiële) derde generatie kan voorkomen, is lang niet zeker. De late exemplaren zijn in de regel sterk afgevlogen. Bovendien merkte VAN AARTSEN, die de vlinder twee maal uit het ei opgekweekt heeft, dat de rupsen van hetzelfde legsel zich zeer onregel- matig ontwikkelen. Naast snel doorgroeiende exemplaren komen ook veel lang-

272 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (922)

zamer groeiende voor en het is best mogelijk, dat late vlinders van zulke trage groeiers afstammen. Van eieren afkomstig van een wijfje van de tweede generatie verscheen een vlinder op 4 november 1964. Dit derde generatie-exemplaar kwam dus uit op een moment, dat buiten geen enkele chrysitis meer vliegt. En het was afkomstig van een rups, die met nog enkele andere snel doorgegroeid was, terwijl de rest van het broedsel wilde overwinteren.

Interessant is ook het (helaas zeer magere) resultaat van een eikweek van Knoop. Van een op 3 juli 1940 gevangen ‘9 verschenen drie nakomelingen nog hetzelfde jaar tussen 3 en 20 september en drie andere pas tussen 4 en 20 juni 1941. De tweede generatie kan dus partieel zijn (in welke mate dat het geval is, weten we natuurlijk nog niet) en dit verklaart, waarom het totaal aantal exem- plaren ervan kleiner is dan dat van de eerste generatie.

door hun meerdere grootte van de later vliegende dieren. Dit is fraai te zien op

plaat 1 in Ent. Ber. 25 (1965). Er zijn echter nogal wat uitzonderingen, dieren van de eerste generatie, die opvallend klein zijn (fig. 5 van de plaat) en exem- plaren van de tweede generatie, die voor de eerste niet onder doen in grootte. Bovendien zijn er ook overgangen tussen beide grootteklassen (fig. 17 en 19). De verklaring van dit verschijnsel ligt nog in het duister.

Een ander (eveneens gradueel) verschil tussen beide generaties betreft de teke- ning op de voorvleugels. De twee metaalkleurige banden kunnen al of niet met elkaar verbonden zijn. Vergelijkt men nu grote aantallen met elkaar, dan blijken er duidelijke procentuele verschillen tussen de twee generaties te bestaan. Terwijl in de eerste generatie beide groepen ongeveer even talrijk voorkomen, zijn in de tweede generatie exemplaren met verbonden banden duidelijk in de meerderheid (zie de tabel).

banden niet verbonden banden verbonden

(bands not connected) (bands connected) generatie I 731 (49,74%) 781 (50,26%) generatie II 248 (33,11%) 497 (66,89%)

[N ote. The table clearly shows, that the markings on the fore wings of Plusia chrysitis differ in both generations. In the first generation the two coppery bands are separated nearly as often as connected. In the second generation the bands are connected much more often than separated. The most probable explanation seems to be that this character depends on a combination of hereditary and environmental factors.]

Zoals bekend variéren de banden ook sterk in kleur, van zuiver goudgeel (zeld- zaam) via kopergeel (een minder diepe tint), groenachtig geel en groenachtig naar blauwgroen. Een interessante discussie hierover is te vinden in The Entomolo- gist 28 (1895). Op p. 159 schrijft THORNHILL, dat van een lange gevangen serie een kwart groenbrons was en de rest goudbrons. Het volgende jaar ving hij eerst een serie zeer verse dieren en kweekte er ook een paar. Al deze dieren waren goud- brons. Later in het seizoen, toen de vlinders meer afgevlogen waren, ving hij er weer en deze waren alle groenbrons. Zijn conclusie is daarom, dat de groene tint een verkleuring is van de gouden. Deze mening wordt gedeeld door Kaye (1. c.: 181). Ook zijn gekweekte exemplaren waren alle goudkleurig, terwijl afgevlogen

(923) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 273

dieren een groenachtige tint hadden. Op p. 204 deelt BUNN mee, dat van een serie gevangen zeer gave exemplaren ongeveer de helft goudkleurig was en de andere helft een groenachtige tint had. Tenslotte schrijft THORNHILL (p. 229), dat hij van mening is, dat de goudbronzen tint die van de pas uitgekomen vlin- ders is, doch dat deze door invloed van het licht in groenbrons verandert. Jammer genoeg is later geen enkele lepidopteroloog meer op dit onderwerp terug gekomen. (De Engelse auteurs bedoelen met goudbrons of goudkleurig ongetwijfeld de gewone kopergele kleur, de echte goudkleur is veel zeldzamer.)

Na het zien van honderden exemplaren in allerlei stadia van ouderdom geloof ik, dat THORNHILL het bij het rechte eind had. Alle gekweekte vlinders die ik gezien heb (maar dat zijn er helaas betrekkelijk weinig), hadden prachtige koper- kleurige banden zonder groene tint. En ook SEPP beeldt zijn (gekweekte) exem- plaren zo af (Ned. Ins. 1, vijfde stuk, Tab. I, fig. 11 en 12). Hij schrijft (I. c.: 7), dat de tint overeenkomt „met den Glans van blank geschuurd geel Koper”.

Bij de lange serie gevangen exemplaren in de collectie van het Zoöl. Mus. komen zowel exemplaren zonder als met de groene tint in het geel voor. Er ís geen scherpe scheiding tussen deze twee groepen. Naarmate de dieren langer gevlogen hadden, is de groene tint intensiever. Tenslotte verandert de kleur in blauwgroen of zelfs blauwachtig. Heel verse dieren met laatstgenoemde kleuren heb ik nooit gezien en ze bestaan waarschijnlijk ook niet. De kleurvorm scintillans is dan ook geen echte vorm, maar een ouderdomsverschijnsel. Hetzelfde geldt waarschijnlijk voor de virescens-groep. Er blijken echter ook exemplaren te zijn, die nooit een groene tint krijgen, maar waarvan de banden steeds geel blijven. Wel wordt de tint steeds doffer en is tenslotte nauwelijks meer zichtbaar, maar er komt geen kleurverandering. Zo lang we door kweken niet meer van de tintverschillen van verse dieren afweten, lijkt het me het beste de groene en blauwe dieren niet meer afzonderlijk te vermelden.

Wel vermeldenswaard daarentegen zijn naar mijn mening de exemplaren met zuiver goudkleurige banden. Deze zijn van een prachtige diep donkergele kleur, die onmogelijk door verkleuring uit de koperkleurige tint ontstaan kan zijn. Deze tint is beslist zeldzaam. De enige exemplaren, die ik zelf gezien heb, zijn de vol- gende:

f. disiuncta Schultz, 1900. Met niet verbonden banden. Warga, Soest (Zoöl. Mus.); Slijk-Ewijk (VAN DE Por).

f. aurea Huene, 1901. De banden verbonden. Ruurlo (LUKKIEN); Groessen, Buren (VAN DE Por); Den Haag (Leids Mus.); Rotterdam (Zoöl. Mus.).

Aanvullingen op de afwijkingen in de tekening van de voorvleugels:

f. juncta Tutt, 1892. Zeer gewoon. Zie de tabel.

f. decorata Dannehl, 1933. Exemplaren met opvallend brede verbinding tussen de twee metaalkleurige banden op de voorvleugels komen in klein aantal vrij ver- breid onder de soort voor, zodat geen vindplaatsen meer vermeld worden.

f. croesus Bryk, 1923. Exemplaren met goudkleurige niervlek komen weinig voor. Roggel (PEERDEMAN).

Dwergen. Zeer kleine exemplaren, zelfs vergeleken met die van de tweede generatie, zag ik van Apeldoorn (Zoöl. Mus.); Aerdt, Groet (PEERDEMAN).

274 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (924)

Note. Reference is made to the observation of THORNHILL and others in Entomologist 28: 159 etc. (1895) about the colour of the bands of the fore wings. THORNHILL is of opinion that all bred or very fresh specimens have coppery bands without green tint, and that this tint is only a question of fading.

Having examined hundreds of specimens in all stages from very fresh to utterly worn I am inclined to agree with TORNHILL. The older the specimens are the greener they become, till at last they are blue-green or even quite bluish. Yet there are specimens the bands of which always remain yellowish. The colour becomes duller and duller, till at last it is hardly visible, but it never shows a trace of greenish. I therefore prefer not to accept colour forms of chrysitis till more is known about their nature, except the rare ones with the pure deep gold colour (disiuncta and aurea).

Plusia chryson Esper. Tijdschr. Entom. 90 : 112; Cat. VIII : (522). Na de vijf in Cat. VIII vermelde vangsten zijn slechts twee nieuwe uit ons land bekend ge- worden. Erg toegenomen is de neiging om tot in Nederland door te trekken dus niet. Uit Denemarken en het omringende Duitse gebied zijn in de literatuur geen nieuwe meldingen te vinden. Wel werd de vlinder weer aangetroffen in het zuiden van Belgisch Luxemburg: Ethe-Laclaireau (1939), Virton (1963), Buzenol (twee exemplaren in 1963). In het groothertogdom zelf werd in 1951 een exemplaar in de onmiddellijke nabijheid van de hoofdstad gevangen.

Van de verbreiding in het zuiden van Groot-Brittannié geeft HAGGET het vol- gende overzicht: zeer verbreid in het zuiden en oosten van Engeland en het zuiden van Wales tot in Cardiganshire toe. Een van de beste lokaliteiten is op het ogen- blik de Test Valley in Hampshire (Proc. Trans. South London ent. nat. Hist. Soc. 1957 : 94—95, 1958).

De in ons land waargenomen vliegtijd ligt nu tussen half juli en eind augustus (16.VII—27.VIIT).

Chrysoptera Latreille

Chrysoptera c-aureum Knoch. Tijdschr. Entom. 90 : 121; Cat. VIII: (531). De vlinder is zonder twijfel inheems en komt lokaal vooral op moerassige plaatsen verspreid in het land voor. Hij komt goed op licht, maar is spoedig min of meer afgevlogen. Het zoeken van de rupsen is echter niet zo eenvoudig. Zie hiervoor G. DIJKsTRA in Ent. Ber. 21 : 182, 1961.

De vliegtijd kan al in de eerste helft van juni beginnen en voortduren tot half augustus. De uiterste data zijn nu: 10.VI—15.VIII.

Polychrisia Hübner

Polychrisia moneta Fabricius. Tijdschr. Entom. 90 : 120; Cat. VIII: (530). Het voorkomen van de vlinder hangt af van de aanwezigheid van ridderspoor en monnikskap in tuinen. In de regel is het dier vrij schaars, althans op licht, in sommige jaren echter veel talrijker. Zo was de eerste generatie in 1956 talrijk te Bennekom, de tweede in 1953 (VAN DE Por). LEFFEF vermoedt, dat de vlinder vooral in de schemering vliegt en dan bloemen bezoekt, zodat hij schaarser lijkt dan hij in werkelijkheid is (in litt.). De rupsen zijn in elk geval niet zelden in het voorjaar op de voedselplanten in aantal te vinden.

In het Waddendistrict is de soort nu van één van de eilanden bekend. Interes- sant is, dat het eerste exemplaar voor Ierland pas in 1939 werd gevangen, het tweede in 1952 (E. S. A. BAYNES, Ent. Gazette 4 : 286, 1953).

De vliegtijd van de tweede generatie kan al half augustus beginnen (17.VII. 1943, e. l., 19.VIII.1959, wild, Lucas) en voortduren tot half oktober (14.X. 1953, Wageningen, VAN DE POL).

Variabiliteit. f. pallescens Lempke, 1949. Een enkele keer hebben exem- plaren van de tweede generatie dezelfde grondkleur als die van de eerste, maar in de regel zijn ze toch iets kleiner. Exemplaren van de eerste generatie met de lichte grondkleur zijn vermoedelijk niet al te zeldzaam. In Zoöl. Mus. nog van Apel- doorn, Twello, Hilversum, Leidschendam.

Abrostola Ochsenheimer

Abrostola trigemina Werneburg (triplasia auct. nec Linnaeus). Tydschr. Entom. 90 : 122; Cat. VIII : (532). De soort dus met (bij typische exemplaren) licht bruinachtig wortelveld op de bovenzijde van de voorvleugels en iets gegolfde tweede dwarslijn. Reeds in 1864 toonde WERNEBURG aan, dat dit niet de door Linnaeus beschreven soort is (Beitr. Schmetterl.k. 1 : 247— 248), maar pas in de moderne publicaties wordt zijn correctie toegepast (o.a. in de nieuwe editie van SOUTH).

Uit beide lijsten van vindplaatsen blijkt, dat de vlinder over vrijwel het gehele land verbreid is. Opvallend is het grote aantal nieuwe vindplaatsen in het westen. Hier en in het noorden is de soort beslist gewoner dan de volgende. In het zuiden van het land is op vele plaatsen daarentegen het omgekeerde het geval. Tot nog toe pas op één van de waddeneilanden aangetroffen.

Wat de vliegtijd betreft, zekere data van de derde generatie zijn thans: 17.1X— 10.X. De zeer late datum werd in 1962 genoteerd door VAN AARTSEN.

Abrostola triplasia L., 1758 (¢ripartita Hufnagel, 1766). Tijdschr. Entom. 90 : 123; Cat. VIII: (533). De soort met (bij typische exemplaren) licht wortel- veld en licht achterrandsveld, terwijl de tweede dwarslijn alleen iets gebogen is.

In de noordelijke helft (ongeveer tot aan de grote rivieren) is de vlinder bijna overal duidelijk minder gewoon dan de vorige soort, in de zuidelijke helft daaren- tegen is in de regel het omgekeerde het geval. Hoewel vindplaatsen op de Veluwe bekend zijn, schrijft LEFFEF me, dat hijzelf de soort nog nooit daar heeft aange- troffen, wat wel iets zegt omtrent de zeldzaamheid in dit gebied. In de hierna volgende lijst van nieuwe vindplaatsen valt ook het kleine aantal ten noorden van Ryn en Lek op (slechts één enkele op de Veluwe!). Tussen de grote rivieren wordt het al dadelijk beter (ook in het westen) en vooral Limburg komt met een lange serie goed uit de bus. Mogelijk hebben we in dit geval met klimatologische invloeden te doen.

In het Waddendistrict is ook deze soort slechts van één van de eilanden bekend.

De vlinder kan in gunstige voorjaren al in de tweede helft van april beginnen te vliegen. De vroegste datum is nu 19 april (in 1964 te Nuenen, Nets). De tweede generatie kan eveneens belangrijk vroeger verschijnen dan in 1949 bekend was. Van een op 29 juni gevonden rups kwam de vlinder reeds op 22.VII uit de pop (HUISMAN). Er zal dan ook zeer waarschijnlijk geen scherpe grens tussen beide generaties bestaan. De vliegtijd kan iets later eindigen dan in Cat. VIII vermeld is: op 11.IX.1963 nog een exemplaar te Stein (collectie Missiehuis). Duidelijke aanwijzingen van een derde generatie kan ik bij deze soort evenwel niet vinden.

Variabiliteit. HÜBNER's wrficae is niet te scheiden van de typische vorm. Alle exemplaren met min of meer wit afgezette dwarslijnen moeten hiertoe gere- kend worden.

f. plumbea Cockayne, 1947. Naast de eenkleurig donkere exemplaren komen er ook voor met even donkere voorvleugels, maar die iets van de witte tekening in wortel- en achterrandsveld bezitten. Ook COCKAYNE vermeldt zulke exemplaren. De vorm is afgebeeld op plaat 7 fig. 11. Oude Nederlandse exemplaren bestaan

278 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (928)

er niet van. Het is stellig een moderne melanistische vorm, die zich bovendien snel uitgebreid heeft. Kon in Cat. VIII nog slechts één vindplaats vermeld worden, thans zijn vooral in het zuiden en midden van Limburg tal van vindplaatsen be- kend, waaraan die in het oosten van Noord-Brabant aansluiten. Ook in Zeeland zijn al exemplaren gevangen, bovendien in Twente. Nergens is de vorm echter zo verbreid als in het zuidoosten van het land. Hier werd hij ook voor het eerst waargenomen (Valkenburg, 1910).

In het Limburgs-Oostbrabantse gebied komt de vorm thans practisch op alle vindplaatsen onder de soort voor, zodat deze niet opnieuw opgesomd behoeven te worden. Daarbuiten ken ik thans de volgende: Volthe (VAN DER MEULEN); Bennekom (Landb. Hschool); Aerdt (PEERDEMAN); Aerdenhout, Bergeijk (VAN WISSELINGH); Gorkum (BRANGER); Ouddorp (VROEGINDEWEIJ); Haamstede (Zool. Mus.); Sint Michielsgestel (KNIPPENBERG ).

CATOCALINAE Mormonia Hiibner

Mormonia sponsa L. Tijdschr. Entom. 90: 101; Cat. VIII: (511). De in 1949 gegeven verbreiding is goed. Het aantal nieuwe vindplaatsen is klein. LEFFEF schreef me enkele interessante details over het gedrag van het dier. In 1946 zag hy op klaarlichte dag twee exemplaren, die steeds maar om een middel- grote eik vlogen langs de weg van Hoenderlo naar Otterlo. Aan de stam was geen lekkende plek, zodat het niet om het sap te doen geweest kon zijn. Zijn erva- ring is overigens dat de vlinder in de schemering begint te vliegen en dan zeer schuw is. Na half elf komen de dieren goed op de stroop en zitten dan zelfs in het felle licht van een sterke lamp goed vast. Maar op menglichtlampen en kwik- damplampen komen ze maar heel zelden, evenmin trouwens als Catocala promissa.

Geen correctie op de vliegtijd, die dus blijft: 10.VII—16.IX.

Catocala Schrank

Catocala fraxini L. Tijdschr. Entom. 90 : 104; Cat. VIII: (514). De vlinder blijft een grote zeldzaamheid, die zeer onregelmatig nu eens hier, dan weer daar

(929) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 279

wordt gevangen. Ik geloof dan ook, dat hij niet in staat is zich hier te handhaven, maar dat hij steeds weer opnieuw naar ons land moet immigreren. De hiaten in de jaren van waarneming en de zeer kleine aantallen zijn hiervoor wel een sterke aanwijzing.

Merkwaardig is, dat de soort na de Tweede Wereldoorlog vaste voet in het zuiden van Engeland gekregen heeft. Zowel in Kent als in Norfolk zijn herhaal- delijk vlinders gevangen en rupsen gevonden (zie T. G. HOWARTH, 1950, Ent. Gazette 1: 41—46). De laatste jaren heb ik geen enkele melding meer in de Engelse tijdschriften gezien, zodat het de vraag is, of deze vestiging wel duurzaam geweest is.

De vliegtijd kan al in de eerste helft van juli beginnen. Reeds 10.VII.1956 werd een exemplaar te Epe gevangen. De slotdatum verschuift ook iets: de laatste dag van waarneming wordt nu 13.X (in 1953 te Bennekom).

van Apeldoorn, die bestond uit vrijwel alleen prachtige gave exemplaren, wat de indruk wekt, dat ze ook in die omgeving hun ontwikkeling doorgemaakt hadden. Maar alle pogingen de soort in latere jaren op dezelfde plaats terug te vinden, hebben tot nog toe schipbreuk geleden. Het is daarom niet uitgesloten, dat de vlinder niet in staat is zich hier te lande constant te handhaven, een conclusie, die me in 1949 ook al de meest waarschijnlijke leck.

Callistege Hübner

Callistege mi Clerck. Tijdschr. Entom. 90 : 108; Cat. VIII: (518). Van de waddeneilanden is de vlinder nu ook bekend van Vlieland (CAMPING) en Ter- schelling. Op het laatstgenoemde eiland trof LEFFEF hem heel gewoon aan, zowel in het duin als in de polders en langs de dijken. Alleen Rottum ontbreekt dus nog in de rij. Overigens is niets nieuws over de verspreiding te vermelden.

De normaal enige generatie kan nog iets vroeger beginnen te verschijnen dan in 1949 bekend was. De vroegste datum is nu 2.V (1946, Heemskerk, Lucas). Een tweede juli-vangst is 16.VII.1949 op Texel. Mogelijk was dit een vertegen- woordiger van een overigens wel erg zeldzame tweede generatie. Zeker behoorde er het exemplaar toe, dat VAN OorscHoT 30.VIII.1949 te Nijverdal ving.

Ectypa Billberg

Ectypa glyphica L. Tijdschr. Entom. 90 : 109; Cat. VIII : (519). De in 1949 aangegeven verbreiding is in grote trekken juist. De vlinder is nu van een der waddeneilanden bekend geworden. In het Hafdistrict is hij een rariteit en ook in het Duindistrict wordt g/yphica maar weinig aangetroffen. In het Fluviatiel Dis- trict komt hij meer voor. Maar opvallend is vooral zijn sterke verbreiding in het zuiden en midden van Limburg. Hier is de vlinder wel overal aan te treffen, waar voldoende klaver groeit.

De eerste generatie kan iets eerder beginnen te vliegen dan in 1949 bekend was en de tweede kan iets later eindigen. De uiterste data van beide generaties worden nu: I van 21.1V—30.VI en II van 7.VII—9.VIll. Het valt me op, dat de collectie van het Zoöl. Mus. veel meer materiaal van de eerste generatie bevat dan van de tweede. Zeer waarschijnlijk is de laatste slechts partieel.

OTHREINAE Scoliopteryx Germar

Scoliopteryx libatrix L. Tijdschr. Entom. 90 : 124; Cat. VIII: (534). De vlinder is door CAMPING op Vlieland aangetroffen, zodat hij nu van vier van de waddeneilanden bekend is. Overigens komt hij overal voor, waar maar smalbladige wilgen groeien.

De vroegste datum, waarop een overwinterend exemplaar werd gevangen, is thans 1 maart. Op die datum ving kapelaan GROENENDIJK in 1960 een prachtig Q van de f. suffusa te Willemsdorp.

Dank zij waarnemingen van LEFFEF weten we nu zeker, dat een deel van de vlinders univoltien is. In juli 1963 werden in de Rivon-vallen in de Peel zeer gave dieren aangetroffen. Deze werden alle weer losgelaten nadat ze eerst gemerkt waren door een hoek uit de achterrand van de rechter voorvleugel te knippen. In de periode van 6—16 oktober 1963 werden drie van deze gemerkte dieren terug gevangen tegelijk met vele andere exemplaren, waarvan zeker 40% verkleurd was, terwijl de rest een veel helderder tint had. In mei 1964 werd weer een gemerkt roesje in de Peel gevangen, dat dus van juli 1963 dateerde! Daarnaast zijn er natuurlijk ook veel exemplaren, die bivoltien zijn en waarvan de vele nazomer- rupsen afstammen, die nog hetzelfde jaar de vlinder leveren. Dit komt dus inder- daad vrijwel overeen met de gang van zaken als bij Aglais urticae. Alleen is het merkwaardig, dat de vlinders, die zich niet hetzelfde jaar voortplanten, blijkbaar (althans voor een deel) actief blijven, terwijl die van A. wrticae al vrij spoedig na het uitkomen in diapauze gaan.

Variabiliteit. f. pallidior Spuler, 1907. Nieuwe vindplaatsen van deze bleke vorm zijn: Denekamp, Hilversum, Weesp, Groede (Zoöl. Mus.); Rhenen (CARON); Den Haag (HARDONK).

f. suffusa Tutt, 1892. De vorm zonder een spoor van de roestrode kleur in het achterrandsveld van de voorvleugels is onder het moderne materiaal in elk geval gewoon en komt practisch overal onder de soort voor. Vaak is ook de rode kleur aan de wortel en in het middenveld gereduceerd, zodat de dieren er dan opvallend donker uitzien.

Fig. 53. Histogram van Lygephila pastinum Treitschke.

Het hierbij afgebeelde histogram (fig. 53) laat zien, dat de hoofdvliegtijd in de laatste week van juni en in de eerste twee decaden van juli valt. De vroegste vangst is een exemplaar van 3 juni 1901 te Voorschoten (in Zoöl. Mus.). De vliegtijd van de eerste generatie eindigt in de eerste decade van augustus en de grenzen ervan worden nu: 3.VI—9.VIII. De zeer partiële tweede generatie kan in de derde decade van augustus en de eerste helft van september vliegen (20.VIII— 11.IX, vers dier in 1959 te Montfort door MAASSEN, dus zeker is ook nog een latere datum mogelijk). Alleen in gunstige seizoenen is deze generatie, waarvan de vertegenwoordigers in de regel duidelijk kleiner zijn, te verwachten.

Catephia Ochsenheimer

Catephia alchymista Schiff. Tijdschr. Entom. 90: 126; Cat. VIII: (536). Toen de tekst voor Cat. VIII werd samengesteld, was juist de bloeiperiode voor de soort begonnen, die in de loop van de vijftiger jaren en het allereerste begin van de zestiger jaren zijn hoogtepunt zou bereiken, maar die sinds 1962 (voorlopig?) weer voorbij is. Of deze achteruitgang van tijdelijke aard is, zullen we moeten afwachten. In elk geval worden nu nog slechts enkele exemplaren aangetroffen op dezelfde plaatsen, waar nog maar een paar jaar geleden tientallen gevonden konden worden. Overigens is dit niet zo verwonderlijk voor een soort, die hier de uiterste grens van zijn areaal bereikt en daardoor extra gevoelig zal zijn voor ongunstige factoren, waarbij we wel in de eerste plaats aan het klimaat zullen moeten denken.

Het midden van Limburg is blijkbaar het meest ideale gebied voor de vlinder in ons land, waar het oosten van Noord-Brabant dan goed bij aansluit. In de gun- stigste periode reikte zijn areaal tot in Utrecht en Gelderland, maar uit deze pro- vincies zijn al jaren lang geen nieuwe vangsten meer gemeld.

Uit het omringende gebied zijn vrijwel geen nieuwe gegevens bekend geworden, hoewel de bloeiperiode onmogelijk tot Nederland beperkt gebleven kan zijn. Een nog niet vermelde Belgische vindplaats is Lanaeken, vanwaar zich een exem- plaar in de collectie-Rijk te Maastricht bevindt.

De vliegtijd kan tot half juli duren. De grenzen zijn nu: 27.IV—15.V1. Bovendien is een enkele maal een exemplaar van een zeer partiële tweede generatie in augustus gevangen: 11.VIII.1953 te Wageningen, augustus 1954 te Sevenum (beide in collectie-VAN DE Por). Dat we hier niet met late exemplaren van de normale generatie te doen hebben, bleek duidelijk uit een eikweek van Pijpers

Variabiliteit. Deze is zeer gering. Sommige exemplaren zijn op de voorvleugels wat bonter getekend dan de meerderheid der exemplaren, maar een duidelijke afgrenzing van een bepaalde vorm is niet te geven.

Laspeyria Germar

Laspeyria flexula Schiff. Tijdschr. Entom. 90 : 130; Cat. VIII : (540). De in Cat. VIII gegeven verspreiding is goed. Van diverse plaatsen op de zandgronden wordt de vlinder als gewoon gemeld. In het Hafdistrict is hij tot nog toe vrijwel nergens aangetroffen. Opvallend zijn de vindplaatsen in het Fluviatiel District. Ook is flexula nu bekend van twee van de waddeneilanden.

De vliegtijd kan wel een week eerder beginnen dan in 1949 bekend was. Ook de laatste datum schuift iets op. De grenzen zijn nu: 6.VI (in 1959 genoteerd door Lucas) tot 17.VIII (in 1955 te Apeldoorn, SOUTENDIJK). Heel zelden komt toch ook bij ons een exemplaar voor van een zeer partiële tweede generatie. Hier- toe moet een gaaf dier behoord hebben, dat GORTER in de warme zomer van 1947 op 15 september te Zeist ving.

Colobochyla Hübner

Colobochyla salicalis Schiff. Tijdschr. Entom. 90 : 131; Cat. VIII: (541). De vlinder is vooral verbreid in het zuiden en midden van Limburg en de ooste- lijke helft van Noord-Brabant en is daarnaast ook aangetroffen op verschillende plaatsen in Gelderland (vooral in de Achterhoek) en in Twente. In het eerstge- noemde gebied is hij plaatselijk gewoon, zoals uit de recente inventarisaties voor het Rivon door LEFFEF is gebleken. Hij vond de rupsen in de Peel op Populus tremula!

In het omringende gebied is salicalis nu ook bekend van het Deense eiland Lolland en van enkele plaatsen in Sleeswijk-Holstein en aangrenzend gebied (zie Mitt. faun. Arb.gemeinsch. Schleswig-Holstein, Hamburg u. Lübeck N.F. 4 : 52, 1951; 5 : 44, 1952). Vlak over de grens bij Sittard ving CLAASSENS de vlinder in 1954 te Susterseel.

Er is slechts één generatie, die van de tweede helft van mei tot begin augustus kan voorkomen (20.V—1.VIII). De hoofdvliegtijd ligt tussen begin juni en de eerste helft van juli, al naar gelang het seizoen.

Parascotia Hübner

Parascotia fuliginaria L. Tijdschr. Entom. 90 : 127; Cat. VIII : (537). Uit de combinatie van de beide lijsten van vindplaatsen blijkt, dat de vlinder vooral ver- breid is in de zandstreken van het oosten en het zuiden van het land. In het Haf-

district ontbreekt hij vrijwel volkomen, terwijl hij in het Duindistrict slechts zeer

plaatselijk is aangetroffen. Opvallend zijn de vondst op één van de waddeneilan- den en de vindplaatsen in het westelijk deel van het Fluviatiel District. Over het algemeen is het dier vrij schaars.

De vliegtijd kan iets vroeger beginnen dan in 1949 bekend was en voortduren tot eind augustus (26.VIII.1948 te Aalten, VAN GALEN, 28.VIII.1941 te Benne-

(939) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 289

kom, VAN DE Por), zodat de uiterste data nu worden: 23.VI (in 1947 te Ben- nekom, VAN DE Por) tot 28.VIII. Bovendien komen in biezonder gunstige seizoenen soms enkele exemplaren voor, die tot een partiële tweede generatie moeten behoren: 3.IX.1956, vers exemplaar te Aalten (VAN GALEN), 5.IX.1959, vers klein & te Montfort (MAASSEN), 3.X.1956 een exemplaar te Aalten (VAN GALEN).

In Ent. Ber. 25 : 152 (1965) geeft ELFFERICH een beschrijving van een ab ovo- kweek met foto's van de verschillende stadia. De grote moeilijkheid is het juiste vochtgehalte van de lucht, waarbij de Polyporus (of Polysticcus, de twee hoofd- voedselplanten) niet mag verschrompelen, maar ook niet mag schimmelen. Een uitvoerig artikel over de biologie (en de verspreiding in Groot-Brittannië) publi- ceerde H. D. SWAIN in Ent. Gazette 1 : 186—200 (1950).

Variabiliteit. f. variegata Lempke, 1949. Een exemplaar van de bonte vorm met licht achterrandsveld van de voorvleugels werd nog gevangen te Zeist (GORTER). Een fraai bont exemplaar van Aarle-Rixtel (PEERDEMAN) is afgebeeld op plaat 7, fig. 12.

In both cases the name is preoccupied, so that it cannot be used to designate this dark form).]

Phytometra Haworth

Phytometra viridaria Clerck. Tijdschr. Entom. 90: 128; Cat. VIII: (538). De voedselplant van de rups, de vleugeltjesbloem (Polygala vulgaris L.), groeit volgens de flora van HEIMANS, HEINSIUS en THIJSSE in de duinen, op lichte plaatsen in bossen en langs beschaduwde zandwegen en daardoor is de verbreiding van de vlinder in ons land ook tot dergelijke terreinen beperkt. Een enkele Zuid- limburgse vindplaats zou er op kunnen wijzen, dat de rups daar op de alleen in dat gebied voorkomende Polygala comosa leeft. Het gewoonst is viridaria in de duinen, vooral op enkele der waddeneilanden. Hier is de soort nu alleen nog niet op Texel en Rottum aangetroffen. In het binnenland is hij lokaal en vrij schaars.

Fig. 54. Histogram van Phytometra viridaria Clerck.

De vangdata van alle exemplaren, die ik kon achterhalen, zijn in het histogram (fig. 54) verwerkt. Daaruit blijkt duidelijk, dat de soort twee generaties heeft. De eerste kan al omstreeks half april verschijnen, maar de hoofdvliegtijd valt in de tweede en derde decade van mei met enkele nakomers in de eerste en tweede decade van juni. De uiterste data ervan zijn nu: 17.1V—17.VI.

De tweede generatie, die gewoner is, begint eind juni te vliegen. De hoofd- vliegtijd ervan valt in juli en begin augustus en nakomers rekken het soms tot de laatste week van augustus. De uiterste data zijn nu: 30.VI—27.VUI.

(941) B. J. LEMPKE: Catalogus der Nederlandse Macrolepidoptera 291 Rivula Guenée

Rivula sericealis Scopoli. Tijdschr. Entom. 90: 129; Cat. VIII: (539). CAMPING trof de vlinder ook op Vlieland aan, zodat hij nu van drie van de waddeneilanden bekend is. Overigens is niets biezonders over de verspreiding te vermelden.

De vliegtijd kan al aan het begin van de derde decade van mei beginnen. De vroegste datum is nu: 21.V, in 1953 te Bennekom (VAN DE POL). In gunstige herfsten kan de vlinder nog tot in de tweede helft van oktober voorkomen en vliegt dan ongetwijfeld in een partiéle derde generatie, daar deze late exemplaren verse dieren zijn. Tweede en derde generatie gaan dan zonder grens in elkaar over, zoals blijkt uit de volgende waarnemingen van Lucas: 3.X.1959 een afge- vlogen exemplaar (laatste datum van de tweede generatie), maar 10.X.1959 een vers dier; ook 3.X.1962. Andere late data zijn: 11.X.1947 te Aerdenhout (VAN WISSELINGH), 13.X.1953 een vers exemplaar te Bennekom (VAN DE POL), 17.X.1959 te Hendik-Ido-Ambacht (BOGAARD), 20.X.1958 te Stein (slotdatum van de derde generatie, collectie Missiehuis).

Herminia Latreille

Herminia barbalis Clerck. Tijdschr. Entom. 90 : 137; Cat. VIII : (547). Geen nieuwe gegevens over de verspreiding, wat dus ook inhoudt, dat de vlinder nog niet op de waddeneilanden is aangetroffen.

De vliegtijd kan iets eerder beginnen dan in 1949 bekend was en later eindigen. De uiterste data zijn nu: 20.V—14.VII. Op de vroege datum werd in 1919 te Helmond een exemplaar gevangen (collectie-KNIPPENBERG), terwijl de laatste in 1956 door Lucas genoteerd werd.

Zanclognatha lunalis Scopoli, 1763 (tarsiplumalis Hübner, [1796}). Tijdschr. Entom. 90 : 132; Cat. VIII : (542). De vlinder behoort zonder twijfel tot onze lokale soorten, wat wel heel duidelijk gedemonstreerd wordt door het geringe aantal nieuwe vindplaatsen. Behalve op de zandgronden komt hij ook in het Krijtdistrict voor, maar dan toch wel bij voorkeur in bosachtig terrein.

Ons land ligt in het grensgebied van het areaal. Uit Denemarken is slechts één 9 bekend, dat in 1946 op Falster gevangen werd. In het noordwesten van Duits- land en op de Britse eilanden komt de soort niet voor.

Een zeer kleine correctie op de vliegtijd, waarvan de uiterste data nu worden: 3. VI—13.VIII.

Vindplaatsen. Fr.: Leeuwarden, Ternaar, Beetsterzwaag, Wolvega. Ov.: Volthe, Rectum. Gdl.: Wiessel. Utr.: Amerongen, Maarsseveen. N.H.: Aerdenhout. Z.H.: Oegstgeest, Den Haag. Zl: Burgh, Haamstede, Westenschouwen. Lbg.: Sevenum, Epen, Vijlen.

Variabiliteit. f. brunnescens Lempke, 1949. De lichtere vorm met bruinere grondkleur werd nog aangetroffen te: Apeldoorn, Bentveld, Aerdenhout (VAN WISSELINGH).

Zanclognatha tarsicrinalis Knoch. Tijdschr. Entom. 90 : 133; Cat. VIII : (543). De in 1949 gegeven verbreiding is goed. Uit de combinatie van beide lijsten van vindplaatsen blijkt duidelijk, dat de soort het meest verbreid is in het zuiden en midden van Limburg. Meer noordelijk wordt hij steeds zeldzamer, hoewel hij nu toch ook uit Friesland en Drente bekend geworden is. In het Duindistrict komt de vlinder blijkbaar slechts zeer spaarzaam voor. De vindplaats Hilversum moet vervallen (onjuiste determinatie).

Ons land ligt aan de noordgrens van het areaal. Pas in 1918 werd de soort voor het eerst in Denemarken gevonden. Hij is er nu bekend van Lolland, Falster, Mon en Bornholm. Eerst na de Tweede Wereldoorlog werd tarsicrinalis in Holstein, bij Hamburg en in Oldenburg aangetroffen, terwijl in 1965 voor het eerst een exem- plaar op de Britse eilanden werd gevangen, nl. in Suffolk (zie E.

Zanclognatha grisealis Schiff. Tijdschr. Entom. 90 : 134; Cat. VIII : (544). In het Waddendistrict is de vlinder nu bekend geworden van Terschelling (enkele exemplaren, LEFFEF). Ook werd hij nog op een paar plaatsen buiten de zand- gronden aangetroffen: Sexbierum (STOBBE, 1963 en 1964, mogelijk zwervers van Terschelling), Heteren en Melissant (HUISMAN), Amsterdamse Bos (Zoöl. Mus.), Woerdense Verlaat (1960, VAN AARTSEN), Leiden (Lucas), Rotterdam (Kra- lingerhout, VAN DER AA), Bolnes (gewoon !), Hendrik-Ido-Ambacht (BOGAARD).

De eerste generatie kan iets vroeger beginnen te vliegen dan in 1949 bekend was: 17.V (in 1959 genoteerd door Lucas), terwijl de tweede tot in oktober kan doorvliegen (7.X.1962, VAN AARTSEN, ook 3.X.1962, Lucas). LEFFEF heeft deze tweede generatie geregeld van 1951 tot 1958 te Apeldoorn en Wiessel waar- genomen. Gemiddeld zijn de exemplaren ervan kleiner dan die van de eerste.

Variabiliteit. f. clara Lempke, 1949. Deze lichtere vorm komt wel op de meeste plaatsen onder de soort voor, maar is niet gewoon.

Trisateles Tams

Trisateles emortualis Schiff. Tijdschr. Entom. 90 : 132; Cat. VIN: (542). De vlinder komt in hoofdzaak op de zandgronden en in het Krijtdistrict voor, vooral in bosachtig terrein. Hij is nu ook van twee van de waddeneilanden bekend. Plaatselijk kan hij gewoon zijn, wat vooral gebleken is door het faunistische onder- zoek van het Rivon, waarvan LEFFEF mij de resultaten meedeelde. Opmerkingen achter sommige vindplaatsen over de mate van voorkomen zonder verdere aan- duiding zijn van hem afkomstig. De vangst op de ene plaats in het Fluviatiel District zal wel van een zwerver geweest zijn.

Merkwaardig is de sterke achteruitgang van de soort in Groot-Brittannié. De laatste vangst dateerde daar uit 1859. Pas in 1962 werden weer vijf exemplaren in Buckinghamshire gevangen (Proc. Trans. South London ent. nat. Hist. Soc. 1962 : 35, 1963).

De laatste zekere datum van de eerste generatie is nu 21.VII (in 1958, Missie- huis Stein), die van de tweede 7.IX (LEFFEF), terwijl een exceptioneel laat exem- plaar op 4 oktober 1950 te Brunssum werd gevangen (DELNOYE). De vliegtijden worden nu dus: generatie I van 18.V—21.VII en generatie II van 23.VII—4.X.

Paracolax Hübner

Paracolax derivalis Hübner. Tijdschr. Entom. 90: 136; Cat. VIII: (546). Slechts een enkele vangst, blijkbaar van een zwerver, is bekend geworden buiten de in 1949 aangegeven biotopen. De vlinder is nu aangetroffen op twee van de waddeneilanden.

De vliegtijd kan tot eind augustus duren. De grenzen ervan worden nu: 16.VI— 28.VIII. De laatste datum werd in 1955 te Epen genoteerd door VAN WISSE- LINGH.

Van de nieuwe vindplaatsen zijn vooral de twee in het Noordhollandse duin- gebied een verrassing. Zij kwamen te voorschijn bij het faunistische onderzoek door het Rivon (opgaven van LEFFEF). Vaccinium, de voedselplant van de rups, komt bij Schoorl voor, maar niet bij Overveen (mededeling van Dr. G. KRUSE- MAN). Op de eerstgenoemde vindplaats kan de vlinder dus inheems zijn, maar die van Overveen zal wel een zwerver zijn. Opvallend is ook de vangst in twee opeen- volgende jaren op Terschelling. Hier groeit Vaccinium genoeg, maar de vindplaats ligt wel erg excentrisch. Het voornaamste biotoop wordt gevormd door groeiplaat- sen van bosbes onder grove den (LEFFEF).

De vliegtijd kan tot ver in de tweede helft van augustus duren en wordt nu: 27.V—23.VII. Op de late augustus-datum werd in 1952 door S. R. DIJKSTRA nog een exemplaar bij Voorst gevangen. Ik zelf ving op 18 en 22.VIII.1955 te Wiessel enkele afgevlogen exemplaren.

Hypena Schrank

Hypena rostralis L. Tijdschr. Entom. 90 : 140; Cat. VIII : (550). Behalve op Texel en Schiermonnikoog is de vlinder nu ook tijdens het Rivononderzoek in 1956 op Terschelling aangetroffen (LEFFEF). Overigens is de in 1949 aangegeven verbreiding wel juist, maar het is wel de ervaring van vrijwel alle verzamelaars, dat het dier beslist niet talrijk te noemen is. Dit blijkt ook wel hieruit, dat ik na

298 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (948)

1949 betrekkelijk weinig nieuw materiaal gezien heb. Opvallend is de vindplaats Hendrik-Ido-Ambacht, waar in 1956 en 1958 telkens één exemplaar werd gevan- gen (BOGAARD).

Geen correctie op de aangegeven vliegtijd.

Variabiliteit. f. vittatus Haworth, 1809. De vorm komt vrijwel overal onder de soort voor, zodat geen vindplaatsen meer opgegeven worden.

Teratologisch exemplaar. Linker vleugels te klein. Hollandse Rading (Zoöl. Mus.).

Hypena obesalis Treitschke. Van deze vlinder, die in 1963 voor het eerst in ons land werd aangetroffen, zijn nu twee in Nederland gevangen exemplaren bekend. Ongetwijfeld hebben we met een overigens op onze breedte zeldzame immigrant te doen, vrij zeker uit zuidelijker gebieden.

Uit Denemarken is één exemplaar bekend, dat in 1911 op het eiland Mors (in de Limfjord, ten noorden van Jutland) werd gevangen. Geen enkele melding uit het omringende Duitse gebied. Evenmin uit Belgié. (In Frankrijk van de Basses Alpes in het zuiden tot de Vogezen, hoofdzakelijk in bergstreken. Cf. LHOMME, Cat. Lép. France et Belgique : 336—337). Eén exemplaar in 1908 in het zuiden van Engeland.

Het ene exemplaar werd begin juni, het andere in de tweede helft van augustus gevangen.

Vindplaatsen. Ov.: Abdij Sion, begin juli 1963 (Pater AMADEUS ALMA). Z.H.: Oostvoorne, 23.VIII.1964 (VAN DER MADE c.s.).

Hypena proboscidalis L. Tijdschr. Entom. 90 : 139; Cat. VIII: (549). De vlinder is nu ook bekend van Terschelling en Vlieland, zodat alleen Ameland en Rottum nog in de rij van de waddeneilanden ontbreken. Overigens is de in 1949 gegeven verbreiding correct.

De eerste generatie wordt omstreeks half juli nog slechts sporadisch waargeno- men. De enige waarneming, behalve de twee in 1949 vermelde data 10.VII en 17.VII, is 9.VII.1959 (Lucas). De tweede generatie kan tot ver in oktober vliegen,

(949) B. J. LEMPKE : Catalogus der Nederlandse Macrolepidoptera 299

zoals blijkt uit de volgende data: 13.X.1953 (KNIPPENBERG), 14.X.1962 (Lucas) en 18.X.1962 (LEFFEF).

Variabiliteit. f. bilineata Lempke, 1949 (brunnea-bilineata Lempke, 1949). Exemplaren zonder golflijn op de voorvleugels zijn niet zeldzaam. Als vrijwel altijd heeft de tekening geen relatie met de grondkleur, zodat het niet nodig is de diverse mogelijkheden door aparte namen te onderscheiden. Nieuwe vindplaatsen zijn: Vollenhove (WINTERS); Apeldoorn, Wiessel, De Steeg, Nij- megen, Muiden, Weesp (Zoöl. Mus.); Middelie (DE BOER); Vogelenzang (VAN WISSELINGH); Oegstgeest (KAIJADOE); Kerkrade (LUCAS).

f. obsoleta Lempke, 1949. Apeldoorn, Soest, Muiden, Weesp (Zoöl. Mus.) ; Zeist (GORTER); Amsterdamse Bos (PEERDEMAN); Nuenen (VERHAAK).

f. infuscata Spuler, 1908. Deze donkere vorm blijkt nu vrij gewoon te zijn, zodat het zelfs overbodig is er vindplaatsen van te vermelden.

Dwergen. Noordlaren, Heemstede (VAN DE PoL); Hendrik-Ido-Ambacht (een extreem klein exemplaar, BOGAARD).

Schrankia Hübner

Schrankia taenialis Hübner. Tijdschr. Entom. 90: 143; Cat. VIII: (553). De vlinder blijft tot nog toe een lokale soort, die nog steeds niet uit het westen van het land bekend is. Ongetwijfeld zal hij net als de beide volgende soorten vaak voor een micro aangezien worden, zodat hij in werkelijkheid wel minder zeldzaam zal zijn dan lijkt.

De eerste generatie verschijnt al in juni. De vroegste datum is nu 8.VI (in 1964 te Ommen, BENTINCK), terwijl de laatste zekere datum 2.VIII is (in 1954 te Eperheide, van WISSELINGH). De hoofdvliegtijd is in elk geval de maand juli. Mogelijk begint de tweede generatie reeds half augustus te vliegen. Het is ten- minste te betwijfelen, of een exemplaar van 18.VIII (in 1964 te Ommen, BEN- TINCK) nog tot de eerste generatie behoort.

Vindplaatsen. Ov.: Ommen (1964, BENTINCK), Volthe (1943, VAN DER MEULEN, blijkens de vele notities in de cartotheek van KNoop hier niet zeldzaam). Utr.: Amerongen (1964, BENTINCK); Botshol (WOLSCHRIJN). Lbg.: Sevenum (1964, enkele exemplaren tijdens de Rivon-inventarisatie, LEFFEF); Bunde (1964, Lucas); Eperheide („bepaald niet zeldzaam,

vooral in de eerste helft van juli op stroop’, VAN WISSELINGH); Epen (1952, BENTINCK, 1957, Lucas).

f. obscura nov. Grondkleur van de voorvleugels zwartgrijs, die van de achter- vleugels donkergrijs. Epen, 9, 16.VII.1964 (holotype, VAN WISSELINGH).

[Ground colour of the fore wings black-grey, that of the hind wings dark-grey.]

[Upper side fore wings: central area dark, basal and outer areas pale.]

Schrankia costaestrigalis Stephens. Tijdschr. Entom. 90: 144; Cat. VII: (554). In elk geval veel verbreider dan de vorige soort, mogelijk op de meeste moerassige terreinen te verwachten; plaatselijk zeer gewoon en zelfs van een van de waddeneilanden bekend.

300 TIJDSCHRIFT VOOR ENTOMOLOGIE, DEEL 109, AFL. 9, 1966 (950)

Tholomiges Lederer

Tholomiges turfosalis Wocke. Tijdschr. Entom. 90 : 145; Cat. VIII : (555). Slechts enkele nieuwe vindplaatsen kunnen aan de in 1949 vermelde toegevoegd worden, die een kleine uitbreiding van het in ons land bekende areaal betekenen.

De vlinder kan tot in oktober vliegen. De laatste datum wordt nu: 6.X (in 1964, VAN AARTSEN), zodat er ongetwijfeld twee generaties kunnen voorkomen. De grens ertussen is echter op het ogenblik nog moeilijk aan te geven door te weinig gegevens.

Vindplaatsen. Fr.: Eernewoude (1955, CAMPING); Nijetrijne (1959, G. DIJKSTRA en CAMPING). Z.H.: Woerdense Verlaat (1959, VAN AARTSEN, in Zoöl. Mus.).
