These number twenty-eight species, of which eight are introduced as new. Two further species are placed in synonymy. ACKNOWLEDGEMENTS MY thanks are specially due to Mr A. W. Stelfox of Newcastle, Co. Down, N. Ireland for having lent me some years ago his collection of Microplitis, now the property of the U. S. National Museum. I wish to thank also the following gentlemen for the loan of material : — Dr Miroslav Capek of the Forest Research Institute, Banska Stiavnica, Czechoslovakia, Dr Max Fischer of the Naturhistorisches Museum, Vienna and Dr Wolter Helle"n of the Helsinki Museum, Helsinki. The genus MICROPLITIS Forster In my revision of the Microgasterini I included Microplitis in my key to genera (1965 : 15) and made a brief reference to it on page 7. I made no attempt to split the genus into species-groups, though I remarked that this would need to be done eventually. I have not considered it either appropriate or practical to adopt such a course in this paper for the reason that the few species discussed, coming from a relatively small geographical region, do not cover the wide range of structure permitted by the generic definition of Microplitis. Being based solely on material I have had before me, the paper contains no reference to published host-records, since it is rarely possible to be certain, from the literature, what species of Microplitis is being referred to. Nothing, as far as I can discover, seems to be known about the complete annual life-cycle of the species occurring in N. W. Europe. Information is particularly needed not only about the range of hosts that the parasites may use at one time, but also what lepidoptera will be attacked when the next generation of parasites emerges. 4 G. E. J. NIXON Some species emerge when the host in which they have developed is no longer available at a suitable stage for parasitization. For example, sordipes leaves its winter cocoon in the spring, its hosts being acronyctid larvae parasitized the previous autumn. The cocoon, described in the text, is very characteristic in appearance. Now specimens of Microplitis, bred during the summer months from various hosts but spinning a cocoon quite different from that of sordipes, seem to be inseparable from this species. I am therefore suggesting that sordipes makes two kinds of cocoon, a tough, cryptic one in which to pass the winter and a simple one, thinner in texture and of generalized form, on emergence from its summer hosts. This view is supported by the available information. I am not at all satisfied that I have been able to define clearly the limits of some of the species, for example, viduus and ruricola, mediator and tuber culif era. These two pairs of species are still in need of study. With few exceptions, among them sispes, spinolae, xanthopus and ocellatae, species of Microplitis, as far as my own experience allows me to judge, can be determined only by rather subtle combinations of characters. In my companion paper on Microgaster (1968), I was able to announce that I had discovered several useful characters that could be used in the separation of species of that genus. Microplitis has proved more resistant and I have been able to find only one new character and this, I think, has no more than species-group value. This structure is referred to as a ' hair-line ' ; it is composed of a fine, raised line running longitudinally along the inner side of the hind femur, somewhat nearer to its dorsal than its ventral edge. Usually this raised line or ridge is beset along its whole length with a row of minute setae ; adjacent to it and parallel with it along its dorsal side are frequently two or three finer ridges. This structure is by no means always well defined. It seems to occur in the solitary species and is certainly absent in the majority of those species that I definitely know to be gregarious.

Wings often almost uniformly hyaline ; if the fore wing shows faint infuscation, then it is still strikingly paler than that of the related tristis. Head, seen from above, rather deep from back to front ; its upper surface evenly and, for the size of the insect, rather strongly rugose. Flagellum rather thick, somewhat smooth- looking towards apex ; preapical segment from one and one third to one and a half times longer than wide. Mesoscutum more strongly sculptured than in aduncus, a species of similar size ; its sculpture neither weak nor strong and hence not at all characteristic. Scutellum becoming strongly shining over most of its median surface and only vaguely sculptured.

A gregarious parasite, spinning a loose heap of brown, unribbed cocoons. This species is largely characterized by the broad, bicoloured stigma and the general appearance of the 1st tergite. Another feature of some assistance in iden- tification is the dull, reddish or dingy yellow hind tibia with its complete absence of apical infuscation. The male differs from that of aduncus in not having the head widened behind the eyes. Microplitis aduncus Ruthe (Text-fig. 27) Microgaster aduncus Ruthe, 1860 : 129.

What characterizes it is not easily put into words, though size, long flagellum of female, shape of first tergite and especially the shortness of the ist abscissa of the discoideus all play a part. In general facies, the species is like tuberculifera and mediator but in having stronger mesoscutal sculpture approaches the viduus-ruricola complex. It is noteworthy that all the material available is from mountainous regions in Central Europe. Microplitis trochanterata Thomson (Text-fig. 15) Microplitis trochanterata Thomson, 1895 : 2249. <$ 9- This species is essentially characterized in both sexes by the narrow, parallel-sided, strongly rugose petiole ; the rugosity of the petiole has a charac- teristic evenness. The unusually small vannal lobe of the hind wing is also a feature (Text-fig. 15) ; the anal vein reaches very distinctly beyond the middle of the vannal lobe. In 25 Swedish males examined, the hind femur, with two exceptions in which it is flushed with red along sides, is entirely dark brown ; the middle femur is usually sharply darkened on about basal half. Palpi infuscate, never yellow as in mediator. Unlike calcarata, the mesoscutum along the course of the notaulices and within a large, posterior area, shows an intricate rugose-reticulation ; the granulate sculp- ture, so much a feature of calcarata, is absent in trochanterata. The general appearance of the petiole is remarkably constant in all specimens examined, of both sexes. 9. Striking on account of the appearance of the antenna ; the flagellum is thick, rather short, the first 8-9 segments bright yellowish ; the preapical segment is about one and one third times longer than wide ; scape dark brown. Hind femur with more or less distinct hair-line, bordered anteriorly by 2-3 delicate striations. SWEDEN : various localities in Skane, 25 , bred 25^.1915. All females recorded as having been bred from Euclidia mi differ slightly from fordi in that the preapical segment of the flagellum is always fully twice as long as wide. The ocelli, too, are placed slightly further from the eye, the distance between a posterior ocellus and the eye-margin being slightly greater than twice the diameter of the posterior ocellus ; in fordi, this distance is generally slightly less than twice the diameter of the posterior ocellus. The cocoons of specimens from Euclidia mi are exactly like those of fordi from Chesias rufata. It is possible that fordi parasitizes Euclidia mi as well as Chesias rufata in late summer, though I do not rule out the possibility that two very closely related species may be involved. I should incline more to this view were it not for certain females of fordi bred from Chesias that approach very closely these specimens from Euclidia mi in respect to the two characters mentioned above. Lyle, who named the specimens he had from Euclidia mi as viduus Ruthe (1914 : no page number) states that the parasites spend the winter in the larval state within their cocoon and emerge in April and May. This being so, the host Chesias legatella would be available to them. Males of Microplitis are always difficult to identify but I think I have correctly named the two from Scotland. Their having been bred from Thera juniperata indicates that there is still much to be clarified concerning the range of hosts of fordi. Microplitis fordi is very close to viduus, the main difference being the pubescence of the flagellum of the female. With regard to coloration, the rather pale yellow hind tibia of fordi contrasts sharply with the black femur and is a useful aid towards recognizing the species. Microplitis sofron sp. n. A small species, similar in colour to fordi, with which it may be compared as follows :— $. Antenna rather thin with the preapical segment twice as long as wide. Raised, rugose- reticulations of the posterior part of the mesoscutum more in evidence than in fordi. Vannal lobe relatively smaller. Tergite i narrower and more obviously narrowed behind. cJ.

Cocoon rather small, evenly cylindrical, dark grey with greenish tint and without obvious ribbing ; hardly distinguishable from the cocoon of fordi from Chesias legatella but a little darker. Apart from its deceptive resemblance to eremita, strenuus is characterized by the combination of long thin flagellum and bright reddish yellow tegula. It is less heavily built and less strongly sculptured than the ruricola-viduus complex and the wings are much more nearly hyaline.

Fore wing (Text-fig. 23). Material examined. AUSTRIA : 5 <£, 2 $, all with their cocoon, bred from Litho- campa ramosa. One male and one female in BMNH ; rest in Naturhistorisches Museum, Vienna. Host : Lithocampa (now Callierges) ramosa Esper (Noctuidae). Reinhard records the host as Dryocampa ramosa. The moth occurs in Central Europe but is not known from the British Isles. The remarkable cocoon is greyish brown and appears unusually long because of a somewhat flattened, basal pad that forms an extension of the cocoon and by means of which the cocoon is fastened to a twig ; the cocoon proper bears three dark, transverse bands. A REVISION OF EUROPEAN SPECIES OF MICROPLITIS 23 The two characters that link eremita and strenuus are the yellow tegula and the long, thin flagellum. So deceptively alike are the two species that, without their cocoons, I should have regarded them as one. The seven specimens of eremita are all labelled ' Silesia '. Two are dated ' Decem- ber ' and two ' May ' and from this may be inferred, I think, that the species passes the winter in its very distinctive cocoon. The host-larva, C. ramosa, feeds in the autumn. If this host occurred in England, I should not hesitate to put forward the suggestion that a single species is present, spinning a tough, cryptic, winter cocoon (eremita) and a simple, unmodified, early summer cocoon (strenuus). How strenuus passes the winter is not yet known ; that it may parasitize an autumn feeding host related to Callierges ramosa and make a cocoon similar to that of eremita cannot be ruled out. Microplitis viduus (Ruthe) (Text-fig. 19) Microgaster viduus Ruthe, 1860 : 134. Microplitis viduus (Ruthe) Reinhard, 1880 : 358. $. The type is more than one hundred years old and is somewhat faded. The hind femur is brown but flushed with paler colouring on each side within apical half ; the hind tibia is entirely reddish yellow, without apical infuscation. Stigma evenly brown. Antennae missing. A bred series that I confidently believe to be this species (England, Bucks, Slough) differs from the type in that the stigma shows a bright yellow patch at base, covering about basal third ; the hind femur is black in all five females and the hind tibia shows weak, apical infuscation. In five females from the Eastern Mediterranean region (Greece, Cyprus, Palestine), the hind femur varies in colour from that shown by the type to entirely reddish yellow ; these females also have the base of the stigma much more extensively yellow than in the bred series from Slough but they agree with these specimens in the important antennal characters (see key) and (Text-fig. 19). Material examined. ENGLAND : Bucks, Slough, 5 $, bred viii.1939, ex larva of Hadena serena, found same month on Crepis vireus (0. W. Richards] ; Dorset, Wareham, i , 27^11.1954 (J.

Host : Hadena serena Fabr. (Noctuidae). Cocoon brown, without ribs or paler, transverse bands ; one of the cocoons is green. This species is clearly related to fordi, from which it differs in being much more heavily sculptured ; this applies particularly to the propodeum, which is much more coarsely reticulate-rugose in viduus than in fordi ; the structural details of the flagellum are abundantly different in the two species. In coloration and sculpture, viduus approaches much more closely to ruricola and here again, the only reliable differences are provided by the antenna. 24 G. E. J. NIXON I have found no satisfactory character for separating the male of viduus from that of ruricola. Microplitis ruricola Lyle Microplitis ruricola Lyle, 1918 : 132. $. Hind femur sometimes entirely bright reddish yellow ; sometimes darkened at base and apex but apparently never entirely black. Tegula black as in viduus. Stigma at most with a very faint, basal spot. As in viduus, the sternaulus in front, where it bends upwards, tends to lose defini- tion, its rugosities merging with the coarse sculpture of the mesopleurum immediately above the front coxa ; in this respect, compare strenuus. Material examined. ENGLAND : Hants, New Forest, type-series, bred from Anarta myrtilli (G. T. Lyle Coll. in BMNH). Cambridge. Herts. Kent. Surrey. GERMANY : Freiburg. Host : Anarta myrtilli L. (Noctuidae), host of type-series. Amphipyra berbera Rungs (Noctuidae) ; parasites emerged in June and July. Calophasia lunula Hufnagel (Noctuidae) in Germany. Of the type-series in the BMNH only the lectotype male has its cocoon ; this is greyish white with faint greenish tint and is similar to the nine cocoons preserved with the series of five females and four males bred from A. berbera. The only difference between this species and viduus that I think can be said really to have specific value, lies in the length and vestiture of the apical antennal seg- ments ; all other characters appear to overlap. It can be said, however, that most specimens of ruricola, whether male or female, have predominantly reddish yellow hind femora with uniformly dark stigma, while in viduus, at least in N. European specimens, the hind femur is black and the stigma shows a conspicuous yellow, basal blotch. The position is further complicated by the presence in the BMNH of a female bred from Hadena ochroleuca Esper (Eremobia o.) which has the flagellum, and colour of hind femur as in ruricola but a fairly conspicuous yellow spot at the base of the stigma as in viduus. There is also in the BMNH a male, bred from the same host, as the female, in July ; this male has the conspicuous pale spot at base of stigma as in viduus but the hind femur is predominantly reddish yellow with darkening only at base above. There is yet another male in the BMNH, bred from Anepia irregularis Hufnagel (Noctuidae), clearly conspecific with the above male but with the hind femur darkened at apex as well as at base and a much more conspicuous yellow blotch at base of stigma. These three specimens have the same kind of cocoon as the bred specimens from Amphypyra berbera and Anarta myrtilli. I am labelling them as ruricola in spite of colour gradations towards viduus. A REVISION OF EUROPEAN SPECIES OF MICROPLITIS, 25 Microplitis fumipennis (Ratzeburg) (Text-fig. 5) Microgaster fumipennis Ratzeburg, 1852 : 49. Microplitis fumipennis (Ratzeburg) Reinhard, 1880 : 358. cj ?. Tegula bright reddish yellow ; dark brownish in 2 <£, i $, from Switzerland, Valais. Fore wing strongly embrowned ; more so on proximal half than in the related sordipes, though, as in that species, with a darker cloud beneath the stigma ; stigma with or without a yellow spot at base. Hind femur reddish yellow ; hind basitarsus, at least on outer side, as reddish over basal half as the tibia. $. Middle lobe of the mesoscutum without a medial keel ; at most with a faintly raised line of rugosities. Preapical segment of the flagellum about twice as long as wide. Scutellum tending to become smooth right at middle and here with a few, ill-defined punctures. Stern- aulus very coarsely rugose and losing definition in front, its rugosities merging with those of the mesosternum anterior to it. Hind tarsus somewhat tapered towards apex ; outer spur of the hind tibia very slightly longer than the inner one. Rugosity of the second tergite generally very weak, variable and more or less absent in the male. Length : $ $, c. 4 mm ; one of the largest species. Material examined.

POLAND : 4 $, 9 <$, bred from Chamaepora auricoma, i 9» ex Acronycta rumicis. SCOTLAND : Aberdeen, i <$, i 9, bred v., ex Acronycta menyanthidis. Type in BMNH. Host : With the exception of the specimen from Burnley, this species seems to be confined to the genus A crony eta (now Apatele] and has been bred from the following species : — A. rumicis L., A. auricoma Fabr. (—Chamaepora auricoma}, A. menyan- thidis Vieweg. All the Polish specimens bred from auricoma are with their cocoons and bear various dates from October to April. These cocoons, like those of the single Irish example from rumicis and the Scottish examples from menyanthidis are large, greyish brown, with or without two or three indistinct, longitudinal ribs and un- usually broadly flattened along the side of attachment. This is certainly the tough, cryptic cocoon in which the parasite passes the winter. If the adult emerges in late spring or early summer, it presumably makes use of an alternative host before attacking its acronyctid hosts in the late summer and early autumn ; the single female from Burnley, without cocoon, suggests that this alternative host may be found among the Geometridae.

Microplitis sordipes (Nees) Microgaster sordipes Nees, 1834 : 167. Microplitis sordipes (Nees) Reinhard, 1880 : 359. $. A species characterized by the absence of sculpture over the middle part of the scutellum ; this becomes smooth, almost polished and with a few scattered punctures. Flagellum pale beneath. All the femora and tibiae bright reddish yellow ; front tarsus reddish yellow. Fore wing with a cloud beneath the stigma. Flagellum rather thick. Middle lobe of the mesoscutum with very weak, longitudinal keel. Sides of the scutellar disc with rugosity that merges very gradually into the strong costae of the lateral area.

Pygaera ana- choreta Fabr. ; Pygaera pigra Hufnagel (Notodontidae). The larvae of all these moths show a certain degree of hairiness ; this may play an important part in host-selection by the parasite. Cocoon of very characteristic appearance, rather small, barrel-shaped, grey with brown ends and a brown, medial band ; usually fastened to a thin twig. Being brown-banded, the cocoon bears a superficial resemblance to that of eremita. Although I have seen only seven cocoons of sordipes, these were all found in the autumn, with adults emerging the following spring. Their tough texture and cryptic coloration suggest an adaptation to winter conditions. I provisionally include in my concept of sordipes a series of specimens bred during the summer months that make a cocoon entirely different from that of typical sordipes. These cocoons are evenly fusiform, thin in texture, pale grey with greenish tint or, more rarely, entirely greenish. The insects emerging from them and which I am unable to separate satisfactorily from sordipes I am labelling as ' sordipes, summer generation '. The material is as follows :— CZECHOSLOVAKIA : Holic, i $, 10^.1967, ex Scopelosoma satellitia (M. Capek) ; Banska Stiavnica, i °., i6.vii-i.viii, ex Acronycta psi (M. Capek) ; Zap.

In ascribing two different types of cocoon to sordipes, I have taken a course of action that helps me out of a taxonomic difficulty but at the same time finds some support in the available information. Nevertheless, I do not exclude the possibility that I have been unable to separate two closely related species. Microplitis spinolae (Nees) Microgaster spinolae Nees, 1934 : J66. Microplitis spinolae (Nees) Reinhard, 1880 : 358. $. Basal half of ventral surface of gaster yellow. Hind femur and hind tibia entirely reddish yellow. Flagellum long, slightly tapered apically, the preapical segment fully twice as long as wide. Distribution. N. W. EUROPE and eastwards as far as PERSIA and DAGHESTAN on the material available for examination. Host unknown. This species is rather easily recognized by the antennal scrobes above being smooth and polished ; the shining, unsculptured zone sometimes reaches as far as the posterior ocelli. Once appreciated, this feature will alone separate spinolae from all the other large species of similar coloration. Microplitis capeki sp. n. (Text-figs 8, 9) $. In general body form and shape of first tergite extremely like sordipes. Fore wing to the naked eye faintly but evenly brownish ; the absence of a dark cloud beneath the stigma makes the fore wing of this species markedly different in appearance from that of sordipes. Hind femur and hind tibia entirely red. Flagellum only faintly paler beneath. In a lateral view of the head, the temple is almost angled (Text-fig. 9), a feature absent in sordipes. The polished scutellum is more broadly triangular than in sordipes and occupies virtually the whole of the disc ; in sordipes, the polished area is more narrowed behind and has a broader area of rugosity along the lateral margin. Tergite i not, or only very slightly, widened towards apex (Text-fig. 8). Length : c. 3-8 mm, a little smaller than sordipes. Type $. CZECHOSLOVAKIA : Veseli, 13^1.1954, ex Hypogymna morio (leg.

NIXON With its long thin antenna, this species is much like strenuus, but strenuus has a dull, sculptured mesoscutum and scutellum and the first tergite is slightly longer arid narrower. Microplitis xanthopus (Ruthe) (Text-fig. 28) Microgaster xanthopus Ruthe, 1860 : 147. Microplitis xanthopus (Ruthe) Reinhard, 1880 : 358. 9. Easily recognized on the characters given in the key. The flagellum is rather thick, with the preapical segment about one and a half times longer than wide. The scutellum is dull and strongly rugose all over. The 2nd tergite shows a variable amount of rugosity and in some specimens is almost absent. I > > DASYUROIDEA RECENT PERAMELOIDEA . • \\ \ ; *\\ \\ EOCENE PALAEOGENE / ' .CRETACEOUS FIG. g. A family tree of marsupials. Adapted from Ride, 1964. To agree with the text Simpson's superfamilies have been used for Ride's orders : Dasyuroidea for Mar- supicarnivora ; Perameloidea for Peramelina ; Phalangeroidea for Diprotodonta. THE AMBLYCERA 95 of the Australian marsupials was comparatively late and that it arose from an avian menoponid stock, as suggested without elaboration by Ewing, 1929. This stock might have become established on an ancestral stock of Phalangeroidea, on which superfamily the diversity took place ; the parasites now found on the other two superfamilies being due to secondary infestations. The ancestral stock giving rise to the Boopidae would have had the M-group characters (Table i) and probably most of the A-group characters now found in the Menoponidae and Boopidae. Waterhouse (1953 : 266) has shown that in Heterodoxus species (Boopidae) there is re-gurgitation of fluid from the midgut to the crop, a charac- teristic feature of the digestion of the feather-eating Menoponidae and Philopteridae, but absent in Gliricola and Damalinia, perhaps suggesting a not too distant feather- eating ancestor for Heterodoxus. 10 11 12 13 14 15 16 17 18 MENOPONIDAE M M M m m BOOPIDAE A a-d M M D A m-+ M m 1-m n LAEMOBOTHRIIDAE DAAAAmDMA AAMMmLALD RICINIDAE AALLA + D M A DAMM+ LLLD TRIMENOPONIDAE D D D a-d D L a-1 a-1 D PROTOGYROPINAE D D D D D D GYROPINAE D D A a-d a-d D a-d A A a-1 D GLIRICOLINAE D D D a-d A a-1 D TABLE i.

American marsupials giving rise to the Trimenoponidae. Perhaps part of this stock, before great divergence had taken place, became established on the New World Hystricomorph rodents, giving the Gyropidae ; secondary infestation by Trimenoponidae on this group of rodents would also have taken place. It can be postulated that the Hystricomorphs arrived in S. America without any Amblyceran parasites. This hypothesis would explain the presence of both Trimenoponidae and Gyropidae on the New World Hystricomorphs and the absence of members of both families on any of the Old World Mammals. The Gyropidae were also able to establish themselves on other mammals which entered S. America at a later date. Vanzolini and Guimaraes (1955) have given a full account and discussion of the distribution of the lice of South American mammals.

PARABOOPIA THE CLASSIFICATION OF THE PHTHIRAPTERA It is generally accepted that the Phthiraptera are derived from a Psocopteran ancestor but there is controversy on the relationships of the groups within the order. Konigsmann, 1960 has made a wide review of the literature and given a full discussion of the characters in which the Phthiraptera resemble the Psocoptera. He considers the Phthiraptera to be a monophyletic group and not descended from more than one Psocid ancestor. Further, he has considered in detail the evidence lor the view expressed by various authors (Harrison, 1928 ; Webb, 1946 and Hopkins, 1949) 2This is a simplified key including some of the characters used by Keler (in press) ; this author has been followed in recognizing Macrophila andPhacogalia as genera, although it is perhaps doubtful whether this serves any useful purpose. THE AMBLYCERA 97 that the Anoplura are more nearly related to the Ischnocera than either is to the Amblycera. Konigsmann considers that the evidence supports this view and that the Phthiraptera can be divided into two main groups : the Amblycera on one side and a group A on the other ; this latter group comprises the Ischnocera, Rhyncho- phthirina and the Anoplura. Additional evidence strengthening this view which has emerged from the present study is the similarity of the antennal sense organs in the species belonging to group A and their difference from those of the Amblycera and the different origins of the ' gonapophyses ' in the two groups. It seems probable that the Mallophaga (Amblycera and Ischnocera) are not monophyletic and the present nomenclature of the groups within the Phthiraptera does not therefore reflect the true state of the relationships. The most satisfactory way of amending this would be to drop the name ' Mallophaga ' and have four sub- orders within the Phthiraptera as follows : Amblycera, Ischnocera, Rhynchoph- thirina and Anoplura.

GENERIC SYNONYMY The genus Chilo was erected by Zincken in 1817, for a heterogeneous cluster of species from which Duponchel, 1836, selected Tinea phragmitella Hbn. as the type- species. Only one of the remaining originally included species (plejadellus Zck.) is now considered congeneric with the type-species. Subsequently described genera, Proceras Bojer, Borer Guenee, Diphryx Grote, Hypiesta Hmps., Nephalia Turner, Silveria Dyar and Chilotraea Kapur are considered by the present author as junior synonyms of Chilo. Proceras, erected for one species, sacchariphagus from Mauritius, was for some time included in the synonyms of Diatraea Guilding, but was removed from synonymy by Tarns, 1942. Borer was established for saccharellus , and was treated by Tarns, 1942 as a synonym of Proceras. In fact saccharellus is a junior synonym of sacchariphagus. Until 1966, Proceras was considered as a distinct genus because of the reduction of the ocelli and a good deal of detail on this subject was published by Kapur, 1950. However, in 1966, the present author synonymized Proceras with Chilo on the basis of a study of the World species of this genus. Diphryx Grote, erected for one species prolatella, from Georgia, U.S.A., proved to be the same as Chilo and prolatella synonymous with plejadellus. Nephalia, described for crypsimetalla from Australia, was sunk under Chilo in 1966 by the present author. Hypiesta, established for one species, argyrogramma from Kenya, was synonymized with Chilo in 1965 by the present author. Silveria was erected for two species, REVISION OF THE GENUS CHILO 103 hexhex and adelphilia from Mexico. Dyar selected hexhex as the type-species of Silveria. Subsequently, both species proved to be synonymous with Chilo chiri- quitensis (Z.), and consequently the genus Silveria a junior synonym of Chilo (Bleszyn- ski, 1962^ : 108, 1967 : 92). In 1950, Kapur split the genus Chilo into two genera, Chilo and Chilotraea, based on the differences in the structure of face and in fore wing neuration. However, I regard Chilotraea as a synonym of Chilo (Bleszynski, 19626 : i). The interpretation of the genus Chilo has for a long time been confused, chiefly because the taxonomy has been based on the wing venation. Dyar & Heinrich, 1927, in their revision of the American species of the genus Diatraea and allies, based on the genitalia of both sexes, write : ' The genitalia of the Crambinae offer excellent characters for the separation of species and to some extent (especially in the males) of genera. The generic characters, however, are more in habitus than definable structural differences ; and are further obscured by the fact that in the genus Chilo most of the types of the other allied genera are repeated.' This opinion was quite without foundation. In fact, Chilo and Diatraea represent two of the best defined genera, on the genitalic characters, within the subfamily Crambinae. Dyar & Heinrich did not fully understand the genus Chilo. They put one species, idalis Fernald into two genera ; the female they diagnosed as Diatraenopsis idalis (Fernald), and the male of idalis they described as a new species Chilo fernaldalis (in fact idalis is a junior synonym of Chilo demotellus Walk.), based on the difference in the size of the ocelli, which, in fact, are variable in idalis (Klots, i. 1.). The genus Diatraenopsis Dyar and Heinrich (sunk under Epina Walk, by Kapur, 1950) is very different from Chilo, as shown by the genitalia of both sexes. The first good definition of Chilo was given by Kapur, 1950, but he split this genus into two genera as mentioned above. A preliminary paper on Chilo was published in 1962 by the present author, who transferred to Chilo several Ethiopian species from the genera Argyria Hbn. and Diatraea Guild. I dealt with the Palaearctic species of Chilo in Microlepidoptera Palaearctica, 1965. A discussion of the CTwTo-complex of genera can be found in Bleszynski, 1966 : 477. GENERIC AFFINITIES AND TAXONOMIC CHARACTERS Chilo is very close to the American genus Diatraea Guild. The external appearance and general structure of the male and female genitalia are similar in both genera. Diatraea is restricted to North and South America, but is poorly represented in North America. Chilo has only four representatives in North America, and only one of these, chiriquitensis is found also in Central America. All the species of Diatraea are without ocelli, many species have well differentiated uncus (which is little modified in Chilo}, peculiar lobes on the tegumen (absent in Chilo}, tufts of hair on the second abdominal segment and on the hind tibia in males. Such tufts never occur in Chilo species. It seems that Diatraea is an American derivative of Chilo and that all the above mentioned characters of Diatraea are probably secondary features. It is 01 interest to note also that the metallic scales so often found on the fore wing in Chilo never occur in Diatraea. The most important characters distinguishing the C/w/o-complex from the closely 104 S. BLESZYNSKI allied Acigona-complex are : the presence of a saccus and pseudosaccus, the rather simple structure of the valva, the lack of a bridge linking the ostial pouch with the eighth tergite in the females and the undilated posterior apophyses. Other genera of C/w70-complex are : Leonardo Blesz., Zacatecas Blesz., Chilandrus Blesz., Myelobia H.-S., Chiqua Blesz., Malgasochilo Blesz., Epina Walk, and Japonichilo Okano. All these genera are characterized by presence of a saccus and pseudosaccus, similar structure of the male and female genitalia, and a triple frenulum in the female. Leonardo (PI. 2, fig. 3), is separated from Chilo by the position of MI in the hind wing which arises from the lower angle of cell somewhat similar to Prionapteryx Steph. and allies. The position of Zacatecas is not clear as only the female of the single species ankasokellus Viette is known. This species is charac- terized by 7^2 in the fore wing which is stalked with R& R$ and #5. R$ is always free in Chilo. Chilandrus (PI. 4, fig. 18) is distinct from Chilo by the structure of the female genitalia which are peculiar in having papillae anales transformed into a triangular organ adapted to cutting the stems of the food plant. Moreover, the apex of gnathos in Chilandrus is rounded, being always pointed in Chilo. The genus Myelobia is restricted to the Neotropical Region. The external appearance of Myelobia species often resembles that of the Sphingidae. In many respects the genitalia of the species of Myelobia are very much like those in Chilo and Diatraea but they differ in having a very peculiarly shaped uncus. In the female genitalia the ostial pouch is usually not demarcated from the ductus bursae. The latter forms with corpus bursae an elongate bag. The systematic position of the next two genera, viz. Chiqua and Malgasochilo is queer. Chiqua contains one species distributed in Peru and Bolivia. It has fully developed ocelli, convex, but rounded face, small chaetosemata, wing neuration similar to that in Chilo ; the hind wing pecten is peculiar as, instead of hairs, there are very long broad scales, and an additional row of such scales on the vein i A ; in the male genitalia the valva is much broader than in Chilo and Diatraea. Malgasochilo is known only by a single male from Madagascar. Ocelli are absent, chaetosemata reduced, face not protruding beyond eye ; R% in the fore wing is stalked with R% and R^ ; the lower part of the cell in the hind wing is long, but the upper part is much shorter than in Chilo. In the genitalia, the gnathos is broader than in Chilo, otherwise the genitalia resemble those in Diatraea. In general, Malgasochilo in the genitalia has more Diatraea than Chilo resemblance. Eschata is an Oriental genus characterized by reduced chaetosemata, presence of ocelli, wing neuration similar to that in Chilo, strong pars basalis and often numerous cornuti ; female genitalia are somewhat similar to those in Myelobia ; externally the species of Eschata are very distinct by the snow-white coloration of the fore wing and two distinct transverse fasciaes. Epina is a small American genus and Japonichilo is represented by one east Asiatic species ; both are similar to each other being characterized by very strong pars basalis in the male genitalia. Ocellus in most of Chilo species is well developed ; chaetosemata are moderate, labial palpus porrect, usually at least three times as long as the diameter of an eye, in male shorter than female ; face round or conical, sometimes with a strong ventral REVISION OF THE GENUS CHILO 105 ridge formed by clypeus ; antenna in male serrate ; frenulum in female triple ; in fore wing RI free, approximate to or coincident with Sc, R% always free, #3 and R$ always stalked, R$ always free ; MI present ; in hind wing cell closed, MI from upper angle of cell, M% present ; fore wing in most species yellow or brown, in many species with metallic scales ; discal dot often present ; median dot absent in most species ; subterminal line present in most species, median line present or absent ; no longitudinal light stripe. Male genitalia of Chilo : Uncus short and stout, sharply pointed ; gnathos as long as uncus ; uncus and gnathos do not offer specific characters ; valva rather simple, often with slight pars basalis (a process at base of costa) ; sacculus without process ; vinculum greatly elongate ; saccus and pseudosaccus well developed ; aedeagus greatly elongate with or without cornuti ; often with bulbose basal projection and ventral arm ; juxta-plate in most species with long arms, sometimes asymmetrical. Female genitalia of Chilo : Papillae anales broad with ends coalescent with each other ; posterior apophyses slender ; membrane linking eighth to seventh segment without spikes ; anterior apophyses present ; seventh sternum often with heavily sclerotized plate ; ostial pouch linked to eighth segment by a membrane ; signum present or absent, in some species two signa. Very good specific characters are offered by the shape of the face, the presence or absence of metallic scales on the fore wing, the shape of the arms of the juxta-plate and of the aedeagus, the presence or absence of the bulbose basal projection and ventral arms of the aedeagus, size of the cornuti, presence or absence of a signum and the shape of the ostial pouch ; the heavily sclerotized plate of the seventh sternum in the female often offers good specific characters, but in some species it varies considerably. The shape of the face is a relatively constant character in most species of Chilo. However, orichalcocilielhis Strand shows face variable ; it may be slightly or strongly conical, with or without a sharp point. It is interesting that the very closely allied aleniellus Strand and thyrsis Blesz. always seem to have a rounded face without a trace of a point. A few Palaearctic species have a strongly conical and pointed face plus a ventral ridge. Such a ridge occurs in many species of the genus Acigona Hon., but rarely in Chilo. The ridge may be triangular or semi- circular, but it may vary slightly in its shape in one species. As mentioned above, Kapur erected a genus Chilotraea characterized by rounded face and RI coincident with Sc in the fore wing. However, both characters have only specific value in Chilo. The position of RI may vary within an individual species. Moreover, several species, i.e. pulverosellus, agamemnon, ceylonicus have the face rounded as in Chilo, sensu Kapur and RI in the fore wing free as in Chilotraea. The presence of metallic scales in the fore wing is one of the best characters in distinguishing species of Chilo. However, it should be noted that some specimens bear only a small number of metallic scales, e.g. pulveratus Wileman & South or crypsimetallus Turner. The shape and armature of the arms of the juxta-plate are also good taxonomic characters, but are variable in some species, particularly in orichalcociliellus. It is io6 S. BLESZYNSKI worth noting that an incorrect preparation of a genitalic slide often distorts arms of the juxta-plate and may make determination difficult. The number and size of cornuti seem to be constant except in sacchariphagus and its subspecies. The presence, shape and number of signa is constant except in species which have a weakly developed signum, for example auricicilius Dudgeon. GEOGRAPHICAL DISTRIBUTION Most species of Chilo are represented in the Ethiopian and Oriental Regions. Only one species, chiriquitensis Z. is confined to the Neotropical Region, four are confined to the Nearctic Region. The Palaearctic Region has 13 species, but five of them represent the Oriental element in the Palaearctic fauna, and one species, agamemnon Blesz. invaded the Near East from East Africa. The Oriental Region is inhabited by 14 species of Chilo. The Australian Region has only three species, terrenellus Pag., louisiadalis Hmps. and crypsimetallus. C. terrenellus and louisiadalis are also known from Vulcan Island. The present centre of distribution ot Chilo, however, is the Ethiopian Region where are found 18 species, one of which, partellus, may be of Oriental origin. It is known from East Africa and the Comores. The distribution of some species may have been affected by the fact that they are notorious pests of rice, sugar-cane, maize, sorghum and other graminaceous crops, so that artificial introductions may play a role in the geographical distribution of suppressalis Walk., partellus Swinhoe, infuscatellus, and particularly sacchariphagus. The latter is widely distributed in India, China, Formosa, Malaya, Indonesia, the Philippines, but is known also from Madagascar, Reunion and Mauritius. The population occurring in Madagascar, Reunion and Mauritius is very similar to the form from Indonesia and the Philippines. So far there is no record of this species from the African continent. In recent times agamemnon spread from central to northern Israel. This species seems to be of Ethiopian origin with subsequent invasion (or artificial introduction) to Middle East. C. suppressalis, an Oriental species, with intrusion to the south-east of the Palaearctic Region, is found in rice fields in Spain and in Hawaii. BIOLOGY AND ECONOMIC IMPORTANCE The larvae of all Chilo are stem-borers. The females lay from 200 to 300 eggs on the surface of the host-plant. Copulation generally occurs at night. Eggs are often laid a few hours after copulation. The eggs develop within 4-8 days. The larva bores in the stalk, and is fully developed within about 2-3 weeks. Depending on the species and climatic conditions there are one to six generations a year. In Central Europe, there is only one generation of phragmitellus. Rivnay (1967 : 15) writes about agamemnon in Israel : ' The offspring of the September moths enter diapause in the larval stage ; some of these constitute the sixth generation, which is in hibernation. The percentage of diapausing larvae is low at the beginning of September and increases until October, except when extraordinary temperature conditions prevail.' Gupta (1904 : 796) states that the larvae of infuscatellus are very active, often dispersing themselves on their silken threads from plant to REVISION OF THE GENUS CHILO 107 plant. The larvae eat into the centre of the plant, causing the characteristic ' dead-heart ' appearance. Later the larvae bore into the stems between the nodes. Gupta also states that the larval moult takes about one hour and that the number of moults varies, increasing to 7 or 8 in larvae which had hibernated. The pupal period varies from 10-12 days in February but is reduced to 6-8 days in summer. The adults emerge in the early morning, generally before sunrise. Several Chilo species are known as notorious pests of graminaceous crops : for example, sacchariphagus, partellus, tiimidicostalis, auricilius and infuscatellus are pests of sugar-cane in Southern and Eastern Asia and Eastern Africa. Rice is mostly attacked by supressalis and partellus, but also by agamemnon. C. agamemnon, zacconius, diffusilineus, partellus and orichalcociliellus are known to attack maize. For details the reader is referred to the very extensive literature on the biology and control of Chilo. The detailed bibliography of the Chilo literature was published by Katiyar (1964).

BLESZYNSKI suggest that polychrysus comes very near terrenelhis and louisiadalis, from which it differs by the presence of the pars basalis of the valva and the lack of cornuti ; moreover, polychrysus has more strongly tapered valva, a differently shaped ventral arm of aedeagus and a smaller juxta-plate. In the $ genitalia polychrysus is dis- tinguished by the heavily sclerotized area surrounding ostium bursae. Externally polychrysus is readily separated from terrenellus and louisiadalis by the presence of metallic scales on the fore wing, the much smaller size and the yellow coloration of the fore wing. The ranges of polychrysus, terrenellus and louisiadalis do not overlap. The ranges of polychrysus and auricilius overlap in Indonesia, Thailand and Assam, India. Type material examined.

REVISION OF THE GENUS CHILO 167 in having a smaller " window " in the seventh sternum, much broader ductus seminalis and an asymmetrical, heavily sclerotized ring on the ostial pouch. The populations of aleniellus from the Democratic Republic of the Congo probably form a distinct subspecies, or perhaps they represent a separate species. Because of the variation of the female genitalia in aleniellus, sometimes it is not easy to separate some specimens of this species from those of thyrsis. The latter has the female genitalia very variable (perhaps several races are involved) as is shown in Text- figs 103, 104 and 1 06). However, the genital opening in thyrsis seems always to be larger, while being very small in aleniellus. The range of aleniellus overlaps in central Africa that of orichalcociliellus, thrysis and quirimbelhis. C. orichalcociliellus has not as yet been found in west Africa. Type material examined.

Particularly it is extremely difficult to find any diagnostic characters which would distinguish ^ of thyrsis from (3$ of zoriandellus. From aleniellus and orichalcociliellus , this species is easy to separate. C. orichalcociliellus has almost always a distinct corneous point on face ; valva is much wider and less tapered than in thyrsis, and the arms of the juxta-plate greatly differ from those in thyrsis, as is shown in the figures ; in the female genitalia of orichalcociliellus the genital opening is smaller than in thyrsis ; the plate of seventh sternum in orichalcociliellus is much shorter and accompanied by two additional small, triangular side plates clothed with spikes. The aedeagus in aleniellus has no subapical digitate process ; the left arm of juxta-plate is much longer than in thyrsis and is not terminated in a strong spine ; moreover the setae of the left arm in aleniellus are stronger and more numerous. Very close to thyrsis are quirimbellus and zoriandellus. C. quirimbellus is well characterized by the straight apical part of the right arm of the juxta-plate ; more- over, the apical spine of the left arm of the juxta-plate is relatively much longer than in thyrsis and the central part of the juxta-plate is not so strongly developed, which is well seen in the slides made in dorso- ventral aspect. The $$ of quirimbellus are very easily separable from those of thyrsis as follows : the plate of the seventh sternum has the peripheries free of spikes, which are concentrated in the central and caudal parts of the plate ; the ostial pouch has two heavily sclerotized rings which are always symmetrical ; the ostial opening is rather smaller than in thyrsis ; the plate of the seventh sternum forms two weak ridges commencing at the genital opening and running slightly obliquely cephalad. The (3$ of zoriandellus are either unknown, or they are practically indistinguishable from those of thyrsis. Both species occur in Kibwezi, Kenya, from whence come the type-specimens of zoriandellus. The $$ of zoriandellus have the caudal part of the ostial pouch broadly heavily sclerotized, the ostial pouch is always asymmetrical, and does not have another heavily sclerotized ring, which occurs in the specimens of thyrsis from Kenya ; the area covered with spikes of the seventh sternum, is in zoriandellus much smaller than in thyrsis. C. thyrsis occurs in several local forms. It maybe that more than one species is involved, but probably only biological studies will clarify this obscure problem. Type material examined. Holotype g.

Distribution. U.S.A. : New Jersey, New York, Florida, Georgia. The identity of this species has hitherto been confused. The Walker description was based on a single ^ with no locality label ; moreover the type has the abdomen missing. However, the collection of the British Museum (N.H.) contains three additional <$, two of which have no locality labels and one bears a label : ' Japan '. Hampson, 1896^ : 956, gave Japan as the distribution of demo- tellus, and his opinion was certainly based on the <$ with label ' Japan '. A comparison of the Japanese <$ with the two other $ (with no locality labels) was rather difficult as the abdomen of the Japanese <$ was partly destroyed by mildew and Dermestidae. However, a careful comparison of the structure of the face and other external characters proved that it belongs to christophi, and is specifically perfectly distinct from demotellus type and two $ with no locality labels. It is very likely that the type of demotellus and two other $ come from one locality as having similar labels and way of mounting. Finally my recent study of some <$<$ of idalis from the collection of the American Museum of Natural History has thrown some more light on this problem. I have stated without doubt that some fresh <&£ of idalis have the transverse lines in the fore wing identical with those in the type of demotellus. It is of much importance to note that such yellow lines on the grey background do not appear in any other Chilo. A comparison of the structure of the face and the genitalia of idalis and the two demotellus proved identity of both species. I am much obliged to Dr A. B. Klots with whom I have had a discussion on the problem of the synonymy of idalis. C. fernaldalis was described from three <$ syntypes of idalis. Dyar & Heinrich in the description of fernaldalis stated that ocelli are absent in idalis, but they are present in fernaldalis. In fact, the type and the paratypes of fernaldalis have small ocelli. The female of idalis has vestigial ocelli and this was probably overlooked by Dyar & Heinrich. According to opinion of Dr. A. B. Klots and on the evidence 174 S. BLESZYNSKI of the variation of other Chilo, fernaldalis is conspecific with idalis. Consequently I consider both idalis and fernaldalis as junior synonyms of demotellus. This species externally resembles somewhat phragmitellus , but is very different in the genitalia. In addition, phragmitellus has a distinct ventral ridge of the face, which is absent in demotellus. The ranges of the two species do not overlap. Type material examined, demotellus. Holotype <£. U.S.A. ' 252 ; Type ', abdomen missing, in BM(NH). idalis.

Hind wing ground colour as forewing, slightly paler at base and more greyish on inner fold ; sub-base with two fine black lines, the distal one bordering a darker brown zone which defines the inner edge of the discal band and which is again accentuated by a black line, the distal border of the band irregular, especially where it tapers to the inner fold, where it may be represented by a whitish mark ; the postdiscal zone is slightly darker in ground colour and is traversed by a series of rather ill- defined greyish olive and maroon lunules, strongest above the anal angle ; submargin with a series of greyish white lunules outlined distally in black, and represented as three black dots opposite the tails and a double spot in the anal angle ; border with greyish white lunules with orange centres as far as upper tail, then olive to anal angle ; margin darker grey to blackish, ill-defined. 202 V. G. L. VAN SOMEREN Charaxes guderiana rabaiensis Poulton (PI. i, figs 3-4, Map i) Charaxes guderiana rabaiensis Poulton, 1929 : 482. The male differs from nominate guderiana in being generally darker, with smaller and fewer spots in the fore and hind wings, and in lacking the postdiscal blue bar in the hind wing. The female has a much darker ground colour than nominate female, but the bars on fore and hind wing are paler, creamy ochre instead of orange. MALE. Fore wing length 30-32 mm ; shape as in nominate race. Upper side. Ground colour deep black, with only a slight greenish sheen at base of wing. Spots arranged as in nominate race, the subcostal spots equally large, but the spots in the postdiscal row much smaller, not extending beyond 2, rarely a vestigial spot in ib, all spots white ; marginal spots generally smaller. Hind wing usually without or with only the faintest trace of a postdiscal green-blue bar, submarginal spots much smaller ; marginal white lunules smaller, those at tails and anal angle with larger orange-bronze spots. Tails shorter. Underside. Ground colour very similar to nominate race, but basally paler, and the dark brownish band in fore wing in disco-postdiscal interspaces in more contrast. On the hind wing the postdiscal row of olive and maroon lunules stronger and more distinct. FEMALE. Fore wing length 35-40 mm. Upperside. Fore wing basal area blackish brown usually without any rufous tinge ; pattern of spots as in nominate race, but spot at end of cell often small or vestigial ; discal spots wider, more extended distad especially in ia-2, but post- discal spots smaller, all spots creamy ochre ; marginal spots smaller, less defined and paler. Hind wing basal area darker ; discal bar creamy ochre, usually wider ; submarginal spots almost obsolete ; rufous orange border strong to upper tail then olive at tails and anal angle. Underside. Much as in nominate race, but fore wing discal band stronger and wider ; tornal spots bolder. On the hind wing the creamy white band rather wider and more distinct ; postdiscal series of olive and maroon lunules more denned and distinct on a paler ground ; submarginal greyish lunules less strong. This subspecies is common in the savanna and bush-veldt and most plentiful in the Brachystegia woodlands, Miombo country. The larvae feed on Brachystegia spp. (Leguminosae). Charaxes opinatus Heron (PL i, figs 5-8, Map 2) Charaxes opinatus Heron, 1909 : 156, pi. 5, fig. 7. Charaxes opinatus Heron ; Jackson, 1956 : 65, pi. 3, fig. 5 ; pi. 4, fig. 5 ; pi. 6, fig. 4 ; pi. 7, fig. 4. This is an alpine species which is confined to the montane forests of western Uganda, and the highlands of the Kivu region. The male is one of the commonest Charaxes in the high forests of the Kigezi country, coming readily to bait (fermenting bananas) and ' droppings ' of carnivores ; but in spite of intensive trapping over several years only two females have been taken, both at Mafuga. Heron compared the species with Charaxes ethalion, and drew attention to the similarity of the underside to that of Charaxes anticlea. MALE. Fore wing length 30-32 mm. Shape not falcate. The males exhibit three forms on the upperside. Form i. Upperside. Ground colour rather a dull purplish black ; fore wing REVISIONAL NOTES ON AFRICAN CHARAXES 203 Bunia* ORIENTAL PROVINCE Beni, Ruwenzori:£-!

Hind wing ground colour as fore wing, slightly more brownish on inner fold, immaculate, except for a row of submarginal bluish linear marks with white centres, largest at hind angle to upper tail, then decreasing in size to upper angle ; margin with conspicuous brick-red border commencing just short of upper angle and extending to lower tail, then olive at anal angle ; extreme margin black with fine white fringe ; margin only slightly dentate. Tails moderately long and slender, upper 7 mm, lower 5 mm, black-edged, with red central line. Forma. This is the nominate form. Similar to form i, but with a row of dull brick-red spots in the postdiscal line on the hind wing extending from above the anal angle at 2, to the upper angle at 6, the lower marks to 4 conjoined, the rest free ; on the margin the brick-red border is more developed. Form 3. Very similar to form 2, but with a conspicuous series of brick-red linear marks in the postdiscal of the fore wing, extending from ib to 5 following the contour of the outer margin ; the spot in 5, small and set in. Hind wing as in form 2. Underside. Ground colour satiny brownish grey, the fore wing crossed by two darker brownish bands, that in sub-base broad, passing through the upper end of the cell where it is 5 mm wide, then tapering very slightly through sub-bases ib-2, the band is narrowly out- lined in black and white. A discal brown band, widest at costa and through 6-5, becomes narrower and irregular through 4-ib. Outer marginal border in curve of the wing brownish, broad at centre but tapering at both apex and tornus. Basal area of cell with three white- ringed black dots. Hind wing ground colour as fore wing, disc of wing crossed by a strong brownish band, in line with that of the fore wing, edged black and white ; the postdiscal band narrow at costa, widens in the middle area and then tapers toward the inner fold above the anal angle, where the edges are more defined ; submargin with a series of linear black marks edged whitish internally and greenish distally, spots double at anal angle ; margin with dull reddish extending from upper angle to lower tail, where the border becomes olive at the anal angle ; extreme edge fringed with reddish. FEMALE. Fore wing length 35 mm ; apex rather more pointed than male. Upperside. Ground colour black ; wing crossed by a white band, divided at costal end into discal and post- discal spots which become conjoined at 3, forming more quadrate spots and extending to the hind margin in za. No spots on margin. Hind wing ground colour black ; disc of wing crossed by a white band, commencing at costa where it is 5 mm wide, is almost parallel-sided to 2, where it tapers toward the inner fold but does not cross it. Submargin with a series of well separated linear white marks, double at anal angle and slightly blue-ringed ; margin with slight rusty lunules from upper angle to upper tail. Tails long and slender, upper 7 mm, lower 5 mm. Underside. Fore wing somewhat as in the male, slightly less satiny brown, the ground colour slightly darker ; the discal white band of upperside well represented. Hind wing basal area slightly darker, sub-basal brownish band stronger ; discal white band in strong contrast, offset by a dark postdiscal zone, the white band not crossing the fold but there represented by a greyish mark. Submarginal series of white and black lunules complete ; marginal border as in the male. Range : This species seems to be confined to the mountains of the western area of Uganda, the Kivu Mountains and is also recorded from the forests N.W. of Lake Tanganyika, no specific locality being given (Grauer). It was first taken on the eastern side of the Ruwenzori Mountains, Mubuku Valley, 5000 ft by the BM(NH) Expdt. 1905, and subsequently at the Namwamba Valley, 6500 ft, BM(NH) Expdt. 1934-35. Then there is an apparent break until one reaches the montane forests of the Kigezi area at Mafuga, Rutenga and Ruhiza, 6000-9000 ft. It is also recorded from the Niragongo forest, N.E. Kivu (T. A. Barnes).

The unique type of this species was taken by Reimer in the Mikindani area of Tanzania, which lies to the north of the mouth of the Ruvuma River on the Tan- zania-Mozambique border. It has remained the sole example of the species trom that area in spite of intensive search of recent years ; the female is still unknown. This is the more surprising since the subspecies blanda kenyae of the Kenya coast has been taken in some numbers. MALE. Fore wing length 31 mm ; shape rather falcate, though the apex of wing is rather rounded ; margin bluntly dentate. Upperside. Fore wing ground colour black, with greenish sheen at base of wing. Pattern not strong, consisting of a small obscure spot at distal upper end of cell ; four blue spots in discal line (no spot in 4), subcostal mark elongate, one below small, spots in 3 and 2 larger and more rounded ; the postdiscal series of spots are bluish white, three subapical in a line followed by spots of increasing size more or less parallel to the margin of the wing, those in ib and la more diffuse and bluish ; margin without marks except for slight white fringe between dentations. Hind wing, basal area black, shading to brownish on inner fold ; disc of wing crossed by a bluish white band, represented at subcosta by a small free spot, the rest conjoined and of increasing width to 2, then tapering toward the inner fold, where it is represented by a whitish triangular mark above the anal angle. Well separated submarginal linear marks pale blue, more purplish at anal angle ; marginal lunules present, commencing above upper tail, greenish blue to golden olive at anal angle. Margin dentate, tails long and thin, pointed, upper 5 mm, lower 6 mm, black with thin median line. Underside. Boldly patterned. Fore wing basal area greyish brown, with black spots and lines crossing the cell, one at base, a double spot beyond, followed by an angled line in subapex and a straighter line at apex continued through sub-base 3 with a line sub-base in 2. These lines define the inner edge of a darker brown bar, which in turn is accentuated by a wavy black line where it meets the discal bar ; the latter is silvery grey and rather ill-defined distally, where it borders on a broader dark greyish brown zone. It is fairly straight on its inner border but irregular on outer, where it is crossed by the postdiscal row of silvery grey spots, bordered with blackish in 2 and ib but ill-defined at upper half, where it merges into the submarginal silvery grey band. The latter is forked at the costal end, fading out at the tornus, where there is a double blackish mark ; the curved outer border of wing dark greyish brown. Hind wing basal area greyish brown to discal silvery white bar, sub-base crossed by a silvery bar outlined in black stopping short of the inner fold ; the narrow discal bar crosses the wing from the costa to inner fold, where it stops short but is represented on the inner fold by a whitish line, the inner edge of the bar accentuated by black. The outer edge merges into a dark brownish zone which carries a series of black and olive lunules extending from costa to above the anal angle ; submargin with a continuous series of whitish lunules, distally edged in black, which forms loops between the tails and at anal angle, these all have lilac centres ; admargin maroon to upper tail then golden olive, edged white, then black. Margin dentate, tails black with olive mid-line. Range : The only known locality for this race is Mikindani, north of the mouth of the Ruvuma River on the Tanzania-Mozambique border. 206 V. G. L.

FEMALE. Larger than the male, fore wing length 36-37 mm ; shape slightly less falcate. Upperside. Fore wing ground colour less intense black and with less greenish at base of wing. Pattern as in the male but all spots larger, the spots in la-ib conjoined, all spots bluish white ; some dark scaling indicating the line of junction of the two rows in 2 and ib, the mark in la a long streak. Hind wing discal patch bluish white, more strongly blue on distal border, represented at subcosta by a free white spot in the discal line and conjoined spots in the post- discal line ; submarginal spots bluish white ; admarginal angled marks somewhat orange above upper tail, then olive to tails but bronzy at anal angle. Tails long with rounded ends, upper 8 mm, lower 7 mm. Underside. Pattern essentially similar to that of male, but fore wing ground colour paler and more satiny, the silvery sub-basal area and that of the discal row of spots more distinct ; tornal double black mark strong. On the hind wing the silvery discal bar strong ; the zigzag postdiscal line of lunules stronger and the border of the wing more satiny ; the admarginal reddish lunules above upper tail strong, golden olive at anal angle with greyish blue spots outlined in black, strong. The female oviposits on Dalbergia (Papilionaceae) and also on Brachystegia spp. (Caesalpinaceae). Range : Occurs in the forests north of Mombasa ; the types are from the Sekoke forest, 1921 (van Someren), but it is now known to occur not only in the Sekoke- Arabuko forest but also in the forest patch around Gedi and Kilifi. 2. CHARAXES ACHAEMENES FELDER AND ITS SUBSPECIES A species with a very wide distribution, extending from the Natal area of South Africa to northern Ethiopia and Sudan, then westward to the West Coast. It is found in the savannah country and light woodland, wherever its food plants, Ptero- carpus spp., are abundant. Various ' forms ' have been described, but no attempt has been made to divide the species into geographical races or subspecies, though there is an obvious difference between the females of the southern group and those of the northern and western areas ; the males however exhibit no great difference in pattern or colour. REVISIONAL NOTES ON AFRICAN CHARAXES 207 In 1904, Suffert described the form (subsp.) fasciatus, based on males and females from the Mhonda area of the Morogoro district of Tanzania. In 1925, Joicey & Talbot described a female from the southern Sudan as f. monticola. Poulton (1926) refers to these two ' forms ' as ' Abs '. Up to this time, the species was represented in most collections mainly by male specimens, this sex being much in evidence throughout its range. Since the introduction of the ' hanging trap ' method of capture, large numbers of females have been taken, and these indicate clearly that the species can be divided up into two main groups, achaemenes of the southern areas and those of the northern zone, north of the Equator. The first reference in literature to a recognition of a northern subspecies is that of Carpenter & Jackson, 1950, when they refer to examples of the species from the Suk area of Kenya, trinominally, as achaemenes monticola Joicey & Talbot. This is a reference in the text, but there is no formal elevation of the name monticola to sub- specific rank. Having examined a large quantity of material from throughout the range of the species, the following division is submitted. It is supported by ecological factors.

Hind wing basal area rufous, merging into proximal edge of discal bar in cell area and into the more greyish of the inner fold ; the upper end of the bar slightly paler than fore wing bar ; distal portion of wing black with a well marked series of white lunules edged with bluish opposite the tails in submarginal zone ; marginal border slightly orange toward upper angle, more strongly blue opposite tails, then olive at anal angle. Tails thin and long, upper 8-9 mm, lower 10 mm. Underside. Much as in the male, pattern slightly bolder ; the disco-postdiscal and discal bars in hind wing creamy white. Variation. The males are remarkably constant ; a few may show a slight increase in size of the submarginal spots in the hind wing. Females also hardly vary ; there may be an increase in the degree of blue around the submarginal spots in the hind wing, this colour sometimes tending to encircle the spots of the lower end opposite the tails ; these slight variations seem to occur more often in the low coastal areas of Mozambique. Occasional aberrations exhibiting partial melanism have been recorded. Overlaet figures a gynandromorph from Upemba Park, Katanga. Range : The type is said to have come from Port Natal (Durban), but probably came from further inland. The species occurs commonly in Transvaal, S. Mozam- bique, Rhodesia, Zambia, eastern Angola and Katanga ; western and central Tanzania ; also in the savannah country of Kenya around Taveta, Voi and Kibwezi. In south-eastern and eastern Tanzania the ' form ' fasciatus Suffert occurs, and is dealt with separately hereafter.

C. achaemenes of the northern regions, north of the Equator, from north of Lake Victoria to Ethiopia and Sudan represents an ecological aggregate sufficiently distinct from nominate southern achaemenes, deserving of recognition, as a good subspecies. Representatives of this aggregate in the more western areas of the Central African Republic, N. Cameroons and N.E. Nigeria differ slightly and are referred to separately. Males of monticola are very stable, but females are rather variable within the restrictions which separate them from nominate achaemenes. MALE. Fore wing length 35-36 mm ; shape usually rather falcate. Upperside. Fore wing pattern as in the nominate race, the junction of the olive base with the black beyond, more strongly greenish ; the disco-postdiscal bar rather narrow as a rule, seldom exceeding 5 mm in ib. The marginal spots very small. On the hind wing the submarginal spots are usually small with little or no blue distally. Upper tails short, 4-5 mm, lower 8 mm. Underside. Pattern as in nominate race, but distal portions of both wings more brownish ; the postdiscal lunules stronger. FEMALE. Fore wing length 41-45 mm ; shape less falcate than in the male. Upperside. Fore wing pattern generally similar to that of the nominate race but spots rather more restricted, the marginal spots smaller. Three forms occur : Form i. The ground colour is very similar to that of the male ; the fore wing disco-postdiscal bar creamy white except for the spots in the postdiscal line, which are slightly tinged ochreous ; the marginal spots small and ochreous. Hind wing black band broad, the submarginal spots moderately large. This form is thus somewhat ' male-like ', and is exceptional. Wing length 41 mm. Form 2. Ground colour of fore wing as in form i, but disco-postdiscal spots orange-ochre except for lower ones in ib & la, which are creamy white. Marginal spots small, ochre-orange. This is the dominant form and agrees with the type. (PI. 2, fig. 19.) Form 3. The base of the fore wing rufous chestnut ; the spot at end of cell more distinct ; the disco-postdiscal bar more orange-ochre to hind margin ; the marginal spots larger. The bar on the hind wing ochreous ; the submarginal spots larger. Undersides in all three forms much as in the male, but pattern bolder. (PI. 2, fig. 18.)

It was described as being ' a little smaller than the nominate form. Dorsal pubescence of the thorax the same colour as the adjoining parts of the wings ; otherwise colour and pattern of body as in typical form'. There REVISIONAL NOTES ON AFRICAN CHARAXES 211 is nothing in the detailed description which follows to distinguish it from males from further south in S. Sudan, i.e. monticola. Storace compared it with males from S. Congo (Katanga). Butler records achaemenes from Atbara and Karidera on the Nile in northern Sudan, and Wilson (1950) notes the species as common in ' Central Sudan ' around Khartoum. The female has not been recorded so far as I know. The status of this taxon requires re-investigation. Charaxes achaemenes cline monticola x atlantica (Map 3) Specimens from the northern Cameroons were originally associated with monticola but examination of material from the Central African Republic west to northern Cameroons and eastern Nigeria suggests that this aggregate really represents a cline between typical monticola and the more western race of Senegal, Gambia etc. MALE. Fore wing length 40 mm. Upper side. Coloration and pattern similar to monticola. Underside. Ground colour paler throughout, but pattern similar. FEMALE. Variable. Form i. Very similar to Form 2 of monticola. Upperside. The disco- postdiscal bar similar in colour but rather broader throughout, orange-ochre to 2, then creamy to hind margin. Underside. Very similar to monticola but paler. Form 2. Upperside. Somewhat similar to Form 3 of monticola but fore wing disco-post- discal bar broader and rich rufous orange ; the marginal spots larger. On the hind wing the basal area more rufous, the black band less wide, the submarginal spots bolder, those in the lower half with strong blue distally. Marginal border orange at upper half, then white with strong blue scaling to anal angle. Underside. As in Form i. Mr R. G. T. St Leger suggests that the forms are ' climatic ', Form i being found in the Enugu area and the rufous orange form further north-west near the border between east and north Nigeria, but in the Cameroons they occur together.

REVISIONAL NOTES ON AFRICAN CHARAXES 213 The upperside of the male bears a superficial resemblance to Charaxes druceanus, but the underside is totally different. MALE. Fore wing length 41—44 mm. Upperside. Fore wing, ground colour of basal area rufous tawny ; discal band more orange ; distal border of wing black ; there is a short black narrow bar in subcostal area before the end of the cell, followed by larger black bars, basal in 4, 5, 6 ; then an irregular black bar beyond on inner border of discal orange band in 6-5 followed by a larger mark in 4 and larger rounded marks in 3-2 with a smaller spot in ib ; a triangular black subcostal mark, apex down, separates the ' fork ' of the rufous orange band at its costal end and is represented in 5-2 by smaller spots indicating the line of fusion between the discal and postdiscal series ; width of band at hind margin 10 mm. Margin of wing with strong orange spots, double in ib. Hind wing, basal area slightly duller rufous, shading to dull rusty on the inner fold ; discal band, more orange, 10 mm wide at costa, is uniform in width to cell area, then tapers toward the inner fold above the anal angle. It is ill-defined on inner edge, clearly defined on outer margin where it is bordered by a black band, tapering at both ends but is rounded at the anal lobe which carries one elongate or two mauve spots. Margin with strong tawny orange lunules separated only by black veins ; edge black with slight white fringe within the bluntly dentate margin ; tails short, robust, sharply pointed, at 2 & 4, 4-5 mm long. Underside. Fore wing, basal area rufescent chestnut, more olive-russet on outer border. Discal band rusty ochre, paler at hind end, the ' forked ' upper portions accentuated by black lines with buff surround ; the subcostal bars narrowly black with silvery white outlines, the bars in sub-bases of ib-3 more strongly black, outlined whitish. The postdiscal series of black spots, narrowly edged bluish grey distally, complete, the spots increasing in size from apex to the double mark at the tornus ; edge of wing slightly orange with a series of black marks at ends of veins, interrupted by whitish ochre in between. Hind wing, ground colour in basal triangle rufescent chestnut to discal line where the band is hardly indicated, but is crossed by transverse buff lines along the veins, offset proximally by a series of short black lines strongly edged with white distally and extending to the inner fold above the anal angle ; the basal area crossed by three white-edged fine black lines ; the three lines on the inner fold above the anal angle more or less parallel. The border of the wing more orange-olive ; edge black with white fringe. FEMALE. Larger than the male, fore wing length 46-48 mm, with a straighter outer border than the male. Upperside. Fore wing, basal area as in the male, the black marks similarly placed, but discal band paler creamy yellow from hind margin to 2-3 proximally, shading to orange-rufous distally, the ' fork ' of the band rufous orange with paler centres ; border black with large rufous orange marks on margin. Hind wing, extreme basal triangle rufous tawny, shading to greyish ochre on inner fold ; discal band yellowish creamy, not sharply defined on inner border and distally shading to tawny orange at the broad black border, which carries a black ocellus with lilac spots at the anal angle. Margin with conspicuous orange lunules ; edge black, slightly dentate ; tails on 2 & 4 black, upper 6 mm, lower 4-5 mm. Underside. Ground colour as in the male but duller, though bars and spots are strong ; discal band buff- white and clear-cut and extending through the inner fold ; the postdiscal and submarginal alternate black and whitish marks on a duller more olive ground are well represented, the white marks of the two rows connected by white streaks. Margin as in the male. The female thus bears a resemblance to that of Ch. druceanus teita on the upper side. This species was reared in some numbers by the late Malcolm Berkeley, from eggs and larvae found on Bersama abyssinicus (Melianthaceae) in the Adola district of southern Ethiopia. Range : This species is somewhat restricted, being confined to the north-west, west and southern districts of Ethiopia. It is recorded from Shoa : Mahal-Uong, Axelena, Feleklek and Scioatalit, where it was originally discovered by Antinori in 214 V. G. L. VAN SOMEREN 1865 ; it also occurs at Youbdo in south-west Ethiopia where it was common (Ungemach) and was plentiful at Adola in southern Ethiopia. Charaxes brutus Cramer The species Charaxes bmtus ranges through a large part of Africa, from Ethiopia to the Atlantic coast of Senegal and Sierra Leone, then south to Angola. On the eastern side, it extends to the Natal area of South Africa. It has evolved into several distinct subspecies, but where two of these converge and tend to overlap, there is evidence of intergradation ; thus brutus brutus intergrades with brutus angustus in the mid Nigerian area, and angustiis intergrades to an even greater extent with alcyone in the eastern Rift Valley ; and alcyone with natalensis in Tanzania. There is evidence to suggest that junius meets somalicus in the south- west of Ethiopia. It is a forest, woodland and heavy savanna species, and since suitable habitats exist in almost continuous sequence throughout its range, clear- cut ecological barriers hardly exist. The species has extended to some of the islands in the Gulf of Guinea, and also to the islands off the east coast. The insular race antiquus Joicey & Talbot of Sao Thom6 clearly exhibits relation- ship to mainland bruttis, but that of Fernando Po has not diverged from the mainland race. On the other hand, the insect found in Madagascar, andara Ward, has a very distinctive female which has resulted from complete separation over millions of years. It should, in my opinion, be considered a distinct species. The fact that the genitalia of andara is very similar to that of brutus is of little significance, for many well-defined species of Charaxes have almost identical genitalia. Rothschild (1900) recognized five subspecies and since that date one more insular race has been added ; several forms have been described. I propose to deal with each in geographical sequence. Charaxes brutus brutus Cramer (PI. 3, figs 25-26, Map 4) Papilio eques Achivus brutus Cramer, 1779 : 82, pi. 241. Locality : Cape d. g. Hoffn. [Patria falsa.]. Papilio Eques Achivus cajus Jablonsky & Herbst, 1790 : 65. Locality : Cap. d. g. Hoffn. [Patria falsa.]. For full synonomy vide Rothschild, 1900 : 423. Corrected type-locality : Guinea-Sierra Leone. This is a black species with white bands crossing both wings, the hind portion of the fore wing band coinciding with the costal portion of the hind wing band. MALE. Fore wing length 42-44 mm. Upperside. Fore wing, ground colour black, with slight greeny sheen toward base. Disc of wing crossed by a white or slightly yellowish creamy band, widest at the hind margin at la-ib, 8-9 mm wide and contiguous ; spots from 2-7 of decreasing size and well separated so that the band appears broken and tapers toward the costa. Margin with small internervular white dots or lines, distinct or vestigial. Hind wing, ground colour as fore, slightly more greyish toward inner fold, which shades to rufous along the inner REVISIONAL NOTES ON AFRICAN CHARAXES 2i6 V. G. L. VAN SOMEREN edge and above the anal angle. Disc of wing crossed by a white band, widest at costa, the band almost parallel-sided, then tapering at inner fold to above the anal angle. Average width of band 8-10 mm, usually bordered by bluish scaling. Tornus or anal lobe with two bluish dots and sometimes one in space above. Margin of wing serrate, with sharply pointed tails at veins 2 and 4, of about equal length, 5 mm. Underside. Fore wing, ground colour at bases of wing chestnut, shading to greyish at bases of la-ib in fore wing. Basal half of costal vein white. Subcostal area, including the cell, crossed by irregular shaped black bars boldly outlined in silvery white ; two similar marks in ib and 2 and one sub-basal in 3 ; the outer spots accen- tuating the graduated white bar on its inner border. Ground colour on distal portion of wing olive-brown, with a continuous series of somewhat triangular black marks narrowly outlined distally in white in the postdiscal line ; the black marks at tornus with more conspicuous bluish white margins ; margin with black marks at end of veins, with white fringe in between. Hind wing ornamented with angular black marks, long ovoid in subcostal area, more elongate to linear toward inner fold, all marks boldly outlined in silvery white ; a series of black marks boldly accentuating the proximal edge of the white discal bar. Ground colour of distal portion of wing olive-brown, crossed by an intricate pattern of two rows of black marks connected by silvery blue criss-cross lines on a chestnut ground ; spot at anal angle more solidly black, with two bluish white central dots ; margin with strong black lunules narrowly bluish internally. FEMALE. Very similar to the male but generally larger ; fore wing length 45-47 mm. Upperside. Fore wing, ground colour black as in the male but slightly more brownish toward the base of the wing. Hind wing, as in the male. Discal bars white or slightly creamy yellow- ish, in general form conforming to that of the male, but bolder, the hind wing bar extending into the inner fold above the anal angle. In this sex also, the fore and hind wing bars are of about equal width at the point of overlap, so that the bands appear continuous and unbroken. (Cf. angustus, in this respect.) Border of wing black to edge ; margin serrate ; tails longer than in the male, the upper one usually the longer. Range : The nominate race is distributed from Guinea-Sierra Leone, Liberia and Ivory Coast to western Nigeria. There appears to be some intergrading with the next race in N.E. Nigeria. Charaxes brutus angustus Rothschild (PI. 3, figs 27-30, Map 4) Charaxes brutus angustus Rothschild, 1900 : 432. Rothschild compared this race with the southern natalensis Staudinger which is confusing, and not with nominate brutus, which it more closely resembles. The conspicuous difference on the upper side is the narrowness of the fore and hind wing discal bars which do not coincide at the point of overlap, that of the upper wing being offset. MALE. Fore wing length 43-46 mm. Upperside. Fore wing, ground colour black, with slight greenish sheen over basal area. Discal bar white or slightly tinged yellowish cream, extending from the hind margin to subcosta, arranged as in the nominate race, but differing markedly in the width of the marks in ia-ib-2 which are reduced to 3-4mm wide on the proximal side, so that at the point of overlap with the band of the hind wing is offset distally to the band of the fore wing. Margin with very slight trace of whitish spots, or immaculate ; margin slightly incurved above 3. Hind wing band white, widest at costa, 5-6 mm, tapering toward the inner fold above the anal angle, but not crossing it ; the band almost straight on inner border but slightly curved on outer. Basal area greenish black shading to brownish on inner fold. Anal lobe with two blue dots, a blue spot in area above, and a trace of one beyond, REVISIONAL NOTES ON AFRICAN CHARAXES 217 opposite upper tail ; margin with narrow white interspaces present or absent. Margin serrate ; tails 4 mm long, of equal length, or lower one slightly shorter. Underside. Colour and pattern as in nominate race but slightly paler, the white bars narrower. FEMALE. Fore wing length 46-52 mm, thus larger than the male ; the outer margin only slightly incurved. Upperside. Fore wing, ground colour as in the male, but basal areas more greenish brown ; bands of wings similar in shape but bolder, bar of hind wing extending through the inner fold above anal angle. Two blue spots in anal lobe larger ; margin serrate and tails well formed as in the male. Underside. As in the male, but ground colour slightly paler and the submarginal black marks and those in the postdiscal row showing up more clearly. Specimens from the island of Fernando Po are similar in pattern and colour to those of the mainland ; they may be slightly larger, but not always so. Variations : Two aberrations have been described and named, viz. — fractifascia Le Cerf, 1923 : 365. Gabon ; nigrescens Le Moult, 1933 : 17, T. 4, fig. 9. Etoumbe, Moyen Congo. Two aberrations taken by Mr T. H. E. Jackson's African collector in the Moyen Congo are figured (PL 3, figs 29-30). Fig. 29 depicts a male with the fore wing bar almost completely obliterated by black scaling, and barely indicated. The hind wing however is normal. On the underside the usual chestnut ground colour of the basal area is replaced by creamy white ; the margin border is greyish, so that the postdiscal series of black triangular spots are conspicuous. The hind wing is however more or less normal though the chestnut ground colour is paler. Locality : French Equatorial Africa, Kata Forest, Ouesso, vii-59. Fig. 30 depicts a male with the usual white bars of the fore and hind wings reduced to a series of dyslegnic spots, those of the fore wing not reaching the subcosta, and only slightly indicated in la. The underside exhibits a strong development of melanism in the basal 2/3rd of the fore wing up to the discal line which is reduced in width. On the hind wing the normal chestnut ground colour is replaced by white, but with heavy black streaks in the subcostal region and with a large black mark at the base of the cell. Locality : French Equatorial Africa, Kata Forest, Ouesso, viii. 59. Range : The subspecies angustus ranges from northern Angola, Kasai and Katanga, central Congo and the Kivu region to the Semliki Valley and western Uganda in an eastward direction ; on the western side it extends from Moyen Congo, Gabon, Central African Republic and Cameroon to eastern Nigeria. It also occurs on the island of Fernando Po. We must now consider an aggregate occurring in the southern Sudan, the northern and eastern areas of Uganda and in N.W. Kenya. These specimens have usually been referred to in literature as brutus brutus Cramer. (Vide Rothschild, 1900 ; Carpenter, 1928 ; van Someren, 1928 ; Stoneham, 1964.) However, this aggregate is separated from nominate brutus by brutus angustus. (Vide distribution ante, and Map 4.) They are variable, some exhibiting the characters of angustus, i.e. the narrow fore wing bars in areas la-ib, and the comparatively narrow hind wing bar ; others have an expansion of the fore wing bar on the hind margin, and a widening of the bar in the costal region of the hind wing. In my view, they represent a transitional aggregate between brutus angustus and brutus alcyone Stoneham, and are unstable. (Vide note on brutus alcyone, post.) Charaxes brutus junius Oberthur 1883 (PI. 3, fig. 31. PI. 4, fig. 32, Map 4) Charaxes brutus vox. junius Oberthiir, 1880 : 166. 2i8 V. G. L. VAN SOMEREN Charaxes junius Oberthiir, 1883 : 728. Char axes junius f. ragazzi Storace, 1948 : 132. Characterized by the very narrow creamy yellowish white bars of fore and hind wings and strong marginal spots on both fore and hind wings. MALE. Fore wing length 42-44 mm. Upperside. Fore wing, ground colour black, with slight olive-brown at base of fore wing, more brownish on hind wing, shading to greyish brown on inner fold. Fore wing with comparatively narrow yellowish cream bar crossing the wing from about mid hind margin to subcosta ; widest at hind margin, 6 mm, the spots gradually decreasing in size ; the marks in la-ib separated by black vein ; the general arrangement of the spots similar to that of angustus. Margin of wing with conspicuous ochreous spots between veins. Hind wing, bar very slightly wider than that of fore at costa, of even width to 4, then narrowing slightly toward inner fold and crossing this above anal angle. Anal lobe with two blue dots. Margin of wing only slightly serrate, more dentate. Tails robust and sharply pointed, 5-4 mm long. Underside. The basic pattern similar to that of other brutus ssp., but the ground colour is less deep chestnut and the distal portion of the fore wing more brownish, less olive ; the bars are less strongly black-centred ; the postdiscal black spots less intense black except toward the hind angle. The discal band is creamy ; margin of wing distinctly ochreous, broken by intermediate black spots. On the hind wing the basal bars are mainly chestnut, thinly outlined in silvery white ; the discal bar creamy, while the postdiscal black is limited, the upper marks are more arrow-shaped, but the two toward the anal angle are distinct black rings with bluish ocelli. The marginal border is strongly ochreous, black edged with white internervular fringe. FEMALE. Very similar to the male but much larger, fore wing length 46-48 mm. Upperside. Ground colour rather browner than male especially at base of wings and along the inner fold of the hind wing. Creamy discal bands on fore and hind wing broader throughout ; marginal spots on fore wing distinct. Hind wing ochreous lunules well marked. Underside. As in the male, but pattern bolder. I have not been able to examine the form ragazzi Storace. Range : This race is apparently limited to the Shoa districts of western Ethiopia, and is recorded from Sciotalit and Feleklek (Antinori). Charaxes brutus somalicus Rothschild (PI. 4, fig. 33, Map 4) Charaxes brutus somalicus Rothschild, 1900 : 432. Characterized by the very narrow discal bars of both wings which are yellowish cream to ochre. Spots on margin of both wings small. MALE. Fore wing length 40-43 mm. Upperside. Fore wing, ground colour black with slight purplish brown sheen on bases of wings, more greyish on inner fold. The fore wing band yellow-creamy white, very narrow throughout, the spots in za-ib not more than 3-4 mm wide ; the remaining spots gradually reduced in size as the band tapers toward the costa. Marginal spots small but clear. Hind wing, the band is widest at costa, 4 mm, then tapers to 2 mm at inner fold where it is slightly ochreous ; the mark at the costa set in so that the hind wing band is ' stepped ' and not in line with the hind marginal spot of the fore wing. The margin carries dark ochreous lunules, sometimes obscured ; two blue spots present in the anal angle ; margin of wing slightly dentate. Tails short, robust, 3-4 mm long. Underside. Fore wing, ground colour deep chestnut-brown at basal 2/3rds, the distal portion of the wing brownish olive ; the bars and spots of the fore wing greyish rather than black, with narrow black and white REVISIONAL NOTES ON AFRICAN CHARAXES 219 edges. The discal band creamy ; the postdiscal triangular black spots narrowly edged greyish, those at the tornus with more greyish distally ; margin with ochreous spots, slightly blackish in between. Hind wing basal bars and lines chestnut finely outlined in white ; discal creamy bars strong and clear-cut. Distal portion of wing paler chestnut ; the postdiscal series of black spots distinct, narrowly edged greyish distally ; the black spot with double purplish blue dots in anal angle ringed with deep ochreous which is continued up the margin ; edge black. FEMALE. I have not been able to examine this sex, and can find no description. Range : Found mainly in the southern districts of Ethiopia, ranging from the Harar highlands in the east to Adola in the south, then crossing the Rift to Youbdo in the west. Carpenter reports some evidence of transition toward ' bmtus ' [sic] in the Didinga Mts region, but this needs clarification. Charaxes brutus alcyone Stoneham (PI. 4, figs 34-35, Map 4) Charaxes brutus alcyone Stoneham, 1943 : 3. Charaxes brutus natalensis van Someren & Rogers, 1928 [nee Staudinger & Schatz, 1886]. Very similar to natalensis Staudinger & Schatz, with which it has hitherto been associated. It is of interest to note that when Rothschild wrote his Charaxes Monograph in 1900, he records the statement, under the heading brutus natalensis, ' not yet recorded from the coast districts of British East Africa.' He, however, records this race from Kilimanjaro and the coastal belt of German East Africa (now Tanzania). Specimens from Nandi, N.W. Kenya, are stated to agree better with nominate brutus than with angustus. I have already pointed out that these insects are not typical brutus but are a mixed aggregate. We now know that a race of brutus does extend all along the Kenya coast and inland to the Kikuyu country east of the Rift Valley and that west of the Rift we find a mixed aggregate or cline, largely tending toward angustus. The coastal insect has received the name alcyone Stoneham, and though the characters of the race are not outstandingly different from those of natalensis, they are sufficient to warrant recognition. MALE. Fore wing length 40 mm (average). Upper side. Differs from natalensis mainly in the formation of the creamy white bar of the fore wing, which is straighter on the distal border, less strongly curved, the three upper spots being in line ; the mark in area 2 is larger, thus the band does not taper so rapidly from this point to the costa. The marginal white spots usually larger and more distinct. The white band on the hind wing slightly wider, being extended basad ; the margin with more conspicuous white triangles or lunules. FEMALE. The same characters as those of the male are present, to a greater degree, in the female, the hind wing band being very wide and expanded proximad. Underside. Very similar to that of natalensis, the white bands stronger generally, while the distal portion of the fore wing ground colour is paler, the angular marks less extended. Range : The coastal belt of Kenya and hinterland, extending inland to the eastern side of the Rift Valley ; also in the adjacent coast of Tanzania. 220 V. G. L. VAN SOMEREN Charaxes brutus natalensis Staudinger & Schatz (PI. 4, figs 36-37. Map 4) Charaxes brutus var. natalensis Staudinger & Schatz, 1886 : 169. Charaxes brutus var. Butler, 1865 : 625. MALE. Fore wing length 40-41 mm. FEMALE. Fore wing length 45 mm. Upperside. This race is characterized in both sexes by the white fore wing bar, which tapers from the hind margin to 2, then more rapidly up to subcosta. Margin with small ochreous spots on veins in fore wing and some indication of white dashes in the serrations of the hind wing. Hind wing white bar with bluish borders wider than in brutus brutus. Underside. Ground colour slightly paler chestnut in basal areas but black, white-outlined marks strongly developed ; white bars strong ; submarginal triangular marks well developed in fore wing ; those of the hind wing more in the form of irregular ocelli ; marginal border broad, edge black ; margin of hind wing strongly serrate. Range : From the Natal district of South Africa, northward through Rhodesia, Zambia, Malawi and northern Mozambique to Tanzania. Biological note. The early stages of most of the races have been recorded. Numerous food plants are recorded and these include : Euphorbiaceae, Fluggea microcarpa ; Tiliaceae, Grewia forbesi & Grewia sp. ; Melanthaceae, Bersama sp. ; Meliaceae, Turraea sp., Ekebergia reupelliana, Melia volkensii, Melia azarach ; Sapindaceae, Philodiscus zambesiacus. The great variety of food plants accounts for the wide distribution of the species. It is of interest to note that although eggs are freely laid on Melia azarach (Tiliaceae) (an exotic, often called Cape or Persian Lilac), the larvae when hatched, refuse to feed and die ; they can however be raised on this plant in captivity. On three occasions I have found a female brutus ' in cop ' with a male candiope in a ' charaxes trap '! One such female was caged and she laid a batch of eggs which all produced normal brutusl Charaxes brutus antiquus Joicey & Talbot (PI. 4, figs 38-39* MaP 4) Charaxes brutus antiquus Joicey & Talbot, 1926 : 1-5. Characterized by the thick tails in both sexes and the presence of a series of pale lunules along the admargin of the hind wing. MALE. Fore wing length 42 mm. Upperside. Ground colour black with a slight greeny sheen at base of fore wing, more greenish on hind wing ; the inner fold of the hind wing more greyish. Fore wing, creamy white bar widest at the hind margin, 6 mm in la, the inner end of the mark oblique, the remaining marks decreasing in size rather rapidly toward the costa ; margin of wing with small white spots. Hind wing, discal bar extending from the costa, where it is 7 mm wide, and slightly inset to the mark on the fore wing in la ; the bar is of about equal width or slightly expanded over the cell area, then tapers to the inner fold above the anal angle ; the bar is slightly greenish on its borders. Admargin of wing with whitish lunules which are rather obscured in the region of the tails ; margin black and slightly dentate, but tails are thick and robust, upper 6 mm, lower 5 mm and more pointed ; anal lobe with double bluish dots. Underside. Fore wing, ground colour chestnut at base, rather more ferruginous on distal REVISIONAL NOTES ON AFRICAN CHARAXES 221 portion of wing. Bars and spots in basal area black with strong white edging, the spots border- ing the white discal band stronger black. Postdiscal triangular black marks lightly bordered with greyish white, the marks at the tornus strong ; margin with alternating black and white spots. Hind wing, basal area chestnut ground colour with silvery white marks enclosing chest- nut, but smaller spots adjoining the discal bar, blacker. Discal bar silvery white with irregular outer border offset by a zigzag line of strong chestnut turning to black above the anal angle. Postdiscal row of chestnut triangles, edged greyish internally, is offset by a row of black lunules which form ocelli at the anal angle. Admargin with a more orangy line, edges whitish distally, and accentuated by the black margin. Tails black. FEMALE. Fore wing length 50 mm. Upperside. Pattern of wing generally similar to that of the male but ground colour rather more brownish black. Fore wing creamy bar similar to that of male but bolder, the mark on hind margin la n mm wide. Margin with rather obscure white internervular spots, more distinct toward the apex of the wing. Hind wing basal area brownish black with slight olive tinge, shading to greyish on the inner fold. Discal band broad, 10 mm at costa, creamy white, with irregular outer border in mid area, tapers toward the inner fold but does not cross it. Admarginal pale lunules somewhat obscured ; edge black, with a very narrow white fringe. Tails thick and robust, upper 10 mm long. Underside. Generally similar to that of the male ; fore and hind wing bands silvery white and strong. Range : Known only from the island of Sao Tome in the Gulf of Guinea. Charaxes andara Ward (PI. 5, figs 40-42, Map 4) Charaxes andara Ward, 1873 : 209. I referred to this insect, very briefly, in the introductory remarks, where I gave my opinion that andara should rank as a species, distinct from bmtus, and stated my reasons. The sexes are dissimilar, thus differing markedly from any mainland race of brutus. That andara may have been derived, many millions of years ago, from a common ancestor with brutus is not denied, but one must realize that Madagas- car now has several endemic species peculiar to the island. The relationship, if any, of andara to brutus might be clarified by inter-breeding. MALE. Fore wing length 40-42 mm. Upperside. Fore wing, ground colour black with a strong greenish sheen over the cell and base, blacker on distal portion. Margin bluntly dentate, with a distinct projection at upper part of ib, the dentate appearance enhanced by the strong ochreous white internervular spots ; the wing appears strongly incised in area 2. Discal white band, strongly bluish on borders at la-ib where the marks are 7-8 mm wide and conjoined, tapers to 2-3 where the marks are free ; the spot in 4 is much smaller and linear, that in 5 set out, followed by two smaller spots in 6-7, so that the bar is strongly ' kinked ' at 4-5. Hind wing, basal area black with slight greenish sheen, becoming greyish on the inner fold which is edged with rufous. Discal white band, which is 5-7 mm wide at costa, bulges inward over the cell area ; the outer border is here slightly curved and strongly edged with blue, but on the inner border the band tapers toward the inner fold, but stops short at this point. The outer border of the wing is blacker, with a bluish sheen ; the margin strongly serrate ; each serration with a white V at base ; anal lobe greenish on edge, carrying two lilac spots ; the tails long, thin and sharply pointed, 7 mm. Underside. Fore wing, basal ground colour light chestnut, the distal portion of the wing more orange-olive. The subcostal marks are very strongly edged with satiny white, the marks at bases of cellules blacker, with narrower white edging. The discal white bar strong but irregular in outline, especially on the outer border at 2-4. The postdiscal series of black marks rather rounded, outlined in bluish grey, particularly on the Outer aspect, thus forming ocelli, the black marks more angled at the tornus ; margin with 222 V. G. L VAN SOMEREN black at end of veins with white in between. Hind wing, basal area lighter chestnut, the basal marks and longitudinal lines narrowly black-centred with white borders ; the discal satiny white bar, narrower than above, narrowly crosses the inner fold at an angle and is flanked proximally by black linear marks, and distally by a darker chestnut zone carrying a zigzag olive line. The submarginal row of linear marks shaded with lilac-grey proximally, terminates at the anal angle in a chestnut ocellus bearing lilac dots ; margin orange-olive, more olive at anal lobe ; edge black. FEMALE. Usually larger than the male, but occasionally as small ; fore wing length 42- 47 mm. Upperside. Fore wing, differs from the usual brutus female in that the bar is expanded from 4-7 and consists of conjoined discal and postdiscal marks, the mark in 4 extending toward the end of the cell ; moreover, the bar is largely rufous orange in colour. Ground colour in basal area deep brownish black with slight greeny sheen ; the discal area blacker with distinct orange spots on the margin, though small at tornus below the projection at upper part of ib. Margin of wing less incurved than in the male. The discal bar is unusually wide, white in areas za-ib, slightly orange distally, width at hind margin 12 mm in large specimens, usually 10 mm in average females, the mark in 2 quadrate and orange, that in 3 smaller and quadrate or angled distally, followed by a long linear orange mark basal in 4, the long orange mark in 5 set out ; above this the bar divides into two, discal and postdiscal, two marks each in 6—7, though those in 6 may be slightly conjoined. Hind wing, basal area more greyish with slight greenish bloom turning grey on inner fold and slightly rufous on margin. The discal bar white, edged with bluish particularly on outer border, 7-8 mm wide at costa expanding over the cell area to 10-12 mm, then tapering towards but not crossing the inner fold. Border of wing deep brownish black ; anal lobe with two bluish green dots. Margin with conspicuous orange lunules shaded greenish at anal lobe ; margin strongly serrate ; tails long and thin, sharply pointed, 10 mm, with a definite tail at 3 in between, 6 mm long. Underside. Pattern as in the male but bolder, the basal chestnut paler but the orange border wider. There is some superficial resemblance on the upperside between these females and those of Charaxes cacuthis ; both are limited to Madagascar. Range : Limited to Madagascar, the species is generally distributed on the island but the majority of specimens come from the eastern side. Variation in size has been noted. The species has been bred in numbers but unfortunately no record kept of the foodplant. SYSTEMATIC LIST Charaxes phoebus Butler Charaxes phoebus Butler, 1765. Type locality : ' Abyssinia '.

CHARAXES BOUETI FEISTHAMEL and CHARAXES LASTI GROSE SMITH Charaxes boueti Feisthamel References to this species in literature present a rather confused picture, due mainly to the following factors, the paucity of nominotypical material, the vari- ability of the species and the association with it of a rather similar though distinct species, Ch. lasti Grose Smith. The picture is further complicated by the curious discontinuity of distribution, which is difficult to explain. The species can be divided into two groups, on evidence of pattern, as detailed below ; GROUP i. boueti boueti, boueti ghanaensis, and boueti macdounii ; GROUP 2. boueti rectans and boueti alticola. 224 v- G. L. VAN SOMEREN Originally described from Casamanca, Senegambia, in 1850, this species is still badly represented in collections ; the few examples of the nominate race all come from the extreme west : Senegal, Portuguese Guinea and Sierra Leone. It has not been recorded from Liberia (Fox, 1965), nor from the Ivory Coast in spite of extensive collecting. A distinct race is recorded from the borders of Togo and Ghana. The species is not recorded from Nigeria, Cameroons nor the northern area of the Central African Republic. This is difficult to explain, since suitable habitats containing the known food-plant Oxytenanthera (Solid Bamboo), Gramineae, occur throughout the savannah belt which extends from western Abyssinia to Senegal ; (Zones 16 & 17, UNESCO Vegetational Map, 1959). Even more remarkable is the fact that in the eastern extremity of these zones, a representative of Group 2, viz., boueti redans, occurs. Equally strange is the fact that the third representative of Group i, viz., boueti macclounii occurs in the areas of south Katanga, Zambia, Malawi, S. Tanzania and Rhodesia, and this is separated from western representatives by the whole of the vast low tropical forest of the Congo. The food plants are Oxytenanthera abyssinica and 0. brounii. The second member of Group 2, viz., boueti alticola, is limited to the high Bamboo zones of the Kivu-Kigezi countries, where it feeds on the Alpine Bamboo, Arun- dinaria alpinus, a hollow species. Variability of the species takes two forms : a) a pale, lightly marked form ; b) a dark, heavily marked one. Moreover, the undersides may be lightly or heavily marked in the two forms. This variation is not seasonal as they can be taken at one and the same time. Talbot (1927) expressed the view that alticola Griinberg was a distinct species, basing this opinion on the evidence of the very strong pattern and rather distinctive white area in the hind wings of the males. He suggested that alticola was mimetic of Char axes ansorgei ruandana. Though the two may occur in the same general area, their habitats are different and do not coincide ; alticola is restricted to bamboo zones and ansorgei to forest, and where the two habitats may be contiguous, alticola outnumbers ansorgei in the ratio 100-1. This was my experience at the Kanaba Gap, in Kigezi, where I spent three weeks in 1950 and again in 1952. Talbot failed to note that in female boueti rectans there is a pattern transitional between that of alticola and macclounii, but tending more to the former, as is to be expected. GROUP i. Charaxes boueti boueti Feisthamel (PI. 5, figs 43-48, Map 5) Charaxes boueti Feisthamel, 1850 : 261. There are two forms, one with strongly marked pattern on an orange ground, the other lightly marked on a paler ground. MALE. Fore wing length 34-36 mm. Upperside. Fore wing, ground colour rufous orange, slightly darker at basal triangle, border black with conspicuous orange spots on outer edge, increasing in size from apex to ib. Median black spots arranged as follows : an inverted REVISIONAL NOTES ON AFRICAN CHARAXES 225 226 V. G. L. VAN SOMEREN ' comma ' mark beyond end of cell, a linear mark crosses the sub-bases of 5-6, followed by crescentic marks of diminishing size sub-basal in 3-ib, and a larger black mark crosses the sub- bases of 7 & 6. The upper part of the disco-postdiscal orange bars are separated by a broader series of black spots crossing 7-6 & 5-4 in a curve and slightly in 3. Hind wing, ground colour rufous orange in the base, followed by a brighter orange discal band, slightly paler at the costa and tapering to above the anal angle ; inner fold paler with some long greyish hair-like scales along ic.

Fore wing length 36-38 mm. Upperside. Fore wing, general ground colour richer rufous orange than nominate race, more closely approaching ghanaensis, but rather variable. Basal areas darker than disco-postdiscal bands ; black spots in median line stronger and extending to ib ; intermediate black spots between discal and postdiscal orange spots in upper half larger and more defined and extending to 2, and often to ib, thus separating the two rows ; 228 V. G. L. VAN SOMEREN the upper postdiscal spots in 7-5 in a curve as in the nominate race and ghanaensis ; marginal rufous orange present but not so defined. Hind wing, basal area often darker ; the discal rufous orange, paler at costa, in discal line strongly offset by the black submarginal band, which is widest at upper half then tapering toward anal angle and often separated into spots, cul- minating in the greenish anal angle with its lilac and black spots. Orange border thus wider but black edge less strong. Tails short, upper 2—3 mm, lower 4-5 mm. The upperside may thus be strongly or lightly marked. (vide PI. 6, figs 51-52). Underside. The pattern may be strong or weak on a variable ground colour of pale sandy ochreous to dark greyish ochre. The forms are not seasonal. Variation : a. With a strong pattern. Fore wing, cell with three rusty brown irregular lines, and two lines beyond cell end. Marks in median line on proximal side of discal bar rusty brown in 6, 5 and 3, then black in 2, double in ib ; the discal bar creamy ochre, paler in xa-ib ; the postdiscal series of stronger ochreous spots, curved in sub-apex, are ringed in brownish to black ; a double black streak at tornus in ib ; margin with indistinct ochreous spots. Hind wing, basal area more greyish ochre crossed by rusty brown lines ; the median line strong and in line with the median series of the fore wing, accentuating the inner edge of the discal creamy band, which is widest at the costa and tapering to the inner fold above anal angle ; on its distal side is a series of lunate ochre spots accentuated by rusty brown internally and by brownish grey distally ; submarginal ochre line distinct, accentuated distally by an orange admarginal line ; edge ochreous with narrow black edge and some white internervular fringing. Variation : b. The whole ground colour more sandy ochreous. Fore wing, pattern only slightly indicated except for the two black marks in ib and the tornal black line on a greyish ground.

The anal black dots on a greenish ground well represented. Intermediates between these two variations often occur. FEMALE. A somewhat similar variation occurs in the females though the differences are not so striking. Fore wing length 43-45 mm. Upperside. Differing from those of the nominate race and ghanaensis in its generally bolder pattern. Basal area bright rufous chestnut ; median black spots bold ; the discal and postdiscal yellow-ochre bars bolder, the two series well separated to 2, and slightly in ib ; the marginal rufous orange spots not so bold and may be obscured. Hind wing discal band wider, clearcut on inner border, some rufous shading on the outer border ; an occasional dark spot present in 6-5 indicating a slight separation of the discal and postdiscal rows in these areas.

Charaxes boueti rectans Rothschild & Jordan (PI. 6, figs 54-55, Map 5) Charaxes boueti rectans Rothschild & Jordan, 1903 : 540. MALE. Very similar in general appearance on the upperside to the dark form of male mac- clounii but darker, and at once distinguished by the straight arrangement in the formation of the fore wing postdiscal spots, without any curving toward the costa in the sub-apex. Fore wing length 35-36 mm. Upperside. Fore wing, ground colour rich rufous orange slightly darker at the bases, distal portion of the fore wing black. A large black mark at end of the cell ; the median black spots strong often extending to ib. The rufous orange discal spots tend to be separated in ib-3 by intrusion of the black median spots in these areas ; the post- discal rufous orange spots arranged in a straight line from costa to 2, then conjoined with the discal mark in ib, but often with some black scales indicating line of junction. Marginal rufous orange spots of increasing size from apex to tornus in ib. Hind wing basal area dark as in fore wing, clearly defined from the rufous orange discal band in the subcostal area where it is paler, by a dark line ; there is also a suggestion of a division of the band into discal and post- discal by a slight line in this area ; the band is relatively broad to area 4 then tapers toward the inner fold above the anal angle. The submarginal black band of fairly uniform width ends at the anal angle in the olive patch with its lilac and black dots ; there are also two white dots on the margin between the tails ; the rufous orange border, widest at 7-6, tapers gradually to between the tails ; margin black. Tails thin, upper 5 mm, lower 7-8 mm. Underside. Fore wing, ground colour fore wing ochre-buff, slightly greyer on the border. Cell with three distinct, rather strong, wavy lines, followed by a double mark beyond cell end ; median marks strong, rusty brown at costa and becoming strongly black in 2 and double or conjoined in ib. Post- discal series of spots silvery to ochre, accentuated on both sides by brownish to black, the black marks strongest in 2 and at tornus in ib with slight darkening in za. Hind wing strongly patterned on a buffish ochre ground ; a narrow brown line at sub-base ; median brown band strongly accentuated on either side by silvery white, strongest in disc but fading out at inner fold ; postdiscal line of lunules silvery toward costa but fading out above anal angle ; the postdiscal brownish marks shading to greyish on submargin followed by a silvery ochre ad- marginal line which shades to greenish at the region of the tails, more green at anal angle, enhanced by black dots, double at anal angle. Border orange to upper tail narrowly edged with greyish to black. There is no great variation on the undersides in a long series of males available. FEMALE. Fore wing length 40-42 mm. Upperside. Coloration generally very similar to that of macclounii, but pattern considerably different. Fore wing, base of wing bright rufous chestnut ; distal portion of wing black ; median black marks strong. Discal yellow-ochre spots smaller, and more discrete : two costal marks of about same size, one above the other, elongate-rectangular, spot at base of 4 small and triangular, spots in 3-2 ovoid, that in ib large, rectangular with indent on inner side, mark in la a streak. Postdiscal spots arranged in a straight line from subcosta to hind margin, yellowish ochre to 3, then more rufous to hind margin, contiguous to but contrasting with the discal marks in same area. Admarginal spots orange- ochre from apex to hind angle in ib, where the spot is double. Hind wing, basal triangle darker and browner than fore, shading to greyish on the inner fold. Discal band narrow, ochre- yellow in colour, fading out toward the anal angle, flanked distally by more rufous postdiscal spots clearly defined at the costal end, ill-defined and merging into discal band in area 3 ; submarginal band black, wide but not strongly defined proximally but with white lines opposite the tails and at anal angle with its two black dots ; marginal border rusty ochre to lower tail, edged black. Tails long, orange at mid base, margins black, 7-9 mm. Underside. Generally similar to that of the male, with strongly contrasting pattern. Fore wing, ground colour in cell creamy ochre with three strong brown bars crossing it ; a double bar beyond, often U-shaped. Discal creamy marks strongly accentuated proximally by dark brown to black median lines, 230 V. G. L. VAN SOMEREN double in ib ; postdiscal straight row of spots silvery ochre to silvery white accentuated on both sides by black, particularly in 2 and at tornus in ib ; admargin with ochreous lunules, clearly marked as a rule. Hind wing, basal area with strongly marked sub-basal and median bars forming a V enclosing a silvery line slightly edged in black. Discal band clearcut silvery whitish on inner border, more buffish grey distally, where it is outlined by an irregular tapering silvery line on the proximal side of the darker submarginal line, which extends to just above the anal angle ; admargin with silvery creamy lunules with black dots in spaces between the tails ; anal angle with greenish ground colour and two black dots ; margin golden-ochre shading olive toward the anal angle, lightly margined in black and white. Range : S.W. Ethiopia to Sudan and northern Uganda ; Karamoja and Metu, West Nile. Associated with areas of Solid Bamboo in savannah or low rockv hills.

Charaxes boueti alticola Griinberg ; Jackson, 1957 : 66. As will be noted from the above synonymy and the brief reference in the introduc- tion to this insect, some difference of opinion exists as to its status. My personal view is that it is a member of Group 2 of this species-complex, allied to boueti redans, since both are characterized by the almost straight arrangement of the postdiscal spots in the fore wing pattern in both sexes. Moreover, it will be noted that the underside coloration and pattern conform to that of other members of this species. Upper and underside coloration is variable, but the pattern is constant. FORM i. MALE. Fore wing length 35-38 mm. Upper side. Fore wing, ground colour at base bright rufous chestnut ; distal portion of wing black or blackish brown. A large quadrate black mark at end of cell followed by large median black marks which extend to the hind margin at i a. Discal rufous orange spots well separated and in almost a straight line except for that at base of 4, which is set well in, the mark in za and in lower part of ib extended distad and may be in contact with the postdiscal spots in these areas ; postdiscal rufous orange spots in an almost straight line from subcosta to la-ib, these spots usually well separated. Admarginal rufous orange spots large and distinct. Hind wing, basal area dark blackish brown, fading to greyish and buff on the inner fold. The discal band is narrow and pale orange to white at the costa widening in areas 5-2, where it is white in colour ; there is no indication of postdiscal spots but the band merges into the rufous orange zone, which is flanked by a row of contiguous black marks in the submarginal line ; border rufous orange, edged black ; anal angle with greenish spots ringed in black. Tails orange at base, black-bordered, short, thick at base 4-5 mm. Underside. Fore wing ground colour, greyish ochreous, paler in the cell and base of ib, usual rufous lines in the cell and at cell end ; discal and postdiscal spots barely indicated and separated by a series of brownish, rather dyslegnic marks from costa to ib ; a dark U-shaped mark, sub- basal in ib with a vertical double brownish mark at tornus. Hind wing, ground colour greyish ochre, base with a slightly darker greyish brown area, adjacent to the darker median band form- ing an open V and enclosing a silvery bar, the outer arm accentuated by narrow brownish edges ; the silvery discal bar is comparatively narrow, extending from costa to above anal angle, where it turns in toward the inner fold ; this bar narrowly edged distally by a narrow brown line ; postdiscal lunules hardly visible ; submarginal zone slightly greyish but hardly differentiated from the paler marginal border, which is narrowly edged with black ; anal angle with lilac and black dots on a greenish ground. REVISIONAL NOTES ON AFRICAN CHARAXES 231 A slight variation of this form is characterised by its generally paler, more orange colour and less deep black in the fore wing. The hind wing, though dark at base, is brighter orange over the distal portion and the submarginal black spots are smaller and well separated. The under- side also exhibits a general paler colour, but the silvery bars are strong. FORM 2. Variation : a. A very dark form in which the basal area is the same colour as the distal portion of the wing, both being a very dark chestnut. The discal and postdiscal orange spots stand out in the darker ground. In the hind wing the basal triangle is very dark brownish black, but fading to greyish then buff on the inner fold. The white area of the discal bar in strong contrast, its upper portion may be whitish or all orange ; the submarginal spots are larger and contiguous ; the ocelli at the anal angle strong ; the marginal border darker rufous chestnut, edged in black. Underside. Ground colour greyish ochre or putty-coloured. Discal spots ochreous and separated from the postdiscal series by a wide band of chocolate from costa to ib. Submarginal area of wing greyish ochre with almost complete suppression of the marginal lunules ; the sub-basal U-mark in ib chocolate and the tornal double vertical mark strong. Hind wing pattern as in Form i, but with only the proximal discal band, silvery. The sub- basal area divided up by rufous lines especially in the inner fold. The rest of the pattern as in Form i, but stronger. Variation : b. The ground colour is more greyish ochre, except in the fore wing cell, which is buffish ; the discal spots are obscured in the upper portion ; the postdiscal spots also slightly obscured but the brownish intermediate band is stronger up to ib. On the hind wing, the pattern is stronger, the sub-basal and discal bands strongly silvery, the latter with dark brownish edges, but the pattern in the postdiscal zone and margin rather obscured. (PL 6, figs 56-57.) FEMALE. Fore wing length 42-45 mm. There are two forms. FORM i . Upper side. The base of the fore wing is chestnut and in contrast with the blacker distal portion of the wing. There are indications of two dark spots in the cell ; median black spots distinct. The discal creamy spots are arranged as in the male, well separated up to la ; the postdiscal spots in a straight line from apex to ib are slightly more ochreous ; marginal spots ochreous. Hind wing basal area brownish black to greyish on inner fold. Discal band white, widest at costa to 3, then tapering to above anal angle. Postdiscal spots, contiguous in 7, are clear in the upper half but fading out toward area 4. Submarginal zone black, with olive anal mark with black dots surmounted by white to lilac lines well developed ; border of wing rufous brown, ornamented with distinct internervular ochre streaks. Underside. Fore wing, pattern very bold, and reminiscent of rectans. The ground colour is completely broken up by a series of more or less parallel vertical bars. Cell creamy, crossed by three wavy rusty bars ; the discal creamy spots, as above, divided from the postdiscal straight series by a rusty brown band extending from the costa to upper part of ia, flanked distally by dark marks, ib-3 and by a greyish ochre submargin in which the creamy ochre spots show up plainly. The creamy ochre line of spots are slightly silvery on margin. Hind wing, basal area greyish brown, joining up with the median bar toward the inner fold, which has three parallel brown lines. The basal and median bars outlined with darker rufous brown, the intervening creamy bars and the discal bar strongly silvery, as also are the series of creamy spots in postdiscal line, outlined distally in blackish which is continuous from costa to anal angle ; submarginal band is complete and greyish brown ; the admarginal ochreous lunules distinct, accentuated proximally with black and distally with double rusty brown spots ; edge black and white. FORM 2. Upperside. Fore wing, ground colour is a deep brown-black, the basal area only slightly browner. The discal and postdiscal creamy spots well separated ; the admarginal spots richer rufous but rather indistinct toward the apex. Hind wing basal area brownish black, browner toward costa. The inner fold greyish ochre. The discal band white, widest at costa then tapering from 3 to the inner fold. Postdiscal white spots distinct in upper portion of the line, then becoming obscured. The admarginal band rufous, with distinct ochreous internervular streaks. Underside. Similar to form i, but pattern stronger and light areas more silvery.

Syn. n. Charaxes lasti Grose Smith ; Talbot, 1932 : 9. Described as a species, this insect has, in varying degree, been linked with Charaxes boueti Feisthamel, because of its somewhat general resemblance to that species. (See Talbot, 1929 : 148.) Since the two overlap to a considerable extent, and do not interbreed, they must be considered distinct species. Moreover, they have different habitats and food plants, lasti laying on Julbernardia, Macrolobium and Afzelia, Caesalpinaceae, and boueti on species of Bamboo, Gramineae. The wing-antennae ratio is different (teste Dr van Son) . The shape of the two insects is different, in lasti the fore wing being less elongate, but outer border more incised ; the hind wing is more rounded on outer border but margin is more serrate or dentate at vein ends. The upper and undersides are subject to considerable variation, which is not seasonal. There are two forms in both sexes, a strongly marked form and a lightly marked one. These occur in about equal numbers, irrespective of season, and there are many intergrades. MALE. FORM i. Fore wing length 35-38 mm. Upperside. Fore wing, general colour rufous orange, slightly darker at the base, distal border of wing black. A rounded black spot beyond end of cell conjoined to or separate from a black line at end of cell ; median black marks in 6-5 larger and rounded or elongate, spots in sub-bases 3-2 and an indication of a mark in ib. The discal and postdiscal rufous orange bands separated in the subapex by a solid black mark in 7-6, a slightly smaller spot in 5, a streak in 4 and smaller spots in 3-2, otherwise the bands are conjoined. The upper postdiscal spots are arranged in a curve. Marginal border black with rufous orange spots on margin increasing in size from apex to double mark in tornus at ib. Hind wing, basal area slightly darker, sometimes with a dark costal triangular mark or line defining the costal inner edge of the discal band, which may be paler, the rest of the discal band ill-defined proximally especially toward the inner fold which is pale and buffish in its upper half. The submarginal black band, widest at its costal end where the spots are contig- uous, narrows rapidly, the spots decreasing in size and well separated. The anal angle olive- green with double lilac and black dots. Marginal border rufous orange, narrowly edged in black ; margin serrate at veins. Tails thin, upper 5 mm, lower 6-7 mm. Underside. Varia- tion : a. Fore wing, ground colour rufescent greyish with slight vinaceous tinge, paler in the cell and mid area of la-ib ; cell with three rusty transverse lines, a double or U-mark beyond. Discal and postdiscal series of ochreous spots hardly indicated, except for rusty lines on margins ; margin without spots but tornal mark consisting of two triangular horizontal black marks, edged with bluish grey, strong, double black lunate mark sub-basal in ib strong. Hind wing ground colour as fore, basal half with faint rusty lines ; discal area crossed by an almost straight silvery white bar proximally edged in black, and on its distal side, faint greyish white lunules followed by an irregular zigzag rusty band in postdiscal zone. Submargin slightly more greyish REVISIONAL NOTES ON AFRICAN CHARAXES 233 with distinct buff-white dots from tornus to anal angle, which is greenish with two black dots : edge of wing rusty, with slight black fringe and whitish bases to the serrations and tails. Variation : b. The fore wing very similar to var. a, or even more uniform, the hind wing less strongly patterned, the discal silvery line almost lacking, but the dark line on distal edge, strong. MALE. FORM 2. Upperside coloration and pattern of fore wing much as in form i but ground colour slightly paler, the marginal black border less strong, especially in the hind angle, so that the large marginal orange spot merges with the orange of the postdiscal bar in ib & la. On the hind wing the submarginal black spots are missing or only slightly represented, except for the two at upper angle. Underside. Variation : a. Ground colour more ochreous, less greyish vinaceous, so that the pattern shows up very distinctly. In the fore wing the rusty brown lines are strong in the basal half ; the discal and postdiscal bars are indicated more strongly. The two black lunules sub-basal in ib enclose greyish spots, and the tornal black marks are strong. In the hind wing the rusty lines show up more on the paler ground ; the silvery line is broader and proximally lined with black ; the postdiscal pale lunules are stronger while the submarginal rufous wavy line is strong ; the border more greyish ochre, the edge more rusty. Variation : b. Ground colour is more rufescent grey with a vinaceous tinge ; the pattern is almost suppressed except for the conspicuous black lunules enclosing grey in sub-base ib, and the tornal black mark is strong. On the hind wing the pattern is subdued except for the narrow silvery discal line. Intermediates are common. (PI. 7, fig. 60) FEMALE. There are two main forms with many intermediates ; they occur at all times and are not seasonal. FORM i. Fore wing length 39-42 mm. Upperside. Fore wing, base bright rufous orange ; distal portion of wing brownish black. Median black marks, one heavy rectangular subcostal at sub-bases 7-6, a mark at end of cell separate from or contiguous with marks sub-basal in 3-2 and slightly represented in ib. Discal and postdiscal series of spots yellowish ochre, spot in 4 in discal line set well in, the postdiscal spots shaded with rufous distally, conjoined with discal marks in la-ib, slightly separated in 2, the remainder free. Border black with rufous orange marginal spots, increasing in size from apex to ib at hind angle. Hind wing basal area greyish rufous, paler on the inner fold, sharply defined from the yellowish ochre band at the costa by a narrow black line, distal border of band shaded with rufous. Submarginal black band strong, consisting of contiguous marks angled on outer border ; anal angle greenish with two black dots surmounted by lilac-white lines ; marginal border orange rufous, edged with black ; margin serrate at vein ends. Tails long and thin, upper 7 mm, lower 9 mm. Underside. Variable. Fore wing, base greyish ochre, cell paler ochre, crossed by well marked rusty lines, one sub-basal, one in mid area, the third at end of cell, this last sometimes united to black mark at base of 4 ; median lines strong, rusty coloured in upper half then black in sub- bases 3-2 and ib, which has a sub-basal black line. Discal and postdiscal series of spots as above but less strong ; submarginal border more greyish with brownish spots along distal edge of postdiscal row, becoming black in 2 and, at hind angle where the black marks are, two hori- zontal triangles on a bluish grey ground. Hind wing basal area greyish ochre with vertical rusty lines in sub-base ; median line rusty brown by a silvery white line defining the discal creamy yellow bar, which is broad at the costa, tapering rapidly to another silvery line which runs parallel to the median line, both taking an angle toward the inner fold above the anal angle. Postdiscal zone with large diffuse rusty spots, which extend from the costa to above the anal angle ; submarginal band greyish ochre with a satiny sheen, distally bounded by a series of whitish elongate marks accentuated distally by rusty lunules ; border with orange-ochre lunules outlined in whitish ; extreme edge black ; margin serrate at veins. FORM 2. Upperside. Paler and brighter than form i, the basal area a clearer orange, the discal and postdiscal spots larger and more confluent ; the outer border of the postdiscal spots extended more distad, so that the black border is more restricted, but the marginal spots are larger. Hind wing paler, the basal area not defined and paler ; the discal yellow-ochre band merging into a broad bright rufous orange zone which carries a series of submarginal dyslegnic 234 V. G. L. VAN SOMEREN well separated dark spots, well defined from the more orange border with black edge. Tails long and thin. Anal angle pale olive-green with usual black spots. Underside. Paler and more ochreous ; pattern less strong in the disco-postdiscal bands ; border less dark, but greyish lunules more satiny. There is also a satiny patch at the costa between the disco-postdiscal creamy spots. Hind wing pattern less strong ; the median silvery line narrower ; the discal band less defined ; the rusty postdiscal zigzag narrow but clear ; the border less dark ; the admarginal zone more ochre and the margin rusty with narrow black edge. Range : In coastal forests from Tana River to Shimba Hills, Kwale & Dalgube, Kenya to the Pugu Forest & Tanga district in the Usambara Mts, Tanzania. Biological notes, by D. G. Sevastopulo OVUM. Shape as is usual in the genus, spherical, with a fluted and flattened top. Colour very pale green when first laid, developing the usual brown ring round the top after twenty-four hours. Later the whole ovum becomes speckled with brown, the ring broadens and there is a brown dot over the micropyle. Laid singly on the upper surface of a leaf of the food-plant. Laid 5.X.64, hatched g.x.64. IST INSTAR. Head very dark mottled brown, the horns very short and stout, the upper pair more or less straight, the lateral upcurved, the tips paler.

Head brown, the facial disc green, the horns paler, fairly straight, a pale stripe, edged behind with blackish, from the base of the lateral horn to outside the jaws. Body rather dull green, minutely shagreened with white. A subdorsal series of white specks and also a lateral series consisting of an outer anterior and an inner posterior on each somite. Dorsal mark on the 6th somite white, outlined with black, roughly semicircular in shape, the straight edge anterior and produced into three lobes. Some larvae with an additional white dot outside the main mark. Some with a similar additional mark on the 8th somite, and a few with an additional elongate dorsal bar on the loth. Anal processes small, white and joined by a trans- verse white bar, the processes and the bar itself edged below with black. Moulted y.xii.64. (PL 11, fig. 93.) FINAL (STH) INSTAR. Head green, speckled minutely and sparsely with white, and outlined with pale pinkish lavender ; horns slate-grey in front, greenish behind, and studded with minute black points, upper pair fairly long, straight, divergent, lateral pair slightly stouter and shorter, straight, the points between the horns black ; a blackish line behind the pinkish lavender margin. Body fairly dark, bright green, minutely papillated with yellow and with a series of slightly larger white specks laterally. Dorsal mark on the 6th somite roughly semicircular with the straight edge forward and expanded into three rounded lobes, a white spot lateral to the main mark, which may be separate, conjoined or absent. Mark on the 8th somite roughly diamond-shaped, with or without a white spot lateral to it. loth somite with a short longitudi- nal dorsal bar, which may be absent. A pale sublateral line. Venter, legs and prolegs glaucous green. Anal claspers and last two segments of venter dull purplish. Anal somite slightly concave, edged with a white line, below which is a purplish one. (PL n, fig. 95.) REVISIONAL NOTES ON AFRICAN CHARAXES 235 Some larvae undergo an additional moult, a thing I have not observed before in Charaxes. These larvae are slightly smaller than normal in the 4th instar, they undergo no change in appearance in the 5th instar except a slight increase in size, and the 6th instar is similar to the normal 5th, but very slightly larger. The extra moult appears to have no sexual significance. The larvae turn dull olive-brown when preparing for pupation, the dorsal marks become slightly tinged with pinkish. PUPA suspended by the cremaster. The dorsum of the thorax and the first two abdominal somites pale lavender, shading into pale brownish olive posteriorly, this area tapering towards the cremaster and shading into darker laterally. A fine, darker dorsal line on the thorax. Lateral area whitish, very faintly tinged with pinkish, due to numerous fine punctures filled in with that colour. Wing cases similar, with an oval, olive-brown spot on the outer margin below the tornus. Leg sheaths with an indistinct olive-brown spot. The pupa is very similar in appearance to that of Charaxes protoclea Feisthamel, azota Hewitson. The pupa is dimorphic, another form having the pale lavender areas very pale blue, the olive-brown areas olive-green, and the areas faintly tinged with pink in the first described form, very pale green. (PL n, figs 96, 97.) Food-plant. Julbernardia magnistipulata Harms, and Macrolobium coeruleum Harms, (both Caesalpinaceae) . Dr van Someren (Butterflies of Kenya <§• Uganda) records seeing a female laying on Afzelia quanzensis, and females also lay freely on this in captivity. Newly hatched larvae however, usually refuse to eat Afzelia, but if they do, fail to thrive and do not get through the first moult. Described from larvae reared from ova laid by a female caught in the Marere Forest, of which one pupated 22.xi.64 and a male emerged 2.xii.64. Another brood, reared from ova laid by a Kwale-caught female, were without dorsal markings up to the 4th instar, when they developed a rough diamond-shaped mark on the 6th somite (PI. n, fig. 94).

Charaxes richelmanni Rober, 1936 : 578. Charaxes fallax Richelmann ; Carpenter, 1937 : 9^- The superficial resemblance of this insect to some forms of Charaxes eudoxus has given rise to some confusion ; thus, when Holland, 1920, reported on the Lepidoptera of the Congo, he recorded three specimens taken at Medje, as Charaxes eudoxus eudoxus Cramer, distinguishing them from Charaxes mechowi Rothschild (also taken at Medje) which he considered to be a distinct species, by ' the great reduction in width of the silvery bands on the lower surface of the hind wing '. This identifica- tion was accepted by Carpenter (1937), who suggested that the reduction of the silvery lines might indicate that the specimens were transitional towards eudoxus cabacus ab. amaurusl I have examined these specimens and consider them to be, without doubt, richel- manni Rober, —fallax auctt. MALE. Fore wing length 37-38 mm. Upperside. Fore wing, base deep chestnut with a slight vinaceous bloom, extending from the cell end to sub-bases of la-ib, shading into the black of the discal zone and the distal part of the wing ; there may be an extension of the black into the cell end. The postdiscal rufous orange bar is almost complete, extending from the hind margin in xa to 6-7, rather narrow and with little reduction in the size of the spots, the REVISIONAL NOTES ON AFRICAN CHARAXES 237 238 V. G. L. VAN SOMEREN spots in la-ib 4 mm, conjoined, the remainder well separated, the upper ones more rounded ; marginal rufous orange spots large and distinct, extending from ib, with a double spot, to the apex. Hind wing basal triangle darker than fore, almost black, with a suggestion of chestnut at base ; the postdiscal orange band, widest and pale at the costa, narrows and becomes shaded over as it approaches the inner fold above the anal angle, thus not sharply denned on the prox- imal border ; the submarginal black band starts just short of the costa, widens in 7-5, thence to anal angle where there are two lilac spots, the inner border of the band ill-defined but the outer clear-cut and dentate ; border of wing rufous orange, of almost equal width tapers at anal angle, edged black, margin serrate and the anal angle rather more marked than in eudoxus ssp. Tails thin and sharply pointed, 3-4 mm long. Underside. Fore wing, ground colour of basal half up to postdiscal line bright chestnut ; cell and just beyond with four transverse black lines outlined in silver ; a silver and black transverse bar sub-basal in 6-7 in discal line, followed by bolder black marks of irregular shape finely outlined in silver sub-base of 3, a double or con- joined mark in 2, a larger black mark in ib extended basad, and a smaller mark in la. Post- discal bar tawny orange in ia-3, finely outlined proximally in white, the spots above with greater amount of white follow the contour of postdiscal bar of above ; this is outwardly bordered by a series of black triangular horizontal marks, large at tornus and decreasing in size to the apex ; these marks are outlined distally in greyish, this greyish colour extending distad along the veins, thus separating the orange lunules on the border of the wing. Hind wing, ground colour in basal area to postdiscal band bright chestnut ; the inner fold with three vertical black lines edged white, the upper discal area with a darker chestnut solid V, boldly outlined in silvery white ; the postdiscal zone distally outlined in silver from costa to above anal angle, with a white line at mid point connecting to the outer arm of the discal V. Zone corresponding to the black submarginal bar of upperside, here represented by dark chestnut and black horizontal triangles, apices distad, finely outlined in silvery grey ; an admarginal line of contiguous lilac marks finely accentuated with black and ending in the olive anal angle with lilac ' eye-spots ', sets off the tawny orange border, which is edged in black finely accentuated white proximally. The FEMALE is unknown. Range : Cameroon, Central African Republic, Moyen Congo, Upper Congo to Medje in the Ituri area. Charaxes eudoxus Drury and its subspecies The species Charaxes eudoxus has a very wide range, extending from the forested areas of West Africa eastward through the Congo to northwest Kenya and the eastern shores of Lake Tanganyika and to the northern block of Zambia. Its distribution tallies more or less with the Zones 5, 7, & 8 as shown on the Vegetational Map published by UNESCO in 1958, and described as ' moist forest at low elevations ' and ' forest-savanna mosaic '. It is not surprising to find that within this vast area, the species has evolved into several ' aggregates ', not all of which are sharply and clearly differentiated, and in some cases there is a transition from one group to another. Poulton (1929) dealt with some aspects of this subspeciation, based on specimens then available, when he described the subspecies amaurus from north-west Kenya, Mt Elgon area. This was followed by a more detailed survey by Carpenter in 1937. This survey was carried out in order to ascertain the ranges of the several subspecies, their validity, and relationship to each other, and to describe a race from the western shores of Lake Victoria to which I had drawn attention in 1936. Carpenter went to considerable length in trying to find stable characters by which the several races REVISIONAL NOTES ON AFRICAN CHARAXES 239 could be distinguished, selecting certain features which he tabulated (Op. cit. p. 86) and comparing these measurements in the several races then recognized. These comparative measurements were not entirely satisfactory or conclusive, because of the degree of pattern variation in each race ; moreover, exact topotypical material in sufficient numbers was not available for a basis. It is also regrettable that in this review some of the plates do not figure topotypical specimens. It is surprising to note that Carpenter accepted Holland's identification of three males taken at Medje, North Ituri, Congo, as eudoxus eudoxus Drury (vide Carpenter, I937 : 97 > distribution of races) and did not take the trouble to examine these specimens. They were kindly sent to me by the late Dr R. M. Fox of the Carnegie Museum, Pittsburgh, U.S.A. and they are in fact Ch. richelmanni Rob. =Ch. fallax Rich., Carpenter et al., which is a distinct species, with distinctive genitalia, occurring within the range of Ch. eudoxus mechowi in the Congo. Examples of mechowi were also taken at Medje, which Holland considered to be a distinct species, unrelated to eudoxusl In spite of extensive material which has accumulated since Carpenter's review, one is still hampered by the lack of topotypical material of both sexes. The division which follows must therefore be taken as tentative. Charaxes eudoxus eudoxus Drury (PI. 8, figs 67-68, Map 6) Charaxes eudoxus Drury, 1782 : 44, Index, pi. 33, fig. 4. Charaxes eudoxus Drury ; Carpenter, 1937. MALE. Fore wing length 38 mm ; outer margin slightly incurved. Upper side. Fore wing, basal triangle dark chestnut, with slight chestnut along costa to mid point, merging into the black ground of the distal portion ; slight encroachment of the chestnut colour toward end of cell. Postdiscal bar paler and more developed than in other races, extending from the hind margin to 7, widest at ib (5 mm), the spots gradually decreasing in size and becoming more discrete from hind margin to 7 ; margin with distinct rufous orange internervular lunules, double at ib and extending to the apex. Hind wing basal triangle darker chestnut inclining to blackish towards costa ; discal band orange-rufous, paler and widest at costa, slightly constricted at 7, then widening slightly and tapering toward anal angle but not crossing the inner fold ; outer edge straight, contiguous with the black postdiscal band, which extends from just short of the costa to just above the anal angle, of about even width to area opposite tails, then narrowing slightly, outer margin dentate. Border paler rufous orange ; margin black. Tails relatively short, upper 4 mm, lower 3 mm, black. Anal angle black with slight indication of one or two purple-blue spots. Underside. Fore wing, basal ground colour chestnut in subcostal area to subapex, crossed by black lines strongly bordered in silver ; bases of 10-3 with large black marks edged in silver and bordering the postdiscal bar, which is ochreous on inner edge but orange distally, bordered distally by a black tapering zone, widest at hind margin and carrying bluish grey triangles and lunules to subapex ; border with orange lunules separated by black. Hind wing basal area chestnut, traversed by narrow black lines bordered in silver, most pronounced in the discal line which is Y-shaped at the costa, extending to and widening above the anal angle, bordered outwardly with chestnut, interrupted on the outer postdiscal line by slightly darker chestnut triangles outlined in greyish olive, accentuated basally by a series of black lunular marks edged distally with purplish grey and bordering the paler chestnut border which extends to anal angle which is olive, carrying two violet- white dots ; edge black, bordered internally with purple-grey. 240 V. G. L. VAN SOMEREN Description based on a male specimen from Sierra Leone, Freetown. (Univ. Mus. Oxford.) FEMALE. Fore wing length 45 mm ; outer margin of wing less incurved than in the male. Upperside. Fore wing, basal area paler chestnut and more extended towards the discal line and in the cell, where there are two dark marks, one subcostal and the other at the cell end ; rest of wing black, traversed by an ochreous orange bar in the postdiscal line, widest at the hind margin (8 mm), gradually tapering to 7, but there are indications of orange scaling sub-basal in 5-7 in the upper discal line. Margin with small orange internervular spots. Hind wing basal area darker chestnut, shading to brownish towards costa ; orange discal band wide, slightly paler towards costa, of equal width, 7 mm, to upper tail then gradually decreasing to above anal angle, inner edge almost straight but outer edge slightly dentate ; outer border pale tawny orange ; anal angle black with two lilac spots ; edge strongly black ; tails short, rather stumpy, upper 3 mm, lower slightly shorter. Underside. Pattern as in the male, but bolder ; the discal bars of both wings wider and paler, more whitish ochre, bordered orange distally. Description based on a female taken at Freetown, Sierra Leone. (Univ. Mus. Oxford.) Range : Sierra Leone, Ghana, Ashanti ; ? Ivory Coast ; thus not crossing the Togo-Dahomey divide. Records from Buea, Cameroons doubtful, since south- eastern Nigerian specimens are not nominate eudoxus eudoxus. Hollands' record from Medje, Ituri, accepted by Carpenter, is erroneous (vide introductory remarks). Charaxes eudoxus mechowi Rothschild (PI. 8, figs 69-74.

The variations are not associated with definable areas, but turn up here and there. It is advisable therefore to quote Rothschild's description (1900) of the type of this race. MALE. 'Length of fore wing 43 mm. Band of fore wing above about 6 mm distant from tip of vein SM2, strongly tapering costad, stopping at SC5, four upper spots small, luniform (type) or rounded elongate. Black postdisco-marginal band of hind wing interrupted at veins R3-M2, or Mi & M2, anteriorly as wide as or a little wider than posteriorly, considerably narrower than the ad- marginal band. On the underside the submedian and median bars Mi-M2 very heavy, patch- like ; black costal and subcostal bars of submedian and median series absent.' This description is quoted because no topotypical North Angolan examples are available to me. However, I have a specimen from the southern Kasai which agrees with the type, and a comparative description of this with nominate eudoxus is desirable. The main features on the upper surface of the male are : basal area of fore wing brighter reddish chestnut ; the distal portion of the wing blacker ; the postdiscal row of rufous orange spots much reduced in extent, widest in ib, it tapers rapidly to 3, remainder of spots vestigial. Hind wing basal area as in nominate race ; disco-postdiscal rufous orange band wider, encroach- ing on the submarginal black bar from above anal angle to 5, thus reducing this bar in its lower half very considerably ; the marginal rufous orange border wider and richer ; the marginal black narrower ; the tails longer and thinner. REVISIONAL NOTES ON AFRICAN CHARAXES 241 Area i Northern Angola, Kasai and western Katanga, Moyen Congo, Central African Republic, Cameroons to eastern Nigeria. Dominant form. MALE. Fore wing length 39-40 mm. Upperside. Fore wing, basal area reddish chestnut ; distal 2/3rds of wing black, extending from the proximal edge just short of the apex of the cell to just internally of the postdiscal orange bar on hind margin ; this bar richer in colour than nominate eudoxus, less wide in la-ib and tapering rapidly to 2-3, then represented by spots of decreasing size to 4, obsolete beyond. Margin with small rufous orange spots, double in ib, and extending to the apex. Hind wing basal area chestnut, shading to blackish toward costa ; the rufous orange discal band, very slightly paler at the costa where it is 6 mm wide, is strongly indented on its inner border at 6-7 then expands slightly, to taper again to above the anal angle, the band is thus of uneven width and ill-defined in its lower half ; the submarginal black bar is widest at its upper half and then represented by contiguous spots from 5 to the anal angle where the last spot has two lilac spots. Border mainly rufous orange of even width, but tapers slightly near the anal angle ; edge narrowly black with slight white fringe in interspaces ; margin slightly serrate ; tails thin, upper 4-5 mm, lower 3-4 mm. Underside. Fore wing, basal area up to postdiscal zone, chestnut, but basal half of costa silvery white ; cell and sub- bases 5-7 with irregular black marks outlined in silver ; a large elongate black mark at base ib filling the whole area up to the postdiscal zone, thinly outlined in white ; space above in 2 with two rounded black spots outlined in silver, one basal, the other touching the postdiscal line where there is a smaller black mark similarly outlined ; postdiscal zone orange in la-ib, becoming more rufous to sub-apex and ornamented with greyish loops decreasing in size up to costa ; border of wing rufous chestnut in apical half but with black triangular marks con- tiguous in ib-2 and with greyish between apices on orange ground. Hind wing, basal area rufous chestnut with a V-shaped silvery mark, apex toward inner fold where there are three black lines widely bordered in silver ; a slightly curved silvery line extends from costa to above anal angle, touching the outer angled arm of the V-mark ; the postdiscal zone slightly darker and carrying a series of greyish V-marks apices directed outward, followed up by a line of broken dark marks abutting on the more reddish border which is edged outwardly in black ; anal angle more ochreous olive, with a large and small lilac ' eye-spots '. FEMALE. Upperside. Somewhat similar to nominate female but with brighter chestnut at base ; fore wing bar narrower and placed nearer to the margin which has larger orange spots. Hind wing, generally brighter orange, with discal band considerably wider and more curved on outer edge, thus reducing the width of the postdiscal band which, though slightly irregular on the inner edge is dentate on the outer, the band slightly decreasing in width toward anal angle where it expands slightly ; border wider than in nominate eudoxus, more uniform in width and more narrowly edged in black. Tails longer, more pointed, upper 6 mm, lower 5 mm. Under- side. Basal areas of both wings bright chestnut with similar silvery bars and black marks as in the male, but fore wing bands more orange, darkening slightly toward apex of fore wing ; tornal black marks strong. Hind wing border brighter rufous orange. These descriptions are based on specimens from southern Kasai, and are applicable to a large majority of specimens from further north, but individual variation is considerable. In the area from Leopoldville to Cameroons and east to the Semliki Valley we encounter an aggregate which, though conforming to the general pattern of mechowi, differs mainly in the extent of the rufous orange spots in the fore wing bar and the shape and extent of the black submarginal bar in the hind wing. Variation : a. The fore wing bar though narrow, consists of rufous orange spots of decreasing size from ib to 6 ; the marginal spots larger than in nominate mechowi. The hind wing basal area blacker toward costa ; the submarginal black bar slightly heavier though similar in shape. Variation : b. Upperside generally darker, the fore wing postdiscal bar being limited to 242 V. G. L. VAN SOMEREN rather obscure rufous spots in ra-ib ; hind wing pattern as usual but darker. Ouesso, Moyen Congo (Jackson). Area 2 The Congo forests east of the Congo River to Ituri and the Semliki Valley. In this area there is a noticeable tendency towards increase in size and darkening of colour, but the pattern is, in the vast majority, that of mechowi. Area 3 Western Uganda, Kigezi Province, Kayonza forests south of the Ishasha River. In this aggregate, males and females are more intensely coloured above and below. MALE. Upperside. Fore wing postdiscal bar is more extended, the rufous orange spots usually reaching 5, occasionally 6, but a noticeable feature is the narrowness of the bar in la, ib-2, so that there is not the rapid tapering of the bar from the hind margin, the marginal orange lunules strongly developed. Hind wing, the black costal patch in the basal area is stronger, thus contrasting with the upper end of the discal band which is here pale and wide, but constricted in 7 then widening to 4 and tapering to above the anal angle ; the submarginal black bar is strong and similar in form to that of mechowi, more solid and in its widest upper section, the black is extended distad into the rufous orange border along the veins ; the black edge is well marked. Underside. General pattern similar to typical mechowi but stronger. FEMALE. Upperside. Generally more richly coloured, the reddish chestnut at the bases of the wings stronger. Fore wing, rufous orange bar is deeper in colour and the whole bar is narrower, especially in la, ib & 2, and extends to 6 or even 7. There is often an orange spot subcostal in 7 and another mark beyond end of cell. Marginal spots pronounced. Hind wing, discal band, pale at the costal end and narrow, widens in 5, then gradually tapers to above the anal angle, reaching the inner fold ; pale in the mid area, it is strongly shaded orange on the distal border ; submarginal black bar stronger than in mechowi, the anal angle with two distinct lilac spots ; marginal border richer rufous orange, olive at anal angle ; edge black with white internervular fringe. Underside. Pattern generally similar to typical mechowi but stronger. Range : Area i, northern Angola, Kasai and western Katanga, Moyen Congo, Central African Republic, Cameroons to eastern Nigeria. Area 2, Congo, east of the Congo River to Ituri and Semliki Valley. S.W. Sudan? Area 3, Uganda, Kigezi District, Western Province, in the Kayonza forests of the Ishasha River Valley. Note that this area (3) abuts on the Ruanda-Urundi and Lake Kivu areas. Charaxes eudoxus theresae Le Cerf (PI. 9, fig. 78, Map 6) Charaxes eudoxus theresae Le Cerf, 1932 : 405. Charaxes eudoxus theresae Le Cerf ; Carpenter, 1937, P^ 5- I have before me the <$ type and three <$ paratypes kindly sent to me by Dr P. Viette of the Paris Museum. Carpenter (1937) upheld this race, citing as diagnostic characters : Fore wing postmedian band very wide at base, (8 mm entire 1-2) rapidly decreasing in 2 to 2 mm ; beyond nerve 3 there are 3 spots, the last minute. REVISIONAL NOTES ON AFRICAN CHARAXES 243 Marginal spots smaller than in mechowi. The general lorm of the hind wing rufous orange band is broader than in mechowi ; the postdiscal black band also wider and less tapering. This description refers to the type. The paratypes show that in the fore wing, postdiscal bar is widest in ib, tapering rapidly to 3-4 ; marginal spots may be strong. Hind wing black submarginal bar variable, wide as in the type or reduced to a series of discrete spots in the lower half, but upper half with conjoined spots. The female is not known. This aggregate is thus unstable and shows a transition between mechowi and the Kigezi form. Range : The western shores of Lake Kivu. I have two specimens from the north-east shore of Lake Tanganyika taken at Kigoma. They are rather darker overall than Kivu specimens, but the fore wing pattern is very similar ; the hind wing rufous orange band is more restricted in 5-6, where the bar is at its widest, tapering rather rapidly to above the anal angle. The submarginal black bar is rather heavy in its upper half, then tapering to the anal angle which has the usual lilac-white dots. Marginal rufous orange border less wide, being encroached upon at the upper angle by the black bar. These Kigoma specimens are not mechowi but show an approach towards eudoxus of the Kigezi area and theresae. The female has not been taken.

The general impression of the upperside is that this insect might be a melanistic variant of cabacus. It was for this reason that I hesitated to apply a name to it in 1936, when it was represented by a single male. In recent years, and on different occasions, several males and females have been trapped in the Katera forest, near Sango Bay. The males are remarkably constant on the upper surface and the female is quite unlike those of other races of eudoxus, but both are subject to variation on the underside. MALE. Fore wing length 39-40 mm. Upperside. Fore wing, ground colour almost black, with a slight indication of deep chestnut at the base of the wing ; the postdiscal zone with a trace of rufous spots in la-ib, and occasionally a mere trace in 2. Margin with small rufous spots seldom extending to the apex. Hind wing with very obscured pattern ; basal area mostly black, a slight trace of a rufous chestnut band most apparent at the costa, but suffused over in the disc ; submarginal black band wide at upper end near the costa, then tapering slightly to the anal angle ; border narrow, dark rufous ; tails short and thick at base, 4-5 mm long, edge narrowly black. Underside. Pattern generally similar to that of cabacus, but chestnut ground colour over distal portion of wings suffused with a vinaceous bloom ; ad- marginal greyish triangles well marked in fore wing, marginal orange present only at tornus. Silvery lines and bars as usual in the species. 244 V. G. L. VAN SOMEREN An interesting variation has the outer border of both wings shot with bluish grey, due to increased size of the greyish admarginal triangles in the fore wing, and in the hind wing, beyond the submarginal chestnut area shot with grey, there follows a thin black line outwardly bordered with mauve and chestnut internervular lunules. Form resembling amaurus Poulton. Upperside. Fore wing, in this form the suppressed pattern is more noticable, the basal chestnut is slightly more extended, and the trace of the postdiscal bar may extend to 3 ; the marginal spots are larger. On the hind wing, the discal band is more apparent, and the submarginal black band correspondingly more sharply defined ; the rufous border slightly wider. Underside. Ground colour paler rufous, with practically all trace of the silvery lines wanting, or just slightly indicated, but black marks still present. (PI. 9, fig. 79.) FEMALE. Upperside. Bears a strong resemblance to the female of Charaxes lucretius Cr. but the fore wings are more pointed. Fore wing length 44-45 mm. Base chestnut, with an occasional paler subcostal mark at cell end, but extent of chestnut variable toward hind area, rest of wing black, traversed by a postdiscal row of creamy ochreous spots contiguous in la-ib, but free from 2-6, spot in 2 usually round, remainder rather ovoid ; margin with distinct rufous orange spots, double in ib, and extending to apex. Hind wing, basal area blackish brown, paler on inner fold ; discal band creamy ochre with rufous orange shading on distal border in lower half ; inner border with slight kink at 5, outer border almost straight ; sub- marginal black band strong, rather wide, with dentate outer border ; border orange-ochre ; edge black. Tails thin, 5 & 4 mm long. Underside. Very similar to male, especially the varia- tion mentioned above, but pale bands of upperside well represented below. Form resembling amaurus Poulton. Upperside. Basal area fore wing brighter chestnut ; postdiscal bar with creamy ochre spots more irregular in shape. Hind wing ochre band less shaded with orange rufous ; submarginal black zone bolder. (The resemblance to female lucretius is thus enhanced.) Underside. Reddish brown, devoid of silvery bars and lines, but black marks in fore wing strong ; bands of upperside strongly represented below. (PI. 9, fig. 80.) Range : Uganda, western shore of Lake Victoria in Buddu district in the Mala- bigambo forest area at Katera. Charaxes eudoxus cabacus Jordan (PI. 10, figs 83-84, Map 6) Charaxes eudoxus cabacus Jordan, 1925 : 288. Charaxes eudoxus cabacus Jordan ; Carpenter, 1937. [partim.]. When considering this race, we are faced with the problem of dealing with an aggregate which has evolved into two distinct ecological groups from west to east. This was remarked on by Carpenter (1937 : 89), but he was content to refer to the two groups as nominate cabacus Jordan. Furthermore, he drew attention to the fact that Jordan did not have a female associated with his male from Entebbe, but he mentions that I had described a female from Kitale in 1929 and figured it in the same journal in 1936, under the name cabacus Jordan. He therefore suggested that this insect should be considered the neallotype. The problem is further complicated by the fact that in 1929, Poulton described Ch. eudoxus amaurus as a distinct race from the Kitale district, S.E. of Mt. Elgon, the chief character of which was the total suppression of the silvery marks on the underside in both male and female. As quoted by Carpenter (1937 : 90), I sub- sequently bred a family from a known parent which contained examples of both REVISIONAL NOTES ON AFRICAN CHARAXES 245 amaurus and ' cabacus '. I therefore came to the conclusion that amaurus was a variety and not a geographical race, on the assumption that Kitale specimens were indeed cabacus Jordan. Having examined numerous specimens from both Entebbe and S.E. Elgon, I can confirm Carpenter's remark that material from the eastern areas differs from nominate Entebbe specimens. It is unfortunate that Carpenter should have figured an example of the eastern aggregate (Tiriki Hills) as typical cabacus (pi. i, figs 2 & 3), and not a topotypical example from Entebbe. Carpenter notes that some Entebbe examples ' come quite near to the new subspecies ...katerae from a locality further west, on the west coast of the northern part of Lake Victoria '. I therefore propose to deal with this complex as representing two distinct geo- graphical races, cabacus Jordan from the Entebbe area and amaurus Poulton from N.W. Kenya. MALE. Size generally smaller, fore wing length average 38 mm. Upper side. General colour as in more western examples (Toro and Kalinzu), but basal rufous chestnut slightly more restricted toward hind margin ; a black mark often present in the cell toward end. Postdiscal rufous orange bar very narrow in la-ib, seldom wider than 4 mm, the marks here contiguous, the remainder free and of decreasing size to 6 ; marginal spots well developed. Hind wing basal area chestnut shading to black over bases of 6-7 where it encroaches on the rufous orange discal band. The latter is slightly paler at the costa and kinked in 6, where it is narrow, widening slightly, but still comparatively narrow ; the submarginal bar is wide to 3 then taper- ing toward the anal angle ; thus the rufous orange border is narrow as a rule ; edge black. Tails short, 5 mm. Underside. General pattern as in mechowi, but chestnut ground colour paler, with full complement of silvery lines and bars ; black marks ib-2 moderately strong. FEMALE. No topotypical females are available for study. The female figured by Carpenter (1937, pls- 3 & 4> fig8- Io & Ioa) belongs to the eastern race. Range : Forests around Entebbe : Zika, Kisube, and ?

It is unfortunate that when Poulton described the race eudoxus amaurus, only one form was available to him. It is now known that there are two forms within this aggregate. If this aggregate is to be considered a valid subspecies, the name amaurus must be utilized for it. Since the original description applies to only one form, it would appear desirable to refer to the second form by an infra-subspecific name... form nzoia, described below. The nominate form of amaurus is comparatively common amongst the aggregate of N.W. Kenya. MALE. Upperside. There is little or no difference from males of the eastern block, but on the underside the characteristic silvery lines are entirely wanting or vestigial ; the black marks are reduced in size, but otherwise normal. 246 V. G. L. VAN SOMEREN FEMALE. Upperside. Identical with females of the eastern area, either with or vvithout rufous orange spots in subcostal area of fore wing. Underside without silvery lines. Form nzoia forma n. MALE. Upperside. Differs from the nominate cabacus by having the basal areas of fore and hind wing brighter chestnut ; the rufous orange bar of the fore wing not so restricted in the hind portion in ia-2, the remaining spots decreasing in size and reaching 3-4. The hind wing rufous orange band wider, not so narrow and suffused over in lower half, where it merges into the inner fold above the anal angle ; the black submarginal bar thus narrower in its upper half ; border slightly narrower. Underside. Pattern as in nominate cabacus, but black marks in fore wing less solid and large. FEMALE. Upperside. Fore wing basal area brighter rufous, black area in disc tapering rapidly and not reaching la, Subcostal area invaded by trace of rufous marks, one beyond cell and two smaller in 5-6. The postdiscal orange band is broad in la-ib, lessening in width from 2 upwards to 6, 7. Marginal spots strong. Hind wing basal area rufous without darkening toward costa ; discal band tawny orange, broad, widest in 5 then tapering to above anal angle. Marginal border relatively narrow ; tails rather short and stumpy at base, upper 5 mm, lower 4 mm. Underside. Pattern as in the male but pale bars on both wings conspicuous ; silvery lines less strong ; black marks in fore wing less strong. Holotype male. N.W. KENYA : Kitale, ix.i933. (PI. 10, fig. 87.) Allotype female. Same data. (PI. 10, fig. 88.) Distribution : Both forms occur in about equal numbers in the forested areas east of the Nile. Recorded localities are : Tiriki Hills, Kakamega, Kaimosi, Nandi, TransNzoia, in S.E. Elgon area, Kitale. Charaxes eudoxus zambiae ssp. n. (PI. 10, fig. 89, Map 6) The discovery of this very distinct subspecies extends the south-eastern range of Charaxes eudoxus very considerably. MALE. Fore wing length 39 mm. Upperside. Fore wing, pattern somewhat like eudoxus amaurus f. nzoia but distinguished by the duller basal chestnut and the much paler tawny orange bar, which extends from the hind margin where the marks are conjoined in ia-2, then as discrete spots of diminishing size to 6. Marginal spots large and distinct. Hind wing basal area chestnut, shading to black in the costal region and to greyish brown on the inner fold. Discal band pale tawny orange of about equal width almost throughout, then tapering toward the anal angle ; submarginal black bar wide, tapering only at anal angle, almost straight on inner border, dentate on outer ; border pale tawny orange narrowly edged in black. Under- side. Ground colour rather paler rufous chestnut, with paler rufous on outer border of wings. Silvery lines and bars as usual ; black marks in fore wing strong. Tails thin, 6 & 5 mm long. The FEMALE is still unknown. Holotype male. ZAMBIA : Shiwa Ngandu, [near Danger Hill, east side Upper Loangwe Valley], 2Q.xi.62 (C. B. Cottrell) in B.M.(N.H.).

REVISIONAL NOTES ON AFRICAN CHARAXES 247 Charaxes eudoxus ? subspecies, status uncertain Under this heading we have to consider specimens from the Sudan, one taken in the Imatong Mts in the Mongala Province and one from Bendi, south west of Yambio. There is also a specimen taken in the forests at Arua in north-western Uganda. Carpenter (1937) placed the two Sudan specimens as mechowi, but if this is correct they represent a very dry form of that race. They are characterized by the upper- side having brighter chestnut to the bases of the wings ; paler more extended rufous orange bar up to 6. In the hind wing the orange band is broad, the submarginal black bar much reduced, the upper portion not being more than 4 mm and the remainder of the spots below 5, well separated and decreasing in size. On the underside, it is interesting to note that the Imatong example is devoid of silvery lines and bars, thus analagous to the form nzoia of eudoxus amaurus but simulating lucretius to an even greater extent. It should be noted that amongst the dozens of mechowi I have examined, none are without silvery lines below. The specimen from Arua is fully marked with silver lines on the underside.

Macquart described this species from male and female specimens stated to be in Serville's collection. No type-material exists in the MNHN, Paris, and is considered to be lost. The BMNH, London, collection contains a male specimen in very bad condition from Bigot's collection which bears an identification label in Macquart writing which reads "Gymnostylia setosa , by present designation, TASMANIA: MNHN, Paris (No. 2305). Paralectotype : i Macq. n.sp. Tasm.", an accession label "3 47" and a rectangular white label "49" in faded ink. The condition of the specimen was bad when described, for Macquart stated in the original description that it was "en grande partie denuded"; it is now in dreadful condition, completely and thickly coated with fungus though structurally complete. Masicera simplex Macquart, 1847 : 87 (71). Holotype <$, TASMANIA: BMNH, London (ex coll. Bigot). The holotype bears Macquart's label "Masicera simplex. $ n.sp. Macq."; it is in fair condition, except for loss of both mid legs and left fore and hind legs, large hole in abdominal base and glue obscuring scutellum. Masicera tenuisetosa Macquart, 1848 : 206 (46). ? holotype or syntypes^, JAVA: not located, possibly lost. Macquart stated that this was described "De Java. Collection de M. Payen". I have been unable to locate the type-material of tenuisetosa and it is possibly lost. Masicera varipes Macquart, 1846 : 291 (163). Holotype <$, TASMANIA (Verreaux): MNHN, Paris (No. 2283). The holotype bears Macquart's label "Exorista varipes. , TASMANIA: MNHN, Paris (No. 2302). The holotype bears Macquart's label "Platytainia maculata. $. Macq. n.g., nov.sp. Tasm.", an accession label "3 47" and a rectangular white label reading "48."; it is in bad condition, head lost, left mid leg missing, body greasy. Townsend (1936 : 232, I939« : 373) also noted that the head of the holotype is lost. This fact makes it particularly difficult to place the genus Platytainia Macquart, of which maculata is type-species, and at present the genus is enigmatic. Polychaeta nigra Macquart, 1851 : 154 (181). Holotype $, TASMANIA: MNHN, Paris (No. 2269) . The holotype bears Macquart's label "Polychaeta nigra. $ Macq. n.g., n.sp. Tasm." and an accession label "3 47", and is in fair condition; much mould, head coated in grimy deposit, right mid leg lost, some thoracic bristling rubbed (Townsend, 1932 : 50, described the head as "covered with mycelia and grime"). Prosena dispar Macquart, 1851 : 203 (230). LECTOTYPE $, by present designation, 'TASMANIE' [probably in error for New South Wales]: MNHN, Paris (No. 2352). Paralectotype : i $, same data as lectotype (MNHN) . The lectotype bears Macquart's label "Prosena dispar. $. Macq. n.sp." and an accession label "4 46"; it is in fair condition, head slightly crushed, thorax dirty, scutum damaged, and left mid leg lost. The paralectotype $ also has the "4 46" accession label, and is probably correctly associated with the lectotype, although it differs slightly in abdominal colour and in colouring of the pleural and humeral hair. This is one of the species for which the stated provenance of Tasmania is suspect, and for which New South Wales is a more probable locality of origin. Prosena dorsalis Macquart, 1847 : 97 (81).

Unfortunately no female specimens of Rutiliini now exist from Bigot's collection (in BMNH, London) which fit with Macquart's description of R. setosa, nor are there any speci- mens labelled by Macquart as either setosa or testacea (although there are correctly identified males of the latter species from Bigot's collection in BMNH). It must be concluded that the type-material of R. setosa, which consisted of female syntypes, is lost. (The evidence that it consisted of syntypes comes from Macquart's statement under the heading R. testacea, following the original description of R. setosa, that "Nous croyons qu'elles [i.e. true testacea females] sont les femelles du R. Testacea, et que celles que nous avions conside're'es comme telles, et qui appartiennent a une espece nouvelle, a la setosa".) In the earlier Macquart (1846 : 305 (177)) work dealing with supposed females of R. testacea he appears to imply that the specimens are in Paris Museum, and the MNHN Macquart collection has therefore been checked for any specimens that could possibly be types of R. setosa (in case, for example, the statement of "M. Bigot" in the original description of setosa was an error for "Museum") ; however, there are no specimens in Paris that could be setosa types, which supports the conclusion above that the actual type-material is now lost. Rutilia subtustomentosa Macquart, 1851 : 191 (218). Holotype $, TASMANIA: MNHN, Paris (No. 2323). The holotype bears Macquart's label "Rutilia subtustomentosa <$. Macq. n.sp.", and an accession label "3 47", and is in perfect condition. It may be noted that the specific name is not hyphenated on Macquart's label, but was hyphenated in the original publication. Rutilia viridinigra Macquart, 1846 : 307 (179). LECTOTYPE , by present designation, TASMANIA: MNHN, Paris (No. 2318). Paralectotypes : i $, same data as lectotype (MNHN) ; i $, Tasmania or Australia (MNHN) ; i ?, 'Sydney' (BMNH, ex coll. Bigot). The lectotype bears Macquart's label "Rutilia viridinigra Macq. n.sp." and an accession label "13 44", and is in good condition except for loss of hind legs and some scutellar setae. One of the paralectotypes in MNHN has the same "13 44" accession reference as the lecto- type, but the other has an accession label "229 35". The $ paralectotype in BMNH from Bigot's collection is correctly associated with the lectotype, and bears an original Macquart label "Rutilia viridinigra $. Macq. n.sp" which is gummed to another label from Bigot's collection on which Bigot has added in his writing the words "Sydney" and "Nomm. par. Macq."; although in the original description Macquart only mentioned the locality "Tasmanie", this $ is nevertheless considered to be an original syntype because of the original Macquart label which it bears, and also because there is often doubt about the accuracy of Bigot's localities (the "Sydney" in his writing could be in error). Furthermore, as Macquart described the species from "plusieurs individus" it is possible that he did not record all the localities. The original Macquart label is accepted as con- clusive evidence that the Bigot specimen is an original one. Standing with the syntype series in MNHN, Paris, there is another $ specimen, but this has an accession label "4 46" and is not an original specimen; in the same collection there is a o* specimen with "4 46" accession reference, and this also is not part of the original material (it is probably the male which Macquart, 1851 : 192 (219) described later in the 4* Supplement) The BMNH collection contains one $ specimen received in exchange with Paris Museum in 1924 and bearing the "4 46" accession reference of that Museum; it has no type-status. Rutilia viriditestacea Macquart, 1851 : 190 (217). LECTOTYPE <$, by present designation, TASMANIA: MNHN, Paris (No. 2321). Paralectotype: i <$, same data as lectotype (MNHN). The lectotype bears Macquart's label "Rutilia viriditestacea. Macq. n.sp. $.", and an accession label "3 47", and is in very good condition (except for a few small holes in the thorax) . The paralectotype specimen is labelled "3 47" like the lectotype, but is incorrectly asso- ciated with the lectotype (having narrower frons, all dark thoracic hair, lacking bluish violet reflections) . R. W. CROSSKEY 291 Standing in MNHN collection with the syntype specimens there are two unlabelled and wrongly associated male specimens, which appear without doubt to have been added later to the collection; they have therefore no type-status. Rut Hi a vittata Macquart, 1855 : 126 (106). Holotype $, SOUTH AUSTRALIA ('colonie d' Adelaide') : BMNH, London (ex coll. Bigot). The holotype bears Macquart's label "Rutilia vittata $. Macq" and is in fair condition except for loss of both fore legs, right mid leg, and tips of hind tarsi, and damage to scutellum and right wing. Macquart's label lacks the usual "n.sp." inscription. The holotype of this species was incorporated into BMNH, London, collection in 1904, and has a printed label "Ex coll. Bigot. Pres. by G. H. Verrall, Oct. 1904." on which Austen has added "S.Australia." in pencil. Senostoma variegata Macquart, 1847 : 96 (80). Holotype ?, TASMANIA: BMNH, London (ex coll. Bigot). The holotype bears Macquart's label "Senostoma variegata. $ n.g., n.sp. Macq."; it is in very bad condition, both third antennal segments, both fore legs, right mid leg and left hind leg missing, body dirty and greasy, some chaetotaxy lost, hole in scutum and scutellar base. Townsend (1932 : 40, 1938 : 426) referred to a specimen, which I have not seen, in the Naturhistorisches Museum, Vienna, as being the female holotype from Tasmania of 5. variegata, and (in the 1932 paper) stated that it is labelled "variegata Macq. Type Bigot". This is almost certainly a label attached to a specimen by Brauer, and cannot signify the true type of Macquart, which (as shown above) bears Macquart's own label and is still correctly present among Bigot's material in BMNH, London. Brauer's meaning of the word "Type" is undoubtedly different from present usage, and it is quite certain that the specimen in Vienna recorded by Townsend is both wrongly identified and not a type of Senostoma variegata. S. variegata is type-species of Senostoma Macquart and Macquart's original label on the holotype bears the formula "n.g." as well as "n.sp.". For many years the generic name Senostoma was mis-applied to a genus of Rutiliini, but Senostoma although belonging in the subfamily Proseninae is not a Rutiliine, and Paramonov (1968 : 384) has recently and rightly drawn attention to this. Sumpigaster fasciatus Macquart, 1855 : 125 (105). Holotype <$, QUEENSLAND, Moreton Bay: BMNH, London (ex coll. Bigot). The holotype bears Macquart's label "Sumpigaster fasciatus <$. n.g., n.sp. Macq"; it is in extremely bad condition, body largely concealed (less so on abdomen) in mould, all legs lost except left hind leg, eyes partially collapsed, some chaetotaxy (including all scutellar bristles) lost. Macquart published the locality as "De 1'Oceanie. Moreton-Bay.". Tachina cilipes Macquart, 1843 : 219 (62). Holotype (J, EAST INDIES (Marc): MNHN, Paris (No. 672). The holotype bears an original label in Macquart's writing reading "No. 18 Tachina cilipes", and an accession label "1196 36"; it is in poor condition, head glued to thorax (but certainly correctly associated), body dirty, chaetotaxy of frons, mesonotum and scutellum rubbed off, right third antennal segment and the left fore and right mid legs missing. Tachina javana Macquart, 1851 : 177 (204). Holotype $, JAVA: BMNH, London (ex coll. Bigot). The holotype bears Macquart's label "Tachina javana , NEW GUINEA: BMNH, London (ex coll. Bigot). The holotype bears Bigot's label "D. maculifera. $.. Nouv. Guinee. J. Bigot" and a small rectangular white label with the printed word "N-GUIN" (i.e. New Guinea). It is in dreadful condition, all that remains being distorted head and thorax both completely concealed in thick mould, both fore legs and left mid leg (legs also mouldy) ; one wing also remains, this gummed to Bigot's name label. The holotype specimen was evidently in very bad condition when first described, as Bigot headed the Latin description with the word "Detrita", and the following French description with the word "De'teriore'". Doleschalla nigra Bigot, 1888 : 98. Holotype ?, MOLUCCA ISLANDS: BMNH, London (ex coll. Bigot). The holotype bears Bigot's label "D. Nigra. $. Moluques. J. Bigot" on which the generic name has been completed by the addition of "oleschalla" in an unknown handwriting; it is in fair condition, slightly mouldy, left fore leg and right fore tarsus lost, right mid and hind legs lost. The holotype of this species was incorporated into BMNH collection in 1904, and bears a printed label "Ex coll. Bigot. Pres. by G. H. Verrall, Oct. 1904." on which Austen has added "Molucca Is." in pencil. Doleschalla picta Bigot, 1888 : 99. LECTOTYPE ] from Ceylon in BMNH, London, ex coll.

Australia. J. Bigot."; it is in fair condition, except for loss of right mid leg, both hind tarsi and apices of fore tarsi. Although no other specimens are known which belong to this species, the general appearance of this Cylindromyiine resembles that of Gerocyptera Townsend species from the East Indian Archipelago and the western Pacific rather than an Australian species; the cited provenance of Australia is possibly, therefore, not quite correct. Rhynchiodexia tenuipes Bigot, 18850 : xi. Holotype $, NEW CALEDONIA: BMNH, London (ex coll. Bigot). The holotype does not bear any name label from Bigot's collection, but was incorporated into the BMNH collection in 1904, and bears a printed label reading "Ex coll. Bigot. Pres. by G.H.Verrall, Oct. 1904." on which Austen has added "New Caledonia, Oceania." in pencil. The condition is fair, except for loss of right mid and hind legs and of left hind tarsus, loss of tip of right wing, and partially collapsed eyes. Rutiliu argentifera Bigot, 1874 : 464.

E. KIMMINS SYNOPSIS Three hundred and five taxa are listed. Thirteen lectotypes are designated and the status of the other type-specimens is given. The present paper follows the general pattern of my previous lists of type-specimens in the British Museum (Natural History) but fewer lectotypes are designated in it. In 1960, I pub- lished a list of the Ephemeroptera types of species described by the three major British workers on the order, namely Eaton, McLachlan and Walker, in which lectotypes were designated where necessary. This list included species whose types were in museums other than in the BMNH. In the present list, in the references to taxa dealt with in Kimmins (1960), the status of the type- specimen is given in square brackets. In that paper, 72 lectotypes were designated from BMNH material, bringing the total designated up to 109 and thirteen more are designated in the present work. Three hundred and five taxa are dealt with in the present list, and of these, the type-specimens of 14 taxa (mostly described by Stephens) are either lost, or are unlabelled and not recognizable from Stephens' descriptions. Some were already lost or unrecognizable when Eaton was preparing his 1871 monograph. Additional information as to the locality data of the types, either not given or abbreviated in the original description, has been included here in square brackets. LECTOTYPE indicates present designation. This list was completed in March, 1970. aapta Harker (Mirawara), 1954 : 261-263, text-figs 69-71.

Six of these genera and eighteen of the species are here described as new, and many of the pre-existing nominal taxa are redescribed as they are not recognizable from their original descriptions. Also included are four new generic synonyms, fourteen new specific synonyms, and thirteen new combinations. The gall-forming habit is discussed and notes are given on the biology and morphological variation of most species. The phylogenetic relationships of this Australian group of genera are discussed, and the host-plant relationships are summarized in a table. The introduction includes short accounts of mounting methods and the morphological characters referred to in the keys. INTRODUCTION ACACIA and Eucalyptus are the two dominant plant genera of Australia. It is remarkable that although Eucalyptus is heavily attacked by insects there are no leaf-feeding Thysanoptera from any species of this genus, with the exception of the small polyphagous heliothripine Australothrips bicolor, although leaf-rolling Phlaeo- thripinae certainly occur on other Myrtaceae. On the other hand the genus Acacia, particularly the division Phyllodineae, supports numerous species of leaf-feeding Thysanoptera and a number of these have a gall-forming relationship with one or more host-species. The phyllodinous Acacia species, in which the usual Leguminous bipinnate leaf is replaced by a flattened expansion of the petiole called a phyllode, are almost entirely limited to Australia. It is not surprising therefore that the genera of thrips which attack these plants are found also only in Australia. However the author is not aware of any leaf-feeding Phlaeothripinae from any other Australian genus of 390 L. A. MOUND Legume. Apparently the evolution of these thrips has not been along lines of botanical affinity, but has involved the filling of a series of ecological niches. This is probably inevitable in a low rainfall area, where the number of available host- species which are perennial and have reasonably broad leaves is rather limited. Leaf-feeding and leaf-rolling Phlaeothripinae are common on mesophytic plants of the high rainfall areas of Eastern Australia where they form a complex of species and genera, related to Teuchothrips, which extends into the Indonesian region. In order to colonize the drier parts of Australia, thrips have had to adapt to Acacia species on more than one occasion, and this has given rise to a series of groups restricted to Acacia trees. The Phlaeothripinae which have colonized other plants of the low rainfall areas such as Casuarina, Geijera and Pittosporum are not closely related to the Acacia-living species. The insect order Thysanoptera is divided into two sub-orders, the Terebrantia in which the females have an ovipositor, and the Tubulifera in which there is no ovi- positor and the last abdominal segment is produced into a tube. Many of the genera of Terebrantia in Australia can be recognized by use of Priesner's key to the genera of the world (1949), although only one small family, the Aeolothripidae, has been studied systematically (Mound, 1967). However the genera of the Tubulifera, in which only one family, the Phlaeothripidae, is recognised, are much more difficult. This is because so few species have been described that the available genera are poorly defined, and moreover there are far too few genera available for the numerous species that can be found. There are two sub-families in the Phlaeothripidae, the Megathripinae which have broad band-like maxillary stylets and feed on fungal spores, and the Phlaeothripinae which have slender stylets and feed on the tissues of higher plants, or on fungal hyphae, or rarely on other Arthropods (see Stannard, 1968). The Australia/New Guinea region is rich in Megathripine species but these are less readily collected than the numerous species of the Phlaeothripinae. The present work is part of an attempt to provide a generic framework for the Australian Thysanoptera. The Phlaeothripine species living on Acacia trees have been treated separately because they are reasonably isolated systematically, probably on account of the ecological situation discussed above, and also because they are a major element in the thrips fauna over much of Australia. The genera discussed here fall mainly in the sub-tribe Kladothripina of the tribe Hoplothripini (Priesner, 1960), although the four species of Empresmothrips are of doubtful affinity. This sub-tribe is polyphyletic in the present author's opinion, and has been derived from leaf-feeding species of the Hoplothripina in the Teuchothrips [Liothrips complex of genera. Many of the species in this complex produce leaf-rolling galls e.g. Tolmeto- thrips, Eugynothrips, Eothrips, and in view of the morphological similarities it is reasonable to consider that the gall-forming Kladothripina have been derived from this stock. The author's views on the relationships of the various genera discussed in this paper are summarized in Text-figure i and referred to at length after each generic definition. GALL-FORMATION. The process of gall-formation on Acacia trees has been dis- cussed by Froggatt (1927) and more recently by the present author (Mound, 1970,6) GALL-FORMING THRIPS IN AUSTRALIA 391 but little is known of the very early development of a gall. Apparently an enation develops rapidly on a phyllode in response to an adult feeding on the surface. The adult remains within the hollow enation and is then sealed into it as the lips of the gall meet overhead. Eggs are then freely deposited over the inner surface of the gall, although K. rugosus lays its first eggs close up to the lips of the gall on A. pendula. In several species the inter-segmental membranes of the abdomen become greatly distended in ovipositing females and such individuals are apparently able to lay more than one hundred eggs. Eventually, possibly as a result of two or more generations, a gall with an internal diameter of less than one centimetre may contain several hundred adult thrips. Several Lepidoptera and Diptera live as inquilines in these galls, and all four species of Koptothrips are apparently inquilines. Csiro- thrips and Grypothrips species probably only enter galls that have been attacked and the contents destroyed by lepidopterous caterpillars. A list of the Acacia species from which thrips galls have been reported is given in Mound (19706), and a summary of the host records of Phlaeothripinae on Acacia trees is given below in Table II at the end of the descriptive text. Several Phlaeothripine species live in the mines of lepidopterous larvae in phyllodes, and both these and other species may be found breeding between pairs of tied phyllodes. MORPHOLOGICAL VARIATION. One of the most difficult problems in the present work has been the great range of variation shown by some species. The largest specimen of Grypothrips mantis for example is almost twice as long as the smallest, and this is accompanied by remarkable differences in body shape (Text-figs 18 & 19). Similar differences occur in Katothrips tityrus (Text-figs 23 & 24), whilst the differ- ences between micropterous and macropterous Oncothrips tepperi are very confusing. On the other hand Oncothrips rodwayi is a relatively stable species although the postocular setae may be present or absent for no apparent reason. These difficulties are reflected in the number of synonyms listed here for any given species, the present author having had the benefit of studying relatively extensive collections which frequently included the different forms of a species from the same gall or collecting site. ACKNOWLEDGEMENTS. Most of the material studied here was collected during a year's study leave from the British Museum (Natural History). Generous assistance was provided during this collecting tour by C.S.I.R.O. Division of Entomology, the Waite Institute, and the Queensland and Victoria Museums. Collections have also been made available by the Australian National Insect Collection (ANIC), CSIRO, Canberra; the California Academy of Sciences, San Francisco; the Queensland Museum, Brisbane; the Waite Agricultural Research Institute, Adelaide; the Naturhistoriska Riksmuseum, Stockholm; and Professor Dr H. Priesner of Linz, Austria. I am grateful to my assistant Mr B. R. Pitkin who drew most of the Text- figures, to Mr Arthur Smith who drew Text-figures 47-49 and 102, and also to Miss M. Steel who prepared most of the material for study and drew Text-figure i. TECHNIQUES. The material listed below under each species is mounted in balsam on microscope slides, although a number of specimens of the commoner gall-forming species remain in alchool. The author prefers to collect thrips into a low concentra- tion of alcohol (50-60%), or into AGA (60% alcohol-io parts; glycerine-i part; 392 L. A. MOUND acetic acid-i part), as these fluids cause most specimens to become distended and remain relaxed and soft. The AGA must be removed by washing for several hours in 60% alcohol, and black or very dark specimens may need to be bleached in cold 5% sodium hydroxide solution, although this damages the wings. Dehydration is best carried out through a progression of alcohols to absolute alcohol in the minimum effective time, and to facilitate this it is usually necessary to pierce the body in several places. Clove oil is a very convenient clearing agent before the specimens are placed in balsam as it tolerates small traces of water. Specimens mounted in one of the water-soluble mountants such as Berlese, Swanns or Hoyers are frequently inadequate for critical study. These media, particularly if preceded by caustic potash treatment, often cause antennal segments and the apices of some expanded setae to collapse. Water soluble mountants shrink to a greater extent than balsam as they dry and this often distorts the head shape due to pressure from the cover glass. TERMINOLOGY. Many of the characters used in the keys and descriptions below are based on recent work on the Thysanoptera, particularly L. J. Stannard (1957). The praepectus or praepectal plates are the anterior sclerites of the prosternum (not to be confused with the cervical sclerites), which are well developed in Csirothrips (Text-fig. 6) but are absent in Akainothrips (Text-fig. 2). The probasisternal plates are the posterior prosternal sclerites, which are greatly enlarged in some Lichano- K-ONYCHOTHMPS WARITHR/PS PANOPLOTHRIPS CARCINOTHKIPS •\ISHL-FOIIMINe OH CASU/IRIH* FIG. i. Inter-relationships of some Australian Phlaeothripine genera. GALL-FORMING THRIPS IN AUSTRALIA 393 thrips species (Text-fig. 65). The mesopraesternal plates are the anterior sclerites of the mesosternum, which are frequently reduced to two lateral triangles. Dupli- cated cilia of the fore wing occur in many genera on the distal posterior margin of the fore wing. The term 'pronotal shield' is used here to distinguish the dorsal sclerite of the pronotum, because 'pronotal width' is sometimes confused with the width across the fore coxae. The maxillary bridge is well known in the flower- and grass-living genus Haplothrips, it is a chitinous connection between the so-called maxillary guides which underlie the stylets and probably provide muscle attach- ments. It should be noted that in none of the genera treated here are the fore wings constricted medially as in the common flower-living Tubulifera of the genus Haplothrips, and in the gall-living species of Euoplothrips on Smilax.

Pelta reticulate, wider than long; tergites II-VI with two pairs of sigmoid wing-retaining setae, and anterolateral to these 2-4 pairs of accessory sigmoid setae; wing-retaining setae on VII reduced; tergite IX with BI and B2 shorter than tube in both sexes; terminal setae black, longer than tube; sternite VIII of $ mantis with large glandular area. Definition of this genus is complicated by the great range of size, and related variation in proportions, shown by the type-species mantis. The genus resembles the Kladothripina in the sense cone formula of the antennae and the armed fore tibiae and tarsi. However it does not appear to be on the same evolutionary line as the gall-forming Kladothrips or Oncothrips species, but is probably independantly derived from Teuchothrips-like ancestors. A similar long narrow head occurs in Sacothrips Moulton, 1968, but that genus has three or four sense cones on segment three, and four sense cones on segment four of the antennae. Lichanothrips, which is described below, has much broader fore wings and the maxillary stylets are very low in the head. The relationships of these genera are discussed under Lichanothrips. Grypothrips mantis lives in leaf-mines of Lepidoptera, but has also been found beneath the cuticle of split young stems and as a secondary species within galls on Acacia trees. It is possible that this cryptic habit foreshadows the gall-forming habit of other Kladothripina. Csirothrips, Warithrips and Dunatothrips may also have a similar relationship with Lepidoptera, but these genera can be distinguished by a well developed praepectus and the absence of fore wing duplicated cilia.

Adiaphorothrips is a synonjon of Machatothrips, a genus of the Megathripinae (Mound, 1970^ : 118), but Girault used the name for a wide range of Tubulifera with one or more pairs of cheek setae. The original description of clavisetae refers to four females and one male, although Girault subsequently used two of these specimens to describe Adiaphorothrips citritarsus, which is discussed above under the new genus Akainothrips. Of the remaining specimens on the type-slide, two are males of Grypothrips mantis, but the third specimen agrees with the description of clavisetae and is here designated as the LECTOTYPE female of that species. $ macropterous.

Males are rather smaller than females and also have a smaller size range, otherwise the two sexes are very similar. The largest and smallest females in a single series collected at Lake George, N. S. W. had body lengths of 4400^ and 3ioo(x, and head lengths of 55O[x and 420^. Moreover large body size is accompanied by hypertrophy of the fore femur, the fore tibial tubercles, the base of seta 62 on tergite nine, and also the genae on either side of the mouth cone. Text-figs 18-19 and the measure- ments given below are taken from the largest and smallest females of this species that have been seen. All the specimens from Canberra and Lake George have the seventh antennal segment dark, similar to the holotype from Lamington, Queensland. However, several specimens from near Parkes and Forbes, N.

Small to medium sized, pale or brown species of Phlaeothripinae. Head longer than broad, cheeks without major setae, weakly constricted behind eyes, parallel or weakly concave; postocular setae far behind eyes, or not developed; maxillary bridge present, although not always heavily sclerotized; mouth cone rather broadly rounded. Antennae on anterior margin of head or slightly ventral; antennal III with one sense cone which usually arises on ventral surface, IV with three (or two) sense cones; apex of VI broadly truncate, VII and VIII closely united. Pronotum wider than long, epimeral sutures complete; epimeral setae widely expanded, remaining major setae not developed except in tityrus; praepectal plates present or absent, mesopraesternum reduced to two lateral triangles; fore femora enlarged, fore tibia with an apical tubercle in three species; fore tarsus with a tooth in both sexes. Mesonotal midlateral setae small in tityrus, not developed in other species; metanotal setae small and acute. Fore wings, when present, parallel-sided, rather weak, without duplicated cilia except in duplex. Tergites II-VII with two pairs of wing-retaining setae, these are usually reduced on VII; BI and 62 on tergite IX short and expanded; sides of tube frequently convex, narrowed to apex, terminal setae fine and usually short; terminal aperture of tube constricted, occupying about one third of terminal diameter. Sternite VIII of male tityrus with transverse glandular area anterior to accessory setae. As is clear from the above definition, the species included in this new genus are rather diverse. The group probably represents the basal stock from which both Dactylothrips and Oncothrips have been derived. K. tityrus is the largest of the species included, and in some ways is the most specialized, whereas duplex can be regarded as the least specialized. All six species have the terminal aperture of the tube constricted as in Dactylothrips, and both duplex and brunneicorpus have indica- tions of the longitudinal sutures which are typical of the tergites of Dactylothrips. The species included in both these genera have a broadly rounded mouth cone, rather heavily sclerotized posterior abdominal segments, the praepectal plates either present or absent, a tendency for reduction of the major pronotal setae, and a tendency for the tube to be aberrant and non-tubular in shape. In Dactylothrips species the maxillary stylets are close together in the middle of the head, the antennae arise on the anterior margin of the head, and the fore wings lack duplicated cilia. In the first two of these characters Katothrips is more similar to Oncothrips, although in the latter genus the maxillary bridge is even less well sclerotized. The ventral position of the sense cone on the third antennal segment is most unusual, although there is a tendency in both Dactylothrips and Oncothrips for the antennal sense cones to be ventrolateral. The generic name is derived from the Greek kato, meaning beneath or below, and refers to the position of the sense cones. The species of Katothrips probably live in cryptic situations on Acacia trees such as in leaf-mines or tied leaves, or in galls. However, they are not primary gall 4io L. A. MOUND producers. Careful examination of such habitats in Australia, including Hymenop- tera and fungus galls, will undoubtedly produce more species.

Girault compared this species briefly with Kladothrips augonsaxxos. There is a single specimen in both the British Museum (Natural History) and the Victorian Museum, Melbourne which bear identical data to the holotype of tityrus, although these were labelled by R. Kelly as Kladothrips rodwayi. The unique holotype of differens is a very large hemimacropterous male, and the lectotype of acallurus is a large macropterous (dealate not apterous cf. Bagnall) female. A long series of this species from Lake George, N. S. W. has shown that the head is longer in oedymerous than in gynaecoid individuals, and moreover the head of the male is more constricted medially (Text-figs 23 & 24). Females occur as either macropterae or hemimacrop- terae although only hemimacropterous males are known. However the oedymerism is not related to the two wing lengths. This type of variation should be contrasted with that of Oncothrips tepperi in which wing length is continuously variable and is closely related to the degree of oedymerism. K. tityrus is very similar to brunneicorpus described below, but in that species the pronotal major setae are not differentiated from the discal setae except for the epimerals. The species does not produce galls but has been found in the galls of chalcid wasps, and in Lepidopterous leaf -mines and tied phyllodes on Acacia trees.

Paratype hemimacropterous female collected in same gall as holotype, in BMNH. The gall in which this species was collected was less than 5 mm deep.

GALL-FORMING THRIPS IN AUSTRALIA 417 This genus is an offshoot of the Teuchothrips complex of species which cause leaf- roll galls on a wide range of plants in Australia, e.g. Bursaria, Callistemon, Myoporum, Pittosporum, Stenocarpus. Kellyia can be distinguished from Teuchothrips by the rather elongate head with the maxillary stylets meeting medially, and the long third antennal segment. The genus was placed in the Kladothripina by Priesner (1960 : 293) but is better placed in the Hoplothripina with Teuchothrips and such leaf- rolling genera as Eugynothrips and Tolmetothrips. Kladothrips is undoubtedly derived from this group, with Oncothrips and Neocecidothrips standing in an inter- mediate position. The two species placed in this genus have both been collected from galls, although they are not gall-forming insects. They have been found breeding in the galls of hymenoptera, but it is not possible to know if they feed on plant tissue or on fungus or are predatory on some other inquiline such as a mite species.

Kladothrips Froggatt; Bagnall, 19296 : 194. Macropterous, bicoloured species of Phlaeothripinae causing galls on Acacia phyllodes. Head elongate, eyes large, cheeks usually narrowed to base; postocular setae small or absent; mouth cone short and rounded. Antennae eight-segmented, VII constricted at base, closely united with VIII; III with one sense cone, IV with three (or two) sense cones. Pronotal shield narrow, much longer than wide, epimeral sutures complete; major setae short and expanded, or absent (epimerals elongate in augonsaxxos) ; anteromarginal setae absent. Praepectus absent, sternal area of pronotum with large chitinous islets (7-10^ in diameter) ; mesopraesternum reduced or absent medially. Fore coxae and femora swollen; fore tibiae short and stout with a small apical tubercle on inner margin ; fore tarsal tooth large, length of tooth including tarsal width greater than length of tibia. Mesonotal lateral seta expanded, metanotal median setae small. Fore wing pale with two expanded sub-basal setae and 15-20 duplicated cilia. Pelta elongate triangular, reticulate; tergites with reticulate sculpture particularly laterally, II-VII with two pairs of sigmoid wing-retaining setae, these setae sometimes reduced on VII. Tergite IX with BI and Ba expanded, BS long and acute; tube shorter than head, sides evenly narrowed to apex, terminal setae dark. Sternites with about 20 accessory setae in two irregular transverse rows (one row in augonsaxxos) ; glandular area on sternite VIII of male present or absent. Intersegmental membranes of abdomen frequently grossly swollen in egg-laying females (Text- fig- 47)- The genus Kladothrips has never been formally denned but was published by Froggatt in a footnote to an article on Australian thrips. The brief notes in the footnote indicated that the antennae were seven-segmented, but after studying specimens collected by Froggatt, both Moulton (1927) and Bagnall (19296) corrected this statement. Bagnall gave Oncothrips Karny as a synonym of Kladothrips although these genera are here kept separate. Kladothrips froggatti Bagn. is here regarded as a synonym of rodwayi Hardy, and K. intermedius Bagn. as a synonym of tepperi Karny, and these two species are placed in Oncothrips. The species acallurus and different described by Bagnall in Kladothrips in 1932 are here regarded as synonyms of tityrus Girault and placed in the new genus Katothrips. The type specimens of Cladothrips [sic] punctatus Rayment, 1948 have been studied on loan from the Australian National Insect Collection, Canberra. This species is a member of the Megathripinae and is here regarded as a synonym of Phaulothrips fuscus Moulton, 1935, syn. n. As a result of the above changes only four species are now accepted in Kladothrips, one of which is here described as new and one is removed from Grypothrips. Three of these species, and probably all four, are primary gall producers on the phyllodes of four different species of Acacia trees. The genus includes the most highly specialized Phlaeothripinae associated with such galls, but is very closely related GALL-FORMING THRIPS IN AUSTRALIA 421 to Onychothrips. In particular K. augonsaxxos is intermediate between the two genera in such characters as the number of sense cones on the fourth antennal segment, the number of pronotal major setae, the shape of the head and probasisternal plates, and even the colour of the antennae. Onychothrips is dis- tinguished by not having the pronotal shield unusually elongate, or in more general terms, in having a less elongate body but a more elongate tube. Oncothrips, although related, has no tubercle on the fore tibia and the males have a well developed glandular area on sternite eight. In the British Museum (Natural History) collection there are five micropterous specimens collected by the author on Acacia, harpophylla. These apparently represent a further species of Kladothrips, but as their most remarkable characters are undoubtedly correlated with microptery, the species cannot be defined adequately until macropterae become available.

(Text-fig. 54) Grypothrips acaciae Moulton, 1968 : 109-110. The genus Grypothrips, which Moulton apparently only knew through Karny's description, can be distinguished by means of the generic key given above. The present species is a typical Kladothrips, closely related to the type-species of the 422 L. A. MOUND genus, rugosus, and the new species described below. The male differs from both these species however in having an irregularly circular glandular area on sternite VIII which is about 35 microns in diameter. Two specimens of acaciae were found in the Froggatt collection at Canberra bearing almost identical data to the holotype, and the author collected a single female with numerous larvae in a large bean-shaped phyllode gall on Acacia harpo- phylla. Similar galls on karpophytta have been collected at various times containing Koptothrips zelos, but the other species of Koptothrips are all known to be inquilines, not gall-producing species. In view of this it is probable that acaciae is the true gall-former on harpophylla, and K. zelos an inquiline. The galls in which these thrips have been taken are the largest thrips-induced galls from Acacia species. Up to two inches in length they are shaped like tubular bean- or pea-pods and the evaginated portion of the phyllode is usually reddish in colour. Measurements (in microns) of male. Body length 3300.

A . doratoxylon is classified in the Section of Acacia known as the Juliflorae which have the flower heads elongate, not globular as in typical Mimosa blossoms. It is interesting that the host-plant of Onychothrips, A . aneura, is also placed in the Juliflorae although the host-plants of the other three Kladothrips species are placed in the Section Plurinerves.

The phyllode galls from which these specimens were taken looked like flat kidney- shaped pods, and the specific epithet ellobus is derived from the fact that the specimens were found 'in a pod'. These 'pods' were about 2 cm in diameter and 3 mm thick, and could be mistaken quite readily for the true pods of the Acacia tree. Kladothrips rugosus Froggatt (Text-figs 44, 47-49 & 57) Kladothrips rugosus Froggatt, 1906 : ion. Kladothrips rugosus Froggatt; Bagnall, 19296 : 194-195. The maxillary stylets of rugosus are deeply retracted into the head as in the two species of Onychothrips but unlike the other species of Kladothrips. However, in GALL-FORMING THRIPS IN AUSTRALIA 425 49 FIGS 48-49. Kladothrips rugosus: 48, head, pronotum and fore leg of female. 49, fore wing. 426 L. A. MOUND the extreme reduction of the major setae and the very pale antennae rugosus appears to be the most highly evolved of the Kladothrips group. The abdominal inter- segmental membranes of many females of this species are greatly hypertrophied as Froggatt (1927 : 87) has figured for augonsaxxos (Text-fig. 47). The galls formed by rugosus on A . pendula are flask-shaped when fully developed, distinctly wider at the base than at the point of evagination from the phyllode, about 2 cm deep and 1-5 cm wide. In many galls there was a tendancy for the eggs to be laid near or in the apex of the 'flask' close to the mouth of the gall. Also dead adults were observed frequently squashed between the opposing surfaces of the mouth of the gall. It is possible that galls develop more slowly on pendula than on other species of Acacia, and this allows adults to enter and leave the developing evagination. Most of the young galls of this species which were examined contained both male and female thrips. Froggatt refers to, and illustrates, heavily rugose galls in the original description of rugosus. Such galls were occasionally seen by the present author on A. pendula but they are apparently aberrant, the surface being attacked by some unidentified insect. Normal healthy galls caused by rugosus are quite smooth with the typical glaucous green of their host plant. The female here selected as LECTOTYPE was found dry on a card in Froggatt's collection at Canberra. It appears to have come from the original collection on which the species was based as it was labelled in Froggatt's handwriting and was accompanied by the dry rugose galls shown in the original figure. $ bicoloured brown and yellow; brown on head and antennal I, prothorax, fore femur, anterior and lateral margins of pterothorax, mid and hind legs, and abdominal segments II-X; yellow on pelta, pterothorax, fore tarsi, fore tibiae and apex of fore femora, antennals II-VIII (Bagnall's description refers to the less mature specimens which are coloured as in ellobus above) .

The unique female on which this species is here described was thought at first to be a gynaecoid specimen of one of the other Oncothrips species. However it differs from rodwayi in having short major setae on tergite nine, from antennatus in having reduced pronotal setae, from tepperi in the position of the maxillary stylets in the head, and from all three of these species in the greater length of the terminal setae relative to the tube. Moreover it is unlikely that the holotype is gynaecoid in view of the long and slender fore tarsal tooth. Oncothrips rodwayi (Hardy) comb. n.

Kladothrips rodwayi Hardy; Bagnall, 19296 : 194-195. As Bagnall pointed out, the original description of this species is remarkably confusing. Hardy states 'antennae generally very pale yellow, sometimes black'. This statement may be due to the fact that the three syntypes mounted on a slide by Hardy and now deposited in the Australian Museum, Sydney were strongly bleached with caustic potash. There are four normal syntypes in Dr H. Priesner's collection in Linz, Austria. Girault's statement that the head of tithonus is longer than that of rodwayi may be due to the fact that the Hardy syntypes are crushed, making the head appear relatively short and broad. The type-slide of tithonus bears three females and one of these has the postocular seta on one side elongate. The seta on the other side of the head, and the postocular setae of the other specimens are all short. Bagnall's (1929 : 197) record of intermedium (—tepperi} from Gippsland with Koptothrips flavicornis is a misidentification of rodwayi. This species causes galls on the phyllodes of Acacia melanoxylon, and it probably has the same geographical range as this tree, i.e. Tasmania and the South Eastern Highlands and coastal regions from Adelaide to the New South Wales/Queensland border. The galls are purse-shaped, like a large cockroach ootheca, about i cm long and 75 mm deep. In an attempt to establish at what time of the year these galls are produced Mrs H. V. Andre wartha collected at monthly intervals from February until June 1968 on a tree near Adelaide. However the author could not find any differences in the contents of these galls from samples collected in October and November 1967. On each collecting date galls were found containing males, females and larvae. No oedymerous or short winged forms have been found of rodwayi, although one dwarf male was collected near Adelaide. This dwarf male has seta 63 on tergite 444 L. A. MOUND nine expanded at the apex instead of acute as is normal in this genus. The post- ocular setae are variable in their development in each of the series studied. Usually the postocular setae are no longer than the other head setae, but a few specimens have one or both postoculars well developed and expanded, 10-13^ long. The pelta, with its sinuous lateral margins (Text-fig. 73) is quite distinctive in this species. Measurements (in microns) of one $ from near Adelaide. Body length 2650.

The single female from Gippsland, Victoria collected with Koptothrips flavicornis and referred to by Bagnall as intermedius is here regarded as a specimen of rodwayi. The types of intermedius are fully expanded, macerated and crushed, whereas the two syntypes of tepperi in Bagnall's collection are not only rather small, they are GALL-FORMING THRIPS IN AUSTRALIA 445 both strongly telescoped. This difference in the preparation of the specimens accounts for most of the differences between the nominal species. The data on the slides of intermedium may not be correct. It is possible that the specimens were collected at some distance inland, where the host plant Acacia oswaldi lives, and merely posted to Bagnall from Melbourne. This type of error is not uncommon with some of the early records from Australia. The nominal species Brithothrips fuscus was based on four females and one 'male', although the latter specimen has recently been shown to be a female (Mound, 19706). The fore tarsal teeth are broken off in the holotype and the three paratypes labelled as females. The author has recently suggested that this damage happened when the specimens were being put on to slides, but several further specimens have now been studied which were taken in the field by the author with broken fore tarsal teeth. The holotype of fuscus is an oedymerous, dealate (probably hemimacro- pterous) female, and the 'allotype' is a normally developed female. The pattern of variation in this species is extremely confusing and an account of the variants found within a single gall has recently been given under the name fuscus (Mound, 19706). Most specimens that have been studied are fully macro- pterous, but populations have been found in which individuals vary from micro- pterous to fully macropterous. This continuous variation in wing length is unusual in Thysanoptera, most species occurring as invariable morphs, e.g. micropterae or hemimacropterae. In 0. tepperi the degree of wing development is correlated with allometric growth of other parts of the body. The micropterous specimens are always oedymerous with greatly enlarged pronotum and fore legs, and foreshortened antennae and head. Males are rather smaller than females with a less well developed fore tarsal tooth, but both sexes can show varying degrees of wing reduction and oedymerism, and also varying degrees of body size. Two small micropterous females collected by the author near Gilgandra, N. S. W. are particularly interesting as they both have seta 63 on tergite nine expanded at the apex instead of acute. The body length of these specimens is about 1900^, and the apex of this seta may possibly be correlated with very small body size. The same character is noted above on a dwarf male of rodwayi. Small individuals of tepperi have the pronotal major setae very much smaller than large individuals. 0. tepperi has been collected by the author at several localities on Acacia oswaldi. The galls on this plant are very similar to the galls produced by rodwayi on A. melanoxylon. These two species of Oncothrips are closely related and it seems likely that the two host-plants are also related to each other. However tepperi is unusual in the Australian gall forming thrips in being polyphagous, a habit which is possibly related to its morphological variability. An insect species in which the physiology is sufficiently labile to allow a range of morphological variants to coexist is also likely to have a physiology able to accept more than one host plant. 0. tepperi was originally described from A. sclerophylla, and the author has collected specimens from a gall on an herbarium specimen of A. homalophylla in the CSIRO Herbarium at Canberra. Two related species of Cosmopterygid moths (det. I. Common) were bred from galls of tepperi on oswaldi from Loxton S.A. and Peak Hill, N. S. W., but there was no indication as to how the caterpillars originally entered the galls. 446 L. A. MOUND Measurements (in microns) of one macropterous $ with one micropterous $ in parentheses.

GALL-FORMING THRIPS IN AUSTRALIA 449 The size variation in this species is very great, and the relative lengths of some setae do not remain constant throughout this size range. In large specimens the setae on tergite nine are about half as long as the tube, whereas in small specimens these setae are barely one-third as long as the tube. Similarly the head is shorter than the pronotum in large specimens but much longer than the pronotum in small ones. The variation of the fore tibial tubercles is particularly interesting as it is apparently weakly negatively heterogonic. The smallest females have a larger tubercle on the tibia than the largest females. The holotype has been chosen from a series of rather large individuals. 0. arotrum produces apparently identical galls to tepperi Uzel, and the two species have been collected at at least one site on the same tree. These galls are spherical with an external diameter of about 15 mm. The walls of a gall are sometimes about 2 mm thick, and they become very hard as they mature. One gall with an internal diameter of about 10 mm contained 750 adults and at least 500 immature stages. In most of the galls studied the males formed about 10% of the adult population, whereas in tepperi Uzel the sexes were commonly found in equal numbers. On several occasions females of arotrum were found with the abdominal intersegmental membranes distended, but never as much as in Kladothrips species. The second instar larvae of arotrum have long slender and acute prothoracic setae, whereas in tepperi these setae are shorter with a clearly rounded apex.

Syn. n. Onychothrips hakeae Bagnall; Mound, 1968 : 142. The lengths of the head, pronotum and abdominal setae of the type-series of hakeae fall within the range of variation of tepperi collected in galls on Acacia aneura. The original labels of the hakeae series, which were written by W. W. Froggatt, state Thrips from galls on Hakea or Grevillea foliage'. Moreover in Froggatt's collection there are several specimens of tepperi bearing the data 'N.S.W. Cobar, Hakea galls, 1910 (Solomon)'. These records of Hakea or Grevillea as a host plant for this insect require further substantiation because Australian xerophytic plants are difficult to identify in the absence of flowers or fruit. Hakea and Grevillea have a great range of leaf form, and several species look quite similar to Acacia species. Unfortunately thrips tend to attack the less healthy plants, and as a result it can be difficult to find a tree which bears both galls and flowers and fruit. The galls of tepperi cannot be distinguished from those of arotrum, and the two species have been collected from the same tree. The author's host records for this species are all given as A . aneura, but it is possible that one or other of the Onycho- thrips species occurs on Acacia brachystachia as well. These two species of Acacia are not easy to separate. Notes on the sex ratio of tepperi and the recognition of the larvae are given above under arotrum. 450 L. A. MOUND 9 macropterous.

Rhopalothripoides Bagnall; Mound, 1968 : 148-149. Froggattothrips was based on four individuals with a remarkably short broad out- line. It is now realized that this shape is the result of telescoping of the body seg- ments due to starvation prior to death. The genus has recently been redefined and at present includes only a single species. This is probably not related to the two American genera found on Cactus species, Rhopalothrips and Scopaeothrips. These two genera both have highly specialized cuticular sculpture and they are probably more closely related to the Idiothrips group, of which there are several species in Australia living at ground level. The New Caledonian species Scopaeothrips inter- medius Bianchi has not been studied but it may be congeneric with froggatti. Rhopalothripoides is here regarded as an offshoot of the Australian Kladothrips group, but its relationships will be more easily studied if macropterous individuals can be found.

The above synonymy is the result partly of the imperfect mounts on which the nominal species were based, and partly of the great range of size found in this species. The males are particularly variable, the holotype of froggatti being a very small gynaecoid male. In the gynaecoids the pronotum is short, but in oedymerous specimens it is as long as or longer than the head. All the specimens which have been studied lack ocelli and wing-retaining setae, and have the pterothorax and pelta short and broad as is typical of apterous individuals. However, a short wing membrane is developed, about 5O[j. long, which bears one or more broadly expanded setae. Axillary sclerites cannot be dis- tinguished, however. In most micropterous thrips it is usual for axillary sclerites and ocelli to develop before wing rudiments appear. It is remarkable that this species whose skeletal structure is so typically 'apterous' should possess a rudi- mentary wing membrane. This species was originally collected in the leaf-glands of Acacia dealbata and A. decunens. The present author has found it in abundance inside the leaf-glands of A. parramattensis. These glands, or domatia, are pits of doubtful function which occur on the adaxial surface of the rhachis of Acacia leaves between the bases of each pair of pinnae. The external aperture of one of these pits is usually about one millimetre in diameter, but the cavity is ovoid and may be three millimetres long and two millimetres across. Up to twenty eggs of froggatti have been seen inside one gland, and although usually only a single female, or a male and a female, were found inside each cavity, on one occasion the author observed three adults and one larva.

This species can be distinguished from Thaumatothrips by the presence of prae- pectal plates, and the absence of fore wing duplicated cilia and pronotal antero- marginal setae. The unique holotype is damaged and has probably been remounted from a dry card. The pronotal midlateral setae are apparently absent. The post- ocular setae are not as strongly expanded as the original figure indicates (40-47 p. long, 3(j. at apex), and the inner dorsal seta of the fore femur is acute at the apex. The cheek setae are weaker than in the other species of Warithrips except for the basal pair, and the species can be recognized by the armature of the fore femur and the large ventral seta (B3) on tergite nine.

Sternites II-VIII with at least six pairs of marginal setae, these form long combs in female but are less conspicuous in male; numerous accessory setae distributed across sternites; sternite VIII of male without glandular area; navicula of male genitalia with a long acute apex. This genus is apparently unique in the Thysanoptera in the form of the terminal setae of the tube and the remarkable comb-like arrangement of the sternal marginal setae of the females. The broad wings with relatively few duplicated cilia, the maxillary stylets low in the head, and the form of the mesonotum, the metanotum and the last two antennal segments are all similarities to Lichanothrips described above. However, the simple slender legs and the well developed mesopraesternum suggest that Xaniothrips is unrelated. Sacothrips Moulton, 1968, has a similar long head with a pair of stout basal setae, but the fore tarsal tooth is well developed, the tube very long and the setae on tergite nine short. It is not possible at present to relate this new genus to any known form, nor to place it in a suitable tribe. The generic name is derived from the Greek word xanion — a carding comb, in reference to the comb-like setae of the female. The two new species described in this new genus were collected by the author on a group of four young trees of Acacia harpophylla. They were living between green tied phyllodes, and as the individuals were highly active, pairs of tied phyllodes were picked from the trees and placed in a large plastic bag. At the time of collec- tion it was assumed that only one dominant species was present, but later study 458 L. A. MOUND showed that there were seven species, including Xaniothrips xantes, X. leukandros, Lichanothrips albus, L. pulchra and L. magnificus. As a result of the collecting method it was not possible to know what species were associated with each other between any one pair of phyllodes, but the two Xaniothrips were the dominant species and of these xantes was the most abundant. There was no evidence that the FIGS 96-101. 96-97. Warithrips maelzeri: 96, antenna. 97, tube and terminal setae. 98-101.

GALL-FORMING THRIPS IN AUSTRALIA 459 phyllodes were tied together by Lepidopterous larvae, but instead, where two phyllodes were in contact there was a thin film of a sticky white substance. In the opinion of the author these phyllodes were stuck together by a secretion produced by a thrips species, and as the Xaniothrips were the most abundant it is possible that they were the originators of this complex association of species. The external surface of the phyllodes was tinged with a red colour, as also was noted on the surface of thrips-induced phyllode galls on A. harpophylla.
