NOVITATES ZOOLOGICAE Vol. XXVH. JUNE 1920. No. I. SUPPLEMENTAL NOTES TO MR. CHARLES OBERTHUR'S FAUNE DES LEPIDOPTERES BE LA BARBARIE, WITH LISTS OF THE SPECIMENS IN THE TRING MUSEUM. {Continued from Vol. XXIV. p. 409 (1917).) By Lord Rothschild, F.R.S., Ph.D. (Plates XIV— XVII.) THE long-expected volume of Mr. Oberthiir's Etudes de Lepidopterologie Comparee, containing the Noctuidae of Algeria, has at last appeared. The date on the wrapper is Octobre 1918, but the volume was only, received in March 1919, so the date of publication for the new names published therein must be taken as 1919. It calls for various remarks. Mr. Oberthiir has adopted Guenee's system of classification of the Noctuidae. Now, although the aim of Science is to establish uniformity of nomenclature and a single classificatory system, it is impossible to forbid the use of any system ; we can only regret, therefore, that such a renowned entomologist as Mr. Oberthiir adopts systems and methods abandoned by the majority of modern workers in Entomology. But while we can only regret this retrograde policy of Mr. Oberthiir, we can and must strongly deprecate the reasons he has and gives for not adopting Sir George Hampson's classification. Whatever other objections Mr. Oberthiir may have to the British Museum classifica- tion, he lays stress on one only, namely he harps upon the rather unfortunate error made by Sir George Hampson in placing Phragmatobia breveti 0 berth, in the genus Maenas. This error has long ago been acknowledged by its author. Mr. Oberthiir makes great capital out of the aquatic habits of certain American species of Maenas as opposed to the desert habitat of bzeveti, quite ignoring the fact that the genus Maenas contains many African and Indo-Malayan species as well as American, and these are, as far as we know, non-aquatic in their habits. Sir George Hampson was misled by the somewhat aberrant neuration of P. breveti, which is almost identical with that of Maenas ; moreover, breveti is not a Tricho- soma as Mr. Oberthiir asserts, but a true Phragmatobia, The abortive wings of the $ are not a generic character, but only specific, as can be seen in the case of Cymbalophora rivularis Men., which has a 9 with abortive wings, while Cymba- lophora pudica Esp. and C. oertzeni Led. have the $ full winged. The aquatic habits of the larva are also only of secondary importance, for in the genus Spilosoma (Diacrisia) we find Spilosoma (Diacrisia) metalhana with a free swimming aquatic larva, while sannio and amurensis, which are very closely allied, 1 2 NOVITATES ZOOLOGICAE XXVII. 1920. have ordinary terrestrial larvae. We cannot condemn a whole system simply because its author made one rather striking error. I have adopted the British Museum classification because so far there does not appear to be a better one. According to this classification, the family Noctuidae is divided into fifteen subfamilies, viz. : Agrotinae ; Hadeninae ; Cuculliinae ; Zenobiinae (Acronyctinae) ; Era- striinae ; Phlogophorinae (Euteliinae) ; Odontoninae (Stictopterinae) ; Sarrothri- pinae ; W ' ester manniinae (Acontiinae) ; Catocalinae ; Diphterinae (Mominae) ; Phytometrinae ; Noctuituie ; Polypogoniiiae (Hypeninae) ; and Hyblaeinae , Of these fifteen subfamilies, two, namely, the Diphterinae and Hyblaeinael have no representatives in Algeria, and three others, the Phologophorinae, Odontoninae, and Sarrothripinae, have only one representative each. Sir George Hanipson, who is a great stickler for classical correctness, in the case of names forming subfamily appellations in which the ending is in "ia,'' insists on the subfamily being formed with the ending " ianae," such as Cucullianaehom Cucullia. The International Rules, however, say the sub-family term is to be made by the addition of the ending " inae " to the word, and so I have made the families Cuculliinae, Zenobiinae, Erastriinae, and W estermanniinat end in " iinae " instead " ianae." I am taking the species, in the first place, in the order Mr. Oberthiir has placed them in, for the purpose of critical remarks where these may be necessary ; but at the end I am giving a full list of the species and genera in the order followed by the British Museum classification. I am giving a list of the Algerian, Tunisian, and Moroccan specimens in the British Museum as well as those at Tring. 1. Bryophila petrea Guen. Bryophila petrea Guenee, Hint. Nat. Ins. Spec. Gen. Lipid, vol. v. Noct. vol. i. p. 25. No. 22 (1852) (Andalusia). Mr. Oberthiir records this species from Maafa and Lambessa ; we have received 35 from Guelt-ea-Stel, 1 from Batna, and 1 El Kantara. There are in the Tring Museum 18 (J <$, 17$$ from Guelt-es-Stel. This series shows considerable variation in the forewings, some being pale grey with hardly any markings, while others are of a deeper brighter grey with conspicuous black markings, and a few have such dark grey forewings that the black markings show up hardly darker than the ground colour. 1 ^Environs de Batna, 1914 (A. Nelva) ; 1 cj El Kantara, August 1917 (V. Faroult). 2. Bryophila aerumna Culot. Bryophila aerumna Culot, Xoct. et Gtom. d'Eur. pt. i. vol. i. p. 131, pi. 22. f. 17 (1912) (Giryville). Monsieur Culot quotes this and a number of other new species as "Oberth." because he adopts the names suggested by Mr. Oberthiir in his letters to him ; while Mr. Oberthiir quotes them as "Culot (secundum Oberthiir)." Both these methods are wrong ; the correct way of quoting is Bryophila aerumna Culot ; but if it is thought desirable to mention Mr. Oberthur's connection with these species, it should be done as follows: Bryophila aerumna Culot (Oberth. in lilt.) NOVITATES ZOOLOGICAE XXVII. 1920. 3 There are at Tring 32 specimens of this species from Sidi-bel- Abbes, September 1917 (M. Rotrou) ; Sebdou, September 1918 (P. Rotrou) ; Perregaux, September 1915 (V. Faroult) ; AIn Draham, September 1911 (V. Faroult). [Bryophila aeton Culot = Catamecia mauretanica Stdgr. Calamecia jordana var. mauretanica Staudinger and Rebel, Cat. Lepid. Pal. Faun, pt. i. p. 213. No 2192i) (1901) (Biskra). Bryophila aeton Culot, Noct. el Gtom. d'Eur. pt. i. vol. i. p. 132. pi. 22. f. 16 (1912) (El Outaya). Neither Mr. Oberthiir nor Mr. Culot have perceived that the type of aeton is only a heavily marked fine specimen of Catamecia mauretanica Stdgr.] 3. Bryophila divisa oxybiensis Mill. Bryophila oxybiensis Milliere, Rev. Zool. 1874, p. 242 (Cannes). Catamecia bryophiloides Rothschild, Novit. Zool. vol. xxi. p. 330. No. 194 (1914) (Guelt-es-Stel). The name divisa has one year's priority over that of pomula ; Esper being 1791, while Borkhausen is 1792. Pere Engramelle, it is true, is older, but he has " La Pomule " not pomula, so the date of pomula is that of Borkhausen, who latinised Pere Engramelle's name. In 1913 (Novit. Zool. vol. xx. p. 125, No. 52) I unfortunately identified some unicolorous grey specimens of this insect from the Oued Nca as Bryophila pineti Stdgr., which I then only knew from a drawing. I have now discovered this error, and I name these unicolorous specimens ab. unicolor ab. nov. The form of divisa oxybiensis most similar in coloration to typical divisa must bear the name ab. rufilincta Rothsch. (Novit. Zool. vol. xx. p. 125 (1913)), and the form with the basal two-thirds of the forewing below median fold black is ab. distincta Rothsch., and, lastly, the very dark form ab. saturatior Rothsch., both described on p. 125. We have at Tring 1 Hammam R'hira June 1916, 1 Alger January 1914 (V. Faroult) ; 27 c?c?, 21 $$ Oued Kca, June 1912 (E. H. and C. H.) ; 5 9 (1827). Both Warren's ab. pallida and my Borolia lacteicolor are the pale form of this insect. It is strange that this pale form is almost invariably smaller than the darker more strongly marked typical form. The series of Mauretanian examples at Tring consists of 319 specimens, 218 typical vitellina and 101 ab. pallida Warr. from Environs d'Alger, May 1908 (W. R., E. H., and K.

Mr. Oberthiir quotes Engramelle as the author, but Ernst and Engramelle when describing species not yet described only gave French names to their insects, and therefore they are quite inadmissible as authors, and the names given to their species by Hiibner and others must be quoted under their respective authors. As, however, that part of Hiibner containing his saucia was published in 1827 and Haworth's margaritosa in 1809, this latter name must be used for the present species. Although fairly widespread in Mauretania, it is much rarer than the last. We have 86 specimens from Ai'n Draham, August — September 1911 (V. Faroult) ; Oued Hamidou, June 1912 (V.

D. m. tscherskii (p. 908) is exceedingly close to kamtschaticus, only the wings are generally (not always) shorter, and the bills less powerful and often shorter. The lateral tail-feathers of tscherskii have also, as a rule, more black than in kamtschaticus, but sometimes appear not to be different in this respect. Woodpeckers are, of course, only occasional visitors on Bering Island, where there are no forests, so that it cannot be a real Woodpecker home. 119. Alauda arvensis pekinensis Swinh.

LESSER REDPOLL. Carduelis linaria cabaret (P. L. S. Mull.). B. of Berks, and Bucks, p. 110. Vict. Hist, of Bucks, p. 137. Winter visitor, but also breeds locally in small numbers. Kennedy only records this species as a winter visitor from about the end of November onwards, and never very common. Hartert on several occasions has noted small flocks in autumn and winter, and there are several specimens in the Tring Museum from Aston Clinton, near Tring, caught in October and November. Twenty-eight years ago Lord Rothschild observed it several times on the "flats" near Champneys Park in summer, and Grossman has recorded breeding on Berkhamsted Common, close to the Bucks, boundary. C. Oldham {in litl.) states that he has seen a few pairs every summer about the Herts .-Bucks, boundary near Berkhamsted, and adds that he also saw one at Mentmore on June 15, 1913, " uttering its trilling song in flight." The only part of the county where breeding is known with certainty to have taken place is the Thames Valley between Shiplake and Wraysbury. Many scattered pairs used to haunt the various " rod beds " by the river, nesting in most cases on the Berks, side, and sometimes several nests might be found within quite a small area. The late Major F. W. Proctor found many nests in this district between 1905 and 1914; not only in willows, but also in thorns, furze bushes, and small trees at some little distance from the river. Mr. E. E. Pettitt gives details (in Hit.) of half a dozen Bucks, nests found by him in the same district between 1909 and 1916, but adds that after the severe winter of 1916-17 none were met with. 20 (27).

In the old manuscript at Din ton Hall is an excellent figure of "ye Crossbill or Shellapple" which was shot there in 1782, with the following notes : " Is an inconstant visitor of this island and breeds in ye pine-forests of Germany and Switzerland ; it feeds on ye cones of those trees. It is a fact that it changes ye shades of its colour in different seasons of ye year from deep red to yellow and ye females which are greenish alter to different varieties of the same colour. Ten of these birds were shot and several others seen by ye Revnd W. Goodall in ye Wilderness of Dinton Hall August 8th' 1791. They had been observed by the servants some weeks, tho' they mistook them for bull finches. Q>T had they bred there ? As some of ye males had not then gained their full j^lumage and one of ye females had not as yet a single yellow feather." It is, of course, well known now that the red plumage is that of the adult male, though peculiar ideas about the plumages of Crossbills prevail occasionally even now. Kennedy records occurrences at Drayton (about 1847), and also at Fulmer, Risborough, and Burnham Beeches, and mentions a hen bird seen near Eton in November 1867. More recently T. Marshall recorded this species in the Wycombe district in 1898 (Field, December 3, 1898, p. 897) ; while in December 1909 a flock of about thirty was seen at Fawley Court (H. Noble, Brit. Birds (mag.), vol. iii. p. 303). In March 1910 six were seen at Drayton Beauchamp (C. Oldham, i.e. p. 409), and several at Langley about the same time (H. Noble). A pair killed at Dinton, January 15, 1910, is in the County Museum (Edw. Hollis). The only definite record of breeding is that by Mr. R. Bulstrode (Brit. Birds (mag.), vol. vi. p. 60), who saw a flock of four or five birds near Gerrards Cross on March 27, 1910, and was shown a nest on April 1 which then contained four eggs. The young were still in the nest on April 23. 23 (37). CHAFFINCH. Fringilla coelebs coelebs L. B. of Berks, and Bucks, p. 31. Vict. Hist, of Bucks, p. 136. Resident, but numbers apparently augmented by immigrants in winter. Very common in all wooded parts of the county. Mr. A. Mayall found eight eggs in a nest near Burnham, from which six young were reared, in May 1919 (Brit. Birds, vol. xiii. p. 80). 24 (38). BRAMBLING. Fringilla montiMngilla L. B. of Berks, and Bucks, p. 106. Vict. Hist, of Bucks, p. 136. Winter visitor, sometimes in great numbers. The Brambling appears every winter, and has been observed from October to April, but generally between November and March. Numbers vary greatly, sometimes not many are observed, while in other years they are very numerous ; Hartert does not think that this depends on the severity of the winter — at least not in this country — but more on the amount of beech mast. From time to time 180 NOVITATES ZOOLOGICAE XXVII. 1920. enormous flights are observed. An influx of this kind took place in the winter of 1905-6, when the beech woods of the Chilterns swarmed with these birds, flocks of several hundreds being repeatedly seen. Considerable numbers were also present during the mild winter of 1919-20. 25 (40). HOUSE-SPARROW. Passer domesticus domesticus (L.). B. of Berks, and Bucks, p. 33. Vict. Hist, of Bucks, p. 136. Common resident. By far the most numerous of all birds in the county. One of the most obnoxious habits of this species is that of dispossessing the House-Martins of their homes. Sir. A. H. Cocks adduces some evidence that the Martins occasionally retaliate by killing the nestling Sparrows, but further evidence on the point is desirable (cf. Zool. 191G, p. 358). 26 (41). TREE-SPARROW. Passer montanus montanus (L.). B. of Berks, and Bucks, p. 32. Vict. Hist, of Bucks, p. 136. " A resident species, but noichere numerous and very local." The above words of Kennedy are still correct and well describe the status of this bird in Bucks. Kennedy reports a nest near Buckingham in a Sand- Martin's hole. He also mentions specimens killed near Datchet and Slough. From autumn to spring, however, Tree-Sparrows are common in the neighbour- hood of Wendover, Aston Clinton, Ivinghoe, where Oldham regularly observes them, usually feeding with House-Sparrows and Finches in farm-yards and stack- yards, and near Cheddington, but they are seldom seen in the summer. Mr. Oldham observed one near Cheddington May 10, 1908. Hartert has seen it near Aylesbury and Ovington. In the Thames Valley there are scattered colonies, which nest in the pollarded willows by the river-side, especially in the Maidenhead and Bray districts. Mr. Pettitt mentions a small colony at Horton. 27 (42). CORN-BUNTING. Emberiza calandra calandra L. B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 137. Resident, Not actually rare in the arable districts, but nowhere numerous, and not often noticed in winter. Kennedy (I.e.) says " it congregates in large numbers late in the autumn and is gregarious until the return of the spring." We have never seen large flocks in Bucks, or Herts. In the Thames Valley Mr. Pettitt notes it as breeding near Taplow, Slough, and the reservoirs on the Middlesex border. F. A. Monckton has recorded a case in which the song was heard in November near Eton {Field, November 14, 1908, p. 888). 28 (43). YELLOW BUNTING, or YELLOWHAMMER. Emberiza citaneUa citrinella L. B. of Berks, and Bucks, p. 30. Vict. Hist, of Bucks, p. 18. Resident. A common bird, but somewhat diminished in numbers since 1917. Mr. A. H. Cocks records a nest built in the side of a straw-rick, about 3 ft. 7 in. from the NOV1TATES ZOOLOGICAE XXVII. 1020. 181 ground at Skirmett (Zool. 1916, p. 352), but this is not a very infrequent occurrence. 29 (47). CIRL-BUNTING. Emberiza cirlus cirlus L. B. of Berks, and Bucks, p. 176. Vict. Hist, of Bucks, p. 138. Resident. The Cirl-Bunting breeds regularly in the Chiltern Hills district and neigh- bourhood. In winter it strays about, but apparently not usually very far from its breeding-grounds. The following are the localities from which we have evidence : Terriers End, near Tring (Chas. Oldham, evidently nesting) ; neigh- bourhood of Wendover (Hubert D. Astley, Oldham, Witherby, Hartert, nesting) ; Ashley Green, south of Berkhamsted, Coombe Hill, Chequers Court (Hubert I>. Astley, nesting) ; Drayton Beauchamp (4 . vi . 1864, nest found by H. H. Crewe, Field, 3 . xii. 1864, p. 384) ; Halton (skins of winter birds, eggs seen) ; Pitstone (caught in winter, H. H. Crewe) ; Ivinghoe (seen in winter, Hartert) ; downs between Princes Risborough and Wendover common, five males singing between Kimble and Wendover 4.vii.l910 (Chas. Oldham). In the Thames Valley it is of infrequent occurrence, but has been met with occasionally near Great Marlow. Mr. A. H. Cocks records one from Harleyford on January 26, 1884 (in lift.). The winter of 1917 has greatly diminished the number of Cirl-Buntings ; near Tring we have not heard or seen them since. 30 (53). REED-BUNTING. Emberiza schoeniclus schoeniclus L. B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 138. Resident, but breeding birds wander about in autumn. Not rare in suitable places on rivers and reservoirs. Breeds on the Tring and Halton Reservoirs, on the banks of the Thames, Colne, Chess, and Ouse, and in Stowe Park. In winter in small flocks, which haunt stack-yards and high- roads. Mr. E. E. Pettitt found a nest of this species in June 1905 at Wraysbury, which was placed in the crown of a pollarded willow ! He has also on two occasions met with Cuckoos' eggs in Reed-Buntings' nests in the county, both in 1908, in the Colne Valley. A very remarkable clutch of four eggs, pale blue without any markings, was taken by James Street at Mars worth Reservoir on May 9, 1910, and is now in the Tring Museum. 31 (56). SNOW-BUNTING. Plectrophenax nivalis (L.). Vict. Hist, of Bucks, p. 138. Winter visitor. Of somewhat rare and irregular occurrence in winter. The MS. in Dinton Hall mentions its occurrence there on January 8, 1776. Flocks have repeatedly been seen near Aston Clinton, and in 1895 near the Tring Reservoirs. On November 4, 1901, a male was shot at Drayton Lodge, Bucks., between Aston Clinton and Tring, by Mr. Henry Jenney. (February 22, 1894, another male was caught near Tring, between Tring and Aston Clinton, just in Herts.) Mr. C. H. Enison met with two on Ivinghoe Beacon on November 7, 1903 (Field, November 14, 1903, p. 844). 182 NOTITATES ZOOLOOICAE XXVII. 1920. 32 (61). WOODLARK. Lullula arborea arborea (L.). B. of Berks, and Bucks, p. 29. Vict. Hist, of Bucks, p. 139. Probably resident. Local and scarce. Observed in spring and summer near Fulmer, Beacons- field, Princes Risborough, Halton, and Chequers Court. 33 (62). SKYLARK. Alauda arvensis arvensis L. B. of Berks, and Bucks, p. 27. Vict. Hist, of Bucks, p. 139. Resident. Common on fields and meadows, from autumn to spring in flocks, which are probably partly composed of continental visitors. Breeds freely both in corn and grass land. An entirely buff- yellow variety was shot in December 1863 at Weston Turville (R. Tyrer, Zool. 1864, p. 8957). Such varieties are not rare and have been observed in many other places in England and elsewhere. 34 (67). TREE PIPIT. Anthus trivialis trivialis (L.). B. of Berks, and Bucks, p. 8G. Vict. Hist, of Bucks, p. 134. Summer resident. Not rare in wooded districts from April to September, but far from numerous in the Thames Valley, where, however, a few pairs may be found breeding in the Burnham and Taplow districts. 35 (68). MEADOW PIPIT. Anthus pratensis (L.) B. of Berks, and Bucks, p. 27. Vict. Hist, of Bucks, p. 134. Resident and winter visitor. Nests in lowland pastures : on the canal banks near the Tring Reservoirs, Halton, Aylesbury, Buckingham, Castlethorpe, Farnham Common, Burnham Beeches, and, according to Kennedy, near Eton. In winter and during migration periods in small flocks near the Reservoirs. In the Thames Valley it is best known as a winter visitor, only a few pairs remaining to breed. 36 (74). BLUE-HEADED WAGTAIL. Motacilla flava flava L. Once observed. " In a pasture bordering one of the reservoirs near Tring, on April 29, 1917, my sister-in-law detected a Wagtail differing in colour from the Ray's Wagtails with which it was consorting. As we looked down from the top of the reservoir embankment on the birds running to and fro in the short grass, it was an easy matter to distinguish the stranger by its blue-grey crown and nape, the con- spicuous whitish-buff superciliary stripe, the less distinct streak of the same colour through the ear-coverts, and the buff wing-bars. The upper parts and ear-coverts were greyish-brown, the breast and belly pale yellowish-buff passing into bright sulphur- yellow on the under tail-coverts. I cannot say positively to which subspecies of Motacilla flava the bird (a hen) belonged, but the blue- grey crown and the pale ear-coverts point to M. f. flava, the subspecies, apart from Novitates Zooloqicae XXVII. 1920. 183 M. j. rayi, most likely to occur" (Chas. Oldham, Brit. B. vol. xi. p. 20, 1917). There is also a female in the County Museum, found dying near Aylesbury, June 2, 1911 (Edwin Hollis, in litt.). 37 (79). YELLOW or RAY'S WAGTAIL. Motacilia flava rayi(Bp.). B. of Berks, and Bucks, p. 85 (not 58). Vict. Hist, of Bucks, p. 134. Summer resident. Not a common bird, but more frequent in low-lying meadow land and in the neighbourhood of rivers, such as the Thames and Ouse. 38 (80). GREY WAGTAIL. Motacilia cinerea cinerea Tunst, B. of Berks, and Bucks, p. 26. Vict. Hist, of Bucks, p. 134. A breeding species in very small numbers in the Chess Valley, otherwise winter visitor, not common. The first mention of the breeding of this species in Bucks by John Gould occurs in Jardine's Contr. to Ornith. 1849, p. 137, and is repeated in his Birds of Great Britain, vol. iii. p. 49 (1873), where he states that for many years he has been aware of the breeding of the Grey Wagtail in the Chess Valley, and that when the Duke of Bedford " favoured him with a day's fishing," he found the nest on a wall of Mrs. Dodd's beautiful garden, where it always nested. Another pair also bred at Latimer, but in this case he did not find the nest. R. B. Sharpe, in his articles on the " Birds of Cookham," (Quart. Mag. High Wycombe Nat. Hist. Soc. vol. ii. p. 49, 1869), alludes to Gould's discovery of this nest in- a rose bush against the wall, and the fact of the male bird being found on the four eggs. He also says that another pair bred at Elliot's Mill, two and a half miles up stream. Clark Kennedy (I.e.) was apparently unaware of Gould's observations, but says that a few have been procured on the Thames in summer, though it is better known there as a frequent winter visitor. Bryant Burgess, however, informed him that it bred annually on the banks of the Chess. Hartert did not meet with it at Latimer in 1902, but more recent observations by the Duchess of Bedford and Mr. W. Bickerton show that it still frequents its old haunts at Chenies. near Sarrat Mill, some distance below Latimer, where, however, it was not found in 1918, while no observation took place in 1919.* To other parts of the county it is only known as a winter visitor. Mr. C. Oldham states that it frequents the reservoirs, canals, and water-cress beds of North Bucks in small numbers regularly from early September to mid-March. The Rev. H. D. Astley has recorded it from Chequers Court, and it is met with every winter in the Thames Valley. 39 (81). PIED WAGTAIL. Motacilia alba lugubris Temm. B. of Berks, and Bucks, p. 26. Vict. Hist, of Bucks, p. 134. Resident, but a good many move southwards in the autumn and return in early spring. A common bird, and widely distributed. * The breeding-place near Sarrat Mill, close to Chenies, is just a stone's throw or so outside Bucks., in Herts., while Latimer and Chenies are well within the Bucks, boundary. 184 N0Y1TATES ZOOLOGICAL XXVII. 1920. 40 (82). WHITE WAGTAIL. Motacilla alba alba L. B. of Berks, and Bucks, p. 134. Rare on passage ; has apparently once bred. On June 17, 1902, Hartert and Arthur Goodson went along the River Chess, near Latimer, in search of the Grey Wagtail. They failed to find the latter, but saw a pair of Wagtails feeding young which seemed to have quite grey backs, and which they took to be M. alba alba. A few hundred yards away they observed M. alba Ittgubris. On subsequent visits later in the year and in 1903 and l!iii4 Hartert failed to see any grey-backed birds. Recently Mr. Chas. Oldham has observed the White Wagtail in spring, though not nesting. On May 5, 1912, he saw one on Wilstone Reservoir ; on May 4, 1913, one with a party of the Yellow (Ray's) Wagtails at Startops End Reservoir ; and on May 3 and 10, 1914, a single one on Wilstone Reservoir. 41 (83). BRITISH TREE CREEPER. Certhia familiaris brittanica Ridgw. B. of Berks, and Bucks, p. 49. Viet. Hist, of Bucks, p. 133. Resident. Used not to be rare, but has greatly diminished in number since the severe winter of 1917. 42 (86). BRITISH NUTHATCH. Sitta europaea britannica Hart. B. of Berks, and Bucks, p. 50. Vict. Hist, of Bucks, p. 133. Resident. Not uncommon in well-timbered parts of the comity, particularly in Burnharn Beeches and Ashridge Park, but somewhat local and not very numerous any- where. 43 (88). BRITISH GREAT TIT. Parus major newtoni Prazak. B. of Berks, and Bucks, p. 23. Vict. Hist, of Bucks, p. 133. Resident. Generally the commonest of our Titmice. Though greatly reduced in 1917, increasing again rapidly in numbers. 44 (90). BRITISH BLUE TIT. Parus caeruleus obscurus Prazak. B. of Berks, and Bucks, p. 24. Vict. Hist, of Bucks, p. 133. Resident. Common, and apparently in many places scarcely less numerous than the ' Great Tit. 45 (92). BRITISH COAL-TIT. Parus ater britannicus Sharpe & Dress. B. of Berks, and Bucks, p. 24. Vict. Hist, of Bucks, p. 133. Resident. Fairly common in woods, parks, orchards, and gardens, especially where conifers are grown. Though the species suffered greatly during the severe cold of 1917, it is already increasing remarkably. Novitates Zoolooicae XXVII. 1920. 185 46 (97). BRITISH MARSH-TIT. Parus palustris dresseri Stejn. B. of Berks, and Bucks, p. 25. Vict. Hist, of Bucks, p. 133. Resident. Used to be fairly common, but has become much rarer since the severe frost of 1917. It is, however, increasing again in numbers. 47 (98). BRITISH WILLOW-TIT. Parus atricapillus kleinschmidti Hellm. The only record for Bucks of which we are aware is a male, formerly in the collection of H. H. Slater (now in the Tring Museum), shot by him at " Chersley, Bucks, 9.xi.l882.'' It was, of course, labelled by the collector as "Parus palustris," as at that time it was not yet distinguished, but is undoubtedly the present form. 48 (101). BRITISH LONG-TAILED TITMOUSE. Aegithalos caudatus roseus (Blyth). B. of Berks, and Bucks, p. 25. Vict. Hist, of Bucks, p. 133. Resident. Used to be found in practically all suitable localities, but suffered greatly during the severe frost of 1917. Near the Tring Reservoirs it bred year after year, but has been exterminated in that neighbourhood and not yet seen again. Prior to 1917 it used also to nest fairly commonly at Burnham Beeches, Ditton Park, etc., but has disappeared almost entirely from that district (E. E. Pettitt). As it is beginning to recover its former status in Berks., it will probably reappear in these localities before long. 49 (103). BRITISH GOLDCREST. Regulus regulus anglorum Hart. B. of Berks, and Bucks, p. 23. Vict. Hist, of Bucks, p. 132. Resident. Used to be fairly common in suitable localities, but has suffered greatly by the severe frost of 1917, and is now a rare bird. On July 28, 1918, Chas. Oldham heard one singing in the shrubbery at Aston Clinton Park, and another in the park at Ashridge on January 18, 1919 — the only two he has come across since the winter of 1916-17. Hartert has only seen a few near Tring, but not yet in Bucks., since 1917. In the south of the county it was formerly not uncommon, breeding in the Thames Valley at many points, but is only just beginning to reappear in small numbers. 50 (104). FIRECREST. Regulus ignicapillus ignicapillus (Temm.). B. of Berks, and Bucks, p. 173. Vict. Hist, of Bucks, p. 132. Exceptional winter visitor. Mr. Alfred Heneage Cocks informed us in 1902 of a specimen killed by his gardener, in his and his brother's presence, at Great Marlow in the sixties, about 1863. It was mounted and is in Mr. Cocks's possession, but it was only identified as a Fireerest some years after. According to Kennedy (I.e.), two Firecrests were procured near Eton about 1 865. This record is rather vague, and as soon after it is stated that a nest with 1S6 N0V1TATES ZOOLOGICAE XXVII. 1920. young, and the two parents, were brought to a Mr. Hasell in 1863, from Windsor Park, and the latter statement cannot be credited, the Eton record can hardly be accepted without caution. In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, it is stated that one was shot in January 1887, presumably at the Reservoirs. This statement, said to have been made on the authority of the then Hon. Walter Rothschild, is evidently erroneous, as all the supposed author remembers is a verbal statement made to him by the late Rev. H. H. Crewe that it had occurred in Ashridge Park. 51 (105). BEARDED TITMOUSE. Panurus biarmicus biarmicus (L.). B. of Berks, and Bucks, p. 174. Exceptional vagrant — one old record. On December 21, 1848, a pair, male and female, were shot on Wilstone Reservoir by the Rev. James Williams, of Tring Park. Only these two specimens were observed, and there is no other record of the occurrence of this species {Zoologist, 1849, p. 2418.) (About twenty years ago some specimens imported from Holland were released on Wilstone Reservoirs, but they disappeared.) 52 (107). GREAT GREY SHRDSE. Lanius excubitor excubitor L. B. of Berks, and Bucks, p. 168. Vict. Hist, of Backs, p. 134. Irregular and rare winter visitor. On January 8, 177S, one was shot near Dinton Hall. A female was shot near Wendover about the middle of November 1854, and a male on November 4 of the same year near Weston Turville (H. H. Crewe, Zoologist, 1865, p. 9416). In the winter of 1859-60 a specimen was shot on the banks of the Thames near Clewer, Berks. According to Kennedy (I.e.), a male was shot in 1862 near the Almshouses at Stoke, another in the winter 1865-66 on the banks of the Thames near Windsor, a third at Hampden (no date) which was in Bryant Burgess's collection. Mr. A. H. Cocks also reports one shot close to Great Marlow, either in the eighties or early in the nineties. Hartert saw one in October 1895 near Halton. A female was shot by the present Lord Rothschild on the " Flats " close to the Bucks, boundary near Cholesbury, 17.x. 1895; a male by a keeper near Long Marston, also close to the boundary, 1 8 . xi . 1 896 ; another female caught in a Sparrow-trap at Wilstone Reservoir, 2 . ii. 1 916. 53 (112). RED-BACKED SHRIKE. Lanius collurio collurio L. B. of Berks, and Bucks, p. 72. Vict. Hist, of Bucks, p. 134. Summer resident. Rather local and less common during the last twelve years or more than it used to be. In Kennedy's time it was common near Eton. Hubert D. Astley found it not rare near Chequers Court ; and Hartert has observed it there and near Wendover, Aston Clinton, Aylesbury, Buckingham, Dinton, Newport Pagnell, Castlethorpe, Wingrave, and Aston Abbots, but has not seen it recently near Wendover and Aston Clinton in places where it always used to be in evidence. Near the Reservoirs only about one pair has nested recentty. In the Thames Valley it is rather local, but Mr. Pettitt reports a few pairs breeding near Colne- brook, Horton, and Little Marlow. NOVTTATES ZOOLOOICAE XXVII. 1920. 187 54 (113). WAXWING. Bombycilla garralus (L.). B. of Berks, and Bucks, p. 174. Vict. Hist, of Bucks, p. 135. Irregular and rare winter visitor. Kennedy (I.e.) writes : " An immense flock appeared along the eastern shores of our island in the winter of 1849-50, which was very severe, and several speci- mens were at that time procured in different parishes of Buckinghamshire. I am indebted to the Rev. Bryant Burgess for the notice of a Bohemian Waxwing which was killed at Ivinghoe Aston in January 1850, and which is now in his collection. An immense number of Bohemian Waxwings were shot in the neigh- bourhood of Buckingham during the spring of 1867, as Mr. J. W. Thorpe told me." [In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, in a list of birds supposed to have occurred on the Reservoirs, it is stated that a Waxwing was " obtained in March 1883." Unfortunately this statement, made on the authority of the Hon. Walter Rothschild, cannot now be verified, as we cannot trace the specimen. In the Vict. Hist, of Herts, p. 201, it is said that " the first Hertfordshire specimen of the Waxwing was shot about a mile from Tring on the Aylesbury road, about 1851." As the Bucks boundary is very little more than a mile from Tring, this may almost be regarded as a Bucks record.] 55 (114). SPOTTED FLYCATCHER. Muscicapa striate striate (Pall.). B. of Berks, and Bucks, p. 74. Vicl. Hist, of Bucks, p. 135. Summer resident. Common everywhere in parks, large old gardens, and certain woods. The blue unspotted type of egg has been found near Slough (H. H. Vyse, Zool. 1890, p. 352, and Field, August 16, 1890, p. 250). 56 (116). PIED FLYCATCHER. Muscicapa hypoleuca hypoleuca (Pall.). B. of Berks, and Bucks, p. 169. Vict. Hist, of Bucks, p. 135. Probably occasional summer resident. The records for Bucks, are very few. According to Morris one was killed " many years ago " in the county, in the south-east, not far from Uxbridge. H. J. Elwes informed Kennedy of a well-authenticated nest taken near Eton in the summer of 1860. Mr. Heatley Noble, in litt. : "A nest with six eggs was taken on my late father's property, Berry Hill, Taplow, in June, 187- (the exact year cannot be given). The female was unfortunately killed on the nest." Mr. H. Heneage Cocks, in litt., says : " On May 12, 1883, our gardener at Great Marlow saw in our orchard a bird with white on the wings, which, from its move- ments and other habits, must have been a Flycatcher. He said it looked some- what like a female Chaffinch, but the beak was different. Sir J. A. Godley, K.C.B., reported several years before having seen one specimen there. Two days afterwards the gardener saw evidently the pair, but though I watched for them repeatedly I did not see them, nor were they ever seen again." On May 10, 1901, Hartert heard the song and observed a male in the park of Mentmore. In June of the same year he found no trace of these birds, nor ever afterwards. Mr. Edwin Hollis, while fishing at Hartwell, August 22, 1919, saw a male Pied Flycatcher. It was quite clearly recognized, as it sat within 8 or 10 feet of the observer for several minutes. 188 NOVITATES ZOOLOGKAE XXVII. 1020. 57 (119). CHIPFCHAFF. Phylloscopus collybita collybita (Vieill.). B. of Berks, and Bucks, p. 85. Vict. Hist, of Bucks, p. 132. Summer resident and autumn migrant. Common in all suitable localities. From February 10 to 18 a Chiffchaff frequented some willows on Wilstone Reservoir. (See Brit. B. vol. vi. p. 313.) In the Thames Valley it is generally distributed, and Mr. Pettitt notes it as especially numerous in Ditton Park. 58 (122). WILLOW- WARBLER. Phylloscopus trochilus trocbilus (L.). B. of Berks, and Bucks, p. 84. Vict. Hist, of Bucks, p. 132. Summer resident ami passage migrant. Generally distributed and hardly absent from any suitable localities. 59 (125). WOOD- WREN or WOOD- WARBLER. Phylloscopus sibilate sibilatrix (Bechst.). B. of Berks, and Bucks, p. 84. Vict. Hist, of Bucks, p. 132. Summer resident. The Wood-Wren occurs from April to September in beech and oak woods, in the Chilterns and near Brickhill. In the Thames Valley it is decidedly scarce and entirely absent from the greater part of the district. Mr. Grossman, however, states that it was formerly fairly plentiful in Burnham Beeches and in the woods between that place and Ashley Green ; but Mr. Pettitt has failed to meet with it breeding. A few pairs, however, haunt the woods near the western boundary where the county is more hilly. [SAVI'S WARBLER. Locustella luscinioides luscinioides (Savi). B. of Berks, and Bucks p. 172. In the Zoologist, 1867, p. 704, Lord Clifton published a note saying that he believed that he had observed a Savi's Warbler in a low hedge near Eton, but his description of the bird he saw is by no means convincing ; in fact the statement cannot be accepted. As is well known, the species was formerly a summer resident in Norfolk, Cambridgeshire, and Huntingdon, but, except for a single bird obtained on Fair Isle (!) in 1908, has not been proved to occur since 1856. Another rather vague record appeared in Saunders' Manual Brit. B. ed. ii. p. 92 (1899), as follows : " There is some evidence that this species was noticed in May 1897, in the Humber district, as well as near Olney, Bucks. ': The latter statement refers to an observation by Mr. C. J. Wilson, M.B.O.U., who kindly wrote to Hartert that he is fully convinced that the " Savi's Warbler is a just record," because he was close to the bird for some minutes, and the locality, the appearance, and the note of the bird were all in favour of its being L. luscinioides.] 60 (133). GRASSHOPPER- WARBLER. Locustella naevia naevia (Bodd.). B. of Berks and Bucks p. 78. Vict. Hist, of Bucks, p. 132. Summer resident. Rather rare. The only certain localities we know of are : on the foot of the hills east of Halton (heard and seen by Arthur Goodson and Ernst Hartert), NOTITATES ZOOLOGICAE XXVII. 1920. 189 Aylesbury (eggs seen by Hartert), Mentmore (heard by Hartert), Castlethorpe (observed by the late Lionel Wiglesworth), Farnham Common (observed by Alan Crossman), Chesham and High Wycombe (teste Kennedy), Drayton Beauchamp (Kennedy, probably from information of Harpur Crewe). In the Thames Valley it is a rare visitor, but Mr. E. E. Pettitt discovered a nest with five eggs at Hythe End in May 1894. Breeding also took place there in 1904, as well as at Wrays- bury in 1919. Mr. Pettitt notes the arrival of this species in the county on April 22, 1895, April 19, 1900, April 21, 1905, and April 30, 1910. In 1919 a pair nested close to Marsworth Reservoir, and the nest was found by Mrs. Oliver Pike, and some beautiful photographs taken by her busband. Mr. Pike is convinced that there were two pairs, but only one nest was found. The Grasshopper- Warbler had not occurred in this place during the last twenty-five years or more. 61 (136). REED-WARBLER. Acrocephalus scirpaceus scirpaceus (Herm.). B. of Berks, and Bucks, p. 80. Vict. Hist, of Bucks, p. 132. Summer- resident. Very common on the Marsworth, Wilstone, and Halton (Weston Turville) Reservoirs, and also on the Rivers Thames, Colne, Chess, and Ouse, wherever reeds abound. On the Tring Reservoir the Reed- Warbler is the usual and apparently only foster-parent of the Cuckoo, and all Cuckoo's eggs found there for the last twenty-five years are of much the same type, of course with some variations. Along the Thames and Colne Valleys it breeds commonly, as well as on the pond at Burnham Beeches. Mr. Pettitt has on two occasions found two Cuckoo's eggs in a Reed- War bier's nest in Bucks. For a note on unusually early nesting of this species at the Tring Reservoirs, see Brit. Birds (mag.), vol. ix. p. 48. 62 (137). MARSH- WARBLER. Acrocephalus palustris (Bechst.). Bred in 1909. (In Trans. Herts. Nat. Hist. Soc. vol. v. p. 76, it was stated, on the authority of the Hon. Walter Rothschild, that a Marsh-Warbler was shot near the Mars- worth Reservoir in August 1883, and was in the Tring Park collection. This statement seems to be due to an error in identification of a young Reed- Warbler.) At the time of the publication of the Vict. Hist, of Bucks, this species had not been ascertained to breed in the county. In 19C9 Mr. G. W. Kerr, who had previously discovered the Marsh- Warbler breeding in Surrey, was fortunate in discovering a nest with two eggs of this species, and also one of the Cuckoo in a dense nettle- bed not far from Magna Charta Island on June 1 4. The nest was about 12 yards from the river on firm ground, woven round two nettle stems, and about 18 in. from the ground in the parish of Wraysbury. (The locality in Surrey where the nest was foimd in 1907 is only a few miles south of the county boundary, and about five miles distant from where the birds were found breeding in 1909.) Subsequently Mr. E. E. Pettitt found a second nest at Wraysbury in the same nettle- bed, containing four Marsh- Warbler's eggs and one of the Cuckoo, on June 30, 1909, but the Cuckoo's egg was of a different type to that found on June 14 (Zool. 1909, p. 397). 190 NOV1TATES ZOOLOGICAE XXVII. 1920. 63 (139). SEDGE-WARBLER. Acrocephalus schoenobaenus (L.). B. of Berks, and Bucks, p. 78. Vict. Hist, of Bucks, p. 132. Summer resident. The Sedge-Warbler is generally distributed in the valleys, in the neighbour- hood of rivers, ditches, reservoirs and ponds, sometimes in thickly over-grown hedgerows quite a distance from water. Yarrell states that a single specimen was observed near High W^conibe in winter, without giving full date. Such a state- ment is hardly acceptable without proof, but curiously enough there are other statements of the occurrence of Sedge- Warblers in winter. 64 (145). GARDEN- WARBLER. Sylvia borin (Bodd.). B. of Berks, and Bucks, p. 82. Vict. Hist, of Bucks, p. 131. Summer resident. In similar places to the Blackcap, but far less common. Grossman and Hartert have observed it near Chesham, Beaconsfield, Burnham Beeches, Halton, Aylesbury, Buckingham, Mentmore, Ashridge Park, Castlethorpe, and Newport Pagnell ; but it occurs doubtless in many other places. In the Thames Valley it breeds in suitable spots, but in far smaller numbers than the Blackcap. Mr. E. E. Pettitt found a nest in Ditton Park which contained a young Cuckoo about four days old on June 5, 1906. 65 (146). BLACKCAP. Sylvia atricapilla atricapilla (L.). B. of Berks and Bucks, p. 82. Vict. Hist, of Bucks, p. 131. Summer resident. Common in parks, woods with undergrowth, gardens and spinneys. Gener- ally arrives end or middle of April, but Hartert. has heard it in full song on April 10, near Wilstone Reservoir. 66 (147). WHITETHROAT. Sylvia communis communis Lath. B. of Berks, and Bucks, p. 83. Vict. Hist, of Bucks, p. 131. Summer resident. Common in suitable localities, such as hedgerows, commons, edges of woods, and some gardens. 67 (148). LESSER WHITETHROAT. Sylvia curruca curruca (L.). B. of Berks and Bucks, p. 83. Vict. Hist, of Bucks, p. 131. Summer resident. The Lesser Whitethroat is generally less numerous than the Whitethroat, but not a rare bird. It is curious that it should be so much more plentiful in Middlesex than in the adjoining parts of Bucks. 68 (155). FIELDFARE. Turdus pilaris L. B. of Berks, and Bucks, p. 105. Vict. Hist, of Bucks, p. 130. Winter visitor. Arrives usually in October or even November, but there are records by Lord Rothschild and others for September ; getting scarcer from end of March, and Novitates Zoolooicae XXVII. 1920. 191 usually leaving before the end of April, but Crossman mentions ( Vict. Hist. Herts. p. 196) some seen at Great Gaddesden, on the boundary of Herts, and Bucks., on May 8, 1887. 69 (156). MISTLE-THRUSH. Turdus viscivorus viscivorus L. B. of Berks, and Bucks, p. 12. Vict. Hist, of Bucks, p. 129. Resident. Common in woods and parks over the greater part of the county, but not in any great numbers in the Thames Valley. 70 (157). BRITISH SONG-THRUSH. Turdus philomelos clarkei Hart. B. of Berks, and Bucks, p. 13. Vict. Hist, of Bucks, p. 129. Common resident. The British Song-Thrush is even more numerous than the Blackbird, and stays in Bucks, throughout the year, but a fair number pass through in the autumn, and some in the spring, evidently from higher ground in the north of England and Scotland. We have not been able to detect a specimen of the Continental Song- Thrush among them. The number of Song-Thrushes diminished very greatly in the severe winter of 1917, and though they have increased again considerably in numbers, they are still far behind their strength of before 1917. In the Newton collection at Cambridge is a clutch of four eggs of this species, taken near Stoke in May 1861, in which the ground-colour is perfectly white, with the usual markings. They were at first recorded as eggs of the Golden Oriole. See Ootheca Wolleyana, vol. ii. p. 288, and Field, May 25, 1861, p. 451. 71 (159). REDWING. Turdus musicus L. 1758. [Turdus iliacus L. 1766, of most authors.] B. of Berks, and Bucks, p. 106. Vict. Hist, of Bucks, vol. i. p. 130. Common winter visitor. Generally arriving about the middle of October and leaving towards end of March. Mr. Heneage Cocks formerly reported a specimen shot at Harleyford on July 28, 1871, and Mr. E. Burton Durham records one picked up in September 1913 at Chesham Bois (Field, September 27, 1913). On March 11, 1906, Mr. A. H. Cocks met with an enormous flock of this species resting in some meadows near Skirmett. The birds were thickly distri- buted over eight acres of grass land, so that allowing for one bird to each square yard, there must have been over 38,000 birds present ! In the cold winter of 1917 all or nearly all Redwings which were in the county at that time perished ; but in the following winter, though scarcer than usual, more Redwings were seen than Fieldfares. The cold winter of 1854, according to the Field, also destroyed Redwings and Fieldfares " by tens of thousands." In 1918 Redwings were generally very scarce. Hartert saw none until March, when he came to a place — a shrubbery of evergreens — where hundreds were roosting. In 1919 they were probably about as common as before the severe frost, and hundreds came to roost in the same place as the winter before, at least from January to March. 192 Novitates Zoolooicae XXVII. 1920. 72 (162). RING-OUZEL. Turdus torquatus torquatus L. B. of Berks, and Bucks, p. 136. Vict. Hist, of Bucks, p. 130. Passage migrant. Kennedy (I.e.) mentions a specimen shot at Risborough " in the spring " of 1840, and another observed by Burgess in his garden at Latimer, September 9, 1862. when specimens were also seen near Dundridge and Wendover. In Trans. Herts. Nat. Hist. Soc. vol. v. p. 82, specimens supposed to have been killed in July 1886, and in October of the same year, are mentioned. The former statement is probably incorrect, being from hearsay or recollection. In 1865 a male was killed near Burnham, and the Rev. H. H. Crewe observed specimens near Drayton Beauchamp, both in spring and autumn. Mr. A. H. Cocks informed Hartert, in lift., that one was shot near Chequers Court about 1878, and another at Stoke Mandeville " at least as long ago as 18S7." The Rev. Hubert Astley has several times observed Ring-Ouzels amongst the juniper bushes near Wendover and Chequers Court. In the Tring Museum is a (J shot at Wingrave 4 . xi . 1896, while others have been observed in autumn, and two shot near Tring, September 14, 1893. Mr. E. E. Pettitt saw one on the Middlesex border, near Stanwell Moor, on April 1, 1907 (in Hit.). 73 (164). BLACKBIRD. Turdus merula merula L. B. of Berks, and Bucks, p. 14. Vict. Hist, of Bucks, p. 130.

Mecocerus albiceps spec. nov. $. M. fasciculate Kolbe (1S95) subsimilis, rostro cum capite vitta alba signato, elytris area albo tessellata dorsali communi magna in medio valde constricta. Rostrum latum deplanatum, dorso bicarinatum, basi sulco brevi mediano instructum. Pronotum sparsim granulatum ; carina dorsali recta in medio levissime interrupts, versus latera angulata, carina laterali alta. Elytra pone basin gibbosa, seriatim punctata, striis 1* et 2" parum impressis. Long. 12 mm. ; lat. 5'5 mm. Hob. Nguelo, Usambara ; 1 $. In the style of colouring the species agrees with Physopterus melanoleucvs Jord. (1913). The rostrum is broad, and bears dorsally on each side of the flattened median area a rather broad carina which is slightly bent outward in the middle and is distant from eye. At the base there is a short median groove, and another shorter and more rounded groove is situated beyond the centre, where the carina* widen and disappear ; between the second groove and the apical margin a slight median carina ; between the dorsal carina and the raised edge of the antennal groove the rostrum is impressed, but there is no sulcus along the carina. Frons broad, being anteriorly at its narrowest point half as broad as the rostrum is long, measured in the middle. The occiput brown, the white stripe tripartite. Antenna pubescent white, club with the exception of the base of segment 9 rufous brown ; segment II much shorter than III (measurements 7 and 10), IX in length like III, VIII and X like II, and XI a little longer than X. Pronotum much rubbed, with indications of an ochraceous median vitta ; at the sides a large basal ochraceous spot ; laterally and along the carina dispersed granules, on the disc a shallow depression ; carina with a small forward angle nearer the sides than middle ; lateral carina very prominent in dorsal aspect. Elytra with the base very distinctly marginate ; a large patch of white spots extends from the subbasal humps to the beginning of the apical declivity, in middle confined to the sutural interspace, anteriorly reaching to the third row and posteriorly to the fifth ; a white spot above shoulder and a few dots here and there ; the rows of punctures not impressed, with the exception of the first and second ; base and sides spotted with ochraceous. Pubescence of underside greyish white, side of metasternite ochraceous. tip of metepimerum white ; mesosternal process broader than long. Tibiae rufous brown, grey near base and beyond middle ; first and last tarsal segments grey with rufous-brown tips, second segment with few grey hair-scales ; first foretarsal segment longer than fourth. '2. Mecocerus balteatus spec. nov. $. Niger, subtiliter brunneo pubescens ; elytris, metasterno abdomineque pube cinerea densissime tectis, balteo lato nigro cinctis. Hab. Benito, Spanish Guinea ; 1 ?. NOVITATES ZOOLOGICAE XXVII. 1920. 261 Near M. oculatus Jord. (1895). Head, rostrum, upper- and underside of prothorax, the extreme base of the elytra, mesosternum, apex of metasternum, and base of first abdominal sternite black clothed with a mummy-brown pubescence which does not conceal the dark colour of the derm ; rest of body covered with a dense ashy-grey pubescence which has a faint luteous tint ; on the elytra a transverse black band, 3'5 mm. wide near suture, narrowing at the sides, continuous with the transverse band of the underside, slightly brownish in sutural half ; the narrow basal band widened at the shoulders. Legs black, with thin grey pubescence, which is denser on the tarsi. 3. Mecocerus de missus spec. nov. ?. Niger, omnino schistaceo-griseo pubescens, elytris fascia transversa nigra notatis. Hab. Gaboon (A. Moequerys), 1 $, type ; Benito, Spanish Guinea, 1 $. Likewise a near ally of M. oculatus. Uniformly slate-grey, with the exception of the brown club of the antenna and a black median band on the elytra. This band is a little more than 1 mm. wide at the side ; it narrows slightly above and does not quite reach the suture. In the second specimen the band is broader and extends across the suture, but is much shaded with slate-grey and only its anterior boundary is well defined, while posteriorly the band fades away. Possibly both this form and the preceding one may ultimately prove to be colour varieties of M. oculatus. Several of the African Mecoceri closely resemble certain Longicorns (e.g. Acmocera), and among mimetic species one must always expect to meet with polymorphism. 4. Mecocerus modestus spec. nov. cJ$. Signatura elytrorum M. annulipedi Karsch (1882) simillimus, sed constructione M. clathrati Jord. (1903). Long. (cap. excl.) 8-10 mm. Hab. Johann-Albrechtshohe, C'ameroons (L. Conradt), 1 pair, type <$ ; Cameroons, 1 Warren's type). Forewing beneath in general less heavily suffused with red than in festiva. Dutch New Guinea : Upper Setekwa River, 2,000—3,000 ft., August 1910 (type and two other JcJ), September 1910 (1 ; SC!— R1 stalked for about half their length ; similar to forewing, the first line undeveloped, the median incurved proximally to the cell-dot. Underside with the cell-dots and the postmedian costal dot of forewing strong, otherwise more weakly marked, the median and postmedian lines fairly well developed, terminal dots nearly as above ; costal margin of forewing ochreous brownish. La Plata town. Type in coll. Tring Museum. A very ordinary-looking little species, yet not particularly reminiscent of any other. In some respects, though rather whiter, it somewhat recalls Scopula albidulata Warr. (Novitates Zoologicae, iv. 432). 24. Ptychopoda subfervens sp. nov. 5, pi. 52, fig. 1) described and figured 8. n.

INTRODUCTION. rpHE present treatise, though published under the auspices of Lord Rothschild -L and Dr. Jordan in the Novitates Zoologicae of Tring, must be regarded as a sequel and continuation of my Sphingidae of Peru, produced by the Zoological Society of London in their Transactions for 1912 (vol. xx part ii No. 1). It was due to the warm appreciation of the results of my self-imposed task on the part of certain entomological friends in Tring and London that this small work was privileged to see the light. My information at that time was accumulated during a three years' sojourn in Lima, from which I made occasional expeditions over the Andes into the hilly, well-watered, and thickly-forested region of the Interior as far as the river Perene. The volume comprises notes relating to 47 species, with many coloured figures of the early stages of some 22 which had come under my direct observation and been verified, together with a map of the limited district which I had the opportunity of exploring. The investigation of the early stages of Lepidoptera in general has for many years been to me the special charm of collecting, even in England, where, by comparison with distant Peru and other parts of the tropics, almost everything relating to larvae and food-plants is already known. An opposite state of things, however, prevails in S. America, where the large majority of its splendid butterflies and moths are known only as regards general locality in the winged condition. Little by little, at any rate, the different species of kindred or widely-separated groups have been falling into line ; and though in so vast a field of research the work of an individual for a lifetime can never be more than a measured contribution, I am now in possession of voluminous notes and figures relating to the larvae and pupae of Papilios, Morphos, Caligos, other butterfly genera such as Heliconius, Danais, Ithomia, Prepona, Calonephele, Ageronia, etc., the Notodonts with their wondrous diversity in larval form, the Bombyces, Saturniidae, and Limacodidae with their extraordinary spined and stinging caterpillars ; and last, but not least in interest, tfte elegant and highly-developed Sphingid family. 22 334 Novitates Zoolooicae XXVII. 1920. My hunting-ground, though remote from the former, and separated from it by some 3,000 miles, is nevertheless part of the same continent, and possesses a climate and a vegetation widely different from the Pacific Coast, but not altogether dissimilar from the Interior of Peru. The continuity, therefore, of my former investigations has been emphasized by the recurrence of species of wide distribution, and this to an even larger extent than I had anticipated. Common insects among the Hawk-moths, like Herse cingulata, Pseudosphinx teirio, Eriinnjis ello, etc., are known to have an enormously wide range in the American continent, reaching in some instances from Canada to Argentina, and from the Pacific Ocean to the Atlantic, inclusive of the West Indian Islands ; but I have been not a little surprised, when tabulating my Para species, to renew acquaintance with so many old friends. In Sphingidae alone I find that no fewer than 25 out of the 47 Peruvian species occur here in greater or less abund- ance. Now, after some eight years' residence in the immediate vicinity of the city of Belem (Para), my total list of Hawk-moths has just reached 90 distinct species — a remarkable number when contrasted with the mere 30 which the climate of Europe can support, or the 912 or so known to the entire world. In addition to the 22 species of which I have been fortunate enough to find the larvae, figure them, and more or less study their habits and food-plants according to the opportunity, 17 of this number being common to Para, I am now similarly informed in regard to at least 46 other species, not hitherto obtained or remaining unidentified. The larvae, generally at full growth, sometimes also in the earlier instars, together with a few characteristic pupae, have been figured life-size in water-colours, with all the patient care and faithfulness to detail which I could command in the matters of size, form, and colour. The pupae in many instances throughout an entire genus, such as Xylophanes, approximate to a certain standard or generic pattern, and the highly-important differentiating characters between allied species, such as those supplied by the form of the cremaster, are too minute to portray except by photography or by enlarged diagrams. For other reasons I have been obliged largely to eliminate the portrayal of the food-plants. Judging by numbers alone it would seem that Para is by far the richer field for Sphingidae, and this of course is true if balanced against Lima, which is merely an oasis of green on a desert coast. But when a comparison is made between the mouth of the Amazon and its head-waters in the region of Chanchamayo and Perene, it is by no means so easy to form a just relative estimate. Wallace and Bates discovered many butterflies in Para, but they never even saw many of the Hawk-moths which I find commonly here, and for the simple reason that in their day there were no electric arc lamps to attract them. There are none in the wild Interior of Peru to-day, and the wonder is, looking back at those hasty mule-back trips of ten days at a time, and not always at the best time, that one caught so much. Except for stray moths taken by day, or subsequently bred from larvae on those rare occasions when all con- ditions were favourable, the only attraction after dark in those parts was a solitary kerosene lamp. Here, in Belem, conditions are very different : we live in the midst of swamp and forest unending, 100 miles from the open sea, with the great muddy, tidal river in front of us, intersected by innumerable islands, and each one clothed to NoyiTATEg Zoologicae XXVII. 1920. 335 the water-line by an impenetrable tangle of trees and creepers. We live also in a blaze of electric light nowadays, and from far and near come the moths under the baneful influence of our nightly illuminations ; and this to such an extent that what was once superabundantly common when the electric plant was first installed about 1895, is now comparatively rare, through a process of decimation, as I suppose, within the area of light's attraction. Whether my explanation is adequate to account for the diminution I cannot say for certain, but many bear witness to the fact that there has been an obvious decrease in the number of corpses beneath every brilliant arc lamp since 1908, when the road- cleaners would sweep them up by the bin-full at a time. It is true that Erinnyis ello is still so common in the early months of some years, that on certain occasions it is no exaggeration when I say that I have counted over 200 at a single lamp. Thick, like a swarm of bees, they definitely obscure the light as they swirl around the globe or momentarily settle upon it. The insulated wires are practically invisible, so thickly are they coated with moths, giving them the appearance of being tattered to rags. On every adjacent object does ello settle, walls, palings, tree-trunks, foliage, and even human beings, while many lie squashed on the pavement beneath the feet of pedestrians or by vehicles in the road. Of no other species, however, in these parts can the same be said ; and having now lived in Para for considerable periods on and off since 1911, and having worked the lamps at all times of year and searched every available part of the matto surrounding the city for larvae and imagines, I have come to the fixed conclusion that we possess an immense and extensive ento- mological fauna, corresponding to the vegetation, but that hardly anything is really abundant. Species in plenty but paucity of individuals is a characteristic of Belem, as opposed to other parts of the States of Para and Amazonas up-river, where butterflies like the Pieridae, for example, may sometimes be caught, 40 or 50 at a single stroke of the net. These remarks apply with special force to such families as the Erycinidae among the butterflies, and to the Syntomidae, Limacodidae, and Notodontidae among the moths, and they are no less applicable to the Sphingidae. Statistics in the matter of relative abundance are apt to be erroneous and to defy conclusions, but my experience seems to suggest a fairly equal grouping of the Para Sphingidae under four heads, as follows : Single specimens or very rare ; rare or of spasmodic occurrence ; hidden but not rare ; common and occasionally abundant ; about 22 in each group. It is worth while to examine, and as far as possible to co-ordinate, the various causes which make for the abundance or scarcity of particular species ; for apart from the disturbance of nature's balance by the introduction of brilliant and attractive lights, for which man is responsible, there are many important factors over which he has little or no control, and which claim the attention of every observant person. Let us consider first the species which are abundant, and see why this is probably the case. Our conclusions "rank under three heads : ( 1 ) General hardiness and adaptability of larva to withstand various climates and thrive on various food-plants. (2) The abundance and wide distribution of suitable plants. (3) The comparative or total absence of parasitic attack. All these conditions appear to be fully satisfied in the case of ello, which is 336 Novitates Zoological XXVII. 1920. doubtless the commonest Sphinx hi the American continent, and so can still afford, better than any other, to lose a few millions periodically at electric lamps. Only once in numerous examples have I found it affected by dipterous parasites. The next point to notice is that Euphorbiaceae, with which the larva is chiefly associated, is an immense and widely-distributed Order of plant-life, and also that ello largely facilitates matters for itself by being able to feed freely on very many species belonging to different genera of that order. My idea, in short, then, is that the insect is hardier, and has a wider range of distribution, than any one species of those plants which sustains it as a larva ; and as one after another fails when the tropics are exchanged for the colder regions, its place is taken by some other plant which provides an equally nutritious pabulum. The chief means of sustenance in the Para region for ello are apparently two in number, the rubber tree (Hevea brasiliensis), for which Para is famous, and the mandioca [Manihot utilissima), for which it is hardly less so, providing, as it does, the native substitute for bread and starch from here to the coast of Peru. Even with this abundance others are occasionally preferred, and thrice, to my surprise, have I discovered ello associating itself with the entirely distinct Order Sapotaceae, and feeding on the leaves of " abiu " (Lucuma caimito). In two of these cases, being half-grown, the larvae stoutly refused to eat anything else. One died of starvation through my too-prolonged experiment with other leaves ; with the other I gave way, hoping that possibly I had discovered the larva of E. lassauxi, a totally distinct creature associated with Asclepiadaceae, but this I only learnt three years later. It was carefully figured to note subtle points of difference, but on emergence, to the banishment of my hopes, it produced but a perfect and typical ello. In Barbados ello feeds on the deadly " manchineel " (Evphorb.) ; and in the Lima district it was more often found feeding on Euphorbia pilvlifera and heterophylla, Cnidoscolus fragrans, Cvrcas piirqans, and Poinsettia pulcherrima. Continuing this line of research, we pass briefly to such common and widely- distributed species as Herse cingulata, the Convolvulus Hawk of America, the larvae of which thrive equally well on the cultivated sweet potato of these parts, with its abundant wild variety called " salsa," as they do on any species of true bind-weed from north to south and right across the continent. This species, again, seems to enjoy complete immunity from parasitic attack. A few other examples may be cited, e.g. Protoparce sexta, a Solanaceous feeder, which is very widespread, and is as .much at home on the potato and tomato of North America as it is on the tobacco, the capsicum peppers, or the " jurubebas " of hotter parts. Within the great Order of Solanaceae, though more especially in the genus Solanum, there is never the lack of appropriate fodder ; and once again I have only occasionally found this species troubled with dipterous and hymenopterous parasites. Pseudosphinx tetrio, an Apocynaceous feeder, though limited to Plumiera, is never at a loss in establishing a large gregarious brood of larvae, which will as readily defoliate the Frangipanni trees adorning the gardens of the West Indies and Brazil as the many still undescribed species of that genus, known here as " sucuuba," and ranging throughout all the more open parts of these tropical forests. Never have I discovered any parasite which attacks this most showy and abundant caterpillar. Pachylia ficus, another very common and widely-distributed species associated with Moraceae, I recall for the particular purpose of showing Novitates Zoolooicae XXVII. 1920. 337 that her adaptability to environment gives us at least one of the causes of her abundance, and affords a fine example of the working of an unerring instinct in regard to the distribution of her ova. I have learnt some botany from her at first-hand, and also a new riddle, which I may perhaps be pardoned for quoting as a good instance of appearance deceiving the eye, viz. — When is a willow tree not a willow tree ? — When it is a ficus ! Such a tree grows in our Botanic Garden in Para, and was at first quite erroneously recorded by me as a Salix. After repeatedly finding the caterpillar of this species on it and on many other trees of very distinct form and foliage, if I have not yet learnt how many different species of Ficus there are, I at least realize how deep and sound were the lines of our scientists, who, under the titles Moraceae and Urticaceae, were bold enough to group with Ficus such dissimilar trees as Artocarpus and Cecropia. On representatives of all three genera the larvae of Pachylia, especially P. syces, are often found feeding. My friend and botanical instructor of former days in Para, Dr. Huber of the Museu Goeldi, and a botanist of the very first rank, was greatly impressed with this interesting sidelight on our parallel studies. In their own limited degree, and in accordance with their particular needs, there are no finer botanists in the world than the moths, nor any such savants in the minute details of organic chemistry ; for, by methods beyond our com- prehension, they know exactly where to lay their eggs, and of what particular shade of composition those leaves must be to admit of nourishing their progeny, or of even providing them with their first green meal. P. ficus is sometimes, but rarely, stung by the same small hymenopterous fly which, in Para, too frequently brings about the destruction of its congener, P. syces. We have instanced enough by way of example, taking a few of the commonest species, to show, I hope correctly, why they are common. Everything is a matter of degree, and the conditions, favourable or un- favourable to the life of a species, would appear to differ in every case. In regard to the scarcity of many species, I have occasion throughout to point to causes which are traceable, and which, whether acting singly or in combination, are obviously enough to bring about the rarity of rare species, and reduce others to well-nigh the point of extinction. Before, however, considering these causes, there are other points in regard to abundance and wide distribution of which we must take account. The first is that such species as ello, cingulata, sexta and tetrio among those instanced, as well as many other moderately common forms like Pholus labruscae, are known to be long and strong fliers, as evidenced by their capture at sea and on the cold inhospitable heights of the Andes, far away from the localities and plants which gave them birth. This propensity of wandering, though it must result in the destruction of scores of individuals, betokens an extraordinary power of endurance, and exhibits an inborn tendency to spread and to establish when conditions are favourable. That this has been the case with many, one cannot doubt ; that it fails of its purpose in other instances, and more by faulty climatic conditions than by any shortage of food, is equally apparent. This is well illustrated in the case of P. tetrio, which was sometimes intercepted in its long flights over the Andes by the electric lights of Cerro de Pasco at an altitude of nearly 15,000 feet above sea-level, but which also frequently reached the coast from the Interior. There in the neighbourhood of Lima, the Frangipanni, its 338 NOVITATES ZOOLOGICAE XXVII. 1920. food-plant, was common in gardens, but the conditions were chill and gloomy, and never once could I discover its very obvious and easily-found larva, or induce a captured female to lay eggs. In England, to take a parallel case, we never tire of regretting that Euphorbia on the south coast and Galium on the sandhills of Lancashire are not enough in themselves to induce the lovely Celerio euphorbiae and C. gallii to take up their residence among us permanently. Returning to the question of abundance, an important feature to note is the greater hardiness sometimes observable in the larvae of many common species over rarer forms, the latter appearing to be more delicate and fastidious and susceptible of attack. Often have I noticed that a rare species, though provided with suitable food, will in many cases absolutely refuse to eat, if sealed up within the confines of a biscuit-tin ; whereas common things like sexta will finish off every scrap of leaf and stalk, and manage to pupate somehow, though deprived of nature's bounty. Fortunately, nature can provide no such harsh parallel, but even in the wild state caterpillars, like other creatures, have troubles many and various to meet ; and the extra degree of hardiness to withstand every wind that blows may quite conceivably spell the salvation of the individual and the increase of its kind. The percentage, too, in the death-rate of pupae, considered in relation to the brevity or longevity of the pupal period, is another factor of importance to note. Under artificial conditions this is certainly a very variable quantity with different species, but for that very reason it is difficult to generalize and to say exactly what happens in nature, for better or for worse. Undoubtedly here, as with larvae, some are more delicate, and are more readily influenced for weal or woe than others by conditions of humidity and temperature. The last point I wish to make in connection with the abundance of those species which we have been considering, and many others almost equally common, is that in proportion as they are common, due allowance being made for the limitations imposed by climate, range and extent of food-plant, general hardiness, etc., so are they comparatively free, not from outside foes, but from that still more serious and deadly complaint, parasitic attack in the early stages, which is generally irremediable. By this I do not, of course, mean that their abundance gives them any such immunity, but that the immunity which they enjoy in this respect is at least one of the prime causes of their abundance. This I take to be a most important consideration, and though even here there are exceptions, I am convinced that the converse is equally true, viz. that the rarity of many rare species, where the struggle for existence is obviously very severe, is primarily due to excess of parasitic attack in the early stages of those species. Doubtless all this is governed by the laws of nature, and summed up under the principle known as the " Survival of the Fittest," but I am bound to confess that I do not like the term, when thus applied. If, at any rate, my views are sufficient to explain why many species still remain common, we cannot deny that many others are rare ; and in facing the problem of rarity, which we must now do, and in searching for its causes, it is well perhaps to take the least important first and deal with the rest in an ascending scale. novitates zoologicae xxvii. 1920. 339 Climatic Conditions. The weather must, of course, come in for its fair share of blame, but Para would not be Para without it, and all things considered we enjoy a really wonderful climate, the advantageous conditions which it produces being far in excess of its drawbacks. (See General Conditions, p. 358.) My accusations, therefore, under this head shall be limited to the following : Torrential downpours of rain, preceded by sudden sharp gusts of wind of short duration, which undoubtedly dislodge various larvae, and bring to their certain doom many that have only just emerged from the egg ; floods, which must occasionally drown ill-located larvae and subterranean pupae, but to what extent it is impossible to estimate ; excessive humidity, which frequently, even in nature, produces fungoid growth to the destruction of pupae with or without cocoons ; excess of direct sunshine, which in certain localities burns pupae to death, or deprives larvae of pabulum by drying up the food-plant. Such troubles, however, in Para do not amount to more than, if as much as, they do in other parts of the world, nor do they apply in any special measure to the Sphingidae. In fact, my experience inclines me to the belief that even collectively they constitute the least of the destructive forces which act and react upon the forms of life under consideration. Predatory Foes. A far greater responsibility undoubtedly rests with certain predatory foes, which comprise a woefully long and varied list. To illustrate this, I can but catalogue a number of individual instances which have come under my direct observation, as follows : (1) The " bemtivi " or golden tyrant, which is frequently seen assisting the lamp-cleaner by consuming Hawk-moths as well as the smaller fry left from the previous night. Not content with mouthfuls in moderation to be found in genera like Epistor, Perigonia, and Sesia, he sometimes has the audacity to sample with his damaging beak the large and showy representatives of Protambulyx, Amplypterus, Oryba, and Pholus. (2) The " bacurao " or night-jar, which carries on the same murderous game at night, waiting silently on the ground just outside some illuminated area in an open place, and rising to snatch the moths as they are drawn to the light. (3) Other insectivorous birds, small and great, and too numerous to mention, of such families as Formicaridae and Dendrocolaptidae, whose life's occupation is to hunt insect-eggs and caterpillars on leaf, stem, and trunk, and peck open cocoons. Though I cannot here cite special instances, it can hardly be doubted that young Sphingidae, especially when green, perish thus in considerable numbers. (4) Coming to domestic regions, the barn-yard fowl, the cat, and that par- ticular type of pedestrian whose mind is as heavy as his boot, I rank in one class, though they are not all birds. To their united and vandalistic efforts in the immediate vicinity of dwellings must be ascribed a very considerable shortage in those forms of living creatures which were surely meant to adorn the earth, and which are just as harmless as they are beautiful. Ignoring the obvious ravages of the hen and her brood, the chief victims are large Sphingid moths, 340 Novitates Zoolooicae XXVII. 1920. " played " to death beneath every other street-lamp at night by cats, whose more normal avocations in life are temporarily suspended. Then come the great larvae of such genera as Cocytius, Protoparce, and Pachylia, which from their size, movement, and vivid coloration on the dead earth or pavement are very conspicuous objects, as they wander in search of suitable places to pupate. The destructive instinct at once comes uppermost, and is unfortunately not limited to children and school-boys. Though in many cases not in the least like snakes, they are, of course, always taken for them, and must be squashed or cut in half. (5) Of insect-eating animals I cannot speak from personal knowledge, but from the way in which small monkeys greedily devour cicadas, it is not un- reasonable to assume that Sphingidae have foes even from this quarter. (6) Then come the bats, whose ravages are but too well known. Though Vampirus is mainly a fruit-eating genus, and others have a decided taste for human and animal blood, the nightly destruction which prevails among the winged creation in general, Sphingidae included, must be enormous beyond computation. On favourable evenings in the main public square of Para, the central pavement of which is adorned with a monument and four brilliant arc lamps, I have seen as many as twenty very large bats at the same time, sweeping in and out of the illuminated area, twittering vociferously in chorus and devouring everything wholesale. I have many times seen one actually cling for a brief moment to the wire hanging in proximity to the globe, gobble an cllo or two, disturb half a dozen others with its wings, and decamp. (7) Under the general head of reptiles, but especially lizards, the destruction of Sphingidae, as of other families, is again enormous. The electric lamp is once more the rendezvous for toads and frogs. There are huge olive-brown, fat-bellied toads sitting beneath and ready to swallow up anything that is unwary enough to alight on the ground, or being dizzy, and perhaps singed, falls within the range of their leap. There are small frogs of several tree-climbing varieties, which I have frequently seen not only clinging to the smooth iron of the post, but on occasion quietly enjoying their suppers in line with forty or fifty Hawk-moths upon the insulated wire leading to the globe. Never, surely, was there such a place as Para for lizards in the matters of size, abundance, and variety. They are to be found in every part of the matto, wet or dry, in every garden, on every wall, and even in every house ; for a small sand-coloured and semi-domesticated cousin, named " osga " (Hemi- dactylus), is suffered to abide with us, because he is fond of mosquitos. " Osga " also sits upside-down on enamelled lamp-reflectors at night and waits for moths. I counted five the other day in passing a dozen street-lamps. But the point to remember above all is that all lizards and snakes, so far as I am aware, eat caterpillars and chrysalides, morning, noon, and night, and have apparently solved the knotty problem most satisfactorily to themselves, that they of all creation are the fittest to survive. The " acapu " palings which line the roads and gardens of Para are largely tressed with creepers like Cissus, Echites, Davilla, etc., and they are also thronged with lizards, untiring in their quest for food. It is here that many heedless Hawk-moths of such genera as Pholus, Epistor, Aleuron, and Leucorhampha deposit the greater portion of their ova ; for it is here that I have periodically been successful in securing a first innings at the egg-laying season. Novitates Zoolooicae XXVII. 1920. 341 Assiduous and prolonged searching results in the discovery of many ova and young larvae of these species on the out-branching tendrils and freshly- expanding leaves, but not for long will you find them there. A number of empty egg-shells and recently nibbled leaves too often betoken only that the devourer has been devoured. A fortnight later you will be fortunate if you discover a single caterpillar that had somehow escaped detection, and become too tough and fat or too snake-like to be eaten ; for in such positions the waste must be enormous, and it is clear that only the merest fraction of this potential life can ever reach maturity. Considering the perpetual depredations of lizards alone or in conjunction with other foes, the marvel is not that the majority of butterflies and moths are scarce hereabouts, but that many species which are rare survive at all. Possibly some have disappeared by this agency, and I presume that we shall none of us ever be any the wiser. Possibly they represent some of the missing links in that great chain of life of which to-day we behold but remnants in certain isolated units which seem to hinge-on to nothing and to defy classification. (8) Next come predatory insects. I use the term freely for convenience, to include all sorts of creeping, crawling, and flying creatures, which in turn bite, sting, and devour lepidoptera in all stages of life. Prominent among these are Arthropods such as centipedes and spiders, small and great, as well as lice, beetles and cockroaches, locusts and Mantidae, wasps and other flies, and last, but by no means least in effect, hordes of ants, whose ravages, whether conducted singly or by universal onslaught according to the habit of the species, certainly represent wholesale destruction on the grandest and most distressing scale. For the scavengers of refuse we have nothing but approval, but Para is so richly furnished that it has ants to eat everything, alive or dead, and half one's time is wasted in the futile attempts at warding off their insistent attacks. Besides the ants which fill your sugar-basin, eat your fruit, drown themselves in your drinks, and invade your entire food-supply, there are ants to consume not only your dried insects but living larvae and the young brood just out of the egg, which have been carefully sleeved-out on some growing plant. The sleeve-net is at once appropriated as the suitable locality for a new nest, with the larder already stocked at close quarters. On other occasions you import choice plants into your garden to serve in larvae-rearing, and during the night they are denuded of every leaf by a train of big red " saiiba " ants, whose earthworks may be in some one else's garden a hundred yards or more away. A very large solitary black ant known as " formiggo " (Ewponera) is often met with on the matto paths with a moribund caterpillar between his jaws. In short, there is not a place, not a tree-trunk nor a leafy bough, that is not the resort of one species or another of the ant world. They literally swarm everywhere, and are responsible for immense destruction. The attack of a common black predatory wasp has recently been very clearly demonstrated to me, still further explaining why the healthy young caterpillar of yesterday is no longer to be found on his perch to-day. In an attempt, which should otherwise have succeeded, to introduce a hardy species of Citheronia, found commonly at Pernambuco but unknown here, I reared some 300 young larvae from the egg. These were kept in the protection of my bathroom until they had reached the second or third instar, and were an inch 342 Novitates Zoolooicae XXVII. 1920. or more in length. Then, considering them tough enough to withstand the elements, and sufficiently heavily spined to ward off predatory foes, I placed them out in a large net open at one end upon a guava tree with profuse leaves in my churchyard. Three days later my 300 were reduced to 3 by this miserable black thief, several specimens of which were seen still exploring the boughs, while one was actually inside the net munching at mangled remains. As no further trace of the rest could be found, I presume that the majority had been carried off to the nest. Thus does the struggle for life continue, and I know of no place which offers greater facilities than Para for the observation of its diverse phases and features. Parasitic Foes. We come now in order to the last but most insidious branch of foes to which lepidoptera in their early stages are exposed — viz. Hymenopterous and Dipterous parasites. Once again Para is full of them, and doubtless in many instances they are in themselves undescribed species, or if they occur in collections, they at any rate lack any demonstration of that intimate relationship with the various species of lepidoptera on whose life's blood they were nourished in their own larval stages. I have got nothing new in principle to narrate over and above what is known to exist in Europe and other parts of the world, but only to record the very widespread and pronounced character of this unlovely association in Para, as evidenced by the large proportion of one's caterpillars, which to one's disgust only produce flies and wasps. These may be very interesting in them- selves, and I kill and label them off under the name of the host for future identification ; but as it is impossible to specialize in all branches of entomology at the same time, I will at once confess to being the victim of a relentless prejudice. Among the Sphingidae, as illustrations of what I have too often experienced, I may cite the following instances : The eggs, generally laid on the under-surface of the tenderest leaves of the food-plant, are frequently " stung " by some almost microscopic hymenopterous fly. After the lapse of but a few days there emerge from one or several holes ten or a dozen of its progeny, which, marvellous to relate, have completed their entire metamorphic cycle within the confines of the egg-shell of the moth. This I observed in Cambridge and Windermere years ago in the case of the common Emperor-moth's eggs, and I have very frequently noted it not only in connection with the large ova of Cocytius, Protoparce, Protambulyx, Pachylia, Leucorhampha, and Pholus, but even with the smaller eggs of Xylophones, and no species seems to be immune. In P. syces, L. ornatus, and X. chiron, guianensis, anubus, and especially mossi, the larvae are too frequently stung by dipt era, producing from 10 to 30 maggots with imagines resembling blue-bottles or the common house-fly. Many are subjected to attack by both diptera and hymenoptera ; the larva of X. anubus, for example, once producing a single and very large wasp grub which spun a tough black silk cocoon. The genus Protoparce is similarly troubled, not only by Diptera (the eggs of the parasite in this case being generally introduced in the region of the spiracles), but also, though more rarely, by a small wasp. In this latter case the full-grown grubs of the parasite emerge through the back and sides of the still-living but NOVITATES ZOOLOQICAB XXVII. 1920. 343 sadly attenuated host, and spin little yellow or white silken cocoons in situ, standing up on end and reminding one of the almonds which sometimes adorn a plum-pudding. The larvae of a small Hawk-moth in Pernambuco, Neogene dynaeus, is thus literally decimated. On corresponding lines the genus Pachylia, especially syces, which is so much rarer in Para than ficus, is stung by a very small hymenopterous parasite, resulting in the production of some hundreds of tiny flies from the body of a single caterpillar. In this instance, the larva, while still clinging to a leaf, becomes completely encircled by a mass of tiny white cocoons closely woven together. The writhing larva then falls out or is devoured by ants, and what is left appears to be a thick lump of cotton-wool sticking to the leaf, of tubular formation and open at each end. In the case of dipterous parasites which affect species belonging to Acherontiinae, Sesiinae, and Choerocampinae, and possibly the two other sub- families, the exodus of the maggots from the body of the caterpillar invariably takes place in the puparium, and even after the spinning of a slight but deficient amount of silk. These Diptera, though bearing a striking resemblance to ordinary flies, of course represent many distinct species. It is more than possible, however, that some of the common parasitic species are by no means restricted to any one kind of caterpillar, but thrive at the expense of the lives of a number of larvae belonging to different species and genera or even to different groups. In other families of Lepidoptera, such as the Saturn iidae, the larvae manage to pupate in stout, well-woven cocoons with all the appearance of health, and only later do the dipterous maggots break through the walls of the chrysalis within, and form their own glossy brown oval cocoons alongside the corpse of their victim. This sometimes takes place here with a few Sphingidae which spin a covering web interwoven with fragments in the crevice of a tree-trunk, such as Isognathus scyron. In other cases the metamorphosis of a species of Diptera, sometimes that of one large hymenopterous fly, sometimes that of a number of small ones, is completed within the confines of the pupa-case itself, from which the flies emerge by separate holes. This is frequently observed here, as elsewhere, as a pronounced feature with many species of lepidoptera, the first prevailing with the Saturniid genus Rothschildia. The last-named variety is especially marked in such species as Papilio thoas and androgens, Aganisthos odius, Brassolis sophorae, Opsiphanes, etc., among the butterflies ; and I have only recently discovered that Isognathus allamandae Clark in Pernambuco is similarly attacked, though up to the present I do not remember to have bred any Sphingid parasite of this particular kind in Para. For the sake of completeness, as being a prevalent form, one other type of dipterous parasite deserves special mention. How far it attacks Sphingid larvae I cannot say, but the large Nymphalids of such genera as Caligo, Catoplebia, Opsiphanes, Dynastor, and Prepona are very extensively troubled by it. The method of egg-laying on the part of the female parasite, which I have caught in the act of ovipositing, is different, and for a brief period one degree less damaging, in that it gives the caterpillar, or rather its captor, a fighting chance. This I have repeatedly proved after a painstaking operation with the forceps, in which the temper of the " stung " caterpillar is sorely tried. The eggs, which are ochreous and tough, are gummed on. externally with diabolical accuracy of instinct, sticking like ticks at one end immediately behind the horned head of 344 NOVTTATES ZOOLOOICAE XXVII. 1920. the larva and in the interstices of the segments, so that the poor victim cannot bite them off. If found before the young maggots have hatched and eaten their way into the host's body, they may with great patience and care be removed, one at a time, 10 to 50 of them, and the larva will pupate and emerge as perfectly as if it had never been scented-out by so unwelcome a visitor. This method of procedure is adopted by certain species of Diptera in England, and I have more than once found the noble1 larva of Oryba kadeni thus molested. Such, then, are the forces of decimation among the butterflies and moths of Para, and with parasitism in insect life I close my mournful list. The word, from being originally applied to the drone in human society, has come now to be used somewhat loosely, thereby losing some of its original force. In a true sense the cuckoo, which has ceased to build a nest and rear its own progeny, is a parasite. My use of the term here, however, is strictly limited to what I consider to be degenerate forms of life, whose evolution has had a downward tendency, and has involved the loss of an erstwhile independence by an unorthodox dependence for nutriment upon the living and prepared juices of another species in the same general order of creation. Such is our mistletoe, which no longer needs roots, but sucks the prepared sap of the apple-tree and the oak, and survives at their expense. Such is the Brazilian mistletoe, clustering as a thick yellowish mass among the upper branches of Genipa americana ; such also is the " herva de passarinho," which diminishes the health and fecundity, if it does not curtail the growth, of the orange and mango, and others like the " abacate," among the more indigenous trees of Brazil. Such, however, is not the orchid, which, like many another plant (ferns, Bromeliaceae, etc.), only finds a lodgment and support upon the trunk or branches of a tree, does not derive nourishment from its sap, and is quite erroneously termed " parasita " in the Portuguese tongue. Of parasitism among the insects I have already said enough to make my meaning clear. That it has its uses in preserving the balance of nature by limiting the over-rapid increase of those species attacked cannot be doubted. It is a selfish and harassed world in which we live, and just as parasitism looms large as a universal feature, so are we bound to acknowledge that this trouble in the insect world is quite in order. My contention therefore is, not that it is right, but that, so far as the present age is concerned, it is in full accord and harmony with those laws which we find actively at work in every other department of life. I contend, on the other hand, that it is very far from ideal, and that by no stretch of casuistry can it be reconciled with the assertion made in Genesis (chap. i. ver. 31), that " God looked upon everything that He had made, and behold it was very good." No matter how allegorical such passages as these may be, no matter how deficient as scientific statements, they stand, in my humble estimation, in their broad general outlines for essential truth. And, though it may be thought fanciful, I fail to understand how persons who refuse credence to the second great dogma, known as " the Fall," can effect any sort of recon- ciliation between nature and revelation. Accept " the Fall," and parasitism at once becomes at least intelligible as a part, not of a fair creation, but of a disorganized and perverted system ; and at the same moment, in the marvels of the Divine economy, one of the means necessarily resorted to to prevent matters from becoming worse. Not therefore by adopting the so-called " scientific " view of former days, Novitates Zoologicae XXVII. 1920. 345 not by ignoring the theological tenet regarding a fallen state, which for too long has been deemed at variance with the theory of evolution, but by accepting both the statements of the Bible and the plain truths of nature can one read Darwin and Wallace, and may I add Huxley, with the immense pleasure and profit to be derived from almost every page of their writings. And, further, I claim that one can emerge from this fiery ordeal not a rationalist, still less an atheist, but a believer still and a fuller believer, whose creed, if it has been subjected to the rationalizing process, has only been shorn of immaturity and excess, and readjusted to an altered perspective. By way of forestalling a possible criticism, it is obvious, from the previous verse to that referred to in the first chapter of Genesis, that vegetation was meant to serve as food for animal life and creeping things, and it is equally obvious that man was meant to eat animals ; but all this is the direct opposite" of parasitism, taken as I understand the word. To summarize, then, I cannot conceive it as any part of a very good creation, though evolutionary changes subsequent to " the Fall " may have necessitated it, that, for example, a healthily-nourished caterpillar, which has in itself all the potentialities of becoming that for which it was intended, viz. a perfect butterfly or moth, should have its vitals consumed by another creeping thing, the larva of another insect, in fact, simply to complete its own metamorphosis, no matter how equally perfect that other insect may be in the marvels of its own construction. Is not the world large enough for all ? Its near relatives still live on fruit or decaying wood or excrement, and at the least hasten on the purifying process whereby these substances are returned to their primal and scentless elements. The degenerate parasite, on the other hand, slowly tortures another living creature to death, and, having deprived the earth of an item of beauty so far in excess of its, own achievements, leaves behind a putrid and stinking mass for others to clear away. However much truth the term " Survival of the Fittest " may cover, it does so effectually cover up everything under that vaguely comprehensive and indefinable word " fittest," that it seems but to shelve difficulties. What is the fittest to survive, and why ? From what initial standpoint of enlightenment and authority do we argue that any one living organism is more fit to survive than another ? Is it not from all the evidence before our eyes, those plain broad facts which none can dispute or deny, that feeling bound to acquiesce in the inevitable we give it a name ? My objection is solely ranged against the word " fittest," for it seems to beg the question and to land us into an awkward dilemma. We all, for example, have our sense of beauty as opposed to ugliness, and there is even a general consensus of agreement upon the point. We all form relative estimates upon the practical utility and worth of things throughout the entire creation, animate and inanimate, and again there is a large general consensus of opinion. But how does nature deal with beauty and utility ? She is stern, relentless, and without discrimination, making no account whatever of our conventional standards and values. As often, in obedience to those elementary laws which enjoy universal sway, do her blind forces of destruction demolish the beautiful and useful as they burn rubbish. As often, in her milder moods, does she tenderly nurture the worthless weed by those same benign influences 346 NOVITATES ZOOLOGICAE XXVII. 1920. with which she fosters some type of growth that we account precious. We are left, then, to face two alternatives : ( 1 ) that our standards of appreciation and valuation, no matter how world-wide their support, are all wrong, which I do not believe ; for though confessedly conventional, they must bear some, relation to the absolute ; or (2) that, in the face of our ideas upon beauty and utility, those which actually do survive in the struggle for existence are thereby proved, ipso facto, to be the fittest to survive, which I no more believe. I am aware that I am employing the term in a somewhat unusual and restricted way, and it is in this sense only that I contend that the word " fittest " is made to do too much duty. At one time it stands as the equivalent of " strongest " or " cleverest," at another it simply represents superior brute force or the greatest cunning, or at best the most prepared. But it is when we come to a consideration of those disintegrating forces like parasitism among insects and plants that our rebellion against the use of the term " Survival of the Fittest " reaches high-water mark : for the successful parasite, though transcending the wisdom of a Solomon in the accuracy of its aim and in the attainment of its object — namely, supremacy in the struggle for life — does so by methods which are discredited and are altogether out of harmony with what we understand as the principles of justice and morality. Though it may serve a useful purpose in the general economy, judging by human standards, we are bound to acknowledge that on such occasions it is the fit which disappears and something worse, less valuable or less beautiful, which survives. Right or wrong, fit or unfit, parasitism is assuredly and immensely responsible for the reduced number of many representatives of practically all the lepidopterous families, and consequently for the reduction, almost to vanishing point, of one of nature's loveliest ornaments. Each of the five subfamilies into which the Sphingidae are now classified is represented in Para and in the following proportion : Acherontiinae 16, Ambulicinae 6, Sesiinae 47, Philampelinae 9, and Choerocampiriae 12; and just as there are many other species of a more or less restricted range of distribution in different parts of the immense region drained by the Amazon and its tributaries, so possibly are there even more species near the southern side of its mouth than the 90 or so which I have had the good fortune to come across. Due allowance must of course be made for this in any subsequent remarks dealing with the parallelism or difference which obtains between the species considered. I now have some observations to make in regard to the features, habits, and peculiarities of the Para Sphingidae, which, when correlated, apart from any intricate or anatomical questions, constitute a striking array of facts, and go far in suggesting a true system of classification. Those with which I wish to deal are five in number : (1) Form, design, and colour of larvae ; (2) Pecu- liarities of their excrement ; (3) Method of pupation ; (4) Form, design, and colour of pupae ; and (5) The association of species or even whole genera with some particular Order of food-plant. (1) Form, Design, and Colour of Larvae. Here I would notice at the outset the general similarity of young Sphingid larvae on emergence from the egg, suggesting the close alliance of each species, NOVITATES ZOOLOGICAE XXVII. 1920. 347 be it small or great, and forming the whole into one compact and well-defined family, irrespective of subfamily distinctions. The character to which I refer more particularly is the uniformity of the tail on segment 12, which at that stage is always a noticeable feature, of remarkable length, speedily changing from light to dark in colour, and when examined under the lens found to be rough in surface, frequently bi-lobed at the extremity, and surmounted by a single bristle on each fork. It is in this particular, or rather in the extraordinary variety of tail-formation, the partial or complete loss of this appendage in the succeeding stages, that we behold such striking specific differences. Stage after stage, as the skin is moulted and successive instars reached, does each species, ever true to its kind, exhibit a new form of tail or horn or hump, different from that which preceded it, different from that which is to follow, and in many instances, especially in the fifth and final instar, essentially different in length, thickness, quality, curve, and colour from even its next-of-kin in the same genus. This is most noticeably the case in the genus Xylophones, and perhaps least pronounced in Isognathus, where an exceptionally long whip-like black tail is retained up to the period of pupation, and where the difference between the various species in this one respect becomes more one of degree in length, roughness, and the presence or absence of a white ring or two. It is surely worthy of note, though I will leave it with those better versed in the laws of evolution to draw conclusions, that Isognathus is practically the only genus in Sphingidae, so far as I am aware, that retains the long, rough, flexible tail of the baby caterpillar to the full end of the larval period. Curiously a few deceptive Notodonts possess a very similar appendage. The kindred genera in this same subfamily Sesiinae exhibit very strange diversity of form in the tail, Erinnyis, the next-of-kin with almost identical pupa-form, being characterized by an appurtenance which in alope is like a rounded tusk, in ello and oenotrus like a swollen knob, and then a mere nipple-like point in the last stage. In Oryba achemenides, but not kadeni, it is like a sickle in the fourth instar and only a button or nipple in the final. In Enyo, Aleuron, Madoryx, and Leuco- rhampha, on parallel lines, the tail resembles a curved knife-blade, followed as before by the mere button. Hemeroplanes bears a rather stout grey and curved horn, while Pachylia has a small sharp spike in syces and a thick, blunt, but very diminutive hook in ficus. In Philampelinae the tail of Pholus anchemolus, after being reduced to a fine and absurdly disproportionate black hair in the foregoing instar, disappears altogether in the last. Its relatives Peacus fasciatus and vitis evolve on the same lines, but P. labruscae shows a new development, exchanging the flexible and curled pink filament of the fourth instar for a hard glossy disk, capable of a rapid undulatory movement. The Ambv.licinae, from my restricted acquaintance with their larvae, and the Acherontiinae, where I am more at home, seem in the main to possess what we are accustomed to regard as the normal horn, partaking more or less of the dorsal coloration of the larva or inclining to black, blue, or pink, stiff and stout in construction, though more slender in Ambulicinae, rather erect in posture, incapable of free movement, straight or finely curved, and generally bristling with small setiferous tubercles. Herse cingulata, Protoparce sexta and albiplaga are, however, exceptions to the rule, and, though it be only a matter of degree, exhibit strongly curved and rather smooth horns. In Choerocampinae the variety is so great that I fail in any attempt at description. Suffice it then 34S Novitates Zoologicae XXVII. 1920. to say by way of contrast, that Xylophones gnianensis possesses a broad, thick, and perfectly straight blade-like horn, rough like a file on both upper and lower edges, but smooth on the sides ; while X. mossi in its last instar retains but the merest vestige of a down-turned tail upon the anal flap. True to the principles enunciated by Darwin in The Origin of Species, it is this strongly pronounced but variable feature, representing, as I suppose, the tail or horn possessed by the ancestral Sphinx, and ante-dating the various later evolutionary changes, such as have necessitated subfamily divisions, which has shown the greatest amount of variability in structure throughout the entire family. Nothing short of enlarged photographic diagrams, showing the evolution of the tail of each species during its five successive instars, species after species 6et side by side for comparison, could serve adequately to portray the extra- ordinary degree to which this caudal appendage of the Sphingidae has varied. Coming to the later stages of larval development, colour and design, apart from their adoption as protective measures by resemblance to surrounding objects, seem also frequently, though with a few strange exceptions, to suggest a sequential progression, or at least a circular grouping of species. I refer in the first place to the seven lateral oblique stripes, so characteristic of Sphingidae throughout the world ; to their irregularity in Cocytius ; to the greater regularity of the same in Protoparce, P. albiplaga forming an exception ; to the fixed and constant deviation from the normal type, depending wholly upon the difference of food-plant in Protambidyx strigilis and Sesia ceculus ; to the extension of the seven to an eighth or even ninth stripe in species of Epistor, Sesia, etc. ; to an entirely distinct design in Isognathus, Pseudosphinx, Leucorhampha, and the later stages of Erinnyis ; to their transposition, pointing up towards the head instead of the tail in Pholus and Pachylia, P. resumens forming a most remarkable exception to this ; to their reduction to five in diminishing ratio in Pholus anchemolus and vitis, to six in eacus and their increase to eight in fascialus ; and, finally, to the partial reappearance of the customary seven stripes directed tailwards, when visible at all, in Xylophanes. The presence of a medio-dorsal stripe is again a characteristic attribute, appearing strongly in Cocytius, in many of the genera of Sesiinae, in Philampclinae, and to a partial extent in Choerocampinae, but seldom strongly marked in Protoparce and usually absent. Possibly a still more important and significant feature, specially characterizing the entire subfamily Sesiinae, with or without the addition of the oblique side- stripes, is to be found in the enclosure of the dorsal area by two lines adorning the face and continued at a slightly divergent angle, which then run parallel and unite somewhat more abruptly at the tail. This pattern is totally absent, so far as I know, in Acherontiinae, Ambulicinae, and Philampelinae, but reappears strongly in some species of Choerocampinae. Mere colour counts for but little, I presume, in the matter of classification, being so largely a question of adaptation, but even here there are features worthy of note. Though one occasionally meets with exceptions where the adaptation to surroundings is less perfect than in others, the rule of course holds good that green caterpillars with light stripes are to be found by day among the leaves which they so closely resemble in colour and design, and on which they feed, chiefly at night. Various devices are resorted to for protection during the day Novitates Zooloqicae XXVII. 1920. 349 by caterpillars which are not green, or better, when they cease to be green after any particular moult. It is thus with the later stages of Erinnyis, and more especially with Madoryx and Leucorhampha, the larvae reposing with two or three pairs of claspers tucked up and unused, geometer-fashion, on branch or trunk, where they are by no means easy to detect. It is thus particularly with those species of Xylophones which, while young and green or coloured like the stalk, are well adapted to stay in the neighbourhood of the fresh shoots on which they are feeding. Indeed, a long journey at this stage woidd be not only uncalled- for, but would entail fatigue and danger. Quite the reverse, however, is the case when, by successive moultings, the caterpillar has grown larger and stronger and become brown, maroon, or peat-coloured. Then almost invariably is it only to be found, if searched for by day, on the darkest and shadiest part of the trunk near the ground, or quite frequently, as in the case of X. guianensis, at some distance from the tree, lying on the earth among dead leaves and sticks, an extremely inconspicuous object. The habits of X. anubus, loelia, and tersa, in association with their particular plants, are identical ; but X. porcus and chiron, which remain green to the last, have no need to move and seem to be aware of the fact, finding an umbrella of leaves sufficient protection from rain and sun and from prying eyes. On several occasions I have found X. tersa by way of variety retaining a green coat to the end of its larval period, and then, as though it knew all about the matter, it was perched-up on the top of a spray of Spermacoce in broad daylight, apparently justified for once in ignoring the secretive habits of its kind. Poor X. mossi, which is nearly always " stung," is exceptional in its habits, and would appear to be in a dilemma on account of its bright colour. When young it is reddish-maroon, and there is no doubt that it wonderfully simulates the little tailed red sheaths of the newly-expanding leaves of Pagamea, where it rests and feeds. Sometimes it develops into a grey-green with growth, and it is then equally well situated by remaining among the leaves. Usually, however, the colour turns to a brilliant burnt sienna on the sides with a pink back, lemon-yellow bands on segments 11 and 12, and five (sometimes six) patches of viridian green marking the side-stripes. In this predicament, allowing for the fact that the stems and branches of Pagamea guianensis are of a bright sienna colour also, instead of seeking the shade it elects to stay, but is thus too easily detected if at all exposed to view. In the case of the highly ornate larvae of Pseudosphinx and Isognathus, there is generally no attempt at concealment beyond selecting the under-surface of a Plumiera leaf for shade, and sometimes frequenting the trunk or branches in the blazing sun. As the well-known arrangement of warning colours largely enters into their composition, alternating belts of black and white, or black with yellow stripes and red heads, touches of blue or mauve, etc., I presume that they are not wanted, and they certainly behave as though they were aware of the fact. In this immediate connection it is interesting to note, the exception incidentally proving the rule, that there are at least two members of the group which act differently in this respect, Isognathus scyron and allamandae. These larvae are of a grey-brown colour and distinctly dowdy by comparison with their more gaily- attired congeners, invariably hiding away in perfect concealment during the day on the dull branches or among the roots of Allamanda cathartica. They are not Plumiera feeders like the rest, and it is significant that they should be almost 23 350 Novitates Zoologicae XXVII. 1920. the only species of the group which I have noted as being occasionally stung by both dipterous and hymenopterous parasites. The mimicry of small snakes, if one is right in using the term, is a marvel- lously pronounced feature in some species, and is to be had to perfection in certain members of the Sesiinae subfamily, such as Madoryx and Leucorhampha, in Pholus labruscae as an exceptional development in Philampelinae, and again very specially in many species of Choerocampinae. As, however, this resem- blance is effected by slightly, or extremely, different methods in almost every case, I prefer to reserve the subject to individual treatment in connection with the species thus enhanced. (2) Peculiarities of their Excrement. The next point upon which I wish to touch is the peculiarity of the excrement or frass of Sphingid larvae, which though constructed, as I suppose, upon a fundamentally uniform plan, and very similar to that produced by Notodonts, Saturniids, etc., is strikingly different in distinct species, and very often acts not only as a guide to the whereabouts of a larva, but informs the practised collector in advance of its precise identity as a species. By this I do not mean to infer that every single species can thus be discriminated in advance, but that by previous acquaintance with the larva, its habits and its association with some particular form of plant-life, the colour, size, shape, and general character of the excrement will, in the majority of instances, if carefully observed, betray the genus and very likely the exact species. I know too little of the digestive organs of larvae to say exactly what takes place, but the model upon which the excrement is constructed, a pellet of hexagonal and tripartite form with a central core, is well illustrated by that which is produced by Cocytius in the final instar. At this stage, in antaeus and cluentius at least, it invariably breaks up at the moment of extrusion into 21 small brown fragments. In duponchel the pellet more often falls to the ground whole, but being of a dry character, and the divisions being well marked, it very readily breaks up as before into 21 pieces. For brevity I must confine my remarks to the last larval instar. In Herse the excrement is of an opposite character, being blue-black in colour, soft and wet, and consequently so far welded into one piece as largely to obscure the hexagonal design. This is even more the case in the genus Xylophanes, where many species deposit stiff black or dark brown pellets of enormous and seemingly impossible dimensions, and where the minute leaf-fragments are welded most compactly, layer upon layer in rough oval formation, showing but a trace, if anything, of the hexagonal design and nothing at all of the tripartite divisions or the core. It is no exaggeration to say that in the cases of X. guianensis, anubus, and mossi, for example, these pellets frequently approach an inch in length, and are proportionately thick. In these instances, though the larvae grow with exceptional rapidity, mossi never exceeding five days in its final instar and still fewer in each of the four previous stages, the number of pellets rarely exceeds 6 or 8 in the 24 hours. Conversely with other species where the excrement is small and neatly hexagonal, Sesia titan and fatbits, for example, will drop 50 or 60 pellets in the same time. P. sexta is a good illustration of this, being a hardy, voracious, and almost continuous feeder ; but of the Novitates Zoolooicae XXVII. 1920. 351 excrement of Protoparce in general it may be said that it is moderate in amount, well-proportioned to the size of the larva, fairly regular in form, and in colour dark brown, yellow, or green, largely in accordance with the nature of the particular plant upon which the caterpillar has been feeding. In Protambidyx the excrement of strigilis and eurycles is small and light green, the hexagonal form being subdivided and giving it an exceedingly regular appearance. This character is shared by Oryba and to a limited extent by Pachylia, in both of which cases the frass, though large, is not excessive for such big larvae. In Oryba kadeni and achemenides the colour is light brown, and as it does not readily grow mouldy it is wont to retain its form for months after the larvae have pupated. Its position beneath bushes of Palicourea or Ourouparia, as the case may be, coupled with its size and general formation, leaves one in no doubt as to the identity of the species, even if, as too often happens, one is too late to discover the whereabouts of the particular caterpillar. The excrement of Erinnyis and Isognathus is rather small, that of Pseudo- sphinx somewhat elongate, hard and black, with sharp angular projections and frequently bent. Pholus produces very large soft pellets of a light or dark green coloration with the hexagonal form obscured but not obliterated. So much at any rate for a subordinate branch of the subject, which, if not the most savoury, is by no means devoid of scientific interest and is well worth the attention of the student of larval habits and early stages, as it so often leads to new discoveries. (3) Method of Pupation. Turning to the different methods employed in the formation of puparia, a few brief general remarks are all that are necessary. I notice in the first place that digging at the roots of trees for pupae is not only extremely arduous work, but that so far as Para is concerned it is next to useless, as the larvae of almost all species wander some distance on the ground and can seldom be traced. Many are subterranean, and, judging from their habits in captivity, do not hesitate to burrow deep into the earth to form their puparia in a loam that is sufficiently plastic to enable them to dispense with silk in the construction. So far as my experience goes, the entire subfamilies Acherontiinae, Ambulicinae, and Philarnpelinae behave in this way. In Choerocampinae the method is different, the larvae of Xylophanes never really entering the earth, but pupating at some distance from the food-plant on the surface of the soil, and being simply protected by scraps of growing or dead vegetation spun together by a few strands of strong glutinous silk to form a covering. It is in the subfamily Sesiinae that we see the greatest divergence in the method of pupation. All the species can, I imagine, produce silk, and some actually do produce a considerable quantity to form their cocoons. In Oryba, Epistor, Perigonia, and Sesia subterranean methods are adopted, and the quantity of silk is negligible. In Pachylia, Erinnyis, Pseudosphinx, Leucorhampha, Enyo, and Aleuron the species pupate in a loosely-spun cocoon formed on the surface of the earth among dead leaves and the roots of grass, etc. ; while in Isognathus and Madoryx, though it be but a matter of degree, a very considerable and completely closed-up cocoon is spun, not infrequently in the crevice of a tree- 352 Novitates Zoolooicae XXVII. 1920. trunk or on rotten wood, any particles of debris within reach being used, as we should expect, to stiffen the web and render it inconspicuous. (4) Form, Design, and Colour oj Pupae. Referring to the pupae themselves, I can but once again go through the list and indicate the standard types, showing the lines on which species or genera vary from one another. In general, however, it is worthy of note that all the subterranean pupae, be they black, red-brown, or light mahogany in colour, are nearly uniform in tint and devoid of external ornament; whereas those species which spin cocoons, and remain more or less exposed to the light, are in most cases adorned with a freckled or linear arrangement of markings. The exceptions to this are to be found in such genera as Pachylia and Leucorhampha, where the pupae, though highly lustrous, are of a uniform light or dark brown, and Madoryx, where they are of a dead black, relieved by bands of ochre-yellow in the interstices of two or three segments. In Acherontiinae all the pupae vary slightly between a dark vinous and a yellowish brown, and are more or less glazed. Besides the cremaster, already referred to as possessing highly important, even if minute, specific characters, there is also throughout this entire subfamily the free but immobile proboscis-sheath, providing further good differentiating features between the species by the peculiarities of its lateral ridges and its curve, as well as its length and thickness ; but I am bound to acknowledge that this difference is exceedingly slight between some of the species of Protoparce. In Herse the sheath makes a double turn and is readily distinguished from all others. In Gocytius it is various, being a single but stout and well-protruded loop in antaeus and duponchel, while cluentius possesses a complete spiral like a small clock-spring or Ionic volute, owing to its greater length. It has been a surprise and regret to me that after so long a time in the district I have been unable to trace the early stages of htcifer and the rarer species beelzebuth and Amphimoea walkeri, and can therefore say nothing with certainty about their larvae or pupae. A large dried pupa in the Tring Museum, possessing a big single-loop proboscis-sheath, Dr. Jordan thinks can be referred to no other species than A. walkeri, but the data are absent. With the afore-mentioned genus Protoparce the sheath assumes a big bold curve in rustica and perplexa, is ample but more slender in sexta, diffissa, hannibal, and mossi, shorter but stouter in albiplaga and lichenea. In the genera Eury glottis, Hyloicus, and Neogene, so far as my experience goes, though none are found in Para, this sheath is simply a small turned-down piece lying in juxtaposition to the abdominal cases, as in the common Privet and Pine Hawks of Europe. The plain light brown chrysalis-form, more or less elegantly curved, without free proboscis-sheath and differentiated by many slight variations — such as the precise tone of colour and degree of glaze — is shared by many species in common belonging to the three central subfamilies. Such features characterize Pro- tambulyx, Pachylia, Oryba, and Pholus ; while Madoryx, Leucorhampha, Epistor, Perigonia, Sesia, etc., approximate to one another in darker hues. On the other hand, a certain standard pattern is adopted by Isognathus, Erinnyis, Grammodia, Enyo, and Aleuron, where the ground-colour varies between a Novitates Zooloqioae XXVII. 1920. 353 reddish yellow and a light straw yellow, and the entire surface, which is highly glazed, is more or less heavily adorned with tar-black lines and spots. In Xylophanes an absolutely distinct type prevails in an elegantly-shaped but generally not very lustrous bone-coloured chrysalis, possessing a fine black line down the front to delineate the proboscis-case, an interrupted rnedio-dorsal line in black or brown, big black spots enclosing the spiracles which are of a dull red, while the rest of the surface is freckled by light umber patches and finely-pencilled lines and dots of a deeper hue. We have already stated that the cremaster stands first and foremost as a distinguishing character ; and as with the variations exhibited in the tails or horns of the larvae, so here a complete enlarged diagrammatic representation of the cremasters of all Sphingidae for comparison, group by group, is a decided want, and would form an adjunct to the evolutionary study of the family of the highest importance. Speaking generally, however, for a moment, and by way of leading up to the last phase of the subject with which I wish to deal, and which I trust will be found by no means the least important or the least interesting, I must first make reference to such items in my collection where I am still in the dark as regards their early stages. Some few of these have occurred singly and rarely as moths, and, providing no clue, have defied all my repeated attempts to investigate their origins. A few others have only been taken once or twice in the larval condition and subsequently bred. Some have been chance finds, in the first instances at any rate, while others have only been found after diligent and prolonged searching, and by testing to the fullest extent possible every hint which the first discovery seemed to suggest in regard to food-plant and locality. This has involved an increasing acquaintance with the botany of the district, and in this department I have at all times received most valuable information from the enlightened authorities of our local Museum and Botanic Gardens. I refer to Mr. F. Ducke, Miss Snethlage, and the late Dr. Huber, — a botanist of world-renown, whose untimely death through appendicitis in 1913 was a deplorable loss to the science, and whose skilled aid, in conjunction with that of the afore-mentioned friends, has to me been invaluable as an introduction to this vast study. The Flora Brasiliensis, an extensive series of volumes, but still largely incomplete, especially as regards Para, has also at times been useful. Finally, the authorities of the Botanical Department at South Kensington have on several occasions, when consulted, been most kind in rendering expert advice in the matter of identification. To one and all I am greatly indebted. It has perhaps given us all some extra work, but it has not been labour wasted, for by the mutual interchange of thoughts, ideas, and information on any given subject related to one's own particular study, knowledge has been disseminated, and our conceptions as individuals in our own lines of research have been broadened and amplified. Not infrequently also has the co-ordination of scientific facts in the realms of botany and entomology, which in their interdependence run on marvellously parallel lines, led to a happy readjustment of ideas that aforetime were hazy, and to the correction of positive errors. Hardly less important has been the marking of certain exact spots in the great border-line of knowledge which man has not yet passed, but which with time and patience, " by mutual sympathy 354 NOVITATES ZOOLOGICAE XXVII. 1920. and mutual aid," he assuredly can encompass. I refer, for example, to quite a number of plants and insects which are still unknown to science, and conse- quently as yet possess no specific names, though their genera may be obvious. I refer also to a perfect host of lepidoptera, where some species are still waiting for a name and an approximately correct family status, and where anything like a full and complete system of classification, whatever else may count, must comprise some elementary acquaintance with early stages. In Europe, where so much has been done, and where the material is so meagre by comparison with the tropics of America, we are apt to imagine that if only we go about the matter in the right way, some one can surely be found who will be able to tell us all about the butterflies and moths of the latter continent. Nothing could be further from the truth ; and yet it was some such idea that I myself entertained before I went out to Peru in 1907 and found that in this, as in other matters, there was no high-road to knowledge, no pleasant hand-books of botany and. entomology, and no collector's guide to the district. What one does find is the wealth of Nature's resources which baffle description, coupled with an array of unforeseen difficulties and drawbacks which equally thwart one in the endeavour to wrest from her more than a mere tithe of her secrets. While making due allowance for all the splendid scholarly works on insects in general, and especially for those on particular groups and families, that have yet been published, the fact remains that the early stages of very many species of Lepidoptera, including some of the most beautiful forms in the natural creation, some of the most curious, some of the most grotesque in their marvellous adapta- tion to environment, are still, in the great majority of instances, unknown to science. If you have a collection of exotic Lepidoptera you may, by visiting one or other of the standard collections of the world, experience but little difficulty in getting most of your specimens named with a correct Latin designation as to family, subfamily, genus, and species, and you may also learn much as to the range of distribution which any particular species enjoys. But when it comes to the question of early stages, with even the most willing and enlightened of informants, there is often no one who can tell you in a thousand instances what the caterpillar looked like, what it fed upon, whether there was anything beyond the ordinary in its method of pupation or the egg-laying of its mother, or indeed anything at all about its habits as a living organism. Herein to me lies the intense interest of the quest, but when all this is unknown more than half the interest of a collection of moths vanishes. Having collected now for more than thirty years, with an ever-increasing enthusiasm as experience became enlarged, I have come more and more to regard a big collection with feelings akin to dismay. Though it be the outward and visible result of years of patient toil, in itself, and apart from other considerations, it can impart such limited information about that great world of life which lies behind it. The collection, without doubt, is highly necessary and important as a library of reference, case after case is very beautiful, a species here and there and now and again a whole genus exceptionally so, while another set are dull and monotonously alike to the untrained eye. But whether showy or plain, the fact looms larger than it once did that it is a cemetery of corpses, more or less well-embalmed and preserved, and, if well- ordered, possessing a number of interesting memorial tablets and epitaphs ! The mournfulness of the spectacle is of course considerably diminished and the Novitates Zoolooicae XXVII. 1920. 355 interest sustained when whole families are entombed together under glass to facilitate the study of the comparative anatomy of their mummied remains, and especially when the epitaphs are generous enough to afford not only the name but the birth-place and date of decease ! Lest, however, I should shock any orthodox mind by such profane sentiments, let me at once call myself to order with an apology for my tangential wanderings and for discoursing at such length, and let me proceed to give some of those touches from the life, with which, at any rate, no one can quarrel, however much he may deplore the limitation of such information as is now available. (5) Sphingid Larvae and their Food-plants. We come then, finally, to a phase of the subject which has long appeared to me to be one of intense interest and importance — namely, Sphingid larvae and their means of sustenance. In a land that is nearly all forest, where the vegetation is rife and luxuriant, where in hundreds of cases one tree bears the strongest outward resemblance to another, but where, nevertheless, the range of absolutely distinct species in particular localities is in reality so great as seemingly to equal the number of individual items of plant life which greet the vision, it is not unnatural to inquire how is one in such a labyrinth of green to find out the names of particular species. How indeed, unless sooner or later one can come into touch with some very experienced informant ! But in truth, the finding of a name, the necessary symbol of communication though it be, is not the first point in order of importance. What I mean to emphasize by saying this is the paramount importance of first adjusting the eye to those nice shades of difference in plant-life which distinguish closely-allied species, and, still more important, species not at all allied but belonging to different Orders, and bearing often an extraordinary superficial resemblance to one another. The bewildering tangle of growth which characterizes the Amazonian forest not unnaturally tends to obscure its less prominent details ; and it is only after weeks, perhaps months, of experience in the same locality, that one is able to form some rough mental classification, and focus one's eyes upon individual objects. Then with the observation-faculties intensified, one learns by degrees to be less led by appearances, and to appraise at their true worth those characteristics which are more fundamental and which bind together in one great Natural Order many forms outwardly dissimilar. The specially-favoured locality selected by different trees and plants also calls for attention, be it the humidity and shade of overhanging matto-growth with its rich soil of decayed vegetation, or the region specialized by tabatinga clay or white sand, the sun-scorched dry and open " campo," the " capoeira " or simple woodland, the " igapo " or forest swamp, or the land to a greater or less extent under cultivation with its fruit-bearing trees, each special in itself, and each with a varied and specialized flora and fauna attached. In fact, to put the matter shortly, an abundance of quiet field-work with the closest observation of almost everything is undoubtedly the first requisite. Then it is time to secure a few names, if these have not already been obtained ; and if the species, and perhaps the genus too, cannot readily be identified, one ia seldom so out of luck's way as not to learn at least the Natural Order, which, 356 NOVITATES ZOOLOGIOAE XXVII. 1920. as I shall endeavour to show, is often the most valuable of the three, and ought always to be recorded when possible. On procuring some desirable caterpillar, my plan is generally to take it home in a tin with a sufficient amount of its special plant to serve as food, and also a good sample-specimen to dry and preserve for future identification, not forgetting to note down its association with that particular larva. One speedily learns that it is often not possible thus to identify the plant without its flower, so this too should be sought for, though it is sometimes tiring and disappointing work. Further discoveries reveal the same larva, it may be, upon a number of distinct species which ultim- ately prove to belong to the same Order, or to one in the same general group of plants. The recognition of this alliance in the plant-world next offers a clue which, if followed up, not infrequently leads to the discovery of an allied caterpillar upon a kindred plant, and little by little one learns, for example, that an entire lepidopterous genus is associated with some particular genus of plants, or is at least confined to the group. Equally worthy of note is it that allied genera in the same lepidopterous subfamily are in frequent instances similarly restricted to one and the same Natural Order of plant-life. The last point in this connection is no less striking — namely, that an occasional instance occurs where an Order like Vitaceae, or possibly a single genus of that Order like Cissus, or the common grape-vine itself, will serve as a pabulum for species so distinct as to represent no fewer than three different subfamilies like Sesiinae, Philampelinae, and Choerocampinae, though this of course is very exceptional. The result of all these revelations has been to emphasize in my mind the great importance of the Natural Order, to give it always in this connection the place of precedence over generic or specific distinctions, and to work for the discovery of the larvae of those species which still remain unknown largely upon the analogous principle that they will probably some day be found to be associated with some plant or plants closely akin to those already known as the food-plants of kindred species in the lepidopterous world. I will give three examples in application : (1) Seeing that three species of Cocytius in nature feed on at least six species of Anonaceae, and perhaps a great many more, it is highly probable that the remaining two in Para, together with the closely-allied Amphimoea walkeri, are also Anonaceous feeders. Up to the present, however, this species with Cocytius lucifer and beelzebuth have only occurred as moths, and I have to confess my inability to trace their larvae. (2) In Para we have three species of Protambulyx and three of Amplypterus, and the whole six appear to be closely allied to one another. By exploring the caju tree, Anacardium occidentale, and the taperiba, Spondias lutea, and at least three other wild species belonging to this same Order Anacardiaceae, I have very often come across larvae sufficiently varied to convince me that I had secured different species, and as often have I been doomed to disappointment by breeding nothing but typical P. strigiiis. By continuing, however, to work on this principle, I have at last succeeded in finding the larva of P. eurycles on an Anacardiaceous tree like the ash, locally known as " tapiririca." The moth is common enough to leave me still wondering why its larva does not turn up more frequently, while as for P. goeldii and the genus Amplypterus I am yet no further advanced. (3) Out of 12 species of Xylophanes in Para I have taken the larvae of 7, NOTITATEa Zoolooicab XXVII. 1920. 357 and, though two can feed on plants of distinct Orders, all but one in nature have been found associated with Rubiaceae — such as Spermacoce, Palicourea, Psychotria, etc. There is, therefore, a fair presumption at least that all the remainder are Rubiaceous feeders, and that in proportion as the alliance between any two or more is close, so are their larvae likely to be found feeding on these same plants or on species close akin. Perhaps the most striking exception to the general rule is to be found in Protoparce, which as a genus is commonly associated with Solanaceae, but where albiplaga seems to be limited to Boraginaceae and Anonaceae, the latter seeming to suggest a connection with Cocytius, which is extremely interesting. P. lichenea I have only taken on Citharexylutn, a Verbenaceous plant, while the common rustica associates itself with many plants in Verbenaceae, Boraginaceae, Bignoniaceae, and Oleaceae, but never with Solanaceae. Among the remainder of my acquaintance P. sexta, hannibal, and the rare perplexa are occasionally seen to be sustained in nature by two or three species of Aegiphila, another Verbenaceous genus, in place of their more customary Solanaceous plants. In the Andes of Peru I found the larvae of Euryglottis davidianus associated with Boraginaceae and Bignoniaceae, and as Euryglottis comes next in order to Protoparce it is highly instructive, providing a wealth of suggestion to the explorer, to learn that botanists group Boraginaceae, Bignoniaceae, Verbenaceae, and Solanaceae together in the series Bicarpellatae of the Gamopetalae. So once again our exception hardly does more than prove the rule. One is naturally led to suppose that there are important ingredients in the chemical composition of the leaf which are shared alike by all these plants, though so seemingly diverse in form, and that this nutritious principle is essential to the life not only of Protoparce, but of other species of other genera in Acherontiinae. Here, surely, is the evidence of design, to be accounted for as Darwin did by some grand evolutionary modifications in both plant and insect, running on parallel lines and reaching back into the remote ages of the past. Coming to present times, however, and allowing for the exceptions which greatly increase the number of those Natural Orders selected to provide food for Sphingid larvae, it is a striking and significant fact, and one which came to me as a revelation of analysis, that of the 63 Para Sphingidae whose early stages have been revealed, leaving at least another 27 where they have not, no fewer than 17 are associated in nature with Apocynaceae, 14 with Rubiaceae, 8 with Vitaceae, 7 with the gamopetalous Bicarpellatae, and the remainder as follows : Dilleniaceae 4, Anonaceae 4, Moraceae 3, Onagraceae, Euphorbiaceae, Papayaceae, Anacardiaceae, and Asclepiadaceae 2 each ; Convolvulaceae, Piperaceae, Sapotaceae, Polygonaceae, Melastornaceae, Loganiaceae, and Vochysiaceae 1 each. Though I have occasion to refer to several other species of Sphingidae beyond the above 90, I naturally exclude them from my Para statistics. They form, as it were, a supplement, too small to stand by themselves, and too in- teresting to be ignored simply because they happened to live, one of them at Pernambuco, one in the Antilles, one at Iquitos, and three others anywhere from 500 to 1,000 miles up the Amazon. In conclusion I may say that, with the Sphingidae as one of my keenest specialities for a long period, I have striven to gather together every scrap of possible information relating to the life-histories of such species as have come under my notice. With this then, for the present, I must ask my readers to 358 Novitates Zoolooicae XXVII. 1920. be content, and wait in hope for that day when errors shall be corrected and a few more gaps filled. Paha, January 1919. GENERAL CONDITIONS. Under this heading I have briefly sketched a number of more or less dis- jointed facts and figures, which may enable the reader more readily to picture Para and appreciate its advantages and disadvantages as an entomological centre. Such notes are often of considerable use to the practical collector. Belem (Para), with a population of about 120,000, is the capital of Para, the third largest State in Brazil, and is situated 1° 27' south latitude by 48° 30' west longitude. Though nominally at the mouth of the Amazon, a glance at a large-scale map will show that the main bulk of Amazon water reaches the sea north of the great delta island of Marajo, whereas Para stands near the confluence of a distinct river-system, the immense Rio Tocantins proceeding from South Brazil, the Moju, the Acara, the Capim, the Guama, and the Guajara. All these rivers are tidal and, with the exception of the Tocantins, very muddy, the rise and fall being 8 feet for neap tides and over 12 for spring tides. The general elevation above sea-level is only a few feet, the highest part of the city being about 40 feet. Pictorial Aspect. — Faced on west and south by Ilha das Oncas and innumer- able other islands, which partake of much the same character as the swampy part of the mainland. Backed closely on other sides by unlimited matto, an impenetrable jungle of virgin forest growth. Immediate south-east and east largely igapo or swamp region, practically impassable, even in the paths cut by seringueiros (rubber gatherers), after heavy rain or high tides. Railway cuttings through the matto run north to Pinheiro, passing through a tract of very white sand with a modified vegetation at kilometre 11, and in a north- easterly direction to Braganca. Roads leading from the city among the palm- thatched and humble dwellings of the caboclos (people of more or less Indian origin), towards the rivers or the forest, are known as travessas. These include many small fruit-gardens which generally abut on second-growth forest. Most of the travessas are broad, are cut at regular intervals, and are intersected by others on the rectangular block principle. They are the streets of a larger city in the making, but are still covered with grass and weeds like Spermacoce, etc., some being used for pasturage, and parts of some being distinctly swampy. The forest is divided by a network of igarapes (small tributary streams), the majority being muddy and subject to the rise and fall of tide, while a few are peat-coloured and clear with sandy bottoms, owing to a slightly increased elevation. Unlike the Isle of Marajo, which possesses broad, open campos for cattle- grazing, our open spaces are very limited in number and extent, and are probably all of artificial origin. The " Bosque," situated outside the city at Marco da Legua, is a decent tract of original matto or forest, about 500 metres square, intersected by shaded paths and adorned with fountains and shelters as a resort for the public. Its conservation represents a degree of good taste and foresight which is somewhat exceptional in this part of the world. The Morphos NOVITATES ZOOLOGICAE XXVII. 1920. 359 and other woodland butterflies are often to be seen here, and not infrequently have I here procured some larva of worth upon the undergrowth, or detected the presence of others altogether beyond my reach in the highest trees by their excrement scattered over the sandy paths. The public prafas, squares, and gardens of the place are characterized by many trees imported from other countries, chief amongst which may be mentioned the Mango and Ficus benjamina as shade-trees in the streets, the banana in all its forms, and a number of oranges and lemons. These, coupled with certain flowering plants, garden palms, and other importations like Artocarpus, the " Jaca " and the bread-fruit tree, etc., naturally tend to produce in the mind of the visitor a completely erroneous impression in regard to the really indigenous flora of this part of Brazil. Owing to the kindness of Miss Dr. Snethlage and of Sr. Rudolpho Siqueira Rodrigues of the Museu Goeldi, I am enabled to give some interesting statistics in regard to the climatic conditions of Para for the past eight years, 1911 to 1918 inclusive. Bainfall. Temperature (Centigrade). Hygrometer (per cent.). Millimetres. Days of rain. Maximum. Minimum. Medium. 1911 88 2,550-2 272 33-6 21-4 25-4 1912 86 2,918-3 323 33-4 21-9 25-3 1913 88 2,616-8 280 33-6 21-6 25-5 1914 88 2,299-6 252 34-6 21-4 25-6 1915 89 2,042-3 215 34-6 21-7 26-3 1916 89 2,638-4 218 32-9 221 25-6 1917 89 2,809-7 248 320 220 25-8 1918 89 2,541-6 238 21-4 = 26- 1 = Fahren heit 90-7 70-5 790 The above figures indicate that in relation to its proximity to the equator, Para possesses a remarkably high degree of atmospheric humidity, frequently reaching' a state of absolute saturation, and as a direct consequence an excep- tionally moderate and uniform temperature. This is roughly 80° Farenheit in the shade of one's living-apartments throughout the year. The wet season normally begins during the second half of December and ends with May. The hottest month is nearly always November, the wettest February or March, and the coolest period from July to October inclusive. In 1916 and 1917, however, July was an exceptionally hot month, as was the close of August in 1918. The wet season is accompanied by much thunder and lightning and by many very heavy, but only occasionally prolonged, falls of rain. It is to be noted that even during the dry season there is seldom a week or ten days without any rain, but that then the rains are more regular to time of day and of short duration. The result is perennial green and a vegetation which seldom hangs limp. Though times have changed considerably since the days when Dr. Alfred Russel Wallace and Mr. Bates spent their six months in Para, living near the village church of Nazareth in a wooden hut at the delightful price of 30 milreis a month, and though the population has probably trebled since then, there are still a few ancient landmarks. The Nazareth Praca, for example, is still there, 360 Novitates Zoolooicae XXVII. 1920. but is now, of course, a definite part of the city, surrounded on all sides by houses. The church of their day has long been replaced by a larger edifice, close to which I myself lived for some months. This is still so popularly attended that it is now giving way once again to a more spacious building of very greatly improved solidity and architectural form. The famous Nazareth Festa, though degenerate in its cheap-jack association and modern cinema shows, is still the great feature of the place every year as October comes round ; we still drink purple " assahy " with or without " farinha " ; and still, most assuredly to an increased extent, have our nerves shattered by innumerable rockets, fired off at the slightest pretext at all hours of day and night. The old city of Belem, with its fine cathedral and castello, can have changed but little in outward appearance since 1848 ; but though the chief markets are still at Veropeso, the centre of the city, territorially speaking, is to-day marked by the Largo da Polvora, the Theatro, Cafe da Paz, and Grand Hotel, the last two providing excellent accommodation for visitors. Close to this, and leading towards the beautiful Largo de Baptista Campos, in former days all wild matto, is the ancient British cemetery, dating from 1815, where, through the generosity of English banks, business houses, and especially Messrs. Booth & Co., I was enabled in 1912 to build a small English church. The old mud-stretches of the Para river fronting the city have now, with the exception of the Veropeso dock, all been mercifully buried beneath many thousand tons of clean sand, a factor which has contributed largely, not only to the appearance, but to the health of the place, not one case of yellow fever, so far as I am aware, having originated here since the early months of 1911. A bad name dies hard, and at this late date it is really surprising to find so many persons of education who know nothing of Para's charms, and who merely regard it as a mud-stretch and a death-trap to the white man. Though hot and lacking the salt sea-breezes of towns on the coast, there is probably no pleasanter or more comfortable place in the north of Brazil than Para, none so up-to-date, and none that is freer of fevers and epidemics. As in other parts, there is, of course, the ever-present malaria of the tropics, but it constitutes no serious menace to Europeans passing through or settled in the city. Camping out in the forest without a mosquito-net is of course to be avoided ; but with some such preventitive, which is always a comfort whether in town or country, there is really nothing to be feared. The rickety wooden trapiches or piers of former days have now been replaced by a stout wharf of concrete, upon which stand a number of great corrugated- iron sheds. Alongside these lie tethered not only river boats but ocean liners with a draught of 20 feet or more, which continue their journey for a thousand miles up-river to Manaos. Boats drawing from 16 to 18 feet of water proceed to Iquitos in Peru, no less than 2,200 miles from the Atlantic, so immense in breadth and depth, as well as in length, is this South American Mediterranean. Finally, Para is to-day magnificently served throughout by an adequate supply of speedy electric cars, called " bonds," not to mention the ubiquitous automobile, 300 of them at least; and the well-built houses and well-paved streets, which in the main are distinctly above the South American average, are brilliantly illuminated by electricity. Novitates Zooloqioae XXVII. 1920. 361 NOTES ON THE SPECIES. Having already dealt at considerable length with so many general questions touching not only the characteristics of genera but the individuality of species, repetition would be superfluous ; and as some of these species are common and well known, my notes on them can well afford to be brief and scrappy, and must be regarded as merely supplementary to what has gone before. The Detail Index, which comes later, provides, so far as I have found it possible, the full list of local food-plants with their localized popular names, if any ; but I have refrained, as inconsistent with the title of the present work, from intro- ducing the names of those particular plants which serve the species in regions remote, but which either do not grow in Para, or are seldom, if ever, selected as the natural food-supply in this part of the world. For descriptions of the moths, their general range of distribution, as also their subspecific or geographical differences, matters which do not come within the scope of my treatise, I must in all cases refer my readers to the work by Lord Rothschild and Dr. Jordan, entitled " A Revision of the Lepidopterous Family Sphingidae," issued as a Supplement to Vol. IX. of the Novitates Zoologicae of Tring, England, in 1903. The species are here numbered according to the Catalogue. T.Z.8. is an abbreviation for Transactions of Zoological Society, London, vol. xx. pt. 2, and refers to Plates in Sphingidae of Peru. N.B. — Larvae are described throughout as possessing 13 segments, the head, for uniformity's sake, counting as No. 1, the leg or thoracic segments being Nos. 2, 3, and 4, the post-thoracic segments 5 and 6, the clasper segments 7, 8, 9, and 10, the tail or horn being situated on the back of 12, and the anal flap and claspers constituting segment 13. Subfamily ACHERONTIINAE . 4. Herse cingulata. (Plates T.Z.S.) R. & J. p. 10. Larva secretive in habits and seldom met with except by systematic searching. In colour, markings, and form up to fourth moult resembles Protoparce with a straight horn. In final stage very different, possessing curved horn and usually more brown than green, but widely variable. Moth common at light in Para, but I have not observed it at flowers like II. convolvuli in Europe. 33. Cocytius cluentius. (Plates 1 & 2.) R. & J. p. 54. A common species in Para, the moth in both sexes often appearing at electric arc lamps. Larva twice found feeding on Piper aduncum, a seemingly strange departure from the customary Anonaceae, Biribd, Oraviola, Araticu, etc. ; a somewhat pronounced aromatic odour being the only apparent feature in common between the two Orders. Young larva dull sage-green and white, side-strijies irregular in length and 362 NOVITATES ZOOLOGICAE XXVII. 1920. breadth, and merging into the medio-dorsal band in a series of Vs. Fourth instar with fine, light, and scattered hairs, and minute yellow tubercles on thoracic segments, especially segment 2. A couple of broad and composite bands, which are conspicuous by their nebulous whiteness and great length, spring from the base of the post-thoracic segments, with three others in rapidly diminishing ratio in front, and all merge in narrow V-formation into the white medio-dorsal line. Three others, very faintly indicated on a deep green ground, represent the customary fourth, fifth, and sixth side-stripes, while the seventh leading up to the horn is once more marked by a nebulous white band which stands out conspicuously, but melts away into a bluish ground. Horn emerald and glazed with small yellow setiferous tubercles. Anal portion dull blue, but flap brightly edged with yellow-green. In adult stage uniformly hairy like antaeus, but always very white. Description in R. & J. correct but deficient. Pupa, like all in Acherontiinae, subterranean and bright mahogany in colour. The proboscis- sheath is so long that it makes as much as 2\ concentric turns in the form of an Ionic volute. Length of proboscis very variable : in female moth &\ to 10} in., in male 10} in. 34. Cocytius beelzebuth. R. & J. p. 55. My remarks below on the occurrence of C. lucifer and the uncertainty of its appearance apply equally here, except that I can say even less of this rare species, having only captured the moth at light in Para on three occasions, once in 1911 and twice in 1912, a female on July 4 and a male on the following day, both in perfect condition. 35. Cocytius duponchel. (Plate 1.) R. & J. p. 56. Undoubtedly the commonest species of the genus in Para, both sexes occurring freely at light. Larva without any of the short hair which forms such a pronounced feature in cluentius and antaeus. Side-stripes, except the third and seventh which are white, but faintly delineated in all instars. Intensity of colour, as with many green larvae, variable in individual specimens, and generally well matched to the particular variety of food-plant selected. Markings more intense when ground colour inclines to yellow-green, fainter when com- pounded or combined with white-green. Proboscis-sheath of pupa, though stout, well-curved, and much swollen at the extremity, is nevertheless distinctly shorter than that of antaeus. The male moth possesses a very strong, musty, and disagreeable odour, akin to that of the cockroach. This is shared somewhat by other Sphingids and by some Liniacodids, but generally to a less noticeable extent. Length of proboscis in female moth 3 J in., in male 3} in. 36. Cocytius antaeus medor. (Plates T.Z.8.) R. & J. p. 57. Moth in both sexes common at light in Para. Food-plants, as in the last species, exclusively Anonaceae. Rounded head of young larva becomes extremely NOVITATE3 Zoolooicae XXVII. 1920. 363 arched or pointed on the crown, as in Protambulyx, but recovers some rotundity in the final instar. In all stages, and in the three species with which I am acquainted, the larvae are wont to repose geometer-wise, the forepart hanging free from stem or leaf, with two or even three pairs of claspers tucked up and unused. When disturbed it wags itself violently and repeatedly from side to side, another character which it shares to a pronounced degree with Protambulyx. Different to those found in Lima, Peru, the full-grown larva here, as in Manaos and Per- nambuco, is of a very intense uniform green with the side-stripes hardly visible, except the elongated seventh which is very white. The mauve medio-dorsal band is also less pronounced and less edged with white. The pupa, like some others, is endowed with much nervous agility, and the force of the exhalation from its big thoracic spiracles is sufficient to blow away some of the fine sand on which it lies, forming a slight cavity at this point. This is but a recent observation, and it came with surprise ; for though I have experienced various audible sounds from different pupae, it had never occurred to me that a chrysalis could produce an appreciable puff of wind.

From its comparative abundance in Para as a moth at light on July 8th, and from then till October 1912, its return from March to May in 1916, and its spasmodic recurrence since, I suggest that it may be an immigrant from afar, as all attempts to trace its larva locally among Arvonaceae and other Orders have so far failed. The entire genus are obviously long and strong fliers, but, whether in fresh or worn condition, I think I am not beyond the mark when I say that most specimens of lucifer, beelzebuth, and A. walkeri have, in support of the idea, been picked up off the pavement in a somewhat lethargic or tired condition. A strange feature to record, unique among the Sphingidae, so far as I know, and in striking contrast with others of this genus, is that the female of C. lucifer in Para is almost invariably smaller in wing-expanse and less robust in general appearance than the male. Length of proboscis in female moth 4£ in., in the male 3 J in. 38. Amphimoea walkeri. R. & J. p. 61. Here I have once again to refer to my remarks on G. lucifer, and suggest that this large and handsome moth may be drawn from some distance to the electric lights of Para, where alone I have taken it, about a dozen specimens in both sexes from March to October 1912, several times since, and generally in perfect condition. I know also of one specimen caught in Pernambuco. A general characteristic with many of these big S. American Sphingids, A, walkeri included, is that they can produce a very audible squeak when handled, like that of the Death's Head moth in Europe, and recorded in connection with that species as an almost unique phenomenon. A. walkeri possesses, I believe, the longest insect-proboscis in the world, measuring as much as from 10 to 11 in. 364 NOVITATES ZOOLOGICAE XXVII. 1920. Like the genus Cocytius, to which it bears such obviously close relationship, this almost abnormal development of the trunk, strikingly varied in length with different species, would seem to indicate that this entire group of moths are wont to suck honey from flowers with long narrow calices like the Datura. This, at any rate, has been suggested by both Darwin and Wallace. It may, however, simply serve the purpose of enabling long-winged and heavy-bodied moths, as in the case of H. convolvuli, to hover more freely over small flowers like the jasmine without damage to their wings. As to the larva and pupa of walkeri, I can but refer to the notes in R. & J. p. 61, which may possibly describe this species, but I cannot but feel sceptical in regard to the name of Jatroplta as its food-plant. I may not have sufficient grounds for saying that I regard it as an unlikely pabulum, but the fact remains that repeated inquiries among the growers of mandioca and macaxeira, coupled with the assiduous searching on my own part of Jatropha (Curcas) and all such Euphorbiaceous plants, has never produced anything beyond the larvae of two of our commonest Hawk-moths, Erinnyis ello and alope. 39. Protoparce sexta paphus. (Plates T.Z.S.) R. & J. p. 67. Abundant in Para as elsewhere. While falling short of a geographical subspecies, both sexes of the moth are here smaller and blacker, when compared with the form frequently taken in Lima and those which I have seen from other places. The larva, too, has a peculiarity here which I have not encountered elsewhere. When the dorsal and lateral areas are of a uniform green tint, it is smooth and devoid of hair ; when it is parti-coloured, that is lighter dorsally above the side-stripes, as when the larva is found feeding on the white woolly leaves of Solarium grandiflorum, the whole surface is often, but not invariably, covered with very fine, light hair. I naturally thought at first that I had obtained two distinct species and figured them both, but I can observe not the slightest difference in the resulting moths, which in several instances, and in both sexes, I have been careful to label " smooth " or " hairy," in accordance with their former larval peculiarity. Both forms are equally common on many Solanaceous plants, and in no other respects that I can see, beyond what has been mentioned, do they differ. If the moth appears commonly at fight, the caterpillars are still more frequently brought to one by friends who find them in their gardens on the capsicum peppers, the " Bringella," the tobacco and tomato plants. Besides several species of Jurubeba and Cestrum floribundum, the larva is also sometimes found feeding in nature on Verbenaceous plants such as Aegiphila cuspidata, data, and probably velutina. Again, I once took it devouring a hair- leaved garden creeper with crimson flowers, locally known as " Prima veira," and which I am told ranks as a Solanaceous plant, though no one beyond its mother-moth or the most erudite of botanists would have guessed it. Length of proboscis in male moth 3J in. 44. Protoparce diffissa tropicalis. R. & J. p. 75. A somewhat scarce species in Para, a few moths only having occurred at light or on tree-trunks. From time to time I have taken solitary larvae, and Novitates Zoologicae XXVII. 1920. 365 always on species of Solarium, 8. campaniforme, the as-yet-unnamed species which serves P. perplexa, another common kind with long, rough, pungent leaves, and perhaps oftener on three of the common Jurubebas. Though obviously distinct as a species, the caterpillar of diffissa bears but few characteristic features to differentiate it from a washed-out example of P. hannibal ; while the moth, especially when worn, may easily be mistaken by the uninitiated for a brown specimen of P. sexta. The Pernambuco form, however, if one may judge from a single specimen seen, is much richer in its combination of black and brown, and would appear to rank as the subspecies difpssa petuniae of Southern Brazil. Confusion between the larvae of diffissa and sexta can at any rate be avoided by remembering that diffissa bears an ample horn which is green and rough and only slightly curved, its head is faintly lined with yellow, and there is no black edging to the seven light side-stripes. Though I once bred the species from a larva taken in the Interior of Peru, my figure in the T.Z.S., Plate S.d, is in error in all these respects, and this particidar specimen, which was found on wild tobacco and figured, can only have been a strongly-marked sexta, while the real diffi.ssa escaped my then undiscriminating eye and its pupa got mixed up in my subsequent travels. In accordance with its close alliance, the pupa is, as one would expect, intermediate between sexta and hannibal, though almost impossible to differentiate with any certainty. The larva is sometimes stung in the region of the spiracles by a dipterous fly similar to that which affects P. mossi in Lima, and it is also attacked by a hymenopterous parasite. 46. Protoparce hannibal. (Plates 1, 2, & 9.) R. & J. p. 78. A fairly common species in Para, occurring at light but never abundantly. Food-plants : Solanaceae, Oestrum floribundum, Solanum campaniforme, and, as stated by Bonninghausen, trombeta or Datura, two garden species being often chosen ; frequently also on Aegiphila data and Clerodendron (Verbenaceae). Though the larva varies in itself, as in its food-plants, with acquaintance it admits of little doubt as to its identity, being generally of a very intense green and almost blue on the ventral area, while the seven oblique stripes are broadened downwards in their whitest portions. The more normal form at any rate is thus readily distinguished from diffissa, and still more from sexta by the absence of any black above the stripes, the presence of a few short yellow tubercles on the thoracic segments, and the ample curved and rough green horn. Pupa similar to both of the preceding species, but in Para bigger than either. Proboscis-sheath rather shorter and more robust. Protoparce perplexa. (Plates 2 & 9.) R. & J. (1910). As far as the moth is concerned I have taken but two worn males at light in 1912. Apparently a very rare species, though, if local, I have reasons for thinking that the Para region is at least one of its strongholds. Food-plants : (1) A delicate arboreal Solanum, sp. ?, with small heart-shaped leaves, which 24 366 NOVITATES ZOOLOOICAE XXVII. 1920. are rough to the touch and light on the under-surface, a widely-distributed plant, seen abundantly at Porto Velho on the Rio Madeira, but growing only sparsely in the shade of the forest near Para. (2) A creeping species of Solanum with bright vermilion berries, rarely noted in the Para matto. (3) Aegiphila cuspidala ( Verbenaceae) ; one larva only. The moth at first might be taken for a richly-marked Amazonian form of scutata, but the larva in all its stages is wonderfully distinct from that species. It was on the first-named plant in early March 1915 that I eventually took a single " stung " egg and a very remarkable large black caterpillar with a bright yellow horn, heavily adorned with setiferous tubercles, held erect and rather sharply curved down at the tip. The thoracic segments were similarly ornamented with a thick cluster of exceptionally tall and sharp-pointed tubercles, three being situated on segment 5, and an odd one marking the right dorsal area of segment 6. The entire ground-colour of the larva was sooty black, only the last four oblique side-stripes being faintly indicated in a lighter key and edged above with an intenser black. The general tone is modified to a gloomy maroon with advancing growth. My impression at the time was that I had secured a strange melanic variety of some species ; but having been fortunate enough to possess this strange caterpillar on eleven subsequent occasions, I find that this description of the final instar holds good in every detail, even to the irregularity in the position of the dorsal tubercles, one specimen having an odd one on segment 8 and an unequal pair on segment 10, surely a unique feature in Protoparce ! Only two of these were found full-grown, and one was full of dipterous maggots. The remainder were taken in the egg or as very young larvae, and these up to the end of the fourth instar were always green, the seven side-stripes gradually increasing in clearness of definition and the colour intensifying to pure white and lemon-yellow, outlined above with olive. The face up to this stage is lined with yellow, and the long, yellow-green horn is always exceptionally erect and is roughened on its upper side with black tubercles. The first larva obtained formed a dark red-brown pupa similar to that of P. rustica, with a long proboscis-sheath, and produced a richly- variegated female moth of perplexa, to my great delight, on April 21st, 1915. After working methodically for this species from the beginning of 1917, I managed in February, from the two species of Solanum, above-named, to secure at least a dozen ova and young larvae, and subsequently lost five through the attack of a small black ant which infests my house. Assiduous searching in 1918, a wretched year for almost everything, produced only one larva in the fourth instar on January 29th, this time a plainer green variety resembling hannibal (see fig.), found feeding on Aegiphila cuspidata, and resulting in a perfect male on March 5th. At the time of writing, February 18th, 1919, we appear to have reached low- water mark, and much searching of the most approved plants in all the likeliest places for miles around Para has yielded nothing but three eggs of this rare species on one small bush, and all of them doomed, black centres of corruption, dead yet strangely living, destined but to render a homage to Baal, the Lord of flies. Written later. — Towards the end of March I found a small bush of Solanum completely eaten down, an abundance of black excrement freshly deposited and typical of this species. The disappointment was great, for I had searched here before, and from former records I judged that for this year, at any rate. Novitates Zoologicae XXVII. 1920. 367 the time had gone by. I persisted, however, in the repeated examination of a particular scraggy Solarium which is still permitted to stretch out its brittle arms towards the sun in one of the shaded but now disused pathways of Utinga, and which had yielded ova in 1917. Here on April 1 1th I was unexpectedly rewarded by finding three oval green eggs on the under-surface of its sparse leaves, which proved to be those of perplexa, recently deposited and unstung, and from which I had the good fortune to rear three perfect moths, a female and two males, before leaving for England on June 11th, 1919. As an exceptionally rare and interesting species, it is perhaps worth while recording the following details of their life-histories : Ova darkened so irregularly from April 17th that it was feared they were stung. About noon on the 19th they hatched satisfactorily into well- formed white larvae with erect black tails. Having consumed their egg-shells, they readily took to fresh leaves of Solarium and Aegiphila, soon becoming green and glossy. Then, having more than doubled in size, they cast their first larval skins after no more than 50 hours. Their subsequent growth was proportionately rapid. On the 30th two of the three larvae performed ecdysis for the final instar. This occurred at 9.30 a.m., and from being of a sombre green with 7 clear white stripes, the entire area gradually darkened, while the yellow of the horn and fleshy tubercles became more intense. At 11.10 a.m., the side-stripes having now become so dark as to be scarcely visible in the prevailing blackness of the ground-colour, both larvae turned round and ate up their skins in the approved fashion ; the third moulting similarly later in the day. On the following day all three were more intensely black and the side-stripes practically obliterated. By May 2nd they were much grown, their distended skins appearing lighter and of a sooty maroon colour, and the side-stripes being once again trace- able. On May 4th at midnight two of the larvae were laving their bodies with spittle prior to pupation and the third had finished feeding, making the whole larval period only a few hours over fifteen days. After burying themselves deep in wet loam in three separate tins, the first two actually pupated in the early hours of May 10th, and produced a perfect pair of moths at 9 in the evening on the 28th of the month. Why the third, a perfect male of rather larger dimensions which emerged three days later, should have developed more slowly is hard to say, seeing that no question of sex was involved. It is, however, the unusual brevity of both larval and pupal periods that is specially worthy of note ; for 39 days 9 hours from the hatching of the egg to the production of the perfect moth in both sexes constitutes, I should imagine, a minimum time record for the genus Protoparce. Length of proboscis in female moth 4 in., in male 4| in. 55. Protoparce rustica rustica. (Plates 2 & T.Z.S.) R. & J. p. 84. Though by no means rare in Para as a moth at fight, and noted from time to time as a larva feeding on a variety of plants, it appears to be less common than at Lima. This caterpillar is sufficiently varied in itself and in relation to its pabula among the Orders of Verbenaceae, Bignoniaceae, Boraginaceae, etc., to frequently dupe one into the belief that a new species has been obtained. 368 NOVITATES ZOOLOGICAE XXVII. 1920. Though already figured in Peru, I have made new illustrations to portray ap- parently distinct larvae, found feeding at the same time in the Botanic Gardens on two species of Cordia, one being an exotic from Japan and yielding a larva of a very intense green. Both, however, on emergence proved to be typical rustica, and were jjrobably the progeny of the same mother. In this, as in the majority of Protoparce species, the pupal period is usually about a month, but the pupa sometimes " stands over," as it is termed, for five or six months. Certain obvious advantages as well as disadvantages in adopting this method at once suggest themselves, but the causes which bring it about are far from obvious. Though other species occasionally behave in this way, it is, as one would expect, the exception rather than the rule with Sphingidae in tropical climates like that of Para. Length of proboscis in female moth 4J in., in male 5$ in. 56. Protoparce albiplaga. (Plates 2 & 9.) R. & J. p. 86. Not very common in Para as a moth at light. Larvae found both on Cordia sp. ? (Boraginaceae) and two species of Anonaceae, including the Biribd (Rollinia orthopetala) in gardens. Three specific features call for notice, viz. : (1) The utter dissimilarity of the larva from the ordinary green Protoparce form, albiplaga assuming an uniformly bluish white ground with cadmium lateral patches enclosed by a bold design of black in place of the usual side-stripes. Feeding, as it does, fully exposed on somewhat dull green leaves, no attempt at concealment on the ordinary lines of protective resemblance to surroundings is possible, and it forms a truly remarkable exception to the majority of Protoparce larvae which imitate the green coloration of their leaves, if, as appears, its generic status is beyond question. (2) The disregard for danger exhibited by the larva of this species is still further manifested by the gregarious habit, from three to a dozen or more of the caterpillars being generally found feeding together on the same branch. This is another high peculiarity among Sphingidae, and finds but one parallel in these parts in the case of Pseudosphinx tetrio. (3) The proboscis- sheath of the pupa, which is free like the others, is as stout as that of rustica, well projected in a rounded curve, but barely half the length. 59. Protoparce dalica. R. & J. p. 88. One fine female moth was picked up beneath a lamp in Para and brought to me by a friend on January 11th, 1913. This, I regret to say, has been the beginning and, up to date, the end of my acquaintance with this rare and hand- some species. In such a case, where food-plant and general conditions are not likely to present any special difficulties, one is left to ruminate as to why it should be so rare. 64. Protoparce floristan. (Plates 1 & 2.) R. & J. p. 92. Moth taken on three occasions only at light in Para and cannot be considered common. My first and only larva was one found full-grown on February 22nd, NOVITATES ZOOLOGICAE XXVII. 1920. 369 1916, feeding in the forest shade on a species of Citharexylum (Verbenaceae). This, though green and bearing a general resemblance to rustica, differed in two particulars. The side-stripes and numerous spots were of a pronounced lemon- yellow and the former were unequal, the first three and the seventh being fully twice the width of the remaining three. The thoracic tubercles and thick rough horn were also yellow ; there was no pink or red, and the description given by Burmeister (cf. in R. & J.) is totally incorrect. The pupa differs from rustica and closely resembles albiplaga in its possession of a short, stout, though well-projected, free proboscis-sheath. Emergence in this case was much protracted, the pupal period occupying 4 £ months, and causing me much anxiety during a pleasant stay with Mr. B. Preston Clark in Boston. Despite the cold, however, a perfect male moth put in its appearance on board the New York when nearing Liverpool, and emerged in my cabin after midnight on June 18th. Protoparce vestalis. Jord., Nov. Zool. xxiv. p. 59 (1917). Two extremely fine males .of this new and interesting species were captured on lamp-posts in Para on May 6th and June 13th, 1912, and necessitated a climb on each occasion. By comparison at Tring they are obviously distinct, being larger than floristan and of a more snowy-white character with a more defined pattern, and reminding one of the coloration of the Barn-owl. I naturally hope to come across the species again, but as yet remain as much in the dark as the rest of human-kind regarding the moth and its early stages. It is not unreasonable, perhaps, to associate it with Verbenaceae, but this, after all, is a somewhat " tall order." I may mention, however, that on an imported Verbenaceous bush, known as " Pao de Angola," growing in a garden here, I took a full-grown larva of rustica on February 14th, 1919; whereupon the lady of the house informed me that but a fortnight previously she had found and killed half a dozen other caterpillars which were eating her bush to pieces. These, she said, were of similar size and form, possessing a tail, and, though green in ground-colour, were different in that they had yellow bands edged with black. If correct in her description, they cannot have been either rustica or lichenea ; and I cannot but fear that this dire calamity must have fallen upon heads no less worthy than those of vestalis or dalica ! She and the gardener promise not to do it again, cuttings of the plant have been taken, and, so far as life and opportunity afford, the scent will be followed up. We append here the description of the larva of a species observed at Pernambuco. 88. Neogene dynaeus. (Plate 9.) R. & J. p. 114. For many miles round the city of Pernambuco, on waste ground, in fields and meadows and at road-sides, grows a sticky green Verbenaceous herb which is found useful in dispersing fleas in the neighbourhood of dogs and hens, and is universally known as "meladinha." This proves to be the natural food-supply of the above species, which, it 370 NOVITATES ZOOLOGIOAE XXVII. 1920. Subfamily AMBULICINAE. 137. Protambulyx eurycles. (Plate 10.) R. & J. p. 175. Though a plentiful moth in both sexes at light in Para, and occasionally found at rest by day among foliage, I have only too little to record of its life- history, having but once, after diligent and repeated searching of Anacardiaceous trees, discovered a full-grown larva on " tapiririca." As P. strigilis occurs so frequently and over such a wide area, feeding on " Cajii " and several different species of Spondias, etc., and has at least three dis- tinct larval varieties apart from the type, I had several times previously become convinced that I had at last secured eurycles or its rarer congener goeldii. These were always figured anew, but always produced typical strigilis. Seeing that the moth is so often seen on lamp-posts, it is both surprising and disappointing not to have taken more larvae. I have likewise failed, after repeated attempts, to induce this species or any other Para Sphingid to lay eggs, though provided with refreshment, appropriate foliage, and the run of my gauze-covered bathroom. This species, richer and browner than strigilis, may be described as a little in excess of it in the matter of size. The larva, as one would expect, is very similar, the chief differences noted being that the horn was green rather than blue, and that four of the side-stripes, or what corresponded to them, were broken up into very irregular patches of ochreous yellow on a uniformly green ground of rough texture. The pupae of this subfamily, like the last, are formed in subterranean cavities, probably at some distance from the food-plant. The pupa of eurycles is exactly like that of strigilis, of a warm, glossy brown, long and cylindrical, ample and round in the head-piece, but devoid of any of those peculiarities which characterize Acherontiinae. Length of proboscis in male moth If in. appears, can be taken in any month of the year, and would undoubtedly be a very common moth in the district were it not that its larva is literally decimated by a hymenopterous parasite. There is nothing to indicate the presence of the foe within until the final instar, when the maggots appear and spin small creamy white cocoons all over the moribund form of their victim, standing up on end like tufts of hair. I once took the larva of rustica on this plant, but neither " meladinha " nor dynaeus occur near Para. The larva in nature is generally whitish green with a red mesial line ter- minating in a fine curved black horn. This is supported on either side by a dorsal series of round white spots ringed with black. There are additional black patches, but the extent of these is very variable. With larvae kept in the dark from early days, the black, in successive moultings, frequently increases so much as to prevail over the green as a ground-colour. Though drawn on slightly too robust a scale, four figures were made at full growth to show this variation ; for in the earlier instars, except in the matter of size, there is but little essential change from the form and coloration of the adult. The pupa, like all the rest of this subfamily, is formed in a subterranean cavity. It is light brown, small compared with the larva, and not very elegant in form, and possesses a diminutive lobe turned down on the breast to represent the free proboscis-sheath. Novitates Zoolooicae XXVII. 1920. 371 142. Protambulyx goeldii. R. & J. p. 178. A species accounted rare and local, but recorded from the other side of the continent in Bolivia, and one which I have myself taken in Para on some dozen occasions in 1912-13 and several times since. I also took a moth on the lower Amazon near the Narrows which came to the lights of the boat. The other specimens were all drawn to electric arc lamps in the city ; most of them were in perfect condition, and all but one, a lovely female, were of the opposite sex. A second perfect female was captured at light in April 1919. This species, named after the founder of the Para Museum, is surely the most elegant of all our Para Sphingidae in the perfection of its form and in the bold yet delicate blending of its greens and yellows. It is a matter of considerable regret that I am unable as yet to record anything of its early stages. From its obvious alliance to the adjacent species, it can hardly be other than an Anacardiaceous feeder, and probably possesses a cor- respondingly similar larval form. Length of proboscis in female moth 1| in. 143. Protambulyx strigilis. (Plates 3 & 10.) R. & J. p. 179. A very common species in Para as a moth at light. Larvae also most frequently observed on saplings of " Caju " and " Taperiba " (Anacardiaceae), the denuded stalks or frass on the sand beneath revealing the particular spray where the larva has been feeding, and to which it clings head downwards by two pairs of claspers only, geometer-wise. As with eurycles, the front portion tapers off extremely towards the head, while the claspers on segments 7, 8, and 9, being retractile, are seldom used save when the caterpillar is eating or moving its position. The horn, which is of a light cobalt blue, is well erected and slightly turned up, and it is long and rough but of light construction. The body is generally of a vivid green, well ringed and rough in texture, sprinkled over with fine yellow dots and a series of the same in line to mark the side-stripes. These are less conspicuous than in Protoparce, except the seventh leading up to the horn, which is always an ample white band. Three special varieties of the larva have been noted, the first two at least seeming to depend exclusively upon the particular species of food-plant chosen by the moth. They may be described thus : (1) Utterly devoid of any spots or stripes except the white seventh. This form is invariably and exclusively associated with a fern- like species of Anacardiaceae (genus Rhus), the leaves of which are of a very smooth and glossy green without protruding ribs. I presume that this form of the larva by being similarly plain is the better disguised, but it is little short of miraculous by what process it accomplishes the feat. (2) Green with yellow dots like the type and small inconspicuous blue spiracles, which are constant in all specimens. It differs in possessing a short broad band of pure white outlined with brown, as a remnant of the full stripe-pattern. This is situated immediately above the line of yellow dots on segment 7, and it sometimes possesses a similar band on segment 8. This form, on parallel lines with var. 1, 372 NOVITATES ZOOLOGICAE XXVII. 1920. is similarly restricted to the very crinkled dark green leaves of a somewhat uncommon species of Spondias growing in the Utinga water-works region, and its harmony with the plant is emphasized by the possession of a slightly deeper tone of green. (3) Though the "Cajueiro " or Cachew tree often produces the type, a light pink and yellow form variegated with touches of warm brown is sometimes found on it, seeming to imitate the coppery tint of its newly-expanding leaves. A nervous irritability is a character in common between this species and eurycles, as already noted for Cocytius antaeus, the larva when disturbed wagging itself violently from side to side. The pupa, like the former, is of a warm glossy brown, possessing large eye-cases but no free proboscis-sheath, and outwardly resembles a thin Oryba. Length of proboscis in female moth 1 J in., in male 1 J in. 145. Amplypterus gannascus. R. & J. p. 181. 146. Amplypterus ypsilon. R. & J. p. 182. 147. Amplypterus palmeri. R. & J. p. 183. Here I have so little to say, not yet having had the good fortune of tracing the early stages, that I have perforce to deal with all three species in one short paragraph. Though scarcely abundant in Para, gannascus and palmeri both occur with comparative frequency at the city lamps. Of ypsilon I took a perfect female at light on July 17th, 1912, and this constitutes, I believe, a record for the species in this part of the world. Though there is an abundance of Lauraceas plants in the district, and among them several species of Oreodaphne or Ocotea, the suggested food-plant, and though the moths generally appear in the pink of condition, as if freshly emerged, I have repeatedly failed after many attempts to track any of them to headquarters. When professional collectors on their travels do succeed in rearing a moth from its larva, it is regrettable that they so often pay scant attention to the plant, and are not precise in description nor careful enough, when the opportunity offers, to acquire information as to identity. From the rich herbarium at the South Kensington Museum this is generally to be had for the asking at the hands of the courteous and learned Professor in charge of the Botanical Department, or one of his assistants. This completes my notes on the Ambulicinae for the present. They are decidedly meagre and unsatisfactory, but I have hopes of being yet able to learn something more of the early stages of the Para representatives of this particularly beautiful subfamily. Subfamily SESILNAE. This third great subfamily of the Sphingidae is represented in Para by no fewer than 16 genera and 47 species. Of some 36 of these I now know something about the early stages ; on the remainder my notes for the present must neces- sarily be brief. I must, however, deal at somewhat greater length with Isognathus, and, referring to the close relationship which its species obviously bear to Pseudosphinx tetrio, I would note that the latter differs outwardly from Isognathus Novitates Zoolooicae XXVII. 1920. 373 in three particulars (see R. & J. p. 352) — viz. its greater size, an entire absence of yellow in the moth, and the colour of the pupa, which is red-brown with black lines instead of orange, brilliantly delineated with black, so marked a feature with all the species of Isognatkus, and shared to a less extent by Erinnyis and others. The very obvious alliance between the two genera is emphasized by the following considerations : (1) The common adoption of the various species of Plumicra as food-plant, to which all but three species appear to be restricted in nature. (2) The tendency observable on the part of the larvae of several species of Isognatkus, which is the normal habit of Pseudospkinx, to live gregariously in small numbers. (3) The insistence of a transverse belted design, exhibited in the early instars of at least five species of Isognatkus, and maintained by swuinsoni subsp. ? as well as P. tetrio to the end of the larval period. (4) The strange and somewhat garish arrangement of colours which char- acterize the larvae of both genera. (5) The repetition of a couple of sharp spurs on the anal flap, together with the universal whip-like and flexible black tail, terminating with a minute bifid fork, and more or less clothed with tiny setiferous tubercles. Though I have had the good fortune to trace out the life-histories of all the species yet known except rimosa, and even add a new species or two to the genus, it is apparent that there are obscurities still, and that the present sequential order of the species is wrong throughout. Reverting to the white larva of Protoparce albiplaga with its black and yellow design, considered in relation to the larvae of Pseudospkinx and Isognatkus, may I be allowed to theorize for a moment, and suggest that the colour-scheme of all these larvae, and their tendency towards the gregarious habit, present us with an interesting case of reversion to, or possibly the retention of, ancestral type ? With albiplaga it seems to me possible that, while most of its other structural features have advanced on evolutionary lines exactly parallel to those which have produced its fellow-species, and modified the great majority on the Darwinian principle of Natural Selection, this species and the Isognatkus group, to take prominent examples, have preferred to face danger in the broad light of day with a contempt for duplicity. I may mention that the very young larva of albiplaga bears an extraordinary superficial resemblance to /. swainsoni, being belted white and black with a long curved black tail and a couple of tall black spurs on the anal flap. These spurs appear to be a feature which was once as universal in Spkingidae as the tail, but, while tending to die out, has not yet quite vanished, and is therefore most noteworthy as indicating a common, if distant, ancestry. The importance of this consideration lies in the fact that, while these anal-flap spurs are still so pronounced a feature in Isognatkus and are strongly developed in Protoparce albiplaga, being marked up to the end of its larval period by a couple of reduced black tubercles, the feature is nevertheless obviously shared by such comparatively distant species, but only up to the end of the second instar, as Cocylius duponchel (very slightly in cluentius and antaeus), and even pronouncedly in Protambulyx strigilis. Speaking generally, larvae seem, in some mysterious way which we cannot pretend to delineate, to have been controlled by the obvious advantages and 374 Novitates Zoological XXVII. 1920. extra security gained by resemblance to surroundings ; by being green, for example, and looking like leaves, or brown and resembling twigs and dead leaves, or by hiding away altogether, instead of, as aforetime, as I assume, living in gregarious batches. If the idea be feasible at all, my supposition is that all these species and many others throughout lepidoptera which have adopted or retained " warning colours," seem, as it were, to endorse the principle that, notwithstanding a certain amount of incidental loss and destruction, for them at any rate " honesty is the best policy." Therefore it is that their larvae, being bright and showy, and consequently not much to be desired by the predatory foes of their kind, become an even more formidable spectacle when congregated in numbers. Again, many young Sphingid larvae belonging to different groups show a significant feature in common in the first instar. I refer to the primitive tail, which at this period is long, rough, bilobed and flexible. With the majority this organ becomes speedily modified, but with the Isognathus group, though proportionately enlarged or reduced, it is in its essential features retained to the end of the larval period. In one species, /. swainsoni, so little change takes place that the full-grown larva, a zebra-like white and black creature with a touch of ochreous- yellow, is hardly more than the baby caterpillar magnified. My further supposition therefore is that, in Isognathus as a genus and in swainsoni as a species we have the nearest approximation to ancestral form. This genus accordingly seems admirably placed in Sesiinae, the central subfamily of Sphingidae, for it emphasizes the radial, in preference to the im- possible linear, system of classification. If, however, it should be thought better to instance a large, hardy, and robust Hawk-moth, at once common, widely distributed, and invariably gregarious, the species which satisfies all conditions is ready at hand in Pseudosphinx tetrio, as the standard type or nearest modern representative of the ancestral Sphingid form ; for it, too, in the adult larval stage is only a great big baby, and from its well-known abundance and wide distribution it affords a better starting-point or basis for the argument than swainsoni. Once again, if the ancestral Sphinx formed a brightly-coloured and striped pupa beneath a web on the surface, as does Isognathus to-day, or a highly lustrous brown pupa with black design like P. tetrio, affording scope for development, it seems quite to accord with my theory that some of the offshoots should have adopted the subterranean method for the safety of their pupae, thus becoming modified to a plain brown without design, and that others, like Xyloplianes, while still spinning a fragmentary web on the surface, should have found it expedient to sink into obscurity by producing pupae which resemble wood, dead leaves, or pieces of bone. I may be suggesting the impossible, but on the chance that some enthusiastic entomologist, who is also an evolutionist expert, may be sufficiently interested to look into the matter and elaborate its details, I have propounded my romance, and I can only trust that it may not be considered far-fetched. 287. Pseudosphinx tetrio. (Plates T.Z.S.) R. & J. p. 353. One of the commonest moths in Para as in other parts of the continent, its immense black, yellow-ringed, and red-headed larva frequently showing up Novitates Zoolooicae XXVII. 1920. 375 in gardens and public squares on the Frangipanni tree. A large batch often completely strips the tree of its leaves, and this gregarious habit, already alluded to in connection with P. albiplaga, as exceptional in Sphingidae, can, I think, only be explained on the supposition that the possessor of bright warning colours enjoys some immunity from predatory attack. These great larvae may often be seen sunning themselves on the trunk and twitching their heads about in a seemingly nervous fashion. A few strands of silk are spun beneath fallen leaves to form the puparium, and the highly glossed pupa is marked with black lines, especially on the wing-cases, as in Isogjiathus. The female moth is considerably larger than the male and of a lighter grey, and both sexes, which come freely to light, show no special local variation. I have never found the species attacked by parasites. Length of j>roboscis in female moth nearly 2 in., in male 1£ in. Genus ISOGNATHUS. As I have occasion only too frequently to deplore my inability, after prolonged residence in the country, to record anything about the early stages of certain species both rare and common, may I be allowed a small boast in respect to Isognathus, where I have had an almost continuous run of good luck ? This genus, as it seems to me, is one of the most interesting, and yet, so far as my acquaintance with its species goes, is one where the greatest confusion prevails and entire revision is necessary. I will therefore record my experiences in rough chrono- logical order for what they are worth, and point to the conclusions to which they seem to lead. I began with P. tetrio and /. sicainsoni (see T.Z.S. p. 92), finding both species in 1918 in the Interior of Peru feeding on " caucho de monte," a tree which I wrongly described as a wild Ficus, but is in reality a species of Plmniera (not Plumeria, as in R. & J.), Apocynaceae. In my first month after reaching Para, July 1911, I took the single, white- banded larva, which produced a crippled moth like swainsoni and which, until more material is available for comparison, can, I think, only be regarded as the local caterpillar form of this species, as rare here as it was common there. Returning to Para in 1912, I restarted my investigation of the Plumierae, sucuuba, fallax, phagedaenica, etc., and, though I never chanced on the same caterpillar again, I very frequently took young and matured examples of leachi, the larva of which up to the fourth instar is very similar, but totally unlike in the last stage. The next to turn up was a single full-grown larva of excelsior on one of the same plants, different in important respects from leachi, as the figures show, but obviously an adjacent species with a longer tail and designed on the same model. From that day to this I have taken the larvae of menechus in all stages, twice on Artocarpus integrifolia (Moraceae), but in every other case on Plumiera. Journeying to Manaos, the examination of the local Plumierae at once yielded three species, a full-grown leachi, eight tiny caricae which I successfully reared to the moth on my return to Para, and a new species referred to below. In 1917 I again took leachi and caricae at Porto Velho, and caricae once again at Per- nambuco in 1918, all being found exclusively on Plumiera. Before this, however, I had accidentally come across a single larva of an Isognathus on Allamanda 376 NOVITATES ZOOLOGICAE XXVII. 1920. cathartica which turned out to be scyron ; this led to the finding of so many others, that I was soon aware that it was undoubtedly the commonest species of the genus in Para. Reverting to my entirely new species, two young larvae in the second instar were found feeding on a narrow-leaved species of Plumiera at Taruma near Manaos in January 1913. One died in moulting, the other fed up during my return to Para, pupated, and duly emerged on March 20. I subsequently found more young larvae and some eggs in February and March 1917, not only on the shores of the Taruma lagoon but on the banks of the Rio Negro nearer to Manaos, and in November of that year I rediscovered the species at Nazareth on the Rio Faro, in the State of Para. I have now bred it on some eight occasions, and it has been designated mossi in my honour by Mr. B. Preston Clark, of Boston, Mass. On two different occasions odd larvae of caricae were discovered among the rough vegetation lining the beach at Chapeo Virado, Mosqueiro, twenty miles north down the river ; and now, as recently as the middle of March 1919, I find the species to be very abundant there, a few being taken on Plumiera, but the majority, upwards of a hundred in all stages of growth, occurring on small bushes of Allamanda growing wild in the sand close to the water's edge. Though other Isognathi will grudgingly partake of the alternative pabulum in captivity, this appears to be the only species to be found in nature on both Plumiera and Allamanda. On the other hand, while thriving equally well on either, it appears to be strangely fastidious in regard to locality and to the precise position and growth of the plant chosen. Out of my 90 Para species caricae is the only one that has not yet been noted in either larval or imaginal condition close to the city. This is strange, for the species is obviously prolific, and its two food-plants are abundant here. By a comparison with P. tetrio and the various species of Isognathus in regard to early stages, as well as in the moth, caricae is perhaps the most difficult to place accurately. Seeing that its larval form and habits resemble those of tetrio, and that its pattern as a moth, as stated in the Revision, is more ancestral than that of the other species of Isognathus, it would seem to be more correct to place it next to tetrio — that is, at the beginning rather than at the end of its genus. It should, however, in this position, be regarded as an offshoot, for otherwise it interrupts what would appear to be an equally natural sequence from tetrio to swainsoni, etc. My last species is one which I have recently taken in abundance at Per- nambuco, and which my friend T. T. Dyer has still more recently had the good fortune to capture here in Para as a male at light on February 24, 1919, thus adding a species to our already extensive list of local Sphingidae which must be as rare in Para as it is common in Pernambuco. My first acquaintance with it was as a moth at light in this latter place in May 1918, and I took it at the time as a worn but exceptionally grey specimen of scyron. Finding out my mistake, and returning thither in September, I explored all available plants of Plumiera and Allamanda, and was almost at once rewarded by the discovery of many larvae in all stages, found feeding in gardens on Allamanda cathartica, but never once on Plumiera. These larvae were so similar to scyron and so different to those described by Schaus and Gundlach (R. & J. p. 358), as found on Plumiera and producing rimosa, that I was again led to associate my Pernambuco species with scyron and regard it as an extreme local race of this species. This I am now convinced cannot be NOVITATES ZOOLOGICAE XXVII. 1920. 377 the case, if it be only by the finding of a single moth, Mr. Dyer's perfect grey male, alongside the typical brown and only known form of scyron. Again, though the moth tallies with the description given under the head of rimosa papayae in R. & J. p. 359, I am strongly of opinion that the first name is erroneous and the second simply misleading, the unhappy hit, as it seems, of Boisduval in 1875 ; for in regard to the latter, the subspecific term papayae only puts one off the scent, as in my experience and that of others not one species of the entire genus ever touches Carica papaya as a food-plant. The same remark applies with equal force to Linne's name caricae, a mistake stereotyped since 1764. Possibly it was the discovery of the larvae of the common Erinnyis ello and alope, as more or less close relatives feeding on Cacrica papaya, which has led to this unwarranted assumption. It may here be noted that the entire group is all but exclusively associated with Apocynaceae, and that Plumiera belongs to that Order and not to Euphor- biaceae. In appearance and habits as an Allamanda-ieeder, the new species is obviously more closely allied to scyron than to any other, and must be granted an independent name. Since writing the above, Mr. Preston Clark has received my consignment of a dozen perfect bred specimens from Pernambuco. He is convinced that this is a new and distinct species ranking between rimosa and scyron, which he proposes to call allamandae. Finally, I gather that congratulans has already dropped out of the category of true species, and is now regarded simply as an extremely dark subspecies of rimosa from Cuba. Piecing then together all the scraps of information which have accrued concerning this group, more especially in so far as they relate to early stages and food-plants, may I take the liberty of suggesting the following order as a nearer approximation to the true sequence ? — 1. tetrio. 2. caricae. 3. swain- soni. 4. leachi. 5. excelsior. 6. menechus. 7. mossi. 8. rimosa. 9. allamandae. 10. scyron. While retaining the old numbers for reference, I feel bound to adopt this order in my present notes so as to avoid further confusion and not interrupt certain natural sequences. 295. Isognathus caricae. (Plate 3.) R. & J. p. 360. Not found as a moth, and taken only at the distance of 20 miles from Para. The young larva on emergence from the egg is almost black, but after moulting bears six lateral patches of white, a dull red head, a yellow patch at base of tail, and a row of dorsal bristles. In the succeeding instars considerable development takes place, with an ever-increasing number of intricate markings in blue and red and finely pencilled lines in white and yellow, as shown in the figures. It is to be noted that the customary white belts in this case are hardly more than a couple of fine white rings near the interstices of each segment, first on a dull black ground, becoming intensely black and velvety in the final instar. In the redness of its head, the comparative shortness and thickness of its tail (which, however, generally bears a white ring about the middle), and in the coloured patch at its base, caricae undoubtedly approximates to tetrio. In the strong yellow ring on segment 2, the yellow lateral skin-folds and sundry other marks, it shows a departure from all the rest. 378 Novitates Zoologicae XXVXI. 1920. Among those taken in the last instar at Chapeo Virado many were brilliantly adorned on the back of each segment with square patches of carmine-red, giving them an exceptionally rich and handsome appearance. In the matter of size and agility, they reminded one much of tetrio, readily falling to the ground when approached, exuding large drops of a yellow fluid from invisible apertures in any part of the skin, and without any apparent damage (noted as a characteristic of the entire group, but to a less degree), and making off with great alacrity over the grass and hot sand from those defoliated stems and gnawed stalks of Allamanda where they had been feeding and basking in a blazing sun. A large and free cocoon of strong red-brown silk is spun among grass and debris on the surface of the earth, and the pupa, which is formed in three days, is of a distinctly lighter straw- yellow than that of any other species of the genus. As though to emphasize its difference from all the rest, even in later life, the dark band bordering the hindwing of the moth, so characteristic a feature throughout Isognathus, is in caricae merely represented by some seven or eight dark radial streaks on a light yellow ground. Length of proboscis in both sexes 1 § in. 289. Isognathus swainsoni subsp. ? (Plates 3 & 4, and compare T.Z.S. swainsoni, Plate 8.) R. & J. p. 355. This may be a new and hitherto undescribed species, one nearly full-fed larva which pupated but produced a cripple in August 191 1, and one wasted moth in the following year, being all that I have yet to record. This moth, with a very broad dark border on the yellow hindwing, resembles sivainsoni, which species I bred in Peru from larvae with no trace of red on their heads, and had rather shorter tails ; moreover, the white predominated over the black. My Para larva was essentially black with white belts, and as red as P. tetrio on head, plate, anus, and claspers to the end of its caterpillar existence. With such scant material, however, I am inclined for the present to regard both moth and caterpillar as simply the eastern geographical race or a local form of sivainsoni, a specimen of which is recorded as having been taken at electric light in Para by Dr. Goeldi and sent to the Bern Museum. It is evidently very rare here, as all attempts, oft-repeated throughout the district, to retrace this remarkable and highly conspicuous larva on the " sucuubas " of the matto, or the Frangipanni of gardens, on which latter it fed in captivity, have so far failed. Pupa formed in a surface cocoon, and in itself indeterminable from leachi and the rest (except caricae), the various species showing little if any essential difference inter se beyond the matter of size. When living they are all of a bright and lustrous cadmium-yellow, with numerous tar-black streaks marking the wing- sections, clearly defined and somewhat variable big spots on head and thorax, and finer transverse lines and spots on the abdominal segments. They become uniformly dark before emergence. 288. Isognathus leachi. (Plates 3 & 4.) R. & J. p. 355. Quite a common species at light in Para. Like others of the genus, frequently taken as a larva on various wild species of Plumiera, and will readily take to Frangipanni in captivity, NOVITATES ZoOLOGICAjf XXVII. 1920. 379 The young black-and-white-belted larva with ochreous extremities in the first three instars appears to be identical with sivainsoni. A great change, however, takes place in the fourth instar, the ground-colour lightening to mauve and the white belts becoming creamy, rounded off before reaching the legs and claspers, and being finely outlined in black. A still more remarkable change in the final instar produces an entirely distinct-looking larva, the head being salmon-pink shaded on the face by umber-brown, the back adorned with a series of irregular X-like marks and the sides with light-coloured ovals. A couple of light longitudinal stripes divide the dorsal from the lateral areas. The entire ground-colour is now of a delicate violet, legs black, claspers ochre in black settings, and all the light patches are finely outlined with black. No parasitic attack observed. Length of proboscis in male moth If in. 294. Isognathus excelsior. (Plate 4.) R. & J. p. 359. Moth common at light in Para in 1912 and a few every year since, but never so abundantly. The larva, only once taken at full growth on sucuuba, was similar to leachi, but differed in the following respects : tail bluish at base, stouter, rougher, and nearly twice as long, quite the longest of the genus, in fact ; ground- colour dark steel-grey ; dorsal and lateral patches, together with interrupted stripes, claspers, and upper half of legs of a warm ochreous colour, the dorsal patches more V-like, being cut off posteriorly by the transverse black belts which complete each segment ; anus light but adorned by nine dark marks, a couple on the flap representing the hard tubercles or spurs which are shared by all these species alike. On the analogy afforded by swainsoni and leachi, it is highly probable that in the early instars excelsior partakes of the same black- and-white- belted design which characterizes those species. As the moths have nearly always appeared in fresh and perfect condition, I fail to understand the extraordinary rarity of this larva by comparison with leachi and menechus, unless, like the latter, it possesses some alternative and possibly preferred natural food-plant. Length of proboscis in male moth 1 £ in. 291. Isognathus menechus. (Plate 4.) R. & J. p. 356. Frequently bred from larvae found on the " sucuubas " of Para, and on several occasions also I have taken it feeding on the leaves of the Jaca tree, Artocarpus integrijolia (Moraceae), but, as a moth, only once or twice has it occurred at light. This difference in the degree of susceptibility to the attrac- tiveness of light with species known to be common, and which are yet but seldom thus ensnared, is very extraordinary. Not less strange is the observation frequently made that certain arc lamps, apparently equally attractive and well-placed, should be variously selected by different kinds of moths, one, for example, being the rendezvous of a host of common Sphingids, another being the particular lamp where the greatest variety of ISynlomidae have occurred, and so on with other groups, while the rarer or more exceptional Sphingidae, 380 NOVTTATES ZOOLOOICAE XXVII. 1920. such as Oryba kadeni and achemenid.es and the species under consideration (though here it is not rare), will, like the usher of the poet, be found " remote from all," the same species of moth, for example, occurring time and again in the same position and on some particularly favoured white wall that catches the light of a street-lamp. Though not without its exceptions, of course, this small phenomenon has been so frequently noted by my friends as well as by myself that I make a passing mention of it, for it seems to suggest that artificial light may, in accordance with its degree of intensity, quality, or peculiar waves of vibration, extend a varying attractive influence upon different species and even upon different families and groups of insects. It may be for some such subtle reason that here and there we meet with an exception even among the Sphingidae, as a family so notably drawn to light, but with instances occurring, like menechus, where the impelling rays find but little response in its optic retina. The larva of menechus, with but slight modifications, once again corresponds closely with leachi, for example, in that its first three instars are characterized by the black-and-white-belted design with ochreous extremities, while the fourth and fifth instars differ immensely from this, from one another, and from others of the genus at these particular stages. To describe these changes in all their details is difficult and perhaps unnecessary, as the main differences can readily be gauged by a careful comparison of the figures. It is, however, interesting to note that the oval patches, which adorn the sides of leachi and excelsior in their final stages, are prepared for in menechus by a series of finely curved black lateral lines in the third instar, perfected in the fourth, and merely enlarged in the final stage. The dorsal area in this species develops marks of a more elongate and subdivided character, increasing depth of colour, and in general foreshadows the linear or longitudinal stripe-formation which reaches its climax in mossi (sp. nov. Clark). WhUe excelsior possesses the longest tail, menechus would seem to exceed all others of the genus, except perhaps caricae, in the bulk and weight of its full-fed larva, occasionally falling but little short of a small P. tetrio. A larva found on jaceira (the Jaca tree) once produced dipterous parasites. Length of proboscis in female moth If in. Isognathus mossi. (Plates 4 & 10.) Isognathus mossi Clark (1919). Two larvae in the second or third instar were taken on my second expedition to Manaos in January 1913, and were presumed to be those of rimosa, a species which at that time I had never seen. These were found feeding on a narrow- leaved and possibly undescribed species of Plumiera which grows plentifully on the white sandy shores of the Taruma lagoon and the Rio Negro near to Manaos. It would fill a chapter to narrate the details of my subsequent endeavours to obtain more of this unknown rarity : how various kind and interested friends in Manaos in 1917 arranged special expeditions to Taruma for me by their private motor-launches ; how, before leaving for Iquitos, I secured a stung egg and then two diminutive larvae, only to have them ruthlessly destroyed as soon as I NOVTTATES ZOOLOGICAE XXVII. 1920. 381 got on board by a miserable horde of ants ; how on my return I got three more hardly bigger, and next day found the corpse of one sucked dry by a bloodthirsty spider, etc., etc. But suffice it to say that in the end I managed after prolonged and diligent search — and my thanks will ever be due to Messrs. Sutton and Fair- weather and Captain Roxo — to procure some 5 or 6 more in their second, third, and fourth instars. Leaving Manaos on March 22, I at last succeeded in pro- tecting them from foes and feeding them up to good-sized larvae on the boat returning to Para, and finally I had the extraordinary good fortune to rediscover the species at Nazareth on the Rio Faro on the same voyage. As the Cuyabd had to stop here for some hours to take in timber, I availed myself of the opportunity of going ashore and searching for fresh fodder. This place is situated on the boundary line between the States of Para and Amazonas, and from the former locality is nearer to Belem by some 350 miles. The outlook was propitious, for the white sandy beaches lining water as black as the Rio Negro were well clothed with a varied scrub vegetation. Exceeding my utmost anticipations, I was again successful, for not only did the same particular variety of Plumiera grow there plentifully, but my new Isognathus was actually there as well, showing a remarkable constancy to a special type of plant and locality. In great jubilation I returned to my boat with not only enough fresh sucuuba to last for the rest of the voyage, but with an additional larva found at full growth on the stem of a plant and a couple of eggs, which latter, however, were stung and useless, as I could see at a glance. I now had 8 larvae, and all but 1 fed up well, pirated, and in Para three weeks later 7 perfect males and females of this very distinct new species emerged. The pupa is of the normal Isognathus colour, pattern, and form. The moth may be described as intermediate in size between menechus and rimosa, rounder and broader in wing and of a more sooty grey than any of the others, while the strong black band on the yellow hindwing is fully as broad as in menechus or excelsior. The newly hatched larva, which very readily falls from its leaf, is dead black with a few touches of white in its posterior half and a black tail of almost its length curved forward. After moulting, it possesses a distinctly chequered design in black and white. In the third instar this is maintained, the longitudinal white lines on a black ground being interrupted by the transverse black rings of the interstices. The extremities are ochreous, as in menechus, and its black tail with a white ring corresponds with that species in its form and length. The chief differences noted in the last two instars were the amalgamation of the spiracular patches into one continuous broad lemon-white band, the increased yellowness of head and plate, the anus conversely growing duller, while the ground-colour becomes a warm chocolate-brown with longitudinal stripes of Indian red and lemon-white adorning the back and sides. Isognathus allamandae. (Plate 10.) Isognathus allamandae Clark (1920). Having already dealt at some length with this species, I need not repeat what has already been said on p. 376. Let me, however, emphasize a few points which distinguish the larva. The pattern throughout, like that of scyron and 25 382 NOVITATES ZOOLOGICAE XXVII. 1920. the later stages of mossi, is one of numerous longitudinal stripes and lines in grey and white, the spiracular band being more or less definitely pink. Compared with scyron, which it most closely resembles, it is more clearly lined but paler and greyer, scyron developing from pale grey into a dirty brown with a subdued brown chequered design not found in this species. Small black and yellow marks adorn the front of the plate. The dark grey tail is exactly like that of scyron — that is, both are equally short in proportion to the full-grown caterpillar when contrasted with a species like leachi, for example, and both are twice ringed with white. It is a dull and dowdy creature, and in the final instar, like scyron, it always hides away in the shade during the heat of the day on the dry stems of its food- plant or on some adjacent object as dull as itself. On Allamanda cathariica in gardens and on a closely related wild species alone did I ever find it, and, if present at all, it generally occurred in fair numbers, the same moth having obviously deposited a number of eggs separately on different parts of the plant. The favoured situation was where the Allamanda was growing as a verandah creeper, and here from the varied size of many larvae it was no less obvious that one beheld the progeny of more than one mother. Rather loosely-spun cocoons were found among the dried portions of ferns growing next the wall beneath, many containing empty shells, but some newly formed, and not a few containing old pupae riddled with holes by the exodus of parasites. The pupa itself, though more slender in proportion to the size of the moth, is in colour and pattern constructed on exactly the same lines as scyron and the others. Though all the above observations were made in Pernambuco, Mr. Dyer's single male, taken at light in Para on February 24, 1919, provides sufficient justification for the inclusion of this species as one of the Para Sphingidae, no matter how rare it may be, and apparently is, locally. I note that Schaus says, in reference to rimosa inclitus, that the larva changes to pupa in from 10 to 14 days. This is surely a mistake, 3 or 4 days at" most with all my species, and so far as I can remember with all other Sphingidae,, being the limit of time during which the larva lies in its puparium' before the final moult, and most of them emerge in little more than 3 weeks later. 290. Isognathus scyron. (Plates 2 & 4.) R. & J. p. 356. This is undoubtedly the commonest and, except for the one just dealt with, the smallest species of Isognathus in Para, the moth frequenting lamps and the larva nearly always to be obtained in the public and private gardens of the city by searching the leaves and stems of the lovely Apocynaceous shrub or creeper Allamanda cathariica. With this, like the former, it appears to be exclusively associated, never in nature having been taken on Plumiera. The ova and young larvae when grey are easily found on the under-surface of leaves, but in the last instar, being of an earthy-brown colour, they successfully hide away during the day on the dusty-brown stalks or in curled-up dead leaves. Having studied its development from the egg, several of which are often laid upon the same plant, the following notes may be of interest. 1st instar. — Sooty black, the young larva when examined under the lens exhibiting strong characteristic features.

Segment 2 with a couple of prominent black dorsal tubercles surmounted by fine hairs and backed by a transverse white belt which connects two subspiracular white bands. These bands, which are very white in the anterior half, become hardly visible from segment 7 to 11 inclusive, and appear to be sooted over. The upper parts of segment 12 and the anus are clear white sprinkled with black dots. Below on the black anal flap are situated the couple of strongly developed black spurs, which are reduced in altitude inversely with the growth of the caterpillar, but always present. Many fine bristles adorn the back, and the curved dark grey tail, which at this period is fully three-quarters of its entire length, is rough and distinctly bi-lobed at the extremity. In instar 2 the dorsal and lateral areas become grey with black dots. In instar 3 a lighter grey is assumed, bearing a distinct medio-dorsal black line. The light lateral band is now uniformly white, contains the spiracles, and is bordered above with black. The plate behind the head is now yellow and adorned with two small black tubercles and two other black spots. The tail now and in the two succeeding instars is ringed near the base and near the tip with white. In instar 4 the design of the adult larva prevails, the colour in individual specimens varying between a light vinous and an umber-brown freckled with darker touches, the head and plate a dull yellow, the back sombrely lined, and the sides relieved by the spiracular bands, which are now of a very dirty or clouded pink and contain light spiracles. The pupa, which is commonly found spun under moss on tree-trunks, is rather stouter than the former species but otherwise identical : and it is occasionally found riddled by the holes of parasites.

As with Isognathus, so also in Erinnyis, is there a standard generic pattern of pupa to which the species wonderfully approximate and which ought not to be confounded with the former. While allowing for their variability in size, the type is undoubtedly like Isognathus in general form and colour, and is similarly adorned with black stripes on the wing-cases and with short transverse black dashes on the ab- dominal segments, but it differs in certain important respects : ( 1 ) The yellow colour generally inclines to a mahogany red and both extremities tend to be suffused with black. It must here be remembered that the bright colours, whatever they originally were, are seldom as bright after the emergence of the moth, and the precise tone or tint cannot be gauged from the empty pupa-shells of a collection. (2) The black design on head and thorax, if apparent at all, is much less pronounced and perfect. (3) It is longer for its size, or, in other words, somewhat narrower in proportion to its length. (4) The cremaster, though sharp-pointed, is invariably stouter at its base. (5) Its surface, though glossy, is rather less highly glazed. By a general grasp of these features it will be seen that several of the descriptions given in the Revision of the pupae of Isognathus and Erinnyis are very deficient, and some actually erroneous, 384 Novitates Zoologicae XXVII. 1920. A loose-spun but ample cocoon, similar in all respects to Isognathus, is formed by all these species under dead leaves or concealed among herbage on the surface. 296. Erinnyis alope. (Plate T.Z.S.) R. & J. p. 362. Commonly observed as a moth at light in Para or as a larva feeding on Hevea, Carica, Curcas (Jatropha), Manihot, and other Euphorbiaceous plants. If green in the early instars, it is generally of a dark brown richly mottled in the final stage of the caterpillar with a yellowish ventral area, and is readily dis- tinguished from ello by its more prominent tusk-like blunt horn, which is smooth and light-coloured. Its well-known thoracic patch of colour is shared in common, though in varying tones of red and black, by ello, oenotrus, and crameri, but not by lassauxi and obscura. Puna very similar to ello but rather longer. Length of proboscis in male moth 1J in. 297. Erinnyis lassauxi, forms lassauxi and omphaleae. (Plate 10.) E. & J. p. 363. Moth not uncommon at light in Para, and now frequently bred from ova and larvae found on a garden creeper with sweet-scented white flowers, known locally as " angelica doar " (Asclepiadaceae), but never on Morrenia, as recorded by Burmeister, who also gives the same food-plant for oenotrus. I doubt if he was correct in either case, and he most certainly could never have seen the larva of lassauxi when he said that it was very much like that of ello, for nothing more different in adjacent species could well be imagined ! One might be excused for anticipating that such would probably be the case, but the fact is far different. So utterly unlike was my first-found larva, that I was unable even to guess its genus, or do more than rank it in Sesiinae. Only when it formed a pupa out- wardly identical with alope did I judge that it must be lassauxi, for I had already taken the larvae of all the other local species of Erinnyis except domingonis, and this was twice the size. Not having my figures by me now, I can only describe it very generally by referring to its truly remarkable mimicry of the food-plant, the white-knobbed swollen process on the thoracic segments exactly simulating the end of a flowering stalk from which the flowers had fallen, these white lobes representing drops of the congealed milk or latex which is so char- acteristic of this plant and other Asclepiae, and the four side-patches of light brown in strange design on a sage-green ground, inclining to milky-white dorsally, admirably repeating the twining green stems with their ever-present light and brown scars. Not a mark but counted for something in the general scheme of resemblance to surroundings ; and if this does not happen to be its natural or original food-plant, it can doubtless be sustained by a very similar wild species with large leathery leaves growing in the matto. After the first accidental find I have frequently taken it in gardens, but only on this plant, the larvae, except when very young or when eating, generally reposing in a strangely contorted attitude among the stalks. As regards the moth, and in response to the suggestion made on p. 364 of the Revision, I may state that the two forms /. lassauxi and /. omphaleae with NoVITATES ZoOLOGICAE XXVII. 1920. 385 the cinnamon-rufous patch of varying size on hindwing are both 'very distinctly present here, two fine specimens of the latter being entirely without the black spots on under-surface of abdomen. As I used to take both forms of this moth in Chanchamayo, Peru, it is obvious that they do not represent geographical races or subspecies. Length of proboscis in both sexes If in. 298. Erinnyis ello. (Plate T.Z.8.) R. & J. p. 365. Enough has already been said in the general introduction and elsewhere of this extremely common species, and the only additional touch of interest that I might here record is that I once found the larva in its fourth instar in Barbados feeding on the leaves of the deadly " manchineel " (Euphorbiaceae), and that its horn in this case, hitherto unnoticed, was like a knob, swollen but tipped at its extremity, and capable of a small degree of inflation and contraction. Length of proboscis in both sexes 1J in. 300. Erinnyis oenotrus. (Plate 10.) R. & J. p. 367. Of very frequent occurrence as a moth at light in Para, less often observed as a larva, and taken only for the first time in July 1917 on a small bush of Zschokkea sp. ? (Apoc), growing in the Para Bosque. In November of the same year I took 5 more at Porto Velho on the same plant and on a species of Echites with dark green and rather hairy leaves, as rare here as it was abundant there. On this same Apocynaceous plant I also took several larvae of Pachylia resumens, to be referred to again. In early days the larva is of a uniform light green, the dorsal and lateral areas divided by the customary pair of light stripes leading to a long, curved tail. In the later instars it has both green and grey-brown' forms, the latter much freckled throughout with tiny brown touches and a double series of brown spots. Though distinct enough from the others to the eye, it is difficult to describe beyond saying that it is like ello, but proportionately longer and more slender, and often rests on the brown stalks with three pairs of claspers retracted, giving it a very geometer-like appearance. Its horn, from being like a knob with a tip in the fourth instar, is reduced in the last stage to the merest sharp point, exactly on a par with ello. The colour of the pupa is rather brighter than that species, and is less obscured by black at the extremities. Length of proboscis in female moth 1 J in., in male If in. 301. Erinnyis crameri. (Plate 7.) R. & J. p. 368. As common a species as a moth at light in Para as the former, but in the larval form only seldom seen. The first was discovered accidentally in August 1914 as a pale green larva feeding on a species of Tabernaemontana {Apocynaceae), and this led to more finds on the same plant and to one on a kindred species. Its tail up to the last instar and its transverse light belt on the thoracic segments recall ello ; there are ;also the customary pair of light stripes dividing the dorsal from the lateral area. 386 NoVITATUS ZoOLOGICAE XXVII. 1920. In the final stage the larva generally assumes a uniform ochreous-brown coloration, inclining to blue and freckled with light spots and black dots. The claspers are ringed with velvety blue-black, the face and legs lined with black, and the interstices of the thoracic segments adorned with two belts of bright vermilion. The second of these is centred with black, but neither of the belts is in the least degree visible when the larva is at rest, reposing like the last species geometer-wise with retracted claspers and stretched across the fork of a bough, a perfect stick among sticks and most easily overlooked. Pupa very similar to ello. 302. Erinnyis obscura obscura. (Plate 7.) R. & J. p. 368. A fairly common species at light in Para, and once again but seldom seen in the larval condition. This, however, was first found in May 1913, and has occasionally been taken since by searching a somewhat inconspicuous small- leaved creeper, Gonolobus sp. ? (Asclep.). These occur in both the green and grey-brown varieties which characterize ello, and, though a smaller species, and without the dorsal patch of colour on the thoracic segments, it bears a general resemblance to that species. Like all the others of this genus, its anterior claspers are retractile, and it protects itself by adopting the same geometer-like attitude when at rest. The pupa, though a little lighter in tone and only half the size, is practically identical with lassauxi, i.e. with rather more black than oenotrus and less than ello and alope. 303. Erinnyis domingonis. R. & J. p. 370. Much rarer than the preceding species in Para, taken freely at light in 191:: but only very occasionally since, and the larva remaining undiscovered. From its obvious close relationship to obscura, it is natural to assume that the larva is constructed on much the same lines as that species, and that it will eventually be found to be also associated with Gonolobus or some kindred plant in the Order Asclepiadaceae. 305. Grammodia caicus. (Plate 7.) R. & J. p. 371. An interesting species not hitherto recorded for Para, the moth occasionally coming to fight, and the larva, after the first accidental find jat Val de Caes, four miles down the river, being frequently taken in small numbers on two species of Echites and once on Zschokkea (Apocynaceae). The larva is a somewhat plain creature, varying in colour between pink, light brown, and pale olive-green, and possessing a straight, erect horn up to the last instar, when there is hardly more than a hump. With the dorsal area enclosed by two stripes from face to tale, it at once suggests Erinnyis, but there are some evenly distributed light spots, and in form it is really more that of an elongate Koctuid. The cocoon is in all respects like that of the previous genus, a moderately stout-spun web amongst vegetation on the surface. The pupa, too, is extremely NoVITATES ZOOLOGICAE XXVII. 1920. 387 similar to that of Erinnyis, but the light yellow ground-colour is more banded and spotted with black and it is distinctly less glossy. 306. Pachylia ficus. (Plate T.Z.S.) R. & J. p. 373. Again we come to a species so widely common and of which so much has already been said in the general introduction and elsewhere that there is little more to add. Though not so often drawn to light as might be expected, its great fat green larva is nearly always to be found on the neatly cropped Ficus benjamina trees which adorn the avenidas and pracas of the city. It occurs here also on several other species of Ficus with foliage of very diverse character, and it is sometimes obtained from the leaves of the common fig-tree in gardens, but here, at any rate, I have never found it on Artocarpus or Cecropia, the forms of plant-life so greatly preferred by its congener syces. The strange lichenous variety of ficus also sometimes occurs, and the caterpillar, when it has assumed the vivid orange coloration prior to pupation, is constantly being picked up in the road by non-entomological friends, who are quite disappointed to learn that they have not in this case been privileged to add a rarity to the collection. 307. Pachylia syces syces. (Plate T.Z.S.) R. & J. p. 374. Not uncommon but rarely taken as a moth at light in Para. When met with in the larval condition, it has always been found associated with Moraceae, Artocarpus integrifolia, Ficus sp. ?, and Cecropia, and too often is it already doomed to destruction by dipterous as well as hymenopterous parasites. I have now frequently bred the moth, and found it a very common species in Pernambuco on the Jaca tree which so largely prevails there. The larva, after assuming its characteristic series of black belts, comes down to earth and is then frequently seen by the natives. On those occasions when the crevices of the roots of its own tree offer sufficient inducement to it to stay, its large, glossy brown, and vivacious pupa may readily be found in a loose-spun cocoon under stones and dead leaves. 308. Pachylia darceta. R. & J. p. 376. Though the female is rarer than the male, the moth in both sexes is of frequent occurrence at the electric lights of Para, and I once took a male similarly in the streets of Manaos. This large species, however, is one which up to date has baffled all my attempts to elucidate the mysteries attaching to its early stages ; and after having had my faith shaken by what has recently come to light in regard to the larva and food-plants of resumens, I incline to the view that darceta, too, is a somewhat distant cousin, is not to be found associated with Moraceae, and may possibly feed on a species of Davilla (Dilleniaceae). This, at any rate, is the favoured pabulum of such allied genera as Aleuron and Enyo, and frass, too big for their species but appropriate for darceta, has been noted beneath such a plant, sug- gesting the idea. Some of these creepers growing in dense thickets are naturally 388 NOVITATES ZOOLOGICAE XXVII. 1920 very difficult to explore fully. On the other hand, darceta may be associated with some completely different type of growth and live well above one's head. That some very large species are thus accustomed to inhabit the upper branches of enormously high trees, utterly beyond the reach of the most skilled climber, is too apparent by the frequency with which one discovers the excrement in some void place on the ground beneath, sometimes of great size and possessing peculiarities of form new to the eye. Length of proboscis in male moth If in. 309. Pachylia resumens. (Plate 10.) R. & J. p. 376. Moth in both sexes of very frequent occurrence at light in Para as elsewhere, but the larva rarely seen. Indeed, being misled by the statement that it was known, and that it resembled a small edition of ficus (vide Revision, p. 37S), on whose authority I know not, I wasted much time during my first five years in Para in exploring Ficus trees of all descriptions ; but the " smaller " larvae resembling ficus always grew big, and were, in fact, that species in every instance. Once again, therefore, one has to deplore the lack of careful and thorough observation on the part of some moth-collectors in foreign parts, who too readily assume that they have seen the larva of the moth they have caught without having taken the trouble to rear a single specimen. In point of fact, the larva of resumens, beyond being green, is not in the least like ficus, and could never be confounded with that species by any one who had really seen it. The yellow side-stripes are not only more numerous, but they form a series of V's at the mesial line and lead up to the horn. In ficus and syces they run contrariwise, and terminate abruptly with the light longitudinal lines which enclose the dorsal area. In resumens this area, though lighter, is not clearly divided off by lines at all. The long, turned-down tail of early days is replaced in the last instar by a tiny point surmounting a prominent hump. Again, the texture of the skin. the swollen nature of the thoracic segments, and the black-and-yellow ringed base of the legs on segments 3 and 4, give resumens far more the appearance of being a closer ally to Perigonia or Sesia than to its neighbours in Pachylia. The cylindrical glossy dark brown pupa with its long, sharp-pointed cremaster seems also more to reproduce the form of Epistor than that of Pachylia. Finally, in its food-supply it appears to be limited to certain species of Echites in Apo- cynaceae, sharing one with Leucorhampha, but ignoring at least three other varieties. It was in Porto Velho that I first took the larva in November 1917 feeding on a species with dark green and rather hairy leaves, and which appears very rarely here. In Para, however, I have twice subsequently taken it by the railway line feeding on a distinct species of Echites with large, yellowish, and rather glossy leaves. Length of proboscis in male moth 1 in. We come now to the only two known species of Oryba, and if a proud mother is justified in exhibiting her bonny twins to an admiring world, it is with a kindred satisfaction that I present my two golden babes, partly because they are both so handsome and interesting in all their stages, and partly because, after keeping NOVITATES ZOOLOGICAE XXVII. 1920. 389 me waiting for a long time, they both ultimately rewarded my patience by coming to light in more than the technical sense. 310. Oryba kadeni. (Plate 5.) R. & J. p. 379. By no means uncommon in Para, this exceptionally handsome moth with its rich combination of green, yellow, and black is much drawn to light, both sexes often being found in the neighbourhood of electric lamps by day, though not so often captured. This species and its congener seem to be endowed with an extra degree of nervous vitality, and make off in a wild flight, especially when approached in bright sunshine. I first figured the larva from two specimens found in the Interior of Peru, feeding on some very long-leaved plant of the Order Rubiaceae. Both pupated, but subsequently died owing to the rigours of a four days' journey to Lima. I correctly diagnosed the species at the time through the enormous eye-cases of the pupa, kadeni possessing, I believe, the largest eyes of all lepidoptera known ; but with the lack of absolute certainty I decided, on the expert advice of my friend Dr. Jordan, at Tring, to defer the publication of the figure. The matter is now settled beyond doubt by the recurrence of the larva on very many occasions in Para in all stages of growth on a long-leaved species of Palicourea with bunches of red and white flower {Rubiaceae). Though normally as yellow as a sunflower, with large black spots and stripes and, when full-grown, as big as Acherontia atropos, making it a very conspicuous object, I have twice found a brown-and-white-banded variety of the adult larva, so different in design as to suggest another species. Indeed, I thought that I had then obtained achemenides until its identity was revealed on emergence. The young larva is pale green with a whip-like bifid tail, and, with modifications of this appendage, a pale yellow or pink-brown colour is assumed, both tone and design gradually intensifying and forecasting the adult stage. How this most striking caterpillar can have been passed unheeded by collectors of moths and butterflies in the American tropics for so long is a puzzle, and it seems to suggest that those who are engaged in stocking our museums might occasionally do better service and deepen every one's interest in the study, their own included, if they would oftener leave the net and search for larvae. In my own case it is only by so doing that I have taken many of my best Sphingidae, and out of four at least that are absolutely new to science, two have never, been taken on the wing and only bred from the larvae. There are few things in nature to equal, still less to excel, even in the very moths which they produce, the larvae of Sphingidae in their superlative elegance of form and curve, blend of colour, and perfection of imitative design. The trouble of course is that they do not offer the same facilities for preservation as do the moths. A blown caterpillar, especially when large and green, as so many of the Sphingidae are, becomes too often a parody of its former self. Better success is met with at times in species that are ornate and deeply coloured, and when care has been taken not to over-blow them. But to interest a wider public, the accurate depiction of the living larvae on their food-plants in their characteristic attitudes at all stages is obviously the great ideal to be aimed at. How many strange and wondrous forms of life have been seen only to be at once forgotten, or occur simply as a 390 NoVITATES ZOOLOOICAE XXVII. 1920. fading reminiscence in the mind of the solitary observer who has been privileged to wander through the forest and swamp of the tropics ! Such deficiencies can and should be met by more descriptive notes, more hand-drawing, or more photography, with facilities for reproduction on a more extended and organized scale than has hitherto been attempted. The puparium of kadeni is a subterranean cavity, the walls of which are supported by a slight amount of silk. The pupa is of a bright mahogany-brown, stout but elegantly curved, with enormously large eye-cases and a very strong, broad, but sharply-pointed cremaster. Length of proboscis in female moth I in. 311. Oryba achemenides. (Plate 5.) R. & J. p. 379. This moth, though reckoned a rarity, is by no means uncommon at light in Para, but it is difficult, except by rearing, to obtain in perfect condition. It seems particularly fond of settling on overhead wires and in other exalted and impossible positions. It sits, like kadeni, with its wings spread at a wide angle, and flies off like a bird when approached. The resemblance between this species and the former is by no means so close in its early history as a general similarity in the moths would lead one to expect. Indeed, the parallelism between the two species hardly extends beyond the fact that they both have yellow cater- pillars with brown varieties, and that they are both Rubiaceous feeders. This species, however, as I at last discovered after long and fruitless searching on Palicourea, only feeds on Ourowparia, a strongly-built creeper which generally grows on the outskirts of swampy matto. The plant possesses glossy ovate leaves and big curved thorns like the claws of a vulture, and goes by the local and most appropriate designation of "Unha de gaviao." The tails of both Orybas when young are on the model of Isognathus, being whip-like and flexible, dark in colour, light-ringed, and distinctly bi-lobed at the tip. The evolutionary progress of the caudal appendage is, however, different, the tail being more sickle-like and prominently erected in the fourth instar of achemenides, suggesting the thorn of its food-plant, and becoming only a small hard button in the final stage ; while with kadeni, the long, slight, and curved-down tail of the fourth instar lapses into a tiny sharp point in the last stage. Both species possess very smooth velvety skins, but the difference is otherwise very great, segments 4 and 5 in achemenides, especially in the last three instars, being swollen out laterally in diamond-fashion to an enormous extent, giving the caterpillar a very strange appearance utterly unlike kadeni. The latter is almost uniformly cylindrical and of a deep cadmium yellow with black spots, while achemenides is marked with 0 white and 8 green irregular patches in lieu of the lateral oblique stripes directed towards the tail. The medio-dorsal line is represented by a series of dark marks at the interstices, and the dorsal area is defined by two irregular green lines from the face to the horn, the ground-colour being of a delicate lemon-yellow. The equally common brown variety is of course identical in form with this, but the strong combination of light and dark colour on the head and anterior segments, together with a big white square spot on the rich brown of segment 4, constitute very striking differences, and give this innocent creature the general appearance of being formidable and snake-like. MOVITATES ZOOLOGICAE XXVII. 1920. 391 In the pupa the diameter of the eye-case is distinctly less than that of kadeni, and the cremaster is shorter and blunter. 312. Leucorhampha triptolemus. (Plates 6 & 9.) R. & J. p. 381. This species, though but rarely seen as a moth at light in Para, has proved to be fairly common and widespread in the district in its larval condition, and merely needs to be searched for on its favoured food-plants, two species of Echites (Apocynaceae), growing in special localities. Its near of kin, ornatus, strongly prefers the leaves of " Pao de colher" (Zschokkea sp., Apoc), growing in the shade of the forest, but as both species occasionally take the alternative pabulum, an element of uncertainty is produced, for they are extremely alike. Indeed for some time I confused them, and in the original sketch for this article I wrote as follows : "If these names really represent distinct species, I can only say that both occur in Para, and that the line marking their specific differences is an exceedingly fine one in all stages of their being. Both, for example, feed on various species of Echites, and the moths, which to my eye only differ in the presence of a bronze-green scaling in ornatus, and more extended yellow belts between the abdominal segments in triptolemus, proceed from larvae and pupae in which I am unable to detect any distinction beyond that which is incidental ,to individual variation." Such was my view at the time, but I am now fully satisfied that the species are distinct, and while still insisting on their close relationship and great similarity, especially in the larval stage, subsequent experience enables me now to affirm : (1) that the egg of triptolemus is distinctly smaller than that of ornatus, the latter being exceptionally large, and from the outset, as it were, rightly fore- shadowing a larger and more robust insect, though to the eye the ultimate differ- ence may be but slight ; (2) that the larva of triptolemus, though identical w^th ornatus in average size, form, habits, colour- scheme, and essential markings, is generally browner and more heavily marked ; (3) that triptolemus has a plain, lemon-coloured variety with light green markings, similar to achemenides but not yet noted in ornatus ; (4) that the pupa of triptolemus, while appearing identical, nevertheless differs in that it is generally smaller, has a rather finer cremaster, and, most important of all, that this cremaster under the lens is shown to be possessed of two small divergent points not found in ornatus ; and (5) that the moth of triptolemus, reverting to the question of colour and scale- distribution, is of a cooler brown shade with a minimum of green scaling, possesses a longer and finer silver streak, is less elegant and pointed in the apex of forewing, and narrower or more squat in the breadth of hindwing. The description which I now quote was written in November 1915 for the larva of ornatus, but as it applies equally well for triptolemus and must be regarded as doing double duty, I prefer to insert it here. The larva is quite one of the most remarkable of living creatures that I have ever seen, a perfect Aaron's rod, combining in the most novel and striking way the principles of protective resemblance with an aggressive snake-mimicry. When at rest as an adult caterpillar, it hangs by two pairs of claspers in the vertical from the stem of its food-plant, and appears to be nothing but a broken branch covered with a dull, creamy white lichen. A strange black chequered dorsal design, with a 392 NoVITATES ZOOLOGIOAE XXVII. 1920. gradual intensification of the grey on certain segments completes the deception. The wonder, however, is if possible exceeded when, on being disturbed, this marvel of creative evolution endeavours once more to deceive by turning into a snake, and in quite a different way to that adopted by Xylophones or even by its fairly close relative Madoryx pluto. Though this wonderful transformation wants to be seen in life to be fully appreciated, I may explain briefly that the effect is produced by the creature turning itself over and exhibiting its ventral area, which is adorned by a broad band of dark olive-green with the three anterior sets of claspers completely withdrawn and scarcely visible. The thoracic seg- ments, which are always swollen, become puffed out laterally to an exaggerated extent ; a pair of black eyes on segment 4, hitherto concealed and situated behind the now recumbent and wholly inconspicuous legs, open out ; the cheeks appear to be adorned by yellow scales with black edges ; and the fraudulent notion that one is beholding merely the head and neck of a formidable, if small, snake is carried to a nicety by the rigidity of the curve adopted. Then, as if to mesmerize, a swaying side-to-side motion is kept up for an appreciable number of seconds, before the creature, seeming to realize that an attack is no further contemplated, gradually closes its false eyes and relapses once more into diurnal slumbers. That this mimicry of the fore-part of a small serpent, if mimicry it be, for it is hard to give it any other name, should be chiefly produced on the ventral surface, a feature peculiar in itself, and that every detail should so contribute in perfecting the deception, is altogether remarkable. • Prior to pupation the lighter tones of the larva turn to orange. It then spins a moderate cocoon among debris, and changes in three days to a uniformly dark and glossy pupa. My first specimen (of ornatus) at this particular period produced, to my utter disgust and disappointment, 72 writhing dipterous maggots, the presence of which it was impossible to foretell, as the demeanour of their over-burdened host was in all respects normal and it bore no external defacement. I naturally had no peace until I had explored the matto far and near for its food-plant and tracked down my larva once again. Length of proboscis in male moth li in. 314. Leucorhampha ornatus. (Plates 6 & 10.) R. & J. p. 382. Though not really scarce in the larval stage throughout the humid and shaded parts of the matto, it is rarer than the preceding species, and I never remember to have seen this particular moth at the electric lamps of Para, which can scarcely fail at times to attract it like its congener. For a full descrijjtion of this species and its intimate relationship with triptolemus, it is necessary carefully to study the foregoing. It is there apparent that one general account must suffice for the adult larvae of both species ; and though there may be many small points of specific difference which I have overlooked, I believe I am not far wrong when I assert that the descriptive notes of the earlier instars of ornatus given below apply very closely in detail to the corresponding stages of triptolemus. After my first accidental find of a stung larva I discovered empty egg-shells on Zschokkea, and full ones later on on a kindred Apocinaceous species (sp. ?) NOVITATES ZOOLOGICAE XXVII. 1920. 393 with a free-flowing white la^ex. These first tiny larvae had obviously perished soon after emergence. I then procured similar eggs on the near relative of Echiles known as Am- blyanthera versicolor, but these were filled with the minute grubs of hymenopterous parasites. Ultimately I succeeded in rearing this highly interesting and remarkable caterpillar to its moth from a single big green egg, found on the under-surface of a young fresh leaf of the first-named plant, and the process has several times been repeated since. The notes that I then made are worth recording, for they well exemplify the extraordinarily rapid growth and develop- ment which takes place in very many species in this part of the world ; the entire cycle of changes' from the hatching of the egg to the formation of the pupa being exactly 24 days, while 18 days more sufficed for the production of a perfect female moth. Green egg developed band of crimson 2 days before hatching. December 19, 1915, at noon, plain light green larva emerged, tail shortly becoming red-brown and mobile. Alimentary duct visible as a medio-dorsal line. Did not appear to eat much beside egg-shell, but grew appreciably and prepared to moult on evening of December 21. December 22, at 10 a.m., moulted, first instar having been passed in the remarkably short period of 72 hours. Colour soon changed to grey-green, and by 8 p.m. on December 23 was of a glossy pale maroon. Undersurface dark, dorsal area graduated from light to dark sienna. Tail held in trailing posture and dark at tip. Geometer-attitude first adopted when in repose. December 25, at noon, moulted second time. Colours intensified, a couple of black ocelli showing on the dorsal area of third thoracic segment, losing their intensity in the next instar, and being replaced by a much more highly elaborated pair on the ventral surface of the same segment. Tail of increased length, flattened laterally about centre. December 29, at noon, moulted third time for fourth instar. Colours more intensified, especially dark on ventral area, the snake-representation and general pattern of the adult larva being anticipated in many details. Tail like a curved knife-blade. January 3, at noon, moulted fourth time for final instar, as already described for triptolemus. Tail now exchanged for a minute light red point. January 9, at noon, exactly 21 days to the hour, light colour changed to reddish orange, and at midnight began to spin cocoon among leaves and earth. Shortly orange colour faded out again. January 12, during afternoon, pupated, the pupa resembling triptolemus, but being without the minute bifurcation at the tip of the cremaster which charac- terizes that species. Length of proboscis in male moth 1 J in. 316. Madoryx oiclus. R. & J. p. 383. Of this species I have but little to tell, having only managed to pick up a stray and not very perfect male on the pavement beneath an arc globe in one of the main streets of Para on July 8, 1912, and another perfect male at light in April 1919. However, my friend Mr. T. T. Dyer, with an increasing enthusiasm 394 Novitates Zoological XXVII. 1!I20. for studying the lamps, has had the good fortune, to take a couple of nearly perfect females, but neither of us have yet learnt anything about its early habits or its larva, which is doubtless as weird and snake-like as its relatives. From its apparent intimacy with bubastua, it is not improbable that it is a Tecoma feeder ; but with such a labyrinth of green as we possess in these parts, one can only deplore the lack of that precise knowledge in regard to its particular tree and locality, which, for the time at least, bars all further progress. Length of proboscis in male moth 1J in. 317. Madoryx pluto. (Plate 6.) R. & J. p. 384. This species can hardly be described as common in Para, but I have secured a good series of the moth in both sexes from electric lamps and bred a few others from larvae obtained on four or five occasions. The short descriptions of the larva and cocoon given in the Revision on pp. 383 and 385 are quite correct. I am very sceptical, however, when I see it described as a feeder on Jussieva (Onagraceae), of which we possess many varieties, ever serviceable to Pholus fasciatus and cams, but not one that would ever provide sufficient space or pro- tection on its stem for the formation of the cocoon of pluto, as I have found it. Its two chief food-plants here appear to be Miconia minutiflora (Melastomaceae) and " Cafe rana " sp. ? (Vochysiaceae). The statement that its " stout chrysalis resembles that of Pseudosphinx telrio " is wholly incorrect, and should be replaced by its " long and elegant chrysalis is dead black with ochreous interstices between three of the abdominal segments." The pupa of pluto, like all adjacent species, is exceedingly nervous and lively. The larva in its final instar, if the championship among frauds be already won by the Leucorhampha species, nevertheless runs them closely, and takes a very high second place in the perfect success of those devices resorted to in first simulating the living stalk or stem of its food-plant, and then by endeavouring to terrorize one into the belief that one is gazing at an open-mouthed snake with red jaws and a couple of fierce, blue-black eyes set immediately above them. This particular effect is produced entirely on the dorsal area by the larva lowering its head towards its legs, puffing out its thoracic segments (not laterally this time), and exhibiting these wonderfully brilliant touches of external ornament which at all other times when the caterpillar is sleeping or even when it is eating or in motion are entirely concealed within the interstices of its seg- ments, and looks a perfect stick of a light brown coloration. Though I secured two photos, to take its portrait as a snake in pencil and paint was an exceedingly difficult task, for it would never maintain the attitude for a sufficient length of time, and soon got tired of even repeating the hoax for the edification of my much-impressed friends. Writing now in April 1919, this species seems to have become as rare and unprocurable as almost everything else in these parts ; and though it may seem fanciful, I cannot help feeling that the general dearth of iepidopterous life, which appears to prevail throughout northern Brazil and is noted by all friends of the soil, must be due to some widespread epidemic on a par with the influenza among human beings, and may possibly be attributable fundamentally to that same malign influence, whatever it be. In support of the view. ] mention that a number of full-grown larvae NOVITATES ZOOLOGICAE XXVII. 1920. 395 of different genera — such as Protamhvlyx, Episior, and Xyloplianes, apparently otherwise healthy and unmolested by parasites, have recently been found hanging dead from their stalks. 318. Madoryx bubastus butleri. R. & J. p. 385. This is not a Para moth, and is one of my six interlopers referred to on p. 357. Consequent upon a short visit to the West Indies in July 1915, I am able here to insert a brief note in regard to what I take to be this species, but possess now no material for comparison. (1) The moth is distinctly smaller and browner than oiclus, which, rather than pluto, it chiefly resembles. (2) The larva, though I never saw it, obviously feeds on what is locally known as the Whitewood cedar, Tecoma leucoxylon (Bignoniaceae), an abundant tree in the Islands of St. Vincent, Bequia, and St. Lucia. (3) It spins an ample web or cocoon and covers it with scraps, like pluto does, in the crevices of the trunk of that tree. (4) Its pupa is of a lighter brown than that of pluto. with light interstices, but is smaller. (5) From the frequency with which I found the old cocoons, it is obviously a common species in these three islands at least. I can say nothing of its larva, as I was only able in the short time at my disposal to procure two full cocoons, from which perfect moths emerged within the next ten days. This unfortunately occurred after a day's exploration of the ruins of St. Pierre, Martinique, and as I had no killing-bottle they both got damaged beyond repair. 320. Hemeroplanes nomius. R. & J. p. 388. A species of frequent occurrence, especially the male, at the electric arc lamps of Para, and once similarly obtained at Manaos, but as yet remains untraced in its early stages. Length of proboscis in male moth J in. 321. Hemeroplanes pan. R. & J. p. 388. Length of proboscis in male moth J in. 324. Hemeroplanes parce. R. & J. p. 390. Both these species, like the former, are known to have a wide distribution, and both occur with equal frequency and in perfect condition at the electric lights in Para. Though comparatively small moths, they are stout enough to proceed from moderate- sized larvae, and the mystery surrounding their early stages is very hard to account for. Their obviously close alliance with inuus 396 NOVITATES ZOOLUGICAE XXVII. 1920. makes it probable that they are at least among that large number of species that favour Apocynaceous plants as a food-supply for their larvae, but as yet nothing can be discovered. It is unfortunate that among our Brazilian Spkingidae, so far as my experience goes, not a single caught female of any species will ever consent to lay in captivity. Though treated with every con- sideration in my bathroom, each one in turn batters itself to pieces and dies full of eggs. 325. Hemeroplanes inuus. (Plate 7.) R. & J. p. 391. In 1912 more frequently met with than the three foregoing species as a moth at light in Para. The egg is laid upon the tender leaves of " Pepino do matto," Ambelania tenuiflora (Apocynaceae), young or small trees in open places seeming to be preferred. The larva, which I first obtained in May 1914, has been found very sparingly since by working such trees at this time of year. It is elongate in shape after the manner of Erinnyis, and not at all snake-like as in the foregoing genera. The head is large, the ground-colour plain green, and a couple of light lines from face to tail enclose the dorsal area. These lines are of a clear lemon tint on segments 2 and 12, and the sides are relieved by orange spiracles. The tail, which in the early instars is pale green with minute touches of black, long and trailed, becomes a stout, curved, and well-erected blue-black horn in the last stage. From this description of inuus it seems highly improbable that the larva referred to in the Revision on p. 387 was that of its near relative pan. Excrement small, light green, and neatly hexagonal. The pupa is of a plain and glossy dark brown, and is formed beneath a slight web on the surface of the earth after the larva has turned pink and wandered away from its food- plant. Length of proboscis in male moth § in. 328. Aleuron carinata. R. & J. p. 395. Here I have nothing more to record than the capture of a single female moth on March 24, 1917, which was attracted to the lights of my boat at Parintins, near the boundary line between the States of Amazonas and Para. The species has not yet turned up here. 331. Aleuron chloroptera. R. & J. p. 396. Evidently a rare species in Para, my first perfect moth having occurred at light in November 1915, and only six specimens having been noted since, four of them being captured by Mr. T. T. Dyer. From the habits of the three following species, I think it probable that the whole genus are Dilleniaceous feeders with preferences for particular species of Davilla. The early stages of chloroptera, however, still remain to be discovered. N0V1TATES ZOOLOGICAE XXVII. 1920. 397 333. Aleuron iphis. (Plate 7.) 334. Aleuron neglectum. R. & J. p. 398. Both species have now been fairly frequently taken at light in Para and up-river, but cannot be regarded as common here. The larvae, from their general resemblance to one another, were not dif- ferentiated at the time, and I can therefore only show one figure, which for the present must stand for both species. They were found in August and September 1914, feeding upon a comparatively scarce form of Davilla (Dilleniaceae), which is longer in leaf and less rough than the common D. rugosa, and have not been taken since. This latter plant, a kind of creeping bush which grows very abundantly at the roadside in many open sunny places, will serve as an alternative food-plant in captivity. Larvae green or brown, possessing both the enclosed dorsal area and oblique side-stripes leading to the tail. The thoracic segments are swollen out laterally, the legs on segments 3 and 4 spring from bright crimson patches, and the horn evolves from the sickle-pattern, as shown in Enyo japix, to a mere point in the last instar. The pupae are of a straw yellow like those of Isognaihus, but naturally much smaller and with less black ornamentation, and are similarly formed beneath a web on the surface among debris. Length of proboscis in male moth f in. 335. Enyo japix japix. (Plate 7.) R. & J. p. 399. Probably not rare, but only occasionally taken at arc lamps in the city. This species vies with its congener in being the smallest Sphingid in Para. The larva, which resembles the foregoing, is green or pink- brown, possessing exaggerated thoracic segments and a sickle-like tail, evolving to a mere point in the last instar. I have but twice taken it feeding on Davilla rugosa (Dill.), and once on a kindred species in June 1919. Pupa yellow with black lines on exactly the same model as the previous species of Aleuron. For the precise distinctions which obtain between Enyo and Aleuron I must refer my readers to the figures, no written descriptions having been made at the time. The great difference between the green and maroon forms rather led me to anticipate a distinct species on the second occasion. 336. Enyo pronoe pronoe. R. & J. p. 400. This is the one and only species of Sphingidae, so far as I am aware, which has been recorded for Para by others but has evaded both myself and my one enthusiastic colleague who takes any interest in the study. Unless I have mixed up my earlier specimens, now in England, with japix, I have not seen the moth, and can do nothing more than refer to the note in the Revision, p. 401. 337. Epistor lugubris lugubris. (Plates 7 & 10.) R. & J. p. 403, 26 398 NOTITATES ZOOLOGICAE XXVII. 1920. 338. Epistor ocypete. (Plates 7 & 10.) R. & J. p. 405. Both exceedingly common at light in Para, especially the former. I take these two species together for the convenience of description, and because, though undoubtedly distinct, their larvae are at times almost impossible to differentiate. With an increasing acquaintance of them both, I find it less easy, strange to say, than I once thought, to point to their essential differences, due mainly to the fact that both have a large range of variety in colour and markings. They are practically of the same size ; both have straight, thick, leaden- coloured horns, enclosed dorsal areas, and 8 or 9 oblique side-stripes directed tailwards ; both assume various greens and pinks as a ground-colour, and both feed on various species of Cissus (Vitaceae). The word Citrus on p. 402 of the Revision is unquestionably a slip or a misprint for Cissus, for surely no one is going to be audacious enough to suggest that an Epistor ever sank so low as to leave the juice of the grape and suck an orange ! On the other hand, ocypete forms an interesting connecting-link with the two former genera by its fondness for Davilla rugosa {Dill.), on which it is much more frequently found. I think also that I am right in saying that ocypete is rougher in surface, more besprinkled with white or yellow dots, and that its dorsal and lateral stripes are more clearly white and more strongly defined with a deeper tone of the prevailing colour of the individual specimen, be it blue-green, yellow-green, or a shade of carmine red. Both species have yellow-green forms bearing a mesial and a double lateral series of more or less prominent red patches evenly situated on all their segments, and reminding one much of the variation so commonly seen in the European Smerinthus populi. In the early stages lugubris is often thus or entirely pink, and generally changes later to blue-green, especially when feeding on the similarly-coloured leaves of Cissus sicyoides, known locally as " carao " or " pareira braba." On another species of Cisstis, known as " cipo puca," it is sometimes irregularly marked with red-brown on a warm green ground, and once or twice I have taken it as if splashed with black ink or tar. The larvae of both species are hardy and voracious feeders, and produce an unusually large quantity of moderate-sized and rather round moist green excrement. But few parasites have as yet been noted in association with this genus, but I once bred a single large black wasp from a larva of ocypete. The pupae are plain brown and gloss}', with long sharp cremasters and a microscopic amount of bifurcation at their tips. They are formed a little below the surface of the earth without much admixture of silk. Length of proboscis an inch or less. 339. Epistor gorgon. (Plate 7.) R. & J. p. 405. Though occasionally taken at light, this is much rarer than the two former species in Para. The disparity in shape and colour between the two sexes of the moth is a strange and misleading feature to the uninitiated. Twice only have I bred the species from larvae found feeding on Cissus sicyoides. This is like lugubris in colour and design, but the horn is dark brown and definitely NOVITATES ZOOLOGICAE XXVII. 1920. 399 curved, and the same brown colour not only borders the anal segment but bisects the anal flap. The thoracic segments, too, are more puffed out laterally. Pupa like the foregoing but bigger, with a very long pointed cremaster a slight degree more forked. 340. Epistor taedium australis. R. & J. p. 406. Of this species I can say no more than that a single male moth was taken at a Para electric lamp early in 1918, and was thought to be only a small dark specimen of gorgon. By comparison later, however, I became convinced that it was distinct. I submitted it to Mr. Preston Clark, of Boston, who declares it to be a male of taedium australis. It is doubtless a rare species here, and almost certain to be another Cissus feeder. 341. Epistor cavifer. (Plate 10.) R. & J. p. 407. From a single moderate-sized green egg found in January 1919 on Cissus sicyoides in Utinga (the Para water-works territory), I reared a small green Sphingid larva. This seemed so like many others that, up to the final instar, I did not figure it, anticipating only gorgon which I had already drawn and painted. At this stage, however, it appeared so much more elegant and in- teresting that I began to entertain hopes in regard to one or other of the rarer kindred species, and decided that at least it merited a second portrait. It then formed a typical Epistor pupa like gorgon with a long sharp cremaster, and justified my hopes on February 18th by emerging into a perfect male of cavifer, a species which I had never hitherto met with in Para. Curiously enough, during the latter part of March I secured four more young larvae of this species, feeding on a large vine-like form of Cissus in the Para " Bosque," all of which attained full growth. Then one unaccountably succumbed to some prevailing larval epidemic, while the remaining three pupated satisfactorily, as I thought. Even one of these, however, was doomed, for a week or so later it lay limp and motionless with the abdominal segments distended, and then through a small dorsal aperture in the thorax there appeared the unholy dark form of a dipterous cocoon. From the second or third instar these larvae were very distinct from lugubris and ocypete, and shared the characters of gorgon, viz. more swollen thoracic segments, irregularly edged on approaching the ventral area with dark brown. Furthermore, the anal segment was ringed and the flap bisected with this same colour, and the horn, especially in the last instar, was a perfect hoop, very long, immensely curved, and of a dead sepia tone. It may be mentioned here that this somewhat striking and unusual ornamentation of the anal segment, apart from the horn, which is so pronounced a feature in cavifer and gorgon, is not infrequently, but only vaguely, foreshadowed in pink in lugubris and ocypete in those yellow-green forms possessing a strong consecutive series of pink spots. At this stage also the spiracular area, especially on segments 6 to 10 inclusive, is beautifully adorned with a nondescript light brown design on a delicate apple- green ground ; and though the oblique side-stripes lead up to the horn, they are bowed and not strongly delineated, while the dorsal area is inversely marked 400 Novitates Zoolooicae XXVII. 1920. with a series of V's pointing headwards. I find now that I figured this larva from a specimen taken in the Interior of Peru in 1909, but as I failed to rear the moth the figure remained unidentified and consequently unpublished. I have never consciously seen the moth at light, and can only regard it as a rare species hereabouts. 353. Nyceryx coffeae. R. & J. p. 417. A single and very perfect specimen of a beautiful Hawk-moth, quite new to my eye, has suddenly turned up in Para. I took it from the wire of a bright electric arc globe opposite my house at midnight on May 25, 1919. 365. Perigonia pallida. R. & J. p. 425. Fairly common as a moth at light in Para. Larva probably a Rubiaceous feeder, but all efforts to trace its early stages have so far failed. 367. Perigonia lusca f. restituta. (Plate 7.) R. & J. p. 426. Generally common at light in Para, and often found burnt in the debris from broken arc globes. Larva uniformly cylindrical, plain apple-green or white-green, with very narrow white mesial stripe. The head is blue-green and the horn only slightly curved. The last of the 7 light oblique side-stripes leading to the horn is, as in the case of so many species, though not in the genus Epistor, heavily edged with dark green above and sometimes touched with black. This and the suc- ceeding species of Eupyrrhoglossum and Sesia share a feature in common which is calculated to terrify away intruders. I refer to a certain strained attitude sometimes adopted, these larvae when disturbed throwing their heads back and exhibiting large lunules of velvety black in cadmium or lemon-yellow settings on the ventral area of the second and third thoracic or leg segments. At all other times these markings are completely hidden. The larva of lusca feeds sometimes on Ourouparia guianensis, but more often on the leaves of two species of coffee, Coffea arabica and liberica, all Rubiaceous plants. The pupa differs but little from Epistor in appearance, or in the position chosen for its formation. 371. Eupyrrhoglossum sagra. (Plate 9.) R. & J. p. 430. A rare moth in Para, though apparently a common species elsewhere, with a very wide range of distribution. Until lately I had never taken the species here, and recorded it simply on the authority of two friends, Mr. F. Ducke of the Para Museum, who captured a specimen at Pinheiro, 10 miles down the river ; and Mr. T. T. Dyer, who took another in good condition at a lamp in the city on March 5, 1919. On April 21, however, I had the good fortune to procure a single larva Novitates Zoological XXVTl. 1920. 401 of this species feeding on Sabicea aspera (Rubiaceae), or, to be more accurate, preparing for its penultimate moult on the underside of a Miconia leaf, which was obviously not its food-plant. This produced a perfect moth on May 12, 1919. On the completion of its ecdysis, I found that this was another species which I had figured in Peru, but that as it subsequently died it remained un- identified. I have made two new figures, and am now practically certain that yet a third Peruvian illustration of a larva with the same general bearings, but green and stouter, can only be referred to that of its congener, E. corvus. This latter species, however, is not a native of Para, and the figure remains unpublished. The larva of sagra in the fourth instar is of a warm brown, with the customary 7 dark oblique side-stripes and 4 light red patches below these stripes on segments 8, 9, 10, and 11. The horn is much erected, curved back, and then turned up. In both this and the final instar it is extremely rough and file-like on the upper edge, and disproportionately so about the middle of the lower edge, terminating in a sharp black spike. In both also segment 2 is pointed, and forms a cowl for the head. The chief differences in the last stage are as follows : colour intensified to brown madder, dorsal area light pink, latter portion of mesial stripe deep maroon, light bordered and broadened about the centre ; bent stripe on thoracic segments and a distinct mesial line marking the ventral area ; patches of colour on segments 8-11 now emerald-green and white, suggesting the figure 5 four times repeated, one green spot on 7 and a patch of green dots at a higher elevation below the stripe on 12 ; spiracles light red ; legs ochreous, on segments 3 and 4 springing from yellow-ringed black patches ; a dark tract behind horn to anal flap ; horn very rough as before on upper and lower edges, but black spike now down-turned ; the whole larval area besprinkled with minute light dots. Excrement dark brown, roundish, and the segmental divisions much obliterated. In so many ways does this species show its obvious kinship with Sesia that, were it not for certain anatomical considerations in the moth, deemed important by the expert, the clumsy word Eupyrrhoglossum might well be eliminated, and its couple of species included in that genus. 373. Sesia ceculus. (Plate 7.) R. & J. p. 433. A common species about Para, as elsewhere, but only rarely drawn to light, and more often seen, like the Humming Bird moth of Europe, flying over grass and flowers along roads and railway cuttings, and generally late in the afternoon. Two forms of the larva have frequently been met with, and so different are they in colour and markings, and so constant is this difference in direct association with food-plant, that for long I was almost convinced that they represented two species. But the resulting moths are identical in all respects, and I have now come to the conclusion that this is only a parallel case with that of P. strigilis, for example, and that neither of them admit of any specific subdivision. The difference in the colour-scheme and pattern of their larvae in these cases would appear to be purely a matter of environment, depending wholly upon the favoured food-plant, and by superficial resemblance conferring upon them a temporary protective benefit. The two plants chosen by ceculus in Para, though very different from one another, are both Rubiaceous creepers, Ourouparia guianensis and Sabicea aspera. 402 Novitates Zoolooicae XXVII. 1920. Both larvae are green, but the form found on Ourouparia is bluer, always inclines to white on the dorsal area, and never has more than the normal 7 oblique side-stripes, the first and the seventh being far more pronounced in white than the rest. The commoner variety, however, which is equally constant when found on Sabicea, though varying in the intensity of the side-stripes, now light red or maroon in colour, has always an extra bent stripe on the thoracic segments, and often the commencement of a posterior stripe just in front of the last spiracle. In this case the first and seventh stripes are hardly more prominent than the others, though the seventh always connects with the medio-dorsal line, and is sometimes supported beneath by lemon-yellow. The anal flap is, as in so many of the allied species, marked with a red-brown passage proceeding from the base of the horn. The puparium is formed just below the surface of the earth with a modicum of silk uniting dead leaves, etc., and the pupa is shorter and more dumpy than those of Epistor and Perigonia.

We come now to the last two species of the subfamily Sesiinae, which, with its 47 species or more, out of a total of not much over 120 for the world, is indeed strongly represented in Para. Though it was long before I saw either titan or jadus at all, and have but seldom since taken the moths at light or observed them during the day, my experience of a few years in the place proves that both species may be reckoned fairly common here, and that they constitute but one instance out of a number in Sphingidae where two or more species are so closely related as to be easily confused, but where, nevertheless, there is no question about their specific dis- tinction. I deal with them together to facilitate comparison. Once again the importance of the study of the early stages is emphasized, and having now been fortunate enough to work out the secrets of their life- histories, I find both species to be associated with Rubiaceae and locally plentiful in the larval condition, titan feeding on Randia formosa ("acucena"), and very occasionally upon Genipa americana (" genipapeiro "), while jadus is invariably found on the fresh leaves of the saplings of this latter tree. In both cases it is not uncommon to find three or four ova and several young larvae on the same plant, but if left too long they generally disappear, and are probably consumed by lizards. Such has too often been my experience when, for the betterment of their growth, I have trusted young larvae to nature, unprotected from its decimating forces. The larvae of both these species are of a plain apple-green colour, finely sprinkled with white dots, possessing the usual 7 oblique side-stripes, the first and seventh being the whitest and most pronounced, and the seventh containing a greater or less degree of pure pink and a touch of lemon. The mesial line is dull green and terminates with a stout, curved, and leaden-grey horn. The NOVITATES ZOOLOOICAE XXVII. 1920. 403 second and third pairs of legs in both species, as with ceculus, E. sagra, and P. lusca, spring from large black lunules set in cadmium or lemon-yellow. A handsomely variegated larva in brown with yellow side-patches, recalling the normal form of E. sagra, but with the first and seventh stripes alone clearly defined in cream-white and edged above with black, once occurred on Randia. It produced on emergence, as I had anticipated, a typical specimen of titan. The pupae, like ceculus and E. sagra, are dumpy, of a plain glossy brown, and with sharply-pointed cremasters. Though the moths are now sufficiently well known, I am bound to confess that in their larval and pupal conditions, apart from the considerations of pabula, etc., they appear to offer but few differentiating features sufficiently constant to enable one to say with absolute certainty which is which. Subfamily PHILAMPELINAE. This fourth subfamily is, so far as I can ascertain, represented in Para by but the one genus Pholus, but of the 19 species that are known, we can at any rate boast of possessing 9. Of these the larvae of 5 feed on Vitaceae, Vitis, Cissus, etc. ; 2 on Onagraceae, various species of Jussieua ; and 2 remain alto- gether unknown as regards their food-plants and early stages. Those larvae that are green invariably ripen to a deep red on their dorsal areas at full growth, wander some distance away from the region of their excrement, and form their large puparia well underground without any apparent admixture of silk. As with most Sphingidae in these parts, the moths generally appear in less than a month. The eggs are usually to be found deposited singly on the under-surface of the freshest leaves. 408. Pholus anchemolus. (Plates T.Z.S. & 9.) R. & J. p. 478. One of the commonest of the genus, both sexes frequently occurring through- out the year in Para at the city arc lamps. The immense plain green larva has a graduated series of broad oblique side-stripes, enclosing the spiracles and directed headwards. These, in increasing ratio, are situated on segments 9, 10, and 11, and are always of a clear lemon- yellow, not white, as stated in the Revision. Spots of irregular size and shape but of the same colour mark the sides of some or all of the four anterior segments. A deep vinous-coloured form with precisely the same markings is also taken here, but less commonly. It is to be found on Cissus sicyoides, erosus, etc., growing over palings or festooning trees in the shade, and up to the present in my experience it enjoys the happy reputation of being immune from parasitic attack. The pupa is of great length, of a dark red-brown colour, more glossy than fascialus but duller than vitis, and is possessed of a long, stout, and well- curved cremaster. Length of proboscis in both sexes 2\ in. 410. Pholus satellitia licaon. R. & J. p. 480. The Revision records a specimen of this subspecies taken by Dr. Goeldi at electric light in Para in March, some time before the year 1903, when everything 404 Novitates Zoolooicae XXVII. 1920. apparently was vastly more plentiful than it is to-day. I had almost begun to doubt the existence of satellitia here, but while I was away in Pernambuco during April and May 1918, my friend T. T. Dyer, without knowing it, took a larva on Cissu-s, from which he bred a perfect female of this moth, bearing considerable resemblance to a large eacus. I recognized the difference on my return, but as he had not anticipated anything new or exceptional, he could tell me nothing about the form or colour of the caterpillar. I have since taken a perfect male at light. The record is useful in proving that this species, with its immense range of distribution from Canada to Argentina, and apparently common in some of its subspecific forms in other places, is still alive here though unaccountably rare. 415. Pholus obliquus. R. & J. p. 486. Moth in both sexes fairly common at light in Para and often in perfect condition. Examination of the abdominal contents of the females of both this species and anchemolus has on occasion revealed strings of small and immature green ova, indicating that some time would have to elapse, and that probably some feeding on the part of the moth would have to take place before oviposition were possible. All my attempts to get a picture of the larva of obliquus have so far disappointingly failed. During my absence in Pernambuco, as with the previous species, my friend T. T. Dyer had another piece of exceptional luck by finding one in the shade of the Utinga matto. It was nearing full growth and feeding on the common Cissus sicyoides, consuming also the flat, trunk- clinging leaves of some Epiphite, a seemingly strange departure. He was unable to figure it, but described it as a very large and handsome caterpillar in two shades of red-brown without stripes but with a series of lighter lateral markings. After breeding a perfect female moth of obliquus, which he did simultaneously with my return, he kindly gave me the empty pupa-shell. This I may describe as practically identical in form and colour with anchemolus, and differing only in the cremaster, which is distinctly less curved, appears even stouter, and terminates with a minute but obvious fork. Though obliquus is undoubtedly a much rarer species than anchemolus, and recently (1919) has not been observed at all, that so many great larvae, especially of a species like this where the food- plant is known, should manage so skilfully to keep out of sight, is a problem which I can only explain on the supposition that they live high up in the trees or in the denser and more inaccessible parts of the forest. 416. Pholus eacus. (Plate 9.) R. & J. p. 487. A perfect female moth was taken at light in Para on May 21, 1912, and the species lost sight of till February 1916, when I discovered a full-grown larva upon an arborescent species of Jussieua (Onagraceae), probably suffruticosa or salicifolia, growing in a ditch. This was of a plain light green with 6 broad oblique side-stripes in pale yellow, faintly margined above with red, and directed headwards. At the time I took it for an extra large specimen of the green variety of fasciatus, the form Novitates Zoological XXVII. 1920. 405 which so frequently occurs in Para on the same and kindred plants, and I kept it simply on account of its size. It then turned red, and formed a pupa more like that of anchemolus ; but being busy at the time, and not anticipating anything new, it was only on the emergence of a lovely female moth of eacus on the evening of April 30 that I realized how faulty had been my observations, and how nearly I had lost a prize. Since those days eacus has been a fairly common species to me, for though but two or three specimens of the moth have been taken at light, many have been bred. While I was at Iquitos in February 1917 my devoted and sharp-witted cook found me about 16 ova and larvae, and I have generally been able to procure more by returning to the same place at the same time and during the three succeeding months. This favoured locality is known as Entroncamento on the railway-line, 11 kilometres out of the city, and here this particular species of Jussieua grows to quite a respectable small tree in the ditches, and thrives on a tract of wet white sand. Unlike its less fastidious congener fasciatus, eacus in nature appears to be restricted to this species, and does not do well in captivity when only provided with other more readily obtained varieties of Jussieua. It has occurred in two other localities, but always on the same plant. The larva of eacus is as constant as fasciatus is variable, and is always green with only 6 light stripes which are bordered above with red. Its egg, though much smaller than that of anchemolus or labruscae, is nearly twice the size of fasciatus, and rather whiter. . - With a little experience one is able to pronounce with certainty upon the difference between eacus and the green form of fasciatus ; but the general likeness between their larvae as Jussieua feeders would seem to indicate that eacus is out of place, and that in reality the two species are more closely related to one another than fasciatus is to vitis, with which it was once so erroneously confounded. Though kept from the light, this moth tends to fade more than many others Length of proboscis in female moth If- in. 422. Pholus vitis vitis. (Plates T.Z.S. & 10.) R. & J. p. 491. In regard to this already described and well-known species, I need say but little. Merely have I to record that the moth, though occasionally observed at electric lamps in Para, and perhaps a trifle larger and brighter than those which I used to breed from the vines of Lima, is here comparatively rare. Our climate is too hot and wet for the vine to flourish, and I cannot remember to have taken the larva on more than six or eight occasions when searching for other larvae on Cissus. 423. Pholus fasciatus. (Plate T.Z.S. & 2.) R. & J. p. 494. This species, too, may be dismissed with a short paragraph, as it is now so well known. The moth is very common at light in Para. Several species of Jussieua, the natural food-plants, grow abundantly in ditches and in other wet places throughout the district, and it would appear that the larva of fasciatus is at all times and in all places to be found associated therewith. Among the many-coloured varieties of the larva already figured, 406 Novitates Zoologicae XXVII. 1920. the green form with its 8 clearly-defined oblique side-stripes, comparatively rare about Lima, is here undoubtedly the prevailing form. No shade of difference can, of course, be detected in the moths, and I assume that this is but another nice adaptation to a greener and more flourishing vegetation. The egg of fasciatus is not only much the smallest of all the species of Pholus with which I am acquainted, but is probably one of the smallest of all Sphingidae, when considered in relation to the weight and bulk of the full-grown caterpillar or the size of its moth. The little light oval green egg and the tiny milk-white larva with its erect black tail which hatches from it are very similar to those of Sesia ceculus, and if anything a trifle smaller. The pupa, which occasionally produces a big dipterous parasitic fly whose presence cannot always be detected in the larval condition, differs from all the other species of Pholus dealt with in being dead black in surface, relieved by brown in the interstices of the abdominal segments, and the cremaster is short and slender by comparison. Length of proboscis in male nearly 2 in. 424. Pholus phorbas. R. & J. p. 495. 425. Pholus capronnieri. R. & J. p. 496. These two beautiful species are not infrequently drawn to the electric arc lamps of Para, the males and females of both occurring in perfect condition, and being picked up on the pavement together with hosts of other commoner moths. Times, however, have changed for the worse, and they have hardly been seen since 1917. Though I have not even yet abandoned the hope of some day finding their larvae, I have already searched hard, but with no result beyond the growing conviction that neither of them is associated with Vitaceae or Onagraceae. 426. Pholus labruscae. (Plate T.Z.S.) R. & J. p. 496. A fairly common species as a moth at light in Para, and the larva frequently taken on the various local forms of Cissus (Vit.), and once on a vine-like creeper in the Botanic Gardens, Siphania glaziovee (Menespermaceae), introduced from the Upper Amazon. My experience is that of others when I say that it is next to impossible in this hot and humid climate to prevent this lovely green moth from fading and contracting bleached or ochreous patches on wings and abdomen. I have little new to add to my notes and illustrations of the species made in Peru, and to the ample descriptions of its larva and pupa given on p. 497 of the Revision, beyond pointing once again to the marked difference which labruscae shows from all other known species of Pholus both in the larva and pupa, the latter being possessed of a very broad, rough, and flattened cremaster.

Outwardly labruscae would appear to merit a separate generic status every Novitates Zoolooioae XXVII. 1920. 407 bit as much as Amphimoea walkeri or Pseudosphinx ietrio, and even more, I venture to think, than Eupyrrhoglossurn sagra ; but from the point of view of one who is chiefly interested in co-ordinating an array of facts relating to early stages, and forming some rough estimation upon the degree of kinship between related species, the creation of new genera is a nuisance. Unless some nice point, some subtlety of scientific import in regard to generic distinction, has passed me by unnoted and unappreciated, it seems to me that the association of as many species as possible in a single genus, with here and there a slight readjustment in their sequential order or grouping, would be far more instructive than the mere multiplication of genera — an opposite process which seeks rather to emphasize differences of outstanding importance, but which, with our still very limited knowledge, is bound to be somewhat arbitrary and lacking in finality. If it be conceded that the grouping of more species in fewer genera would aid the collector in the field, it naturally follows that greater benefit would accrue to the museum student, who always wants the fullest material possible for purposes of comparison. Subfamily CHOEROCAMPINAE. This fifth and last subfamily of the Sphingidae is in Para limited to the one exclusively American genus Xylophanes ; but as its local representation out of the 50 to 60 species known already amounts to a dozen species, one being quite new and others esteemed as rarities, the interest attaching to it is well sustained. The larvae of seven species have been discovered, bred, and carefully figured in their various stages, and the remainder, as yet undiscovered, cannot be far away. It is noticeable that all but one are Rubiaceous feeders, and the inference that Xylophanes, as a compact genus, is in its entirety more or less restricted to Rubiaceae, should, if correct, materially aid the investigator of early stages by eliminating the more unlikely forms of plant-life. Most of the larvae are snake-like and secretive in habits, and some are much troubled by parasitic attack. The excrement bears specific peculiarities ; in chiron alone, of the species dealt with, being of the normal hexagonal and tripartite form. In the others it is almost or entirely devoid of this pattern and exceptionally large, while in species like mossi, guianensis, and amibus it is of phenomenal size, dark brown or blue-black in colour, and either rounded or of an irregular elongate formation. These larvae, like so many others, tone to a redder hue and lave their bodies with a frothy substance from the mouth prior to leaving the plant for pupation. In this palpably sticky condition they appear nearly always to wander some distance away from where they have been feeding, and spin a glutinous web amongst vegetation and dead leaves on the surface of the earth to form their puparia. Though the pupa of each species differs in the precise shape and form of the cremaster, and to a slight extent in tone of colour, a general type is adopted throughout, which may roughly be described as bone-coloured with a mesial dark line, more or less pronounced and continuous, marking both the dorsal and ventral areas. The region of the spiracles, themselves brick-red, is heavily spotted with black, and the entire surface is minutely freckled with light-brown or olive-green marks. 408 NOVITATES ZOOLOQICAE XXVII. 1920. 631. Xylophanes pluto. R. & J. p. 681. Of this widely distributed and common species, with which I became acquainted some years ago in the Interior of Peru, I have here but to record the capture of a single perfect male at a Para lamp near the end of March 1919. This was taken by Mr. T. T. Dyer, who is confident that he there and then missed another example of the same species, which was very strange, for its observed occurrence in this particular part of S. America is, so far as I know, without precedent. In regard to Erythroxylon, its reputed food-plant, E. coca, which is so extensively grown as a drug in other parts, is in Para a comparatively rare plant in gardens, and I have never found it touched by anything beyond a small Geometrid larva. The larva of X. pluto may subsist on other plants, but in any case it must be a very rare species hereabouts. Xylophanes mossi. (Plates 5 & 8.) Xylophanes mossi Clark (1919). In his paper on " New Sphingidae," published in the Proceedings of the New England Zoological Club, my generous friend B. Preston Clark has described this species, and been pleased to attach my name to it as its original discoverer. Strange to say, I have never yet taken it wild in the imaginal condition, but since 1914, when I found my first larva and some eggs, I have repeatedly bred the species. No definite months can be given, as I have taken or observed signs of the larva at almost all times of year, and too' often have I had the mortification of being just a few days too late, finding the plant vigorously eaten and some enormous pellets of fresh excrement lying on the ground, but the larva gone. Even when it has been found, I have by no means always met with success, as the species is so ravaged by parasites ; and I think I am fairly stating the case, when I say that I have bred from 15 to 20 perfect males and females out of some 60 larvae in 6 years, and just managed to miss about twice that number. The plant on which the larva feeds, Pagamea guianensis (Loganiaceae, or Rnbiaceae according to Dr. Huber), is distinctly local, being restricted to the particular type of sandy soil found between Souza and Tapana on the Pinheiro railway- line, but significantly absent from the adjacent Utinga water-works region. It is also fairly abundant in the Isle of Mosqueiro, and in all places where the plant grows I have traced the larva. As these localities range roughly from 10 to 25 kilometres from our city station, the distance may possibly account for the non-appearance of this moth at light. I say this advisedly, for though the Sphingidae as a family are known to be long and strong fliers, and it is beyond question that many species are thus drawn from very considerable distances, there is as yet no proof that all Hawk-moths wander far from home. And furthermore, if this be the case, it is more than probable that in the vast reaches of the tropics of this continent there are links in the Sphingid chain of life still extant, and many another species yet waiting to be revealed to science. I have already given a general description of the larva on p. 349 of the general introduction, and need only add the following : The small, down- turned tail of the adult larva is a most peculiar feature, differing from all other known species NOVITATES ZOOLOGICAE XXVII. 1920. 409 of Xylophanes ; the head is small and typical of the genus ; the tapering anterior segments by no means reach their maximum with the ocelli on the 5th segment, as is so often the case, but only with segment 12 which appears enormously swollen ; and, finally, this stout caterpillar, whether it be of the normal pink and burnt sienna coloration with its 5 viridian-green side-patches or green-grey with 7 lemon-yellow side-stripes, is distinctly Pholus-\ike in appearance. The frass is enormous, blackish brown, rounded or of regular oval form, and tightly packed in thin successive layers. Seldom are more than 8 pellets dropped in the 24 hours. The growth is, nevertheless, extremely rapid, the last instar never exceeding 5 days, and the whole larval period being generally under 20. The pupa is typical of Xylophanes but rather redder than most, and it is possessed of a long, blade- like cremaster. In regard to the parasitic attack to which this species is so lamentably prone, I have five observations to make : ( 1 ) The egg is sometimes stung by a minute hymenopterous fly. (2) A dipterous fly stings the young larva while it is still small, generally in the second or third instar, I believe. (3) Neither then nor in the succeeding instars is there any apparent sign of the presence of the foe within, no lack of vitality observable in the larva, no irregular feeding, and no protracted growth, as is often the case, and nothing irregular in its colour or in the nature of its excrement. (4) After spinning its puparium the larva invariably, whether healthy or otherwise, produces an abundance of brown slime in which it lies. When it is stung, however, it begins to look limp, and exhibits irregular brown stains on the second day. (5) The larva is just alive on the third day and capable of feeble movement, but the dipterous maggots, in this case generally less than 10 in number from any individual, emerge from the body of the host to form their own cocoons separately in the soil. This occurs invariably on the evening of the third day, and precisely at the time when the larva, had it been healthy, would have cast its final skin and become a pupa. Repeated instances confirm these observations in every detail, and the accuracy with which the whole process is timed is little short of marvellous. Many Sphingid larvae, as already stated, lave their bodies with a sticky substance prior to pupation, and other species of Xylophanes make what we should call a mess of their puparia, but none, so far as I am aware, to a like extent. What particular purpose the froth or slime serves is not apparent ; it may be to assist ecdysis, or it may be to prevent the intrusion of small forms of creeping life at a period when both larval and pupal skins are peculiarly sensitive and liable to damage. 638. Xylophanes porcus continentalis. (Plate 8.) R. & J. p. 685. Dating back to March 1912 when I found my first larva, and to the next three years during which I secured but half a dozen more, I esteemed the species rare in Para. Since then, however, though only one moth of porcus has been recorded at light, I have so repeatedly taken its egg and the young or full-grown larva on fresh saplings of Palicourea grayidifolia (Bubiaceae) in such localities 410 NOVITATES ZOOLOGICAE XXVII. 1920. as Utinga, where this plant thrives in abundance, that I regard it now as almost the easiest species of the genus to obtain hereabouts. Its food-plant is of wide but not universal distribution, growing in the shaded matto on the north a«d eastern outskirts of the city, but being apparently absent in the muddy region which borders the Rio Guama. The eggs of porcus are generally deposited singly upon the upper side of the tenderest yellow-green leaves of the plant, and throughout its growth the larva is to be found on the under-surface of half-consunied leaves, clinging firmly to the mid-rib, never on the stems or the earth. It is always of a pure apple-green colour, with small light caerulean blue ocelli on segment 5, and 7 yellow side-stripes leading up to the horn, which is plain pink, smooth, and well curved. The pupa is typical of Xylophanes, though somewhat more olive-green in tone, heavily lined with brown, and possesses a shorter but broader blade-like cremaster than the foregoing species. Length of proboscis in female moth 1|- in., in male 1 in. 651. Xylophanes guianensis. (Plates 5 & 8.) K. & J. p. 692. This species, like the former, has, strange to say, only once been observed as a moth at light in Para, but from the numerous occasions in at least seven different months when I have taken the larva on Palicourea grandifolia (Rubiaceae), or the egg, readily detected on the upper- or under-surface of its large, flat leaves, I am bound to regard it as by no means rare here. The larva up to the end of the fourth instar is long and thin, and being of the same colour as the upper surface of the leaf, a sage- or blue-green, it always reposes during the day in that position along the mid-rib and is easily passed over. At this period the dorsal area is enclosed by a couple of yellow longitudinal stripes, terminating in a straight, recumbent horn, adorned with small black tubercles. In the last stage the enormously long pellets of blue-black frass beneath the tree frequently betoken its presence, but now having assumed a very dark vinous-brown colour, the larva is only to be found on the trunk, generally at the base in heavy shade, or even several feet away from it, resting on a stick or on the soil among dead leaves. The eye readily detects its characteristic bite, especially when the tree is small and the leaves very large and not too numerous. From Mr. Schaus's description of the larva of ceratomoides, its next-of-kin, it would appear that guianensis corresponds pretty closely. A plain ochreous spot or two represents the ocellus on segment 5, and it possesses a long, stout, and perfectly straight blade-like horn, which is saw-edged above and below, and terminates in a spike. The cremaster of the pupa is similarly large, flat, and broad, and spiked along its angled extremity. The species is sometimes troubled by dipterous parasites. Length of proboscis in male 1J in. 652. Xylophanes anubus. (Plate 8.) R. & J. p. 693. Quite a common species in Para, as elsewhere, judging from one's success with its larva, but once again, like the three former species, very seldom is it NOVITATES ZOOLOGICAE XXVII. 1920. 411 drawn to light here. Indeed, throughout my time in Para I have only twice come across the moth, one being taken in a strong cobweb, and the other, a female in almost perfect condition and of a peculiar chestnut colour, especially in the hindwings, being picked up dead in the Port of Para Buildings in May 1915. So different did this appear from all my bred examples, which are umbrous inclining to olive, that, until Dr. Jordan had examined it, I was of opinion that it was something distinct. I may here add that this suffusion of a delicate olive-green in all my Para-bred specimens was never noted in those caught in Peru, which always seemed browner and more heavily lined. The larva here feeds on a couple of species of Palicourea (Rubiaceae) with dark glossy leaves, the bigger of the two growing in dry and open parts where the forest has been cut down, the other, a more slender plant, being invariably associated with the sides of streams and boggy ground. Up to the end of the fourth instar the larva is of a pallid and subdued green, like the under-surface of the leaves referred to, and where during the day it constantly remains. The fifth segment is now considerably swollen, and its ocellus at this period is large and striking, a finely pencilled black ring containing a patch of lilac and an arc of pure light blue in front. Its tail, once long and drooped, is now and up to the end of its larval stage an ample and well-curved horn. In the last stage, like guianensis, antibus is brown, and invariably remains during the heat and brilliance of the day on the brown stems in the shade near the ground, or more often actually on the ground beneath dead leaves. The ocelli, which are now black in fine blue rings, are proportionately reduced, the dorsal area is enclosed by rufous and dark lines from head to horn, and the side-stripes are represented by 7 rather obscure and waved lines in moss-green directed tailwards. At this stage I have very frequently taken it, once the secret of its whereabouts was disclosed, but, as with mossi and guianensis, I suppose I have equally often been just too late, and experienced the keen disappointment of finding only stripped branches and an abundance of fresh frass. This again is enormous, but of umber or dark brown compared with that of the preceding species. Though I have often pulled up everything alive or dead for yards around, and raked the ground till I have dripped with perspiration, I have never been able to trace this or any other species of Xylophanes but tersa to its puparium in nature. The pupa is lighter and more slender than guianensis, with a blacker medio- dorsal line and a much finer cremaster. The species is occasionally troubled by diptera, and I once bred a single blue- black wasp from a large white hymenopterous grub which emerged in the puparium from the body of a dying caterpillar. Length of proboscis in male moth If in. 654. Xylophanes amadis goeldii. R. & J. p. 694. In this little-known form of amadis, Para exhibits one of the prizes of its rich and variegated fauna. In the Revision there is but one record of a female having been taken at electric light in Para during the month of May by Dr. Goeldi, and sent to the Bern Museum. In July and August 1912 I had the good fortune to take three males here in the same way. My next find was that of a 412 Novitates Zoolooicae XXVTI. 1920. perfect female on a lamp in front of the Museu Goeldi in December 1916, and this I sent to Mr. Preston Clark, together with a male caught by Mr. Dyer in 1918. I then missed a male which had perched up at the top of a high lamp- post in January 1919, and my friend did the same towards the end of May. On March 28th of this year, however, I managed to secure another freshly-emerged female in very perfect condition on a lamp almost opposite my house in the Largo de Baptista Campos. In stuffing her long and narrow abdomen with wool, as a precautionary measure, I extracted 78 green eggs of moderate size. Diligent examination, oft repeated, of the Rubiaceous plants favoured by amibus and others, has so far completely failed to reveal the larva of this elegant species, which, although rare, is, from the above records, obviously well established in Para, and would very likely be found to exist here in some numbers, could one but unravel the secrets of the early stages of its life. Length of proboscis in female moth 2 in. 655. Xylophanes epaphus. R. & J. p. 696. My general remarks on the previous species apply equally here, no larva or knowledge of food-plant or early stages having rewarded the repeated examination of all likely plants in the Order Rubiaceae. To know the habits of epaphus would be to discover a veritable gold-mine, for its food-plant is hardly likely to be anything more pretentious than some humble ground-weed like Spermacoce or Psychotria, growing in some particular shaded or even wet locality, and the find of a single caterpillar would almost certainly lead to the discovery not only of amadis but of kindred species like docilis and cosmius in their respective regions. This, however, has not yet been accomplished, and all I can do is to record the following captures of the moth at light in Para, all males, I believe, and all in nearly perfect condition : one at Mira Mar, three miles down the river, in March 1912 ; two on the walls of the S. Braz market in June of that year ; another subsequently taken by my friend T. T. Dyer in 1917, and the last falling to me in January 1920. It will be noted that many of my records date back to 1912, which, though so wet, rain falling on 323 days, was by far the best year I have yet experienced in Para or elsewhere for Sphingidae. I find that I recorded 66 species between April 8 and July 31, and no fewer than 51 in the first 53 days of that period. 658. Xylophanes chiron nechus. (Plate 8.) R. & J. p. 697. One of the most showy of the genus in Para in its livery of emerald-green — a sadly fugitive colour — and at the same time one of the commonest, the moth Xylophanes cosmius. R. & J. (1906). Of this rare species, I became the lucky possessor of the first female known, a large specimen with a broad forewing considerably hooked at the apex, and in absolutely perfect condition. This was taken by a Mr. Hammerton in his house at Manaos in 1912, who most kindly gave it to me, and it is now in the Tring Museum collection. Novitates Zoolooicae XXVII. 1920. 413 frequently occurring at electric lamps. The larva is often found on Palicourea grandijolia, on various species of Psychotria and Spermacoce, all Rubiaceous plants, and, by way of showing an independence from the general rule adopted by its genus, has also several times been found on plants belonging to the Order Icacinaceae. The rather small green egg has often been found on such plants, and the little glossy green larva resulting from it, with its comparatively slow growth, has often received the greatest attention, leaving me in suspense as regards its identity for a considerable time. In the early instars the marks are faint, the skin thin, glossy, and semi- transparent, the muscular tissues clearly visible, and only the last two or three side-stripes indicated very obliquely tailwards in a lighter key. In the third and fourth instars its identity is unmistakable, a couple of ocelli adorning each side. In the last stage these white ocelli in their crimson rings, finely outlined in black, on segments 5 and 6 which are swollen, constitute a special feature. A rather more elongate patch of lemon-yellow in some examples, but not commonly, similarly adorns segment 7, and the customary dorsal area enclosure is suggested by an interrupted series of three yellow spots on each succeeding segment. The band leading up to the horn is always the most pronounced in yellow or white, and is strongly edged above with black. There is also a fine but much interrupted medio-dorsal black line or series of black marks, the indication of some 5 side-stripes of a lighter hue than the ground-colour, which develops from plain green to a very light blue-green tint. The horn, which is long in early days and light- tipped, becomes stout in the last instar and terminates with a sharply down-turned black spike. This is grey at the sides and roughened with pink tubercles above and below. The legs are pink and the spiracles light. The larva tapers considerably to the head, and while laving itself with a sticky froth prior to pupation completely changes in colour, turning to an olive-brown with a prominent black patch or two on each segment. The pupa is of the normal Xylophanes design and colour but exceptionally long in the head-piece, and possesses a rather flat and well-developed cremaster, which is, nevertheless, pointed and insignificant compared with those of the foregoing species. Several varieties of dipterous parasites associate themselves with the species, and from a large and apparently healthy pupa I recently bred a single fly with the dimensions of a blue-bottle. Length of proboscis in female moth 2 in. 664. Xylophanes tersa. (Plates T.Z.S.) R. fe J. p. 703. Little more need be said of this species beyond recording the fact that it is normal in Para, as elsewhere, and as common at light as it is known to be in other parts of the continent. The larvae frequent several species and allies of Spermacoce (Rubiaceae) at roadsides and on the banks of ditches, etc., and 1 once induced one to eat a vine leaf. Though often dark brown, they are here as frequently of a blue-green tint like the leaves, and are then generally to be found by day on the green 27 414 Novitates Zoolooicae XXVII. 1920. stalks. The frass is often light green and lined, but very irregular in size and form. The pupa is distinguished by its sharp and narrow cremaster, and generally has much black on the wing-cases. The moth when at rest, in common with other species of the genus, holds its narrow wings spread out at a wide angle. Length of proboscis in male moth 1J in. 667. Xylophanes elara. R. A J. p. 704. This appears to be a distinctly rare moth in Para, only two perfect specimens having occurred at light in 1912, one being recorded for the month of August. Like loelia in size and shape, it is characterized by its delicate sage-green colour and a small dark orbicular spot in the centre of each forewing. It can hardly be other than a Rubiaceous feeder, and is probably nourished on some form of Spermacoce, but here once again the early stages remain to be discovered. 675. Xylophanes loelia. (Plate 8.) R. & J. p. 710. A species resembling a fawn-coloured but less strongly marked edition of tersa, with salmon-pink instead of yellow on the hindwings, and almost equally common at light in Para. The larva, which is green when young, with a couple of yellow lines enclosing the dorsal area and a straight horn, becomes ochreous-brown with a series of dark spots to mark the mesial line, and terminates with a prominent dark and distinctly curved horn in the last stage. Some 5 or 6 dark-brown side-stripes are visible, and the dark lines which now enclose the brown and spotted dorsal area are interrupted on segment 5 with a light and dark ocellus, half hidden in the skin- fold and giving the creature a distinctly wicked and deadly appearance, more so than in the case of tersa. It feeds on several varieties of Spermacoce (Rubiaceae), which literally cover many of our grassy travessas ; and, like other species of this genus that are secretive and hidden by day, the larva is best obtained by exploring such regions with a lantern after dark, when it is usually to be found high up on the extremities of the plant, and is readily detected among the small green leaves. 672. Xylophanes maculator wolfi. R. & J. p. 707. A species unknown in Para, and the last of my six extras. On March 7, 1917, during my week's stay at Iquitos, I had the good fortune to take the first female known of this rare Peruvian subspecies. I found it by day on the wire gauze covering the verandah of the house of Mr. and Mrs. Harrison, with whom I was stopping. The moth was in perfect condition, and thinking that it might possibly be a new species, I sent it to my friend Mr. Preston Clark, who identified it as above. Novitates Zoologicae XXVII. 1920. 415 The pupa, though like tersa, has a lighter dorsal stripe and much less black on its wing-cases ; the sharp-pointed cremaster, too, is longer and stouter. Length of proboscis in male moth nearly H in. 677. Xylophanes thyelia. R. & J. p. 711. Of this closing species, which was moderately common at light in Para in 1912 but only occasionally seen since, I have once again to confess my ignorance of its larva, and regret my inability up to date to record anything of its early d d j. a O OH CQ 9 B u _ Ph P, >i _ C 3 £ a i ft O i3 03 > o W g 3 O O H P-l eS O c3 • !_=.*_■ C ® C! o »o ftSJ > » =» § 0J ~* <» ■S - a a -a" .o O d g T3 03 -C 2 ST** a s » o o o If! a « O B d ' O O O tH • 3 a ' to § ri ft j^^-a ■». to o ' ,9'S- O o : 45 « !

Maurice de Rothschild leg. Swainson, instead of " Telephonus." Thereupon Reichenow, Orn. Monatsber. 1907, p. 99, pointed out that Swainson's Telophonus 1837 was obviously only an amended spelling of the same author's Telophorus of 1831, a name which had been overlooked. I quite agree that, therefore, Telophonus is no more acceptable than Pomalorhynchus, and use Harpolestes Cab. 1850 for this genus. Sclater and Mackworth-Praed {Ibis, 1918, p. 636) use the generic " Tsrhagra," but Tschagra of Gray is obviously only another spelling of Tchagra Lesson. Traitt d'Orn. p. 878, which I take to be a new name for Laniurius Vicillot, though Lesson included in the same subgenus Levaillant's Tchagra and a number of other species. | NOVITATES ZOOLOGICAE XXVII. 1920. 451 514. Pelicinius zeylonus phanus subsp. nov. Type : ^ ad., Farta Bay, 5 hours south of Benguella Town, 30.x. 1905. W. J. Ansorge leg. Seven specimens from Benguella and Mossamedes, collected by the late W. J. Ansorge and Albert Mocquerys, differ from about a dozen from South Africa in having the back a little paler green, and the whole yellow portion of the under- side much lighter, more sulphureous yellow, which is specially striking on the throat, abdomen, and under tail-coverts. There is no appreciable difference in size. I therefore name the Benguella-Mossamedes form Pelicinius zeylonus phanus, type as above. Probably a third form inhabits Namaqualand, as a male and female collected by C. B. Grant in May and July 1903, at an elevation of 3, 104 feet, appear to have the flanks and sides of breast much more widely ashy grey, and are a little smaller. More material will probably lead to the establishment of a third form. (I am using reluctantly the generic name Pelicinius, while I separate cruentus and its subspecies as Rhodophoneus. In this I am following Sharpe's Hand-list, iv. pp. 292, 293, without wishing to discuss the genera of these shrikes, of which perhaps too many are now being used. ) 515.

There is no doubt that the adult male must be looked upon as the real type of L. gubernator, but the notes in Journ. f. Orn. 1882, pp. 323, 324, are somewhat confused. The first diagnosis in the Ornithologische Centralblatt is that of the adult male only. Curiously enough, in the Journ. f. Orn. also the male only is . 452 NOVITATES ZOOLOOIOAE XXVII. 1920. described, though at the end of the description, p. 324, stands " $ ad." On the plate the male only is figured, and this agrees with the lettering of the plate, but on p. 323 it is erroneously said that the figure is that of the female ! On p. 324 Hartlaub wrote that four specimens were obtained at Langomeri, an adult male and female, and two young birds. We have all these four in the Tring Museum, and the sexes are correctly stated on the labels. The female, which has no black frontal line, was not described by Hartlaub at all, though he says, " Zunachst erhielten wir nur das ausgefarbbe Weibchen " ! I suppose he meant to say " Mannchen " instead of " Weibchen," and that the " $ ad. " at the end of the description of the male means that it was the author's intention to describe the $ as well, which, however, he did not do. f 519. Lanius excubitorius intercedens Neum. = Lanius excubitorius excubitorius. Lanius excuhitorius intercedens Neumann, Journ. f.

Oscar Neumann leg. No. 250. Neumann compared his bird with L. excubitorius princeps. which he thought were L. excubitorius excubitorius, and his intercedens are typical excubitorius. 520. Lanius antinorii mauritii Neum. = Lanius antinorii mauritii. Lanius antinorii mauritii Neumann, Journ. f. Orn. 1907. p. 595 (Koroli Mountains, West Somaliland). Type and unique specimen : ad. (not" J "), primeval forest west of Baraka, 1,900 m., l.xii.1908. , Rud. Grauer leg. No. 3,819. This form requires confirmation. The type is very pale, but in the same region we find quite dark birds like cinnamomeus. 609. Stasiasticus montis Hart. = Bradypterus montis. Stasiasticus montis Hartert, Nov. Zool. iii. p. 540 (1896 — Mt. Arjuno, Eastern Java). Type : Mt- Madang, 3,000 feet, September 1898. J. Dumas leg. The young bird was not fit to show the real affinities, but Stresemann obtained an adult female from Mt. Fogha, 4.500 feet high, on Buru, which proves to my mind that disturbans is a subspecies of A. castaneus. 731. Androphilus disturbans museums Stres. = Androphilus castaneus musculus. Androphilus disturbans musculus Stresemann, Nov. Zool. xxi. p. 136 (1914 — Middle and West Ceram). Type: $ ad., Goonoong Pinaia, Middle Ceram, 7,500 feet, 18. viii. 1911. Erwin Stresemann leg.

Argya sharpii Ogilvie-Grant & Reid, Ibis, 1901. p. 662 (Shebelli). Type : <$ ad., Shebelli, 27.viii. 1894. Dr. A. Donaldson Smith leg. No. 201. Though much larger, this specimen agrees in other ways perfectly with Crateropus (Argya) rubiginosus rubiginosus, and it was rash to describe it as " new species " from this one specimen. Without further material it cannot be ascertained whether this is a distinct subspecies or an exceptionally large specimen. 734. Crateropus caudatus altirostris Hart. = Crateropus (Argya) altirostris. Crateropus caudatus altirostris Hartert, " Vog. pal. Fauna, p. 623 (1909 — "An der Nordspitze dea Persischen Golfs, au der Miindung des vereinigten Euphrat und Tigris "). Type : Fao, 1893. W. D. Cumming leg. Though very much like C. (Argya) caudatus hitttoni, this form must be regarded as a separate species, because a form of C. caudatus occurs together with it, in the same region. 735. Crateropus plebeius kikuyuensis Neum. = Crateropus plebeius kikuyuensis. Crateropus plebeius kikuyuensis Neumann, Orn. Monatsber. 1906. p. 7 (" Kikuyu "). Type : $ ad., Escarpment station, Kikuyu Mts., February 1901, 6,500 feet. William Doherty leg. This form is very closely allied to C. p. emini Neum. from " Uniamwesi, Lander am Tanganyka, Tabora, Usagara," but is slightly darker. It is also close to C. p. hypostictus from Angola, but the latter is distinctly lighter in colour. 736. Crateropus smithi lacuum Neum. = Crateropus levcopygius lacuum. Crateropus smithi lacuum Neumann, Bull. B.O. Club, xiv. p. 15 (1903 — " The Lake Valley south of Shoa, from Lake Zuai to Lake Gandjule, and the mountain-slopes east of that valley "). Type: S a(i.> Alelu, north of Lake Abassi, 9.xii.l900. Oscar Neumann leg. No. 331. 737. Crateropus smithi omoensis Neum. = Crateropus leucopygius omoensis. Crateropus smithi omoensis Neumann, Bull. B.O. Club, xiv. p. 15 (1903 — " The countries of the Omo System — Uba, Gofa, Doko, Malo, and Kaffa, and also the head-waters of the Gelo River, Binescho and Schecho "). Type: J ad., Senti River between Uba and Gofa, 30. i. 1901. Oscar Neumann leg. No. 713. (Cf. also Journ. f. Orn. 1904, p. 553, 1906, pp. 261, 262.) C. I. lacuum is nearest to C. I. smithi and stands between the latter and omoensis, but is constant and well distinguishable from both. Only one specimen of C. I. lacuum, No. 391, approaches C. I. omoensis. 738. Crateropus tenebrosus Haiti. = Crateropus tenebrosus. Crateropus tenelirosus Hartlaub, Journ. f. Orn. 1883. p. 425 (Kudurma) ; id. Zool. Jahrb. 1897. p. 313. Type: $ ad., Kudurma, S.E.

Orn. 1904, p. 552, says : " Diese Art ist sicher der geographische Vertreter des C. melanops." I am not so sure about this, and should like to leave the question open. C. tenebrosus is still extremely rare. All specimens known in collections are four in number : the type in Tring ; 2 speci- mens collected by Donaldson Smith at Fort Berkeley ; 1 Mt. Baginzi, Bahr-el- Ghazal, Christy leg. Mr. Butler (cf. Ibis, 1918, p. 695) says that it is " quite a common bird in the vicinity of Kajo Kaji, in the Lado Enclave," but he does not seem to have collected a single specimen. 739.
