234 MEGAXOTOX; PSILOGRAMMA. By Dr. K. Jordan. 



3. Genus: Mej^i^aiiotoii Walk. 



A pun-lv Oriental gemi.s comprisintr four s])ecies, two of which oecur in our area. Large ; tongue very long, 

 longer than the body. Antennae long and slender, terminating with a long thin hook. Palpi large, segment 

 2 nearly as broad as it is long, when seen from above with a broad end-surface. Legs long, tibiae without spines, 

 but with long spurs, the longer apical spur of the hind tibia about three-quarters the length of the tibia; middle 

 and hind tarsi with long basal bristles, hind tarsus more than twice as long as the anterior edge of the cell of 

 the hindwing; fore tarsus witliout prolonged bristles. Pulvillus and paronychium present, the latter having 

 two lobes on each side. The claspcr of the o has a patch of friction-sc-ales on the outer side. Larva and pupa 

 known of only one species {nyclip/innes): the former with S-shaped curved granulose horn (similar to that 

 of Acherontia); metathorax with conical median hump. Tongue-case of pupa free, curved, but not curved 

 frontad spirally as in Herse. 



analis. M. analis Feld. (36 c). Upperside of body and forewing grey, the hindwing and dark markings of fore- 



wing and abdomen walnut-brown, underside of body and first segment of palpi greyish white, wings pale 

 walnut-brown with grey base. Forewing above with distinct white discocellular dot lying in the anterior broad 

 portion of the antemedian transverse band, between the lower radial and upper median branches a longitudinal 

 streak, which is connected with that band and distally reaches to an elliptical submarginal spot; between the 

 cell and margin four transverse lines, the first two of which are more or less confluent, the third one slightly 

 developed, the fourth widened anteriorly and here connected with the broad apical oblique stripe. Hindwing 

 with whitish grey markings before the hind margin and at the anal angle. The anal tergite of the cJ divided 

 into two long slender processes, while the sternite is prolonged into a single long slender process ; harpe broaden- 

 ed and rounded at the apex; sheath of duct with pointed apical process which is directed frontad and lies 

 on the sheath. — Shanghai; X^orthern India; rather rare. 



scribae. M. scribae Aust. Smaller than analis, to which scribae is allied in structure, especially of the genitalia; 



thorax anteriorly not darkened; the two brown lateral stripes of the abdomen so broad that the greyish white 

 spots lying between them are smaller than in analis and more or less separated one from the other; underside 

 of body and first palpal segment almost pure white. Forewing above without white discocellular .spot, 

 markings otherwise very like fhose of analis, but blackei, and between the third radial and lower median branches 

 there are two very broad longitudinal streaks wliich are only separated by the first median branch and, as in 

 analis, join distally an elongate submarginal spot; apex marked nearly as in analis; anal angle of both wings 

 less produced than in analis, the outer margin more convex. Hindwing somewhat more blackish than in analis, 

 the grey markings reduced. Underside of both wings brow^nish grey, without the walnut-bi'own tint of analis. 

 As in analis the two processes of the anal tergite of (J long, slender and widely separated in contradistinction 

 to Psilogramma menephron, in which they lie close together, Paronychium with two lobes on each side, Japan 

 and Corea; two (^.^^ in the Tring Muscnun, one $ in coll, Austaut, a second $, from Corea, Alpheraky has 

 figured in Rom. Mem, Lep. IX, plate 13 and placed with Psilogramma menephron increta Walk. 



4. Genus: Psiloj^^raiiiiiia R.d; J. 



Very like the preceding genus, but the second palpal segment has on the inner side a longitudinal 

 bare strijie, which is not present in any other genus. The antennae are shorter and have a proportionately 

 shorter liook. The paronychium consists of only one lobe on each side. The clasper of the o has a patch of 

 modified entire friction-scales on the outer side, and the harpe is only indicated. — Larva dichromatic, a green 

 form with white oblique lateral stripes, and a dark one with broad brown longitudinal stripe dorsally and 

 large brown spots beneath and at the sides; head minutely granulose, thoracical segments each with a trans- 

 verse row of small conical humps; horn roughly granulose, almost straight, slightly upcurved; anal segment 

 also roughly granulose, with brown edges; stigmata dark red. On Anona, Ligustrum, Spathodea, etc. Pupa 

 in the ground, dark red-brown dusted with bluish grey; tongue-case long, free, curved, but not spiral, with 

 the end directed thoracad, — Two species, one of which goes north to Japan in the east of the Palearctic region. 



P. menephron. This species is very variable in the tropical districts of its area of distribution and has 

 received numerous names. It resembles Meganoton scribae, but the discal streaks of the forewing and the 

 increta. apical arcs are thinner. From Japan to Gaylon and eastward to Xew Caledonia ; abundant every^vhere. — increta 

 Walk. (3()b) is pale grey; the markings of the forewing are thin. Japan, Liu-Kiu Islands, Corea and Xorth 

 rtienephron. and East China, Varies comparatively little. — menephron Cr. The specimens from Central and Western 

 China on the whole agree with Indian ones, and like these are very variable in ground-colour and in the thick- 

 ness of the transverse lines and longitudinal streaks. Very light specimens occur which can scarcely be distin- 

 guished from increta, and dark ones which are connected with the light ones by transitions. These tropical forms, 

 which are so different in appearance, will be more fully dealt with in Vol, X.
