350 HYPOSIDRA: LUXIARIA; AMBLYCHIA. By L. B. Prout. 



behind the median vein of the forewing and a row, or at least a large one distally to the cell, on the hind- 

 wing, particularly noticeable. — Larva rough, the 2nd abdominal segment with a pair of very long, thin, 

 retractile dorsal processes, quite resembling the thorns of the foodplant. Acacia nilotica, 8th abdominal with 

 very small humps; reddish grey with some black spots and bright reddish tubercles. Pupa in a slight cocoon 

 in the crevices of the bark, only a short period passed in this state. Principal emergence in June, but there 

 are perhaps 2 or 3 broods. The resting posture resembles that of the Epiplemids, only the hind wing is not 

 so tightly folded round the body, cj considerably smaller than $, Described from Abyssinia but extends 

 northwards to the Nile Delta (Mansura) and Palestine (Coll. Brit. Mus.). 



paulusi. C. paulusi Rhl. is unknown to me. Antenna of o less closely pectinate, with apex simple, of $ 



dentate, palpus shorter, with small 3rd joint, anal angle of hindwing much less produced, the teeth at 2nd 

 subcostal and 3rd radial stronger, with deeper excision between. 3rd subcostal vein in the $ wanting (perhaps 

 an individual variation). Ochre-yellow, forewing w'th fine, very oblique dark lines at one-third and one- 

 half, the latter sinuous, preceding a row of white somewhat hyaline spots, which is continued on the hind- 

 wing. Palestine: Engedi, December and April. Close to hyperbolica Swinh., in which the $ has the antenna 

 shortly pectinate. 



94. Genus : Myposidra Guen. 



Pace with appressed scales. Palpus rather short, rough-scaled. Tongue short and slender. Antenna 

 in cj bipectinate with long branches. $ abdomen pointed, with long ovipositor. Forewing in cj with fovea'. 

 The sexes generally very different in size and shape and even differing in neuration. ^ smaller, distal margin 

 of forewing comparatively smooth, though often with strongly produced apex, all veins present, 2nd subcostal 

 usually stalked with 1st, occasionally free, occasionally short-stalked with 3rd — 5th. $ much larger, distal mar- 

 gins usually more crenulate, sometimes with a deep excision behind the produced apex of the forewing, 1st — 2nd 

 subcostal comcident. An Indo-Australian and African genus, scarcely represented in the Palearctic Region. 



aquilaria. H. aquilaria Walk. (= kala Sivinh.. albipunctata Warr., davidaria Poatj.) (181). A large, dark, not 



very sharply marked species. The $ has at least twice the vexpanse of the S, the apex more stronglj' 

 falcate. Widely distributed in China; also Sikkim and Shillong. 



Note: falcigere Btlr. (III. Lep. Het. Br. Mus. 2, p. 45), refeiied by Lekch to Hyposidra, is an Oberthiiria and has 

 been described in vol. 2, p. 190 as caeca ab. rutilans Grirnh. 



95. Genus: liiixiaria Walk. 



Pace smooth. Palpus moderate, rough-scaled. Antenna Ln ^ minutely ciliated. Hindtibia in J 

 dilated, with a pencil of hair. Forewing without fovea; apex acute, somewhat produced, 1st — 2nd subcostal 

 coincident, free. Hindwing with distal margin variable in shape; cell sometimes short. This genus also is 

 chiefly Indo-Australian but reaches Japan. 



A. Hindwing with cell extremely short, distal margin strongly crenulate. 



coniigaria. L. cotltigaria Walk. (18 1). Variable, but easily recognized by the structural characters. The name- 



type is yellowish brown in the (5, paler in the $, and has a very wide distribution in the Indo-Malayan Region 

 melanops. and W. China. Hampson enumerates many .synonyms and local forms. — ab. melanops Bastelb. is a frequent 

 amasa. aberration with a large black spot at the posterior end of the postmedian line of the forewing. — amasa Bth. 

 has a warmer brown ground-colour and darker distal area. Japan, Korea and Central China; not, however, 

 everywhere constant. 



B. Hindwing with cell less extremely short, distal margin not cre- 

 nulate (Luxiaria). 



consimilaria. L. consimilaria Leech (18 \ a,s consimilata). Recognizable by the oblique brown bands on the whitish 



ground-colour. Postmedian line marked with black vein-dots. W. China: Mou-pin and Omei-shan. Perhaps & 

 form of the Indian obliquata Moore. 



96. Genus: Amblychia Guen. 



Pace rough-scaled. Palpus moderate, upturned, with dense projecting hair-scales. Antenna in cJ 

 bipectinate. Hindtibia in (J dilated, with strong hair-pencil. Forewing with fovea ; apex minutely falcate; 1st 

 and 2nd subcostals free, Hindwmg with cell .short; distal margin strongly angled at 3rd radial, deeply crenulate 

 from here to the apex. Chiefly Indo-Australian; probably all the forms are referable to one variable species. 



angeronaria. A. angeronaria (%iew. (19 h) may be known at a glance by its shape and its gigantic size. In the name- 



typical form the (J is yellowish almost entirely suffused with reddish and fuscous, the $ much more yellowish, 

 torrida. with conspicuous white apical spot. — ab. torrida Moore is wholly reddish-fuscous in the (?, reddish in the $• 

 — Distributed from India to New Guinea, recently recorded from Japan by Wileman.
