A. plenaria Leech (7g). Rather narrower winged, with distal margin of hindwing very slightly (scarcely ple?iaria. 

 noticeably) bent in the middle. Distinguished further by its more brownish white ground-colour and the 

 numerous very regular waved lines. Chang Yang. 



A. defectata Chr. (= chrysidia Btlr.) (10 h). Straw yellow, easily distinguished from the rather defectata. 

 similarly coloured plurilinearia by the rounded distal margin of hindwing, less acute apex of forewing, reduction 

 of the dark markings, absence of subterminal pale spots, angular projection of postmedian line of forewing at 

 P' radial, etc. Antenna in cf almost simple, minutely ciliated. Ussuri district, Korea and Japan. 



A, straminearia Leech is very near defectata (10 h), the palpus rather less strong, the ground-colour rather stramine- 

 paler yellow, all the markings weaker, the antemedian line forming a regular curve, while in defectata it is "''*"■ 

 angulated before the middle, no trace of the longitudinal dark cloud in the middle of the distal area which 

 is discernible (often strong) in defectata. Founded on a single worn cf from Wa-shan, W. China. Perhaps 

 merely a form of the preceding, which seems generally more weakly marked on the continent than in Japan. 



A. distinctaria Leech (7g) differs from defectata in having the wings white, with only a tinge oi disHnctaria. 

 yellowish, the costal margin of the forewing broadly ochreous; the median line is more strongly angled at 

 the P' radial. Palpus short. W. China: Wa-shan and Pu-tsu-fong. 



A. plurilinearia Moore (= unistirpis Btlr) (10 i). & antenna minutely ciliated, not dentate. Hindwing pluri- 



subcrenulate, between the radials weakly emarginate. The markings, as shown in our figure, are unmistakable, ""^^'''^s- 



— ab. denigrata Warr. lacks all the black shading of the distal area. Distributed from N. India to Amur- denigrata. 

 land and Japan. 



A. conditaria Leech (7 g) differs from plurilinearia in its darker, less yellowish forewing, with more conditaria. 

 prononced dark median band, and in the paler, often almost white hindwing, which is rarely so strongly 

 marked as in the specimen we have figured and which is unfortunately a little exaggerated in printing. Distal 

 area of forewing without black shading except an oblique apical streak. Ta-chien-lu, W. China, apparently 

 not rare in May — June. 



A. electaria Leech (7 g) is a beautiful and unmistakable species, though agreeing with the two preceding electaria. 

 in shape and structure. The under surface is similarly marked, but duller, the faint median lines of both 

 wings wanting, but the hindwing with a sharply marked, fine postmedian line. The unique example (a ?) 

 is from Mou-pin. 



70. Genus: Cambogia Guen. 



Related to Hydrelia, the areole small or altogether wanting, the 5 subcostals long-stalked, c/' antenna 

 usually with very long pectinations, in some subgenera ciliated. Hindwing with distal margin variable, almost 

 regularly rounded to dentate or strongly angled, 1 =' median usually stalked. 



An extensive genus, most prevalent in South America, but also well represented in the Indo-Austrialian 

 Region and with a few stragglers in the Palearctic. 



A. Antenna in cf with fascicles of long cilia; distal margin of hindwing dentate 

 (Acolutha Warr.). 



C. pictaria Moore (13 m). White. Forewing suffused with grey and reddish in anterior half and with pictaria. 

 yellow in posterior, traversed by 5 thick, waved, interrupted reddish lines. Variable, sometimes more strongly 

 yellow. Distributed in India. Palearctic specimens, except one from Gensan, Korea, July, are unknown to me. 



C. pulchella Hmps. (13m) has the costal area of the forewing much brighter red, more uniform; a strong, pulchella. 

 dark, double submarginal line, often thickened into a blackish spot close to hindmargin; hindwing mostly 

 purplish grey, traversed by thick, irregular darker and pale lines. Hindwing beneath white, with large, well- 

 defined fuscous blotch, narrow at costal margin but rapidly broadening so that at the inner margin it reaches 

 from before the middle almost to the anal angle. Widely distributed in the mountains of India, one specimen 

 recorded by Leech as probably from Yokohama (ex coll. Pryer). 



B. Antenna in cf bipectinate. Hindwing not dentate {Cambogia). 



C. phoenicosoma Swinh. An aberrant species in that the P' median vein of the hindwing arises well phoeni- 

 separate; forewing without areole. Pale yellowish grey, forewing with V-shaped reddish basal patch (its apex '^'^^°'"^"-
