separate spots. — ab. (?) mactans Btlr. has the ground-colour rather uniform reddish, the hyahne spots want- mactans. 

 ing on the forewing, reduced or wanting on the hindwing, distal area still more strongly grey clouded. 

 Japan: Yokohama and Chusendji. 



G. albipunctatus Hmps. differs in having ths wings strongly suffused with purple-grey excepting aihiptmc- 

 the part of the forewing which lies between the subcostal and median veins and their continuations ; charac- talus. 



teristic is a white dot or small spot near the apex ; the hindwing has an irregular band of somewhat hyaline 

 dots or small spots from middle of discocellulars to inner margin beyond middle. Dharmsala. 



G. apicata Moore. Distal margins not crenulate; apex of forewing strongly produced, especially in apimln.. 

 the $. Duller in colour, sometimes olivaceous, postmedian hne of forewing double or triple, its outer consti- 

 tuent running to the apex, its continuation on hindwing ending in some irregular, thick dark markings, 

 proxima.Ily to which stands a variable row of hyaline spots. N. India, including Dharmsala. Also on Formosa. 



G. ' argillacea Bth-. (25 b). Shape of apicata. much moce simply marked, both wings with discal dot an/iVacea. 

 and dark chestnut, proximaUy pale-edged, oblique line, forewing also with indistinct antemedian. Dharmsala; 

 W. China. 



G. signata Btlr. (16 b). This species (the type of Btjtlees genus Epifidonia) and the two which follow sigtiatn. 

 are perhaps on an average broader winged than the preceding group, the abdomen rather slender, the hind- 

 wing withoat hyaline spots, the underside rather bright orange-yellow, signata is char? cterized by a white 

 spot on the forewing, placed as in the quite differently coloured albipunctatus but much larger. Some examples 

 are much more heavily dusted with fuscous than others. N. W. Himalayas. 



G. lateritiaria Pouj. (= laterinata Pouj.). Palpus elongata. Costal margin of forewing more arched, icderiiirma. 

 distal margin of both wings smoother. No white spot on forewing. The wings concolorous, with two slender 

 lines from apex of forewing to middle of inner margin of hindwing, separated only by a whitish thread. 

 Under surface with a dark postmedian line, a dark spot in middle of distal margin and another in middle of 

 hindmargin of forewing. W. China: Mou-pin and Huang-mu-chang. 



G. virilis sp. nov. (16 b). Eye rather small; palpus long, with 3rd joint elongate; forewing with \s,t mrlHs. 

 subcostal anastomosing at a point with costal. In shape nearest lateritiaria, colours as in specularis. Lines 

 rather thick, antemedian far from base, the basal areas heavily strigulated with fuscous; distal area characteristic, 

 entirely suffused except a patch between hindmargin and 1st median. Underside similar to upper, with less 

 red irroration. Omei-shan, W. China, 2 ^^, 13 — 15 August in my coUeetion. 



42. Genus: Apericallia Leech. 



More slenderly built than Phalaena, wings narrower, more smoothly scaled, forewing slightly concave 

 from apex to 3rd radial, here pointed, otherwise smooth. Palpus rather long and strong. Antenna in 5 simpl^ 

 Pectus not densely hairy. Femora glabious. Hindtibia in ^ slender. Neuration of Phalaena. Erected for the 

 single species here given. 



A. bilinearia Leech (16 c). Very pale violaceous (almost whitish), dusted with olive-brown, hindwing hiUnenrin. 

 paler. The lines of the forewing are almost straight and parallel, reproduced beneath; that of the hindwing 

 is fine and indistinct beneath, but accompanied proximaUy by a shadowy band of ochreous. W. China: Pu- 

 tsu-fang and Ta-chien-lu ; May — July. 



43. Genus : Heterocallia Leech. 



Habitus of the preceding, agreeing in most structural characters. Antenna in ^ simply ciliated. Hind- 

 tibia in (^ strongly thickened. Forewing with 1st subcostal stalked with 2nd and anastomosing with costal. 

 Also founded on a single species. 



H. truncaria Leech (16 c). Very distinct in the strongly curved postmedian line, blackest in the middle, tnmcaria. 

 where it is followed by a longitudinal dark brown mark behind the 3rd radial; and in the pure white spots which 

 mark the anterior part of the subterminal line. W. China and Formosa. 



44. Genus: licptoiuiza Wan-. 



Perhaps not a very natural or sharply defined genus. Hampson differentiates it from Phalaena by 

 the more oblique distal margin of the forewing and the simple $ antenna. From Garaeus it is distinguished 

 by the naked eye. Antenna in the (^ variable; also the wing-shape, though the distal margins are always 

 crenulate. The genus is chiefly Indian.
