HOLOTERPNA; DYSCHLOROPSI.S. By L. B. Prout. 29 



A. fulminaria Led. the name-type of the genus, and the longest-known of the species with the fulminaria. 

 exception of the Indian radiata, inhabits North Persia, Ferghana and a part of Turkestan. It is a handsome 

 species, somewhat larger than its relatives, the strongly zigzag postmedian line very striking. Distal half of 

 hindwing more or less marked with green. 



A. correspondens Alph. (2 g), besides being appreciably smaller, is readily distinguished by its broader comnpon- 

 white markings, the dentition of the postmedian less extreme, by its thicker submarginal interneural wedge- ''^"*- 

 marks and by its mostly white hindwing, which has the second subcostal stalked, whereas in fulminaria it 

 is separate. Local in south-western Siberia, about from Samarkand to Kuldja. 



A. crucigerata Christ. (2g) is of about the same size as correspondens, distal margins somewhat more cntdyeraUi. 

 convex the lines similarly formed but the postmedian less broad; the veins are broadly marked with white 

 in the central as well as in the basal area, the median vein broadly so, thus producing, with the discal spot, 

 the characteristic white cross which has given to the species its name ; terminal wedge-marks nearly as in 

 fulminaria. Palpus (both sexes) considerably shorter than in fulminaria and correspondens. Transcaspia and 

 North Persia. 



A. mabillei Th.-Mieg is also similar. Size of the two preceding, lines nearly as in fulminaria, veins maUUei. 

 white, more as in crucigerata, submarginal wedge-marks of forewing rather short, but connected by a thick 

 white marginal line. Hindwing weakly marked, with an irregular white submarginal and a white marginal 

 line; second subcostal short-stalked, as in correspondens. Central Asia, according to the labels on the type 

 and co-type; the published locality ,,bords de I'Amour", is an error. 



A. radiata Walk, has the antemedian line outangled on the median vein, then oblique basewards radiata. 

 without further bend, the postmedian straight or slightly curved in anterior half, then twice inangled. The 

 hindwing is usually similar to that of correspondens, sometimes, however, the white part is more greenish. 

 Walker's tjrpe was merely recorded as from ,, North Hindostan". The species has since been taken in Kulu, 

 the Scind Valley and at Huang-mu-chang. 



29. Genus: Holoterpna Piing. 



Palpus rather short to moderate. Tongue rudimentary or wanting. Antenna in $ bipectinate, with 

 very short branches. Hindtibia in both sexes with a single pair of spurs. Abdomen robust, not crested. Fore- 

 wing triangular, distal margin very oblique, first subcostal free. Hindwing with inner margin moderately to 

 very long, costal approximated to cell for a moderate distance, second subcostal very shortly stalked. Only 

 two species known, both Asiatic, differing a good deal in shape of hindwing and slightly in several other characters. 



H. diagrapharia Piing. (3 b) is distinguished by its larger size, shorter inner margin of hindwing, diagra- 

 less blue-green forewing, with traces of pale postmedian line, whiter hindwing, etc. In coloration it more ap- ^""'*"- 

 proaches Dyschloropsis. Transcaspia. 



H. pfuinosata Stgr. (2 g) may be recognized immediately by its peculiarly-shaped hindwing and its pruinosata. 

 uniform, pale bluish green colouring, which is only slightly paler beneath. Palestine. 



30. Genus: Dyscliloropsis Warr. 



Closely related to the preceding genus, from which it differs little except in the shorter palpus, longer 

 antennal pectinations, more slender abdomen, less pointed forewing (distal margin less strongly oblique) and 

 differently shaped hindwing, with longer costal margin and with distal margin incurved between first and third 

 radial. Only one species. 



D. impararia Guen. (2 g). Forewing yellow green, with a faintly indicated pale postmedian line. Hind- impararia. 

 wing whitish green (almost white). Underside of both wings uniform pale yellow-green. A scarce and local 

 species first described from the Ural, but since met with in the vicinity of Lake Zaisan, the Ala Tau Mountains 

 and the Uliassutai district.
