120 DASORGYIA; AROA. By Dr. E. Strand. 



gin brownish yellow with darker irroration as far as the large conspicuous white spot at the inner angle, the 

 wings otherwi.se dark })rown with black spots edged with a lighter colour, and a few small light smears. Hind- 

 wing deep dark chocolate, with two light fringe-lines. J^xpanse 33 mm. The $, which differs greatl}' from the 

 (J, occurs in a form with the wings fully developed and one with thciU half-developed, which are both figured 

 on plate 19 c. The form with the wings fully develo])ed is erroneously marked ,,J", the (J of the .species being 

 figured on plate 22 c. 



6. Genus: 1>asorg;;i'ia Sfgr. 



It is questionable Avhether it belongs to this group; all the species are unknown to me in nature, and 

 not a single fairly reliable description of the genus has as yet been published. It is said to be intermediate 

 between Orgyia and Dasychira. In habitus and markings it most closely resembles Dasychirn, also in the anten- 

 nae, which however have not the pectinations nearly as long as in D. selenitica and the other known species of 

 Dasychira, and in the hairs of the thorax, the shape of legs and abdomen. But the palpi are decidedly 

 shorter tlian in D. fascelina, and the $$ have shortened wings, short serrate antennae and thick woolly abdo- 

 men. Size considerably below the average of Dasychira. Abdomen short, slender, rather acutely pointed, 

 without a conspicuous anal tuft. Known from Central Asia. 



imiiiilfi. D. pumila Stgr. ej: Forewing greyish brown, dusted with black, with an obsolescent central spot and 



t«'o similar transverse lines at one-third and before the outer margin. Hindwing blackish, lighter at the 

 base, with yellowish grey fringes. $ with shortened wings, which are similarly marked as in the (J. ^ 22 to 

 25 mm. Length of body of cj 23 mm. Tarbagatai district. 



seUtwphorei. D. selenophora Sfgr. Wings brownish black. Forewing at the apex of the cell with large sharply 



defined blackish lunulc which has a light edge; the outer half of the cell is dirty white and beyond it there 

 is a light S-shaped transverse line. Towards the base there is also lighter scaling, which sometimes appears 

 as a transverse line. Underside light, with black outer margin. Hindwing with light basal area cbisted with 

 black, in which there is a small central lunule, and broad black outer margin. Expanse 25 or 26 mm. Southern 

 Ferghana. — Grum-Grshimailo figures a form from Pamir under the name pumila of Stgr. which probably is not 

 specifically different from selenophora, but deviates from it in that the forewing bears three distinct whitish grey 

 transverse bands; a small undulating submarginal band, a similar but simply curved one between the first 

 and the middle of the wing and a much broader median band bounding the lunule on the iimer side. The lu- 

 yanihira. nule of the hindwing boiuided externally by a light transverse bar. I call this form var. pamirica mim. luw. 

 (22 b). 



ilphrmhii. D. alpherakii (Jr.-Gr.'ih. (22 b). Forewing yellow with blackish scaling in the marginal, costal and 



basal areas, and l)la(rk discocellular spot. Hindwing with broad black marginal band. Below i>oth wings lighter, 

 the forewing with black discocellular spot. The bipectinate antennae brownish yellow. The body with yellow 

 iinnni. and black hair. Length of wing of , J' 12 mm. Kuku-Nor and Amdo districts. — grumi >S'/^r. has about the same 

 size and colour as selenophora, but the antennae (as in the following foriu) biijoctinate, the branches being 

 twice as long; forewing blackish with two median spots and one beyond the cell yellowish white. Hindwing 

 above uniformly black. The author of the form considers it probable that it is an aberration of alpherakii. 



.<semetwiei. Kuku-Nor (Tibet). — semenowi flr.-Grsh. Certainly closely allied to alpherakii, occurring also in the Amdo- 

 district. Forewing yellow, thickly dusted with black, the centre of the dark-edged median area and the outer 

 half of the cell yellowish white, discocellular spot black. Hindwing yellowish black, darker at the outer mar- 

 gin. On the underside the wings are yellow, densely dusted ^\ith black towards the base. Forewing with the 

 discocellular spot and marginal band black. Body with black hair variegated with yellow in |)Iaces. Length of 

 wing of ,^ 1 3 mm . 



7. Genus : Ai*oa Walk. 



Closely allied to Orgyia, but the palpi much longer and slenderer, the third segTuent porrect, legs 

 less hairy, $ with fully developed wings, pectinations of antennae of the $ shorter than in the .j. Fly in day- 

 time. Usuall}^ small or medium-sized moths of rather uniform yellow or brown appearance. The genus is 

 distributed in South Africa as well as in the Indian Region. 



phimi. A. plana Walk. (22 d). cj 28 to 34 mm., ground-colour mostly light ochreous but sometimes lirownish, 



with a dark but rather obsolescent postmedian band on the forewing. $ ochreous, with dark dusting 

 and a postmedian band on the forewing ; a discocellular spot may be present or absent on both wings.
