Family ARCTIAD^—contmued. 



Snb-family LITHOSIANiE— continued. 



Genus ChiOn^ma, Herr Schaff. 



1281a. C. alborosea^ Wlk. 



Sikhim, 1,800 feet; Bhutan, 2,500 feet. Females of this are very 



common, attracted to light. I have twenty of this sex, but only two 



males. I have two aberrant females, one of which has all the red 



markino-s replaced by yellow ones and the other which has veins 4 and 



5 of the forewing arising from the cell. I do uot think that C, jy'^dla, 

 Drury, extends as far East as this, though it is a very common insect in 

 the N.-W. Himalayas. 



C, obliquilineata^ Hmpsn. 

 Sikhim, 1,800 feet. This species has a large, erectile tuft on the costa 

 of the forewing on the upperside from the ante-medial line to two-thirds 

 of the costal length and a very large oval, brownish, unilobate fold on 

 the underside. The apex of the forewing is quadrate, the costa dis- 

 torted, and the submarginal pink band bent inwards along the costa. 

 The ante- and post-medial bands are outwardly oblique. Veins 2, 3, 4, 



6 and 7 of the forewiag are curved upwards, and veins 3, 4, and 6, 7 

 of the hiudwing are stalked. I took four males in July and August at 

 Punkabaree, but the female is as yet unknown. 



1284. C. effracta, Wlk. 

 Sikhim, 1,800 — 4,000 feet. I have three males and three females 

 taken at light in June, August and September. 



C. aditaj Moore. 

 Sikhim and Bhutan, 6,400 feet up. This species appears in Sikhim 

 collections as C. signa, Wlk. It, however, differs from that species in 

 having the two disooidal spots on the forewing of the male separate
