 (PI. 1, fig. 300 ; Text-figs. 21-24) 



Thymistida nigritincta Warren, 1923 : 474. [Published simultaneously with rufa ; here 



selected as the valid name for this taxon.]

 Thymistida rufa Warren ; 1923 : 475. syn. n. 

 Hybodrepana grotesca Bryk, 1943 : 23. syn. n. 



This species can be distinguished from tripunctata Walker (q.v.) by the shorter 

 antennal pectinations in the male (longest pectination equal to about three quarters 

 greatest width of eye), the distinctively shaped costa of the fore wing, and by the 

 male and female genitalia. 



Distribution. N.E. India and N. Burma.

Thymistida nigritincta divisa Bryk, 1943 : 2}>- syn. n. 



This species is readily separated from the similarly marked nigritincta by the 

 much larger antennal pectinations in the male (longest pectination equal to over 

 twice greatest width of eye), the less sinuous costa of the fore wing, and by the male 

 and female genitalia. 



Distribution. N.E. India, N. Burma and China (2 $, from Siao-Lou, Szechwan, 

 in the BM(NH)). 



Types, tripunctata. Holotype <$, labelled ' E. India '. In the BM(NH). The 

 locality is given as ' Hindustan ' in the original description. The abdomen of the 

 holotype is missing. 



cervinaria. The syntypes stated to be from Bengal are lost according to Horn 

 and Kahle (1937 : 380), but there is a short series in BM(NH) from the Moore Coll. 

 labelled cervinaria.
