A CATALOGUE OF THE EETEROCERA OF SIKHIM. 549 



1194. D, flavens, Moore. 



Sikhim and Bhutan, 1,800 — 3,000 feet. A common insect at Punkabaree 

 in June, September, and October. Taken with Mcenas venosa in numbers 

 attracted to light, especially in September. The male, which appears to (be 

 undescribed, has the markings arranged almost exactly as in Hampson's 

 figure of D. indica, Guer, {Moths of India, Vol. II, p. 12.). It may bo 

 described as follows :— Deep ochreous ; palpi at sides and antennse black- 

 ish ; abdomen darker ochreous with dorsal, lateral and sub-lateral series of 

 black spots. Forewing with an elongate fuscous spot on the costa ; a 

 aurved ante-medial series of elongate fuscous spots between the veins, 

 sometimes running into a straighter medial series, which latter is excurved 

 round the end of the cell ; a triangular spot in the upper angle of the cell, 

 one just outside the discocellulars, and sometimes a small one in the lower 

 angle of the cell ; post-medial series of elongate spots terminating at the 

 apex in two round spots. Hind wing with a discoidal spot, and generally 

 a complete sub-terminal series of elongate fuscous spots, sometimes obsolete 

 at the middle or reduced to round spots. In the female the spots beyond 

 the medial series on the forewing are generally wanting or represented by 

 one or two elongate spots between veins 4, 5, and 6. One specimen in my 

 collection has five large spots of the post-medial series present. The 

 hindwing of the female has the sub-terminal series reduced from one 

 to four usually conjoined spots towards the tornus with a speck above 

 vein 5 ; one specimen has in addition a post-medial row of 5 conjoined 

 spots towards the inner margin. A black streak is also generally present 

 from near the base of the wing, running parallel to the inner margin to 

 half the extent of the latter. (Judging from the figure in Moths of India, 

 Vol. II., p. 12, 1 should say that D. indica was the male of D. flavens. 

 I have only 3 females of the latter from MoUer's- collection, which agree 

 very fairly with the figure of B. indica. — H. J. E.) 

 1171. D. flavalis,'Mo.ove. 



Sikhim and Bhutan, 5,000 feet. I have two forms of an insect iden- 

 tified by Sir George Hampson as Thyrgorina flavalis, Moore, one of 

 which is typical lativitta, Moore, and the other a pale^unmarked form with 

 the forewings buff and the hindwings white. It seems very distinct from 

 the other, but there are doubtless intermediate forms. It occurs at light in 

 June, August and October. (This was common at Darjeeling in July 

 and August, 1886. I have 12 males, which show every variation from 

 spotless forewings to the well marked band of lativitta. Of my 2 females
