pubescence in front, and a little silvery-white pubescence 

 at sides; scutelium similarly coloured. Abdomen brown- 

 ish-black, with dense, long, silvery-white pubescence on 

 sides of the first and second segments ; sides of remaining 

 segments and apex with long black hairs; dorsum with 

 short wdiite and yellow pubescence, the former forming a 

 white band on the second segment. Legs black, compara- 

 tively stout. Wings hyaline, brightly glistening, the 

 base and foremargin a deep blackish-brown. 



Female resembles the male very closely, but the eyes 

 are more widely separated. 



This species resembles A. simplex somewhat closely, but 

 may be distinguished by the long pubescence on sides of 

 the first and second abdominal segments being bright sil- 

 very-white, instead of yellowish-white, by the larger size, 

 and by the more glistening wings with darker foremargin. 



A. arge.ntipennis occurs not uncommonly in elevated bush 

 at Mangalore, during the months of December and Janu- 

 ary. It frequents clr}^ watercourses and similar situations.

 {Spogostijlum, Willist. Cnguilletia, Willist.) 



Antennse with a clearly differentiated style, which is 

 terminated by a pencil of hairs. 



Head broader than the thorax. Proboscis short, not in 

 the least projecting. Eyes narrowly separated in male, 

 more widely in female. AntenuEe very small, the third 

 joint jnore or less onion-shape, with a style-like prolonga- 

 tion, ending in a differentiated style with an apical pencil 

 of hairs. Thorax bearing dense pubesceence; scutelium 

 vrithout any marginal bristles. Abdomen flattened, 

 broadening posteriorly, with a pointed apex, the whole 

 bearing dense pubescenece, which is longest at the sides. 

 Legs of medium length, slender, tibiae with rather long, 

 weak bristles. Wings with the typical venation of the 

 Anthracince ; number of submarginal cells two ; first pos- 

 terior cell wide open ; anal cell either narrowly open, or 

 closed on the wing-margin. 



Tliis genus is represented in Tasmania by a single 

 species, which is easily recognised by its velvet-black abdo- 

 men, with silvery-white apex, and almost black wings.
