1 02 ENNOMID^. — AMPHIDASYID^. 



ABACISCUS, ffcn. nov. 



Aspect of Hypochroma ; of similar form and markings ; hut structurally nearest to 

 Angerona, there being no radial to the secondaries ; the antennse finely ciliated, not pecti- 

 nated as in Angerona ; the palpi broader ; the tibia3 of the posterior legs almost twice the 

 length of those of Angerona, more uniformly thickened and flattened ; the tarsi shorter : 

 neuration of primaries very similar, but the costal and subcostal veins of secondaries are 

 distorted so that they are contiguous for about a quarter of their length from the base. 



Abaciscus tristis. (Plate CXXXV. fig. 18.) 



Primaries smoky blackish, crossed at basal fourth by a zigzag black line and at centre of

 dots, and terminating on inner margin in a mottled patch of white ; a transverse black disco- 

 cellular litiira ; a submarginal scries of white spots ; a patch of wliite scales, bounded inter-

 spotted with white : secondaries white mottled with blackish, apical border blackish, traversed 

 by three white crescents ; anal border less distinctly blackish, also enclosing three white

 and slightly arched ; the outer one strongly arched ; an oblique black discocellular dash 

 between the two lines; fringe spotted with black: thorax dark smoky grey, with whitish 

 hands across the end of the tegulse ; abdomen brownish, with two dorsal series of black spots

 Ijorders paler, with iiTcgularly dentatcd internal white edges ; the central belt much wider on 

 the primaries, and bordered by considerably thicker and blacker lines : the outer line of the 

 secondaries also thicker, blacker, less angulated, and nearer to outer margin : the thorax 

 decidedly blacker ; the antenniE shorter and much less red in colouring. Expanse of wings
