Family LYC^l^ID^. 

 4. PITHECOPS BASSARIS, n. sp., PL H, Figs. 4, ^ ; 5, $ . 

 Habitat : Ke Islands. 

 Expanse: $, 1-25; $, 1*40 inches. 



Description : Male. TJpperside, forewing with the base and the 

 outer margin broadly black — the black basal portion extends to about 

 half the length of the discoidal cell, the outer black portion com- 

 mences near the costa a little beyond half its length from the base of 

 the wing, and sweeps round in a regular curve to the anal angle 

 where it is about a millimeter in breadth ; the costa narrowly black ; 

 the rest of the wing pure white. Hindiving black all except a large 

 patch of pure white which occupies the apex of the wing to about the 

 middle (or rather beyond) of the costa and extends on the disc as far 

 as the third median nervule. Underside, forewing with a black 

 costal thread, the outer margin blackish, but less broadly so than on 

 the upperside, bearing a series of five increasing submarginal white 

 lunules, and a marginal series of very fine linear white spots. 

 -ff^/^f/w^«(7 with a very large round intensely black spot on the costa just 

 before its middle, the outer margin broadly black not reaching the 

 apex, decreasing somewhat towards the anal angle, bearing a series 

 of white lunules and another of white spots much as in the forewing, 

 these two series of markings almost coalescing and thus giving the 

 appearance of a series of marginal round black spots incompletely 

 surrounded each by a white line. Female. Differs from the male 

 in being larger and blacker. Forewing with the costa broadly black, 

 the black area reaching as far as the subcostal nervure ; the outer 

 black area much larger, being about three millimeters wide at the 

 anal angle. Hindwing as in the male. Underside, both tvings 

 with the white markings in the outer black marginal area more 

 prominent. Antennce black, the shaft prominently spotted (not 

 annulated) with white below.
