93 LITHOSIID^E. 



(Bernstein). f. Batchian (type y) (Wallace). g. Mysol (type 8) 

 (Wallace). 



Apparently all one variable species. The example from Mysol has 

 a thin marginal brown band to the hind-wings, and those from 

 Morty and Batchian have no brown streaks in the interspaces on 

 the fore-wings. 



Mr. Butler is in error in saying (Trans. Ent. Soc., Lond., 1875, 

 p. 322) that the type is in the B. M. ; the Aru type and all the types 

 of the varieties are in the Oxford University Museum. 



408. Hypsa ochrealis. n. sp. 



9 Bright ochreous, palpi with a black spot at the base on each 

 side, and another at tip of second joint, last joint and antennae black, 

 thorax with a black spot on each side in front, abdomen with a dorsal 

 row of black spots. Fore- wings with six black spots near the base 

 on each side, three sub-costal and the other three in a curve below. 

 Hind-wings slightly paler towards the costa, otherwise all the wings 

 and body are of one bright uniform dark ochreous colour. 



Underside, slightly paler but perfectly uniform in colour ; fore- 

 wings with a black sub-costal spot beyond the middle, abdomen with 

 small lateral black spots ; legs grey. 



Expanse of wings 2^ inches. 

 a. Goram Ceram (type) (Wallace). 



Belongs to the insularis group. H. instilaris (Boisd.) from 

 Bourbon, has narrower wings than in that species, and differs in the 

 black spots above and below. 



409. Hypsa avacta. n. sp. 



? Bright ochreous, palpi black above, ochreous beneath, last joint 

 and the antennae black, thorax with a black spot on each side in 

 front. Fore-wings with five large black spots near the base, two on 

 the costa and three in a curve below. Hind-wings with the costal 

 portion slightly paler, otherwise both wings and body are of a 

 uniform bright ochreous colour ; all but the first segment of the 

 abdomen of this otherwise perfect specimen is missing, and there- 

 fore it is impossible to say whether the abdomen is banded or not ; 

 the split frenulum however proves its sex. 



Underside, as above, hardly paler, colour perfectly uniform ; both 

 wings with a large black patch on centre of costa, and fore-wings 

 with pale black suffused streaks along the costal space, legs brown 

 above, whitish beneath. 



Expanse of wings 2^, inches. 

 a. Batchian (type) (Wallace). 



Allied to the preceding species, is paler and of a different shade 

 of colour, differs in the colour of the palpi, the black spots at base 

 of fore-wings, and the large black patches on the wings beneath.
