HESPEKIID^. 



nervures straight. Antennae exactly half the length of the costa of the fore wing, with a 

 •vrell-formed club, the tip slightly hooked ; thorax rather slender, abdomen very slender. 



" Female differs from the male in having the wings broader and more rounded, and lacks in the 

 type species the patch of androconia on the uppersidc of the fore wing.

Aeromachus piceus, sp. nov. (Plate XLI. fig. 16, 6 .) 



Male. Fuliginous : fringes pale greyish, chequered with darker at ends of the nervules. The 

 male has a narrow oblique patch of black raised scales on primaries. Under surface greyish 

 brown : primaries are sprinkled with ochreous along the costal area, and have central and 

 submarginal series of whitish spots, extending from costa to first median nervule ; secondaries 

 are sprinkled with ochreous, and traversed by two series of whitish spots extending from 

 subcostal to submedian veins. 



Expanse 28 millim. 



I have two males which were taken at Moiipin in June. 



Closely allied to A.{T.) stigmata, Moore *, from which it differs in not having 

 a discal series of pale spots on upper surface of primaries and in the macular 

 bands on under surface of secondaries being differently placed. 



Aeromachus catocyaneus.

Agi'ecs in general appearance with A, (T) kaJi, de Niceville, from 8ikkim 

 (Journ. Asiat. Soc. Beng. 1885, p. 123, ii. fig. o, 6 ), but it differs in liaving 

 the bluish macular bands of under surface more clearly defined and gently 

 curved instead of angulatcd. In a carefully executed liand-coloured drawing 

 f)f the male type of A. cntoctjaneus, the primaries appear to liave a transverse 

 dark-coloured patch, l)ut there is no mention of any sucli mark in the 

 description of that insect. Neither is tliis mark rcfernMl to as a character of 

 yl. kali.
