subcostal, the middle one the largest and following the median, while 

 the shorter one runs along the internal nervure. This region is bounded 

 externally by a pale ashen line which begins on the basal third of the 

 costa and runs obliquely inwards. It is twice zigzag before the sub- 

 costal, is bent more obtusely outward in the discal space, and again 

 bends slowly outwards, and turns at a right angle to meet the dark 

 streak on the internal nervule; hence it does not entirely cross 

 the wing. The discal mark is a faint curvilinear line, succeeded be- 

 low by a rather oblique very obscure cinereous lunated line. Upon 

 the costa just beyond is a white spot, once zigzag on the costa, edged 

 without with black. Beyond this spot are three minute dark dots, 

 the inner of which is succeeded by a series of four large pale lunules 

 margined on either side with cinereous, which end on the 3d median 

 being in the od interspace replaced by a square conspicuous black spot, 

 whose upper side is continued a little outwards, while on the opposite 

 lower side is a supplementary linear dot in the next interspace. This 

 spot is continuous with a submarginal oblique subapical zigzag pale 

 line, dusky within, and bearing within three dark streaks in the mid- 

 dle of each interspace. Beyond this line the margin is dusky cinere- 

 ous, with a marginal series of black linear lunates, interrupted by the 

 nervules. Fringe dark cinereous. 



Hind wings but little paler than the abdomen, with a rather distinct 

 pale submarginal band. Base of fringe dark as are the nervules and 

 outer margin of the wings. The only mark on them is a single oblique 

 costal streak a little beyond the middle of the wing. 



This species is rather above the medium size, and will be known by 

 the pale ashen bleached primaries, the basal third of which is very dark 

 cinereous. Also by the linear obscure discal line, succeeded on the 

 costa by a white zigzag spot, and more especially by the square black 

 spot near the internal angle which is isolated from the submargino-api- 

 cal dusky line, of which it forms a part.

Lochmaeus olivata. 



% . Olive green cinereous, being greener at the base of the fore wings 

 and more ashen externally. Head and thorax concolorous with the 

 base of the primaries, but the palpi are much darker. Antenuje nearly
