498 EHOPALOCERA. 



brand in the male is narrow, in some species not easily seen till the larger scales are 

 removed. 



The antennse are considerably less than half the length of the costa, and have a 

 stout club, terminating in a short crook. The palpi have the third joint short, stout, 

 and bluntly conical. The primaries are strongly produced at the apex ; the cell is much 

 less than two-thirds the length of the costa and produced at the apex ; the upper 

 discocellular is very oblique, and fully twice the length of the lower ; the lower radial 

 is depressed at its base : the first branch arises from a little before the middle of the 

 median nervure, the second from close to the lower angle of the cell. The secondaries 

 are slightly lobed at the anal angle ; the cell is short and broad ; the discocellulars 

 are transverse and very faint, except at their origin. The body is robust. The middle 

 and hind tibise are spined, the latter with two pairs of spurs. The primaries of the 

 male have a very narrow, indistinct, sinuous, oblique, interrupted brand, extending from 

 the base of the second median segment to the submedian nervure, this being more 

 apparent in A. Marina than in A. deva or A. pittacus. 



We have dissected the genitalia of the males of three of the species and find them 

 very similar.
