NISONIADES.— CYCLOSiEMIA. 375 



The single species of this form we find in Central America (which we describe below 

 as K pelarge) is strictly congeneric with " N. bromius, Stoll," according to Mr. Watson ; 

 and wherever that insect is placed hereafter, W. pelarge must go with it. 



The antennae have a moderate club, gradually curved to a point. The palpi have 

 a short porrect terminal joint. The primaries have no costal fold; the inner margin 

 is longer than the outer margin, these wings being thus rather narrow; the cell 

 is moderately long and rather narrow, the first median segment short, the third 

 less than half the second ; the lower discocellular is longer than the middle, the 

 upper short but evident ; the second and third subcostal segments are subequal ; the 

 third median segment of the secondaries is short, the lower discocellular longer than 

 the upper, the radial being distinct. The hind tibiae have a distinct dorsal fringe, but 

 no tufts.

N. bromius (apud Watson) is perhaps the species most nearly allied to that now 

 described, but the latter may readily be distinguished by the glaucous colour of the 

 inner third of the secondaries, the costa of which alone is dusky. 



We have several specimens of both sexes from Belt's collection, but no others from 

 an authentic source. 



The tegumen of the male genitalia is short and blunt and cleft at the end; the 

 scaphium is well developed, curved upwards, and projecting as far as the end of the 

 tegumen ; the harpes are deeply cleft at the end, the lower portion wide and expanding 

 at the outer margin, the upper portion nearly uniform in width, slightly turned upwards 

 and rounded at the end (see Tab. LXXXIV. fig. 3). These organs are exactly like 

 those of N. bromius.

Cycloscemia is very closely allied to Mr. Watson's Nisoniades, and perhaps not really 

 separable. The primaries are rather wider and the third median segment shorter, the 

 secondaries more rounded ; the terminal joint of the palpi rather longer. There also
