Genus Culiciomyia. 235 



$ . The clasper of the male genitalia is curved with a thin 

 lateral wing on the outer side at the curve, and a broader thin 

 wing on the inner side ; at the apical moiety of the outer wing 

 is a tuft of blunt spines, and on the inner, more apically situated, 

 is a single bristle arising from a prominent mamilla ; the apex of 

 the clasper has a blunt tooth at right angles, giving a hook-like 

 appearance, and there are some minute processes between it and 

 the tuft of blunt spines ; the terminal segment is short and very 

 broad, with a median rod and expands apically, and arises on 

 one side near the hook-like extremity of the clasper ; the foliate 

 plate is broad and very concave on one side. 



The male palpi are acuminate, the apical segment nearly 

 three times as long as the penultimate, and with long scanty 

 hairs. The fore ungues are unequal, not nearly equal as 

 mentioned in Yol. II., but not so unequal in size as in the mid

pair. The first sub-marginal cell is much longer and but little 

 narrower than the second posterior cell, its base slightly nearer 

 the base of the wing, its stem a little more than half the length 

 of the cell ; stem of the second posterior cell rather more than 

 two-thirds the length of the cell; posterior cross- vein much 

 longer than the mid, nearly twice its own length distant from it ; 

 scales of normal Culiciomyian form. 



$ . The apical segment of the palpi longer than the rest of 

 the organ, apparently composed of four segments, the basal 

 two small.
