We have allowed several very divergent forms to remain imder 

 this subfamily head for the time being, largely because of insuf- 

 ficient material in this exceedingly interesting group. Deino- 

 cerites cancer Theo. possesses many features in common 

 with Culex proper, and diverges widely from the abnormal A e d e s 

 f u s c u s O. S. associated therewith. There is little in common 

 between the latter and Uranotaenia. The unique W y e o m y i a 

 s m i t h i i Coq. is an even more divergent type presenting more 

 fifeneralized features. 



^ DEINOCERITES 



This genus is an abberrant, synthetic Culicid, unique not only 

 on account of antennal characters but also in the genitalic struc- 

 tures of both, male and female. The antennae of the female are 

 remarkable in having the second segment greatly prolonged, equal 

 in length to the three following and clothed with scales. The male 

 antennae are greatly produced, the second to the seventh segment 

 being prolonged, the 'Second about the length of the two following 

 and the others gradually decreasing in length to the eighth. The 

 second, third and the basal portion of the fourth segment are 

 sparsely clothed with scales. This entire organ in the male is 

 longer than the body. It is not plumose as in most Culicids, 

 though the hairs covering segments 2 to 7, like those on segment 

 2 of the female, are a little longer and there is little evidence of the 

 sparse basal whorl of longer setae so characteristic of most Culicids 

 and evident in this species on the other antennal segments [Fig. i]. 

 The palpi are composed of four segments in each sex, with the fifth 

 probably represented by a minute apical prolongation. The fourth 

 segment in the male is about one half longer than the third and 

 somewhat larger in the female. These two segments are nearly 

 equal in length though the fourth is somewhat more dilated. 



Deinocerites cancer Theo. Genitalia, male. Basal clasp seg- 

 ment stout, broadly rotmded apically. Terminal clasp segment 

 stout, slightly curved, excavated internally, somewhat enlarged 

 apically, externally clothed with numerous short hairs and bearing 

 in an apical notch a pair of curved, clawlike spines. Claspette 

 represented by a sub apical internal lobe bearing two stout, chit- 

 inous, curved', fingerlike processes, a large chitinous spine and 

 several smaller ones. Harpes short, broad, stout, basal processes 

 crowned with a series of close-set, blunt, chitinous teeth and bear- 

 ing a number of rather stout, subapical setae. Minor limb nearly 

 independent, a very long, stout, chitinous process about two thirds 

 the length of the basal clasp segment, with the basal portion some- 

 Yv^hat enlarged. Harpagones with a long, curved, blunt apical 

 spine, the basal portion broadly expanded, somewhat convolute, 

 with its rounded margin crowned with a series of stout, slightly
