214 On a new Genus of Blepharocerid Flies. 



the tip. The proportions of the tarsal joints are much the 

 same as in E. barnardi, except that the first and fifth joints 

 are relatively a little longer; the first joint is as long- as the 

 next three taken together ; the second, third, and fourth 

 gradually decrease in length, while the fifth is as long as the 

 third and fourth combined. The male claws are swollen 

 towards the base, with a thin curved tip ; the basal portion 

 is densely hairy, almost pulvilliform, but there are no spines 

 on the underside. The female claws, on the other hand, 

 rather closely resemble the male claws of E. barnardi in 

 shape and in possessing several sharp spines on the underside. 

 The male claws are very interesting, as exhibiting some 

 approach to the abnormal pulvilliform claws of the male 

 HapaloihrisB lugubris. 



The wing-venation is apparently the same as in E. barnardi, 

 although it is very difficult to make out in detail, owing to the 

 crumpled condition of the wings. 



Pupa of a somewhat different shape from that of E. bar- 

 nardi ; the portion in front of the respiratory horns descends 

 less steeply (at an angle of about 45° instead of about 60°). 

 The respiratory horns closely resemble those of E. barnardi. 



Larva in all essential features resembling that of E. bar- 

 nardi, but much more spiny, the largest and most conspicuous 

 spines occurring on the lateral " pseudopodia." As in the 

 case of E. barnardi, the young larvae have three, the full- 

 grown ones five, gill-filaments in each tuft. There is a small, 

 slightly spiny, lateral projection on the anal segment, which 

 in K. barnardi is hardly present, being represented by the 

 merest knob ; from this projection or knob arise in both 

 species two long hairs, springing from a common base; these 

 hairs are rather longer and more conspicuous in E. barnardi 

 than in the new species. The spiracles are present, as in 

 E. barnardi, and have a more complicated structure. The 

 two pairs of anal papillae are very unequal in size and the 

 anal armature differs from that of E. barnardi. The tip of 

 the antennae bears two small appendages, one of which is 

 two-jointed. 



Summary and Conclusions. 



1. It has been found necessary to found a new genus, 

 Elporia, for Kelloggina barnardi on account of the divided 

 eyes. This genus differs from most Blepharoceridse in that 

 the females, like the males, have no mandibles. 



2. A new species of this genus is described, differing 

 markedly from E. barnardi in all its stages.
