new Genus of Blepharocerid Flies. 209 



2. Elporia capensis, sp. n. 



Early in 1914 I received larvae and pupae of a Blepharo- 

 cerid taken near Stellenbosch, Cape Province, U. S. Afr., at 

 an altitude of about 500 feet. These were obviously distinct 

 from E. barnardi, but, as no adults were received with them, 

 they were put on one side as temporarily indeterminable. 

 Recently, however, I have dissected out two examples of 

 each sex from these pupae, and these specimens are in such 

 an advanced stage of development that it is possible to give 

 a fairly complete description of their structural characters, 

 though, of course, nothing can be said concerning coloration. 

 This, however, is an omission of small importance, and, as 

 the species shows several interesting and rather remarkable 

 differences from E. barnardi, it seems desirable to take this 

 opportunity of describing it. 



Imago : front of the same width in the two sexes, narrower 

 than that of the female, but broader than that of the male of 

 E. barnardi. Eyes in both spxes divided into two portions, 

 of which the upper is a little larger than it is in the female of 

 E. barnardi; in both sexes the facets in this upper portion are 

 slightly smaller than they are in the lower. Pubescence of 

 eyes longer than in E. barnardi, about as long as the width 

 of three facets. Antennae fourteen-jointed in both sexes, the 

 second scapal and the first two or three flagellar joints about 

 half as long again as broad, the first-named being considerably 

 enlarged apically ; the remaining joints more or less globular ; 

 there is no marked sexual difference in the size of the 

 terminal joint, though, if anything, it is a little longer in the 

 male than in the female. Proboscis only about as long as 

 the vertical diameter of the head. Labium of quite a different 

 shape to that of E. barnardi, with no hairs at its tip ; the 

 hypopharynx, on the other hand, has a slightly hairy tip like 

 that of the labrum of E. barnardi. Palpi three-jointed, 

 longer than the proboscis by the length of their last joint ; 

 first joint as long as the last two combined ; last two equal 

 in length ; second joint with a circular pit as in E. barnardi. 

 Labium rather stouter than in E. barnardi, the labella without 

 any " taste-hairs " at the tip, and without a distinct honey- 

 combed structure. 



The genitalia, as in E. barnardi, and as Dr. Lutz informs 

 me is the case in l\etloggina, are not very dissimilar at first 

 sight in the male and female. Their structure is shown in 

 the figures (figs. 13&14). The female has three receptaada 

 seminis. 



The hind tibiae, as in E. barnardi, have a single spur at
