Some time ago (June 1912) I described in tliis periodical the 

 first known South-African Blepharocerid under the name 

 Kelloggina harnardi. More recently (September 1915) I 

 erected for this species the new genus Elporia, adding at the 

 same time a second South-African species, E. capensis. I 

 now describe a tliird, also from South Africa, of which my 

 friend Mr. K. H. Barnard, of the South African Museum, 

 has recently sent me larvse and pupse, which were collected by 

 him in January of the present year at a heiglit of about 

 3000 feet on the Caledon side of the Hottentots Hollands 

 Mountains. Several of the pupaj were sufficiently advanced 

 in development to enable me to dissect out the adults, and it 

 is from these specimens that the adult characters have been 

 drawn. As in the case of E. capensis, this fact precludes 

 any reference to coloration. The wQVf species is much more 

 nearly allied to E. barnardi than to E. capensU; but the male 

 claws resemble those of the last-named, and the larvae are 

 quite distinct from those of either of the two known species. 



Elporia spinulosa, sp. n. 



Imago. — Front considerably broader in the female than in 

 the male, being just one-third the width of the head in the 

 former and one-fourth in the latter sex. Eyes of the male 

 divided into two portions ; the upper part is a very little 

 larger than it is in E. capensis, but, as in E. harnardi, it is 

 composed of larger facets than those of the lower part. The 

 female eyes closely resemble those of E. harnardi, the upper 

 portion being very small and its facets very much smaller 

 than those of the lower. Pubescence of eyes about as long as 

 the width of two facets. Antennge 15-jointed in both sexes, 

 the joints somewhat oval, sessile, and all about equal in 

 length, except the fourth, which is shorter ; last joint slightly 

 enlarged in both sexes ; there are no strong hairs, except one 

 on the first joint, but the whole flagelium is covered with a 

 short dense pubescence! Mouth-parts agreeing closely with 

 those of E. harnardi in structure, but rather shorter, being 

 very little longer than the vertical diameter of the head ; the 

 blade of the maxilla is a little longer than the first palpal
