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

 first known Suuth-AtVican Blepliarocerid under the name 

 Kellogj/ina harnardi. More recently (iSepteniber 1915) I 

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

 same time a second South-African species, E. cap>-iisis. I 

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

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

 has recently .sent me larvae and pupse, which were collected by 

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

 3000 feet on the Caledon side of the Hottentots Hollands 

 Mountains. Several of the pupse were sufficiently advanc(d 

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

 is from the.^e specimens that the adult characters have been 

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

 any reference to coloration. The new species is much more 

 nearly allied to E. barnardi than to E. caj ensi"-^ but the male 

 claws resemble those of the last-named, and the larvse 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 

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

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

 lar<^er than it is in E. capensis, but, as in E. harnardi, it is 

 composed of larger facets than tho.ie 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. Antennae 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; tiiere are no strong hair.«, except one 

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

 short dens<! ))ubescence. Mouth-p irts agreeing closely with 

 those of E. harnardi in structuie, 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 jjalpal
