204 ^^'' !'• ^^' I'^tlwards on a 



tlicir real structure was discernible. Subsequently I received 

 larvae and pupaj of a second species of South Afric.in 

 Blepharoceridie, and wlion, actiiicr on a sugQ;esti(Mi made to 

 me by ^Ir. 11. Sei^tf. I dissected out ima<;-os from the pupa? 

 of this form and of 7\'. harnard'i, I found that here again the 

 eyes were of the same type, ti)ouu;li there were extremely 

 interesting differences between tiie two forms which will be 

 described below. It thus appears that these South African 

 species torm to some extent a connecting-link l)etween the 

 South American Kellojcjina and the P]urope;in Apistomi/in, 

 resembling the former in wing- venation and the latter in 

 the structure of the eyes. Dr. A. Lutz informs me that he 

 has recently obtained both sexes of a species of true Kellorj- 

 qinn in Brazil, and that in both males and females the eyes 

 are simple. As the condition of the eyes is (doubtless 

 correctly) regarded as a character of geiieric imjiortance in 

 this family of flies, it becomes necessary to form a new genus 

 for A', harnnrdi and the new species referred to. I propose 

 the term Elporia *, which may be defined as follows : — 



Elporia, gen. nov. 



Imago : Eyes dichoptic, hairy, divided by a horizontal 

 band into two distinct parts. Antennae 14- or 15-jointcd. 

 j\Iouth-parts similar in the two sexes; mandibles absent; 

 niaxillre well developed, but without cutting-teeth, as long 

 as the first joint of the ))aljii ; palpi three- or four-jointed, 

 longer than the proboscis by fully the length of the last 

 joint; first joint longer than the others. Proboscis as long 

 as or longer than the vertical diameter of the head. Wing- 

 venation as in PaUostoma, Front and middle tibire without 

 spurs, hind til)ipe with one large spur. Last tarsal joint 

 witliout any group of spines at the base. Claws usually 

 elongate, with several spines on the underside, sometimes 

 partly pulvilliform. 



Pupa: Integument smooth; respiratr>iy horns each com- 

 posed of four flattened lamellae, the two inner much narrower 

 and rather shorter than the two outer. 



Lnrva : Antenna rather short, two-jointed. Integument 

 provided with more or less distinct short spines, the largest 

 of wliich are arranged in a definite way, two occurring near 

 the anterior border, four near the posterior border, and one 

 at each side of each of the five intermediate segments. Six 

 pairs of hairy lateral jirocesses. Five pairs of gill-tufts, each
