and marked with four lines in the female; the abdomen is grey, short and oval, 

 tessellated with brown, and armed with setae botli on the disc and edges of the seg- 

 ments ; the wings are tinged with brown, especially along the fore border, and the 

 apical cross vein is deeply curved. This species closely resembles the Tryphera 

 umbrinervis, Ztt., and I believe that they are only varieties of the same species. 

 Not rare.

This species has the legs entirely yellow, together with the palpi and scutellura ; 

 the facial angle is oblique ; the eyes are widely separated ; the antennae are long, 

 the first and second joints are short and rufous, the third is five or sis times the 

 length of the second, rather narrow, and black or grey ; the thorax and abdomen 

 are both brown, coated with ochreous pubescence ; the former is marked by four 

 black stripes, the latter is tessellated with brown, and armed with setse on the disc 

 and edges of the segments ; the apical cross vein of the wings is nearly straight, 

 and the outer one sinuous. Rare. I received one some years ago from Mr. Bignell, 

 bred from a Lepidopterous larva found in the New Forest ; Mr. Harwood, of Col- 

 chester, also gave me another a few months ago.

The eyes of the male are somewhat approximated ; the fronto-orbital bristles 

 are in two rows, the inner row extending half way down the face, the outer one 

 consisting only of four set£B and not going beyond the base of the antennae ; the palpi 

 are yellow and clubbed ; the antennae are black, with the third joint three to four 

 times the length of the second ; the arista is long and slender, and only thickened 

 at the base ; the thorax is grey, with four black stripes and has white shoulders, the 

 scutellum is yellow; the abdomen is shiny metallic-brown (aeneous), with somewhat 

 narrow, white, transverse bands on the second and third segments, and is armed with 

 rather small setae on the disc and margins of the rings ; the legs have the tibiae 

 testaceous or yellow. Very rare. I found a single male of this well marked species 

 near Maidstone, in Kent, in June, 1888. 



E. LUCORUM, Mgn. 



The palpi, scutellum and tibiae are rufous, also the sides of the first and second 

 abdominal segments in the male. The frontal stripe is wider than the sides of the 

 frontalia ; the palpi are somewhat clavate at the ends ; the antennae have the third 

 joint between two and three times longer than the second ; the arista is long and 

 slender, and only thickened along its basal third ; the thorax is black and hoary, 

 with four rather indistinct longitudinal lines ; the abdomen is without discal setae 

 on the middle segments, and is tessellated with black and grey marks. Eare. 



E. GNATA, Mgn. 

 This species so closely resembles the former that I believe they are only varieties 

 of the same. The frontal stripe is only as wide or even narrower than the sides of 

 the frontalia ; the third joint of the antennae is fully three times as long as the 

 second ; the arista is thickened along half its length, and is less slender than in E. 

 lucorum, and the redness on the sidee of the abdomen extends a little on to the
