rather aliorter and less pointed, tlu' front coxae paler, the front femora 

 not darkened near the base, the front tibite without a row of black 

 spines down the inside, the abdomen thinner and blacker, the genitalia 

 less retracted ; the third and fourth joints of the hind tarsi bear some 

 very short erect bristles beneath, about five on each joint, but bear no 

 long hairs ; the alulae are pale haired. The female is smaller than that 

 of S. annulipes, and is easily known by its yellow front coxae and fe- 

 mora, black hind tibiae, pale-haired alulae, and narrower face. It is 

 the Dolicliopus nigritihialis of Zetterstedt's Dipt. Skan. xii, p. 4638. 

 Only one male has been recorded from (Eland. I caught two pairs on 

 Scotsdon Moor, near Aberdeen, on the ISth July, ISTl, and one pair 

 at Braemar three days later. 



8. BIFASCIELLUS, Zett. 



This species seems to occur over north-west Europe, in single 

 examples. I caught one male at Upware on July 10th, last year. It 

 is a very small species, the third joint of the antennae being long, 

 pointed, and pubescent, the face is narrow, silvery, the frons shining 

 blue, silvery about the edges ; the thorax shining green ; the legs and 

 coxae all pale yellow, except the end of the tarsi, the basal joint of the 

 hind tarsi shorter than the second ; third and fourth joints not bristly 

 nor hairy. The abdomen is blackish, a yellow band occupying most of 

 the first and second segments, the genitalia are rather protruded. The 

 discoidal vein ends in the tip of the wing. 



Campsicitemus loripes, Hal. (not Fall., as in my list). 



An almost black-legged variety of this occurs at Aberlady.

lIvDUOiMioKis PKJX'ux, Jjchui., Gcrst. (= II. incequalipes, Lw.). 



This species, although omitted from my list and from Walker's 

 Insecta Britannica, is perhaps one of the commonest British species. 

 It has the wings unspotted, the face and frons all glossy white, the 

 abdomen white haired, greenish-grey, the front femora with spines of 

 equal length, reaching to the tip, and the front tibiae with about four- 

 teen moderately long spines on the inside, of which the last is longer
