crcnulate, base with a deep round fovea; elytra somewhat convex, only slightly

 form, the shape of the thorax, and its distinctly more conspicuous 

 pubescence.

TWO NEW BRITISH DIPTERA: PEGOMYIA ESURIENS, Mo, 

 AND P. UNIVITTATA, v. Ros. 



BY A. E. J. CARTER. 



When collecting at Comrie, Perthshire, last July, I took a number 

 of ilies belonging to the genus Pegomyia. These when worked out 

 with the aid of Herr P. Stein's recently published paper, " Die uiir 

 bekannten europaischen Pegomyia- A rten " (Wiener Entomologischen 

 Zeitung : Jahr. xxv, s. 47, 1906), yielded interesting results. The 

 genus as it stands in the British list needs revision. Herr Stein 

 making several important changes in nomenclature, besides recording 

 from England some four or five new species. Of these latter I 

 appear to have a ? of P. iniqua, Stein, taken at Musselburgh, June 

 27th, 1907. In Stein's paper it is recorded " ein ? aus England 

 (Grimsbaw)." 



P. esuriens, Mg. The first of the two species now brought 

 forward occurred to me in a woody place in the lower part of Glen 

 Lednock, Comrie, July 8th, 1907, when I captured a well marked £, 

 agreeing with the description given by Herr Stein. The species 

 belongs to the section with black palpi, and a dark, not red or yellow 

 coloured abdomen. Its most striking characteristic is the striped 

 dorsum, unlike anything T have seen in this genus, and reminding 

 one, at a first glance, of a Mydcea, or Hydrophoria conica. The 

 ground colour is dark brown, looked at from behind it is light 

 brownish-grey, with four distinct brown stripes, the two centre ones 

 being narrower and shortened posteriorly. The abdomen is grey, 

 with a fine dorsal line. Legs yellow, with front femora darkened 

 above, and mid and hind femora darkened at the apex. Tarsi black. 

 In my specimen the eyes are separated by a thin line, and the an- 

 tenna? are black, not reddish-grey, at the base. Size, G mm. Stein 

 records it from Genthin (Prussia), Berlin, Vienna, &c, down to Italy.
