abdomen. The stripes upon the thorax vary very uuich in width ; in pale varieties 

 there are only two narrow central ones extending all the length of the dorsum ; 

 while in some dark specimens there are four broad ones which sometimes cover 

 the whole back ; the scutellum is yellow, sometimes with a central dark stripe ; the 

 apex of the abdomen is tinged with yellow ; the legs are yellow ; the wings have a 

 dark streak on the upper margin, and the cross as well as the long veins are marked 

 with brown. Length, 3 — 4 mm. I have only seen one specimen which I captured 

 near Bradford in 1889. 



Phytomyza nigripennis, Fin. 



This, one of the largest species in the genus, is of a brownish-black colour ; the 

 head is black, face rather oblique ; antennae and palpi black ; halteres white ; 

 abdomen brown with apex glistening black, and a white streak on the edge of tlie 

 pi-evious segment ; wings nigrescent ; legs black. Length, 4 mm. Mr. Beaumont 

 captured this fly at Oxshott in 1894. 



Phytomyza Zetteestedtii, Schiner. 



This is very similar to P.flavoscuteUata, Fin., and may be only a variety of the 

 same. It diifers from it by having the scutellum grey instead of yellow with only a 

 pale mark down the centre ; the femora also are marked with black or grey on their 

 upper surface instead of being quite yellow. Length, 2 mm. A specimen of this fly 

 emerged from soil in which some cauliflower plants injured by the larvae of Phorbia 

 floccosa, Mcq., had been sent to me from Dalkeith. 



OSCINIS PRIT, L. 



This little shining black species has the head, face, palpi, proboscis, and antonufe 

 black ; the arista is bent in the middle and covered with pubescence which in certain 

 lights has a white glimmer ; the halteres are white ; the legs are black with the 

 tarsi yellow all but the last joints of the hind legs. Length, about 1^ mm. A 

 number of these little flies were sent to me some years ago by the Eev. O. 

 Pickard-Cambridge, which he had found in a granary in Dorsetshire in wliich (I 

 think he said) barley had been stored.

ON A VARIETY OP SCOP ARIA DUBITALIS, Hb. (Pl. I). 

 BY HERBERT FORTESCUE FRYER. 



Collecting at Eastbourne in the early part of last summer I was 

 compelled by an almost continuous wind to seek such sheltered spots 

 as could be found. 



One of these sheltered spots deserves perhaps a short description 

 owing to the occurrence there of a pale Scoparia, which I was unable 

 to identify, and which I thought might possibly be a new species.
