is dark grey, cyliiidrico-eoiiical, liairy, witli an iiiterruj)lfil dorsal stripe, foruied by 

 three widisli tapering black spots ; the wings are of a brownish-yellow colour, more 

 intense at the base ; Iho hind tibiffi of the males are clothed along their fi'oiit and 

 inner surfaces witli soft liiiirs of moderate length, 'i'he female has the frontal space 

 black, and the abdomen nigrescent and immaculate. Kather local, not uncommon 

 in Yorkshire, and I have received it from Mr. ]Jale, in Dorsetshire. 



II. sETicRUKA, Rond. 



This well-marked species has only been described by Eoudani. It is charac- 

 terized by the arista being rather shortly but thickly haired ; the face slightly 

 prominent ; the eyes of the male contiguous; the proboscis thick, as in ll.Jlavi- 

 pennis ; the thorax yellowish-grey, with five longitudinal stripes ; the abdomen 

 oblong, flattened, very hairy, ash-grey, with a narrow longitudinal sti'ipe ; the sub- 

 anal appendages of the male large, and furnished in front with two projecting hairy 

 lobes ; the wings sub-luteous ; the legs spinous ; and the hind tibiae thickly 

 armed with long rigid hairs, or fine bristles, along the whole of their inner and front 

 sides. The females, which were unknown to Rondani, have the eyes separated by a 

 wide space, having a central red stripe, bordered by a white margin on each side 

 about half the width of the stripe ; the thorax marked as in the male ; the abdomen 

 brownish-grey, conical, hairy, and immaculate ; the wings nearly colourless, strongly 

 ciliated along the front half of the costa, and with a long costal spine (the costa is 

 nearly smooth in the male). The legs are spinous. Grenerally distributed. 



Length of both sexes, about G mm. (3 lin.). 



H. cAKDui, Meig. 



The diagnosis of this species is involved in a good deal of obscurity. It was 

 not known to either Zetterstedt or Rondani ; the former, however, probably con- 

 founded it with his A. brimnesceiis, for the descriptions of the two species correspond 

 pretty closely, and in his last volume he remarks that Dr. Winnertz in 1856 sent 

 him a specimen of A. brunnescens under the name of Ant h. cardui, Meig. 



I have not seen a typical example of H. cardui, but shall give a short account 

 of the British species, which appears to me to correspond most closely to the de- 

 scriptions given by Meigen and Schiner of that insect. 



Eyes of male sub-contiguous ; face sub-prominent, white with brown reflexions ; 

 epistome unprojecting ; arista with short hairs, and having a shining black, short, 

 oval prominence at its base ; thorax brownish-grey, with greyish-white sides, marked 

 with three longitudinal black stripes, one central, straight, diminishing in breadth 

 from before backwards, and two lateral, sinuous and irregular ; the stripes are sepa- 

 rated by two I'ows of bristles, which give the thorax the appearance of being five 

 striped ; addomen long, narrow, depressed, and hairy, with the second segment 

 prolonged, ash-grey with black reflexions, marked with a black interrupted longi- 

 tudinal dorsal stripe, and transverse lines ; the sub-anal process of the male is 

 furnished with two projecting lobes, and there is a tuft of shortish black hairs on 

 the under-surface of the middle abdominal segment ; wings yellowish-brown, the 

 third and fourth longitudinal veins parallel to each other behind the external trans- 

 verse vein ; fore tibite with one bristle projecting from the middle of the external
