1912.] S7 



Col. Yerbury again found it in large numbers at Bridgend and 

 at Port Talbot in Glamorganshire, on July 29th, 1908, on the black 

 mud of the estuary up to August 11th, sitting on pebbles in the middle 

 of the river. 



40. Gymnopternus breviconiis, Staeg. : A male was taken by 

 Col. Yerbury at Nethy Bridge on June 19th, 1905. It is very closely 

 allied to G. ater, but has dark lamellte to the male hypopygium. 



41. G. angustifrons, Staeg.: I introduced this little species as 

 British in 1875 upon the strength of a specimen so named by Loew ; 

 subsequent examination of the specimen convinced me (as I stated in 

 1881) that it was only a small female G. cvpreus. I am now however 

 convinced that a male taken by Dr. J. H. Wood at Moccas Pool on 

 September 24th, 1910, belongs to true G. angmtlfrom, and I have 

 compared it with Continental specimens named by Kowarz. 



42. Chrysottcs svuvis, Lw. : Col. Yerbury again took C. palustris 

 at Porthcawl in 1906, and at Port Talbot, Pyle, and Bridgend in 

 August, 1908, l)ut he also took two males of the closely allied C. suavis 

 at Porthcawl on June 11th, 1906, one male at Bridgend on July 29th, 

 1908, and a pair on August 16th. C. suavis has the face narrower 

 than in G. palustris, the anterior tibiae paler, and the minute bristly 

 hairs on the abdomen pale. 



43. C. melampodius, Lw. : While dealing with this genus I may 

 as well record this and the following species as being probably British. 

 The distinctive chai-acters are very difficult to follow, but I believe 

 I have several specimens of C. melampodius from Brockenhurst, 

 Dolgelly, Hever, Porthcawl, &c. 



44. C. varians, Kow. : The distinctive characters between 

 C. gramineus, angulicornis, microcerus, and varians as given by 

 Kowarz are very difficult to follow, but I have so much faith in 

 Kowarz's critical eye that I believe they must be distinct species. At 

 one time I doubted his new species of Medeterus allied to M. trun- 

 corum, btit I am now convinced that Kowarz was right. Under these 

 circumstances I may say that I think I have taken C. varia7is at such 

 widely divergent localities as Lyndhurst, Piu-ley, Stokenchurch, and 

 Eannoch. 



45. Argyra grata, Lw. : Dr. J. H. Wood took a male of this 

 well-marked species at Pentebro', in Herefordshire, on August 3rd, 

 1909, and he also took three females at Moccas on August 10th. 

 A. confinis and A. atriceps appear to be fairly common in Herefordshire.
