towards the sides becoming more dense;- the wings hyaline and 

 iridescent, the nervures and stigma pale rafo -testaceous. Abdomen 

 subovate, shining and delicately punctured, thinly sprinkled with 

 pale pubescence ; a similar pubescence clothes the legs and thorax.

This is a very common species, found in all parts of the United 

 Kingdom ; it has been received from Scotland, Wales, and Ireland.

Female. Length 3-3 lines. — Black ; the nagellum of the antennae 

 fulvo-piceous beneath towards the apex; the head and thorax 

 finely and very closely punctured. Thorax, the wings hyaline and 

 iridescent, the nervures pale testaceous; the tegulae rufo-piceous ; 

 the metathorax truncate ; above with a radiating striation, acutely 

 margined laterally ; the pubescence sparse and cinereous, that on 

 the legs short, dense, and slightly yellowish. Abdomen ovate and 

 shining, impunctate, beyond the basal segment with a thin short 

 cinereous pubescence ; the apical margins of the second, third, and 

 fourth segments with very thin pubescent fasciae, which are usually 

 subobsolete. B.M. 



Male. — Black ; the nagellum of the antennae pale fulvous beneath ; 

 the anterior tibiae and tarsi reddish yellow, and the base of the 

 intermediate and posterior tibiae yellowish as well as the tarsi. 



This species appears to be restricted to the north of England and 

 to Scotland. I discovered it in 1842, at Woolley Edge in Yorkshire, 

 about four miles from Wakefield ; since that time it has been received 

 from Scotland; the specimens were identified by Dr. JSTylander. The 

 species is found in Sweden, Einland, and Lapland. Dr. Nylander 

 suggests that Kirby's H. fulvicornis may prove to be the male ; but 

 that insect is the male of H. Icevigatus. 



Div. II. The body more or less metallic.
