The species of this genus can usually be easily separated from 

 those of Pteronus by the duller and more strongly punctured meso- 

 notum and pleuras ; the shorter and stouter antennsD (seldom much 

 longer than the abdomen and usually entirely black) ; the more trian- 

 gular look of the face with its long tongue ; tlie long sticfma with its 

 rounded base and pointed apex ; and, in the ? ? , by the generally 

 much longer and stouter saw-shcath. In colour they resemble the 

 darker species of Pteronus^ being generally in great part black above 

 and more or less pale at the sides and beneath. Their usual ground- 

 colours are dull reds, browns, yellows, &c. ; and these, as in Pteronus, 

 sometimes result from the fading of hues which were green in the 

 living insects. 



I have examined certainly British specimens (mostly from Scot- 

 land) of nine species, all of which have been verified as to their 

 identity by Herr Konow. 



Cameron's Monograph enumerates seven, but of these Konow 

 considers histrio and glenelgensis to be identical, and placidus a 

 Lygcdonematus. Arcficus, C. (nee Thomson ?), is also probably not a 

 member of the present genus ; at any rate it can hardly be Thomson's 

 species, which is placed by the author in a section with " antennae 

 breves, dimidio corpore baud longiores," while in arcticus, C, the 

 antennae are said to be " nearly as long as the body." In vol. ii of 

 the Monograph arcticus is grouped with rumicis,?^. Pachynematus -, and 

 Konow has always considered it to be identical with that species. 



Amauronematus was revised by Konow in Term. Fiiz., 1895, and 

 my tabulation following is chiefly founded on that paper, supplemented 

 by later notes of the same author on particular species, and by my 

 own examination, of specimens named by him. One of our species 

 (woWm, Knw.) does not appear in the Revision, having been first 

 described in 1902. (See Ent. Mo. Mag., March, 1905, p. 63).
