or very little enlarged posteriorly, minutely striolate, rufous, 
ruf escent, or nearly black ; 2nd ruf escent at the base. Terebra 
exserted, much shorter than the abdomen. $ Similar ; antennae 
17-jointed in my specimen. Length, | ; wings, 1|- lines. 
Yar. Rufo-castaneous, with the head and tip of the abdomen 
blackish. Haliday. 
At present I refer to fuscicornis, all specimens of 
minute size having the base of the abdomen rufous, and 
few joints in the antennas. Nevertheless, doubtful in- 
dividuals occur, and the species is far from being well 
established. Common in England, Ireland, and Scot- 
land.

$ . Black, shining ; mandibles rufous ; palpi obscure ; clypeus 
very short, black, separated from the face by a deep furrow ; face 
prominent, convex, smooth. Antennae shorter than the body, 
stout, slightly thickened in the middle, 18-1 9- jointed. Meso- 
thoracic sutures effaced ; dorsal fovea punctif orm ; metathorax 
dull, punctate-rugulose, sometimes with two small shining areas 
close to the base. Wings hyaline ; squamula pale brownish ; 
nervures distinct, fuscous, arranged as in the preceding species ; 
1st cubital areolet always separated from the 2nd, and from the 
1st discoidal. Legs rufous ; hind coxae sometimes partially obscure, 
as well as the femora and tibiae of the same pair. Abdomen and 
terebra as m fuscicornis. ^ Similar ; antennae wholly black, longer 
than the body, 22-24-iointed ; legs rufescent with the base of 
the hind coxae obscure, femora more or less fuscous, often with a 
fuscous streak above ; tibiae and tarsi fuscous at the apex. Length, 
; wings, 2|— 3| lines. 
The limits of size given by Haliday sufficiently indicate 
that his description includes more than one species. 
But as some definite type must be selected, if a descrip- 
tion is to have any meaning, I have chosen that which I 
believe to be the commonest. The specimens which 
furnished the above description were all homogeneous.
