hexagonal and hardly broader than long. Abdomen not shorter than 
thorax and red with the first segment entirely, second basally and a cen- 
tral fascia, nigrescent; basal segment somewhat convex, with carinae 
extending nearly to its apex. Legs stout and black with only the tibiae, 
which are not paler basally, tarsi and apices of femora rufescent. Wings 
somewhat broad and a little clouded; stigma and tegulae ferrugineous, 
radix pale; areolet wanting; nervellus intercepted below its centre. 
Length,4—5 mm. 6 only. 
The @ differs solely in having the third and fourth segments infuscate 
basally, with the terebra black and not exserted. 
This species was placed by Bridgman in the present genus and recorded 
by him (Trans. Ent. Soc. 1886, p. 364) as taken on 11th June, 1885, at 
Dulwich in south London; elsewhere it is only known from Russia. I 
have a single pair; the male was captured by Albert Piffard at Felden 
near Boxmoor in Hertfordshire, and I swept the female from rank 
herbage on 27th August, 1905, in Tuddenham Fen, Suffolk. Stenton 
took one at Wimbledon, early in August, rgro.
