A black species with the femora and tibiae red, the orbits nearly entirely 
white and the areola confluent with the petiolar area; costulae sometimes 
obsolete ; stigma infuscate, radix and tegulae pale stramineous; coxae 
and trochanters black, with the anterior of ¢ stramineous. Length, 
6—7F mm: 
Very similar and closely allied to #. flavomarginatus in size, con- 
formation and the length of the intermediate calcaria ; but with the stigma 
darker, the posterior orbits nearly entirely and the frontal throughout 
stramineous, the hind coxae and trochanters deep black or at most 
apically ferrugineous, the areola confluent with petiolar area, the radial 
nervure longer and but slightly curved, the abdomen dilated towards its 
apex with the basal segment longer and the second quadrate, the scape 
pale-marked beneath, the Q face black with a fascia above, a genal mark 
and the mandibles stramineous, the @ with face and mouth entirely 
flavescent. 
It has been found in Germany, Hungary and Sweden in July. Bridg- 
man recorded it as British (Trans. Ent. Soc. 1883, p. 170) on the strength 
of a single female taken at Thornhill; Bignell mentions it from Bickleigh 
in Devon on 30th August; I have recorded the male from Park in Scot- 
land, early in July (E. M. M. 1910, p. 37); Mr. Stanley Edwards took one 
at Lynton, Devon, in 1890; Marshall another at Grovely Wood, near 
Salisbury ; on 8th June, 1904, Mr. Brockton ‘Tomlin sent me a female 
from Cannock Chase; and Rev. W. F. Johnson has found another at 
Mulranny in Co, Mayo.
