A black species, with the vertex angularly emarginate centrally ; 
abdomen centrally and the legs fulvidous-testaceous, with the posterior 
trochanters basally black; @ with hind coxae above and the abdomen, 
except central fasciae, black. Scutellum broadly pale. Length, 3—4 mm. 
This is a small species somewhat resembling #7. pumilus, but at once 
known by the colouration of the Q abdomen, the g hamate mesonotal 
marks, apically broadly pale scutellum and fulvescent hind tibiae. It is 
probably much mixed in collections with the last species, whose scutellar 
colour is dissimilar, and from which it also differs in having the head 
broader than thorax and strongly constricted posteriorly ; vertex short 
and angularly emarginate; ¢ cheeks, pronotum and underside of 
flagellum, also pale; metathorax very finely punctate and not rugose, 
with areae and costae entirely wanting; scutelium broadly at apex or 
nearly entirely flavous ; central segments more or less broadly red; basal 
segment twice longer than broad in 4, postpetiole nearly longer than 
broad in 92, and very finely punctate ; second segment not transverse nor 
basally striolate between the small and subcircular thyridii, its disc im- 
punctate but with sparse impressions and, like all the following segments, 
very finely alutaceous; third and sometimes fourth of ¢@_ basally 
stramineous ; legs slender with hind tarsi infuscate ; of 9 pale red, with 
base of posterior trochanters black and the hind tibiae apically subinfus- 
cate ; of ¢ stramineous, with hind coxae and trochanters black above ; 
stigma narrow and stramineous; nervellus intercepted far below its 
centre. 
Thomson says the areolet is occasionally wanting; that the 9 may 
have (1) the second and third segments fulvous, with humeral mesonotal 
marks and apex of scutellum broadly flavous, and mouth whitish ; or thus, 
with (z) the second segment half black at its base and the scutellum 
bearing a large quadrate mark ; or as in the first but with (3) the third 
segment nearly entirely fulvous. The ¢ varies in having the third and 
fourth segments basally flavous-white or all the femora with a black basal 
mark beneath. 
To note these peculiarities Thomson must have possessed a good 
series ; but otherwise this species was known by one female taken by 
Manger in Silesia and two females captured by Boheman in Sweden. 
Although it was introduced as British by Marshall in 1870, on the 
strength of a single female in his collection from Cornworthy in Devon, I 
have seen no indigenous examples, and the only record was published by 
Bignell (Trans. Devon. Assoc. 1898, p. 501) ‘‘ Captured at Bickleigh, 
4th August and 14th September.”
