that of Dr. Capron from the neighbourhood of Shere in Surrey ; Marshall 
took a female at Nunton in Wilts; and I captured a female in a Lynd- 
hurst garden on 12th July, 1907, in the New Forest.

Head with the clypeus, mouth and whole of the parallel-sided face 
whitish; mandibles small and short, frons entirely black. Antennae 
slender, filiform, subincrassate apically and a little longer than half body. 
Thorax black, with notauli short but distinct and a flavous mark below 
radices; metathorax very strongly convex and very coarsely rugose with 
no distinct costae. Abdomen ovate or subtriangular, broadly petiolate 
and shining; fourth segment apically and anus thence entirely fulvous ; 
basal segment gradually dilated apically, twice longer than broad, with 
spiracles a little beyond centre ; postpetiole aciculate, parallel-sided and 
discally bicarinate ; second smooth, nitidulous and basally deeply foveate ; 
terebra black and shortly exserted. Legs normal, pale fulvous and 
basally stramineous, with hind coxae sometimes basally infuscate ; hind 
tibiae stout and basally constricted. Wings hyaline, stigma stramineous, 
radix and tegulae white ; areolet entirely wanting; nervellus intercepted 
below centre. Length, 3 mm. 
This species agrees with A. padlrdipes, Gr., in its sparsely punctulate 
mesonotum, deeply impressed punctures on segments three to five and in 
the entirely rufescent anus, but differs in its entirely black frontal orbits, 
etc. ; at first Thomson thought the areolet present, but later he agreed 
with Marshall (in MS.) that it was entirely wanting. 
It has been recorded from Silesia, Prussia and Sweden. Bridgman first 
mentioned it in Britain, with no note of its novelty (Trans. Norf. Soc. 
1894, p. 627), from Earlham in Norfolk ; and there are two in Marshall’s 
collection from Bugbrooke in Northants and Bishops Teignton in Devon, 
but in both these the metanotum is strongly nitidulous, hardly punctate 
with but apical indications of petiolar area, and not as described above 
by ‘Taschenberg from the type, which may have been dirty.
