postscutellum and a minute spot below the anterior wings pale yellow; 
a spot on each side of the second, third and fourth abdominal segments 
yellowish white ; tegulae and legs, except the coxæ and trochanters, 
light ferruginous ; a spot on each side of the vertex ferruginous red. 
Wings hyaline, iridescent ; nervures fuscous. 
Length 5—6 mm. 
5 . Clypeus sparsely punctured, very short, truncate at the apex, 
slightly convex in the middle but without a carina. Head shining with 
a few scattered punctures, the punctures smaller and closer above the 
base of the antennæ, a short longitudinal sulcus between the antennæ, 
the head subrectangular, half as broad again as long, rounded at the 
posterior angles, much broader than the thorax. Thorax shining and 
almost smooth, with a few fine punctures on the median segment, the 
pronotum much broader anteriorly than long, narrowed posteriorly, 
broadly longitudinally elevated in the middle, the sides depressed, with 
the lateral margins raised. Median segment a little shorter than the 
pronotum, broadened from the base and obliquely truncate posteriorly. 
Abdomen as long as the head, thorax and median segment combined, 
shining ; the first, third and fourth segments broadly depressed at the 
apex, the raised portion before the apex strongly bilobed and sparsely 
punctured, the second segment with three strong transverse carinæ in¬ 
cluding the recurved apical margin ; the pygidium deflexed, long and 
very narrow, the ventral segment extending a little beyond the dorsal, 
rather wider and rounded at the apex. Fifth ventral segment sparsely 
punctured, finely aciculate at the base. 
Entirely testaceons. 
Length 4 mm.

This little species is related to the last (exiguus), but the shape 
of the hypopygium, the slenderer antennæ and the difference of colour 
distinguish it amply. 
The male in the Hungarian National Museum has the second 
cubital cell rather longer than the third on the radial nervure, the 
second recurrent nervure is received by the third cubital cell just be¬ 
fore one third from the base. The male from Woodford has the third 
cubital cell distinctly longer than the second on the radial nervure 
and the second recurrent nervure is received by the third cubital cell 
a little beyond one third from the base.
