A broad-headed, black species, with immaculate antennae and red legs. 

 Head not narrowed posteriorly, of S with fine brown pubescence ; clypeus 

 of $ slightly bisinuate, of <$ rounded ; cheeks and temples inflated ; palpi 

 fuscous, mandibles and apices of cheeks red ; frontal orbits in ^ , a line at 

 the internal and external and a dot at vertical orbits of <?, whitish. An- 

 tennae very slightly attenuate towards apex, sub-filiform, 

 entirely black in both sexes ; seventh flagellar joint 

 quadrate. Thorax, with scutellum, entirely black, stout ; 

 or, in c?, sometimes with pronotum and dots at radix 

 and two at base of scutellum whitish, mesonotum some- 

 what shining ; areola of c? short, transverse and smooth, 

 ^'^^c^.tnpns^or!'^^ of ? somcwhat elongate, with costae weak and emar- 

 ginate apically ; costulae entire. Abdomen dull black, 

 with a slight violet reflection and incisures rarely rufescent ; post-petiole 

 aciculate-punctate, with lateral areae simply punctate ; second segment 

 quadrate, not or hardly longer than broad ; gastrocaeli large and deep, 

 intervening space rugosely striate. Legs stout, black ; all the femora and 

 tibiae, as well as anterior and the base of hind tarsi, red ; hind coxae nearly 

 glabrous, scopulae castaneous, large and elevated. Wings hyaline ; stigma 

 and tegulae piceous ; areolet broad above. Length, 12-15 mm. 



This species is distinguished by the fulvous tibiae and femora, and the 

 black $ antennae ; while the tibiae and femora of the 3 are red, the abdo- 

 men less strongly sculptured and the clypeus truncately rotund. 



/. 7iigricortiis, Wesm., diff'ers in nothing but its larger size, being 15-18 

 mm. long {cf. Kriech. Ent. Nachr. 1896, p. 354). 



In the British Museum is a specimen said to be of this species with no 

 areolet in the right primary. Irregular neuration is very rare in the Ichneu- 

 moninae, and had both wings of this example been thus curiously abnormal, 

 it would probably have long remained an unique species or even genus. 



It has been bred at Lynn, in Norfolk, on June i ith ; in Devon ; and, upon 

 other occasions, from Goriytia flavago ; and has been found at Guestling, 

 in Sussex, Essex and Hartlebury, in August ; near Birmingham, and at 

 Ogley Bog, Oxford, in July. It is probably common, but its distribution 

 appears nearly confined to our own latitude in Europe.
