by that author, and as a good species by Kriechbaumer ; the cheeks are 

 more strongly dilated, the antennae basally ferrugineous, and the fourth 

 and fifth segments are not margined with white. 



This is a common species in Britain ; Gravenhorst tells us it occurs in 

 August and September, and that Hope took both sexes about Netley ; 

 Stephens records it not uncommonly about London and in Salop, in July. 

 It is common in Norfolk and Essex; Professor J. W. Carr has sent me 

 specimens to name, from Arnold, near Nottingham, and Mr. Beaumont 

 has found it at Stretton, both in the middle of August ; Mr. Wainwright, 

 in Wyre Forest, in the middle of September; Mr. Hamm, at Streathy; Mr. 

 Chitty, both sexes at Huntingfield, in August ; Mr. Sladen, at Ripple, near 

 Dover, also in September, and Mr. Piffard, at Felden, in Herts. I have 

 only met with the female during hibernation, in tufts of Aira caespitosa, 

 at the Bentley Woods, near Ipswich, in April. It is common on the 

 Continent, where it has been bred from Goriyiia flavago ; Mr. Adkin has 

 also bred the female in Britain, from Odones/is Rotatoria, Linn.

A handsome, elongate species. Head black, temples somewhat buccate; 

 oral costa not elevated ; mandibles bidentate, short and slender, those of 

 $ as well as the apically truncate clypeus in its centre, and usually too 

 the middle or sides of its face, flavous. Antennae somewhat slender, 

 setaceous, black ; of ? white-banded with the basal flagellar joints filiform, 

 of which the sixth is quadrate ; of <^ with scape white beneath. Thorax 

 black with a white line before the radix ; areola semi-elliptic, a little longer 

 than broad ; costulae and apophyses obsolete. Scutellum white. Ab- 

 domen black, of $ sub-cylindrical ; the second and usually the third 

 segments entirely red, the remainder apically white-marked ; post-petiole 

 aciculate ; gastrocaeli obsolete ; third segment of $ quadrate ; fourth 

 ventral not plicate ; hypopygium of $ always short, laterally sinuate but 

 not apically acuminate. Legs normal, black ; tibiae and tarsi, except 

 apices of the posterior, and whole of ? front femora, red. Wings flaves- 

 cent with stigma fulvous ; $ with tegulae usually white-marked. Length, 

 12-16 mm. 



I have, in spite of Thomson's protestation, provisionally retained 

 Wesmael's name for this species as being that in general use, but it 

 would appear probable that that of Linnaeus, whose description I have 

 not seen, will eventually have to be adopted. 



This is not an uncommon species on the Continent, where it is widely 

 distributed ; Holmgren found the female beneath the bark on a dead tree, 

 and the males referred to, collecting socially in autumn beneath oak bark, 

 by Gravenhorst were almost certainly females too. It has been bred from 

 Leucania vilellina, Gorlyna flavago, and Cucullia Santonici. In Britain, 

 as far as I am aware, it is recorded only from Devonshire, where this
