 with a stramineous callosity before the radix, notauli wanting; metathorax 

 distinctly and not very closely punctate with all the areae distinct, areola 

 elongate and emitting distinct costulae from its centre ; petiolar area verj- 

 short and distinctly carinate basally ; pleurae punctate and nitidulous. 

 Abdomen shining with the oblique impressions deep ; second and third 

 segments subquadrate and apically obscurely rufescent ; the fifth and 

 following nitidulous ; carinae of the basal segment nearly reaching its 

 apex, which is obtusely angled ; terebra a little shorter than the abdomen. 

 Legs fulvous, hind ones red ; anterior coxae and trochanters of $ flavous ; 

 bases of the apically infuscate hind tibiae and tarsal joints white ; fifth 

 hind tarsal joint not longer than the fourth. Wings with the stigma testa-

[The following description of G. nigrina, drawn from Desvignes' Cata- 

 logue and amplified by an examination of the co-types in the British 

 Museum, lea\es very little doubt respecting the above synonymy : — 



Head constricted behind the eyes, black with the mouth ferrugineous 

 and the palpi fulvous ; clypeus with only short pubescence, not discreted 

 but on the same plane as the face which has the epistoma prominent. 

 Antennae somewhat longer than half the body, ferrugineous above flaves- 

 cent with the scape sometimes apically flavous beneath. Thorax black 

 with an often elongate flavescent callosity before the radix ; metathorax 

 convex with all the areae very plainly delineated ; areola elongate, hexa- 

 gonal, emitting distinct costulae from its centre ; petiolar area distinctly 

 costate basally and centrally, .short and subvertical. Abdomen black, 

 somewhat nitidulous and as broad as the metathorax ; basal segment a 

 little longer than broad, with the carinae extending but little beyond its 

 centre; the following segments subquadrate; terebra slightly shorter than 

 the abdomen. Legs pale red ; front, and sometimes the intermediate 

 coxae, flavescent ; hind femora infuscate at base and apex, their tibiae 

 dark, basally whitish ; tarsi infuscate. Wings with the stigma piceous or 

 dull .stramineous, radix and tegulae flavous ; nervellus intercepted slightly 

 below the centre. Length, 8 mm.] 



Desvigne« described this species from three males (and another mis- 

 placed), from Stephens' collection, in the British Museum. Bridgman 

 says (Trans. Norf. Soc. v. p. 72) that Atmore bred both sexes from Auli- 

 thesia capraeana dLwd Paidisca so/andriana at Kings Lynn in 1889. It is 

 probably widely distributed, though not ver}^ common in Britain. I pos- 

 sess three males: one taken by Piifard at Felden, in Herts, on 24th June, 

 1900 ; one bred from an unascertained host by Clutten, at Burnley on 8th 

 August of the same year ; and one taken on a window of Monks' Soham
