shorter and thinner; the colour black above, beneath brown, 

 except with the three basal joints, which are entirely black. 

 Head, black, shining ; the vertex, faintly punctured ; the clypeus, 

 labrum, and palpi, brown; the mandibles, black. Thorax, black 

 above and beneath, shining; the pronotum, edged laterally with 

 testaceous ; tegulae, testaceous ; cenchri, obscure white. The 

 head and thorax are covered sparingly with down. Abdomen, 

 black, the ventral surface testaceous ; the apex is somewhat 

 acuminate, pilose, cerci very short ; terebra, slightly projecting, 

 hairy. Feet, testaceous; coxae and trochanters paler, the former 

 black at the extreme base ; posterior tarsi and tibiae, at the apex 

 black, or rather fuscous ; anterior tarsi, faintly marked with 

 fuscous ; posterior tibiae, slightly channelled on the inner side. 

 Wings, iridescent, faintly smoky (as in Nematus quercus); costa 

 and stigma, fuscous, the latter paler at the base ; the third sub- 

 marginal cellule almost square ; the first submarginal nervure 

 very distinct; the second submarginal is united to the second 

 recurrent. 



This species belongs to the Ahietum group. I can find no 

 description in the works of St Fargeau, Stephens, Hartig, Foerster, 

 and Thomson, with which it will quadrate. The alar cell structure, 

 unicolorous femora, and somewhat pointed abdomen, will serve to 

 distinguish it. Taken in Scotland ; the exact locality I have not 

 noted, but I do not think that it was taken in the Glasgow 

 districts.
