 pallide testaceis ; tegulis, j)')'onoti lateribus, costa, stigmate, yedlhusiiae 

 alUdis ; femorihas fere totis, tarsis ijosticis tihiarumque cq)ice nigris ;

Long. 2 lin. 



Female — Head black ; vertex punctured ; the face (including 

 the portion between the antennae) and the orbits of the eyes 

 broadly testaceous, the face being paler, almost white ; antennae 

 black, almost bare, a little shorter than the body. Thorax black, 

 shining, pronotum edged with white ; tegulae white. Abdomen 

 a very little shorter than the head and thorax, black, the apex 

 blunt, sub-trunctated, terebra projecting considerably ; cerci pale. 

 Wings clear hyaline; costa and stigma white; 1st sub-marginal 

 nervure very faint ; 2d almost (if not quite) joined to the 2d 

 recurrent ; 2d sub-marginal cellule large ; 3d small, a little less 

 than a quarter of its length longer than broad ; its apex slightly 

 widened. Legs thickish, white ; the coxae at base, the femora, 

 except at the base and apex, the posterior tarsi and the apex of 

 posterior tibiae, largely black ; anterior tarsi fuscous ; posterior 

 calcaria white. 



The male I do not know. 



The above described species belongs apparently to the AUctiim 

 group. I have carefully compared it with all the descriptions I 

 can find, and with none of them can I make it quadrate, so am 

 obliged to consider it undescribed. It was taken by myself at 

 Eannoch, in June. 



It is very like N. Sharpi, Cameron, but that species has a thicker 

 body ; more sharply pointed abdomen ; feet testaceous rather than 

 white, and quite devoid of black (but from analogy I should think 

 that ^specimens of N. Skarpi will yet be found with the femora 

 marked with black) ; and the antennae are undoubtedly brown 

 underneath. 



Nematus furvescens, sp. n. 



N. nididus, niger, fronte jnmctatula, antennis breviuscuJis, filiform i- 

 bus ; facie inferne, j^ronoto, pedibusque albo testaceis ; femoribus tinea 

 sujyra, vet infra; tarsis posticis tibiarumque apice nigris; alis apice 

 lenissime fumatis ; stigmate testaceo. Sic fern ina. Long. 2-2^ tin. 



Female — Head much narrower than the thorax, shining.
