the sides of the thorax and all the coxse are covered with 

 a changeahle silvery pile, and the wings are slightly 

 clouded at their margins ; the second submarginal cell is 

 large and oblong, the third becomes gradually about 

 one-third narrower towards the marginal ; the legs 

 nigro-piceous, the anterior pair simple, the intermediate 

 and posterior pairs slightly ciliated ; abdomen narrower 

 than the thorax, smooth and shining, and thinly covered 

 with a silvery pile, the exterior apex piceous."

" Closely resembles P. nic/er, but is a larger insect, its 

 mandibles are entirely black except the extreme apex, 

 which is obscurely rufo-i)iceous ; P. niger has three 

 teeth in the mandibles, one large and two small ones ; 

 the new species has a single tooth, which is only slightly 

 notched inwardly; the 3rd submarginal cell is quadri- 

 lateral and is considerably larger than the 2nd sub- 

 marginal, and the nervures of the wings are much 

 stronger than in P.iiigcr; the latter insect always has 

 the 3rd submarginal either triangular or petiolated ; in 

 the (? that cell appears to be always petiolated. The 

 distinctions enumerated will serve to distinguish the new 

 species."

Differs from Poi)q)ilus in having the vertex distinctly 

 l^unctured in both sexes, and the posterior tibiae serrate 

 externally in the ? . All our British species have the 

 abdomen red at the base, with the exception of the 

 3" of P. Jtt/alinatus. The 3' in the various species is 

 easily distinguished by the form of the ventral anal 

 plate, but the ? is in some cases very difficult to deter- 

 mine with certainty.
