POMPILUS ACUMINATUS. 



the legs spinose ; the abdomen with the fifth ventral segment 

 slightly emarginate. 



This species is by no means abundant ; it occasionally occurs 

 in the London district ; it has also been taken at Hawley, Hants, 

 and at the Undercliff, Isle of Wight. It provisions its nest with 

 the larvae of Lepidoptera, and has several times been captured 

 with a small green caterpillar.

 Pompilus acuminatus, Smith, Cat. Brit. Hym. 119. 



Male. Length 4 lines. Black ; head very delicately punc- 

 tured, with a few larger punctures intermixed; the clypeus 

 with a thin silvery pile ; the antennae about as long as the 

 thorax, robust, and of uniform thickness, the apical joint acumi- 

 nate. Thorax very delicately punctured, the metathorax more 

 strongly so, and covered with silvery pubescence, which is dense 

 at the sides ; the sides of the thorax and the coxae covered with 

 a changeable pile ; wings hyaline, their apical margins clouded ; 

 the second submarginal cell large and oblong, wider than the 

 third, which is narrowed by one-third towards the marginal ; 

 legs nigro-piceous, the anterior pair simple, the intermediate 

 and posterior pairs with a double row of slight spines. Abdo- 

 men narrower than the thorax, smooth, shining, covered with 

 thin iridescent pile, and compressed posteriorly ; the extreme 

 apex pale testaceous. 



This species was sent to me some years ago from Scotland, 

 since which it has not been captured ; there is a second specimen 

 in the Cabinet at the British Museum, from the collection of 

 the late James Francis Stephens, Esq.
