POMPILUS NOTATUS. 67 



black. Thorax : the posterior margin of the prothorax suban- 

 gular or nearly rounded ; the metathorax rather longer than 

 in P. exaltatus, the wings as in that species; the posterior 

 femora and tibiae ferruginous, the base of the former black ; the 

 anterior tibiae ferruginous in front ; all the legs have the femora, 

 coxae and tarsi rufo-fuscous, not black. Abdomen : the two 

 basal segments and the base of the third ferruginous ; the apical 

 segments usually with the margins rufo-piceous, the apex fer- 

 ruginous. 



Male. Length 2^-3 lines. The male has the legs coloured like 

 those of the other sex, and the wings are without the milk-white 

 spot at their apex, the third submarginal cell sometimes petio- 

 lated. 



This species very closely resembles the preceding, and might 

 be mistaken for a variety ; but the different form of the margin 

 of the prothorax is, I think, conclusive of its specific distinction. 

 It may probably be the P. obtusiventris of Schiodte and Dahl- 

 bom. It has not occurred near London ; its known localities 

 are Erith, Darenth and Birch Woods, Kent ; it has also been 

 taken at Harrow. 



15. Pompilus (Priocnemis) notatus. 



P. niger ; abdomine basi rufo, alis apicibus fuscis, puncto albo. 

 Mas. Antennis thorace paulo longioribus, abdominis segmento 



secundo supra fascia rubra saepe obsoleta; pedibus partim 



nigris, partim rubris.

Female. Length 4^ lines. Black ; the labrum and mandibles 

 ferruginous ; an impressed line running from the anterior stem- 

 mata to the base of the antennae. Thorax : the posterior mar- 

 gin of the prothorax angulated ; the metathorax very convex 

 behind ; wings subhyaline, with a fuscous cloud occupying the 

 marginal, second and third submarginals, and the upper portion 

 of the third discoidal cells, a milk-white spot beyond, and the
