The striatum of the dorsal Burface of the median segment 

 is much liner than in S. lutaria, from which it also differs 

 in the colour of the nervures, tarsi, and first abdominal 

 nent and in the sparser punctures of the mesonotnm. 



The male has the petiole longer than the second joint of 

 the hind tarsus, hut distinctly shorter than the basal joint 

 and the colour of the tarsi is fuscous. 



Sphex (Psammophilet) sheffieldi, sp. n. 



$ . Xigra, nigro-pilosa ; mandibulis basi, segmeutis abdominalibus 

 primo, secundo tertioque basi ruris; clypeo argenteo-pubescente ; 

 alis flavidulis, margiue apicali pallide infuscatis, venis fusco- 

 ferruginois. 



Lung. 22-27 mm. 



$ . Head large and massive, broader than the thorax, 

 densely punctured, clothed with black hairs, the clypeus 

 with a delicate silver pubescence beneath the black hairs. 

 Clypeus broadly truncate at the apex, the apical margin 

 deflexed, the angles of the truncated margin well marked. 

 Inner orbits parallel, the posterior ocelli separated from 

 the eyes by a distance distinctly exceeding the length of the 

 third joint of the flagellum. Thorax and median segment 

 coarsely rngosely punctured, mesonotum with a distinct 

 carina from the base to the middle ; mesopleurse rugose. 

 Anterior coxae not tuberculate at the apex ; joints of the 

 anterior tarsi asymmetrical, but not strongly so ; tarsal 

 ungues without a tooth. Petiole as long as the basal joint 

 of the hind tarsi, the basal third strongly punctured and 

 clothed with black hairs. Radial cell rather long, narrowly 

 rounded at *tlie apex; third cubital cell small, the second 

 transverse cubital nervine nearly twice as long as the 

 cubital margin of the cell and about three times as long as 

 the radial margin.
