SPHEGID.-E. 139 



C. signatus, Pam. — Very like the preceding, bat the 

 ^ distinguishable at once by the smaller head, the sharp 

 geual spine at the base of the mandibles, the yellow scape 

 of the antennaa, the entirely yellow tibiie and tarsi, the 

 former of which are dilated, smooth, and rounded without 

 spines, and by the small sharp tooth near the base of the 

 posterior femora on their inner margins. 



? very like dimiJiatits, but the vertex has two narrow 

 carinre extending obliquely across the impressions, origin- 

 ating near the anterior margin, and directed inwards towards 

 the posterior ocelli ; the abdomen has the basal segment 

 rather shorter in proportion to its apical width, the apical 

 dorsal valve less strongly and more remotely punctured ; 

 the sixth dorsal segment has ventral spines in the cJ, as 

 in dimidiatus ; tibiiB entirely yellow, posterior pair more 

 rounded externally, and less spinose. 



L. 12 mm.

 Glanvilles Wootton ; {Dale). Colchester, (J and ? ; (Har-

 I have taken a few ? , which I believe belong to this 

 species, near Chobham. 



C. vagabimdus, Panz. — Head and thorax black, hairy, 

 rugosely punctured, somewhat superficially in the cj, scapo 

 of the antennae, except a black line posteriorly, a line across 

 the collar, or two transverse spots, and in the ? a spot on 

 the scutellum, yellow, head impressed in the region of the 

 ocelli, antennte simple, cheeks not spinose ; basal area of 

 propodeum smooth and shining, surrounded and divided 

 down the centre by crenate sulcatures, beyond the basal 

 area somewhat rugose and hairy ; abdomen shining, black, 

 basal segment scarcely longer than its apical width, not 

 petiolated, with a narrow transverse yellow band, generally 

 absent in the cJ, second and third segments in both sexes 

 with wide lateral yellow spots almost united on the disk,
