rounded posteriorly, third emarginate, its einargination 

 fringed with long hairs, fourth and fifth entire, armature 

 with the stipites long and subparallel, convergent at the 

 apex so as partly to enclose the sagittse, ? with the scopa 

 black ; legs clothed with very pale brownish hairs, in the 

 (J, with grey in the ? , calcaria black, posterior metatarsi 

 beneath, without a spine or tubercle. 



L. 7-10 mm. 



Common and generally distributed, occurring from May 

 to August. It generally burrows in old posts, &c., but 

 occasionally in hard banks, or old walls. In my Synopsis 

 Trans. Ent. Soc, 1884, p. 208, I see now, for the first time, 

 that I represented the propodeal area of this species as being 

 " dull," how I could have made this mistake I cannot 

 imagine, as its shining area is the character by which it is 

 known from several of its Continental allies.

 ingly like that of the preceding species, but rather larger, 

 thorax more obscurely metallic, and duller, the puncturation 

 being closer, wings rather more smoky, especially in the 

 marginal cell ; abdomen slightly longer, the sixth segment 

 distinctly emarginate, armature with the stipites less 

 parallel, gradually narrowed to the apices which are less 

 convergent, and do not in any way enclose the sagittae ; 

 posterior metatarsi with a spine beneath, this is not very 

 easy to see, as it projects in the middle of the dense 

 bristly hairs which clothe the underside of the joint. 



? , head and thorax dull, closely punctured, greenish black, 

 sparingly clothed with greyish fulvous hairs, wings smoky 

 brown, propodeal area shining, abdomen shining, largely, 

 and not very closely punctured, except on the fourth and fifth 

 segments, black with bluish or greenish reflections, almost 

 glabrous above, the sides fringed with orange yellow hairs, 

 sixth segment clothed with adpressed greyish hairs, 

 beneath with the scopa bright orange, legs clothed with 

 pale hairs, calcaria black. 



L. 9-10 mm.
