Female. Length 4 Hues. — Black ; the head closely and finely 

 punctured, the apex of the mandibles ferruginous ; the clypeus 

 and cheeks with a few scattered pale hairs. Thorax finely 

 punctured ; the posterior margin of the prothorax arcuate ; the 

 metathorax gibbous, transversely rugose and subopake; the 

 anterior wings with a narrow transverse dark fascia occupying 

 the transverso-medial and the geniculation of the interno-medial 

 nervures, beyond which is a much broader fascia crossing the 

 wing at the marginal and submarginal cells, which it occupies ; 

 the apical margin of the wing with a narrow dark border en- 

 closing a milk-white spot ; the anterior tarsi with a few short 

 cilia, the intermediate and posterior tibiae with a double row of 

 very short slight spines on the exterior. Abdomen shining and 

 delicately punctured; the two apical segments with scattered 

 long rigid hairs, most dense at the apex. 



Male. Length 3 lines. — Black; the head closely and finely 

 punctured, the front very convex, the antennae as long as the 

 thorax. Thorax punctured ; the metathorax covered with short 

 silvery pubescence, strongly and closely punctured, with a shal- 

 low longitudinal impressed line extending from the hase to the 

 apex ; the wings subhyaline and iridescent, an indistinct fascia 

 crossing the anterior wings at the marginal cell, beyond which 

 a milky spot is faintly perceptible ; the anterior legs, with the 

 knees, apex of the tibiae, and first joint of the tarsi, pale rufo- 

 testaceous ; all the calcaria pale testaceous. Abdomen lanceo- 

 late, smooth, shining and very delicately punctured ; the apical 

 margin of the basal segment slightly depressed ; the fifth ven- 

 tral segment slightly emarginate ; the sixth with two deeply 

 impressed lines, each terminating in a deep emargination at the 

 apical margin. 



This species is rare in the south of England, but is not un- 

 common in the north ; it has been taken several times, however, 

 at Coombe Wood, where, in 1837, I captured two females; in 

 July 1852, I took ten females and one male, near Wakefield, 

 Yorkshire. This insect prefers wood-sides, where it burrows in 

 banks of light earth. The male described was taken in company 

 with the other sex, and has not been previously found in this 

 country ; it is exceedingly active, and difficult to capture.
