27, pi. ii., f. 38 (abdomen). 

 Black, shining ; thinly pubescent with short whitish hairs ; 

 mandibles rufous except at the base ; palpi and legs rufo-testaceous, 

 hind coxae black above, fuscous beneath ; hind tibias and tarsi 

 blackish, the former testaceous at the base. Antennas 5 as long 

 as the body, with 30 cylindrical joints diminishing in length 

 towards the extremity ; 2d joint usually dull testaceous: antennae 

 ^ one-fourth longer, 32-jointed. Face punctate, dull, with a deep 

 fovea on each side above the clypeus, and a shallow central de- 

 pression ; clypeus transverse, rounded in front, punctate ; under 

 each eye is a short, shallow groove ; cheeks emarginate close to 

 the base of the mandibles, forming on each side a dentiform 

 process flattened against the surface and not easily seen. Pro- 

 notum rugulose. Mesothoracic sutures strongly incised, punctate. 

 Scutellum small ; ante-scutellar fovea large, punctate, bisected by 

 a carina. Metathorax as in the last species. Wings slightly in- 

 fumated, stigma and nervures fuscous, squamulae testaceous. 

 Abdomen as long and as broad as the thorax, flattened above, 

 shining, with parallel sides, truncated at the end of the 3d seg- 

 ment, beneath which, in the ? , the remaining segments are con- 

 cealed ; in the $ they project slightly. First segment rather 

 longer than its apical width, which is about 3 times that of the 

 base, rugulose ; tubercles obtusely prominent ; two lateral carinse 

 extend from the base nearly to the middle ; 2d segment marked 

 with shallow pimctures, often very indistinct. Terebra straight, 

 as long as the body. Size variable. ^ ? . Length, 1^ — 2 ; wings, 

 2|— 4 lin. 



Described from 5 females and 19 males. Taken by 

 Haliday in the woods of northern Ireland ; locally 

 common in England, and especially in a wood close to 

 my house at Niinton, Wilts ; I have also specimens from 

 Leicestershire and Herts. Wesmael possessed a series 

 taken on old palings and windows at Brussels ; he 

 suspected them to be parasites of Anobium.
