Black : vertex of the head, mesothorax, scutellum, and abdomen shining. 

 Male — Head finely reticulate, opaque in front ; mandibles pale yellow, rufo-pioeous 

 at the apices ; clypous sparingly covered with silvery hair ; antennee rather 

 long, sub-fusiform, the joints of the flagellum sub-monilifoi-m, the scape in 

 front white; mesothorax and scutellum very finely reticulate, the former 

 having from four to six indistinct longitudinal scratches ; metathorax coarsely 

 rugose ; tubercles white ; tegula) fasco-testaceous ; wings slightly iridescent, 

 the nervures pitchy ; the apices of the femora, the tibise, and tarsi ferruginous, 

 the hinder tibioD more or less stained with fuscous ; abdomen impnnotate, with 

 the base of the first segment constricted, and the last segment terminating in 

 an up -curved spine. Length 2 J — 3 lines. 



Female — This sex appears to difiFer from the male in being somewhat larger (3 — 3^ 

 lines), with the antennaa not thickened, and the legs paler, and in wanting the 

 up-curved spine at the apex of the abdomen. 



The thickened sub-moniliform antennae readily separate this species from its 

 congeners. It appears to be not uncommon in Germany, and in Scandinavia, 

 occurring in July and August. Wesmael says that it ia very rare in Belgium, the 

 male only having occurred. 



I captured four males of this species, entering the cracks in a gate-post near 

 Wall-holme, East Cumberland, in July, several years ago ; these I have submitted 

 to Mr. F. Smith, who confirmed my opinion as to their identity with P. monilicomis,
