Black : vertex of the head, mosothorax, scutollnm, and abdomen shining. 
Male — Head finely reticulate, opaque in front ; mandibles pale yellow, rufo-piooous 
at the apices ; clypous sparingly covered with silvery hair ; antenna) rather 
long, sub-fusiform, the joints of the flagellum sub-moniliform, the scape in 
front white; mosothorax and scutellum very finely reticulate, the former 
having from four to six indistinct longitudinal scratches ; metathorax coarsely 
rugose ; tubercles white ; tegula) fiisco-tostaceous ; wings slightly iridescent, 
the norvures pitchy ; the apices of the femora, the tibice, and tarsi ferruginous, 
the hinder tibiaa more or less stained with fuscous ; abdomen impunctate, with 
the base of the first segment constricted, and the last segment terminating in 
an up-curved spine. Length 2^ — 3 lines. 
Female — This sex appears to differ from the male in being somewhat larger (3 — 3^ 
lines), with the antenna} not thickened, and the legs paler, and in wanting the 
np-cui-vod spine at the apex of the abdomen. 
The thickened sub-moniliform antennae readily separate this species from its 
congeners. It appears to bo not uncommon in Germany, and in Scandinavia, 
occurring in July and August. Wesmael says that it is 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,
