[169.] 223. MoNocHAMUS MARMORATOR Xÿrby.—Length of body 11 
lines. A single specimen taken in Lat. 54°. \ 
Body black, covered underneath, but so that the black appears in 
various places, with subcinereous, or somewhat tawny decumbent hairs. 
Head and prothorax covered in the same way but with redder hairs : 
spines of the prothorax very robust, rather long, sharpish: scutellum ~ 
covered with a coat of cinereous hairs, divided by a black longitudinal 
line: elytra black, marbled variously with cinereous and reddish tawny 
hairs; the cinereous spots are dotted with black; the surface of the 
elytra when laid bare appears punctured, and at the base are several con- 
fluent smooth elevated spaces ; suture and lateral margin testaceous ; apex 
acute.

with brown, with an oblique brown band a little beyond the middle, apex 
of the elytra rounded: podex and hypopygium, or last dorsal and ventral 
segments of the abdomen elongated, so as to defend the base of the ovi- 
positor which is exserted, causing the insect to appear as if it had a tail ; 
the hypopygium is emarginate : thighs much incrassated at the apex. [Not
