TRIBE HELOPININI. 

 GEN. MICEANTBEEUS, Sol. 



MlCBANTEBEUS CAPICOLA, n. Sp. 



Black, opaque, elytra covered with a greyish-brown, extremely 

 short pubescence, but with the granules and tubercles glabrous and 

 shining; the head is clothed with very short, appressed whitish- 

 grey hairs and is of the usual shape ; the prothorax, which is also 

 clothed with an appressed pubescence similar to that on the head, is 

 very closely and finely punctulate except on two small discoidal 

 denuded patches equi-distant from the outer margin and from a 

 fine, median longitudinal line, it is almost equally ampliated and 

 rounded laterally in both sexes in proportion to the size ; the female's 

 being wider than the male's ; the elytra of the former are elongate- 

 ovate and have on each side two dorsal rows of non-coalescing 

 conspicuous tubercles and an outer one the tubercles of which do 

 not, however, assume a costal appearance, the intervals are filled 

 with scattered tubercles which are more numerous in the anterior 

 than in the posterior part, and the suture is carinate ; in the female 

 the elytra are broadly ovate, and the tubercles in the intervals some- 

 what more numerous ; the abdomen and pectus have a faint bluish- 

 black tinge, and are very shiny ; the legs are very closely foveolate- 

 punctate, and the basal joint of the anterior tarsi of the male is not 

 much dilated. 



Undoubtedly closely allied to M. longipes, Fahr. ; the two sexes 

 are, however, more ovate, the tubercles on the two dorsal rows are 

 not so closely set and do not coalesce in the posterior declivity so as 

 to form more or less sharply carinate costae. 



Length 16^ mm. ; width 10-11 mm.

Closely allied to N. vicarius, differs from it merely by the broader 

 elytra which are also more obliquely ampliated laterally behind the 

 shoulders, the costae on the elytra are much more raised, the first 

 dorsal one is plainly divaricating towards the base, whereas they are 

 straight in M. vicarius, and the second and third intervals are much 

 more conspicuously tuberculate ; the female resembles that of
