punctate-striate, with the granulations of the interstices 

 not arranged in such distinct rows. The rostrum and vertex 

 are more rugose-punctate, the punctures running into lon- 

 gitudinal rugulae ; the former, also, is distinctly keeled in 

 the middle, with an obsolete longitudinal furrow on each 

 side. The second joint of the funiculus should be almost 

 shorter than the first, instead of somewhat longer, as in 

 O. rugifrons. 



De Marseul attributes this species to Stephens, but there is 

 no reference to it in the '* Manual."

Mr. Crotch (loc. cit.) states that Dr. Power possesses 

 specimens of this species, that he has seen examples in other 

 collections, and that it is near M. pruni, but distinguished 

 at once by the singular antennce of the male. 



The antennae in both sexes of M. barbicornis have the 

 funiculus as well as'the scape rufo-testaceous ; and, compared 

 with 31, cerasi, the male clava is narrower, considerably 

 longer, and densely clothed with erect rigid hairs. The 

 elytra, also, are glossy, deeply sulcate, with the sulci faintly 

 punctured, and the interstices convex and finely coriaceous. 



Stephens' barbicornis is the male of 31. cerasi.

Mr. Crotch states that this insect must be regarded as 



new to our fauna, on the authority of a single specimen 



taken by him about three years ago at Cambridge, and 



named by M. Brisout ; the insect hitherto known to us by
