Hertd minutely punctate. Rostrum very short. Antennse 

 extending beyond posterior coxa?, flattened; 1st joint obtriangular, 

 distinctly shorter than 3rd, 2nd concealed, 3rd-10th serrate, 3rd 

 slightly longer than 2nd, 2nd-10th subequal, 11th elongate. 

 Prothorax seven-areolate ; scarcely transverse ; base distinctly 

 wider than apex, bisinuate, middle notched ; posterior angles 

 acute ; sides strongly lessened to middle. Smitellum oblong, 

 grooved, sides incurved near apex, apex emarginate. Elytra 

 wider than prothorax, increasing in width to apex; each with 

 four costpe of which the 2nd and 4th are thicker, though not so 

 thick as the margin; interspaces with two series of comparatively 

 small punctures, near margiii distinct to apex, the others in two 

 series onl}' near base, becoming very irregular from near middle 

 to apex. Penultimate segment of abdomen rather feebly incised. 

 Length 11, width 4^ mm.

Differs from J/, hif/ubris in being larger, prothorax bicoloured 

 and elytra somewhat differently coloured; from the description of 

 21. mo)iticola, to which species it is perhaps closer, by the elytral 

 puncturation less coarse than in J\L erythropfenis, and extremely 

 irregular, apparently in a different fashion to that of M. monti- 

 coJa ; the black elytral patch (perhaps, however, variable) is 

 different from that of M. monticola, which Mr. Blackburn says " is 

 of a width to include two costa;;" in this species it includes four, 

 and is sharply defined except towards the apex.

r^. Sooty-black; sides of prothorax, margins and extreme apex 

 of elytra yellowish; yellow produced on suture for about one-tenth 

 its length and for about the same length on 2nd costa; under 

 surface of 1st antennal joint and trochantins obscure testaceous. 

 Face with whitish pubescence. 



Head with a transverse foveate impression between eyes. 

 Rostrum very short. Antennae rather short, 1st joint distinctly 

 shorter than 3rd, 2nd concealed, 3rd-10th serrate, 3rd-8th sub-
