anterior part hardly rounded outwardly, and gradually narrowed 

 towards the base ; elytra more elongated in proportion to the length 

 than in rugosopunctata, and more convex, each one with seven 

 equally raised sharp costae, and the intervals with a series of broad 

 punctures, apical part of the suture slightly notched. 



More slender than the preceding species, and elytra more elongato- 

 ovate ; prothorax somewhat in the shape of a truncated cone. 

 Length 15-17 mm. ; width 5-6 mm.

Head of M. tabida, atrata, &c. ; palpi, tarsi, and first joint of antennae 

 ferruginous red ; prothorax truncate at the apex, with the anterior 

 angles hardly projecting, hardly ampliated in the middle, gradually 

 attenuated from there to the base, which is less than half as broad 

 as the anterior part, closely punctured with the usual median longi- 

 tudinal depression ; elytra ampliated in the middle, with the outer 

 sides from there nearly straight, notched at the apex of the suture, 

 plane, but less so in the anterior than in the posterior part, each one 

 with seven sharp equal costae from base to apex, and having a dis- 

 tinct series of small punctures on each side, intervals with a series 

 of narrow, moderately deep punctures. Length 16 mm. ; width 

 6 mm. 



The elytra are more narrowed in front than in any of the other 

 species, the prothorax is also more slender.

Mentum with the lobes broad, much rounded at the upper part, 

 the inner edge carinated, nearly straight for two-thirds of the length, 

 slightly sinuate at the tip, which ends in a short, sharp tooth ; 

 ligula spatuliform and convex for half the length, the other half very 

 narrowed and fused with a moderately broad paraglossa on each 

 side, diagonally truncate at the tip, with the outer angle acute and 

 projecting a little; maxillary and labial palpi of Anthia ; labrum 

 short, subtruncate at the apex without any incision ; head broad, 

 hardly narrowed behind ; prothorax plane, gradually decreasing from 

 the anterior part towards the base, which is truncate and about 

 half the width of the apex ; elytra elongate, almost subparallel, 

 moderately plane, the posterior outer margin truncate, nearly 

 straight ; male with the three basal joints of the anterior tarsi 

 dilated inwardly.
