convergent carinse and three pubescent foveas, and the metasternum 

 in the middle one-half longer than the intermediate coxae. The an- 

 terior coxas are long and conical, the intermediate narrowly sepa- 

 rated by the meso- and metasternal processes which meet jast before 

 their median line, the posterior transverse, contiguous, moderately 

 prominent internally. Abdomen with six dorsal and seven ventral 

 segments, the first ventral unusually long, greatly visible behind 

 the coxae throughout, and, in the middle, nearly one-half as long as 

 the second, the latter very large, as long as the entire remainder ; 

 first dorsal covered, the second much longer than the third, with a 

 deep, transversely oval and pubescent excavation at the middle of 

 the base ; margin moderately wide, inclined. 



There appears to be but one species as follows : — 



M. OCCidens n. sp. — Moderately stout and convex, polished, dark rufo- 

 testaceous throughout, subimpunctate, the elytra coarsely sparsely and very 

 I'eeb]^^ rugoso-punctate ; pubescence long, coarse, erect, not very abundant 

 except at the antero-lateral and under surfaces of the head where it is erect 

 bristling and very dense. Head as wide as the prothorax, as long as wide ; 

 eyes small, just behind the middle ; outline behind them almost semi-circu- 

 lar ; fovese on a line through the eyes, distant by one-half the total width ; 

 antennae a little longer than the head and prothorax, stout, first joint cylin- 

 drical, longer than wide, second a little narrower, globular, three to eight still 

 slightly smaller, transverse, five and seven larger than six and eight, ninth 

 and tenth larger, transverse, eleventh subquadrate, broadly conical at apex. 

 Prothorax nearly as wide as long, widest at apical third, the sides thence feebly 

 convergent and straight to the base but with a shallow emargination midway, 

 strongly convergent and sinuate anteriorly to the neck, the latter two-thirds 

 as wide as the base ; disk with a strong transverse excavation at basal third 

 from side to side, divided into three parts by two cariniform elevations, the 

 lateral portions irregular and continued to the base, the median consisting of 

 three large coalescent fovese, the middle one more posterior, continued forward 

 beyond the center of the disk by an almost imperceptible impression ; surface 

 just before the basal margin divided into five nearly equal deep impressions 

 by four short longitudinal carinse, the lateral communicating with the irregu- 

 lar lateral impressions as before mentioned, and the middle one similarly with 

 the median discal impression, the two others deeper and more fuveiform. 

 Elijtra short, two-fifths wider than long, one-half longer than the prothorax 

 and fully twice as wide, one-half wider near the apex than at base ; sides 

 strongly oblique and nearly straight ; humeri obsolete ; disk with the single 

 arcuate sutural stria only, also with a deep stria and post-humeral fovea on 

 the flanks, each with four basal fovese, the two infra-humeral coalescent and 

 prolonged posteriorly for a very short distance as a broad gradually evanes- 

 cent impression ; intermediate fovea isolated, without trace of stria. Abdomen 

 fully as wide as the elytra and distinctly longer. Lega slender ; posterior
