wide and of almost equal width from the base to within a short 

 distance of the apical angles, where they become rapidly nar- 

 rowed. Anterior coxae moderately separated, the intermediate 

 more widely, the process of the mesosternum slightl}' tumid and 

 anteriorly excavated to receive the prosternal process ; posterior 

 separated by two-thirds of the coxal width, the abdominal process 

 broadl}" rounded. Met-episterna narrow and parallel. Legs short 

 and stout; tibiae tricarinate externally; tarsi thick, the last joint 

 of the posterior as long as the preceding three. 



M. sequoiaruiil n. sp. — Oblong, strongly convex, opaque throughout, 

 .black and glaljrous. Head not coarsely Ijut strongly scabro-punctate, with a 

 tuberculiforni elevation above each eye; antenna* as long as the width of the 

 head, the three outer joints broader and minutely, densely pubescent, joints 

 before the club triangular, ninth and tenth strongly transverse. Prothorax 

 fully twice as wide as long, twice as wide as the head, the apex three-fourths 

 as wide as the base; sides evenly arcuate throughout and strongly crenulate; 

 apical angles advanced ; base arcuate, becoming obliquely sinuate toward the 

 sides; disk rather abruptly and broadly reflexed toward the sides, covered 

 with coarse separated tubercles, sulcate along the middle, the sides of the sul- 

 cus becoming carinate anteriorly in the male but simply tumid in the female. 

 Elytra parallel, subequal in width to the prothorax, about two-fifths longer 

 than wide, broadly but evenly rounded at apex; side margins slightly promi- 

 nent, more so and cariniform toward apex, strongly creniilate, not at all re- 

 flexed; disk vertical at the sides, having regular series of rather coarse, close- 

 set, opaque tubercles, the intervals each with a series of coarse and rounded 

 punctures separated by small tubercles; third, fifth and seventh series of 

 tubercles more prominent, the third especially so toward the summit of the 

 apical declivity, which is almost vertical in profile. Abdomen strongly and 

 closely punctate, the legs less coarsely, strongly and very densely punctate. 

 Length 6.5-7.0 mm.; width 3.4-3.6 mm.

The sexual differences are very feeble, the male having the sides 

 of the pronotal sulcus more prominent and laminate toward apex, 

 as stated, and the general form of the bod}' sensibly shorter. Sev- 

 eral specimens.

The following studies were undertaken largely for the purpose 

 of identifying and naming a consideral)le number Of nondescripts, 

 which have been accumulating for many years, but, at the same 

 time I have become much interested in the general grouping and 

 classification of the genera, points which were left in a very un-
