IO4 MEMOIRS ON THE COLEOPTERA 



basal stria rather long and distinct; hind legs (cf) scarcely modified, 

 the tarsi short,Jmoderately stout, the outer groove of the first joint faint 

 and coming far from attaining the apex. Length (cf 9 ) 9.4-10.7 mm. ; 

 width 3.4-3.8 mm. California (coast regions north of San Fran- 

 cisco), [scutellaris Lee.] brunneus Dej. 



Body still smaller, elongate-suboval, rather strongly convex, black, 

 shining, the elytra alutaceous and with faint violaceous suffusion; 

 under surface, legs and antennae dark reddish-brown; head mod- 

 erate, the impressions deep, parallel, internally arcuate and extend- 

 ing to the line of the anterior limit of the eyes; labrum truncate, the 

 epistoma sinuato-truncate; prothorax in outline as in the preceding, 

 the inner of the two impressions rectilinear and sharply defined, 

 the outer almost obsolete; elytra oval, almost equally convex 

 throughout, rather more than one-half longer than wide and nearly 

 a fourth wider than the prothorax, striae fine though rather strongly 

 impressed, impunctate, the intervals feebly convex internally to 

 strongly so externally, the humeral denticulation extremely minute; 

 supplemental or scutellar stria short but distinct, oblique; hind 

 tarsi more slender than in any of the preceding species, the basal 

 joint much shorter than the next two combined, the external groove 

 shallow but entire, the fourth joint nearly one-half longer than 

 wide. Length (9) 8.7 mm.; width 3.2 mm. A single example 

 unlabeled in the Levette collection but undoubtedly from the 

 Pacific coast and probably from California. The species rightfully 

 belongs to the amethystinus series, but has very much more slender 

 tarsi, having more triangular and not cordiform joints. . jejunus n. sp.

io Elytra short, scarcely more than a third longer than wide and 

 sexually nearly similar in lustre and striation. Body notably short 

 and stout in form, somewhat convex, polished, the elytra strongly 

 alutaceous, with the micro-reticulation distinct; head almost three- 

 fourths as wide as the prothorax, the distinct subparallel impressions 

 separated by nearly one-half more than either from the sides, the 

 epistoma and labrum rather broad, evenly and very distinctly 

 sinuate from side to side; antennae moderate, pale brownish-testa- 

 ceous, the four basal joints abruptly blackish-piceous; prothorax 

 large, just visibly wider than long, the sides feebly and irregularly 

 crenulate, broadly rounded, becoming moderately convergent and 

 broadly, feebly sinuate to the right and rather sharp angles, the 

 base broadly sinuate medially; impressions large and deep, one- 

 third as long as the disk, the concavity limited externally by a short 

 feeble longitudinal ridge near the margin, extending to the base; 

 elytra broadly, evenly convex, opaculate in both sexes, with rather 

 fine impunctate and moderately impressed striae, the intervals 

 broadly and only very feebly convex, more distinctly laterad, oblong- 

 oval, broadly, obtusely, rounded behind, fully two-fifths wider than 

 the prothorax, the scutellar stria distinct, oblique; legs rather slender, 

 the hind tibiae (cf ) with a few broadly rounded and very feeble 

 crenules internally, wanting ( 9 ) as usual, the tarsi slender, the first
