abdomen narrower than the elytra, parallel and straight at the sides 

 throughout, finely, sparsely punctured, the basal parts of the tergites 

 impunctate; mesosternal process acute, with a longer sloping posterior 

 margin than in any other species, the apparent distance between the 

 two apices being therefore greater. Length 3.0-4.0 mm.; width 

 0.75-0.8 mm. New York to Virginia (Norfolk) maritima Csy . 



Species of the Pacific Coast 2 



2 — Antennae stout and strongly incrassate, the ante-apical joints strongly 

 obtrapezoidal, short and very strongly transverse, the second and third 

 joints moderately elongate, subequal in length, the former somewhat 

 the shorter; basal joint of the hind tarsi as long as the third and fourth 

 combined. Body stout, parallel, opaque, the elytra less so, the abdo- 

 men shining, black, the entire elytra dark rufo-piceous; legs red-brown, 

 the antennae inf uscate ; vestiture short and inconspicuous, rather sparse ; 

 head large, subquadrate, wider than long, three -fourths as wide as the 

 prothorax; finely, somewhat sparsely punctate, the median line im- 

 punctate as usual; antennae slightly shorter than the head and pro- 

 thorax, the latter large, more transverse, a third wider than long, par- 

 allel and evenly, rather strongly rounded at the sides, the base almost 

 continuously and strongly arcuate, the angles very obtuse and barely 

 visible; punctures fine, not very distinct, well separated and evenly 

 distributed throughout; elytra distinctly wider and somewhat longer 

 than the prothorax, the sides evidently longer than those of the latter, 

 the suture scarcely as long as the median line, the punctures fine, mod- 

 erately close-set and rather distinct; abdomen nearly as wide as the 

 elytra, parallel, finely, sparsely punctate, the punctures very remote 

 toward apex, the impressions impunctate as usual; mesosternal process 

 acute, the space between the two apices unusually deeply excavated. 

 Length 3.5 mm. ; width 1.0 mm. California (Sta. Barbara and La Jolla). 



paciflca Csy. 



Antennae less strongly incrassate distally, the outer joints less narrowed 

 from apex to base and less strongly transverse, the second joint always 

 longer than the third; basal joint of the hind tarsi still shorter, but 

 little longer than the second 3 



3 — Second antennal joint only very slightly longer than the third. Form 

 only moderately stout, parallel, dull in lustre, the abdomen polished, the 

 vestiture moderate in length and abundance though distinct, black, the 

 elytra very dull rufo-piceous, black at the sides, the legs pale red- 

 brown, the antennae nearly black; head relatively large, four-fifths as 

 wide as the prothorax, finely, strongly punctured except along the mid- 

 dle, the antennae about as long as the head and prothorax, the latter a 

 fifth wider than long, parallel, with evenly and moderately arcuate sides 

 and rounded base, the punctures fine but distinct and rather close, the 

 surface somewhat flattened toward the middle, with two feebly tumes- 

 cent smoother spots at the basal margin and separated by half 

 the width; elytra but slightly transverse, much wider and evidently 

 longer than the prothorax, the suture as long as the median line, the 

 punctures rather fine but strong, somewhat close-set; abdomen nar- 

 rower than the elytra, parallel throughout, the punctures fine and sparse, 

 wanting at the bases of the tergites; mesosternal process acuminate, the
