178 MEMOIRS ON THE COLEOPTERA 



Pronotum with a medio-subbasal puncture, the subbasal punctured sul- 

 cus being interrupted medially or not; sometimes the inner puncture 

 of the lateral rows of punctures may be slightly more pronounced, 

 giving a vague appearance of three punctures, a division by the 

 presence or absence of three punctures being therefore not always 

 wholly unequivocal 9 



7 Body very deep and uniform polished black, the under surface pice- 

 ous, the legs rufous. Head three-fifths as wide as the prothorax, 

 without evident sulci, the eyes rather small and very moderately 

 prominent; antennae fuscous, testaceous basally, three-fifths as long 

 as the elytra, slender basally, gradually feebly incrassate distally; 

 prothorax two-fifths wider than long, the sides rather strongly, sub- 

 evenly arcuate, extremely briefly subsinuate at the minutely sub- 

 prominent angles; subbasal punctate sulcus completely interrupted 

 medially, with an isolated medial fovea, the end punctures of the 

 lateral series rather more pronounced than the others, giving the 

 appearance of three medio-basal punctures; carina small and feeble, 

 the foveae shallow, remote from the carina; elytra oval, one-half 

 longer than wide, a third wider than the prothorax; sutural stria 

 deep, not attaining the base; outside of this a second excessively fine 

 feeble stria is sometimes glimpsible. Length 2.0 mm.; width 0.8 

 mm. California (Paraiso Springs, Monterey Co.). San Diego 

 LeConte anthrax Lee. 



Body virtually unicolorous, the elytra without obvious nubilously paler 

 areas. Color very dark rufous, the legs slightly paler; head small, 

 less than three-fifths as wide as the prothorax, with two very small 

 and feeble anterior frontal impressions; eyes moderate in size and 

 prominence; antennae slender, gradually very slightly incrassate dis- 

 tally, infumate, clearer basally, fully two-thirds as long as the ely- 

 tra; prothorax large, nearly one-half wider than long, wider at base 

 than apex, widest at about the middle, the sides subevenly and mod- 

 erately arcuate throughout; three subbasal punctures isolated and 

 distinct; foveae small, rounded, distant from the angles; carina small 

 but well defined; elytra one-half longer than wide, barely a fourth 

 wider than the prothorax, the coarse deep sutural stria not attain- 

 ing the base; foveae at third and three-fifths. Length 1.8-2.3 mm.; 

 width 0.75-0.85 mm. Texas (Galveston). Many specimens. 



solita n. sp. 



Body castaneous, the elytra with suffused slightly paler coloration ex- 

 ternally toward base, also posteriorly and sometimes laterally .... 8 



8 Form suboval, rather stout, very convex and highly polished; head 

 notably small, generally only a little more than half as wide as the 

 prothorax; eyes very moderate in size and convexity; anterior im- 

 pressions small and feeble; antenna? nearly as in the preceding; pro- 

 thorax not so large and much more rounded at the sides, two-fifths 

 wider than long, much wider at base than apex, the sides evenly, 

 subcircularly rounded, nearly straight basally, widest slightly be- 

 fore the middle; three subbasal foveae isolated and distinct; foveae 

 small, deep, distant from the angles, which are briefly carinate; 

 elytra not quite one-half longer than wide, nearly two-fifths wider
