throughout ; outer acute edge very feebly and gradually reflexed near the 

 apex. Abdomen coarsely, very densely cribrate, the punctures polygonally 

 crowded ; pubescence very fine, not conspicuous, that of the pubescent area 

 of the last segment very short and fine, the same segment convex, not im- 

 pressed. Length 1.7 mm. 



California (San Bernardino), LeConte ; Texas (Austin) Auct. 



The exceedingly coarsely and densely cribrate upper surface, and 

 coarse mottled pubescence will at once distinguish this very inter- 

 esting species. 



l«. Olivaceiis Lee. — Proc. Acad. Nat. Sci. Phila., VII, p. 116. — Oval, con- 

 vex, in form and color nearly as in punctatus; pubescence confusedly mottled 

 cinereous and fulvous, rather sparser than in punctatus; integuments polished. 

 Head rather coarsely, very deeply aud evenly punctate, the punctures dense 

 but distinctly separated. Prothorax rather more than twice as wide as long, 

 the basal lobe narrow but well developed, truncate ; sides feebly, evenly 

 arcuate ; median impressed groove distinct but not extending much in advance 

 of the centre ; punctures equal in size to those of the elytra and equally sparse. 

 Elytra nearly four times as long as the prothorax ; sides distinctly, broadly 

 arcuate, toward base coarctate with those of the prothorax ; apex rather acute ; 

 surface very evenly, rather sj^arsely punctate, the punctures round, deep and 

 perforate, separated by one-half more than their own diameters. Prosternura 

 shining, deeply grooved, strongly punctate, the punctures separated by their 

 own widths ; femora very coarsely, deeply punctate, the metasternuni much 

 more sparsely so. Abdomen coarsely and very densely punctate toward the 

 sides, much more finely so — the punctures separated by more than three times 

 the distance — toward the middle and base. Length 2.1 mm.

The form described by LeConte as oHvaceus has given rise to 

 more or less divergence of opinion. Henshaw in his list of the 

 species described by J. L. LeConte (p. 230), states that it is a valid 

 species. Dr. LeConte in his most recently published table of the 

 genus (Bull. F. S. Geol. Surv., Y, 1879, p. 515) unites it in 

 synonymy with punctatus, and Henshaw in his check-list of North 

 American Coleoptera, appears to coincide with this opinion. I have 

 personally examined the specimen in the cabinet of LeConte which 

 bears the type label, and find that it is absolutely identical with the 

 type of punctatus, the punctuation being fully as dense as in that 

 species. Schwarz has taken in abundance at Detroit, Mich., a 

 species — described above — which is allied to, but certainly distinct 

 from, punctatus, having the elytral punctuation decidedly sparser 

 but not quite as coarse ; it is the opinion of Mr. Schwarz that this 

 is the true olivaceus.
