HERPALIN.E 189 



shining but distinctly alutaceous; head smooth, very shining and 

 virtually punctureless, the foveae linear and outwardly arcuate as in 

 the pieceding, the antennae nearly similar; eyes more convex in the 

 male than in the female; prothorax rounded at the sides, the latter 

 converging and broadly, feebly sinuate posteriorly, the basal angles 

 obtuse but with the apices slightly prominent, forming a right angle; 

 base broadly and very feebly sinuate medially, not very obviously 

 wider than the apex, which is moderately sinuate ; surface veryJshining, 

 impunctate centrally, the punctures laterally and apically extremely 

 fine, sparse, those basally also very fine and sparse throughout 

 except in the rather large and subelongate, moderately deep foveae, 

 where they are strong and dense; marginal gutter fine, deep and 

 nearly constant in form from apex to base, obsolete only at the basal 

 angles; stria fine but rather deeply impressed, subentire; elytra 

 nearly one-half longer than wide, parallel, with broadly arcuate 

 sides and obtuse and rather strongly sinuate apex, fully a fifth wider 

 than the prothorax; striae and intervals nearly as in the preceding, 

 except that at apex the intervals become more evidently convex than 

 in angustus; hind tarsi moderately slender, the basal joint much 

 longer than the fifth in both sexes. Length (cf 9 ) 10.8-11.8 mm.; 

 width 3.8-4.3 mm.; Oregon oregonus n. sp. 



Body still noticeably broader than in oregonus. though not stout, more 

 parallel, the head nearly similar but with slightly larger eyes, the 

 foveae well developed and of different form, being rounded and very 

 deep to angulate; prothorax rounded at the sides, the latter con- 

 verging posteriorly and broadly, feebly sinuate, the basal angles 

 slightly obtuse and sharply defined though scarcely at all prominent; 

 surface strongly shining and with extremely fine or obsolete punctures 

 everywhere except in the large, centrally very deep foveae, where 

 they are very coarse and coalescent, gradually becoming finer 

 outwardly, the marginal gutter differing somewhat in being very 

 fine anteriorly, sensibly increasing in width posteriorly, then be- 

 coming obsolete toward base; apex rather deeply sinuate, a little 

 narrower than the rectilinear base; elytra long, rather more than 

 one-half longer than wide, parallel, with feebly arcuate sides and 

 rather obtuse apex, the sinus unusually distinct; striae and intervals 

 neaily as in oregonus in both sexes, the very minute sparse suffused 

 punctulation is however rather evident (c?) or scarcely traceable 

 (9); hind tarsi nearly similar. Length (cf 9 ) 9.6-12.0 mm.; 

 width 3.8-4.7 mm. California (abundant about San Francisco, Sta. 

 Cruz and in Humboldt Co.). [A. confusus Lee.]. . californicus Dej. 



Body larger than in californicus and still stouter, the prothorax relatively 

 more developed and the eyes distinctly larger, the central rufous 

 spot of the vertex strongly transverse; head finely, sparsely and 

 obsoletely punctulate, the foveae rather large, deep, rugulose and 

 angulate, the epistoma with many longitudinal wrinkles; antennae 

 slender, extending well behind the thoracic base even in the female; 

 prothorax in outline, structure and sculpture almost as in cali- 

 forniciis, but with the anterior transverse impression medially deeper 

 and very obvious, the stria fine, coarser basally, obliterated apically;
