equally arcuate; disk iniimtely and remotely punctate, not at all rujiose later- 

 ally. Elytra three-fifths lon<ier than wide, slightly wider than the prothorax, 

 parallel and straight at the sides, the apex evenly and not very broadly 

 ronuded; disk coarsely, rather sparsely and somewhat unevenly punctate. 

 Abdomen and legs rather finely and not densely cinereo-puhescent. Length 

 2.4 mm. ; width 0.9 mm. 



California. 



The male above described has the fifth ventral simple, rather 

 short and broadly truncate. Along the suture and on the flanks 

 of the eh'tra a few cinereous hairs are sparsely scattered, but 

 these are extremely inconspicuous in the two specimens before 

 me, and, in case they should become denser by variation, the 

 species may be readily known from sutiwalis b}' its much smaller 

 size, narrower form, smaller, shorter and relatively narrower pro- 

 thorax and relatively still coarser, though scarsely sparser, elytral 

 punctures. 



84. T. politus n. sp. — Subcylindrical, strongly convex, highly polished, 

 deep black, the legs black ; antennse black, with the funicle slightly piceous 

 toward base; pubescence fine and suberect, very sparse, blackish, the surface 

 bristling also with very numerous long erect and black seta% a few short but 

 coarser cinereous hairs scattered narrowly on the elytral flanks toward base, 

 the marginal cilia black throughout. Head four-fifths as wide as the pro- 

 thorax, smooth, finely and sparsely punctate, the impressions rather large, 

 elongate, widely separated but distinct; epistoma moderately transverse; 

 labrum rounded; eyes rather large and prominent; antennae a little longer than 

 the prothorax, feebly iucrassate, the penultimate joints distinctly transverse, 

 fifth noticeably dilated. Prothorax notably convex; three-fifths wider than 

 long, the sides parallel and strongly arcuate; basal angles very obtuse but not 

 obliterated, the apical very obtuse; apex arcuato-truncate, the base visibly 

 more arcuate; disk finely and remotely punctate, not rugose laterally. Scutel- 

 lum finely and not very densely cinereo-pubescent. Elytra three-fifths longer 

 than wide, very slightly wider than the prothorax, the sides subparallel ; apex 

 evenly and not broadly rounded, the sutural angles right and not rounded; 

 disk coarsely, deeply and rather sparsely punctate, the interspaces smooth and 

 polished. Abdomen thinly clothed with fine plumbeo-cinereous pubescence. 

 Length 2.9 mm. ; width 1.2 mm. 



California (San Diego). Mr. Dunn, 



The two males before me represent a species which ma}^ be 

 known at once fi'om rusticus b}' the strongly rounded sides of the 

 prothorax, and, from aenescens, it may be distinguished by the 

 less sparse and deeper elytral punctures. The fifth ventral is 

 rather short and is broadly sinuato-truncate at apex.
