Stout, black, the elytra throughout pale rufous ; integuments 

 polished; pubescence in great part denuded in the type but ap- 

 parentl^' rather short, sparse and comparativel}' inconspicuous, 

 erect along the sides of the bod}'; antennae short, incrassate, the 

 outer joints transverse. Prothorax three-fifths wider than long, 

 the sides parallel and broadly arcuate ; apical and basal angles 

 broadly rounded ; disk evenh' convex, finely and sparsely' punc- 

 tate. Elytra one-fourth wider than the prothorax and three 

 times as long, more coarsely and strongly and a little more 

 closely though still not densely- punctured. Length 5.5 mm.; 

 width 2.3 mm. 



Arizona (Gila.) The only known specimen is the unique type 

 in the cabinet of LeConte, from which the above superficial 

 notes were taken a few years since. It may be recognized b^' its 

 unusually large size and b}' its coloration. 



62. T. lobatiis ii. sp. — Subcyliudrical, convex, shining, black; legsbl.ick, 

 the tibiae and tarsi rufescent; antennae black, the funicle slightly rufescent 

 toward base; pubescence cinereous, subdecuml)ent, rather long and dense, in- 

 termingled with a few long blackish setae toward the sides of the pronotum, 

 the erect hairs of the elytra very coarse and abundant l)ut only moderately 

 long, inclined posteriorly and cinereous, longer at the margins. Head three- 

 fourths as wide as the prothorax, finely, sparsely piinctate, the frontal impres- 

 sions feeble; epistoma moderately short, impuuctate and thin toward apex; 

 labrum short and transverse though large, very broadly rounded; eyes rather 

 large; antennae distinctly incrassate, a little longer than the prothorax, clothed 

 densely with short stiff hairs, the penultimate joints transverse. Prothorax 

 three-fifths wider than long, the sides perfectly parallel and very feebly arcuate 

 almost throughout, feeljly sinuate toward the basal angles which are obtuse 

 but distinct, the base obliquely sinuate for a shoi't distance near the angles, 

 broadly and strongly arcuate in the middle; apex broadly arcuato-truncate, 

 fully as wide as tlie base or slightly Avider, the apical angles birt slightly ob- 

 tuse and blunt; disk finely, sjjarsely punctate, rugulose only very near the 

 lateral edges. Elytra about three-fifths longer than wide, only very slightly 

 wider than the prothorax, parallel, evenly rounded at apex, finely and some- 

 what closely punctate, the interspaces polished. Abdomen and legs only 

 moderately densely cinereo-pubescent. Length 2.7 mm.; width 1.1 mm.
