11. T. an I lira v Lee. — Form moderately elongate, convex. Color black, 

 shining, dead as wide as the thorax at apex ; eyes moderately large and promi- 

 nent; antennae less than one-half as long as the body, piceous, the basal joints 

 paler; palpi rufo-piceous. Prothorax subquadrate, about one-half wider than 

 long, very slightly wider at base than apex; apex truncate; anterior transverse 

 impression obsolete; median line fine, abbreviated in front and behind ; posterior 

 transverse impression deep, finely punctulate, tripunctate at middle; basal im- 

 pressions deep; base truncate; sides rounded in front, slightly sinuate behind, 

 the margin very narrowly re flexed ; hind angles rectangular, finely carinate. 

 Elytra oblong-oval, less than one-half wider than the thorax, with a deep sutural 

 stria and from one to three abbreviated dorsal stripe ; striae impunctate; first dor- 

 sal puncture about one-third from base, the second about one-third from apex. 

 Body beneath black, shining. Legs rufous or rufo-piceous, the femora darker. 

 Length .08-. 11 inch ; 2-2.75 mm. 



A well-marked and easily recognizable species. The posterior 

 dorsal puncture of the elytra is placed somewhat further behind the 

 middle than is usual in the present group. 



It occurs in California. 



12. T. liebulosus Chaud. — Form robust. Color varying from ferrugineous 

 to rufo-piceous, shining, the elytra usually with the sides and apex somewhat 

 paler. Head as wide as the thorax at apex; eyes large, prominent; antennae 

 nearly one-half as long as body, pale fuscous, the basal joints testaceous. Pro- 

 thorax subquadrate, wider at base than apex, scarcely one-half wider than long; 

 apex truncate; anterior transverse impression obsolete, the posterior distinct, 

 finely punctate, tripunctate at middle; median line very fine, abbreviated before 

 and behind; basal impressions distinct; base truncate; sides with the margin 

 very narrowly reflexed, slightly rounded to behind the middle, feebly sinuate in 

 front of the hind angles, which are rectangular and feebly carinate. Elytra 

 slightly wider than the thorax, oblong-oval, with the sutural stria deep, impunc- 

 tate, not attaining the base, the other dorsal striae obsolete ; first dorsal puncture 

 about one-fourth from base, the second very slightly behind the middle. Body 

 beneath rufo-piceous or ferrugineous. Legs testaceous. Length .08-. 11 inch ; 

 2-2 75 mm. 



This seems to be a well-marked species, subject to but slight varia- 

 tion. Its affinities are towards vivax on the one hand and incurvus 

 on the other. It is not, as a rule, very common in collections, and 

 large specimens of the latter are often referred to it. These may at 

 once be distinguished from the present species by the absence of the 

 three large punctures at the middle of the posterior transverse im- 

 pression of the thorax. 



It occurs in Louisiana, Texas, Colorado and Utah. A single ex- 

 ample labelled "Montreal, Can.," has been seen. 



13. T. liebecki n. sp. — Form very robust. Color dark rufo-piceous, very 

 shining, the elytra gradually paler towards the tip. Head as wide as the thorax 

 at apex ; eyes large, prominent: antennae scarcely one-half as long as the body,
