Coleopterological Notices, VII. 629 



T. semiruber. — Moderately stout and convex, highly polished, dark red- 

 brown, the elytra pale rufous, the abdomen black and the legs and antennte 

 pale testaceous; integuments subimpunctate, the punctules of the elytra and 

 abdomen extremely minute and rather sparse; pubescence moderately short, 

 rather fine, sparse, strongly recurved and not very conspicuous. Head small, 

 distinctly narrower and shorter than the prothorax, shorter than wide, the 

 eyes rather small, at more than their own length from the base, the latter cir- 

 cularly rounded; fovese normal. Antennse scarcely % ^-s long as the body, un- 

 usually slender, the club gradual and relatively strong; joints smooth, polished 

 and subimpunctate throughout, except the last three, which are sparsely ru- 

 gose; three to five distinctly elongate, the sixth slightly and the eighth just 

 visibly, longer than wide ; seventh quadrate ; ninth very distinctly elongate, 

 the tenth rather longer than wide; eleventh obliquely pointed as usual. Pro- 

 thorax not quite as long as wide, widest and subprominently rounded near apical 

 third, the sides feebly convergent and somewhat sinuate thence to the base ; 

 apex about }{ the maximum width and % as wide as the base; disk and trans- 

 verse groove nearly as in the preceding species, not distinctly punctured near the 

 base. Elytra fully 3^ wider than long, % longer than the prothorax and twice 

 as wide; humeri moderately prominent, the sides distinctly divergent and 

 broadly, distinctly arcuate thence to the apex; discal groove very broad toward 

 base, fine posteriorly, ending at apical fifth. Abdomen rather wider and much 

 longer than the prothorax, the sides parallel and arcuate; border wide and flat; 

 basal carina well developed in basal %. Length 1.7 mm.; width 0.78 mm. 



Lake Superior. 



The single male type in my cabinet has the intermediate tro- 

 chanters obliquely prolonged in a shorter, more pointed and less 

 curved process than in the preceding, the tibiae arcuate and thick- 

 ened, the anterior trochanters prominent within at tip and the 

 femur with a strong but short inferior carina just behind the mid- 

 dle. The body is narrower, the antennse shorter and more slender, 

 the prothorax shorter and broader, the elytra less transverse and 

 with longer discal stria, and the integuments less punctured and 

 less densely pubescent than in humeralis. 



T. coiisimilis. — Stout and convex, shining and subimpunctate ; body, 

 legs and antennae red-brown, the elytra paler, bright rufous, the abdomen 

 black ; pubescence rather long, abundant, recurved and conspicuous. Head 

 wider than long, nearly as wide as the prothorax. Antennse % as long as the 

 body, stout, the club rather large and paler in color. Prothorax slightly trans- 

 verse, widest and slightly rounded near apical third, the apex wide, % the 

 maximum width and nearly % as wide as the base ; disk nearly as in the pre- 

 ceding species. Elytra very transverse, % wider than long, % longer than the 

 prothorax and a little more than twice as wide ; sides moderately divergent, 

 broadly and distinctly arcuate ; discal impression very broad toward base as 

 usual, vanishing at apical fourth. Abdomen rather wider and distinctly longer
