i8o MEMOIRS ON THE COLEOPTERA 



ate; deep sutural stria distinctly abbreviated at base, exactly as in 

 nebulosa, from which the present species differs in coloration and in 

 the narrower form, as stated, and in its relatively smaller head and 

 prothorax. Length 2.1-2.35 mm.; width 0.8-0.95 rnm. Utah 

 (Provo and neighboring regions), YVickham. Many specimens. 



sectator n. sp. 



A Almost similar to sectator but slightly more elongate and larger 

 in size, the prothorax more rapidly narrowed basally, the three 

 subbasal punctures similarly isolated; elytra slightly more elon- 

 gate, more gradually obtusely acuminate at apex; sutural stria 

 almost as abbreviated at base. Length 2.25-2.4 mm.; width 0.83 



-0.93 mm. Arizona. Four examples sospes n. subsp. 



9 Ground color piceous or castaneous to rufo-testaceous 10 



Ground color deep black, highly polished as usual 13 



10 Elytra somewhat as in the preceding section, having each two very 



nubilously indefinite paler areas 1 1 



Elytra uniform in color, or without two paler areas 12 



II Body oblong-oval, convex, moderately stout, piceous to castaneous, 

 the elytra marked as in nebulosa; head nearly three-fifths as wide as 

 the prothorax, the eyes rather well developed and prominent; an- 

 terior impressions very feeble; antennae fuscous, paler and more 

 slender basally, three-fifths as long as the elytra; prothorax rela- 

 tively large, one-half wider than long or nearly, widest but little 

 before the middle; base much wider than the apex; sides almost 

 evenly and strongly rounded throughout, straight near the obtuse 

 basal angles; arcuate subbasal sulcus finally punctate; a larger me- 

 dial puncture is more or less isolated; foveae shallow and indefinite; 

 carina small; elytra rather more than one-half longer than wide, 

 barely a third wider than the prothorax, parallel, obtusely ogival at 

 apex, the sides very gradually rounded toward the humeri; deep 

 sutural stria moderately abbreviated at base; outside of this coarse 

 sutural stria a second, extremely fine, may sometimes be discovered; 

 foveae at basal third and behind the middle. Length 1.72.3 mm.; 

 width 0.6-0.8 mm. Rhode Island and North Carolina to Minne- 

 sota and Arkansas. Very abundant, the series at hand numbering 

 more than sixty specimens. [T. puhhellits Lee. nee Laf. ; anceps 



Lee.] incurva Say 



Body somewhat as in incurva in outline and coloration, but larger and 

 stouter, the prothorax widest less medially; head four-sevenths as 

 wide as the prothorax, the eyes moderate in size and prominence; 

 antennae similar; prothorax large, not quite one-half wider than long, 

 widest at anterior two-fifths; sides well rounded anteriorly, nearly 

 straight and oblique in about basal half; finely punctate subbasal 

 sulcus entire, the large medial puncture slightly isolated foveae at 

 the outer ends of the sulcus as usual, small but rather deep; elytra 

 oblong, parallel, obtusely ogival behind, more than one-half longer 

 than wide, scarcely a third wider than the prothorax; striae as in 

 incurva, except that the sutural stria more nearly attains the base, 

 sometimes entirely so; foveae at two and four sevenths. Length 2.3
