large as those of excavatus but in the same positions; tarsi slender, 

 finely grooved laterally. Length (9) 7-5 mm.; width 2.9 mm. 



Ontario (Toronto), — R. J. Crew ontarionis n. sp. 



Form not so stout as in excavatus and not quite so convex, smaller in 

 size; coloration and lustre almost similar, the knees not so dark; 

 head nearly similar but with rather smaller though more prominent 

 eyes, the impressions similar; mandibles rufous, darker basally; an- 

 tennae slender, similar in coloration but not so elongate, half as long 

 as the body; prothorax smaller, rather less than one-half wider than 

 long, the sides subevenly and somewat more strongly arcuate, very 

 finely reflexed, becoming straight basally, the angles very obtuse but 

 with the tips rather sharply defined though not at all denticulate; im- 

 pressions and foveae nearly as in excavatus; base more abruptly oblique 

 at the sides, the apex rather narrower and more sinuate; elytra nar- 

 rower, two-fifths longer than wide, about twice as wide as the pro- 

 thorax, otherwise nearly as in excavatus in outline, the sinus a little 

 more oblique and perhaps not quite so shallow; striae and flat inter- 

 vals nearly similar, the minute punctulation rather more obscure; 

 three large foveae similar but not so deep or conspicuous, situated as 

 usual, the anterior near the third, the other two near the second, 

 stria; met-episterna twice as long as wide; anterior male tarsi still 

 more feebly dilated, the posterior shorter, especially in the first two 

 joints, and much shorter than the tibiae. Length (cf) 6.0 mm.; 

 width 2.3 mm. A single example unlabeled in the Levette collec- 

 tion and probably taken in Indiana trinaiius n. sp. 



In some species of other subgenera there is a feeble Indentation 

 of the elytral surface near the apex; this indentation would appear 

 at first sight to be accidental, but it proves to be a constant struc- 

 tural character; the. indentation is large and shallow in reflexus 

 Lee, and narrower and more external in cincticollis Say. Through- 

 out the present section this singular indentation exists; it is small, 

 rounded and near outer third. 



A rather notable peculiarity of this section exists in the position 

 of the ninth elytral stria, which is so close to the margin as to be 

 seen with difficulty; this stria is usually separated from the margin 

 by a much less narrow interval. In excavatus the scutellum is 

 rather large and parabolic; in trinarius it is much smaller, shorter 

 and triangular. 



Section Stictanchus. 



This is the largest group of the subgenus Pseudanchus and is 

 distinguished from the others primarily by having four or five to 

 six or seven punctures in the dorsal series of the elytra; these 

 punctures are always small and sometimes minute. The outline
