This species is narrower in form than jjunctatus, and with the basal 

 depressions of the thorax more evident. The color may vary somewhat, 

 a specimen in my cabinet having the elytra distinctly paler than the 

 thorax. 



With this species I have united caloccrus Bonv., the characters given 

 by that author are purely sexual. 



Occurs in the Middle and Southern States. 



T. alicnilS Bonv. — Reddish brown, moderately shining, moderately densely 

 pubescent. Front convex, rather finely not closely punctate. Thorax twice as 

 wide as long, strongly narrowed in front, sides feebly arcuate, disc moderately 

 convex, coarsely and rather closely punctate, a distinct but not deep depression of 

 the base each side of the middle, hind angles acute, moderately prolonged back- 

 ward and extremely finely carinate. Elytra not wider than the thorax, gradually 

 narrower posteriorly, surface striate, stria; distinctly punctured, intervals flat, very 

 regularly biseriately punctate, the punctures finer than those of the stripe, a mod- 

 erately deep depression beneath the Jiumeri parallel with the lateral margin. 

 Prosteruum very nearly smooth, the strife deep, entire and slightly divergent in 

 front. Metasternum and abdomen moderately coarsely and closely punctate. 

 Length .08-.10 inch; 2-2.5 mm. 



A small species resembling some of the smaller forms of Chevrolati. 

 but differing in the form of the eyes. From all our species it differs in 

 the presence of the sub-humeral depression. 



In his monograph this species is described as constrictor by Bonvouloiz. 

 the error was, however, subsequently corrected (Ann. Fr. 18G0, p. 355). 



Occurs in the Gulf States. 



T. Ci»iivei*geiis n. sp. — Oblong, brown, moderately shining, pubescence 

 sparse and rather coarse. Head coarsely sparsely punctate. Front acutely bicari- 

 nate, the carinse converging, and uniting anteriorly at the base of the clypeus, 

 then again diverging to the angles of the clypeus. Thorax nearly twice as wide 

 as long, much narrowed in front, sides feebly arcuate, hind angles slightly pro- 

 longed and finely but distinctly carinate, disc moderately convex, a very feeble 

 depression each side of the middle of the base, surface rather coarsely but not 

 closely punctate, the intervals very finely sparsely punctate. Elytra not wider 

 than the thorax, slightly narrowing toward the apex, surface striate, strise punc- 

 tate, intervals flat with a single series of punctures finer than those of the strise, 

 marginal stria of elytra rather deeper at base. Prosternum with very few punc- 

 tures, the stria} deep, entire and nearly parallel. Metasternum and abdomen 

 coarsely but not closely punctured. Length .10 inch ; 2.5 mm. 



A very distinct species by the emarginate eyes and the strongly cari- 

 nate front, especially in the arrangement of the carinas. 



Occurs in northern Greorgia. 



T. pugnax n. sp. — Oblong, narrower behind, dark brown, moderately shin- 

 ing, rather coarsely pubescent. Head sparsely punctate, front with two rather 

 strong carinte which extend from the occiput to the front margin of the clypeus,
