LeConte.] CRY PTORHY ECHINI. 235 



DIVISION IV. Sp. 23-24. 



This division contains small species of less robust form, easily known 

 by the fine pubescence being mixed with long, stout, erect bristles. The 

 beak is longer than the head and prothorax. not stout, very slightly curved, 

 punctate and striate; antennae inserted one-fourth from the tip; mesos- 

 ternum rather wide, perpendicularly declivous in front. Under surface 

 coarsely, uniformly punctured; thighs armed with one tooth, claws cleft, 

 the tooth being as long as the outer part. Elytra not costate. Front coxoe 

 contiguous as usual. 



Prothorax coarsely cribrate 23. erinaceus. 



punctured 24. hispidus. 



23. C. erinaceus, n. sp. 



Blackish, densely clothed with depressed mud-colored, scaly pubescence, 

 with erect bristles intermixed, which are short on the prothorax, and long 

 on the elytra. Legs, antennae and beak brown; the last named slender, 

 slightly curved, sparsely punctured, feebly striate towards the base. Pro- 

 thorax wider than long, slightly rounded on the sides, moderately nar- 

 rowed in front, and feebly constricted; tolerably densely cribrate. Elytra 

 one-third wider than prothorax, humeri prominent, abruptly rounded, striae 

 composed of large, shallow punctures, interspaces slightly convex. Body 

 beneath shining, sparsely pubescent, coarsely not densely cribrate; last ven- 

 tral segment not impressed. Thighs armed with an obtuse tooth. Length 

 3 mm.; .12 inch. 



Southern States. Judging from MS. drawings made by my father, this 

 ia Calosternus erinaceus Dej. Cat. 318. 



24. C. hispidus, n. sp. 



Of the same form as the preceding but smaller, brown covered with cin- 

 ereous, scaly pubescence; prothorax not wider than long, coarsely punc- 

 tured, with the bristles not shorter than those of the elytra; elytra about 

 one-third wider than the prothorax, rather more elongate than in C. erina- 

 ceus, striate and setose in a similar manner. Body beneath similarly punc- 

 tured, beak, antennae and legs paler brown, femoral tooth smaller and more 

 acute. Length 2.5 mm.; .10 inch. 



One specimen, Georgia. 



MICRALCINUS* n. g. 



A species from Florida which has an almost deceptive resemblance to 

 Tyloderma variegatum, constitutes this genus. It is closely allied to Cono- 

 trachelus, and has the antennal grooves confluent behind in a similar man- 

 ner. The front coxae are also nearly in contact, but the form of body is 

 quite different, the elytra are not suddenly wider than the prothorax, regu- 

 larly oval, and emarginate at base ; the beak is shorter, scarcely longer than 

 the prothorax, and the claws are not toothed. The postocular lobes are as 



*This genus does not appear in the table of genera, as it was overlooked 

 when the form was closed.
