AMERICAN COLEOPTERA. 257 



small elevated tubercle, or little horn. Since this insect occurs wherever S. 

 surinaniensia is found, it may be only a variety of the latter, though much less 

 common. Both forms occur in either sex, the males being distinguished in both 

 species by the toothed hind thighs. 



Lathropus vernalis Zim. — [This name is given to the species mentioned by 

 me, Proc. Acad. Nat. Sc. Phila. 1866, 379, but the characters by which it is to 

 be distinguished from the European L. sepicola are not pointed out. Compari- 

 son of specimens is therefore still necessary.] 



Nausibius major Zim. — Length 2— 2J lines. Of the same form as N. denta- 

 tus, but somewhat larger, of black color, with reddish-brown antennse and legs, 

 and perceptibly more coarsely punctured. — Carolina. This species is found only 

 Tinder the bark of old oaks. 



LaemopWoeus testaceus. ^Cuckjms test. Fabr. &c. — Europe and North America. 

 [Not before noted as common to the two continents; I described it as L. Zim- 

 mermanni.] 



Laemophloeus pusillus.= Cwcit/us pus. Schcenherr.=C minutxts Oliv. — Europe, 

 Africa, North and South America. [Not before noted as occurring in the United 

 States.] 



Laemophloeus alternans Er. — Europe and North America. [Not before ob- 

 served in the United States ; neither of these species were in my collection.] 



Cryptophagus crooeus Zim. — Length 1 — U line. Ferruginous, coarsely punc- 

 tured, clothed with long hair, moderately broad and convex. Prothorax with 

 the lateral teeth directed more upwards than outwards, therefore appearing less 

 prominent than they really are; the outer surface of the front tooth highly 

 polished, convex and circular; elytra with punctures arranged in rows; anten- 

 nal club unusually thick. — South Carolina. 



Cryptophagus crinitus Zim. — Length 1 — li line. Ferruginous, thickly, tol- 

 erably strongly punctured, punctures placed without order, pubescence short. 

 On the prothorax only the two front elevations are visible, the side margin is 

 narrowly reflexed and the lateral teeth are very obtuse, the front tooth has a 

 highly polished rounded surface which is impressed in the centre. Elytra with 

 two fine stritti each side of the suture, which are abbreviated in front; anten- 

 nal club unusually thick. — South Carolina [and Illinois.] 



Cryptophagus fungicola Zimm. — Length 1 line. Ferruginous, finely and 

 thickly punctured, clothed with prostrate gray. hairs; marginal teeth of the 

 prothorax scarcely visible, and the polished spots of the front angle very nar- 

 row; the four elevations and the little fold at the base are quite evident: an- 

 tennal club small. — Carolina. 



[This and the two preceding species belong to the division of the 

 genus in which the prothorax has more or less evident smooth eleva- 

 tions, and a very short elevated ridge at the middle of the base; in 

 the next species no such inequalities of the surface are apparent, and 

 the disc is regularly convex.] 



Cryptophagus nodulangulus Zim. — Length 1 line. Ferruginous, very shin- 

 iug, finely and equally but not closely punctured, clothed with prostrate yellow- 

 hair; prothorax altogether evenly convex, distinctly bidentate on the sides, the 

 front tooth not planed down, but convexly protuberant. — Middle and Southern 

 States.
