AMERICAN COLEOPTERA. 253 



four exterior dorsal striae of the elytra entire, the two inner ones abbreviated 

 in front; the inner lateral stria only rudimental, or entirely absent. I fiiund 

 this European species also in South Carolina. [Not before noted as occurring in 

 America.] 



Carcinops lautus Zim. — Long. | line. Oval, convex, very shining piceous, 

 antennse and legs ferruginous; head and prothorax finely sparsely punctured, 

 punctures of different sizes ; marginal stria of prothorax very fine, scarcely obv 

 vious in front; elytra with the sutural stria feeble, composed only of separate 

 punctures, and abbreviated in front, five dorsal striae entire, slightly curved in- 

 wards, and distinctly punctured; the inner lateral stria is well developed, and 

 finer than the dorsal striae; pygidium and propygidium smooth; mesosternum 

 deeply emarginate in front, and surrounded by a fine stria; front tibiee 2-tooth- 

 ed. — North Carolina. 



Carcinops troglodytes Mars. — [Under this name he notes the species which 

 is not uncommon in the Southern States, and which is usually regarded as Par- 

 omalus pumiiio Er.] 



EcHiNODES Zim. — An intermediate form between Eretmotus and 

 Hetserius, and easily distinguished from the latter by the large, long, 

 broad, and concave mental lobe, (Kinnlappen). 



E.S0tiger.=-Hete?-n«.S5e<i5'er Lee. Proc. Acad. Nat. Sc. Phil. 1859, .316. — I found 

 this insect on April 13th, in the nest of a small brown ant at Columbia, S. Caro- 

 lina. 



Paciiylopus Er. — These insects differ from Snj^rimt'S by their 

 incrassated thighs, and by the club shaped, thickened middle and hind 

 tibiae being densely clothed with spines. In the form of the head they 

 agree with the first division of Saprmiis ; the prothorax is large and 

 smooth, or at least only punctured along the hind-margin. 



The following divisions may be established : 



A. Upper surface smooth : 



a. Presternum forming a strong acute keel. — (P. dispar, Africa.) 



B. Upper surface punctured : 



b. Presternum strongly carinate, margined only near the base, which is 



broader. — (P. suldfrons, scrrulatus.) 



c. Prosternal striae equally apparent at the base, but converging at the mid- 



dle into a longitudinal line. — {P. palmatus.) 



d. Prosternal striae closely approximate, but separate to the apex. — (P. 



dimidiatv.s of Europe). 



Epierus novellus Zim. — Long. 1 line. Smaller and narrower, and more par- 

 allel in form than nigrdlus, piceous, with ferruginous antennae and legs, very 

 finely and thickly punctured, somewhat more coarsely upon the prothorax than 

 the elytra ; the striae entire, fine but well impressed, and also regularly curved ; 

 the two inferior marginal striae feeble and slightly punctured; pygidium flat, 

 and like the propygidium, thickly aud strongly punctured. — Carolina. 



Epierus planulus Er. — Columbia, Mexico, California. LeConte has discribed 

 (Ann. Lye. Nat. Hist. New York, V, 164) this species under the name decipien.1. 

 The order of names given in his List, p. 28, is incorrect. [By a typographical 

 error the synonym decipiens has been placed ofter vicinus Lee. instead of planu- 

 lus Er.j
