AMERICAN COLEOPTERA. 285 



broadly margined as Brachypeplus. Following Murray, Carpophilus 

 and Colastus are separated, but from the observation of material at 

 my command these should be closely approximated at one end of a 

 generic series, while Cillseus, Brachypeplus and Gonotelus are in the 

 other extreme. In fact Murray's " transition genera" show how little 

 dependance can be placed on his two divisions above named. 

 We have but one species in our fauna. 



B. glaber Lee— Elongate, parallel, much depressed, reddish-brown, sur- 

 face glabrous, abdomen piceous. Head moderately densely punctured. An- 

 tennae rufous, club darker. Thorax quadrate, about a third wider than long, 

 apex very feebly emarginate, base truncate, sides straight, very slightly arcu- 

 ate in front, margin narrowly explanate posteriorly, hind angles rectangular, 

 disc feebly convex, surface moderately coarsely but not densely punctured. 

 Elytra a little longer than wide conjointly, surface striate, strife indistinctly 

 punctured, intervals flat with a series of moderately closely placed punctures. 

 Abdomen above more finely»punctured than the thorax, beneath more coarsely 

 punctured than above. Length .12 inch; 3 mm. (PL III, fig. 28). 



This species belongs to Murray's division Liopepbis, and more 

 closely allied to ruhidus than any other. The other species of this 

 group are known only from western Africa. 



Collected by Hubbard and Schwarz, at Enterprise, Florida ; ex- 

 tremely rare. 



COarOTEIiUS Erichs. 



Labrum short, transverse, feebly emarginate. Antennse terminated 

 by a three-jointed club of rounded or oval form, flattened ; grooves 

 slightly convergent passing backward toward the posterior border of 

 the head. Abdomen elongated, three joints exposed above, beneath 

 first two short and equal, third and fourth of equal length each as 

 long as the first two together, fifth elongate, flattened conical, longer 

 than the preceding two together. Tarsi dilated. 



The males have the terminal dorsaL segment truncate and feebly 

 emarginate with a small additional segment exposed. 



TJie species of Gonotelus have an elongate form and resemble Staphy- 

 linidse, recalling Trogophloeus. They divide themselves into two series 

 according as the abdomen is margined or not, the character being 

 really parallel with that existing in Sfenus. 



Our species are as follows : 



Abdomen acutely margined. Head slightly prolonged behind the eyes. 



Sides of thorax posteriorly sinuate, (PI. Ill, fig. 11) Steuoides. 



Abdomen not margined. Sides of thorax feebly arcuate. Eyes large occupy- 

 ing the entire side of the head. (PL III, fig. 10). 



Legs testaceous obscurns. 



Legs piceous black mexicanus.
