COLEOPTERA. 565 



posed of eleven joints(l), terminate in a club formed by the 

 three last, which is compressed and in the form of a reversed 

 cone or triangle. The first joint of the tarsi is always very 

 distinct ; the penultimate is usually bilobate, and the last, 

 which presents a knot at base, is always terminated by two 

 hooks. The elytra entirely cover the abdomen and are not 

 truncated. The last of the Trim era, or those of the third 

 family, in this character, as well as in several others, approxi- 

 mate to thePentamerousBrachelytra, and some other Coleop- 

 tera of the same section, such as the Mastigi and Scydmseni ; 

 their habits are also very different from those of the other 

 Trim era. 



FAMILY I. 

 FUNGICOLyE. 



In our first family of this section we observe antennae longer 

 than the head and thorax united, an oval body, and a trape- 

 zoidal thorax. The maxillary palpi are filiform or a little 

 thicker at the end, but are terminated by a very large and 

 securiform joint. The penultimate joint of the tarsi is always 

 deeply bilobate. 



This family may be reduced to one great genus. 



Eumorphus. 



In some the third joint of the antennae is much longer than the 

 preceding and following ones. Such are 



Eumorphus, Web. Fab. 



Or the Eumorphi proper, where the club of the antennae is abrupt, 

 compact, strongly compressed, and in the form of a reversed trian- 

 gle. The maxillary palpi are filiform, and the two last joints of the 

 labials united form a triangular club. 



They are all peculiar to America and the East Indies(2). 



(1) In Clypeaster I counted but nine; the Insects, however, are so small that 

 there may have been some mistake.
