ORDER COLEOPTERA. 559 



Tenebuio, 



Such as Fabricius liad at first formed it, and to which we 

 shall re-attach that which he names Opatrum, and that of 

 Orthocera. They will serve as types to so many particular 

 divisions. 



1st. — Those whose body is oval, with the corslet almost 

 trapezoid, arched laterally, or in a truncated demi-oval an- 

 teriorly, wider at least at the posterior edge than the abdo- 

 men, but little or not at all edged out ; the maxillary palpi 

 terminated by a hatchet-formed articulation, or some form 

 very analogous, and the antennae thickening insensibly. 



Crypticus, Latr. Blaps, Fab., 



Have the body convex and smooth above, with the head un- 

 covered, or but little sunk in the emargination of the corslet, 

 without emargination at its anterior edge ; the eyes external, 

 or altogether outside of the anterior concavity of the corslet, 

 and this last part of the body insensibly inclined in the sides, 

 and but little emarginated in front. The antennae are almost 

 of its length, with most of the articulations in the form of a 

 reversed heart or top, the penult alone being more rounded, 

 or almost grained, but not transverse. The legs are always 

 narrow and elongated, with the terminal spurs tolerably pro- 

 jecting.* 



Opatrum, Fab. Dej. Phylum, Meg. 



Their body is generally less raised, and even often de- 

 pressed. The head is received posteriorly, with the eyes in 

 a deep emargination of the corslet, and its anterior edge pre-
