 deT Acad, des Scien. de Turin, is from the coast of Angola. 



SiAGONA, Latr.* Cucujus, galerita, Fab. 



Have a decided emargination on the internal side of the two 

 fore-legs ; the first articulation of the antennae is elongated 

 into a reversed cone, and the second is shorter than the third ; 

 the top of the ligula is straight, without advancing ; the 

 corslet is nearly cup-shaped, nearly as long as it is wide, and 

 without posterior projection, and the labrum is indented. 



Some have the abdomen oval, and Avithout wings ; in others 

 it is oval, truncated at the base, and these species have wings. 

 M. Lefevre has discovered a new one in Sicily. All the rest, 

 as well of this division as of the last, inhabit northern Africa, 

 or the East Indies.f 



The third sub-genus, by its moniliform antennae, the teeth 

 on the outer side of the two fore-legs, the ordinary proportions 

 of the chin, the general form of the body, approach evidently 

 to the Scarites. 



Carenum, Bon. 



The jaws are straight, without a terminal hook. The 

 tongue is round at its summit. The last articulation of the 

 exterior maxillary palpi is swelled out, and is twice the size 

 of the preceding. 



The only known species {Scarites cyaneus, Fab.) inhabits 

 New Holland. 



All other carabici of this section have not the labial palpi 

 terminated by a larger and securiform articulation ; the last 

 is in the form of a reversed and elongated cone, or almost
