482 CLASS TNSECTA. 



But few species are known, and all belonging to Brazil.* 



AiiEODEs, Leach, Macl. 

 Have ten articulations to the antennas, the sternum horny, 

 and all the hooks of the tarsi equal in those individuals 

 which are presumed to be females (Lepel. and Serv.), and 

 unequal in the males ; the thickest of the anterior two of the 

 latter is bifid, and all the others are entire. 



These insects have brilliant colours. 



All the preceding phyllophagi, some excepted, have pre- 

 sented us with antennee of ten articulations. In all the fol- 

 lowing, and of the same division, or that of Melolonthidae, 

 we reckon but nine. 



In some the crooks of the tarsi are equal ; one of the two 

 anterior at most is occasionally thicker. 



Dasyus, Lepel. and Serv., 



In which the crotchets of the two anterior tarsi, at least in 

 the males, are bifid, and the others entire, 



Serica, Macl. Omalopia, Dej., 



Which have all the hooks of the tarsi bifid, the body ovoid, 

 gibbous (silky, and often with a changing reflexion), with the 

 corslet broader than long.-j- 



DlPHUCEPHALA, Dej. 



Have also all the hooks of the tarsi bifid ; but the body is 



* The ceraspis pruinosa of MM. Lepel and Serv. (Encyc. Method.) is 

 the M. bivulnerata of M. Germar. The M. variegata of the latter appears 

 to me to be also a Ceraspis.

 ruricola. Sec. of Fabricius. Mr. Macleay says that the antennas have ten 

 articulations, but I have counted but nine. The length and form of those 

 of the tarsi vary.
