It seems desirable to say a word regarding the sexual characters 

 of Phyllotomis, which to some extent vary with the species. In 

 all of them the male has one of the claws of its front tarsi more 

 or less (in some species very much more than in others) dilated. 

 There is also a tendency towards darker coloring in the males 

 than in the females of some species, and in several species the 

 elytra of the female are much more hairy than those of the 

 male. This latter character is very noticeable in P. australis, 

 Boisd.; but is extremely developed in P. Kingi, Macl., the female 

 of which has its elytra densely set with velvety pile while in the 

 male the elytra are nearly glabrous on the disc. Sir W. Macleay 

 is certainly justified, I think, in regarding Lacordaire as in error 

 when he finds sexual characters in the antennae of Phyllotocus. I 

 do not observe any sexual differences in the armature of the 

 front tibiae.
