MB. F. P. PASOOE ON THE CUECULIONIDiE. 77 



lum. Elytra ampliata. Pedes mediocres ; femora breviuscula, 

 mutica ; tibi(e fere rectse, iutus subflexuosse ; tarsi articulis 

 tribus basalibus sensim dilatatis ; unguiculi approximati. Coxm 

 posticse distantes. Processus intercoxalis late truncatus. 



This genus agrees with Dorytomus in tbe absence of ocular 

 lobes, and witli Erirhinus in its mutic femora. I compare it 

 with these two genera as being, in tbis subfamily, the most fami- 

 liar to entomologists. But it is quite distinct from both ; and, like 

 many other genera I have proposed in these " Contributions," it 

 is only as an approximation in aid of the systematist that I ven- 

 ture to do so. In this immense family of Curculionidse there are 

 so many modifications of a common form, which, once seen, is 

 never mistaken for any other, that it becomes almost impos- 

 sible to fix the limits in many instances either of genera or of 

 species ; and their affinities will frequently depend solely on tbe 

 relative degrees of importance that may be attached to certain 

 characters ; and these characters again will have a generic, or 

 even a tribual, importance in some cases, and only an indivi- 

 dual importance in others.
