Remarks on the Genus Ceiithorhynchus and Us Allies. 

 By G. R. Crotch, Esq. 



The careful revision and comparison wliich our Curcu- 

 lionidje received at the hands of Mr. Walton are well known; 

 unfortunately, however, his task was never completed, and 

 the large group which at present occupies our atlenlion was 

 never thoroughly investigated. Schonherr himself, it is true, 

 has not entirely avoided confusion in his descriptions of the 

 species of this genus, insomuch that recent careful comparisons 

 of his typical specimens have reduced the European list by 

 no less than thirty-eight species. M. C. Brisout de Barne- 

 ville has during some time occupied himself with this inte- 

 resting group, and is about to publish his work in the en- 

 suing winter, when I hope to furnish a translation of those 

 parts that more especially concern us. In the meantime a 

 fiew preparatory remarks relative to some of our species may 

 not be out of place, as I have been fortunately able, through 

 the liberality of Dr. Power, to lay a nearly complete series of 

 our English species before him. The genus, or, as it is more 

 fairly regarded, sub-genus, Ceuthorhynchidius, J. Duv., — 

 distinguished by having only six joints to the funiculus, — 

 is well represented in this country. It has, hovvever, very 

 generally escaped notice that C. Troglodytes, F.^ and C. hor- 

 ridus, F., belong to this section, as well as C. floralis and its 

 allies. No alteration in our nomenclature is here called for, 

 except that the C. Poweri, Rt/e (Ent. Mo. Mag. i. 137), is 

 identical with C. pumilio, Gijll.^ Silih., which is of course 

 the older name. De Marseul has placed this species cor- 

 rectly in this sub-genus, in the second edition of his 'Cata- 

 logue ;' but I cannot find that anyone else has noticed it. 

 A specimen from Dr. Power's collection, near C. floralis, but 

 distinct, has been returned as C. hepaticus, Sclih. Descrip- 

 tions of this and some other new species will appear with the
