Mr. Crotch, near London ; M. Bedel appears to make no allusion to 

 it, and I should be inclined to regard it as merely a form, and not a 

 separate species. 



G. viridipennis, Bris., which has been included in our catalogues, 

 appears now to be dropped ; it was said to come near G. chalybceus. 

 Dr. Sharp omitted it from the second edition of his catalogue, and 

 M. Bedel does not refer to it. 



C. quercicola, Bris., and G. versicolor, Bris., which are given as 

 separate species in the last European catalogue of Heyden, Beitter, 

 and Weise, cannot be regarded as distinct ; and G. Crotchi, which is 

 also separated in the same catalogue, appears to be merely a variety 

 of G. quercicola, with the thorax somewhat more depressed, and the 

 tarsi testaceous, and furnished with smaller claws. 



C. Chevrolati, Bris. (minimus, Walker,?), is not mentioned by M. 

 Bedel ; I have a specimen given me by Dr. Power, which at first sight 

 seems very distinct from G. troglodytes, of which it has been regarded 

 as a variety ; it is, however, smaller, and the pubescence is quite 

 different, although structurally it much resembles the last named 

 species. 



G. nigroterminatus, "Woll., appears to be probably identical with 

 G. mixtus, Mulsant and Bey, although M. Bedel regards the synonymy 

 as somewhat doubtful. 



With regard to the classification of the tribe Ceuthorrhyncina, 

 M. Bedel makes a radical alteration, as he includes all the usually 

 received genera under three, Amalus, Mononychus, and Ceuthorrhynchus , 

 which he separates as follows : — 



I. Presternum at least as long before the anterior coxse as the coxa itself, and deeply 



incised at throat. 



i. Onychium terminated by a single claw ; scape half as long as the 



funiculus Mononychus. 



ii. Onychium terminated by two claws (simple, dentate, or appendiculate) ; 



scape usually as long as the funiculus Ceuthorrhynchus. 



II. Presternum reduced before the anterior coxa? to a narrow border, and truncate 



or broadly emarginate in an arc on its anterior margin Amalus. 



Of these genera, Mononychus stands by itself ; Ceuthorrhynchus 

 includes Gceliodes, Poophagus, Ceuthorrhynchus, Ceuthorrhynchidius, 

 Tapinotus, and Hhytidosomus ; and Amalus comprises Phinoncus, 

 Amalus, Eubrychius, Litodactylus, and Phytobius. I am strongly in- 

 clined to follow M. Bedel in this arrangement, but am somewhat 

 doubtful as to the true position of Amalus proper, containing the two
