I have ventured to differ from M. Lacordaire in raising the 

 Chlamydce from the rank of a sub-family of the Clythridae to that 

 of a separate family. These insects appear to me to occupy a 

 place midway between the true Clylhridce and the Cryptocephalidce , 

 presenting strong affinities with either group. 



Agreeing with the former principally in the form of the antennae, 

 with the latter in the presence of a prosternum and in the entirely 

 exposed pygidium, they differ from either in possessing prothoracic 

 grooves for the reception of the antennae, being allied by this 

 last character to the Lamprosomidce. The other sub-families of 

 Lacordaire's family Clythrldce, with which, however, I have not 

 to deal in the present work, ought also, in my opinion, to form 

 separate families. 



In support of the above view I may mention that M. Lacor- 

 daire himself, in his Introduction, places the genus Chlamys 

 amongst the Cryptocephalidce, whilst in the body of the work 

 he makes it a sub-family of the Clylhridce, showing clearly the 

 difficulty he had in determining to which of the two groups it was 

 most closely allied. 



I have not given a definition of the family Chlamydce, it being 

 sufficient to refer to the characters of the Chlamydece, as laid 

 down by Lacordaire.
