and elytra, the latter being more tliickly and finely punc- 

 tured ; also, in the male, by the absence of an}^ distinct ridges 

 on the sixth abdominal segment. 



Taken plentifully by Dr. Power under bark near Thorton 

 Reservoir, Leicester, and stated by Mr. Janson to be also 

 kno\yn to him. Its place is next after G. minima in our lists.

 Determined by Mr. Waterliouse from specimens in his 

 own collection, and in that of Mr. Morris Young. 



This species must come next after Q. peltatus in our lists, 

 from which it differs in being narrower, and uniformly

 bulky, and their punctuation more sparing but much stronger.

 Mr. Waterhouse has pointed out the differences between 

 Q. attenuatus and this species, which has hitherto been con- 

 founded with it in our collections. 



Q. attenuatus, Gyll., is somewhat less robust, the inter- 

 mediate coxos testaceous, the abdomen not striped longitu- 

 dinally, and the elytra jeneous, with dusky pubescence. 



Q. semi-ceneus varies considerably in size, and in the 

 colour both of the elytra and intermediate coxsb ; the larger 

 examples usually have the .most rufous elytra, but the
