It may be observed tbat we have in England a narrow form of 



D. dentata with the sides of the thorax strongly sinuate before the base. 

 It has been found at Plymouth by Mr. Keys and others, and also, I 

 believe, at Sennen, Cornwall. Of the Croydon insect there is a fair 

 series in Mr. P. B. Mason's collection, showing considerable variation 

 in size ; and I have received a specimen agreeing with it from Herr 



E. Reitter from Galicia, under the name D. pygmcea. All these ex- 

 amples diifer from D. Mlirkeli in their smoother surface and much 

 smaller size.
