certainly referable to this species ; and that the A. violacea of 

 Ent. Heft., to which it has usually been referred, is much 

 smaller and more like A. euj^horbice, Fab.

M. Allard (Mon. des Alt., L'Abeille, 1866, p. 501) notices 

 some British examples of this species which depart from the 

 type form in the punctuation of the thorax being more 

 scattered, and finer on the disc; the rather redder colour 

 of the elytra, of which the suture is brownish; and the rather 

 greater contraction and acumination of the elytra at the 

 extremity. . 



M. Allard, doubting the sufficiency of these characters to 

 establish a species, proposes to add the insects possessing 

 them to the type form as var. Crotchi. 



44. Thyamis castanea, Foud. ; Ent. Ann., 1867, p. 96. 

 Mr. Crotch (1. c, 174) states, on the authority of M. 



AUaid, that our fen " hninnea'' are all referable to this 

 species. He remarks, howevei-, that we have the true 

 T. hrunnea, mixed with T. luriday from whic[i its rounded 

 shoulders at once separate it. It seems, also, to tend to 

 black in colour.
