^ Tarsi postici articulo tertio scopulifero. 



* Collum obtuse constrictum. Oculi integri. 



Pachyta, Meg. 

 (P. collariSf L., r.) 



f The species are thus grouped : — 1 . Epimera metathoracica continued 

 beyond the hip; the fore hips distant from each other (C. Bajulus, C. un- 

 datum). 2. Epimera metathoracica not reaching the hind hips : (a) the fore 

 hips close to each other ; the coxal process of the metathorax sharp ( C. 

 Alni, C. violaceum, C. sanguineum, C. variabile) : (5) fore hips separated 

 by a narrow process ; the coxal process of the metathorax broad, with an 

 obtuse point ; elytra thinly covered with very short close-lying hairs ; the 

 flying-hairs of the tibiae rather short ( C. clavipes). 



X This character separates Rhamnusium from the first division of Calli' 

 dium, (See preceding note.)
