DicHELus EXPANSus, n. spec, 

 Plate XLIL, fig. 24. 



Male : Eesembles D. deiitipes in general build and also in the 

 shape of the hind legs, but it is differentiated by the colour of the 

 body which is black, but has a greenish, metallic tinge, the elytra 

 are redder and opaque, but clothed with the same greyish, appressed 

 pubescence, and the legs are of the same colour as the elytra. 



Female : Like the female of D. dentipes, but it has two distinct 

 denuded patches on each side of the pygidium. 



Although very closely allied to D. dentipes this species is different. 

 It appears also later in the spring.

The description of D. dentipes suits also this species, but the 

 facies is not so robust, the colour of the prothorax is slightly 

 greenish black, that of the elytra varies also from red-brown to 

 fuscous, but instead of having appressed hairs only they have a 

 juxta-sutural band of greyish-white ones not closely set and often 

 partly obliterated ; the pygidium of the female has two denuded 

 lateral patches like the female of D. expansus ; the hind tibiae of 

 the male are sharply carinate underneath and not grooved, but 

 the median inner tooth and the apical mucro are similar to those 

 of the two preceding species.
