specimen are, however, entirely black, 36-jointed, slightly 

 incrassated before the apex. Nees states the metathorax 

 to be 4-dentate ; according to Reinhard, and in the 

 British example, it is 2-dentate. Nees says that all the 

 coxfe are rufo-testaceous ; Eeinhard that the hind coxfe 

 are black at the base above ; in the British specimen all 

 the coxae are so coloured. These discrepancies, and the 

 want of more specimens, render the identification mi- 

 certain. The insect agrees, however, very well with 

 Reinhard's description.
