as follows ; on the head three vitt;e and a sprinkling over the 

 whole surface, on the pi-othorax four wide irregular and interrupted 

 vitt.T, on the elytra small patches in the striie (liere and there 

 dilating on to the interstices) wldcli give the appearance of 

 numerous conspicuous golden j'ellow spots. The ring of pallid 

 (scarcely golden) scales round the femora near tlieir apex — it is 

 interrupted on the inner face of the femora- -is also a conspicuous 

 character. 1 have, however, seen a single example in which the 

 golden scales are nearly w-aiiting (probably through abrasion), and 

 this one is of an almost uniform deep opaque black colour. This 

 species differs from the two previously described of the genii a 

 inter alia by the second joint of the funiculus slightly longer 

 than the first joint.

This species differs from all the I'olijphrades known to me by 



the structure of its claws, which, to a casual glance, appear to be 



limited to a single claw on each tarsus, and this appears to be 



dentate near its base ; but on careful examination this dentate 



appearance is seen to be caused by the presence of a very short 



second claw closely soldered to its fellow, except at its extreme 



apex, whiclv projects as a minute tooth-like point. A further very
