618 DR. R. CG. L. PERKINS ON THE 
I have seen only two males of this species, differing greatly in 
colour, as above described. The antenne are 11-jointed, the 
three apical ones very minute, and difficult to see in my speci- 
mens, being sunk in the apical cavity of the eighth joint.

With this species begins a small series of forms, distinguished 
at once from any of the preceding by the sculpture of the tegule, 
which are either densely minutely punctured over nearly all their 
surface or bear coarse and conspicuous punctures, with evident 
fine ones between these, towards the outer margin on the anterior 
part.
