CLERUS. | 161 
thorax is denuded, the suture and base of the elytra partly so. Basal and second joints 
of the antenne red beneath ; palpi pitchy, black at the tips. The first fascia singularly 
angulated, like the letter A with its apex towards the base of each wing-case; the 
transverse fascia does not quite touch the suture or margin, so that the enclosed black 
triangle is connected with the apical part, which is leaden. 
I possess a specimen from the collection of my late friend W. W. Saunders, Esq. ; 
and there are two in Sallé’s collection from Peras.

The Puebla specimens, two in number, have the breast a little infuscate, but the legs 
red, except the tarsi. A single specimen from Huanchinango has the breast red; it 
is only, however, the size of the other specimens. My specimen from Dr. Baden is the 
only one I have seen with entirely black legs and breast. I do not now think it will 
prove distinct.

I have not been able to identify this insect; and it seems difficult to interpret the 
diagnosis which I quote as to the colour of the thorax. It was unknown to Spinola.

A very large series of specimens have now been sent of this species, showing that it 
is subject to a good deal cf variation. In a few from Zapote, Las Mercedes, and Cerro 
Zunil the head is red; in some the black at the base is divided, forming two subhumeral
