Hab. North America, Vancouver’s Island ?.—Mexico%, Chalchicomula (Sai/é), 
Guanajuato (Dugeés, coll. Sallé). 
I have no hesitation in uniting the species cited above. A specimen of C. sphegeus 
from Vancouver’s Island, in my own collection, only differs from Mexican specimens of 
C. arachnodes in being rather larger and in having the legs black; in C. arachnodes 
they are reddish at the base. It appears a rare species: there are three specimens 
in the Sallé collection from San Andres (Chalchicomula), and one from Guanajuato, 
which is quite denuded, or lacks the pale fascia of ashy hairs. 
7. Clerus viduus.

In fine examples the elytra are clothed with a fine ashy pubescence, with two denuded 
spots on each; but in rubbed ones these quite disappear. ‘The legs, metasternum, and 
abdomen are red, the tarsi darker. Rare.
