CRYPTOGLOSSA. 73 
the ventral segments smoother, the sides and apex only with coarse punctures; mentum very coarsely 
punctured, and with a distinct central groove. 
Length 12 millim. (¢ 9.) 
Hab. Muxtco, Tehuantepec (Sailé). 
Two examples. The thorax in the male of this species is much longer than in the 
female, and the elytra are scarcely twice the length of the thorax; the female is less 
parallel in form, the thorax transverse, and the elytra twice the length of the thorax. 
Group CRYPTOGLOSSIDES. 
This group will contain two closely allied genera (Cryptoglossa and Centrioptera) 
peculiar to the South-western United States and Mexico; another genus (Schizillus) 
occurs a little to the north of our boundary.

Four species are now known of this genus, all of which inhabit Northern Mexico 
and the country adjacent to our northern frontier. 
1. Cryptoglossa bicostata.

Hab. Mexico !. 
I have not seen this species, described by Solier from a single mutilated example. 
2. Cryptoglossa verrucosa.

Cryptoglossa verrucosa, Horn, Rey. Ten. N. A. p. 280°. 
Hab. NortH America, deserts of the river Colorado }, Valley of the river Gila 2.

convex, widened towards the front, the anterior angles very prominent and triangular, the hind angles a
