CACCOPHRYASTES.—EUPAGODERES. 93 
margin of the thorax. Elytra slender, the humeri not at all prominent, the strie 
rather fine and bearing somewhat distant, indistinct punctures; they are marked with 
dark lines, and the alternate interstices are slightly paler. One specimen. 
EUPAGODERES. 
Eupagoderes, Horn, Rhynchophora of N. America, p. 32 (1876). 
Ophryastes (part.), Schénherr, Gen. Cure. i. p. 508 (1833). 
I take the existence of a definite patch of adhesive pubescence on each of the lobes 
of the third tarsal joint to bea satisfactory means of distinguishing the species of 
Eupagoderes from Ophryastes. The truncature of the hind tibia is usually more 
perfectly cavernous than it is in Ophryastes. The genus as thus defined is susceptible 
of further division, but this is quite unnecessary at present; the species being com- 
paratively few, though doubtless many more remain to be discovered. 
Eupagoderes is peculiar to the United States and Mexico, and has until now consisted 
of about twelve species, to which I add seven others. The genus seems to be in 
Mexico less exclusively confined to the north than Ophryastes is. 
1. Kupagoderes constrictus, sp.n. (Tab. IV. fig. 7, 3.) 
Pallide griseus, prothorace utrinque vage vittato; elytris ad basin depressis, quasi constrictis, subtiliter 
striatis. 
Long. 73-94 millim. 
Hab. Mexico, San Isidro (Hoge). 
This insect cannot be confounded with any other member of the genus, on account 
of the peculiar neck-like prolongation at the front of the convex elytra, and of the 
more than usually exposed scutellum. There is a feeble depression at the base of the 
rostrum, and on its middle in front are two longitudinal elevations with a short broad 
groove between them. Club of antenne small and stout. Thorax short, greatly 
rounded at. the sides, with rather deep punctures irregularly distributed. The strie 
on the elytra are quite fine, and only very obscurely punctate. 
- Four specimens were found. The female has the elytra very much more ample than 
the male, and the basal constriction considerably shorter. 
2. Hupagoderes speciosus. (Tab. IV. fig. 8.) 
- Ophryastes speciosus, Lec. Proc. Ac. Phil. vi. p. 444°. 
Eupagoderes speciosus, Horn, Rhynch. N. Amer. p. 33”.

Hab. Nort AMERICA, Texas ! 2.—Mexico, Santa Clara in Chihuahua (H6ge). 
We have received only two examples of this remarkable insect. It and the 
following species will, no doubt, be ultimately separated under a distinct genus. In 
E. speciosus the mentum has a very large rugose anterior portion; and the polished 
plane at its base for it to slide over is very large and conspicuous.
