122 HETEROMERA. 
punctured. Beneath reddish brown, shining, very sparingly and finely, the sides more closely, punctured ; 
prosternum slightly rounded at the apex, margined within; legs and antenne red or reddish brown. 
Length 73 millim. 
Hab. British Honpuras, Rio Hondo, Belize (Blancaneaux) ; GUATEMALA, Cubilguitz 
(Champion).—Co.oms1a (coll. F. Bates, ex Laferté coll.). 
Several examples. Smaller, narrower, and more shining than R. sulcatulus; the 
sides of the thorax straight, the elytra differently sculptured, and the tarsi shorter. 
EUPSOPHUS. 
Eupsophus, Horn, Rev. Ten. N. A. p. 347 (1870) ; Lec. & Horn, Class. Col. N. A. p. 878 (1888). 
A single species of this genus has been recorded from California; we now add 
another from Mexico. 
Eupsophus is placed by Dr. Horn (Joc. cit.) at the end of the group “ Tenebrionides,” 
with the remark that it should probably constitute a separate tribe and be placed 
near the “‘ Goniaderides” of South America. 
In general form this genus resembles certain species of Himatismus or Epitraqus. 
1. Eupsophus horni. 
Eupsophus horni, F. Bates, in litt. 
Allied to E. castaneus, and differing as follows :—Dull dark castaneous ; the head very closely and rugulosely, 
the epistoma a little less closely but rather more coarsely, punctured; prothorax finely, closely, and 
confluently punctured; elytra irregularly and closely punctured, but not so closely as the head and 
prothorax, the punctures separate, the interspaces feebly or indistinctly wrinkled, and with traces of obsolete 
shallow longitudinal grooves. Beneath slightly shining, finely and rather closely punctured. 
Length 103 millim. 
Hab. Mexico (coll. F. Bates). 
Two examples. . horni may be readily separated from E. castaneus, judging from 
the description, by the very close and uniform punctuation of the dull upper 
surface. 
Group PEDINIDES. 
This group will include a few genera, all but one of which are found in North 
America. With the exception of Hopatrinus, the eyes are, in our genera, completely 
divided. One genus (Blapstinus) is represented by many species, the remainder by 
one or two species only. Mecysmus, a genus found at Fort Yuma in California, and 
near our northern boundary, has not yet been received from our country. 
Other allied genera, Diastolinus and Cenophorus*, are found in the Antilles. 
* Single examples of Diastolinus puncticollis, Muls., and D. costipenms, Muls., and of Cenophorus viduus, 
Muls., labelled “‘Mex.,” are contained in Mr. F. Bates’s collection ; it is possible there is some mistake about this 
locality, as these species were all described from the island of Santo Domingo. Diastolinus is, however, known 
from the north-east coast of South America; the genus may occur also on the Atlantic side of Central America.
