ELAODES. 77 
Allowing for some few doubtful species, to be eliminated when those described by the 
older authors are properly identified, Mexico will possess about the same number of 
species as the United States. 
Eleodes is the representative of Blaps in North America, ranging from Hudson's Bay 
and Vancouver Island to the “Los Altos” region of Guatemala; the different species. 
are almost confined to the western side of the continent and to the country west of the 
Rocky Mountains, extending eastward only as far as the Mississippi River. They are 
found beneath stones, &c. in great abundance in the arid regions of California, Arizona, 
New Mexico, Colorado, Texas, and Mexico; species are found from the sea-coast up to 
an elevation. of nearly 11,000 feet. 
In South America Elwodes is replaced by Mycterinus*, an allied genus found in 
Chili. 
1. The basal joints of the anterior tarsi in the male clothed with stout, almost spiny, 
hairs beneath, and scarcely dilated. (E.EoDES, Horn.) 
A. Anterior femora in the male toothed ; in the female bluntly toothed, or emarginate 
near the apex. 
a. Elytra in the male with long caudal appendages, in the female subcaudate. 
1. Eleodes rugosa. 
Eleodes rugosa, Perbosc, Rev. Zool. 1839, p. 263°. 
Eleodes caudata, Sol. Studi Ent. p. 2557. 
Eleodes rugipennis, Chevr. in litt. 
Hab. Mexico 2, Vera Cruz! (Sallé), Jalapa (Hoge). 
Sent in numbers by Hoge. These examples vary in size from 22-31 millim. A 
species with long caudal appendages to the elytra in the male, the upper surface 
coarsely rugulose. 
2. Eleodes eschscholtzi. (Tab. III. fig. 24, ¢.) 
Eleodes eschscholtzi, Sol. Studi Ent. p. 254". 
Hab. Mexico 1, Alamos (Buchan-Hepburn), Presidio (forrer). 
Five examples (four males, one female); the largest male measures 35 millim. 
(including the caudal appendages of 6 millim.). In this species the posterior tibize of 
the male are curved and thin from the base to beyond the middle, and straight and 
thickened towards the apex, a character not mentioned by Solier. 
b. Elytra feebly caudate in both sexes. 
3. Elxodes spinipes. (Tab. IV. fig. 2, ¢.) 
Eleodes spinipes, Sol. Studi Ent. p. 253°. 
Eleodes blaptoides, Dupont in litt. 
* Nycterinus ebeninus, Sol. (Studi Ent. p. 269), is recorded from Mexico; the locality is probably in error 
for Chili.
