122 ENDOMYCHIDJL 



5. Epipocus mutilatus. 



Epipocus mutilatus, Gerst. Monogr. Endom. p. 24§ l . 



Hab. North America, Texas ^Mexico, Vera Crttz * ; Guatemala, Capetill 

 (Rodriguez), Zapote, San Juan and Teleman in Vera Paz (Champion). 



A difficult species to determine : the punctuation seems closer, and hence the whole 

 insect is duller than its allies ; the thorax is marked as in E. ductus. The difficulty 

 arises from the fact that Gerstacker has described the species from female specimens 

 only, in which sex the apex of the elytra is usually more straightly cut off than in the 

 males. The colour of the abdomen is variable and of little Value as a specific character. 

 An example from Capetillo which I refer doubtfully to this species is a male ; and I am 

 inclined to think that E. cinctus, Lee, and E. mutilatus, Gerst., represent one and the 

 same species. 



b. Apex of the elytra simple, founded. 



6. Epipocus tibialis. 



Endomichus tibialis, Chevr. Col. Mex, Cent. i. fasc. 4 (1834) 1 . 



Endomychus {Epipocus) tibialis, Chevr. Icon. Kegne anim. p. 317, t. 50. f. 9 2 . 



Epipocus tibialis, Gerst. Monogr. Endom. p. 251 3 . 



Hab. Mexico 2 3 , Orizaba (Lesueuf x ), Jalapa (Hbge), Cordova, Toxpam, San Andres 

 Tuxtla, Playa Vicente (Salle), Teapa in Tabasco (H* H. Smith) ; British Honduras, 

 E. Sarstoon (Blancaneaux) ; Guatemala, Las Mercedes, Zapote, Capetillo, San Geronimo, 

 Sabo, Teleman, Chiacam, Senahu, San Juan in Vera Paz (Champion), Coban (Conradt). 



This insect is very abundant in some places, as at Jalapa. Certain specimens from 

 Zapote, Teleman, &c, have the abdomen entirely yellow, but in other respects so 

 entirely agree with typical examples that I cannot regard them as distinct. 



7. Epipocus bivittatus. (Tab. VII. fig. 12, & .) 



Epipocus bivittatus, Gerst. Monogr. Endom. p. 253 1 ; Crotch, Trans. Am. Ent. Soc. 1873, p. 361 2 . 

 Eab. North America, Tennessee 1 , South Carolina 2 . — Mexico, Villa Lerdo in 

 Durango, Jalapa (Edge), Cordova (SalU), Temax in North Yucatan (Caumer). 



The identification of our insect with this species, which was only known to Gersticker 

 by a single female example from Tennessee, is made with some hesitation ; but the 

 examples received agree more nearly with the description than with that of Epipocus 

 punctatus, the chief discrepancy between our species and E. bivittatus, to which, 

 however, I do not attach much importance, being that usually only the two basal joints 

 of the antennae and the apical one are red. It is also rather larger than one would 

 expect, being from six to seven millimetres in length. A male example from Jalapa is
