vialltis, Pdchymcrola, Triacctclus, and Axestolcus) are 

 characterized as new. 



Of the five linown species not previously recorded from 

 Mexico or Central America, two are North American, one 

 is South American, one Cuban, and one of general dis- 

 tribution. The well-known boreal genus Asemum has 

 now a recorded representative from as far south as the 

 Mexican State of Guerrero. 



The material for this paper has been accumulating 

 since January, 1886, when vol. v. of the Coleo[)tera of 

 the ' Biologia Centrali-Americana ' was completed. It 

 has been chiefly obtained by the following collectors : — 

 (1), Herr Hoge, during his Second Mexican Expedition ; 

 (2), Mr. H. H. Smith, in Mexico, chiefly in the States of 

 Guerrero, Yera Cruz, and Tabasco ; (3), Mr. Gaumer, in 

 Northern Yucatan ; (4), Mr. Baron, in the Mexican 

 State of Guerrero, kindly communicated by Mr. Harford ; 

 (5), Mr. Becker, in the Mexican State of Durango ; ((5), 

 Mr. Flohr, in Mexico ; (7), Herr Conradt, in Guatemala ; 

 (8), Herr E. Trotsch, in Chiriqui.— F. D. G.]

 to the Mexican fauna.

This distinct species can be compared only with D. 

 lon'iicornis. It has the same elongate, somewhat narrow 

 and parallelograramical form of the body, and very 

 similar elongated antcmicO. It differs, however, from 

 all the numerous examples of /). lonf/icorttis which I 

 have seen in the minutely granulate-coriaceous surface
