112 LAMELLICOENIA. 



$ . Vertex transversim carinulatus, carina breviter trituberculata ; thorax medio antice carina acuta leviter 



biarcuata. 

 Long. 7-9 millim. tf $ . 



Hab. Mexico, Cordova, Toxpam, Playa Vicente {Salle), Colima city {Edge) ; Nica- 

 ragua, Chontales (Belt, Janson). 



Possibly not distinct from the Colombian B. modestus, Casteln. ; but the describer 

 makes no mention of the arcuated or semicircular clypeus, the fine anterior margin of 

 which is conterminous or nearly so with the edge of the epistome. His description is 

 taken from the female, and the sculpture of the fore part of the head and elytra applies 

 fairly well to the female of the present species, with the exception of the " corselet 

 crible de gros points " and the impressed dorsal line. 



We figure a male example from Chontales. 



GEOTRUPES. 



Geotrupes, Latreille, Precis des caract. gen. des Ins. p. 6 (1796) ; Erichson, Ins. Deutschl. iii. 1, 

 p. 723 ; Jekel, Ann. Soc. Ent. Pr. 1865, p. 513 ; Horn, Trans. Am. Ent. Soc. 1880, p. 145. 



More than a hundred species are known of this familiar genus, so eminently charac- 

 teristic of the Insect Faunas of the north temperate zone of both hemispheres. It passes 

 into the northern tropical zone both in America and in Eastern Asia ; but it is doubtful 

 if it is found so far south as Celebes, as recorded in the distribution of certain Japanese 

 species. The locality "Peru" found by M. Jekel to be attached to specimens in Mr. 

 Saunders's collection appears to have been erroneous, the insects being Mexican ; and 

 a species (67. lateridens) recorded as from Chili proves to be European (G. subarmatus).

Hab. Mexico \ Juquila (Salle). 



The typical specimen in the Salle collection, a male of minor development, differs 

 much in the form of the thorax from corresponding individuals of G. fronticornis : 

 this part is very much broader, chiefly owing to the explanated lateral margins ; 

 from the subangular dilatation in the middle it is greatly narrowed nearly in a straight 

 line to the anterior angles, and less, but still considerably, narrowed to the hind angles.
