valde transverso, postice fortiter sinuato-angustato, angiitis posticis acutis, punctato, disco laevi ; elytris 

 vitta sutnrali politissima, stria suturali obsoleta, yitta laterali latiore, opaca, striato-*punctata, unifoveolata, 

 striis vix impressis sequaliter inter se approximatis, punctis interdum obsoletis, interstitiis transversim 

 multiimpressis. 

 Long. 2 lin. 



Hab. Mexico, Las Vigas (Hoge) ; Guatemala, San Geronimo (Champion). 



The first (inner) elytral stria is obsolete, except near the base ; but it reappears as a 

 very faint curved line near the apex, where it nearly joins the sutural stria. The 

 species is allied to N. semiopacus (Eschsch.), but is larger, differently sculptured on the 

 forehead and along the opake vitta of the elytra.

CALOSOMA. 



Calosoma, Weber, Obs. Entom. i. p. 20 (1801) ; Fabr. Syst. El. i. p. 211 (1801). 



Upwards of 100 species of this almost universally distributed and conspicuous g 

 have been described. A large proportion of these are peculiar to 



Mexico : but the 



seems extremely rare in the countries of Central America further south 



1. Calosoma scrutator. 



Carabus scrutator, Fabr. Ent. Syst. i. p. 149; Oliv. Ent. no. 35, p. 41, t. 3. f. 32a, b. 



Hab. Mexico, Toxpam (Salle), Playa Vicente (Hbge).— North America. 



A large series of this beautiful species, taken by Herr Hoge, differ in no essential 

 particular from specimens found in the Eastern United States. 



2. Calosoma aurocinctum. (Tab. II. fig. 10.)

 Calosoma splendidum, Perbosc, Rev. Zool. 1839, p. 261 (nom. prseoec.) 



Hab. Mexico, Campeche (Salle), Yucatan (Boueard).

Hab. Mexico \ Toxpam, Cordova, Chiapas (Salle), Jalapa, Plan del Rio (Hoge). 



West Indies, Jamaica. 



Leconte considers this species to be the alternans of Fabr., described as from the 

 West-Indian Islands. But the description of Fabricius, " striis (interstitiis) alternis

latioribus," does not at all fit the Mexican and Jamaican insect, in which striae and 



interstices are of uniform width, and suits better an allied species from Venezuela,
