which apparently occurs also in Cuba, or the C. coxale (Motschulsky) from Venezuela 

 and the Amazons. 



4. Calosoma viridisulcatum. 



Calosoma viridisulcatum, Chaudoir, Rev. et Mag. Zool. 1863, p. 114 



Hab. Mexico. 



A species unknown to me, and the position of which in the genus is not indicated by 

 its describer. 



5. Calosoma angulatum. (Tab. II. fig. 12.) 



Calosoma angulatum, Chevrolat, Col. Mex. i. fasc. 2 (1834). 



Hab. Mexico, Orizaba, Palo Verde, Tehuantepec (Salle), Esperanza, Plan del Rio 

 (Edge) . 



A closely allied but sufficiently distinct species (C. angulicolle, Chaud.) occurs near 

 Santa Marta, Colombia. 





6. Calosoma peregrinator. (Tab. II. fig. 11.) 



Calosoma peregrinator, Guerin, Rev. Zool. 1844, p. 255 \ 



Hab. Mexico 1 , Guanajuato (Dtiges, coll. Salle), Sierra de S. Miguelito, Valle del Mais 

 (Dr. Palmer), Plan del Rio, Jalapa (Hoge). 



Having been able to examine a large series of this species, including the type speci- 

 men of Guerin, I am able to state with certainty that it is quite distinct from C. promi- 

 nens, Leconte, with which Dr. Leconte himself proposes to unite it. The thorax is 

 relatively to the trunk very much larger and broader, and the elytra much less sculp- 

 tured, the transverse 



small space near the shoulders, instead of extending over the whole basal portion of 



imbricated rugulse of the elytral interstices being confined to a 



Guerin's tvpe these rusrdse are reduced to a minimum 



to a 



elytra. In 



few marginal marks behind the shoulder ; this is the character of all the Jalapa speci- 

 mens, those from Guanajuato having rather more sculpture in the basal and humeral 

 region of the elytra. In general form and outline C. peregrinator resembles more closely 

 the Texan C. lugubre (Leconte) than C. prommens.

7. Calosoma affine. 



Calosoma affine, Chaudoir, Bull. Mosc. 1843, iv. p. 746 l . 



Hab. Mexico 1 . 



Differs from the shorter examples of C. peregrinator only by its more highly polished 

 surface ; some of Mr. Hoge's specimens of the latter, from Plan del Rio, approach it

very nearly in form and sculpture. Chaudoir very aptly compares his species to
