178 Mr. H. W. Bcates's additions to the 



in Nuevo Leon. It varies remarkably in the form of 

 the thorax, which is either rounded on the sides, or dis- 

 tinctly angulated and even acutely-tuberculated in the 

 middle. This variability exists also in Deltaspis, from 

 which Crossidius is hardly generically distinct. 



Crossidius cegrottis, n. sp. 



Elongatus, postice paullo angustatus, dense pilosus, parum niticlus ; 

 pallida fulvus, elytris flavo-testaceis (interdum sutura postice nigro- 

 fusca marginata), tboracerufo-testaceo, capite, antennis pedibusque 

 nigris. Thorax latus, in medio plus minusve angulatim rotundatus, 

 confluenter puuctatus, disco tricalloso. Elytra basi paullo sparsius 

 postice densius punctata, apice flexuoso-truncato angulis rotvindatis.

We are able now to supply the locality of this species. 

 Mr. H. H. Smith met with it at various places in the 

 State of Guerrero — Dos Arroyos (1000 ft.), R. Papagaio 

 (1200 ft.), Acaguizotla (3500 ft.), Venta de Pelegrino, 

 Tierra Colorada (2000 ft.), Hacienda de la Imagen 

 (4000 ft.). 



The following is a closely-allied but sufficiently dis- 

 tinct species : — 



Ischnocnemis cyaneiis, n. sp. 



Latius cylindi-icus, cj'aneus nitidus, antennis nigris ; capite 

 thoraccquo dense sat grosse sed discrete punctatis, linea niediana 

 postice dilatata Iscvi, elytris aequaliter discrete puuctulatis, utrinque 

 linea longitudinal! nuUo niodo elevata Isevi. Thorax gracile cylin- 

 drico, ovatus. Elytra ad apicem recte trnncata, angulis distinctis. 

 Subtus passim aqualiter minus sparsim punctulatus. Long. 

 13 millim., S • 



Hab. Mexico, Yautcpec in Morelos {Wkje). 



Distinctly broader in form than /. c(erulesccns, the 

 punctuation of the thorax wider apart, the smooth line 

 down the disk of each elytron not in the slightest degree
