5 (a). Chalepus bivittaticollis. 
Sat elongatus, niger, subtus nitidus, supra subnitidus ; thorace subconico, disco crebre punctato, utrinque vitta 
submarginali callosa impunctata fulva instructo; elytris parallelis, ad suturam late subquadrato-emar- 
ginatis, utrisque octo-, basi extrema nono-seriato-punctatis, interspatio secundo nec non sutura costatis ; 
interspatiis tertio ad sextum subelevatis. 
Long. 3 lin. 
Hab. MEXxico, Parada, Oaxaca (Sallé). 
Front trisulcate; antenne filiform, the four upper joints closely articulated, the 
sutural lines only visible under a lens. Thorax transverse; sides converging from base 
to apex, more quickly so before their middle; upper surface transversely convex, 
transversely excavated posteriorly, coarsely and strongly punctured; on either side, 
within the lateral margin, is a broad, callose, impunctate, fulvous vitta. Elytra parallel ; 
sides serrulate, rather more coarsely so towards the apex; apical margin distinctly 
dilated, broadly subquadrate-emarginate at the sutural angle; each elytron with eight, 
at the extreme base with nine, rows of deeply impressed punctures; the second inter- 
space, together with the suture, costate; the third to the sixth interspaces slightly but 
distinctly elevated. | 
Very similar in form to C. morio, but the short additional basal row of punctures, 
together with the sublateral fulvous thoracic vitte, will at once distinguish it from that 
~ species.
