Co lasp is din lidiata. 



C. oblongo-ovata, convexa, pallide fulva, nitida ; abdomine elytrorumque 

 dimidio postico nigris. — Long. 4-5 lin. 



Oblong-ovate, convex, pale shining fulvous ; abdomen and the pos- 

 terior half of the elytra shining black. Head smooth, front impressed 

 with an oblong fovea : clypeus and lower portion of face elevated into 

 a triangular space, the apex of which extends upwards between the 

 antennae ; the latter nearly the length of the body, indistinctly thick- 

 ened towards their apex, six basal joints shining, the rest opake ; eyes 

 black. Thorax nearly twice broader at the base than long ; apex entire ; 

 sides slightly rounded, quickly narrowed from the base to the apex, an- 

 terior angles produced laterally into a small obtuse tooth ; above very 

 convex, deflexed on either side in front ; surface subremotely impressed 

 with minute punctures, only visible under a lens. Scutellum smooth, 

 impunctate. Elytra broader than the thorax, more than four times its 

 length ; sides parallel ; apex acutely rounded ; above convex, each 

 elytron with ten distinctly punctured striae, the first abbreviated, each 

 stria, with the exception of the first, ninth and tenth, consisting of a 

 double row of punctures, interspaces between the fifth and ninth stria?

Colaspis humeralis. 



C. ovato-oblonga, nigro-aenea, nitida ; elytris nigris, utrisque plaga magna 

 basali rufa; tibiis posticis ante apicem spina magna, apice curvata 

 instructis. — Long. 2i lin. 



Ovate-oblong, shining nigro-aeneous ; elytra shining black, each with 

 a large subtriangular patch at the base, extending from the outer margin 

 nearly to the suture, and downwards rather more than a third the 

 length of the elytron, shining rufous. Head deeply inserted in the 

 thorax ; face perpendicular, deeply punctured, puncturing more crowded 

 on the clypeus ; antennae subfiliform, half the length of the body, black, 

 basal joints fusco-fulvous. Thorax moderately convex, nearly as wide 

 at its base as the elytra ; sides rounded and narrowed from the base to 

 their apex ; surface finely punctured. Elytra rather more than three 

 times longer than the thorax ; shoulders rounded, sides narrowly 

 margined, sinuate behind the anterior third ; apex acutely rounded ; 

 above moderately convex, transversely impressed below the shoulders ; 

 surface finely punctate-striate, the puncturing distinct in front, nearly 

 obsolete towards the apex. Body beneath obscure brassy-green ; last
