842 THE LATE MR. M. JAC!OBY OX NEW [NoV. 26, 



at the sides below the shoulders, the punctures in front of this 

 space interrupted ; the base in sha.pe of a transverse band ex- 

 tending downwards at the sides to below the middle and the apex, 

 pale fulvous, rest of the disc purplish blue. Below and legs of 

 the latter colour. Pr-osternum strongly produced in front, deeply 

 bilobed posteriorly. 



Hah. Havana. 



Whether this is the female of C. grossulu's Oliv., the male of 

 which was described at length by Suflrian, I do not know, but the 

 coloration is entirely different. The thorax has no yellow margins, 

 nor have the elyti-a a flavous band at middle ; they may be 

 described as fulvous with the entire disc purplish blue, this colour 

 assumes the shape of a broad band which is strongly emarginate 

 at the sides ; the colour of the body below and that of the legs 

 also differs from Olivier's species. 



Cryptocephalus cubaensis, sp. n. 



Body below dark brown, above metallic dark blue ; thorax im- 

 punctate ; elytra very deeply and closely punctured, a transverse 

 spot at the base and a narrow band at the middle flavous. 



Length 4 millim. 



5 . Elongate, the head nearly impunctate, metallic blue ; 

 clypeus fulvous ; eyes subtriangularly notched ; antennee long and 

 slender, lower five joints fulvous, rest dark, fifth and following 

 joints longer than fourth. Thorax scarcely more than one-half 

 broader than long, narrowed anteriorly, sides rounded, median 

 lobe scarcely produced ; surface entirely impunctate, blue. Scutel- 

 lum elongate and narrow. Elytra with very deep and closely ap- 

 proached rows of punctures, which only slightly diminish in size 

 towards the apex ; the last two interstices costate, the others 

 slightly wrinkled near the shoulders ; the blue ground-colour 

 interrupted by a transverse flavous spot near the scutellum at 

 the base and by another oblique narrow band at the middle near 

 the sutvire, not extending to the sides. Body below and legs dark 

 fulvous. Prosternum longer than broad, posterior margin feebly 

 concave. 



Hah. Cuba. 



Differs in coloration from any other species from the same 

 locality. 



Cryptocephalus semifasciatus, sp. n. 



Black ; thorax fulvous, minutely punctured ; elytra ferru- 

 ginous, deeply and closely punctured, a spot below the base, 

 another near the apex, and an inteiTupted transverse band across 

 suture below middle, black. 



Length 4 millim. 



Subcylindrical and parallel ; head black, closely punctured and 

 finely pubescent ; labrum fulvovis ; eyes broadly emarginate at 

 middle ; antennae long and slender, black, basal four joints ful- 

 vous, first piceous above, third and fourth equal, fifth longer.
