5 — Body stout in form, polished, pale piceo-testaceous in color, the head 

 and elytra, the latter broadly and gradually toward the external apical 

 angles, black; legs and antennae flavate; head and pronotum finely, 

 obsoletely micro-reticulate, the elytra and abdomen more coarsely and 

 strongly so; head coarsely, sparsely punctate toward the sides, the 

 prothorax rather distinctly wider than the head, nearly twice as wide 

 as long, almost as in fasciata throughout; elytra slightly wider and 

 one-half longer than the prothorax, the humeri only very narrowly 

 exposed, rounded, the punctures verv fine, asperuiate and sparse; ab- 

 domen at base nearly as wide as the elytra, much narrower at apex, 

 subimpunctate except sparsely along the apices of the tergites. Male 

 with the two apical processes angulate at tip, the median lobe broadly 

 angulate and advancing about half way to the line of their apices, the 

 surface strongly swollen and smooth; external apical angles of the 

 elytra only very narrowly and feebly, longitudinally swollen; female 

 nearly as in fasciata, except that the emargination is rather broader 

 and almost evenly circular in curvature between the angulate apices, 

 the latter less dentiform. Length 1.3-2.3 mm.; width 0.65-0.85 mm.

6 — Form only moderately stout, subparallel, polished, smaller in size, pale 



rufo-flavate in color, the head and elytra black, the latter testaceous in 

 anterior half at the sides, the pale color obsolete at the scutellum; head 

 aad pronotum finely and very obsoletely micro-reticulate, the elytra 

 and abdomen somewhat strongly so; head with a few coarse sparse 

 punctures except broadly along the median line; antennae moderate; 

 prothorax distinctly wider than the head, almost twice as wide as long, 

 nearly as in fasciata throughout; elytra slightly wider than the pro- 

 thorax and but little more than a third longer, the humeri only slightly 

 exposed, rounded, the punctures rather strong, asperate and sparse; 

 abdomen at base subequal in width to the elytra, moderately tapering 

 thence to the tip, sparsely punctulate along the apices of the dorsal 

 plates as usual. Male with two short slender acute processes at the 

 apex of the sixth tergite as usual, but with the bottom of the inclosed 

 sinus only very feebly produced in the middle as a broadly rounded 

 lobe; external apical angles of the elytra but very slightly and briefiy 

 swollen; female with the sixth tergite nearly as in fasciata. Length 

 1.3-1.8 mm.; width 0.65-0.78 mm. Cuba (Cayamas),— C. F. Baker.

7 — Body rather stout, suboval, polished, very pale luteo-flavate, the head 



piceous to black, the abdomen sometimes with a small iafumate cloud 

 at about the fourth tergite; legs and antennae very pale; head and 

 pronotum not at all micro-reticulate, the elytra faiutly and obsoletely, 

 the abdomen very distinctly &o; head with some scattered coarse punc- 

 tures as usual, the eyes separated by scarcely twice their own width; 

 antennae moderate; prothorax distinclly wider than the head, about 

 twice as wide as long, widest rather distinctly before the middle, the 

 sides more rounded anteriorly, the base arcuate, the surface nearly
