VOL. G'. 



This variety was described by Sharp (1881) from Georgetown. 

 British Guiana, and its distribution extends from the type locality 

 northward into the Antilles. Kerremans (1908) records it as dis- 

 tributed throughout all the Antilles, and Fleutiaux and Salle (1890) 

 record gigantea Linnaeus from Guadeloupe, which probably refers 

 to this variety. 



The following West Indian material has been examined: Coll. 

 British Mus. : Two specimens, one labeled Guadeloupe (Tarnier) 

 and the other Cuba (Heyne). 



This form can be separated from the other varieties of this species 

 by the uniformly dark color and the almost entirely absence of the 

 discoidal spaces on the pronotum.

Head distinctly and broadly depressed on front, and narrowly 

 grooved on the occiput; front not narrowed by the insertion of the 

 antennae, the sides obliquely converging to the vertex ; epistoma ar- 

 cuateiy emarginate in front, with the lateral angles of the emargina- 

 tion obtusely rounded ; antennal cavities large, triangular, margined 

 posteriorly by an elevated arcuate carina, and situated a short dis- 

 tance from the inner margin of the eyes. Antennae short; first joint 

 elongate and moderately clavate ; second short and subglobular ; third 

 two times as long as the second, and strongly expanded at apex ; the 

 following joints robust, wider than long, strongly dentate on the 

 inner side, and both sides of the serrate joints armed with poriferous 

 pores and foveae. Eyes large, elliptical, strongly convex, and much 

 closer to each other on the vertex than at the front. Pronotum dis- 

 tinctly wider than long, narrower in front than behind, feebly con- 

 vex, more or less sulcate on the disk, and declivous at the sides; an- 

 terior margin bisinuate, with the median lobe broadly rounded ; base 

 bisinuate, with a broadly rounded median lobe; sides obliquely ex- 

 panded anteriorly, and broadly rounded posteriorly, the lateral mar- 

 gins smooth, sharply elevated, extending forward to the apical angles, 

 where they are arcuately connected to the anterior margin. Scutel- 

 lum small, wider than long, and subquadrangular. Elytra elongate, 

 feebly lobed at base; sides arcuately attenuate to the apex, which is 

 acuminate, the lateral margins strongly serrate posteriorly. Sternal 

 cavity formed by the mesosternum and metasternum; mesosternum 

 divided, the lateral branches rather short and broad; metasternum
