AUT. 9 WEST INDIAN BUPRESTIDAE FISHER 203 



arcuately emarginate in front; antennal cavities large, triangular, 

 and extending to the inner margin of the eyes. Antennae rather 

 long, and dentate from the fourth joint; first and second joints 

 thick, the first slightly longer than the second, which is globular; 

 third elongate and more slender than the second; the following joints 

 elongate, triangular, wider in front, dentate on the inner side, and 

 armed with a terminal poriferous fovea. Eyes rather large, oval, 

 partially covered bj' the pronotum, a little oblique, and slightly 

 closer together on the occiput than at the bottom of front. Prono- 

 tum wider than long, convex ; anterior margin arcuately emarginate ; 

 sides arcuately rounded, with a lateral carina parallel to the anterior 

 margin, which is not visible from above; base transversely truncate. 

 Scutellmn small and feebly triangular. Elytra convex, truncate, 

 and transversely impressed at base; sides nearly parallel in front, 

 and broadly rounded behind. Sternal cavity formed entirely by the 

 metasternum, the mesosternum invisible. Metasternum broad and 

 nearly truncate in front. Prosternum wide, convex at middle; an- 

 terior margin truncate or arcuately emarginate; prosternal process 

 rectangular and truncate at apex. Middle coxae not more widely 

 separated than the anterior ones, the posterior pair nearly contig- 

 uous, and the sides parallel and scarcely dilated internally. Legs 

 only feebly robust and not contractile; femora slightly swollen at 

 middle; tibiae slender and cylindrical; tarsi very short; tarsal claws 

 broadly toothed at base. Body oblong, subcylindrical, and equally 

 rounded in front and behind. 



This genus contains a small number of species which are dis- 

 tributed from the United States to South America, and so far only 

 one has been recorded from the "West Indies. 



MASTOGENIUS UNIFORMIS Waterhouse 



Mastogenius uniformis Waterhouse, Ann. and Mag. Nat. Hist., ser. 6, 

 vol. 18, 1896, pp. 105-106. 



The following is a copy of Waterhouse's original description: 



Aureo-aeneous, convexus, sat nitidiis, subtiliter punctulatus ; capite convexa, 

 fronte vix canalieulata ; thorace lateribiis leviter arcuatis, basi triincato ; elytris 

 subparallelis, apice arciiatim attenuatis ; antennis pedibiisque fere nigris, tarsis 

 brevibus flavescentibus. 



Long. 2 mill. 



Hab. Mount Gay Estate (Leeward side), Grenada, W. I. (H. H. Smith). I 

 do not know of any Buprestid quite of this form; it reminds me somewhat of 

 Aurigena in its outline, but has the thorax rather broader and more convex^ 

 The surface, when examined with the microscope, has somewhat the appear- 

 ance of leather. Head convex, finely and not very closely punctui-ed, with a 

 slight median impressed line; below with a groove bordering the eye for the 

 reception of the basal joints of the antennae, the groove continued on the 

 sternum, but becoming gradually narrower and terminating about halfway 

 between the front margin and the coxae. Antennae as long as the head and 

 thorax together, the two basal joints moderately stout, the third joint rather 

 slender, the following joints triangular, the terminal joint elliptical. Thorax 

 transverse, convex, almost rectilinear at the base, not much narrowed at the
