AET. 9 WEST INDIAN BUPKESTIDAE FISHER 63 



tures irregularly placed and becoming denser along the eyes, the 

 intervals densely and obsoletely punctate ; epistoma broadly arcuately, 

 but feebly emarginate at middle, with a rather large obtuse tooth on 

 each side of the emargination. Pronotum one and two-third times 

 as wide as long, distinctly narrower in front than behind, widest 

 near the middle: sides broadly arcuately rounded, the lateral mar- 

 gins strongly elevated posteriorly but becoming obsolete near the 

 anterior margin, which is broadly arcuatel}^ emarginate ; base feebly 

 bisinuate, and the posterior angles obtusely angulated; surface regu- 

 larly convex, polished and shining, densely and obsoletely punctate, 

 with a number of deeper and larger punctures intermixed, the large 

 punctures very sparse on the disk, but becoming denser toward the 

 margins. Scutellum smooth. Elytra wider than pronotum at base, 

 broadly rounded behind the humeral angles, strongly sinuate at 

 the posterior coxae, behind which it is arcuatel}^ expanded to the 

 apical third, then arcuately attenuate to the tips, which are narrowly 

 and arcuately emarginate; each elytron with four more or less dis- 

 tinct longitudinal costae, and the intervals covered with vermicular 

 reliefs. Abdomen beneath smooth and shining, with a few obsolete 

 punctures, which are more abundant along the anterior margins 

 of the segments; first segment feebly con\'ex, without a median de- 

 pression; fifth segment longer than the preceding one, and broadly, 

 deeply, and angularly emarginate at the middle; last segment elon- 

 gate, rather acuminate at apex, and very deeply and broadly de- 

 pressed on each side of the median longitudinal elevation. Proster- 

 num strongly convex, and abruptly declivous along the anterior 

 margin, which is feebl}^ arcuately emarginate at middle, and form- 

 ing an obsolete lobe on each side of the emargination; prosternal 

 process with the sides feebly dilated behind the anterior coxal cavi- 

 ties, then obliquely attenuate to the apex, which is obtusely rounded; 

 surface densely and rather finely puncture, and densely clothed 

 along the middle with a fine, erect pale pubescence (more or less 

 rubbed off in some specimens), this is continued along the middle 

 of the metasternum, where it diverges into two patches, which con- 

 tinue along the inner margin of the hind coxae and hind margin of 

 the jDosterior femora. 



Female. — Differs from the male in being nearl} glabrous on the 

 underside, the fifth ventral segment elongate, more than two times 

 as long as the preceding one, strongly attenuate to the, apex, which 

 is feebly, broadly arcuately emarginate, and with the last segment 

 only feebly visible, densely punctured, and with a small notch at the 

 apex. 



Length, 60-70 mm. ; width, 25-28 mm.
