WEST INDIAN MELOIDAE — SELANDER AND BOUSEMAN 215 



Head shape nearly as in P. arizonica (Van Dyke), subtrian^lar; 

 width at tempora barely less than distance from top of vertex to base 

 of labriim; vertex weakly tumid, flattened at center; surface moder- 

 ately coarsely, densely punctate except for an ill-defined impunctate 

 area between eyes, extending laterally on each side to antennal base 

 and along midline to center of vertex. Eyes extremely large, separated 

 on front by a distance varying from Ko to % width of head at tempora, 

 separated beneath head by % to nearly Vi distance on front. Man- 

 dibles relatively short, strongly bent. Galeae lobiform, shorter than 

 labial palpi. Antennae 4% to 4% as long as pronotum, very slender, 

 setaceous; segment I definitely short of middle of eye; III as long as 

 I; II shorter; IV about % longer than III; V to X subequal, as long 

 or slightly longer than IV; XI K longer than II. Pronotum barely 

 wider than long, quadrate campanuliform; sides subparallel for basal 

 %; disk impressed on each side before middle; surface moderately 

 coarsely, densely punctate. Scutellum large, obtuse. Elytra densely 

 rugose punctate, as in P. pallida Dillon and P. megalops (Champion). 

 Hind tibial spurs enlarged, concave behind, subequal. 



Male having fore and middle tarsi distinctly swollen and expanded; 

 hind tarsi just perceptibly so. Fifth abdominal sternum moderately 

 deeply emarginate medianly, with a triangular impressed, glabrous 

 area medianl}^ Sixth sternum cleft, strongly impressed; each half 

 of sternum medianly emarginate apically, strongly recurved at base, 

 and with a small process on median margin near middle. Male
