The paratype differs slightly from the type in having the pos- 

 terior coxae, median part of first abdominal segment, and the last 

 abdominal segment (except the extreme tip) pale yellow. 



This species is very closely allied to thoradca Fleutiaux and Salle, 

 described from Guadeloupe, but it differs from that species in being 

 black, with pale yellow markings, pronotum entirely pale yellow, 

 without a longitudinal, elevated, median line, scutellum black, and 

 the femora black, with the basal halves yellow. This may prove 

 to be only a color variety of thoradca^ when more material is avail- 

 able for study. 



NEOCLYTUS PALLroiCORNIS. new species 



Female. — Small, elongate, rather robust, subcylindrical, uniformly 

 black, except the antennae and tarsi, which are pale reddish yellow; 

 elytra ornamented with white pubescent markings. 



Head coarsely, confluently ocellate-punctate, rather densely clothed 

 with short, erect, white hairs, front as long as wide, flat between the 

 antennal tubercles, which are vaguely elevated; eyes round, rather 

 small, feebly emarginate, and moderately convex. Antenna extend- 

 ing slightly beyond base of elytra, and the outer joints strongly 

 enlarged; first joint long, cylindrical, slightly enlarged toward apex, 

 as long as the third and fourth joints united, which are subequal 

 in length. 



Pronotum distinctly wider than long, subequal in width at base 

 and apex, and widest at middle; sides strongly, arcuately rounded, 

 narrowly constricted at base; disk strongly convex, slightly uneven, 

 with four strongly elevated, transverse, median ridges, the second 

 ridge from anterior margin not quite so distinct as the other ridges ; 

 surface densely, finely ocellate-punctate, anterior half sparsely 

 clothed with short, recumbent, white hairs, which do not conceal the 

 surface, basal half sparsely clothed with fine, erect, inconspicuous, 

 black hairs. Scutellum triangular, broadly rounded at apex, and 

 sparsely pubescent. 



Elytra two and one-half times as long as pronotum, and at base 

 subequal in width to the pronotum at middle ; sides feebly narrowed 

 from base to apical fifth, then arcuately narrowed to the tips, which 

 are conjointly, deeply, broadly, arcuately emarginate ; disk strongly 

 convex; surface very finely, densely punctate, or granulose, rather 

 densely clothed with very short, inconspicuous, black pubescence, 

 and each elytron ornamented with short, recumbent, white pubes- 

 cence as follows: A narrow fascia extending obliquely backward 

 from the humerus to the sutural margin near middle, numerous ir- 

 regularly distributed hairs between it and the scutellum, a V-shaped 

 fascia at middle near lateral margin, a transverse fascia behind
