seventh and ninth interspaces widened and elevated posteriorly, with 
a uniseriate row of bristles; eighth narrowed posteriorly. Declivity 
rounded, originating well behind middle; first stria distinctly im- 
pressed, others very lightly or not at all impressed; vestiture nearly 
entirely lacking on anterior half, posterior disk, sides, and declivity 
with widely spaced, erect, stout, yellowish hairs. 
Male—Very similar to female, but with frons triangularly concave 
(not so deep as in guianae) ; the concavity shining (not granulate at 
sides as in guzanae), finely punctured, and with inconspicuous, short 
hairs; median carina fine, as in female, elevated, completely bisecting 
concavity. 
Type locality —Trinidad, British West Indies. 
Hosts —Hymenaea sp.; Erythrina sp. seed. 
Type material—Holotype, allotype, and 34 paratypes, U.S.N.M. 
No. 56004. 
The holotype, allotype, and 30 paratypes were taken at the Plant 
Quarantine station, at New Orleans, from the pods of Hymenaea sp.; 
4 paratypes were intercepted at quarantine, at New York, in seeds of 
Erythrina sp. 
NEODRYOCOETES GUIANAE, new species 
PLATE 20, FIicurE 12 
Female.—Light reddish brown, 1.77-1.94 mm. long; holotype 1.86 
mm. long, 2.63 times as long as wide; allied to caribaeus, new species, 
but slightly larger, less shining, and differently sculptured on pro- 
notum and elytra. 
Frons flattened below between eyes, finely, very densely punctured, 
with very fine hairs, longer and more numerous than in caribaeus; 
median carina rather fine, distinctly elevated; vertex subopaque, finely 
reticulate, shallowly, not closely punctured. Eye very large, with 
facets coarse, half divided by a deep emargination. Antenna (fig. 12) 
with club obovate, 1.32 times as long as wide, 1.5 times as long as 
funicle, first suture notched at sides, arcuate, strongly, incompletely 
septate; second and third sutures indicated only by setal rows. 
Pronotum 1.08 times as long as wide, widest through base, posterior 
outline arcuate, distinctly margined; sides nearly evenly arcuate from 
base to anterior lateral constriction, moderately rounded in front 
(more narrowly than in caribaeus), anterior margin scarcely serrate; 
dorsal contour evenly arcuate from base to apex; anterior area rather 
weakly asperate; posterior area with surface feebly shining or 
subopaque, finely reticulate, punctures moderately large and deep 
(larger and deeper than in caribaeus), their outer rims scarcely or not 
at all elevated; median line impunctate, only feebly elevated.
