wide as the striae; male with the abdomen very faintly impressed 

 and scarcely less squamose medio-basally. Length (cf 9 ) 2.8- 

 3.0 mm.; width 1.15-1.2 mm. Mexico (Vera Cruz). Three 

 examples *ovulatus n. sp. 



Body less broadly oval and more subrhombic, convex, shining, black, the 

 legs obscure rufous, the squamules above whitish throughout, the 

 lateral pale pronotal vittae rather well defined, the median usually 

 loose and not so well defined ; strial intervals for the most part with 

 single lines of slender squamules, the scutellum small, densely 

 clothed; white scales below dense; beak (cT) thick, evenly arcuate, 

 strongly sculptured and not quite as long as the head and prothorax, 

 or ( 9 ) distinctly more slender, only a little longer, less sculptured 

 and feebly arcuate, but more rapidly arcuate and thickened at base; 

 antennae at three-fifths (cf), or just beyond the middle (9); pro- 

 thorax a sixth wider than long, the sides broadly arcuate and con- 

 verging in about apical half, more parallel and very feebly arcuate 

 posteriad; apex very faintly constricted; punctures smaller and 

 sparser than in the preceding, separated by nearly twice their 

 diameters (9 ), or by their diameters (cf ), being sensibly coarser in 

 the male; elytra longer, narrower and more gradually and recti- 

 linearly attenuated than in ovulatus, rounded at tip, at the rather 

 prominent humeri distinctly wider than the prothorax, not quite 

 twice as long, the striae deep and abrupt; intervals about twice as 

 wide as the striae; male sexual characters nearly as in the preceding. 

 Length (cf 9) 2.7-2.8 mm.; width 1.1-1.15 mm. Costa Rica 

 (Cachi), — BioUey. Two specimens. [N. lineicollis Chmp., nee 

 Boh. — pars] *ordinatus n. sp. 



10 — Form narrow, elongate-oval and convex, shining, black, the legs 

 rufous; ||[squamules above whitish, the three pronotal lines very 

 • loose and indistinct; scutellum and basal thoracic lobe densely 

 albido-pubescent; strial intervals each with a single line of long and 

 slender white squamules; scales beneath white, dense; beak in the 

 male thick and heavy, evenly cylindric and evenly arcuate, as long 

 as the head and prothorax, strongly sculptured, the antennae rather 

 behind three-fifths; prothorax as long as wide, the sides just visibly 

 converging and nearly straight, gradually feebly arcuate in nearly 

 apical half, the apex unconstricted; punctures small but deep, 

 separated by twice their diameters; elytra shorter than in ordinatus, 

 the sides much less oblique and the apex more obtusely rounded, a 

 little wider than the prothorax and three-fourths longer; striae 

 moderate, rather less than half as wide as the intervals; male with 

 the abdomen feebly impressed atid more scantily squamose medio- 

 basally. Length (cf) 2.3 mm.; width 0.9 mm. Costa Rica 

 (Cachi), — BioUey. One example *convexiilus n. sp. 



Form very narrowly elongate-oval and convex, shining, black, the legs 

 bright rufous; squamules above whitish, the three lines of the 

 pronotum loose and not very definite in the type; scutellum and 

 basal thoracic lobe closely squamose; strial intervals each with a 

 single thin line of scales; under surface with the usual dense white 

 scales; beak in the female thick, cylindric, moderately and evenly
