two; second shorter than next two; club 0.18 by 0.08 mm. Eyes 

 promment; frons slightly wider than dorsal tip of beak. Pro thorax 

 at base two-fifths wider than long, middle narrower than base, apex 

 three-fom-ths as wide as base; sides beyond basal lateral expansion 

 slightly expanded to middle, rounded to apex; in profile dorsal surface 

 slightly arcuate; punctation 0.03 mm. in diameter, moderately 

 shallow, interspaces less than diameter of punctures; basal fovea 

 lacking. Elytra at humeri one-third wider than prothorax at base, 

 nearly three times as long as prothorax, length to width as 4 :3; 

 intervals moderately convex, twice as wide as striae, with one row 

 of minute scales; striae moderately deep, fine. Scutellum triangular, 

 0.05 by 0.05 mm., nearly smooth. Front femora 3.6 times as long as 

 wide. Claws with acute basal tooth. 



Special male characters: Tibia 2 armed with moderately short, 

 subangulate mucro projecting in line with long axis of tibia, first 

 segment of fore tarsus with outer apical angle produced into a spine. 



Female is not known. 



Holotype: Male (USNM 63423), on banana leaf from Mexico, 

 intercepted at Brownsville, Tex., Feb. 22, 1938, No. 38-2705.

Figure 9,e,h-j 



Description: Length, 1.75 mm.; width, 0.84 mm. 



Moderately robust. Black; antennae yellow, apices of tibiae and 

 tarsi dark yellow; pubescence white, on dorsal sm-face fine, moderately 

 sparse, on sides of prothorax, mesothorax and metathorax, under 

 eyes, and base of beak denser, coarser, conspicuous. Beak of male 

 shorter than head and prothorax combined, one-fom^th longer than 

 prothorax, slightly curved; in dorsal view slightly expanded laterally 

 at antennal insertion, strongly attenuate to apical two-thirds, apical 

 third strongly expanded; basal two-thirds dull, alutaceous, punctured, 

 pubescent, apical third shining, sparsely punctured. Antennae 

 inserted at basal fourth of beak, at distance from eye equal to width 

 of frons; first segment nearly equal to next three, second segment 

 equal to next two, club 0.21 by 0.08 mm. Eyes prominent; frons 

 slightly wider than dorsal tip of beak. Prothorax at base one-fifth 

 wider than long, middle slightly narrower than base, apex three- 

 fourths as wide as base; sides beyond basal lateral expansion nearly 

 parallel to middle, rounded to constricted apex; in profile dorsal 

 surface nearly flat; punctation shallow, 0.03 mm. in diameter, inter- 

 spaces slightly less than diameter of punctures; basal fovea shallow, 

 punctiform. Elytra at humeri one-half wider than prothorax at base, 

 2.6 times as long as prothorax, length to width as 13 : 10; intervals 

 nearly flat, equal in width to two striae, with one row of scales;
