arcuate ; in the same sex there is a small semi-glabrous flattened 

 spot near the base of the abdomen, in which the ordinary scales 

 become very sparse small and narrow, but recumbent and not 

 modified in structure. This species may be readily distinguished 

 from picitmnus by its broader white scales, shorter beak with more 

 pronounced sexual differences, by its smaller size and more slender 

 form. Twelve specimens.

8 Centrums neglectns Lee— Proc. Am. Phil. Soc, XV, p. 310. 



Similar in form and structural characters to perscillus, but clothed 

 densely throughout with ochreous-yellow scales, broad beneath, 

 narrow and slender above, where they are unevenly mixed with 

 darker brown scales of the same kind, the brown scales forming 

 also two distant subapical spots. Beak slender, very strongly 

 arcuate, not quite one-half as long as the body in the female, the 

 antennae inserted a little behind the middle, the scape rather abruptly 

 clavate, extending barely three-fourths of the distance to the eyes ; 

 second funicular joint slender but short, scarcely one-half as long as 

 the first and a little longer than the third, the outer joints larger, 

 the club as in perscillus Prosternum flat, abruptly declivous ante- 

 riorly to the transverse constriction, the coxae moderate, remote, 

 separated by distinctly more than their own width. Length 3.6-4.0 

 mm.; width 1.7-1.8 mm. 



Texas, Louisiana and Kansas. The specimens before me are 

 females, but the male is said to have a short corneous process 

 before each coxa. The statement in the original description that 

 the second funicular joint is "nearly as long as the first," is a con- 

 spicuous error. This species is closely allied to perscillus. 



9 CentrinUS grisescens n. sp. — Feebly rhomboideo-elliptical, convex, 

 rather dull, black throughout, densely clothed throughout beneath with large 

 wide yellowish-white scales, and, on the upper surface, with squamules which 

 are narrower, and luteous-white and dark brown intermingled, the latter more 

 evident in two distant spots near the apex as in neglectus. Beak strongly 

 arcuate, relatively not longer and but slightly more slender in the female 

 than in the male, but notably more arcuate in the former sex, not quite one- 

 half as long as the body; antennae inserted as in neglectus, the second funicular 

 joint much more slender than the first and not quite one-half as long, much 

 shorter than the next two together ; club about as long as the preceding four 

 joints combined,. not very abrupt, densely pubescent, with the basal joint 

 composing but slightly less than one-half of the mass. Prothorax one-third
