Baring 395 



three times as wide as the striae and loosely, coarsely punctato-rugose, 

 shining; male with the prosternum deeply excavated centrally, the coxae 

 well separated, the spines erect and rather short. Length (cT) 3.5 mm.; 

 width 1.55 mm. Texas (Houston), — Wickham. 



This rather distinct species differs from both profecta and finitima 

 in the deep central excavation of the prosternum in the male, in 

 the sparser whiter vestiture of more slender scales, forming only 

 two lines on each strial interspace, and in the somewhat longer beak. 



Centrinaspis debilis n. sp. — Smaller and narrower than profecta, nar- 

 rowly subrhomboid-oval, piceo-rufous in color, the legs brighter rufous; 

 upper surface clothed with linear yellowish scales, conspicuous but 

 everywhere slightly separated; under surface with broader, oval, denser 

 scales; beak in the male evenly arcuate, nearly half as long as the body, 

 rather slender, punctured and squamulose, the antennae inserted near 

 four-sevenths; prothorax nearly a third wider than long, the sides feebly 

 converging and slightly arcuate, gradually more so before about the 

 middle, the apex scarcely constricted; punctures dense, in great part 

 longitudinally confluent, the smooth median line traceable in part; 

 elytra a third to nearly half longer than wide, gradually obtusely acum- 

 inate, with arcuate sides and feeble humeral swellings, very slightly 

 wider than the prothorax and three-fifths to three-fourths longer; grooves 

 moderate; intervals rather more than twice as wide as the grooves, not 

 very densely rugulose, the scales disposed in two lines on each; scales 

 of the abdomen distinctly and evenly separated. Length (cf") 2.25- 

 2.7 mm.; width 0.8-1. 15 mm. Alabama (Mobile). Two specimens. 



Differs from profecta in its narrower outline, paler coloration, 

 narrower prothorax, the punctures of which are more longitudinally 

 confluent, and in the bilineate and not broadly confused scales of 

 the strial intervals. 



Centrinaspis tenuicula n. sp. — Body narrowly subrhomboid, attenuate 

 behind from the slightly swollen humeri, black, not at all shining, the 

 legs and antennae slightly rufescent; upper surface clothed with decum- 

 bent lineiform ochreous scales, evenly distributed over the pronotum and 

 comparatively narrow interstrial surfaces, more oval, dense and whitish 

 on the under surface; beak in the male moderately arcuate, gradually 

 tapering, half as long as the body and squamose basally; antennae 

 inserted just beyond the middle, nearly as in nacta; prothorax smaller, 

 between a third and fourth wider than long, the sides just visibly con- 

 verging and very feebly arcuate, gradually rounding before the middle, 

 the obsoletely constricted apex about half as wide as the base; punctures 

 moderately coarse, dense, the smooth median line not visible; elytra 

 more than two-fifths longer than wide, with the long converging sides 

 only very feebly arcuate and the apex rather narrowly rounded, distinctly 

 wider than the prothorax and fully three-fourths longer; striae deep, 

 somewhat coarse, the intervals about twice as wide as the striae; male
