from perscilla in its smaller size, more abbreviated form and more 

 rapidly acuminate elytra ; the scales of the upper surface are broadly 

 linear and brownish-white and dense, though similarly not con- 

 cealing the striae. The following is a species even smaller than 

 finitima and notably narrower, though agreeing very well in many 

 respects : 



Centrinaspis profecta n. sp. — More evenly and less broadly oval than 

 finitima, black, with more or less rufescent legs; scales of the upper 

 surface rather broadly linear, pale yellowish and close-set, larger, whiter 

 and dense on the under surface; beak arcuate, nearly half as long as the 

 body, distinctly thicker basally and thinner apically in the female, but 

 only little longer; antennae inserted somewhat behind ( 9 ) to distinctly 

 beyond (cf ) the middle; prothorax two-fifths to nearly one-half wider 

 than long, the sides broadly arcuate, more so anteriorly, becoming 

 gradually subparallel basally.the apex feebly subtubulate, slightly less 

 than half as wide as the base; punctures moderate and dense; scutellum 

 small; elytra parabolic, narrow at tip, a third longer than wide, only 

 very slightly wider than the prothorax and two-thirds longer; striae 

 moderately coarse, deep, the intervals alternating but slightly in width, 

 between two and three times as wide as the striae; presternum with 

 feeble apical constriction, separating the coxae by nearly their own width, 

 the spines of the male short and erect; second funicular joint of the 

 antennae slender, shorter and thinner than the first but as long as the 

 next two. Length 2.65-3.4 mm.; width 1.15-1.45 mm. Alabama 

 (Mobile) and Texas (Columbus). Many specimens. 



Differs from finitima in its narrower and less rhomboidal outline, 

 the prothorax being more nearly equal in width to the elytra, and 

 in its slightly shorter beak; it varies considerably in size of the body. 



Centrinaspis nacta n. sp. — Rather stout, subparallel, attenuate behind, 

 black, the legs and antennae rufescent; upper surface clothed loosely 

 with narrow ashy scales, not concealing the integument and forming 

 two irregular lines on each strial interval, the under surface with larger 

 whitish scales, which are narrowly separated; beak in the male evenly 

 arcuate and very feebly tapering throughout, slightly more than half 

 as long as the body, the antennae inserted slightly beyond the middle, the 

 second funicular joint long and slender but shorter and much narrower 

 than the first, the third slightly elongate, the club narrowly oval, with 

 its first joint constituting about two-fifths of the mass; prothorax large, 

 fully two-fifths wider than long, the sides subevenly rounded but be- 

 coming parallel gradually toward base, the apex briefly and feebly 

 constricted and much less than half as wide as the base; punctures 

 rather coarse, close and partially confluent, the smooth line irregularly 

 traceable centrally; elytra two-fifths longer than wide, arcuately acum- 

 inate and with narrowly obtuse apex, subequal in width to the prothorax 

 and four-fifths longer; striae moderate, deep; intervals between two and
