Barin^e 405 



punctures coarse and close but with polished interspaces, the median 

 line not well defined; elytra subacutely parabolic, two-fifths (cT) to a 

 fourth (9) longer than wide, at the rather prominent humeri much 

 wider than the prothorax and a little less than twice as long; striae rather 

 coarse and deep; intervals twice as wide as the striae or a little more, 

 rugosely punctate and somewhat dull; abdomen strongly convex, not 

 modified in the male; entire under surface densely clothed with broader, 

 suboval, white scales. Length (cf 9) 3-0-3-I mm-: width 1.35 mm. 

 Costa Rica (Escazu), — Biolley. Communicated by Mr. Champion. 



This is the Central American species doubtfully referred to 

 hospes by Mr. Champion, but it differs in its smaller size, smaller 

 and sparser white squamules of the upper surface, relatively shorter 

 slender smooth part of the beak in the female, and in several other 

 features; the male differs from the male of hospes — described as 

 aciiminatus by the writer— in its relatively much longer beak, as 

 well as in the more general characters just mentioned. 



*Centrinaspis rejecta n. sp.— Elongate-rhomboid, rather more slender 

 and with relatively smaller prothorax, similar in coloration but less 

 shining, the vestiture nearly similar but longer and denser above, more 

 closely resembling that of hospes; beak (9) shorter, three-fourths as 

 long as the elytra, otherwise resembling that of parens and Jwspes, evenly 

 arcuate, smooth and black, abruptly thick and rugose in basal two- 

 fifths; antennal club oval, its basal joint more than a third of the mass; 

 prothorax small, fully a third wider than long, the converging sides some- 

 what strongly arcuate to the feebly prolonged apex, which is a little less 

 than half as wide as the base; punctures strong and very dense; scutellum 

 small, albido-squamose; elytra three-sevenths longer than wide, elongate- 

 ogival, with narrowly obtuse apex, at the somewhat prominent humeri a 

 third wider than the prothorax, almost two and one-half times as long; 

 stria deep, not coarse, the rugose intervals from much less to more than 

 three times as wide as the striae; abdomen very convex; under surface 

 and legs densely albido-squamose. Length (9)34 mm. ; width i .4 mm. 

 Mexico (Puebla). 



Differs very much from the preceding in its narrower form, longer, 



closer vestiture above and longer elytra, and, from both parens and 



iiospes, in its smaller prothorax, from the latter also in its smaller 



size and narrower outline. 



Centrinaspis optiva n. sp.— Oblong, subparallel, elongate and convex, 

 clothed closely above with yellowish-white Unciform scales, rather broad 

 on the pronotum, still broader and closer on the elytra, the scutellum 

 very densely albido-squamose, the under surface with very dense white 

 scales, those of the anterior and middle femora smaller, narrower and 

 less dense than those of the posterior femora; beak (cT) short, arcuate, 

 thick and cylindric, rather smooth and only about as long as the pro-
