4 Centrinus modestus Boh.— Sch. Cure, III, p. 772. 



A well-known species of robust, oval, strongly convex form and 

 piceous color, sparsely sprinkled with coarse white scales and nar- 

 rower brownish squamules above, and more densely covered with 

 whitish scales beneath. The beak is about one-half as long as the 

 body, evenly but not very strongly arcuate, moderately stout, 

 slightly gibbous at base, so that it is separated from the head by an 

 unusually deep and sharply marked transverse impression ; antennae 

 normal, inserted a little beyond the middle, the scape short, extend- 

 ing about two-thirds the distance to the eyes, the second funicular 

 joint scarcely more than one-half as long as the first. Prothorax 

 strongly constricted and almost tubulate at apex. Prosternum 

 with a deep oval abruptly glabrous subapical spot, which is very 

 deeply and transversely excavated at the bottom, and continued 

 posteriorly by a feebly defined canaliculate and squamose impres- 

 sion, which becomes narrower and gradually evanescent before the 

 coxse, the latter large and separated by scarcely more than one- 

 fourth of their own width, with the middle of the anterior margin of 

 the acetabula elevated in a feeble cusp-like prominence, or short corne- 

 ous process in the male. Length 4.0-4.5 mm.; width 2.3-2.5 mm. 



The four specimens in my cabinet are from Pennsylvania and 

 Florida. In well preserved specimens a small spot of dense scales 

 is evident at each side of the scutellum, and another just before 

 each humeral callus, the former not being as large or conspicuous, 

 however, as in striatirostris. 



5 Centrinus tortuosus n. sp. — Rather robust, feebly rhomboid-oval, 

 convex, shining, coarsely sculptured, piceous-black, the antennae paler ; ves- 

 titure very sparse above, consisting of large white scales and small narrow 

 brown squamules indiscriminately mingled on the elytra, dense beneath, and 

 with the scales white, short, broad and truncate. Head almost completely 

 impunctate, the transverse constriction abrupt, almost in the form of a groove ; 

 beak rather stout, feebly arcuate, very coarsely, deeply, longitudinally punc- 

 tate and rugulose at the sides, a little longer than the head and prothorax in 

 the male, the antennae inserted distinctly beyond the middle, the scape short, 

 second funicular joint one-half as long as the first and nearly as long as the 

 next two, club well developed, oval, abrupt, densely pubescent, about as long 

 as the preceding five joints together and with its basal joint composing about 

 one-half of the mass. Prothorax three-fifths wider than long, the sides dis- 

 tinctly convergent and almost straight from the base to apical third, then 

 broadly rounded and convergent to the deep apical constriction, the apex 

 strongly tubulate, truncate, not quite one-half as wide as the base, the latter 

 transverse and perfectly straight, the median lobe less than one-third of the
