BARIXI. 317 



horn; be:ik more distinctly punctured and striate. Varies with the horns 

 slu>r . 



9- Prosternum flattened, but without horns; beak smoother, punctured 

 towards th. 1 base. 



Two larger specimens from Florida have the prothorax less densely punc- 

 tured, and the fifth ventral as long as the third and fourth united; in the $ 

 the horns are merely short acute cusps. They may indicate a disiinct 

 species, but I prefer not to define it as such for the present. 



24. C. prolixus, n. sp. 



Elongate, shining black, with a slight bronzed lustre, nearly glabrous 

 above. Beak slender, slightly curved, as long as the prothorax; frontal 

 impression wanting. Prothorax as wide as long, narrowed in front and 

 rounded upon the sides, broadly but not deeply constricted in front; disc less 

 convex than usual, sparsely punctured. Elytra very elongate, parallel, con- 

 jointly rounded at tip; striae fine, interspaces wide, with small distant fine 

 punctures; disc vaguely impressed behind the base. Beneath slightly pubes- 

 cent, not deeply punctured, pros' ernum broadly concave, with a small square 

 impression near the tip; front coxa3 not widely separated; metathoracic side 

 pieces narrow ; ventral segments very sparsely punctured; fifth as long as 

 the third and fourth united. Funicle of antennas rather slender, second 

 joint hardly longer than third. Length 4 mm.; .15 inch. 



Massachusetts and Illinois; three specimens. Somewhat r sembles C. 

 recttrostris, but is smaller, and quite different by the characters given 

 above. 



25. C. confinis, n. sp. 



This species exactly resembles C- concinnus in size, form and sculpture, 

 but differs by the finer pubescence, which is almost inconspicuous on the 

 upper surface, and by the prosternum having one small but deep round 

 fovea near the tip, instead of two approximate ones. Length 2.3 mm.; 

 .09 inch. 



New York; one specimen. 



ZYGOBABIS n. g. 



Body resembling in form a small robust Centrinm (e. g. picumnu*), but 

 very coarsely sculptured and not densely clothed with scales. Beak as 

 long as the head and prothorax, slender, cylindrical, curved; not trans- 

 versely impressed at the base; antennal grooves commencing nearly one- 

 third from the tip, descending obliquely; eyes rather large, transverse, not 

 convex, finely granulated, front not wider than the beak; head rather 

 small. Antennae with the first joint of funicle elongate, and stou'er than 

 the second; 2-7 gradually stouter, merging into the club, which is elongate- 

 oval, pointed, pubescent and regularly annulated, the basal joint not being 

 unduly large. Prothorax strongly narrowed in front, feebly constricted. 

 and without postocular lobes ; base Insinuate ; prosternum long in front of 

 the coxrc, which are widely separated, impressed near the front margin.
