XORTH AMERICAN COLKOPTERA. 88 



one-balf wider than thorax, convex ; parallel for three-fourths their length, then 

 gradually narrowed and conjointly rounded at tip. Posterior callus slightly 

 evident ; striae rather broad, well impl-essed, with close set, subquadrate punc- 

 tures, almost completely concealed by the scaly vestiture; interstices slightly 

 convex, each with a row of stout, claviform seta?. Beneath not very densely 

 punctured, third abdominal segment less so; last three segments paler. Legs 

 piceous. Length 4-5 mm. ; .16-.20 inch. Plate I, fig. 2. 



Z . Last ventral with a vaguely impressed, subtriangular space. 

 9 . Last ventral with apical, triangular fovea. 

 Easily recognized by the peculiar thoracic scales and sculpture. 

 Hab. — Florida, Georgia. 



HYPERODBS Group. 



Rut two species, known to me, belong to this group. The beak is 

 cylindrical, scarcely wider at base than at apex. Prothoracic lobes 

 feeble ; legs long and slender ; tibiae incurved at apex with a smooth 

 groove in their distal half internally, not denticulate along the inner 

 margin, but more strongly emarginate than is usual in this genus; 

 densely scaly, scales have a more or less metallic lustre. The two 

 species are from the Pacific slope, and appears to be very rare; they 

 are readily distinguished as follows : 



Antenute slender, second joint of funicle longer than the first ; no frontal fovea. 



hyperodes. 

 Antennje stouter; first and second joints of funicle equal ; distinct frontal fovea. 



neva<lens«is, 



M. liyperortes n. sp.— Eather slender, elongate; piceous black; moderately 

 convex ; densely covered above and below with small, round scale.s, varying in 

 color from brassy, ochreou-j brown to grayish, intermixed with fine, short, sub- 

 erect hairs. Head and rostrum distinctly longer than thorax; beak moderately 

 stout, cylindrical; a median elevated line, entire; no trace of a lateral carina; 

 densely covered, like the bead with small brassy cupreous scales. Autennse 

 slender, with the second joint of funicle distinctly longer than first, 3-5 snb- 

 moniliform; 6-7 slightly transverse; clava darker. Head slightly convex. Eyes 

 large, broHdly oval, oblique. Thorax slightly wider than long, somewhat nar- 

 rower at apex than at base; latter feebly, sides broadly rounded and very nar- 

 rowly constricted at tip. A narrow median vitia and a bisinuate lateral one each 

 side of paler color. The fine hairs intermixed with the scales are almost pros- 

 trate and directed backward. Elytra one third wider than the thorax, slightly 

 narrowed from liase to about three-fourths their length, then more rapidly to 

 and conjointly rounded at tip. Strise well impressed with rather large, sub- 

 quadrate, not very closely placed punctures; intervals flat (slightly convex 

 where denuded), finely punctulate and each with a row of moderately long, but 

 slender setse ; an oblique impression near the base, extending from the fifth to 

 second interstice; underneath densely scaly, intermixed with short hairs. Legs
