P. voxtitus n. SI). PI. xiv, figs. 5, 35«. — Elongate oblong, black, above 

 (icnsely clothed with dark gray and intermingled with pale scales, the vestiture 

 having a faint bluish reflection : scales on the underside uniformly grayi.sh white. 

 Beak and head densely punctulate and thinly clothed with very small, piliform 

 scales, beak with an obscure elevated line; prothora.\ scarcely one-half wider 

 than long, feebly constricted at the ape.K, dorsal channel entire, somewhat ex- 

 jianded aTid more deeply impressed behind the ai>ical constriction, sides well 

 rounded, lateral tubercles obtuse, disc finely and closely punctured, scales not 

 crowded, sides and dorsal channel a little more densely clothed with whitish 

 seniles, basal margin straight eacli side. Elytra nearly two-fifths wider at the 

 base than the i)rothorax, subparallel on the sides, strise rather wide, not deeply 

 impressed, punctured, punctures concealed by the scales, interspaces wide, a little 

 convex with the scales intact, a distinct post-scutellar spot of white scales. Length

% . Last ventral not imjiressed. 



Hab. — Indiana. A male specimen in Mr. Ulke'.«i coll. Easily 

 recognized by its elongate form, very dense, scaly vestiture, and the 

 very small, lateral thoracic tubercles. 



PEL,EXOMl'S Thomp. 



This genus has for its type Phytobius camari Herbst, an insect 

 resembling, in size and general appearance, P. cnvifrons Lee, but is 

 less stout. Beak robust, more or less widened towards the apex, 

 scrobes oblique, antennal funicle 6-jointed. Eyes rounded, more or 

 less convex and entirely uncovered in repose; prothorax wider than 

 long, narrowed in front, without ocular lobes. Elytra oval, wider 

 at the base than the prothorax ; scutel very minute ; prosternum 

 very short in front of the coxa? without ante-coxal ridges, mesoster- 

 num declivous, truncate posteriorly, side pieces wide, ascending, 

 visible from above ; metasternum about as long as the second ventral 

 segment at its middle, side pieces wide; ventral segments 1-2 rather 

 long, the latter fully as long at its middle as the following two seg- 

 ments together, segments 3-4 short,, third not narrowed on the sides ; 

 anterior coxre narrowly separated, scarcely one-third the distance of 

 the middle coxte, not very prominent, middle coxre subglobose and 

 latlici- widely separated. Legs slender, femora mutic, tibiae slender, 

 unarmed, po.sterior of the male with a very small mucro, third joint 

 (if tarsi bilobed, claws simple. 



The species are distinguished as follows : 



.\lternate elyti-al interepaces with a row of tubercles CM\ ifroiis. 



Elytra not tuberculate. 



Antennffi more slender, second joint of funicle distinctly longer than the third, 

 fourth tarsal joint much shorter than joints two and three combined. 



PI. xiv, fig 38 sulcieollis. 



Antvnnaj stouter, joints 2-3 of funicle equal, or nearly so.
