much smaller. There is but one tarsal claw, which is simple and 

 moderately stout. 



The close relationship existing between Barilepton and Barinus 

 affords another illustration, parallel to that of Eisonyx and Oomor- 

 phidius previously mentioned, of the slight value to be attached, 

 among some of the centrinide genera, to radical differences in the 

 tarsal ungues, in comparison to the significance attending these 

 modifications in the baride series. 



Our four species of Barilepton may be thus defined : — 



Elytra at base not wider than the base of the prothorax. 



Beak almost evenly arcuate 1 filiforme 



Beak strongly bent near the base ; body much smaller and still more slen- 

 der ; pronotal vestiture decidedly sparser 2 famelicum 



Elytra at base wider than the contiguous base of the prothorax ; form a little 

 stouter, the prothorax much less elongate. 



Prothorax constricted behind the apex ; antennal club robust ; basal joint 

 of the hind tarsi longer, the second not quite as wide as the third and 

 rather longer than wide, the third a little wider than long. 



3 quadricolle 



Prothorax without trace of subapical constriction ; antennal club much 

 less robust ; basal joint of the hind tarsi shorter and thicker, the second 

 equal to the third and not longer than wide, the third scarcely as wide 

 as long 4 falciger

Cylindrical, convex, shining but very densely clothed with large 

 broad pale scales, sparser on the pronotum except at the sides, pale 

 fulvous on the elytra but white along the flanks and in a feebly 

 defined streak attaining the base at each side of the scutellum. 

 Head and basal parts of the beak punctured and squamose, the 

 impression obsolete but with a small inconspicuous median fovea ; 

 beak distinctly shorter than the prothorax, stout, arcuate, compressed 

 toward base, smooth and almost impunctate, the antennae inserted 

 near the middle, the basal joint of the funicle as long as the next 

 five together, the second slightly longer than the third ; club mode- 

 rately stout, as long as the first funicular joint, the basal joint appa- 

 rently large. Prothorax about as long as wide, sometimes feebly 

 dilated at apical third, generally parallel, broadly rounded toward 

 apex, the constriction obsolete ; apex fully three-fourths as wide 

 as the base; punctures deep, moderately coarse and not quite in 

 mutual contact. Elytra about as wide as the prothorax and barely 

 two and one-half times as long, the fine striae indicated by narrow
