 width of apical third; length, 6 mm. 849. brimleyi. 



aa. Corium with two cross-bars of silvery-gray scales, one subbasal, the 

 other at apical third. 

 6. Elytra beset with numerous suberect short black bristle-like hairs,

66. Elytra clothed only with fine recumbent pubescence, this some-

 e. Elytra yellowish-brown to dark brown, except behind posterior 

 silvery line. 

 /. Joint 3 of antennas pale, scarcely infuscated at apex; hind tibias 

 strongly compressed, almost carinate.

 sure; joint 2 of antennas gradually thickened toward apex. 



856. AMCENUS. 

 hh. Smaller, length not more than 3.7 mm. ; posterior silvery line in- 

 terrupted on corium but not broken at claval suture. 

 i. Second antennal with apical third abruptly strongly clavate, its 

 length greater than distance between tip of tylus and hind 

 margin of pronotum. 857. l/etus.

849 (— ). Pilophorus brimleyi Blatchley, 1926, 165. 



Head, pronotum and scutellum dark blackish-brown, shining; clavus 

 with inner basal third and apical half velvety-black, outer basal third 

 with an inverse wedge-shaped spot covered with a bluish bloom, which 

 extends back and broadens between the two velvety ones; corium with- 

 out a trace of the usual sub-basal whitish cross-bar of the genus, the one 

 on apical third present but short, not reaching claval suture and en- 

 closed by a small bluish area; narrow basal half and a broad cross-bar
