 Bend, British Columbia (Hubbard and Schwarz collection). 



Length, 10 mm.; width, 4 mm. 



Bl^ck, densely clad with silvery and light pinkish rounded scales 

 and with interspersed short subrecumbent setse. Legs and antennae 

 reddish piceous to black. 



Beak but little longer than head from which it is separated by a 

 shallow transverse depression; vestiture densest on vertex, becoming 

 sparsest at apex of beak; setae line and recumbent; surface very 

 coarsely rugosely punctate; nasal plate poorly defined, crescenti- 

 form. Scrobes subterminal, deep, and sharply defined at apex, but 

 evanescent behind; scape almost reaching posterior edge of eyes; 

 funicular joints all elongate; the first and second longest, seventh 

 longer than sixth; club narrow, pointed, as long as the first two 

 funicular joints, distinctly annulate; Eyes oval, narrowest below. 

 Prothorax a little wider than long, truncate at base and apex, laterally 

 convex, transversely constricted before apex; ocular lobes broad but 

 not strong, vibrissas short, golden. Elytra widest behind middle, 

 humeri small but distinct; interspaces convex, alternately more so; 

 stride not impressed; strial punctures setigerous, large, round, deep, 

 and widely separated; scaly vestiture dense, setae small and sparse; 

 sutural interspaces separately tuberculate at summit of apical decliv- 

 ity. Undersides shallowiy punctate, densely squamose with longer 

 scales; the third and fourth abdominal segments sparsely clad, the 

 fifth very strongly setigerous. Anterior and median tibiae denticu- 

 late, anterior and posterior tibiae strongly bent near apex, all tibiae 

 mucronate, apical area of posterior tibiae very narrow.

 at apex of beak; setae sparse, fine, recumbent. Surface rugosely 

 punctate ; nasal plate hemispherical, concave, poorly defined, basally 

 notched at middle. Scrobes subterminal, deep, and sharply defined 

 at apex, but evanescent behind; scape reaching posterior edge of 

 eyes; funicular joints elongate, the first and second longest, seventh
