Coleopterological Notices, IV. 423 



sparsely scattered throughout the upper surface, intermixed with 

 large rounded non-strigose scales of a whitish tint, especially no- 

 ticeable on the prothorax except in a large, more or less distinct 

 spot toward base on each side of the median line, and on the elytra 

 in a large rounded or subannular sutural spot before the middle, 

 along the sutural interval and near the humeri and subapical umr- 

 bones ; the alternate strial intervals with a single series of long 

 stiff erect and widely spaced setae ; under surface densely clothed 

 with large whitish scales. Beak rather long and slender, squamose 

 but only just visibly thicker toward base, distinctly longer than the 

 head and prothorax ; antennas inserted just beyond the middle, the 

 first funicular joint not as long as the next three, second and third 

 subequal, both longer than wide. Prothorax small, one-third wider 

 than long, constricted behind the apex. Elytra two-fifths wider 

 than the prothorax and a little less than three times as long, one- 

 third longer than wide. Posterior femora unarmed, rather slender. 

 Length 1.35-1.8 mm.; width 0.65-0.8 mm. 



California (Yuma) ; Arizona (Benson and Tugson). A rather 

 abundant species, easily recognizable by the mixture of large 

 rounded unevenly distributed scales and long stiff erect setae, 

 bristling on the elytra. Although the ample series before me 

 show^s great variation in size, I am unable to detect any sexual 

 differences in the structure of the beak. 



16 T. Sllbfasciatlis n. sp. — Oblong-oval, moderately convex, dark 

 red-brown ; tip of beak pale rufous ; antennal club black ; vestiture com- 

 plex, uneven in distribution, consisting of short subrecumbent and very 

 robust setae and larger rounded whiter scales, the latter especially evident 

 on the elytra along the entire sutural interval and in a wide feebly defined 

 vitta from the humeri to the subapical umbones, also in a conspicuous trans- 

 verse area, wider and subannulate toward the suture, situated scarcely before 

 the middle of the length ; the alternate strial intervals with a single series of 

 short, erect, very stout and widely spaced setae ; under surface densely clothed 

 with large rounded concave and whitish scales. Head covered with large 

 umbilicate scales, the beak moderately stout, feebly, evenly arcuate, very 

 feebly tapering from the base, a little longer than the head and prothorax, 

 densely squamose except beyond the antennae, the latter inserted at apical 

 two-fifths, short, the first funicular joint not quite as long as the next three. 

 Prothorax two-fifths wider than long, the sides convergent from base to apex 

 and feebly arcuate, the subapical constriction feeble ; apex nearly three- 

 fourths as wide as the base. Elytra one-third wider than the prothorax 

 and fully three times as long, two-fifths longer than wide, parallel at the 

 sides in more than basal half, obtusely rounded behind ; striae coarse, punc-
