base when viewed from above, broadly impressed before the basal constriction, 

 densely punctured and scaly in its basal half, more remotely punctured and 

 feebly shining beyond the auteunal insertion, basal tufts very prominent, a 

 smooth snbcarinseform median line from base to apex ; scrobes oblique, visible, 

 when viewed laterally, in their anterior half only. Antenna inserted at the 

 middle, first joint of funicle robust, one-half longer than the second, basal joint 

 of club subglabrous. Head polished, with a very few scattered punctures. 

 Prothorax transverse, one-half wider than long, narrowed anteriorly, widest at 

 the middle, regularly rounded on the sides, one-fourth wider at the base than at 

 the apex, the latter broadly and very obviously constricted and distinctly im- 

 pressed behind the anterior margin ; surface not densely punctured, punctures 

 small, especially toward the median line, the latter smooth, distinct, entire, base 

 feebly biemarginate ; scutel rather large, distinct, scaly. Elytra one-third wider 

 at the base than the prothorax, suboval, very feebly rounded on the sides, hu- 

 meri not prominent, rounded, stripe quite obvious, punctures distinct, approxi- 

 mate, interstitial setse whitish, suberect and not very evident. Prosternum 

 taansversely impressed, broadly emarginate, postocular lobes feeble. Thighs very 

 feebly clavate, tibife moderate, a little widened at the apex, terminal armature 

 distinct on all ; tarsi as usual, claws connate in their basal third. Length 2.75 

 mm. ; 0.11 inch.

Three males, Mr. Ulke's and my own collection. Distinguished 

 from its nearest allies, consirlctus and sordidus, by its rather small 

 size, less rounded sides and deep apical constriction of the prothorax. 



D. fulvus Lee. ^Elongate, elliptic, black, elytra and legs ferruginous, 

 densely clothed with elongate oval scales, which are bright fulvous on the upper, 

 paler on the under surface of the body. Beak almost straight, especially in the 

 female, basal constriction deep, tufts prominent. Male : punctured throughout, 

 scaly and striate from the base to the insertion of the antennae. Female: shin- 

 ing, punctured and sparsely clothed with filiform scales in basal third, finely 

 and remotely punctulate beyond. Antennge inserted a little before the middle 

 ( ^ ), or nearly two-fifths from the base ( f ), rather stout, first joint of funicle 

 stout, longer than the second, basal joint of club shining, remainder densely 

 pubescent. Head punctured, front scaly. Prothorax about as long as wide, 

 narrowed in front, feebly constricted at the apex, moderately rounded on the 

 sides; surface evenly, densely, and rather finely punctulate, median smooth line 

 and prothoracic lobes obsolete, scales arranged transversely. Elytra fully one- 

 third wider than the prothorax at its base and fully twice as long as wide, sides 

 nearly straight for one-half, thence gradually rounded to the apex, humeri rather 

 prominent; stride impressed, rather coarsely and not remotely punctured. Pro- 

 sternunj rather long in front of coxse, not deeply emarginate. Legs moderate, 

 tibiae widened toward the apex, armature very evident; tarsi very slender, 

 claws connate for fully one-half their lengtli, the posterior tibiai are slightly 

 curved in the female. Length 3.25—3.5 mm. ; 0.13—0.14 inch. 



Hab. — California, Kansas, Utah (Missouri, Nebraska, N. Mexico, 



Casey).
