56 H. C. FALL. 



Elytra two and three-fourths times as long as the thorax, and about 

 one-fifth longer than wide; elytral costas inconspicuous, first intercostal 

 space with confused punctures, the second and third with the row of 

 punctures somewhat irregular. Pygidium somewhat sparsely punc- 

 tured. Body beneath sparsely rather finely punctate at sides, still 

 more sparsely at middle. Legs slender; upper tooth of front tibia 

 sub-median; hind thighs with but few punctures at middle; ungual 

 tooth nearly median in position, its tip nearly equally distant from 

 base and apex of claw. Length 7.6-8.7 mm.; width 4.2-4.G mm. 



The type of this species was found near the Gila River in 

 Arizona. The only other specimens known to me were taken 

 by Dr. Fenyes at Palm Springs, California, on the western 

 border of the Colorado Desert. 



The thoracic impressions are deep and conspicuous in some 

 examples, but in others, including the type, they are nearly 

 wanting. The margins of the body are moderately fimbriate, 

 the legs more conspicuously so than usual. The rotundate 

 clypeus and short median ungual tooth are the two most 

 important characters, and these when combined with the 

 form and sculpture of the prothorax, make the species easy 

 of indentification. 



46. I>. fimbriata n. sp. 



Broadly ovate, black, shining, scarcely detectably alutaceous, even 

 on the elytra; sides of body very conspicuously fimbriate with very 

 long hairs. Mentum declivous anteriorly, the margin of the declivity 

 raised. Front and clypeus in same plane, clypeal suture distinct but 

 lightly impressed; clypeal margin rotundate, faintly sinuate or sub- 

 sinuate at middle, narrowly reflexed; head densely punctate. Pro- 

 thorax not quite three-fourths wider than long, widest at middle, base 

 a little wider than apex, sides rather strongly arcuate, all angles obtuse; 

 disk evenly convex, densely punctate laterally, the punctures distant 

 from one to two times their diameters at the middle. Elytra ovate, 

 about one-seventh longer than wide and barely two and one-half 

 times as long as the prothorax; costag not at all evident; punctures of 

 first broad interspace confused, elsewhere in regular rows, except just 

 within and behind the humeri. Pygidium densely coarsely punctate. 

 Body beneath densely very coarsely punctate at sides, more sparsely 

 at middle. Upper tooth of front tibia submedian or slightly nearer 

 the base than the apex; ungual tooth median in position, its apex 

 slightly nearer the base than the tip of the claw. Length 8-10 mm.; 

 width 4.5-5.6 mm. 



Described from three examples taken by the writer at Palm 

 Springs, California, in April.
