46 H. C. FALL. 



Described from two specimens in the writer's collection, the 

 type from Placer Co., California; the second and smaller 

 specimen from Ormsby Co., western Nevada, collected by C. 

 F. Baker. 



In general form and size sierra is perhaps nearest levicoxa, 

 but the punctuation is much coarser than in the last-named 

 species, the hind coxal plates are normally punctate, the 

 mentum is different as indicated in the table, and the ungual 

 tooth is more apical in position. 



32. D. parallela n. sp. 



Elongate oblong, parallel, dark rufotestaceous, moderately shining, 

 the minute alutaceous ground sculpture discernible on the thorax, 

 and as usual better marked on the elytra. Summit of mental declivity 

 with row of erect setae but without distinct elevated line. Front and 

 clypeus in same plane, the former without post-clypeal convexity or 

 impressions; clypeal suture posteriorly arcuate at middle; margin of 

 clypeus broadly arcuato-truncate with merest trace of sinuation at 

 middle; punctuation of head moderately close, denser on the clypeus. 

 Prothorax four-fifths wider than long, sides parallel in basal half with 

 or without slight sinuation posteriorly; punctures moderately fine, 

 separated by about twice their own diameters at middle, closer at 

 sides; apex without marginal line; angles not impressed, the front ones 

 scarcely prominent, the hind ones rectangular. Elytra parallel, a 

 little less than four times as long, as the thorax; discal costae distinct, 

 not elevated, intercostal spaces sparsely confusedly punctate, the first 

 about three times the 'width of the sutural interspace. Metasternum 

 and abdomen finely sparsely punctate at middle, closely and more 

 coarsely at sides. Upper tooth of front tibia median in position; hind 

 thighs punctate at middle; ungual tooth at about the apical third, large, 

 obliquely truncate, its tip nearly twice as far from the base as from 

 the end of the claw. Length 11£ mm.; width 5£-5§ mm. 



The type of this species was taken at Dripping Spring, 

 Organ Mountains, New Mexico, April, 1898 (Cockerell). A 

 second example from Los Pinos, Colorado (C. F. Baker), is 

 in the National Museum collection. 



This is one of the very few species in the genus in which 

 the length exceeds twice the width. 



33. D. obscura Lee. 



Moderately robust, slightly wider behind, usually dark red brown, 

 but varying from rufotestaceous to piceous, shining, elytra finely 

 alutaceous, head and prothorax scarcely or barely visibly so. Men-
