FALL AND COCKKRELL.

L.eptiira cockerelli n. sp.— Black throughout, moderately shining, pu- 

 bescence obscure fusco-cinereous, very short and strongly inclined on the elytra, 

 longer and erect on the prothorax. Head densely but not coarsely punctate, 

 median line finely impressed ; tempora short, slightly convergent. Antennse 

 three-fourths as long as the body {%). not at all incrassate and not obviously 

 compressed ; fourth joint very slightly shorter than the third and subequal to the 

 sixth, fifth slightly longer, eleventh one-third longer than the tenth, the con- 

 striction faint. Prothorax not wider than the head, as wide as long, apical con- 

 striction moderate, sides parallel at middle or slightly convergent to the basal 

 constriction ; hind angles laminiform but short and obtusely rounded, not more 

 prominent than the sides; base impressed before the scutellum, hind margin 

 deeply sinuate each side within the angles; disk densely rather finely punctate 

 and rather shining, a short median impunctate line before the base. Elytra 

 moderately narrowed behind, rather finely and closely punctate, apex feebly 

 narrowly obliquely truncate. Length 9.5-11 mm. 



New Mexico, Beulah (Cockerell) ; Colorado, Ouray (Fenyes). 



The described type is a S from Beulah. In this sex the fifth 

 ventral is broadly truncate emarginate, the angles slightly produced. 

 The female differs from the male in its nearly parallel elytra, which 

 in the single specimen at hand are not at all truncate at tip, the 

 slightly wider ])rothorax and the shorter antenna?, these being about 

 half the length of the body with the outer joints shorter. The fifth 

 ventral in the 9 is broadly arcuato-truncate. In form cockerelli 

 agrees very closely with crassipes, near which it should stand in the 

 table. 



lieptiira iii!«igiiis n. sp.— Eufotestaceous, elytra S(miewbat paler; surface 

 moderately shining, pubescence fine, short, inconspicuous; prothorax immacu- 

 late or rarely with two faint longitudinal discal spots ; elytra each with two elon- 

 gate marginal blackish spots before the middle, a rather broad brown discal stripe 

 from the humerus nearly to the apex, and a short subbasal inner vitta confluent 

 anteriorly with the discal stripe. Head densely finely punctate, median line 

 impressed, tempora distinctly oblique. Antennse subequal in length to the body 

 (%), or three-fifths the length (9). Prothorax finely closely punctate but some- 

 what shining, a little longer than wide, sides moderately convergent from base 

 to apex, feebly bisinuated by the apical and basal constrictions, transverse basal 

 depression well marked, median line rather strongly impressed from the middle 

 to the apical constriction, disk feebly impressed each side the middle; hind 

 angles broadly feebly laminate, not produced. Elytra slightly narrowed poste- 

 riorly, apices rounded, without trace of sinus or sutural spine. Surface veiy 

 finely and rather sparsely punctate. Length 20-25 mm. 



California, Monterey (Fuchs and Fenyes). 



In the male the fifth ventral segment is broadly rather deeply 

 arcuato-emarginate, the angles dentiform and acute ; the fifth seg- 

 ment in the female is squarely truncate.
