with ruddy sprinkling and with two faint subterminal dark lines crossing both 

 wings and a prominent discal lunule on secondaries. Expanse 39 mm. 

 Habitat: Truckee, Calif. (Oct. 24). 1 $. Type, Coll. Barnes. 



Similar in type of maculation to the Eastern devia Grt. but con- 

 siderably larger in size with much ruddier fringes. 



ACRONYCTINAE 



Leucocnemis obscurella sp. nov. (PI. Ill, Fig. 9). 



Palpi and head ochreous, thorax ochreous suffused with blue-gray; 

 primaries ochreous evenly overlaid with bluish gray, leaving the ground 

 color only visible partially in the terminal area where it is cut by the darker 

 veins; the only maculation visible is the orbicular and reniform spots, both 

 small, round and ochreous with a slightly deeper central dot; fringes obscurely 

 checkered ; secondaries even smoky brown with paler fringes. Beneath light 

 smoky ochreous. Expanse 20 mm. 



Habitat : Denver, Colo. 3 9 . Types, Coll. Barnes. 



This obscurely marked species is allied to perfundis but lacks all 

 indications of cross lines ; our three $ 's have only one fore-tibia be- 

 tween them but this shows a distinct claw which, combined with the 

 non-tuberculate front, seems to warrant the above generic refer- 

 ence. 



Catabena pronuba sp. nov. (PI. Ill, Fig. 11). 



Palpi and thorax gray, sprinkled with smoky, collar pale ochreous at base, 

 this area limited by a black transverse line; front pale ochreous crossed by a 

 dark line; primaries long, narrow, rather dark gray with ill-defined macula- 

 tion; a very fine black basal hair streak extending through fold halfway 

 to outer margin; t. a. and t. p. lines indicated by small dark costal blotches; 

 a dentate mark above inner margin evidently marks a portion of the t. a. 

 line; orbicular rather prominent, consisting of a very narrow decumbent white 

 oval with a central dark line ; reniform indicated by a small dark lunule below 

 and around which are some indistinct dark strigae which may form portions 

 of the t. p. line; an oblique dark shade extends inward from apex of wing and 

 below this the s. t. line can be traced as a faint white wavy line, angled inward- 

 ly above inner margin and with narrow black dashes beyond it in terminal 

 area, most prominent in fold and opposite cell. Secondaries hyaline white, 

 immaculate. Beneath primaries pale smoky, secondaries as above. Expanse 

 27 mm. 



Habitat: Jemez Spgs., N. Mex. (July 24). \$. Type, Coll. Barnes. 



The species approaches sagittata B. & McD. in wing form but 

 apart from the maculation of primaries is at once separated by the
