ence of two pairs of spurs on the hind tibise however at once sep-

Hydriomena terminipunctata sp. nov. (PI. II, Fig. 7). 



Palpi moderately long, blackish; front and thorax ochreous sprinkled with 

 black; primaries gray, slightly tinged with pale olivaceous, sprinkled and 

 banded with purplish; with the exception of slight blackish shading along 

 costa the basal space is pale, bordered outwardly by a black line which is 

 outwardly oblique from costa to middle of cell, then rather sharply angled 

 and almost perpendicular to inner margin or bent slightly outwardly above 

 vein 1 ; this line is followed by a pale band of ground color the outer edge 

 of which forms a prominent outward tooth in the cell and is then sub- 

 parallel to the basal line with a slight tooth above vein 1 ; the median band is 

 fairly broad, the inner § being purple, the outer i olivaceous-gray, a fine 

 dark line marking the division of the two colors; the outer margin of this 

 band is formed by a dark line, broad at costa and oblique outwardly to vein 

 5, then very fine, slightly waved, and almost perpendicular to vein 1 where 

 it bends outward reaching inner margin considerably before anal angle; vein 1 on 

 the outer portion of this area is rather broadly black-lined, extending at times 

 almost to anal angle; in the $ the subterminal space is rather immaculate gray 

 sprinkled with purple, bordered outwardly by a broad purple band, oblique 

 from costa to near outer margin on vein 4 and then greatly narrowed, close 

 to and parallel with margin with an inward bend in the fold; this band is pre- 

 ceded by a fine dark subparallel line more or less obsolete in lower portion 

 of wing; in the 5 this line is much more prominent, thickened at costa, the 

 remainder crenulate with a purplish blotch preceding same opposite cell; a 

 purplish apical patch and two black subapical streaks, the lower one cutting 

 the submedian purple band below vein 6; terminal area olivaceous gray with 

 veins lined on both sides by short purplish streaks; fringes pale, checkered; 

 secondaries pale smoky with a faint postmedian dark line, sharply bent on vein 

 3 to inner margin above anal angle, shaded outwardly with whitish, a terminal 

 series of pale oblong intravenular spots; fringes white, checkered with black 

 opposite veins. Beneath pale, slightly smoky with the maculation of the upper 

 side faintly visible. Expanse $ 24 mm., 9 27 mm. 



Habitat: Stockton, Utah (July). 1 6,3 9. Types, Coll. Barnes. 



The species is closest apparently to similaris Hist, (glenzvoodata 

 Swett) but much paler and the terminal pale spots on secondaries 

 seem quite characteristic. 



Hydriomena mediodentata B. & McD. 



Since describing this species from a unique and almost unicolor- 

 ous dark 9 we have received a $ from Palmerlee, Arizona; it is 

 less dark than the 9 and has an ochreous patch at base above inner 

 margin crossed by a brown perpendicular line; the median area is
