distinct, and that the true hoUcmani Grt. is a very dark and very rare 

 form. 



Oncocnemis gerdis, new species. 



Head and lower half of collar chocolate-brown, a narrow black line 

 bordering the dark part of collar. Thorax and primaries bluish gray with 

 black powderings, upper half of collar a little creamy in tinge. Primaries 

 with the markings neat, slender, black. T. a. line single, continuous, a little 

 irregular, but as a whole nearly upright. T. p. line single, continuous, out- 

 wardly oblique to vein 6, there forming almost a rectangle, with an inward bend 

 to vein 4, then slightly incurved or nearly upright to the inner margin. There 

 is no s. t. line. Claviform an ovate loop of good size, black ringed, con- 

 colorous. Orbicular small, round or nearly so, with a black central dot. 

 Reniform nearly upright, black ringed, of good size, the upper and lower 

 angles touching the t. p. line so that the angle of that line forms a roughly 

 trigonate inclosed area. There is a black streak at base which does not quite 

 reach the t. a. line. A black streak extends from the outer border of orbicular 

 through the reniform, crosses the t. p. line just above the angulation, and 

 extends to the outer margin ; but abruptly narrowed just before, the final 

 connection being formed by a narrower streak. Small interspaceal streaks 

 through the terminal area to the outer margin. A black interrupted terminal 

 line. Secondaries white, with a partial series of blackish terminal lunules 

 toward the apex. Beneath white ; primaries with the disc powdery and the 

 long discal streaks obscurely reproduced ; secondaries blackish powdered 

 along the costal margin only.

Two male examjjles in fair condition. This is a sHght species, 

 clearly yet inconspicuously marked, and allied to my scmicoUaris in 

 general habitus. 



Oncocnemis intruda, new species. 



Head, thorax and primaries bluish gray, with a strigate appearance as 

 a whole. Head tending to creamy white in front, and the collar to the same 

 at extreme base. Collar with a narrow black line below middle, above it 

 a diffuse whitish band and the tip also is whitish. Patagia and thoracic disc 

 strigate with blackish and tending to dusky submargins. Primaries strigate, 

 the ordinary transverse maculation barely traceable. T. a. line marked by a 

 black dot on costa, and below that only vaguely indicated. T. p. line black 

 marked on costa, and again traceable below vein 3, where a few paler scales 

 may emphasize the narrow dusky markings. S. t. line broken, consists of a 

 vague oblique shade inward from apex to vein 6 ; outwardly a little paler, 

 inwardly a little darker than ground ; on veins 3 and 4 obscure outward 

 dents are traceable, and below that point the line becomes conspicuous,
