oblique, discontinued, dentate line beyond tlie disc ; diseal spot dusky, 

 distinct, very small ; an angulated very indistinct sub-basal line. The 

 wing subcostally, before the apex, irregularly sprinkled with reddish- 

 ochraceous scales ; a dusky shade spreads along the eosta at the middle 

 of the wing and extends undefinedly downwards beyond the diseal spot. 

 The ground color is a peculiar obscure dusky purplish, becoming some- 

 what dark olivaceous towards the base. The whole wing is destitute 

 of any very distinct markings, except the subterminal row of spots on 

 the nervules. 



Posterior wings dull black, testaceous along the costa, very slightly 

 pale blackish before the anal angle on internal margin; fringes whitish. 



Under surface of both wings dull grayish with a warm purplish 

 tinge, sprinkled with dusky irrorations, and with a subobsolete. subter- 

 minal series of dots on the nervules; on anterior pair the basal half 

 centrally is dusky, diseal dot white. 



Head above, and thorax, dark dusky-olivaceous. A narrow white 

 stripe margins the thoracic parts, laterally obsoletely continued to 

 base of antennae, beyond these, above the eyes, it is more distinct. 

 Palpi externally, dusky purplish-gray, terminal joints tinged with oliva- 

 ceous. Under surface of thoracic region and abdomen quite pale, dull. 

 purplish-gray ; upper surface of abdomen darker, without ornamenta- 

 tion of any kind. Legs finely scaled, like the under corporal parts in 

 coloration, narrowly margined laterally with whitish.

A peculiarly graceful dusky species, with very falcate apices of ante- 

 rior wings. The general style of coloration and ornamentation bears a 

 certain resemblance to the figui-e oi Darapsa Butus Cramer sp.. but 

 that species is evidently quite distinct. The corporal parts are some- 

 what stouter than in the other species mentioned in thi?^ paper except- 

 ing 0. Neclkus, and, perhaps, C. tcrsa.
