beyond this is a narrow white band, obscured by smoky scaling and traversed 

 by two further dark lines ; median space similar in color to basal space with 

 three pairs of darker lines, the lines of each pair tending to coalesce; a faint 

 discal dot; the outer border of this area bent in slightly opposite cell and again 

 below vein 2 and followed by a narrow white band edged outwardly by a dark 

 line and with a similar central one; terminal space dark smoky crossed by 

 a faint whitish s. t. line originating in a short white apical streak; terminal 

 black line broken at ends of veins ; fringes pale, with central dark line and 

 slight checkering oposite the veins ; secondaries whitish, sprinkled with smoky, 

 with traces of the parallel lines of primaries, the only one however that is 

 at all distinct being a post median line corresponding to the outer border of 

 the median area of primaries ; terminal dark line and fringes as on primaries. 

 Beneath rather pale smoky, sprinkled, with a broad paler outer border on 

 both wings defined inwardly by a dark line corresponding to the postmedian 

 line of upper side; white apical dash on primaries and small discal dots on 

 all wings ; fringes as above. Expanse 27 mm.

The species is very similar in maculation to elegans Grossb., 

 wrongly placed in the genus Coenocalpe as the fore tibia is clawed 

 and the front tuberculate; it is however rather paler in color and the 

 antennae are strongly pectinate, not ciliate as in elegans. We place 

 the species in Lithostege as it appears to agree structurally, apart from 

 the pectinate antennae, with the characterization of this genus.

9 . Head and thorax white with dark speckles and a blackish line across 

 the collar, abdomen ochreous ; primaries whitish, sprinkled lightly with purplish 

 gray and with the terminal area entirely this color; traces of an angled 

 basal line; t. a. line distinct, geminate, purple gray, the outer line heavier, 

 straight for a short distance below costa, then rounded outwardly, bent inward 

 in the fold, straight to inner margin with three blackish dots on outer line, 

 one just above inner margin the other two on fold and cubital vein ; t. p. 

 line purplish-gray, starting from a prominent costal dark streak, rather diffuse 

 and concave opposite cell its inner edge marked by a dark upright streak 

 representing the reniform and with dark streaks on veins 3 and 4, below vein 

 4 narrower and parallel to outer margin with three equidistant dark dots, the 

 lowest resting on inner margin ; beyond it two equidistant parallel fine purplish 

 gray lines, the inner scalloped, the outer diffuse below costa; fringes checker- 

 ed. Secondaries white with a faint smoky tinge, deeper outwardly. Beneath 

 whitish, primaries with two dark costal blotches near apex and slight smoky 

 terminal shade; secondaries immaculate. Expanse 25 mm.
