Geometridae of the Anjentme Bepuhlic. 237 
clouding which follows; a broad, diffuse, dark cloud from costa 
before one-third, very oblique to middle of wing, thence bent back 
to inner margin, but becoming narrower and more indistinct ; some 
rather dark shading in the central area, more brown-tinted tlian the 
other markings; marginal area broadly darkened, the pale sub¬ 
terminal line barely traceable; in addition, some characteristic 
blackish-fuscous vein-marks, namely : an oblique line from cell-spot 
along SC^ to apex of areole; and a figure slightly recalling, on left 
wing, the Hebrew letter tzaddi (placed sideways), formed by con¬ 
nected markings at the origin of and the medians. Hind wing 
and undersurface pale brownish grey without markings. 
Cacheuta, January 12, 1904 (W. M. Bayne). Type in 
coll. L. B. Front, 
From the entire structure and aspect of this species, I 
feel scarcely any doubt it is a Lithostege (probably rather 
nearly related to L. pax), though it is unfortunate that the 
legs are lost, and that the J is unknown. The double 
areole is broad, stalked with SC^“^, and following 
strongly the peculiar curvature described under the pre¬ 
ceding species; in the hindvving SC‘^ and R^ are long- 
stalked, from near and somewhat curved. 
Neochesias (Prout), nov. gen. 
Face with horny prominence, short-scaled; palpus moderate, 
rather .stout, rough-scaled; tongue present ; antenna (d) slightly 
thickened, tapering, pubescent. Thorax scarcely hairy beneath ; 
femora glabrous ; foretibia very short, with strong apical claw ; 
hindtibia not dilated, with four well-developed spurs. Frenulum 
present. Forewing long and narrow, costa slightly arched, apex 
rounded, distal margin very oblique, tornus rounded ; cell over one- 
half, discocellulars nearly vertical; areole double, ample ; SC* from 
middle of outer areole, SC^ stalked with SC^'^ from its apex, R* 
from about two-thirds of its lower margin, M* from near R^, 
from very near M*, strongly curved, running in direction of tornus for 
about one-third, parallel with M* for about two-thirds ; R^, M* and 
thus forming an irregular trident ; submedian area ample. Hind¬ 
wing ample, apex somewhat produced, yet rounded, distal margin 
slightly gibbous between R^ and IVP, faintly sinuate inwards above 
and below the gibbosity ; cell slightly over one-half, very broad, 
DC parallel with termen for two-thirds, then oblique outwards ; C 
and SC diverging widely near base, anastomosing from beyond one- 
third to three-quarters of cell; SC^ connate or short-stalked with
