veins. — Hindwing with termen somewhat sinuous; SC? not stalked; proximal 
lines best developed at abdominal margin; postmedian and the markings beyond 
analogous to those of forewing, but with the radial spots more fully confluent, 
less outstanding. 
Forewing beneath more smoky; cell-dot large; large costal dots at origin 
of subbasal, antemedian and postmedian lines; postmedian traceable throughout, 
not angulated subcostally, marked with slight dashes on the veins; a whitish 
terminal spot between R® and M?’; terminal line and fringe as above. Hindwing 
white; cell-dot rather strong; 3 or 4 indistinct proximal lines at hindmargin; 
double postmedian and proximal subterminal brown-grey lines moderately dis- 
tinct on the veins; especially the proximal postmedian; terminal line and fringe- 
spots rather weaker than above.

13. Eupithecia(?) inepta sp. nov. — Pl. 11, Fig. 8. — 9 24—25 mm, 
Head white. Palpus a little longer even than in Z. halosydue; whitish, 1% joint 
and proximal part of 24 each with a black-brown streak on outer side. Thorax 
and abdomen mostly white, the latter with black-brown paired spots on 1° 
tergite, a dark patch on 2"4 (posteriorly) — 3°¢, with a blacker central spot, 
and single small dark posterior spots on the other tergites, the crests vestigial. 
Femora and tibiz in part darkened, tarsi ringed; tarsal spinules prominent. 
Forewing with costa shouldered near base, acute and slightly produced 
apically, termen obliquely, very feebly sinuate in anterior half; cell rather less 
than one-half; areole ample, undivided; white, slightly suffused (especially in 
the median area) with light-brown, which shade tends to form a large number 
of extremely faint, rippled lines; costal margin with a small dark area at base, 
afterwards dark-dotted; a rather large blackish cell-dot; antemedian line ap- 
parently very strongly excurved in middle (to near the cell-dot) but only dis- 
tinct at one-third costa and one-third hindmargin, at the latter developing an 
oblique dark dash; postmedian about midway between cell-dot and termen, 
slightly outbent in middle and inbent at M’, chiefly indicated by the whiter 
area which follows and by dark vein-dots or minute dashes, those on the radials 
best developed or blackest; terminal area very feebly shaded, the white sub- 
terminal line almost obsolete, but accompained proximally by large black dots 
at costa and in cellule 7 and minute or in part obsolescent ones in the other 
cellules; terminal line interrupted or almost obsolete; fringe proximally white, 
distally more brownish, with dark spots opposite the veins. — Hzudwing with 
costa strongly elongate, termen produced at SC?—R’, slightly sinuous but only 
feebly convex posteriorly; cell rather short, SC? stalked; white, in proximal 
part (except costally) somewhat shaded with light grey-brown, at termen with 
light brown; proximal part with several light-brown lines indicated; postmedian 
strong, except anteriorly, its shape as on forewing;- terminal line and fringe as 
on forewing. 
Underside with strong cell-spots, heavy costal spot at origin of ante- 
median, the lines darker than above, the postmedian strong and thick (least so 
on forewing posteriorly), even the white distal area irrorated with brown.
