262 CHR. AURIVILLIUS, L. B. PROUT UND E. MEYRICK 



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. — PI. 11, F'ig. 8. — 5 24 — 25 mm. 

 Head white. Palpus a little longer even than in E. Jialosydne; \ii\\\\\^, i^* joint 

 and proximal part of 2°** each with a black-brown streak on outer side. Thorax 

 and abdomen mostly white, the latter with black-brown paired spots on i** 

 tergite, a dark patch on 2°^ (posteriorly) — 3*"'^, with a blacker central spot, 

 and single small dark posterior spots on the other tergites, the crests vestigial. 

 Femora and tibiae in part darkened, tarsi ringed; tarsal spinules prominent. 



Foreiving 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, 

 shghtly 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. — Hindwing 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 hnes indicated; postmedian 

 strong, except anteriorly, its shape as on forewing; terminal Hne 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.
