Trentepohlia septemtrionalis is the most northerly species

apicalis (Brunetti) of British India, which differs in the size, 
body-coloration and, especially, the coloration and venation of 
the wings.

with a narrow, dark brown median line that is narrowed behind; legs 
brownish yellow; wings light yellow, the wing-tip narrowly darkened; 
cord and inner end of cell /s¢ M2 narrowly darkened; 7 at the tip of Ri; 
cell M, present. 
Female—Length, 9 mm.; wing, 8.2 mm. 
Rostrum and palpi dark brown. Antennze with the first scapal 
segment dark brown; remainder of the antennz conspicuously and 
abruptly light yellow. Head dark brown, conspicuously silvery

wing-tip narrowly margined with dark brown, this color extending from 
cell 2nd R, to cell R;, and thence more narrowly and less distinctly to 
cell M3; narrow and indistinct brown seams at the origin of Rs; along 
cord and outer end of cell 1st Mz; forks cf Rois and Mi4.; stigma appear- 
ing as a narrow seam along r and the tip of Ri; veins yellow, darkened in 
the infuscated areas. Venation: Sc long, Sc. extending to about 
opposite one-half to two-thirds Ro;y3, Sc much longer than Sa; Rs 
moderately long, nearly twice R43, strongly angulated at origin; r at 
the tip of R,; inner ends of cells R3, Rs and 1st M2 nearly in alignment; 
petiole of cell M, a little shorter than the cell; cell 1s¢ Me rectangular, 
widened distally; basal deflection of Cm shortly beyond midlength of 
cell 1st Mo. 
Abdomen yellowish testaceous.
