SCALY WINGED OCOPHKOGNATHA. 101 
orange yellow glass beads ; the distance of the anterior ocellus from 
one of the posterior ocelli is equal to the space between the latter and 
the eye-border : the ocellar triangle is moderately flat, the angle at the 
apex being about 120°. Eyes brown-black, pubescence extremely 
short and very delicate. Antenne relatively long, thin, approxi- 
mately equal to the length of the fore wing; pubescence 
moderately long and tolerably compact ; black-brown, the two basal 
joints brown; the antennal flagellum has 19 joints (complete) having 
the following lengths in millims. 0°15, 0°14, 0°16, 0°14, 9-1, 0-1, 
0:08, 0:09, 0:09, 0°08, 0:08, 0:09, 0:09, 0:09, 0:09, 0-08, 0:07, 
0-07, 0:07, 0:07. Maxillary palp (fig. 99) brown, end joint dark brown. 
Thorax dark brown, mesonotum covered with brownish black 
scales, which mostly give a greenish lustre, certain of them frequently 
reddish. Legs evenly yellow-brown, femoral apices brown above. 
The setz of the hind tibie relatively short and scanty. Scales of 
the femora and tibie dull yellowish with silken lustre. The 
length of the anterior tibia is 0-48 mm.; of the middle tibia 0-6 
mm., of the posterior tibia 0°96 mm. The lengths of the tarsal 
joints in the fore foot are 0:24, 0-06, 0-07 mm.; in the middle foot 
0:25, 0:06, 0°07 mm.; in the hind foot 0°37, 0-08, 0-08. The ratio 
of the hind tarsal joints is therefore 48: 1: 1. The first hind 
tarsal joint with about 14 ctenidiobothria. Ciaws (fig. 76) very 
large and slender, tooth before the apex stout and acute ; empodial 
appendix jong and setiform. 
Membrane of fore wing faint brownish gray hyaline; pterostigma 
rather narrow (fig. 88); m, enters the wing apex. The scaling is 
brownish black, with deep green metallic lustre: certain scales give 
also frequently a deep red metallic lustre. Marginal hair moderately 
long, black, with green metallic lustre. Hind wing hyaline, veins 
pale brown. Radial cell, R, relatively broad. Marginal hair long, 
pale brownish. Membrane intense red violet, iridescent red to 
golden, at the wing base iridescent green to blue. | 
Ground scales (fig. 89 gs) spatuliform, end broad and straight- 
cut or very faintly and shallowly emarginate: angles rather sharp. 
Cover scaies (ds) similar, hut much tonger. 
Length of fore wing 2°3 mm.; wing expanse 54 mm.
