3. Costal cell with two hyaline spots; cell 
R with a small round spot just behind 
the r-m cross vein; no wedge-shaped 
hyaline mark on costa] margin just 
beyond stigma; mesopleura yellow 
(Fiji) . . . mesopleuralis (Malloch) 
Costal cell with one hyaline mark; no 
spot in cell R; a wedge-shaped spot 
just beyond stigma; mesopleura 
black 4 
4. Mesonotum densely brownish-gray 
pollinose, with three dark vittae; 
vein R4+5 bristled only to the r-m 
crossvein (New Guinea) 
taylori (Malloch) 
Mesonotum entirely shining black; 
vein R4-1-5 setulose nearly its entire 
length (New Guinea) . . .erebia (Hering) 
5. Wing markings as in Figure 29 a. The 
black margin at the wing apex con- 
tinuous with the vertical black band 
through the wing; the hyaline mark 
in the apical portion of the wing not 
inverted Y-shaped and compara- 
tively broad, extending from the 
middle of cell R5 to near lower apex 
of cell M2; cell M2 almost all hyaline 
at its apex; the hyaline transverse 
markings toward middle of wing ex- 
tending into the apical portion of 
cell 1st M2 on the top as well as the 
lower margin; the black coloration 
extending to the apex of cell M4 in 
the middle and fills all of this cell 
except the lower edge (Australia) 
australina n, sp. 
Wing markings as in Figure 30. The 
black margin at the wing apex not 
continuous with the black vertical 
band; the hyaline mark in apical por- 
tion in the form of an inverted Y and 
comparatively narrow, extending 
from lower portion of cell R5 to 
about middle of cell M2. The hyaline 
"arms” of the Y-shaped mark about 
equal in width to the oblique, black 
streak which sets off the Y, cell M2 
almost all black at its apex; the hya- 
line transverse markings not extend- 
ing into cell 1st M2 so this cell is 
entirely black; the black markings 
not extending to the margin in cell 
M4, except at the upper corner, and 
the lower two-fifths of this cell hya- 
line (Solomon Islands) 
apicifasciata (Malloch) 
Hendelina australina n. sp. 
Fig. 29 a-c 
This species appears to be more closely 
related to H. apicifasciata (Malloch) (Fig. 30) 
than to any other known species. It is easily 
separated by the differences in the dark pat- 
tern in the wings as pointed out in the above 
key. 
MALE. Chiefly black species. Head: Yel- 
lowish to rufous, concave portion of the 
occiput black. Front about two times longer 
than wide, and with three pairs of inferior 
fronto-orbital bristles and two pairs of superi- 
or ftonto-orbitals. Ocellar bristles moderately 
developed and slender. They are about half 
as long as the superior ftonto-orbitals. Face 
silvery pubescent, median portion flat and 
straight, sides rather deeply grooved. Anten- 
nae yellowish, third segment about two times 
longer than wide. Thorax: All black except 
for the yellowish humeri. Pleura subshining, 
mesonotum and scutellum grayish pollinose. 
Dorsocentral bristles placed distinctly pos- 
terior to the anterior supra-alar bristles. The 
scutellum has four strong bristles and a few 
small marginal hairs. Halteres black. Legs: 
Front pair all yellow except for slight brown- 
ish discoloration on the outside of each 
femur. Middle and hind femora and the 
bases of the tibiae black, except for extreme 
tips of middle femora which are yellow. 
Middle and hind tarsi and apical three-fourths 
of the tibiae yellow. The spurs of the middle 
tibiae are well developed and are about half 
as long as the basitarsi. The front femora 
have a row of moderately long bristles evenly 
spaced along the exterior ventral portion. 
Wings: (Fig. 29 ai) Basal half, excepting anal 
and auxiliary lobes and posterior one-third
