so distinctly darkened; no supernumerary cross veins in cell R, 
and petiole of cell M, longer than the cell; ovipositor with the 
valves long and slender. 
_ MINDANAO, Bukidnon Subprovince, Tangcolan (Baker). The 
allotypic female has been returned to Professor Baker. 
Eriocera mindanaocénsis is related to E. ferruginosa van der 
Wulp (Sumatra and Java). In the latter species the antennal 
flagellum is light colored, the femora and tibiz are yellow with 
dark apices, and the abdominal tergites are margined laterally 
with dark brown. ‘ 
Eriocera perennis polillensis subsp. nov. 
Female.—Length, about 22 millimeters; wing, 16.8. 
Differs from typical Eriocera perennis Osten Sacken, as fol- 
lows: The first scapal segment of antenne is gray pruinose 
like the head. Mesonotum shiny black. Legs with the femora 
dark brown, the tips black. Wings dark brown, the proximal 
end of cell 1st A pale; cell 2d A not pale at base. Petiole of 
cell M, longer than the cell. Abdominal crossbands on tergites. 
2, 3, and 4 only; segment 5 entirely dark. 
POLILLO (Edward H. Taylor). Type returned to Professor 
Baker. : 
Eriocera perennis subcostata subsp. nov. 
Female.—Length, about 17 millimeters; wing, 12.3. 
Differs from typical Eriocera perennis Osten Sacken, as fol- 
lows: 
Rostrum and palpi black. Antenne with the basal segment 
gray ; second scapal and basal two flagellar segments yellow; ter- 
minal flagellar segments black. Head clear light whitish gray, 
the gene becoming infuscated. 
Mesonotal prescutum grayish brown with three clear-cut, con- 
fluent black stripes; remainder of thorax velvety black. Wings 
dark brown; base of wing broadly bright yellow, this color 
including about the basal third of cells C and Sc, and the cells 
proximad of arculus; basal fourth of cell 2d A pale; a conspicuous 
paler yellow crossband before the cord, extending from R into 
the base of cell Cu,; cell Sc paler than the remainder of the 
disk, connecting the basal and discal pale areas ; veins black, 
yellow in the pale areas. Venation: Sc, ending opposite mid- 
length of the basal section of R,; r about one and one-half times 
to twice its length beyond the fork of R,+,; inner end of cell 
1st M, nearly square; petiole of cell M, shorter than cell; basal 
deflection of Cu, at midlength of cell 1st M.,.
