dorsal half of whorls golden-brown, ventral half black-brown; palpi 
black-brown, with 5, more or less distinct, yellow or yellowish-white 
bands and dense, golden hairs on apical segment, 3-jointed, the second 
13 times as long as third, the first 5 times length of second and 
with a median joint-like constriction and an apical tumescence. Thorax 
marked as in $. Abdominal segments yellow dorsally, the second to 
sixth having each a median, hour-glass mark of black scales ; seventh with 
an obeuneate, black spot, eighth banded sub-apically with black; second 
to seventh tergites marked on margin as in ?; ventrum, including tufts, 
as in . Legs exactly similar to those of ?. Ungues of fore and mid 
legs unequal ; the larger, bidentate, its basal tooth lateral and spine-like ; 
smaller unidentate, nearly straight. Wings similar to those of 2, but all 
markings much paler; broad, brown median band extends to Vein IT 
only. Apex of costa pale-yellow, with 4 brown, interrupted spots; mid 
costa with 6. There is slight variation in the markings on dorsum 
of abdomen in both sexes, a tendency to confluence being seen in some. 
Length of d 4.5 millimeters, length of wing 2.75 millimeters. 
‘Necros Occrpentat, P. T., Bago, at Mailum on Hacienda “ Louisiana,” 
150 m. and on Siva-Siva Peak, Canloan Volcano, 700 m. (Banks, Coll.). 
Time of capture, 17-24 June, 1906, between buttresses of large lauaan 
trees (Amsoptera thurifera Blume). 
Types of do and 2, No. 6066 in Entomological Collection, Bureau of 
Science. 
This species is affectionately dedicated to my faithful friend, Sefor 
Don Juan A. Araneta, of Bago, Negros Occidental, in recognition of his 
lively interest in scientific investigation. 
The general pattern of F. aranetana is quite similar to that of F. 
poicilia Theobald, but the coloring distinguishes it at once, while the 
abdominal and wing markings in both d and 2 serve to separate it from 
PF. flavipennis Giles, the only other species with which it might, upon 
first sight, be confused. This species is apparently purely sylvan,* 
individuals being found only in the spaces between the buttresses of large 
forest trees, resting upon the bark, the color of which they appear to 
simulate to a certain extent, so that it is very difficult to detect them, 
unless one smokes them out or searches for them en profile—i. e., by 
glancing along the surface of the buttress. 
All attempts at causing them to bite were futile and nothing is known 
of their life history except that they breed in the water in the axils of 
banana leaves. They are by no means abundant. They are not active, 
soon alighting after being disturbed. Their discovery was due to a 
chance whiff of smoke blowing into their retreat. 
* Since the above has been written a specimen of the same insect was bred from 
water in the axils of banana leaves at my house in the city of Manila.
