PACIFIC SCIENCE, VoL VI, April, 1952 
With assoc, larval and pupal skins. Ter- 
minalia separated. 
DISTRIBUTION: Specimens examined. Type 
series. Samar: Shohoton Springs, inland on 
Basey River. 
Unknown outside the Philippines. 
DISCUSSION: In the type description of this 
species it was stated that arboricolus was dis- 
tinguishable from the type description of 
pseudalbolineatus Brug only on the basis of 
the markings of the third hind tarsal segment 
of the female. Since that time the senior 
author has had the opportunity of examining 
the type male and the allotype female of 
pseudalbolineatus in the British Museum. They 
were found to differ further from arboricolus in 
possessing an area of broad white scales on 
the lateral margin of the scutum just before 
the level of the wing base. The hind tarsi of 
the type male had the basal marking on I-II 
occupying about one fifth of the segment, 
and on III between one fifth and one fourth 
of the segment; in the female the basal mark- 
ing on I occupies one fifth of the segment, 
on II one fourth, on III about seven eighths, 
one pale lateral scale on IV ; none of the tarsal 
bands is complete medially. The scaling of

the scutellum, apn, and ppn wd.s largely similar 
to that of arboricolus. No differences in male 
terminalia were noted. 
This species is closely similar to laffooni in 
the adult stage, differing most noticeably 
from it in the absence of broad white scales 
on the lateral margin of the scutum.

DISTRIBUTION: Specimens examined. U.S. 
N.M. Mindoro: 1 male, 1 female, 1 set assoc, 
skins, 2 larvae, Labangan River, nr. San Jose 
(Ross). 
Unknown outside the Philippines. 
DISCUSSION: The adult of this species may 
be distinguished from the other members of 
the albolineatus group by the combination of 
having all three scutellar lobes largely white- 
scaled and the median scutal stripe extending 
posteriorly to the scutum.

LARVA: Several larval skins have become 
available since the publication of the type 
description of this species. The larva is ap- 
parently indistinguishable from albolineatus 
Type B larva, except that all ventral brush 
elements are borne on the barred area.
