PACIFIC SCIENCE, Vol. V, July, 1951 
presence of a basal white patch or band on 
segment IV of the hind tarsus. No definite 
character for the separation of the larva of 
ahadsantosi and the larva of sherki has been 
found. All characters examined seemed to 
show sufficient intergradation to render them 
useless for positive identification. Conse- 
quently, it seems likely that sherki represents, 
at the most, only a subspecies of ahadsantosi. 
As pointed out in the type description, the 
larva is polymorphic.

Adult described by Knight (1947^: 647) 
and larva by Edwards and Given (1928: 343), 
both from Malayan material. The following 
larval description is based upon two Philip- 
pine specimens and constitutes the first record 
of this species in the Philippines. No adults 
were taken. 
LARVA: Head: Antenna slender, a few small 
spicules present; antennal hair double, in- 
serted just beyond middle. Mouth brush with 
prominent comb-like tips. Hair 4 double, 
small; 5 and 6 with 3-4 branches; 7 with 3-5; 
8 single; 9 double; 12 with 3-4; 13 single; 
14 with 1-2; 15 with 3-4; 17 with 3-8; 18 
with 1-2; 20 with 2-4; hairs 4, 5, and 6 are 
all in a straight line. Mentum with 11-13 
lateral teeth. Thorax: Pro thoracic hair 1 with 
3 branches; 2 with 1; 3 with 3; all rather large 
and borne together on a sclerotized plate. A 
stout spine occurs at the base of the pleural 
hair tufts. Hair 1 of the mesothorax single, 
stout, darkly pigmented; hair 7 of metathorax 
with 4 branches, each short, very stout, darkly 
pigmented, and barbed. Abdomen: Dorso- 
lateral hairs on I and II double. Lateral hairs 
on I and II single; on III to VI double, once 
triple. Pentad hair 1 with 2-3 branches; 2 and 
4 single; 3 with 4-7; 5 with 2-4. Comb with 
14 to 19 large scales in a patch or double row, 
each scale pointed and fringed laterally. 
Segment VIII and anal segment ventral to 
anal plate pilose. Siphon incomplete basally, 
with an attached acus, index 2. 4-3.0; 9-11
