long transverse rows. Mandibles curved medially; apical 
tooth round-pointed and curved medially; a large anterior 
subapical tooth directed anteroventrally ; a large blunt 
medial tooth directed posteroventrally and sometimes 
covered with spinules ; teeth surrounding a denticulate 
area; anterior surface with many long slender spinules 
arranged in transverse arcuate rows. Maxillae with the 
apex paraboloidal; palp a peg with one subapical (bearing 
a spinule) and four apical (two bearing each a short 
spinule) sensilla; galea a tall slender frustum with two 
apical sensilla. Labium with a median anteroventral pro- 
jection covered with short rows of minute spinules; palp 
a low knob with five sensilla (three bearing a spinule each) ; 
opening of sericteries a short transverse slit on the end of 
the projection. Hypopharynx with numerous transverse 
rows of minute spinules. (Material studied: eight larvae 
from Java.) 
Subtribe Pheidologetini Emery 
Body hairs of two or three types; those on the dorsal 
and lateral surfaces deeply bifid, with the branches curling 
away from each other. Labrum subrectangular, with the 
ventral corners rounded. Posterior surface of labrum 
sparsely spinulose or without spinules. Mandibles as a 
whole not curved medially; the teeth not surrounding a 
denticulate area; anterior surface without spinules. Labi- 
um without a median projection. Labial palp represented 
by a cluster of four sensilla. Hypopharynx apparently with- 
out spinules. 
Genus Pheidologeton Mayr 
Short and stout; prothorax forming a stout neck, which 
is bent ventrally to a right angle; dorsal profile C-shaped, 
ventral profile of abdomen nearly straight ; diameter great- 
est at abdominal somites ill and IV. Body hairs moderately 
numerous and short. Of three types ( with intergrades) : 
(1) deeply bifid, with the branches curling away from each 
other and enlarged at the tip, the most abundant type (but 
absent from the ventral surface) ; (2) bifid, with the 
branches acuminate and nearly straight, a few on the ven- 
trolateral surfaces; (3) a few simple hairs on the ventral
