178 SEINOSUKE UCHIDA : 
segment broad, as long as the second or fifth segment, the third and fourth 
segments about equal and half the length of the other segments. Eyes large, 
but indistinct, each with a short spine on its posterior margin; another short 
spine behind eye on lateral margin ; temples rounded and more expanded than 
those of G. megalocephalus, bearing two long, strong, hairs and two very fine 
prickles ; posterior parts slightly expanded, terminating in two rounded projec- 
tions, each bearing a short prickle ; occiput sinuous, occipital margin nearly 
straight. Dorsal surface of head with four short hairs, two shorter ones on 
the clypeus and the other two near the bases of antenne. Ground colour of 
the head pale yellowish; frontal band yellow, terminating in reddish brown 
antennal blotch, in front of each antenna; temporal bands narrow, clear 
yellowish, broadening posteriorly ; occipital band distinct, with two dark 
brown occipital blotches. 
Prothorax short, narrow, trapezoidal; anterior margin concave ; posterior 
margin slightly convex; lateral margins diverging posteriorly ; with pale, 
indistinct submarginal bands; lateral angles slightly protruded, bearing a 
longish hair. Metathorax triangular, with apex forming an obtuse angle on 
the abdomen ; anterior margin straight; lateral angles rounded, much pro- 
truded, each bears two long, pustulated hairs; and a short hair on the dorsal 
surface of each angle; anterior lateral margins with broad yellowish marginal 
bands which end in round, reddish brown blotches. Legs short, paler than 
the body, with a few spines. 
Abdomen broadly elliptical; widest at third and fourth segments; the 
first segments longest at side but short in middle, due to the backward pro- 
jecting angle of the thorax; other segments almost equal in length ; posterior 
angles of segments not protruded, bearing one to three long hairs, except on 
the first segment; segment 1 with a hair, fsegments mz and ıv with two, 
and segments v-vII with three hairs; the last segment broadly rounded, 
with a slight emargination, bearing six long and several short hairs. 
Dorsal surface of the abdomen with two rows of short hairs on the median 
portion of segments I-vIr and a row of long hairs behind each spiracle on 
segments II-vI. Ground colour of the abdomen pale yellowish; lateral 
marginal bands very narrow, clear yellowish; bending inward along the 
posterior margins of the preceding segment and ending in darker, rounded
