17,2 Karny: Thysanoptera from the Philippines 207 
Head about three times as long as broad, broadest across the 
eyes, then a little narrowed and again somewhat dilated in the 
basal quarter, and before the hind margin distinctly collariform 
and constricted. Cheeks set with numerous strong, sharply 
pointed spines and long postocular bristles. A pair of very long 
and strong knobbed bristles occurs near the anterior ocellus. 
The anteocular processes of the head are a little shorter than 
wide, with somewhat emarginated sides. Antennse a little 
longer than head, bristles and hairs on every joint; especially 
the third and the fourth joints with a long and strong bristle, 
behind the middle on the outer (posterior), and near the apex 
on the inner (anterior) margin. Sense cones (very slender 
and hardly to be distinguished from the bristles) occur, one on 
each side of joints 3 and 4 near the apex (that of the outer 
margin of third joint in my specimen broken off near base) ; 
one normally developed on the inner margin of fifth joint, the 
outer rudimentary; sixth joint with only one sense cone on 
the inner margin; the two basal and the two apical joints with- 
out sense cones. Mouth cone broadly rounded at apex, a little 
exceeding the middle of prosternum. 
Prothorax somewhat transverse, a little dilated posteriorly, 
including the fore coxse twice as wide as long; with a sharp 
longitudinal median line; anterolateral and mediolateral bristles 
well developed, those of the hind margins still longer and stronger. 
No toothlike tubercle at the sides of prothorax. Fore coxse set 
with a few short spines and a very long and strong bristle on 
the angle. Fore femora strongly thickened, on the inner mar- 
gin with a small, blunt tubercle near the base and with a few 
short spines, on the outer with several longer ones and between 
these some that are shorter; whole surface covered with nu- 
merous spine-bearing pits; near the outer margin before the 
apex is a strong sickle-shaped bristle. Fore tibae stout, on each 
margin set with bristles and spines, especially two or three 
very long ones on the basal half of the outer margin ; the upper 
surface with a row of spine-bearing pits. Fore tarsi armed 
with a large triangular tooth. 
Pterothorax with somewhat protruding fore margins, distinctly 
narrowed posteriorly. Intermediate and hind legs relatively 
long and stout, their femora somewhat thickened, subclavate, 
set with some strong bristles. Wings clear, not narrowed in 
the middle, reaching about to the middle of abdomen; the fore 
pair are, in the basal half, provided with a pale yellowish me- 
dian longitudinal stripe, in the distal half, with a scarcely
