[December 
tennse about one and one-third times as long as head; segment 
3 about equal to 1 and 2 together and 1.4 times the length of 4; 
4-7 prolonged ventrallyi at apex, 4 and 7 only slightly; all bristles 
and sense cones particular!}^ short and weak. Mouth cone shorter 
than its width at base, about reaching middle of prosternum, broad- 
ly rounded at apex, tip of labrum not attaining that of labium. 
Prothorax less than one-half as long as head and (inclusive 
of coxae) about 1.6 times as wide as long, surface nearly smooth, 
with sides and the abruptly declivous posterior margin lightly 
subreticulate; midlaterals minute, all other bristles present, 
brownish yellow, knobbed and about equal to postoculars and 
coxals. Pterothorax very small, decidedly narrower than pro- 
thorax; mesoscutum transversely striate with anastomozing 
lines, becoming subreticulate at sides; metascutum subreticulate 
at sides and base, rather closely longitudinally striate elsewhere. 
Wings wanting. Legs long and slender, with femora and tibiae 
(particularly those of posterior legs) arcuate; fore tarsi armed 
with a long, stout tooth. 
Abdomen broad and heavy, fully 1.5 times as wide as pro- 
thorax. Tube less than half as long as head and about twice as 
long as basal width, which is twice the apical. Bristles nearly 
colorless, long, nearly pointed; terminal bristles brownish, about 
0.7 as long as tube. 
Measurements of holotype (9): Length 2.90 mm.; hea^, 
length 0.593 mm., width (across eyes) 0.257 mm., width at 
base 0.204 mm.; eyes, length 0.128 mm., width 0.060 mm., 
interval 0.135 mm.; prothorax, length 0.255 mm., width (in- 
clusive of coxae) 0.408 mm.; pterothorax, width 0.330 mm.; 
abdomen, width 0.638 mm.; tube, length 0.249 mm., width at 
base 0.126 mm., at apex 0.061 mm.

Total length of antenna 0.80 mm. 
^Several genera of Phloeothripidae have certain of the intermediate 
antennal segments prolonged in this way, and the teeth so formed are set 
with a series of short, sensory bristles. Various entomologists have described 
these teeth as being situated on the dorsal surface of the antennae, whereas 
they are clearly ventral in position.
