QUEENSLAND. 
By J. Douctas Hoop, Washington, D. C. 
Kleothrips acanthus, new species. (Pl. VIII, figs. 1-4.) 
Male (macropterous).—Length about 7.3mm. Color dark blackish brown, 
with the intervals between the thoracic plates and ill-defined patches on 
sides of basal and intermediate abdominal segments, bright red; femora 
dark blackish brown, paler at either end; tibie of fore pair bright 
yellow, narrowly darkened along the entire inner and outer surfaces; in- 
termediate and hind tibie yellow at extreme base and in distal half, the 
intervening portion blackish brown and paler distally; tarsi bright yellow, 
pulvilli nearly black; wings clear, with a pale yellow median streak; an- 
tennz yellow, with the two basal and two apical segments blackish brown 
and the intermediate segments darkened apically, segment 3 dark in apical 
seventh, segment 4 dark in apical third, 5 in apical two fifths, and 6 in 
apical two thirds. 
Head about four times as long as width across eyes, sides nearly straight 
and converging to just behind eyes, the width of the head at this point 
being 0.65 the basal width; produced portion of head about as long as 
width across eyes, sides slightly concave and converging tio base; dorsal 
and lateral surfaces of head transversely striate and with about six pairs 
of prominent lateral bristles in addition to numerous smaller ones; post- 
ocular bristles longer than eyes and pointed, their bases slightly closer to 
eyes than the length of the latter; a second pair of similar bristles about 
midway between postoculars and base of head, less widely separated than 
postoculars; postiocellar bristles three fourths the length of postoculars: 
anteocular bristles similar to and of the same length as postoculars. Eyes 
very prominent, bulging, about 0.18 as long as head, usually slightly nar- 
rower in dorsal aspect than their interval, and slightly longer on dorsal 
surface than on ventral. Ocelli of posterior pair distinctly larger than 
anterior ocellus and situated slightly in front of middle of eyes; anterior 
ocellus situated slightly behind middle of produced portion of head. An- 
tenne (Pl. VIII, fig. 4) about 1.48 times as long as head, very slender, 
length and width of each segment given below under “ Measurements” ; 
segment 6 slightly prolonged on ventral surface at apex; sense cones short, 
slender, and pointed. 
Prothorax about 0.32 as long as head and (inclusive of cox) about 1.65 
times as wide as long, surface smooth; all usual bristles present, pointed, 
the two pairs at the posterior angles longest, the anterior angulars arising 
from near the middle of the dorsal surface of a prominent, acute, for- 
wardly-directed tooth arising from the notal plate. Wings of equal width 
throughout, the fore pair with about fifty accessory hairs on posterior
