[February 
tube darkened with brown; extreme tip of tube light gray; 
abdominal segments 3-8 with a dark brown transverse band on 
upper surface near base; antennal segments 1 and 2, and basal 
half of segment 3, yellow and concolorous with head, remainder 
of antenna dark blackish brown except for the yellowish pedicels 
of segments 4 and 5; hypodermal pigmentation orange, opaque. 
Head with two, more or less evident, setose lateral tubercles 
just behind eyes. Fore tibia produced at lower, inner surface of 
apex to form a flattened, obtuse spur which is about one-third as 
long as width of tibia; fore tarsus with a large, straight, acute 
tooth. Tube 0.75 as long as head. 
Male (apterous). — Much like female, but with the two 
lateral tubercles just behind eyes well-developed and usually 
very prominent. Fore tibia with an acute, additional projection 
on inner surface of apex, directly above the flattened, obtuse 
spur; fore tarsus with the tooth longer than width of tarsus. 
Trinidad; C. B. Williams; from dead branch of Lager s- 
troemia infested with Bromeliads, and from bamboo. 
The form of the head is suggestive of T. flavicauda Morgan. 
It is the only species of the genus with strongly armed fore tibiae. 
Eurythrips collaris sp. nov. 
Male (macropterous). — Length about 1.1 mm. Color 
blackish brown with purple subhypodermal pigmentation; 
legs paler, mid and hind tibiae and all tarsi, pale yellow, fore 
tibiae shaded with brown. Antennae with basal half of segment 
3, basal third of 4, and basal fourth of 5 pale yellow. Vertex 
sharply conical. Antennae long and slender, all segments elon- 
gated. Mouth cone long, fully attaining posterior margin of 
prosternum. Bristles long, knobbed; prothorax with anterior 
angulars wanting, all others present, anterior marginals shortest. 
Fore tarsus unarmed. Wings slender, sparsely fringed, 2 or 3 
accessory bristles. Tube very much shorter than head. 
Trinidad; C. B. Williams; from dead tree in forest. 
The only species of the genus without long bristles at the 
anterior angles of the prothorax.
