Prothorax about 1.62 times as wide as long; pronotum with minute, close, 

 transverse striae visible only under high magnification and a few scattered 

 dark bristles, the pair at the posterior angles long, stout, and dark, about 

 1.6 times as long as width of segment 2 of antenna. Pterothorax about 1.23 

 times as wide as prothorax. Wings of fore pair about ten times as long as 

 greatest subbasal width exclusive of scale, 2.45 times as long as antennae, 

 and nearly four times as long as width of head; anterior vein with a group 

 of three dark bristles in basal fourth, a group of two in second fourth, one 

 bristle at middle, and two more near tip; posterior vein with one bristle in 

 apical half. 



Abdomen with last segment about 1.3 times as long as wide, not divided 

 above; bristles very light brown, normal to the genus.

Described from one female taken by A. A. Girault at Pentland, Queens-

 The abdominal markings are distinctive. 



Anaphothrips speciosus sp. nov. 



Female (macropterous) . — Length about 1 mm. Color dark blackish brown 

 with abdominal segments 3-5 abruptly pale yellow; legs yellow, with 

 femora shaded on outer surface with dark blackish brown; antennal seg- 

 ments 1, 2, and 5-8 slightly lighter than head; segments 3 and 4 yellowish, 

 the latter slightly darker apically; fore wings nearly clear, with a brown 

 transverse band occupying second fifth; hind wings with brown median 

 vein. 



Head about 1.08 times as wide as long, about equal in length to pro- 

 thorax, narrowest at base and widest across eyes, cheeks evenly arched; 

 vertex convex and rounded ; occiput with four or five transverse anastomos- 

 ing lines; all bristles minute, subequal in length to diameter of ocelli. 

 Posterior ocelli situated just behind middle of eyes and forming a nearly 

 right angle with the anterior ocellus, which is slightly smaller. Eyes half 

 as long as head, prominent, protruding, and about two-thirds as wide as 

 their interval. Antennae nearly 1.9 times as long as head, eight-segmented, 

 segment 6 not divided by a subapical suture; segment 3 with a forked 

 trichome on dorsal surface, segment 4 with a similar one on ventral surface. 

 Mouth cone reaching three-fourths across prosternum; maxillary palpi 

 three-segmented . 



Prothorax about one and one-fourth times as wide as long and about 

 equal in length to head; surface smooth, and with a few minute bristles; no
