of 2 and pedicels of 4-6 slightly paler, 3 yellow in basal half, remainder 

 brown. Mouth cone narrowly rounded at tip, reaching three-fourths 

 across presternum, labrum not surpassing labium. 



Prothorax about 0.9 as long as head and (inclusive of coxae) not quite 

 1.9 times as wide as long; pronotum smooth at middle, margins with strong 

 anastomosing lines; median thickening short; all usual bristles present, the 

 anterior marginals minute and pointed, others short, stout, capitate, pale 

 in color, and from one-third to one-half as long as eyes. Wings broad, the 

 fore pair without accessory hairs on posterior margin and with the three 

 subbasal bristles short, pale, and capitate. Fore tarsus with a strong 

 curved tooth longer than half the width of tarsus. 



Abdomen of normal form and structure. Tube equal in length to head 

 and 2.3 times as long as the basal width, which is 2.3 times the apicaL sides 

 straight. Abdominal bristles rather short, capitate, those on segment 9 

 about half as long as tube; terminal bristles three-fourths as long as tube.

Described from two females taken by sweeping in forest, at Brooklyn, 

 New South Wales, November 1 and 9, 1914, by A. A. Girault. 



Easily known by the brown wings and the absence of interlocated hairs 

 on the posterior margin of the fore wings. 



Teuchothrips badiipennis, sp. nov. 



Female (macropterous) . — Length about 1.7 mm. Color dark blackish 

 brown or black, with mid and hind tibia} brown, and distal ends of fore 

 tibiae yellow; antennae with segments 1, 2, 7 and 8 concolorous with head, 

 2 yellow at apex, 3-6 lemon yellow, 4 infuscate in apical third, 5 in apical 

 half, and 6 in apical three-fifths, this infuscation darkest on sides of seg- 

 ments; wings brown, the fore wings darker than hind ones and slightly 

 paler at apex and in the region of the three subbasal bristles; hind wings 

 paler in anterior half and with median vein darker. 



Head about 1.2 times as long as wide, entire dorsal surface distinctly 

 reticulate with anastomosing lines; cheeks gently arched, slightly converg- 

 ing to eyes and base of head; vertex not produced nor overhanging, the 

 anterior margin straight and vertical; postocular bristles capitate, about
