1924] On Some New Phloeothripidce from the Transvaal 301 
Pterothorax about as wide as prothorax, sides almost parallel. 
Wings minute. Fore tarsus with a moderately long, stout tooth. 
Abdomen broad, 1.4 times as wide as prothorax. Tube 
about 0.8 as long as head, about twice as long as basal width, 
and distinctly more than twice as broad at base as at apex. 
Bristles long and pointed, those on the ninth segment somewhat 
shorter, subequal to terminal bristles, two-thirds as long as tube. 
Measurements of holotype (9): Length about 1.74 mm.; 
head, length 0.228 mm., greatest width 0.209 mm., width at 
base 0.188 mm.; eyes, length 0.052 mm., width 0.048 mm., 
interval 0.081 mm.; postocular bristles, length 0.090 mm.; 
prothorax, length 0.200 mm., width (inclusive of coxae) 0.408 
mm.; pterothorax, width 0.413 mm.; abdomen, width 0.573 
mm.; tube, length 0.180 mm., width at base 0.091 mm., at apex 
0. 043 mm.

Width (/x) 45 32 35 34 31 30 26 18 
Total length of antenna 0.50 mm. 
Female, forma macroptera. — Head concolorous with body, 
instead of yellow; eyes much larger, rounded, their width nearly 
equal to their interval; ocelli large, the anterior one situated in 
front of eyes and overhanging; pterothorax broader than pro- 
thorax; wings broad, colorless, fore pair with 8 or 9 accessory 
hairs on posterior margin; outer subbasal bristle on fore wings 
short and pointed, others three times as long and capitate. 
Male (brachypterous) . — Only slightly smaller than female 
and quite similar in general structure; fore femora greatly 
swollen, tarsal tooth much stronger, nearly triangular. 
Described from 30 females and 20 males, taken by Mr. J. C. 
Faure at Johannesburg, Transvaal, April 21, 1914, under dead 
Eucalyptus bark (No. 404). 
A true Trichothrips, with the terminal antennal segment 
pedicellate. Separable from its congeners by the coloration, the 
rather long third antennal segment, and the details of chaetotaxy.
