1924] On Some New Phloeothripidce from the Transvaal 297 
dorsal surface of the head4 Ocelli exactly equidistant, pigment 
red. Antennae almost exactly as figured in the original descrip- 
tion of the genotype, but more slender (see measurements) and 
without infundibuliform bristles at base of segment 2 and apex of 
segment 3; sense cones as in figure of that species. Mouth cone 
acute, about attaining posterior margin of prosternum, labrum 
acutely pointed. 
Prothorax somewhat more than half as long as head and 
(inclusive of coxse) nearly 2.4 times as wide as long, surface finely 
granulate; all usual bristles present, broadly dilated, fan-like, so 
transparent as to be easily overlooked; posterior plate at hind 
angles with two bristles, instead of one, the posterior bristle the 
largest on prothorax. Pterothorax wider than prothorax, sides 
subparallel for half their length, then roundly converging to base 
of abdomen. Wings of fore pair sharply constricted near middle, 
where there is a short median thickening; basal portion without 
fringe on anterior margin, but with about 8 minute hairs in outer 
portion of posterior margin; distal portion of wing rather spar- 
sely fringed, without accessory hairs; entire wing roughened 
and lightly but distinctly reticulate; subbasal bristles set close 
to base of wing, minute, expanded. Legs short, fore and hind 
femora swollen, fore tarsi with a long, slender, hooked tooth; leg 
bristles mostly expanded apically. 
Abdomen distinctly broader than prothorax. Tube nearly 
two-thirds as long as head, unusually slender, more than three 
times as long as basal width which is hardly twice the apical, 
slightly widened at base, sides slightly converging apically. 
Bristles broad, nearly clavate, almost transparent, the latero- 
ventral pair on segment 9 longer and pointed; terminal bristles 
yellowish, hardly twice as long as tube. 
Measurements of holotype (9): Length 1.55 mm.; head, 
length 0.252 mm., width 0.221 mm., width at base 0.182 mm.; 
^In the original description of S. maculatus (Hood), Entomological 
News, XX, 1909, p. 250, the eyes are said to be reniform, and are so shown 
in the figure given on page 251. As the wings of the unique type had not been 
spread, and as the coloration was so dark as to make difficult any detailed 
study of the chitinous exoskeleton, the writer ventured to clear the specimen 
in potassiu'm hydroxide and remount it; and subsequent study shows the 
eyes to be broadly rounded posteriorly, and not at all reniform. Only the 
type is known.
