By J. Douglas Hood 
University of Rochester, Rochester, N. Y. 
Through the kindness of Dr. C. P. Alexander, it has been

Eurythrips amplus sp. nov. 
Female (macropterous) .- — Length about 1.5 mm. (dis-

sides of head and pterothorax and in distal portion of abdo-

of V-VII, in proximal fourth and distal two-fifths of tube, 
and in legs (particularly at ends of tibiae and in tarsi, these 
being yellow) ; antennae dark brown, with base of segment 
I, apex and middle portion of II, and pedicel of III nearly or 
quite yellow, I V-VII darkest basally, III paler apically; 
wings of fore pair pale brownish and darker at base; 
ocellar pigmentation red. 
Head (PI. 1, fig. 3) fully 1.42 times as long as greatest 
width, which is at proximal third of cheeks, the latter nearly 
evenly but decidedly rounded to eyes and very slightly con- 
verging in basal third, with a somewhat wider and indis-
