58 THE FLORIDA ENTOMOLOGIST 
NEW THYSANOPTERA FROM FLORIDA—XIII 
J. R. WATSON 
92. Podothrips semiflavus Hood. 
Mr. George B. Merrill on October 1, 1924 collected a number 
of thrips of this species from a swamp grass collected at Davie 
by Bowers and Link of the State Plant Board. It has been re- 
ported from Cuba and Porto Rico on sugar cane. The writer 
has received it from the Virgin Islands when it was collected 
on Para grass by Mr. C. E. Wilson. The present find extends 
its known range to Florida and adds a new host.

Head, considerably wider than long, broadest across the posterior mar- 
gin of the eyes, cheeks well arched, short, about a third the length of the 
eyes, front produced into a triangle in front of the eyes, the two front 
sides of this triangle (across the bases of the antennae) almost straight 
but slightly produced between bases of antennae, tip with minute notch; 
surface with several rather prominent longitudinal striations and a sin- 
gle pair of bristles near the anterior angles of the eyes. 
Eyes rather large, dark, pilose. Ocelli situated more anteriorly than

eyes, bordered by wide dark red crescents. Mouth cone reaching rather 
more than half way across prosternum. 
Antennae 2.5 times as long as head. Segment 1 rounded, about three- 
fourths as long as wide; 2 inverted foot-shaped, but the ‘‘toe” very short,
