Cercyothrips. New Genus. Family Thripidae. 
Antennae 8-segmented, maxillary palpi apparently only 2-segmented, 
sense cones on segments 3 and 4 forked, mouth cone broad and heavy reach- 
ing nearly across prosternum. Head produced between antennae which 
are inserted far apart close to the eyes, and are directed somewhat laterally. 
Cheeks strongly converging posteriorly. Prothorax shorter than the head 
and without the usual spines at the angles. Anterior and intermediate 
tibiae unarmed; legs stout. Wings well-developed, with two veins sparsely 
set with spines, 9th segment of abdomen the longest. Spine on abdominal 
segments 9 and 10 stout. 
This genus suggests Limothrips somewhat in the projection of the 
head between the eyes. The antennae are very similar to those of some 
species of Sericothrips, notably variabilis.
