Family Ecacanthothripide, Bagn. 
Hood suggests that this family should be sunk as a 
synonym of Phleothripide, despite the bizarre nature of the 
antennal sensoria—a character which must be regarded as 
of some importance when we remember that the type of 
sense-cones remains constant and the same throughout the 
other members of the Tubulifera (Phlceothripoidea) through- 
out the families Phlceothripide, Idolothripide (+ Mega- 
thripide), and Hystrichothripid. Only in Ecacanthothrips 
(+ Ormothrips) do we find a striking departure in this direc- 
tion. I may add that the type of antennal sensoria in the 
main families of the Terebrantia is peculiar and constant 
to each family (vide Molothripide, Heterothripide, and 
Thripidz). 
Genus Ecacantuorturirs, Bagn. 
4. Ecacanthothrips sp. 
There is a single ¢ example referable to the sanguwineus 
group. It possesses the pilose fore-femora seen in Ceylon 
examples (H. steinskyi), but the intermediate antennal joints 
5 and 6 would appear to be basally yellowish as in san- 
guineus, and not unicolorous as in séeinskyi. The hind- 
femora have a series of six stout, erect, infundibuliform 
' setee along their upper margin, and the fore-wings a series 
of twenty-eight duplicated cilia (sixteen to twenty in san- 
guineus, teste Karny). The pronotal sete of the fore-angles 
are very long. I have kept this specimen for future study. 
According to Schmutz steinskyi has a series of fifteen to 
twenty duplicated sete in the fore-wing, but of a series of 
material from Ceylon apparently representing two species 
both with the antennz unicolorous (one of which is almost 
certainly steinskyi) all possess twenty or more duplicated 
sete. 
It is quite clear that all existing material of this group 
requires closer study in the light of recent advances. It 
would seem that EZ. dryanti, Bagn., is at once separated by
