THYSANOPTERA. 
1. Female with an ovipositor. Wings with two internal and one 
marginal vein. (Terebrantia). 
1. Antennae nine-jointed. Ovipositor curved upwards. Molothri- 
pidce. 
2. Antennae six to eight-jointed. Ovipositor curved downwards. 
Thripidce . 
II. Female without ovipositor. Wings veinless or with one short 
internal vein. Antennae eight-jointed. Body flattened, apex 
of abdomen tubular. (Tuhulifera) Phlceothripidce. 
The recorded Indian species are members of the last family ; Idolo- 
thrips halidayi, Newm. and (?) Phlceothrips anacardii, Newm., were 
described from specimens found on Anacardium in Mysore, while (?) 
Phlceothrips stenomelas, Newm., was found in Ceylon. The species 
described as Physopus rubrocinctus, Giard., also occurs in Ceylon and 
belongs to the Thripidce, as do the tea thrips. 
Very little is known of thrips in India, though they occur 
commonly. We have two species which are destructive to pulse crops, 
but they have been found only once. Another is known to attack 
opium, a fourth is recorded as attacking turmeric in Madras. (Indian 
Mus. Notes, I, p. 109.) 
At least one species is common in flowers, the flowers of Sann Hemp 
(Crotalaria juncea), being commonly full of a harmless thrips. Others 
have recently been destructive to tea in Darjeeling and other larger 
forms have been found. There is probably a considerable number of 
species which require collecting and observing. Specimens should be 
preserved in spirit, as they are useless dry, unless exceptionally large.
