Through the kindness of Dr. N. Annandale I am able to describe 
the following interesting species of Thrips which was submitted to 
me with other Indian material in r9g09. The specimens were col- 
lected more than thirty years ago, and on that account are not in 
such good condition as one would wish. I have however made a 
greatly enlarged drawing which shows the chief features of both 
sexes, and whilst the following description is a very complete one, 
considering the fragmentary state of the material, I hope later 
to have the pleasure of examining some newly collected specimens 
and thus be enabled to more accurately describe and figure cer- 
tain parts. 
Apart from its economic importance the species is one of 
considerable interest. It belongs to the sub-order Terebrantia and 
in certain features, such as the general character of the head and 
prothorax and the form of the antenne, it would appear to be 
closely related to the genus Heliothrips, but a number of strong 
and peculiar characters (italicized in the generic description) are 
of such importance, I consider, as to render it advisable to place 
the genus into, at least, a sub-family of its own, the Panchaeto- 
thripinae. 
Dr. Annandale has sent me the following transcription of the 
reference to the specimens, which appeared in the “Indian | 
Museum Notes,’’ Vol. 1, t&889-1891—Entomology Notes—by E. C. 
Cotes, p. 109 :— 
“‘ Specimens were received on 21st May, 1889, from the Board 
of Revenue, Madras, through the Superintendent, Government 
Central Museum, Madras. Swutta thegulu, small black-winged insect, 
frequently jumps from one place to another. This attacks the 
plant when two months old. The leaves become rolled up, green- 
ish in colour, turning pale yellow, and the leaves gradually be- 
come dry. This spoils the turmeric crop, and rhizomes are not 
developed. Eggs are also deposited on the back of the leaves. 
Sutta thegulu is considered to be a severe form of attack.”
