represented by a single green species with the broad head of Ledra, 
but which is easily distinguished by the absence of the ocelli from the 
head above. Thomsoniella is represented by two small dull green 
species, so far known only from Bengal, but probably far more widely 
spread. Selenocephalus virescens, Dist., is known from Bengal and 
Assam, a dull green species with a groove across the apex of the head. 
Krisna strigicollis, Spin., is a larger dry-grass coloured insect, more 
than half an inch long in large specimens, widely spread in tropical 
and sub-tropical India. Goniagnathus punctifer, Wlk., is a broader 
brown insect, widely spread over the plains, as in the hills ; Varta 
rubrofasciata, Dist., is a larger green insect, the tegmina with red 
lines found as yet only at Pusa. 
Nephotettix includes the green species which are so well known to 
"Calcutta residents as the “ fly ” which comes in hordes to light 
towards the close of the rains. Two species are concerned, N. 
bipunctatus, Fabr., in which the female is green, the male green with 
two black spots and N. apicalis, Motsch., which is green, much 
marked with black. They come freely to light and in the humid heat of 
Lower Bengal multiply immensely and are a distinct plague. Deltoce- 
phalus and Paralimnus are recorded from the plains. 
Typhlocybince .—“ The Typhlocybince are readily separated from all 
the other sub-families of the Jassidse by the four longitudinal veins or 
sectors of the tegmina which run to the transverse veins defining the api¬ 
cal cells without branching, so that there are no ante-apical cells and also 
by the absence of supernumerary cells in the wings. ”—(Gillett in 
Distant.) 
Empoasca flavescens , Fabr., is the well-known “ Green fly ” of tea, 
recorded by Distant from India, Ceylon, East Africa, Brazil, Europe, 
Britain, United States and the whole Palearctic Region. It is one of 
the insects which by sucking the apical shoot check the growth of tea and 
lessen the yield, though improving the flavour. Ordinary contact 
poisons check it readily. The very delicate green nymphs are common 
on tea, but it is not easy to be sure how much damage is really due 
solely to this pest. Empoasca notata, Mel., is a common insect on castor. 
The eggs are laid in the soft tissues of the leaf mid-rib and the bright 
grreen nymphs suck the leaves, causing curling and distortion. The 
imago is green, with only dull white markings on the vertex and
