marmoratus and psecilocera hieroglyphica defoliate sugar- 

 cane. The most destructive of all the grasshoppers is the 

 Hieroglyphus furcifer which attacks paddy and maize plants. 

 (4) Then come the Gryllidze, or the crickets \Ui-chingri, 

 usrang, jhingun), the abdomens of which are furnished with 

 long ovipositors. An enormous mole-cricket (Schizodactylus 

 monstruosus) is injurious to young tobacco and other crops 

 growing on high land in Behar, where it is known as Bherwa. 

 Gryllotalpa sp. is a cricket which is said to injure opium 

 plants by cutting them off when they are considerably ad- 

 vanced in growth. Acheta sp. is said to injure young opium.

and other rabi crops. (5) The long horned grasshoppers 

 (locutidae, which, however, do not include the common locusts 

 and grasshoppers) are somewhat rare. 



i, 216. Neuroptera. All the four wings are of similar 

 texture and with numerous veins. The wings are sometimes 

 hairy. The Dragon flies (jhinji pokd y or jhinji-p'haring) are 

 the commonest example of this order. They can be seen 

 in Lower Bengal in the month of October specially in large 

 numbers chasing their insect prey wherever they fly and 

 they are to be looked upon as one of the best friends the 

 farmer has. Their larvae live in water, and the larvae of the 

 few species that do live on plants feed on aphides &c. The 

 white-ant is the other commonest example of this order, but 

 they are exactly of the opposite character to draggon- 

 flies and for the study of this a separate Chapter will be 

 provided.
