Indian species and none are likely to be found in the cultivated areas. 
Westwood figures a number of Indian species (Cab. Or. Entom., 1847). 
Brunner listed 19 from Burma, and Bolivar 26 from South India. Kir¬ 
by’s Catalogue enumerates 65 Indian species. 
Pulchriphyllium (Phyllium) scythe Or. (figs. 17, 18) is a large leaf¬ 
like insect, whose life history is described by Murray and quoted in Sharp’s 
Insects. It occurs in forest areas in Assam. 
AcRimiDiE.— Short-horned Grasshoppers. 
The antennce short; the auditory organ on the first abdominal segment; 
the ovipositor composed of short valves formed for digging ; tarsi 
three-jointed. Hind legs long , and saltatorial. 
Fig. 19— Acridium m el a nocorn e. 
A family which can scarcely ever be confused in the field; the short 
antennse and leaping hind legs mark a true grasshopper at once. The 
size varies from a length of a quarter and a wing span of nearly half an 
inch to a length of over two inches and a wing span of three to four. 
The majority are less than one inch long, the smallest among the Tetri- 
ginee, the largest among the Acridiinoe. Size is usually sufficiently 
constant to be valuable as an indication of species. With few exceptions 
the colour is cryptic ; the colour schemes harmonize so closely with the 
natural surroundings that the insects are difficult to see. Since the life 
is a long one and the surroundings vary with the change of season, it is 
common to find that, while the nymph is also cryptically coloured, the 
colour may not be the same as that of the imago. There may be two or 
more actual colour schemes in the whole life, both cryptic and adapted
