204. AcRiDitJM PEREGRiNUM Oliv. (the locust of North- West 

 ■ India). — Periodieallj' invades the fertile plains of India from its home in 



the sandy plains of Rajputaua, Sind, and the Punjab. It is also pre- 

 valent throughout the whole of South-Eastern Asia and Northern Africa, 

 The full-grown insect is a big thick-set grasshopper, with short anteuiiEe. 

 When it first acquires its wings it is salmon pink in colour, but as it 

 gets older it becomes at first yellowish and afterwards dull purple in 

 tint. It forms vast flights, which are sometimes thick enough to hide 

 the sun from sight as they pMss in the air. The young are little black 

 and yellow wingless grasshoppers which emerge from the eggs that are 

 laid in the ground. The insect feeds voraciously throughout the whole 

 of its eyistence, and both in its wingless and winged stages does much 

 damage to green standing crops of all kinds over wide areas in India. It 

 also attacks the foliage of trees, and in fact almost every kind of green 

 plant. 



205. AcRiDiUM STJCCINCTUM Linn. — There is evidence to show that 

 this is the insect which did most of the damage to standing crops in the 

 Deccan and Konkan in the Bombay locust invasion of 1883-83. It is 

 the locust which was reported in the Fatna district in 1877, and which 

 has since been reported as destructive to crops in Murshidabad. It is 

 superficially much like Acridiuin peregrinum, but belongs to the damper 

 and more fertile regions of India.
