74 Indian Museum H^otes, [Vol, HI. 



la July 1892 some damage from Aerididse was reported in the 



■ .,., . _. „. Tinnevelli district. In a report received 



Acndidse in Tmnevelli. i.i-n ipt. t,*i n 



througn the Uoard or Hevenue^ Madras, the 



Collector of Tinnevelli writes :— 



" I have the honor to forward a bottle received from the Tahsildar of Serivilli- 



putur containing specimens of a species of grasshopper. He reports that these 



insects have appeared in certain villages of his taluk, where in several places they 



have been found to injure the young ragi crops. The damage is as yet but slight." 



Specimens were afterwards received through the Government Cen- 

 tral Museum, Madras. They were found to comprise the following 

 species, as determined in the Indian Museum collection : — 



(a) Acridium cBruginosum, Burm., thirteen specimens. 



(o) Crotogonus trachypterus^ Blanch., three specimens, 



(c) (Edalus marmoratiis, Linn., two specimens. 



(d) Catantops indicus, Sauss., two specimens, 



According to a subsequent report by the Collector, furnished by the 

 Board of Revenue, Madras, the insects made their first appearance about 

 the 20th May, and a week later were found in twelve villages. They 

 disappeared before the end of July. Writing on the 2nd July the 

 Collector observes: — ''They occur as ova, wingless larvse and fully 

 developed insects. The damage to the crops is said to be as yet but 

 slight, but cannot, the tahsildar reports, be estimated before the 

 harvest/' 



The specimens furnished through the Madras Museum in connection 

 with this report comprised the following species as determined in tlie 

 Indian Museum collection : — 



(a) (Edaliia marmoratus, Linn., eighteen adults. 



\b) Oxya velox, Burm., fifteen adults. 



(c) Pacluitylus cinerascens, Fab., one adult. 



[(T) Crotogonus trachjpterus, Blanch., one adult. 



(e) Tryxalis turrita, Linn., twenty-seven specimens including 



both adults and larvse. 

 Under these circumstances it would appear that the damage was 

 due rather to multiplication of numerous local forms than to special 

 incursion by migratory locusts. 



Injury from Acrididse was reported in the Madura District in 



, .,., . ,, , August 1892. The following is an extract
