" It would be hazardous to describe the colours o£ the living insects from samples 

 preserved in spirit, but it ma}"^ be fairly assumed that the colours are of a grey-brown 

 or black, with a few obscure spots on the sides and dorsum. When placed iu spirit, 

 they yield to it a deep port wine red tint, and the same stain tinges the insect& 

 mounted in Canada balsam." 



Iu September 1890 were received, from the Agricultural Department, 



. ^, Rang-oou, pui')Ee of a moth belono-ing to the 



Paddy caterpillars m Bhamo. = '^ ^ ,., .. , rr 



tamily Limacodidm, said to have proved de- 

 structive to paddy in part of the Bhamo district. The specimens were 

 insufficient for precise identification. 



From the Sub-Manager of the Encumbered Estates, Ranehi, were 



. „ ,. received in Seiitember 1890 a number of hair- 

 Rice caterpillars m Rancni. \ 



covered caterpillars probably belonging to the 



heteroeerous family Lasiocampidce, but in too poor condition tor precise 



identification. They were said to attack Dhan and Mama crops in Loliar- 



dugga, the damage annually done by the insect in one pergunnah being 



estimated at from four to six annas of the total crop. The caterpillars 



appear in the rainy season and defoliate the plants, trenches being dug 



by the cultivators to prevent their passing from the upland crops to 



attack the rice which lies at a lower level. 



The Executive Commissariat Officer at Thayetmyo reports that the

Ants attacking potatoes. _ . . . 



seed in the Commissariat garden in 1889-90 

 was considerably reduced b}^ the ravages of a small ant which attacked 

 the tubers wlien quite young. No specimens have been furnished, but, 

 according to Dr. Walsh, the insect may perhaps have been the common 

 red ant Solenopsis gemminata. The only remedy suggested is that of 

 following the ants to their nest and destroying them there with boiling 

 water, kerosene oil, or bisulphide of carbon. 



In October 1890 the Collector of South Areot reported injury to
