Mr. Maskell for identification and was named by him Aleurodes 

 barodensis. 



Remedies.— A remedy that should be tried for attacks of this 

 past and one that is widely made use of in America against scale 

 insects is the kerosine emulsion already described. It has been 

 favourably reported on for destroying the green scale bug, one of 

 the most inveterate blights of the coffee tree, and also has been said 

 to have been successfully used in the Kangra Valley for destroying 

 scale insects on tea. 



Note. Aleurodes sp. — An unnamed species of Aleurodes has been reported as 

 attacking sugarcane. It may prove identical with the above, but all mention of it 

 should not be omitted here. 1 



In January, 1900, species of sugarcane leaf from South Arcot 

 were forwarded to the Indian Museum by G. Rajagopaul Naidoo, 

 Agricultural Inspector. He writes : — 



"The pest appears as numerous small ash-coloured oval spots underneath the 

 leaf blade. In some places only dark spots of similar dimensions are seen indi- 

 cating the marks left by the insects The development of green colouring matter 

 is arrested by the pest, causing the cane plant to look pale and stunted in growth. 

 No name is yet given to the pest, though the cultivator of the field says he is aware 

 of it for the last ten years. The soil of the field was loamy, in nature disposed 

 to be saline." 



Specimens forwarded to Mr. E. E. Green, Government Ento- 

 mologist, Ceylon, were identified by him as an Aleurodid.

Life history and description.— The following is Mr. Green's 

 description of the adult insect :— 



"Adult $ pinkish, the colour m)re or less concealed by a white powdery waxy 

 secretioii which is collected more particularly round the margins of the insect. 

 Form elongate ovate, more or less flattened from its position beneath the sheath- 

 ing leaves of its food plant. Legs and antennae comparatively small, but well 

 formed. Antenna? of six joints only, sixth always the longest, rather longer than 

 the second an i third together ; fourth always shortest; relative lengths of other 

 joints slightly variable. Foot with apparently only two digitules, fine pointed hairs 

 without knobs, 1 on claw and 1 on tarsus ; occasionally a second still finer hair on 

 tarsus; tarsus shorter than tibia, the two together shorter than combined femur 

 and trochanter. Anal ring with six stout hairs arising from a compact circum- 

 scribed patch of glandular cells. Anal lobes obscure ; scarcely — if at all prom-
