JJo- 5.] Scale Insects in Madras. SI 



As it is of the greatest iroportanee that this pest should not spread 

 to cultivated crops, I would recommend the destroyinof of all the infested 

 plants by burning. Frona what I can gather the food-plant at present 

 known is but a weed, so there need be no compunction about the matter. 

 December would be the best month for destroying the pestj as they will 

 not til en have laid their eggs. 



Below is a list of other species sent :— 



Lecanium hemisphericum — On leaves and stems of a climbing 

 rose, in the Milgiri Hills. 



Lecanium sp. ? — Scales of the $, and perfect $ ; food-plant 

 not identified. In absence of the ? 1 do not think it wise 

 to describe the species, which is probably new. 



? Chionaspis — On rose leaves. Scales of the $ only. Nungum- 

 baukum, Madras. 



Aleyrodes sp. — On a low creeping plant, very like our British 

 ''Bindweed" (Convolvulus). Insects in all stages. The 

 white wings of the imagines are spotted with black. 



Aleyrodes sp. — On same plant as Aspidiotus orientale, and same 

 locality. The pupa is rather large and black ; dorsum and 

 margin with very long white waxy fringe; that on the 

 dorsum erect, and matted together, forming a large mass, 

 but does not completely cover it.
