No. 5,] Miscellaneous Notes. 58 



In September 1893, specimens were forwarded from Baroda, by Mr. 



T. IJ. Middleton, of a scale insect which attacks 



Sugurcane scale in- , i • i in n/r ,: 



sect. siigarcaDG leaves, and is knowD locally as mam. 



The insect proved new to the Indian Museuna 



collection, so was sent to New Zealand for examination by Mr. W. M, 



Maskell, who has since kindly examined it and reports that it represents 



the pupae o£ a species of Aleuiodes not yet precisely identified. 



In January 1893, a number of blighted orange leaves \\ ere forwarded 



to the Museum by the Revd. Mr. Carleton, ot 

 Orange blight. „ , ^. '. ,,y, , /» i ^ 



Kotgarh, near bimla. Ihe leaves were louud to 



be covered with vast numbers of little scale-like insects, Mr. Carleton 

 re(.oited that the blight had appeared upon one tree about two years 

 previously, and the following year had spread to all the orange trees in 

 the orchard. Its effect was to stop both growth and fruiting*. The 

 insect proved to be new to the Indian Museum collection, but as it was 

 obviously allied to the coccidse, attention was directed to the system of 

 kerosine spraying and gas treatment, described in previous numbers of 

 these Notes, which have been employed with much success against this 

 class of insects in the United States. 



In the mean time the specimens were submitted to Mr. W. M. 

 Maskell, the specialist on coccidse, for further examination, Mr. Maskell 

 has since been so kind as to examine the specimens, and reports that 

 they are the larvae and pupse of a species of Aleicrodes. The material was 

 insufficient for precise identification^ b^t the species is likely to be allied 

 to Aleurodes quercus^ Signoret, though the dorsal punctuation is scattered 

 instead of being in radiating lines as in this form. Mr. Maskell notices 

 that the adults are likely to be small four-winged flies, probably yellow- 

 ish in colour, with wings covered with white powder or slightly spotted. 

 The remedies he recommends are similar to those used against coceid;ie. 



In September 1892, leaves covered with the remains of white cottony 



.„ ^ , looking bh'ght were forwarded by Mr. C F. Elliott, 



A Quetta rose blight. , , ^ i • r% / 



who wrote that rose oushes in Uuetta were much 



affected in this way. The insect has been kindly examined by Mr, 



W. M. Maskell, who identifies it as an Aleurodid possibly allied to the 



European form Aleurodes protella, Linn. The material, however, which 



consists chiefly of empty pupal cases covered with white cottony secretion 



is insufficient for precise identification.
