rROCEEDIXGS OF THE THIPD ENTOMOLOGICAL MEETING 321 



Before leaA-ing beetles, I may add a few remarks ou the following 

 insects which have already been noted as injurious, just to point out 

 their present status in view of our further knowledge of these insects. 



Pempheres affinis. This insect has within the past tW'O or three years 

 distributed itself with Cambodia cotton into tracts where it was not 

 found till now — viz., Madura, Ramnad and Tinnevelly districts. It 

 appears that the weevil exists in different parts where no cotton is grown 

 — for I noted the weevil on Hibiscus esculentus in North Malabar — and 

 makes itself prominent with the introduction of cotton cultivation. 

 The Hfe-history of the insect has been worked out and an account of it 

 will be found in my paper on this insect in the Year Book of the Madras 

 Department of Agri^cvlfure for 1918 (pp. 1—13) [Coloured plate exhibited]. 



Alcides bubo. (Plate 13). This insect continues to be a bad pest 

 of Sesbania (agathi) in betel- vine gardens. The plants do not suffer 

 much when they have grown 4 or 5 feet high ; but during the younger 

 stages very serious damage is done. Two or three apjDlications of lead 

 arsenate during the earlier stages at intervals of a fortnight checked the 

 attack in the early stages. I am exhibiting a coloured plate showing 

 the different stages of this pest. Two parasites Metastenomyia juliani, 

 Gir., and Eurytoma pigra, Gir., have been noted on the grub ; but not 

 to any great extent. In page 97 of the Madras Departmental Year-Book 

 for 1917 is a short paper of mine on the egg-laying habits of this insect. 



Alcides affaber. This is a specific pest of gogu {Hibiscus camnabinvs) 

 and is also found on Hibiscvs esculentus ; pretty bad occasionally. Alcides 

 leopardus, 01., mentioned by Fletcher in his book, is api^arently a wrong 

 identification for A. affaber, for I have never seen A. leopardus anywhere 

 in Coimbatore. I, however, got some specimens of this latter species 

 breeding on a wild plant in South Malabar a couple of years ago. 



Peltotrachelus pubes — a weevil noted in the Shevaroys on orange 

 This is a minor pest only. 



Apoderus tranqiiebaricus. Recently this insect has been noted in 

 numbers on tender shoots and leaves of mango trees in Chittur and adja- 

 cent mango tracts. (Reference to my note in Bulletin of Second Hundred 

 Notes). 



Pachytychius mungcnis, originally noted on green-gram, is also found 

 on dhaincha as a pretty bad pest, causing prominent swelhngs of the 

 stem. 



Olenecamptus bilobus (Plate 10, figure /<), though noted by Lefroy in 

 his Indian Insect Life, is not in Fletcher's book. It is sufficiently 

 important to be grouped as a pest. I have noted this doing damage to 

 cultivated figs in Krishna, Bangalore, and other places. It was once 

 noted on pomegranate also in Salem, Coimbatore.
