10a PllOCEEDIXGS OF THE THIRD ENTOMOLOGIC-VL MEETING 



Holotrichia repel ita, ShjJ. 

 This cockchafer beetle appears in large numbers at Ootacamund in 

 April. This insect damages cinchona to some extent. 

 It is found on cinchona in small numbers. 



{Unidentified Melolonthid).* 

 This cockchafer was sent in to us from Eanchi, the adult damaging 

 rose leaves, in swarms at night, 6 July 1916. (Mrs. Maxide.) 



( Unidentified Melolonthid) . 

 Sent in from Upper Shillong, 29 September 1904, the adult beetles 

 found on fruit-trees. 



(Unidentified Melolonthid). 

 The adults swarm at dusk in May in Shillong and eat Rnbvs leaves. 



{ Un identified Melolonthid). 



A second species found at Shillong in May 1918, the adult beetles 

 swarming at dusk and destroying leaves of Rubus spp. 



The habits of all these Melolonthids are almost similar. The beetles 

 all hide away in the day-time and come out at night just at dusk, and 

 feed upon leaves. Individual specimens probably do comparatively 

 little damage, but if many species appear together in large numbers 

 (as they usually do), considerable damage may be caused. The ordinary 

 remedy is to collect the adult beetles by hand or by light-traps. 



Is there any method of preventing the beetles from ovipositing in 

 cultivated areas l 



It is not possible to do so. In cultivated areas hoeing provides a 

 good remedy because it brings the grubs to light and is also good for 

 cidtivation. 



Light-traps are effective. The hfe-cycle of these beetles is one 

 year. 



Spraying with Bordeaux mixture may be tried. We found that, 

 in a garden where the grape-vines were attacked by a fungal disease 

 for which Bordeaux spray was given, a particular patch was left un- 

 sprayed by mistake and this plot was found to be very badly attacked 

 by cockchafers whilst the treated vines were quite untouched. 



In most districts spraying is impracticable because of the area to 

 be covered and because of the occurrence of rain. The cockchafers 



since been identified a« Schizoni/cha roficollii. F. We have it also from
