PKOCEEDINGS OF THE THIRD ENTOMOLOGICAL MliLlI.NG 37 



(Undetermined Eurytomine.) 



Another species of Eurytomine, as yet undetermined, has been found 

 to attack dhaincha pods at Pusa. We referred to this in our Annual 

 Eeport for 1917-18 and have figured the various stages [fgvres 

 exhibited]. Mr. Crhosh, will you tell us something about it ? 



The eggs are laid in the pods and the seeds are attacked. In each Mr. Ghosh, 

 seed attacked there is one grub which eats the cotyledons and then pupates 

 in the seed, the adult wasp gnawing its way out through the shell of the 

 seed and then through the wall of the pod. There is one grub in each 

 seed and each adult wasp gnaws a hole of exit for itself. The only satis- 

 factory method of control is the destruction of the affected pods. We 

 tried spraying the plants with crude oil emulsion to deter the adults 

 from ovipositing, but this did not keep them away. Picking out the 

 dried pods reduces the number of the wasps. 



Eurytoma indi. 

 This Eurytomine has been found at Coimbatore, the larva boring Mr. Fletcher, 

 and eating seeds inside agathi and dhaincha pods. It is apparently 

 distinct from our species in dhaincha at Pusa but works in a similar way. 



Megastigmiis indi. 

 This also occurs at Coimbatore in agathi and dhaincha pods. 



I have nothing new to add abo«t these two Eurytomines from Coim- Mr. Ramakrishna 

 batore. A^yar. 



Tenthredinid.?:. • 



Athalia proxima, Klug. 

 Athalia proxima is widely distributed in the Plains of India and is Mr. Fletcher, 

 usually a minor pest, sporadically bad, on cruciferous plants. We have 

 records from the following localities and food-plants : —
