FIG. 250. 



Olenecamptus bilobiis, Fabr. 

 United Provinces. 



The grubs of this beetle are to be found plentifully in Dehra Dun and 

 southwards throughout the plains of the United Pro- 

 Life History, vinces and Bengal in the three fig - trees mentioned. 

 They appear to affect old decaying trees, and I have 



not found them myself in young, green, healthy trees. The beetle appears 

 on the wing in the hot weather and at the commencement of the rains. 

 Lefroy (Indian Insect Pests, p. 376) mentions the beetle as common on 

 pakar, gular, and other rigs in the plains.
