42 REPORT ON INJURIOUS INSECTS FOR 1905. 



The fly makes its way out of the pupal case towards the end 

 of May or early in June; the first to emerge in 1904 appeared on 

 May i/th, and in 1903 on June 3rd. 



PREVENTIVE AND REMEDIAL MEASURES. 



Towards the end of May, and again early in June, holly bushes 

 or trees should be sprayed with paraffin emulsion or dusted with 

 equal parts of soot and lime; both are equally disagreeable to the 

 female fly. Very few leaves were attacked where one of these 

 materials had been used. 



THE RIBES GALL-MIDGE. 



Various correspondents have forwarded branches of Ribes 

 alpinum covered with galls formed, I think, by a Cecid or Gall- 

 Midge. 



FIG. XXIII. --GALLS ON Ribes alpinum. 



In some of the specimens the larvae were found, and an 

 attempt to breed out the midges was made, but proved unsuccessful.
