P. S. — As no one except myself, so far as I know, is giving much attention 

 to our ''Micros,' and as I have a good many new, beautiful and interesting 

 species, if you desire it I shall occasionally notice them in the Ento- 



MOI OGIST.

HINTS TO FRUIT GROWERS. 



Paper No. 2. By Wm. Saunders, London, Ont. 



The gooseberry saw fly Ncmatus Vcntricosus. The season of warmth 

 and growth having opened this year early, this never-failing pest has put in 



its appearance also in advance 

 of previous years : as early as the 

 23rd of April I found the insect 

 on the wing preparing to deposit 

 its eggs as soon as the foliage 

 was sufficiently expanded. Our 

 last number contained an en- 

 larged figure of the fly — See fig.

 position, feeding on the leaves. 

 (See fig. 12.) The fly deposits 

 itswhite eggs in long regular rows 

 on the under side of the leaves, 

 chiefly on the larger veins, where 

 they speedily hatch, and the hundreds of voracious worms resulting are soon 

 scattered all over the bushes. Already, May 15, the eggs are very nume- 

 rous, and here and there may be found a colony of larvae. These latter, 

 while young, feed in company, from 20 to 40 on a leaf, which is soon 

 riddled with the small holes they at first make, but in a few days they 

 increase in size, and parting company spread in all directions. By keep- 

 ing a close watch, and picking off the eaten leaves early in the season, 

 the evil will be much lessened, but where the worms are numerous 

 there is nothing so good as Powdered Hellebore, which may be readily 

 and economically applied by mixing an ounce (previously rubbed up
