and great heat both seem unfavourable to it. Attempts to rear other 

 parasites, such as the Evaniid, Prisiaulaciis ni gripes, Kieff., the 

 Bethyhd, ScJerodermns donicsficns, Latr., and other Hymenopterous 

 parasites have been disappointing, and it seems almost impossible 

 to breed sufficient numbers to be of any economic value, though it is 

 too early yet to pronounce definitely on this point.

This paper deals with the moulting, movement, feeding habits 

 and reproduction of Macrosiphnin tanaccti, L. 



This Aphid is apparently confined to a single food-plant, Tanacetum 

 vulgare, on which it may be found from early spring until late in 

 autumn feeding on the more succulent portions of the plant, especially 

 on the growing parts of the stem.

Enuring the autumn of 1921 the corn ear worm [Hcliotliis ohsolcta, F.] 

 became very abundant in Ontario, and was in several instances mistaken 

 for the European corn borer [Pyrausta nubilalis, Hh.]. A brief account 

 is given of the introduction and the seasonal history of the latter. 

 In Ontario the food-plants include all kinds of maize, of which the 

 sweet varieties appear to suffer most. The amount of infestation 

 also depends on the time of planting, the injur}' being greater on early 

 maize.

Cultural practices for the control of Ern'opean corn borer [Pyrausta 

 nubilalis, Hb.] in Ontario are described.

The occurrence and life-history of Pyrausta nubilalis, Hb., in Canada, 

 as well as remedial measures and the precautions to be adopted in 

 1922, are briefly stated.

Jasmin plantations in Callian (Var), where the plant is largely cul- 

 tivated for the perfume industry, have been found to be infested 

 with the Pyralid, Glyphodes itnionalis, Hb. The moth is nocturnal 

 in its habits, and evidently oviposits in the interior of the flowers, 

 which open at night. The larva, after feeding inside for some time,
