towards the tips of the wings, silvery gray beneath. The only markings are along the 

 front costa and at the apex of the fore- wings. The costal marks consist of 10 or 12 

 short, black streaks separated by similar clear white dashes ; near the apex is a flask- 

 shaped mark which bears 4 or 5 short, longitudinal, black dashes. Last year the attacks 

 of the Pea Moth upon pease in Ontario were considerable, Mr. John McMillan, M.P 

 for Huron, even putting the loss at one-third of the crop in his district. 



Remedy. — As a remedy, deep ploughing has been recommended. It has also been 

 found that early sowing and the cultivation of early varieties enable the pease to mature 

 before the moths are on the wing. The perfect insects have been reared both in 1897 

 and last season. In the former year all the specimens emerged between July 12 and 15, 

 and in 1898 between July 13 and 15. These specimens were kept under natural condi- 

 tions, and these dates probably agree with the time the moths appear naturally in the field. 

 The Bean Weevil (Bruchus obtectus, Say, Fig. 45). From time to time notices 

 appear in reports of entomologists and in the newspapers in the United States of inj ary 

 to seed beans by a weevil similar to the Pea "Weevil, but rather smaller. This is the 

 Bean Weevil, a small, very active beetle, at one time thought to be a native of America 

 but now considered to be a cosmopolitan species, which has been imported into this 



country through commerce. Authentic instances of this 

 pest having occurred in Canada in injurious numbers have 

 not, I believe, been recorded until this year, when it was 

 found at Strathroy, Middlesex Co. As in the case of the Pea 

 Weevil, the Bean Weevil occurs in the seed and is sown 

 with it. The eggs are laid on young forming pods and 

 the grubs eat their way inside and attack the seeds. There 

 is, however, one important difference in the life history, 

 namely, the bean weevils are able to propagate in the dry, 

 stored seed, and two or three broods may come to maturity 

 and entirely ^destroy the beans, whereas in the case of the Pea Weevil the young grub can 

 only begin life in the soft, green pease ; again, there is never more than one weevil in a 

 pea, while in the case of the Bean Weevil, ten, twelve, or more, may occur in a single 

 bean, according to its size. 



Remedy. — The remedy for this new enemy of the bean is precisely the same as for the 

 Pea Weevil, viz., to fumigate the infested seed with bisulphide of carbon. If, however, 

 it is found that the beans have been badly bored before the injury is detected, it is far 

 better to destroy the whole by burning and procure new seed without going to the trouble 

 and expense of fumigating. 



Fodder Crops and Roots. 



Fodder crops of most kinds have been remarkably heavy in most parts of the Pro- 

 vince during the past season. In the Ottawa Valley such crops of clover 

 bave never before been seen, and with the exception of a little injury by 

 the Black Army-worm, Noctua fennica, Tausch. in the spring, both crops 

 were exceptionally heavy and were saved in the best of condition. In 

 the west one or two occurrences of the Clover weevil (Phytonomus puncta- 

 ius, Fab.) were mentioned but no appreciable effect upon the crop was 



The Clover-seed Midge (Cecidomyia leguminicola, (Lintner) did a 

 good deal of harm in the seed growing districts and some farmers speak of 

 turning their attention to the Mammoth Red Clover and Alsike, because 

 these varieties are not injured by this troublesome insect. The remedy 

 of feeding off or mowing the crop before the 20th June has been found 

 satisfactory by those who have tried it, because the maggots (Fig. 46) of 

 the first brood mature and leave the clover heads to enter the ground and 

 complete their changes soon after the date given, and if the clover is fed or 

 cured before that date the larvae are destroyed If left later the maggots 

 leave the clover heads and produce the second brood which matures just
