REPORT OF THE ENTOMOLOGIST AND BOTANIST. 173 



Ashes appear to drive them away for a time. They eat the plants right to the 

 ground." — S. A. Bedford, Brandon, Man. 



" July 6, — Cantharis Nuttalli made its appearance on my beans on June 19, but 

 we have had no such immense numbersof them as last year yet." — Thomas Copland, 

 Saskatoon, Sask. 



" July 7. — I inclose you a few insects that are doing considerable injury in the 

 North-west this year. They attack the Siberian pea tree {Caragand), beans, tares 

 and peas, and in other places garden vegetables. I have used Paris green with good 

 effect. Last year a few were found in our tares ; so far this is the only pest that has 

 troubled us much this year. It seems to especially appreciate Prof. Eobertson's 

 horse-beans." — Angus Mackay, Indian Head, Assa. 



The insects sent were Cantharis Nuttalli and the Black Blister-beetle (Epicauta 

 Pennsylvanica. DeG.). It was probably the latter which was referred to as attack- 

 ing garden vegetables. 



"July 4. — I send you to-day some insects, and shall be very much obliged for 

 any information yon can give me about them ; they have appeared on my horse- 

 beans which I have planted with corn. They eat the leaves only, beginning on the 

 outer edge and leaving the stalks and veins of the leaves. They have appeared on 

 a spot three or four rods square. I do not think they breed on the plants. If these 

 are likely to prove destructive, please tell me what I must do to destroy them. They 

 do not eat the corn which is planted in the same hill as the beans." — Percy G. 

 Mills, Sussex, N.B. 



The insects sent by Mr. Mills were the Gray Blister-beetle {M. unicolor, Kirby). 



The remedy recommended for blister-beetles on beans in my report last year is 

 as follows : " In looking over all the reports received I find that they are all dated 

 in July, so that the time of injury to this crop will seem to be limited to a few weeks, 

 and if a sharp watch were kept for their appearance, the ravages could be controlled, 

 either by sweeping the crops with a net mounted on a handle or by beating the 

 beetles into a pan containing some water with a little coal-oil on the top. When the 

 area attacked is too large for this, spraying promptly with Paris Green, 1 lb. to 

 100 gallons of water (or dusting with 1 lb. of Paris green to 50 of flour) would 

 destroy them." 



V^EGET_A.BLES. 



Garden vegetables in Eastern Ontario this season have not suffered very severely 

 from insect enemies, although the abtindance of some has made up for the non-ap- 

 pearance of others. The root maggots of the cabbage and onion were very destruc- 

 tive. In the case of the cabbage, experiments with Kerosene emulsion and Hellebore 

 tea poured round the roots of infested plants were to a large measure successful. 

 The Onion Maggot was also experimented with by sowing common salt along the 

 rows and in the bottom of the drills : the results were conflicting, but on the whole 

 quite encouraging, and it is proposed to continue the experiments next year. 



Cabbages this year in Eastern Ontario had an almost entire exemption from the 

 attacks of the Imported Cabbage Butterfly (Fieris rapce, L.). 



Beans were damaged in many places during June by Cut-worms of several 

 kinds, Carneades ochrogaster. Gn., being the most genei-ally distributed species. This 

 caterpillar has a very wide range of destruction, specimens having been received 

 from Cape Breton to Calgarj-, Alta. The protection of freshly set out herbaceous 

 plants by wrapping a small piece of paper aiound the stems has been highly com- 

 mended by several to whom this remedy had been suggested. Celery was received 

 which was heavily infested late in the season by an Aphis. It was too late, the crop 

 having been dug, to apply the usual remedies for plant lice. 



Tomatoes were injured in some places by plant bugs and a report was received 

 from Mr. W. G. Baylay of Ottawa, of the girdling of the main stem by the Buffalo 

 Tree-hopper (Ceresa bubalus, Fab). The insects were, however, fewer than when 

 he recorded the same damage in a previous year. The Tomato Stalk-borer {Hydroecia 

 cataphracta, Grt.) was somewhat prevalent in the Ottawa district, the larvte being
