Durmg 1920 the following insects have been reported of economic 

 interest: The Hessian fly was sent in to the Vernon Laboratory __by the 

 Superintendent of the Sidney Experimental F'arm. This is a new record 

 for the l^rovince. although, judging from the present known area of 

 infestation, it has been present for many years. Our information until 

 1918 was to the effect that while this insect was widely distributed west 

 of the Cascades in both Washington and Oregon States, it was not known 

 to occur north of Seattle. It is probable that this insect will cause very 

 considerable trouble to fall wheat on the Island and measures for its 

 control will have to be figured out. The satin-moth was reported by 

 Dr. J. McDonough. of Ottawa, who determined this insect for Mr. A. B. 

 Eaird, who collected it. This moth is now only known to occur in British 

 Columbia in the City of New Westminster, and the only other point at 

 present infested in the North American Continent is Massachusetts. 

 Hence it is believed to be an imported pest of recent standing, as it is 

 common, I believe, both in Europe and Siberia. It is impossible at this 

 time to state how important this insect may become during the next few 

 years, but there is no c|uestion but that it will require careful watching. 

 The Colorado potato-beetle, reported last year by Mr. W. H. Lyne for 

 Gateway, in the Lower Kootenay country, was this year noted by 

 Mr. W. B. Anderson at Waldo, a spread of 40 miles in a year. The 

 currant elm-aphis, reported by Mr. Downes from Chilliwack and 

 identified by Mr. \\'. A. Ross, of the Dominion Entomological Branch, 

 \'ineland, Ontario, as Eriosoma ulmi, is noted for the first time. Anis- 

 andrus pyri (the shot-hole borer of the West) was, I believe, introduced 

 to our nolice by Mr. J. W. Eastham, who obtained identification through 

 Dr. J. M. Swaine in Ottawa. This insect was taken in the neighbourhoo.d 

 of South \''ancouver. Mineola tricolorella was again reported from 

 A'ernon, while the studies of Mr. Venal)Ies have brought to light the 

 following list from the apple: Bruce's measuring-worm, Rachela 

 bruceata, Epicallima dimidiella, Peronea maximana, together with the 

 established identity of other common fruit-infesting larvje, such as the 

 lesser apple-worm, bud-moth, and the dock false worm. Several other 

 insects attacking fruit have been found, but their identity is not yet 

 disclosed. Peronea maximana may be further mentioned for the reason 

 that it is closely related to Alceris (Teras) minuta, an insect which is 

 noted by Mr. J. R. Anderson in his Bulletin No. 12 of Provincial Depart- 

 ment of Agriculftire, and as long as I can remember this insect has been 

 mentioned to me as being present in British Columbia, but no specimens 

 had been received. It is just possible that T. minuta may have been 

 confused with P. maximana, but of this we have no definite information. 

 Of those insects Mr. Buckell has found infesting the range lands of the 

 Province I cannot make mention at this time. Suffice it to say that he 

 has enriched our locust knowledge by establishing the presence of about
