to eradicate this pest once it is established, its appearance caused 

 great imeasiness to florists. Thepotato aphis [Macrosiphum solanifoln], 

 which is usually present in small numbers, caused great destruction in 

 some fields. Insect pests reported in the State for the first time 

 included the asparagus miner [Agromyza simplex'^.] and parsnip 

 web worm [Depressaria heracleana]. 



^A new pestj Pyrausta, nubilalis, Hbn. (European corn borer), was 

 found to have become established near Boston [see this Review. Ser. A, 

 vi, p. 554].

In view of the fact that the pink bollworm of cotton [Pectinophom 

 gossypiella] has apparently been eradicated in Texas owing to the 

 energy and co-operation of planters, a plan has been formulated for 

 permission to plant cotton in 1919 in the non-cotton zones in Texas, 

 other than the border zone, under the joint supervision of the State 

 and Federal Departments of Agriculture. Under this arrangement 

 the planter agrees not to plant any seed originating within a quarantined 

 or non-cotton zone, and to allow the Commissioner of Agriculture or 

 his agent to inspect or supervise the growing of his cotton in the fields, 

 to keep his cotton plants under constant inspection for any sign of 

 infestation, and to gather the cotton crop immediately it matures. If at 

 any time the presence of the pink bollworm is discovered, the 

 Commissioner of Agriculture is to have a free hand in dealing with 

 or destroying the crop. The planter furthermore agrees to use his 

 influence mth other planters to conform to this agreement and under- 

 takes to report any infestation of pinlc bollworm that comes to his 

 notice.

A rather severe outbreak of cutworms occurred in the Victoria 

 and Vancouver districts during May and the early part of June, 

 whole beds of garden produce being completely devastated. The 

 chief pests concerned were Feltia ducens, Wlk. (dingy cutworm), 

 Sidemia devastatrix, Brace (glassy cutworm), and the larvae of Euxoa 

 messoria, Grote, E. excellens, Grote, and Feltia vancouverensis, Grote. 

 The last-named species has not hitherto been regarded as of much 

 economic importance, but it appears to do as much damage as any of 

 the others, with the possible exception of S. devastatrix. 



During September a particularly bad infestation of shade and 

 ornamental trees occurred in Victoria, caused by the larvae of an 

 undetermined species of sawfly. In normal years its ravages are 

 confined to the Lombardy poplar {Populus dilatata), which is its 

 normal food-plant, but in 1917 it attacked everything in sight, even 

 invading houses and other buildings.
