Cylas formicarius, F. (sweet potato weevil) has been studied and 

 ajjparently does not fly long distances. Evscepes porcellus, Boh., 

 which also attacks sweet potatoes in Jamaica, has been found on 

 Calonyction aculeaium and Ipoinoea pescaprae in southern Florida. 



Other injurious insects occurring in great abundance include the 

 fall webworm [Hyphantria cunea] in Florida, and the pecan-nut case- 

 bearer {Acrobasis hebescella) in Texas, both on pecans ; the blackhead 

 fireworm \I(hoj)ohota txicciniana] on cranberry in Washington ; the 

 larger stalk borer {Papaipema nebris) on tomato in Mississippi ; the 

 asparagus beetle {Crioceris asparagi, L.) in Maryland and Virginia ; 

 mealy bugs {Pseudococcus) and Pulvinaria sp. on figs in Louisiana, 

 the Argentine ant [Iridomyrmex hmnilis] being a potent factor in the 

 distribution of mealy-bugs ; and grain pests {Silvanus surinamensis 

 and Calandra oryzae) in ware]iouses in Oregon.

During 1917 the vineyards in Castile were infested more severely 

 than usual by the vine flea-beetle, Haltica ampelophaga. This article 

 contiains notes on the life-history of this pest and describes various 

 remedies, of which spraying with an arsenical solution is held to be 

 the best. An economical formula — anhydrous sodium arsenate 2 lb., 

 lime in paste 3 lb., water 50 gals. — is given with full directions for 

 preparing it.

Prompt measures are needed in Alicante against Haltica ampelo- 

 phaga. In Cordova evergreen oaks have suffered from the persistent 

 attacks of Lymantria {Lijyaris) dispar and Tortrific viridana. The 

 former moth has begun to do the same damage in Salamanca and 

 Seville.

The Swiss Department of National Economy issued in June 1918 

 an order prescribing the measures to be apjjlied against the white 

 cabbage butterfly [Pieris] with a view to preventing the loss, amounting 

 to several millions of francs, sustained in 1917. The collection and 

 destruction of the eggs and young caterpillars are especially aimed 

 at, catching the adults being a less efficacious method, though one 

 also provided for. The various Cantons are responsible for the 

 carrying out of the work.
