other natural enemies in controlling it. The Arctiid, Es(igmen6 

 acraea, and Alabama argillacea Avere observed in some localities; the 

 former species also attacked PJii/salis angulata var. linkiana. The 

 cotton boll-worm {Chloridea obsoleta) did no serious damage ; about 

 38 per cent, of the eggs were parasitised by Trichogramma pretiosum. 

 Melanoplus dijferentialis was found on cotton near Phoenix. Buccu- 

 latrix thurberiella, a new pest of cultivated cotton, was found in the Salt 

 River Valley. This leaf-mining caterpillar has previously been recorded 

 on Arizona wild cotton {Thwheria thespesiodes). When nearly full- 

 grown, the larvae eat their way to the surface of the leaf, continue 

 feeding there for a short time, then undergo pupation on the leaf. 

 The Rutelid, Cotalpa co7isobrina, was found on cottonwood trees and 

 was abundant in South Arizona in July.

During the years 1913-14, all nurseries known to the State 

 Entomologist were inspected twice yearly. In the inspection of 

 foreign importations, 106 shipments of nursery stock were examined. 

 Egg-masses of Orgyia {Notolojjhus) antiqua (vapourer moth) have 

 been found several times on roses from Holland. Pupae of a 

 Noctuid moth were found on cherry from France. Among scale- 

 insects. Coccus hesperidum (soft brown scale) occurred on bay trees 

 from Belgium, Diaspis boisduvalU on palms from Belgium and 

 Lepidosaphes idmi on box from Holland. Gracilaria zachrysa (azaleae) 

 and Aleurodes sp. on azaleas from Belgium and Holland respectively ; 

 Aphids on maple from Germany, and on hydrangea and roses from 

 Holland ; red spider (Tetranychus) and mites from Belgium and 

 Holland. Regular notification has been made of plants imported 

 from the gipsy and bro^ai-tail moth quarantine area in New England. 

 Shipments of bulbs showed some infestation by Rhizoglyphus hyacinthi 

 (bulb mite) ; in several cases fumigation was ordered. A few trees 

 affected with what is apparently the San Jos6 scale {Aspidiotus 

 perniciosus) have recently been noticed.

The method of preparation of each of the following fungicides is 

 given : Copper sulphate, Hme, Bordeaux mixture, and hme-sulphur 

 concentrate. The method of determining the concentration by means 

 of the hydrometer is described, together with a dilution table for 

 concentrates testing from 15° to 35° Baume. Ammoniacal copper 

 carbonate and soap are frequently used upon nearly mature fruit ; 

 the formula for making 50 U.S. gals, is as follows : Copper carbonate, 

 6 oz. ; strong ammonia, 3 pts. ; soap, 1 lb. ; water, 50 gals. The 

 ammonia is diluted with two or three times its volume of water, the 

 carbonate is dissolved in it and the solution made up to within 5 gals.
