of oranges or lemons and by increasing the amount of bran to 25 lb., 

 the bait was made attractive to young hoppers, A modified Griddle 

 mixture consisting of 50 lb. fresh horse manure, 1 lb. Paris green, 

 1 lb. salt, and three oranges is recommended for use against the young 

 forms. The bait should be scattered on damp ground if possible. 

 Stictoce])hala festina (three-cornered alfalfa hopper) was destructive 

 to a lucerne seed crop near Phoenix. Injury is due to the feeding 

 habits of both immature and adult forms, which suck the juices from 

 the stems. The scars produced sometimes appear as rings or girdles 

 with a gall formation, and the stem is liable to break off at this point. 

 Clean cultivation is the only suitable control measure. The Erotylid 

 beetle, Languria mozardi (alfalfa stem borer) was present in injurious 

 numbers in the Salt River Valley in the summer of 1915. Coarse stems 

 were more subject to infestation than the finer ones, and damage was 

 greatest in fields which had not been well cultivated and irrigated. 

 Sugar-cane was attacked by Diatraea sp., probably lineolata (Mexican 

 moth borer), and by Sphenophorus phoeniciensis (bill bug). The last- 

 named species was present in June and the beginning of July, attacking 

 mainly the young canes. The point of injury was usually at, or near 

 the junction of the new cane with the mother stalk. Pupation was 

 observed to take place in the soil and probably began after 8th July, 

 Damage was most serious in a plot which for several years previously 

 had been left to grow Bermuda and Johnson grass. Maize was 

 attacked to a marked degree by the cotton boll worm [Chloridea 

 obsoleta], especially during August. In one field from 70 to 75 per cent, 

 of the stalks were infested, but the yield was not appreciably reduced. 

 The larvae over a small part of the field were destroyed by shaking a 

 mixture of equal parts of lead arsenate and flowers of sulphur into the 

 unfolding buds. This method of control should not be used in cases 

 in which the stalks are required for fodder. Owing to the unusual 

 winter conditions in 1914-15, the melon aphis [Aphis gossypii] was 

 abundant on the weed, Malva parviflora, and later became prevalent 

 throughout melon fields. Natural enemies were abundant and acted 

 as effective checks. This fact suggests that it is more important to 

 guard against Aphids in melon fields during seasons which are not 

 favourable for continuous winter breeding than during those in which 

 the insect is found in large numbers upon weeds before melons are 

 planted. Three unidentified species of bhster beetles were reported 

 as attacking vegetable crops. Cutworms were abundant in southern 

 Arizona. Trichobaris trinotaia (potato-stalk weevil) increased in 

 importance in the southern parts of the State, The native food-plant 

 is the yellow-flowered ground cherry. The eggs are laid in punctures 

 in the stalks of the host plant, and the larval and pupal stages are 

 passed in the middle of the stem. There is probably more than one 

 generation annually. The only practical measure of control is the 

 destruction of weeds in which the insect may breed. The salt marsh 

 caterpillar [Estigmene acraea] appeared as a pest of beans in one locality. 

 The egg-masses can be collected by hand or a lead arsenate spray used 

 against the larvae. The most destructive cotton pest was a Capsid 

 bug allied to Lygus pratensis. Clean cultivation and autumn and 

 winter ploughing are important in reducing the numbers of the insect. 

 The cotton leaf caterpillar [Anomis argillacea] was generally distributed, 

 but in smaller numbers than in preceding years. Tetranychus bimaculatus
