Diptera form a very small and relatively -unimportant part . of 

 the crow's food, constituting less than half of 1 per cent. Tipulids 

 (crane-flies) are of the greatest economic interest, the adults, pupae 

 and larvae (leather-jackets) being eaten. Muscid and Sarcophagid 

 flies, their puparia and larvae were present in many stomachs examined, 

 occurring in considerable numbers in the case of some nestlings. 



The quantity of Hymenopterous insects taken by the crow is so 

 small that the economic considerations involved are practically 

 negligible, the same being true of miscellaneous insectSj mainly aquatic 

 forms eaten in marshy regions.

Very little damage was done to farm crops by insects during the 

 year under report. Leptocorisa varicornis (rice bug) is the cause of 

 very severe annual damage to the rice crops, particularly to the 

 early varieties. It is best kept in check by the method described in 

 the previous report [see this Review, Ser. A, vi, p. 186].

The outstanding entomological features of 1917 in Arizona were 

 damage by Aphis maidis, Fitch (corn aphis), the first record of notable 

 damage by Elasm,opalpus lignoselhis, Zell. (lesser corn stalk borer) 

 and severe injury to peaches in a few orchards by Anarsia lineatella, 

 Zell. (peach twig borer). This last-named moth is generally 

 distributed over the United States, also attacking, but less injuriously, 

 almond, apricot, plum and prune trees, and it is impossible to say 

 from its distribution, whether it has been present, unnoticed, for 

 several years, or has been introduced recently. The earliest injury 

 is caused by the pest boring into the buds and tender shoots, and the 

 same generation may destroy the young fruit in March, while adult 

 moths may appear as late as the first of November. The injured 

 fruit is subject to secondary attack by Carpophilus hemipterus (dry 

 fig beetle). A. lineatella may be successfully controlled by spraying 

 with lime-sulphur solution of the same strength as for San Jose scale 

 [Aspidiotus perniciosus], just before the blossoms appear. The 

 Cossid moth, Prionoxystus robiniae, Peck, (carpenter worm), a well 

 known pest of oak, poplar, cottonwood, willow, black locust tree and
