EIGHTEENTH ANNUAL EEPOET OF STATE ENTOMOLOGIST 13 



and "'the child of the desert," attracted much attention. Inquiries 

 were received from numerous localities throughout the central and 

 eastern parts of the state concerning- the identity of this compara- 

 tively rare orthopteron. 



Large Lubber Grasshopper (Braclvystola magna Gir.). The 

 largest representative in Montana of the grasshoppers, the females 

 of which measure from two to three inches in length, was more com- 

 mon than for many years past. The State Entomologist's office 

 received almost ten times the usual number of inquiries concerning 

 this insect. 



Warrior Grasshopper (Camnicla pelluaida Scudd.). This species 

 was again prevalent in the state and during May and June hatched 

 out in enormous numbers from egg beds in Beaverhead, Missoula, 

 Flathead and other western counties. Had not control measures 

 been forcibly carried out great financial loss due to this insect 

 would have been sustained. 



Lesser Migratory Locust {Melanoplus atlanis Ril.). 



Two-Striped Grasshopper (Melanoplus bivittatus Say). 



Whereas the warrior grasshopper was the principal species, and 

 in many cases the only one concerned in western Montana, the lesser 

 migratory and two-striped forms preponderated in outbreaks of 

 grasshoppers in eastern Montana. 



THE TRUE BUGS, PLANT LICE, ETC. (HEMIPTERA) 



Chinch Bug (Blissus leiicoptcrus Say.) For the first time since 

 1911 the chinch bug made its appearance again in the vicinity of 

 Glasgow. Nymphs were collected by County Agent Stebbins on 

 May 27th and sent in to the laboratory. 



Currant Aphis (Mysus ribis Linn.). This yellowish-green plant- 

 louse, which causes the curling up of currant and gooseberry foliage 

 by extracting the plant juices from the leaves, was more abundant 

 in Montana than for many years past. Many inquiries concerning 

 control measures reached the Department of Entomology too late 

 for any good to result, as spraying must be done before the leaves 

 are badly curled. 



Sunflower Aphis (Aphis cornifoliae Fitch). This dark-colored 

 aphis which feeds. on the under sides of the leaves of cultivated sun-' 

 flowers grown for ensilage has increased along with the remarkable
