THE MONTHLY BULLETIN. 



Life History. — This is a truly migratory species, being very restless 

 and hardly remaining long enongh in one place to become harmful. 

 The first migration occurs in the Turloek and Newman districts* during 

 the early part of June. The swarms continue to move about through 

 September. The young reach maturity slowly and pairing begins in 

 August. The eggs are deposited in October and November and hatch 

 as soon as the ground becomes warm the following spring.

 Scudd. (Original.) 



Distribution. — Especially abundant in the central San Joaquin Val- 

 ley, in the region southeast of Turloek, but the range compris&s much 

 of the central part of the State. 



Food Plants. — Practically the same as for Melanoplus cliff ere ntialis, 

 though not so destructive to tfee crops. 



LOCUSTID^ (Family). 



THE LONG-HORNED GRASSHOPPERS. 



KATYDIDS. 



The members of this family are characterized by having long 

 filiform antennffi, four jointed tarsi and a six-pieced, fiat, sickle- 

 shaped ovipositor. The usual color is pale or bright green though 

 many members are quite dark. All are great singers. The wings Avhen 

 present are large but thin and delicate. Practically all of the species 

 are vegetable feeders and while more or less destructive are not so 

 much so as the short-horned grasshoppers {AcrklUdcc) . 



The control of the members of this family is practically the same as 

 for the short-horned grasshoppers.
