is about 15 percent conplete in the counties of central Now Mexico. 
The hatch of M. mexicanus was estimated at 5 percent comolete by May 
16, 
Texas. (April 21-26)* A few newly hatched nymphs were reported in Hart- 
ley, Hutchinson, Hansford, Ochiltree, and Lipscomb Counties. Popula- 
tions along margins of wheatfields in Lipscomb County ranges as high 
as 10 per square yard with 1 per squire yard in most fields. The 
majority of nymphs observed were Aulocaro olliotti SFhos, and A. 
turnbullii , with a few M. mexicanusT (May" 4-10 ) : Pirst-instar nymphs 
of A. turnbullii and M, mexicanus wore observed in the northern part 
of the Panhandle, the former being the dominant species. Populations 
were low except, in Hansford, Ochiltree, and Sherman Counties, where 
concentrations along fence rows adjacent to wheat numbered up to 15 
■per square yard. (May 11-17)* Populations are composed of 50 per- 
cent A. turnbullii and 30 percent M. mexicanus , and nymphal con- 
centrations along wheatfield margins number 20 per square yard. ■ 
Oklahoma. (May 4-10 ): Scattered rains and continued cool weather through- 
out the Oklahoma Panhandle arc causing a prolonged hatch. Populations 
ranged as high as 20 per square yard, in part of Harper County and up 
to 6 per square yard in Beaver end Texas Counties. (May 11-17)* A 
rapid increase occurred in the hatching of grasshoppers throughout 
the northwestern Oklahoma, Panhandle. The hatch is now approximately 
25 percent complete, A. turnbullii , the dominant species, is mainly 
in the second instar, with a few in the third. Most M. mexicanus are 
in the first instar. Populations as high as 50 per square yard, main- 
ly A. turnbullii , were observed along margins of alfalfa fields in 
Harper County; the numbers present in Leaver, Cimarron, and Texas 
Counties are considerably lower. 
Kansas. (April 27-May 3)* Cool and rainy weather during the week retarded 
development of eggs. Considerable hatching, however, took place in 
the southwestern part of the State. In the more sandy areas as many 
as 15 to 20 nymphs per square yard were, observed in idle fields and 
as high as 50 or more nymphs per square yard in margins. The hatch 
is estimated to be 5 percent., complete, and 75 percent of the A. turn- 
bullil are estimated to have hatched. A very small percentage of M. 
mexicanus have hatched, inasmuch a„s the pods of this species are gen- 
erally buried more deeply; less than 10 percent of the nymphs observed 
were M, mexicanus . Practically all nymphs are in the first instar and 
are active and feeding on young Russ ian-this tie. (May 4-10): Weather 
conditions during the last week have been favorable for grasshopper 
development. Crop conditions are excellent and marginal vegetation is 
luxuriant, affording ample food end cover for grasshopper populations. 
In the southwestern part of the State A. turnbullii was 75 percont 
hatched and M. mexicanus 30 percent hatched, with' both species being 
75 percent first-instar, 20 percent second- instar and the remaining 
few, third-instar nymphs,. M. mexicanus is the dominant species, 
followed closely by A. turnbullii . Populations range from 5 to 50 per 
square yard in the fields and from 10 to 150 per square yard on margins 
w ith abandoned land and depleted range being the chief sources of in-
