as early as May 1st, while adults were numerous and freely 

 pairing by July 20th. In early August it had become scarce, 

 but about the middle of September many adults were again 

 found, pairing freely, and the species was still common in October 



These interesting notes by the energetic discoverer of this' 

 new species indicate that, in the Chilcotin, it is probably double 

 brooded. 



We are told that individuals are much sought after by the 

 Indians for fish bait. 



Specimens Examined: 245; 137 males and 108 females.

Melanoplus chiricahuae new species (Plate III, figs. 9 and 10.) 



This handsome insect agrees closely in size, coloration and 

 general appearance with M. t femur-nigrum Scudder, a species 

 known from the northern portion of the Arizona Plateau. 



In male cereal development nearest approach is found in 

 M. calidus Scudder, which species occurs in the White and Sac- 

 ramento Mountains of south-central New Mexico. The cerci 

 of that species are, however, much broader and shorter, with 

 broadened apical portion more conspicuously truncate. In 

 other features wide differentiation between these two species 

 occurs, chiricahuae being clearly much more closely related to 

 femur-nigrum. 



Type. — <? ; Ida's Peak, Chiricahua Mountains, Cochise County, 

 Arizona. Elevation, 8000 feet. June 28, 1919. (Witmer Stone.) 

 [Acad. Nat. Sci. Phila., Type no. 5381.] 



Size and form medium for the group. Vertex and frontal costa as in femur- 

 nigrum. Eye large, nearly twice as long as infra-ocular sulcus. Pronotum 

 as in femur-nigrum: medio-longitudinal carina weak on prozona, very weak 

 between transverse sulci, moderately decided on remaining portion of meta- 

 zona, sulci distinct but not deep; lateral margins of pronotal disk subparallel 

 to principal sulcus, caudal margin of same broadly obtuse-angulate produced 

 with apex rounded. Prosternal spine longer than broad, slightly transverse, 

 cylindrical to distal portion which tapers off strongly to the rounded apex. 

 Tegmina very slightly longer than pronotum. almost attingent, oval, with 

 apex rounded, though not broadly so. 



14 The bulk of this series is in the Canadian National and Philadelphia 

 Collections. Sets, however, will be sent to the other larger North American 

 collections of Orthoptera.
