18 THE CANADIAN ENTOMOLOGIST. 



Melanoplus Packardii Scudd. There are quite a number of this species 

 in the collection, taken at Umatilla, Oreg., and also near Ellensburg. 

 These specimens are interesting since they all have the hind tibiae red 

 instead of bluish, as in the typical specimens from Nebraska and neigh- 

 boring States. 



Melanoplus extremus Walker (?). The collection also contains a few 

 specimens of a Melanoplus which is referred with some doubt to this 

 species of Walker's. The insect in question is somewhat closely related 

 to M. atlanis Riley, but differs from this species in its larger size, more 

 robust form, comparatively shorter tegmina and wings, the much longer 

 and more upturned last ventral segment of the male abdomen, and m the 

 longer and broader cerci of the male. The general color is a dirty yellow- 

 ish with markings of dull brown and black, arranged much as in M _ 

 atlanis. The female can be distinguished from that of atlanis in its more 

 robust form and the much heavier and more rounded prosternal spine. 

 Hind tibias dull yellow, with a very faint brownish tinge in some specimens. 



There are also specimens of this insect in the collection of the U. S. 

 National Museum from Ft. McLeod, British America, and Helena, Ft. 

 Ellis and the Madison Valley, Montana, and also Salmon City, Idaho. 



Melanoplus fe?noratus Burm. A few specimens from W. T. 



Melanoplus sp. The collection also contains a few specimens 



of what appears to be still another species somewhat closely related to 

 M. atlanis and M. scriptus Walk , but which were not critically examined 

 when the specimens were before me. These were also taken in W. T. 



There are also quite a large number of specimens of the genus Tettix 

 which I have not tried to determine, of which there are at least two species. 

 I expect, however, to work up this section of the Acrididse after I have 

 more material at my command than at present. 



GRVLLIDiE. 



Gryllus luctuosus Serv. ? The specimens in the collection which are 

 referred to this species with some hesitation, are all females, and have the 

 ovipositor very long, i6 m.m. Taken at Spokane, W. T., and Umatilla, 

 Oreg. 



Gryllus jiei:;lectus Scudd. There are five fentiales of another species 

 which are referred here. They have the ovipositor lo m.m. in length. 

 Portland, Oreg.
