isolated areas over which it is common. These localities are more frequent 

 in mountainous and hilly regions than in open country. Atlanu is the species 

 that often occurs in hurtful numbers throughout the New England States. 

 and also at various other localities throughout the interior. In general 

 appearance and habits, atlanis approaches sprehis more closely than it does 

 femur-rub-rum or any of our other North American M<'l>i<>[>li. of which 

 there are upward of fifty described species. 



78. Melanoplus spretus Thos. McPherson Co. (Rundstrom). 



There is but a single specimen of the much dreaded Rocky Mountain 

 Locust contained in the collection before me, which would indicate an un- 

 usual freedom from its presence throughout the State at this time. At 

 any rate, this is true in reference to the localities from which the various 

 portions of the collection came. As there has so full a history of this 

 locust been written at various times in the past, and it is familiar to every 

 one, I will not say anything further of it here. Should anyone wish to 

 read what lias already been said on the subject, I would refer him to the 

 three reports of the U. S. Entomological Commission relating to this and 

 several other injurious insects that have attracted general attention on ac- 

 count of their great destructiveness. 



79. *i<'i;iEBO|in* devastator Scudd. (iarden City (Cragin). 



There is contained in the material from the above-named locality a single 

 pupa of a locust that I refer to this species, although the insect in ques- 

 tion has not heretofore been recorded from that immediate locality, but has 

 been taken at Morrison, Col. This is the locust which does much injury 

 to crops in California and adjoining portions of Oregon. It also occurs 

 throughout Montana and in northern Dakota, and I have taken it in Idaho 

 and northwestern Wyoming. 



80. Melanoplus luridus Bodge. Reno Co. (L. A. and H. P. O'Hara); 

 Barber Co. (Cragin). 



This species belongs to one of the groups in which the cerci of the males 

 are forked, M. collinas, M. tenebrosus, M. nigre>ccns and M. delator being 

 the other species of the present group. It was firsr described from Dodge 

 Co., Nebraska, but occurs on uplands throughout all of eastern Kansas and 

 Nebraska, as well as in Iowa and Missouri, with perhaps a more extended 

 range. 



81. IVIelanoplus angustipennis Dodge. Barber Co. and Topeka (Cragin). 

 This species belongs near M. cinereu* Scudd., a species found throughout 



the Sage-brush regions of the West and Northwest, where it (J/. cinereut) 

 feeds upon and lives among the foliage of the different species of Arti'inisi<i. 

 M. angustipennis, likewise, has the habit of hanging about plants of a sim- 

 ilar nature and, like that species, this is more "arboreal " than otherwise, 

 preferring to jump from plant to plant rather than to alight upon the ground. 

 I have the species from as far south as Dimmit Co., Texas, and from Kt. 

 Buford, Dakota. It also occurs at Anaheim, California. 



82. Melanoplus flavidus Scudd. Barber Co. (Cragin). 



These are the first specimens of the species that I have seen. It was 

 described from specimens taken at Morrison, Col., and is evidently re- 

 stricted in its distribution to the plains of Colorado and Kansas.
