Glenbrook, on the east shore o£ Lake Tahoe, he found atlanis abund- 

 ant in hay fields and wheat stubbles. 



August twenty-third he entered Shasta Valley by way of Berryvale 

 (Sisson's). Found feviur-rubrum in abundance and atlanis less com- 

 mon, both in damp meadows, while the species of (Edipoda were in 

 the hot exposed fields and by the roadsides. Found no dead locusts 

 under the stones upon Shasta cone, as commonly found on the peaks 

 of the Eocky Mountains. ♦ 



At Portland, Oregon, August thirtieth, he found femur-rubrum, and 

 the same next day at the Cascades of the Columbia; also, perhaps, the 

 beautiful species noted as being found in Sierra Valley so like atlanis 

 but with short, useless wings and blue shanks. 



At Umatilla, Washington Territory, September second, he found 

 atlanis in abundance on the sage and grease bushes; also, the blue- 

 legged locust. 



in Yosemite Valley and southern California he found only species 

 of (jedipoda and no authoritative notes indicating that the migratory 

 locusts inhabit the region, but they may, nevertheless. 



Harry Edwards, the distinguished entomologist, whom Californians 

 have lately allowed to remove East with his choice collection of thou- 

 sands of carefully preserved insects, collected the different species 

 described in these papers within the limits of California, all except 

 the spretus. This fearful, long-winged, immensely abundant locust 

 cannot — thanks to the mysterious limiting instincts which govern it- 

 reach, much less cross, the Sierra barrier. 



The writer within the two last seasons has detected atrox at the fol- 

 lowing places: Plains of Colorado, San Gorgonio Pass, plains of S^n 

 Bernardino, gardens of Los Angeles, Mohave Desert, fields of Santa 

 Barbara, San Luis Obispo, Cholame Valley, Tulare Valley, San Joa- 

 quin Valley, wheat fields of Merced, Yosemite Valley,' Big Tree Grove, 

 Livermore Valley, San Ramon Valley, Santa Cruz, Santa Clara Val- 

 ley, side of Mount Hamilton, Alameda fields, side of Mount Diablo, 

 side of Tamalpais, Roseville Junction, Marysville, Chico, United States 

 Fishery, McCloud River, Berryvale, near Shasta, Shasta Valley, Pit 

 River, Goose Lake, West Valley, Surprise Valley, Plumboldt Desert, 

 Pyramid Lake, Eagle Lake, Honey Lake, Big Meadows, Indian Val- 

 ley, American Valley, Mohawk Valley, Sierra Valley, Truckee Mead- 

 ows, Tahoe Lake, and Mono Valley. He has seen femur-rubrum and 

 atlanis at Santa Cruz, Yosemite, Tahoe, San Rafael, Berryvale, Pit 

 River, Surprise Valley, Big Meadows, Sierra Valley, Truckee Mead- 

 ows, and Carson Valley; but spretus he has never seen alive within 

 our State. 



THE OUTLOOK. 



And this is the comfort we may gather from all this investigation, 

 that our present California scourge, noticed in many places of late 

 years, and notably in Sierra Valley and vicinity, is not the hateful 

 spretus ot the Rocky Mountains, liable in any fair day of midsummer 

 to drop out of the sky in overwhelming myriads, but only a low- 

 flying, local, and usually harmless species, which, for some reason, 

 has been of late unchecked. But the great number of parasites noted 

 on them of late, the presence of the big, fat, egg-eater in such abund- 

 ance, and of the other enemies noted, almost demonstrate that nature
