2. Circotettix carlinianus. 



Oedipoda carliniaiia Thom., Proc. 

 acad. nat. sc. Philad., 1870, 81 (1870). 



Oedipoda carlingiana Thorn., Ann. rep. 

 U. S. geol. surv. ten., II, 265, 275 

 (1871); Thom., Syn. Acrid. N. A., 126 



(1873). 



Circotettix larlingiantis Thom., Proc. 

 Dav. acad. nat. sc, I, 254-255 (1876); 

 Sauss., Prodr. Oedip., 176 (1884). 



Circotettix carliniauus Sciidd., Proc. 

 Dav. acad. nat. sc, VIII, 42 (1900). 



Named, according to Thomas, after 

 Col. Carlin. The g has entered the 

 name apparently as a typographical 

 error. 



This species varies greatly in tlie 

 coloring of the wings as regards the 

 extension from the base of the fuscous 

 infumation ; it may cover more than 

 half the wing, or it may he entirely ab- 

 sent except from the veins, but in the 

 latter case there is often a faint indica- 

 tion of the upper portion of a median 

 cross-band, as in some other species ; 

 this is especially the case with speci- 

 mens from British Columbia, but is also 

 seen in one from southern Colorado. 

 British Columbia specimens are also 

 smaller than those from further south. 



In my notes on the songs of our 

 Orthoptera given in the 23d Report of 

 the Entomological society of Ontario, 

 p. 78, 1 have made for this species state- 

 ments which belong instead to C. iindiil- 

 a/iis. The present species is by no 

 means so noisy, remaining only five or 

 six seconds in the air during its flights, 



and making a rustling sound rather than 

 a crackle, — ■ in fact more closely resem- 

 bling the faint rustle of C. maculatus. 

 I have before me specimens from the 

 following localities, all, unless otherwise 

 specified, taken by myself: — Colorado, 

 7-8000' (Morrison); Garland, Col., 

 8000', Aug. 28-29; Pueblo, Col., July 

 8-9; South Park, Col., 8-10000', Aug. 

 11-16; Douglas Creek, Col., Aug. 22; 

 White River, Col., July 24-Aug. 13; 

 Green River, Wyo., July 21— 31; Alkali 

 Station, Wyo., 6000', July 27 ; Fossil, 

 Wyo., Sept. 2 ; Parowan, Utah, 6000', 

 July 3-10 (Palmer); Reno, Nev., Aug. 

 18 (Packard); British Columbia and 

 Vancouver Is. (Crotch). Other regions 

 from which it has been reported are : 

 from Ft. Benton, Mont., to Ft. McLeod, 

 Alberta (Bruner), Montana (Thomas, 

 Bruner), the Yellowstone region (Bruner, 

 Saussure), Yakima Wash., and north- 

 western Nebraska (Bruner). 



3. Circotettix thalassinus. 



Circotettix thalassinus Sauss., Prodr. 

 Oedip., 177-178 (1884). 



I have received this species only from 

 Nevada (H. Edwards), from which state 

 it was described by Saussure, and from 

 Tahoe Co., Cal., August (Mus. Leland 

 Stanford Univ.). 



4. Circotettix lobatus. 



Circotettix lobatus Sauss., Add. prodr. 

 Oedip., 65-66, pi, fig. 5 (1888). 



Circotettix lapidicola Brun.!, Proc. U. S. 

 nat. mus., XII, 75-76 (1890).
