3. STENOBOTHRUS CURTIPENXIS, Harr. 



Syn. Locusta curtipennis, Harr., Cat. Ins. Mass. 56. 

 Chloealtis curtipennis, Harr., Rep. 3d ed. 184. 

 Stenobothrus longipennis, Scudd., Boat. Jour. Nat. Hist. 1862, vol. vii, 457. 



At various points. 



4. STENOBOTHRUS MACULIPEXNIS, (No. 86. ) 



(EDIPODINI. 



5. TRAGOCEPHALA VIRIDIFASCIATA, Harr. 



In the Rio Conejos Valley numbers were observed. 



6. TRAGOCEPHALA PACIFICA ?, Thos. 



Tragocephala pacified, Thos., Syn. Acrid. N. Am. 161. 



From camps along the Rio Conejos and Rio Chama, July, 1877. Elevations 7,000 to 

 9, 000 feet; abundant. 9 probably viridifaaciata, but possibly jpaci^ca, as the disk of 

 the pronotum is distinctly granulated; the median carina in the foveola of the vertex 

 is distinct, extending into the sulcus of the frontal costa. No. 10, 98-109 inclusive. 



7. TOMONOTUS SULPHUREUS, . 



Colors very strong (the dark portion of the wings apparently larger in proportion 

 to the yellow than usual?). 63-65; 64 9 . 



8. TOMONOTUS TENEBROSUS, Scudd., <. 



Syn. (Edipoda tenebrosa, Scudd., Hayden's Geol. Surv. Neb. 251 



Tomonotus pseudo-neietanuj, Thos., Proc. Acad Nat. Sci. Phila. 1870, 80. 



Tomonotus tenebrosw, Thos., Syn. Acrid. N. Am. 107. 



Arphia sanguinaria?, Stal, Kecen. Orth. 119. 



Arphia tenebrosa, Scudd., Bui. TJ. S. Geol. Surv. 1876. 



Arphia simplex?, Scudd., Proc. Bost. Soc. Nat Hist, xvii, 1874, 5. 



Arphia conspersa?, Scudd., Proc. Bost. Soc. Nat. Hist, xvii, 1874, 5. 



Arphia luteola?, Scudd., Proc. Bost. Soc. Nat. Hist, xvii, 1874, 5. 



There is really but little difference between this species and T. sulplnirea except the 

 color of the" wings, and T. carinata of Scudder appears to form a connecting link. 66. 

 (95-60 & 77-57 9.) (81 <?.) 



9. ARPHIA NEGLECTA. 



Syn. (Edipoda neglecta, Thos., Proc. Acad. Nat. Sci. Phila. 1870, 276. 



Arphia neglecta, Scudd., Bui. U. S. Geol. Surv. 1871, 46. (No. 12.) 



10. ClRCOTETTIX UNDULATA. 



Syn. (Edipoda undulata, Thos., Geol. Surv. Terr. 1871, 46. (Nos. 62 &73.) 



11. MESTOBREGMA PLATTEI, 1? , 



Syn. (Edipoda plattei, Thos., Syn. Acrid. 123 



The specimens being in c"olor show the wings to be a bright yellow at the base ; the 

 dash-band is very distinct black, and occupying about | of the length of the wings. 



12. MESTOBREGMA KIOWA, Thos.,-<?. 



Syn. (Edipoda Kioiva, Thos., Geol. Surv. Terr. 1871, 461. 



Psinidia Kiowa, Thos., U. S. Geog. Surv. West 100th Merid. vol. iv, 885. 



Two or three specimens. These specimens enable me to make the following addition 

 to the description as given in my ' ' Synopsis of North American Acrididae. " The median 

 carina of the pronotum may properly be described as somewhat prominent, the wings 

 pale lemon-yellow at the immediate "base, the remaining portion of the wings being 

 transparent with dark nerves and nervules. It would probably have been better to 

 have made the specific nameplatteana, (No. 72. ) Do. 9 Usually a broad flesh-colored 

 band extends obliquely across the face from the middle of the clypeus upward and 

 backward across the cheek toward the occiput. A black stripe runs obliquely down- 

 ward and forward from the lower and hinder margin of each eye to the middle of the 

 lower part of the face, where those from the opposite sides meet. The vertex above this 

 is a dull flesh-color. 88-58. Do. 9, (84-57), (93-59). 



13. SPHARANGEMON COLLARE, Scudd. 



Syn. (Edipoda collaris, Scndd. Hayden's Geol. Surv. Neb. 250.
