59. MESTOBREGMA KIOWA Thomas. 



(l'jlij)oda kiowaTnoMAfi, Ann. Ki'pt. IJ. S. (ieol. Surv. Terr., V, 1872, p. 461. 



Spot'iincns, both mature and immature, were taken on the .suunnit 

 of Pikes l*eak on snow fields, and a number of mature individuals of 1 

 both sexes were taken at the following places in Colorado and New ' 

 Mexico: Montevista August 13; Chama, New Mexico August 14; Fort 1 

 Collins August 9; Denver July 16; Golden June 19; Morrison June 23. 



But one specimen, a female, was taken at Montevista, and its wings ; 

 are pale citron })asallv. The same is true of four males from Chama, r 

 New Mexico, but all the others have the base of the wings hyaline, r 

 This appears to be quite constantly the case with specimens from 1 

 opposite sides of the divide. 



60. MESTOBREGMA PLATTEI Thomas. 



(Edipodu plattei Thomas, Kept. U. 8. Geol. 8urv. Terr., V, 1873, p. 123. 



Seven males, seventeen females, Denver Juh' 20; Chimney Gulch 

 July 27; Pine Grove July 23; Golden June 6 and August 21. 



The distinguishing feature of this species seems to be the pallid 

 coloring of the inferior posterior part of the lateral lobes of the thorax 

 and the ])ands of the tegmina extending only across the costal half. 

 The elj'tral markings resemble those of Tr'DiierotTopia pmudofasGiatv&A 



61. MESTOBREGMA PULCHELLA Bruner. 



Mestobrcgma puldieUnm Bruner, Proc. U. S. Nat. Mus., XII, 1890, p. 64-65. 



One male at Fort Collins August 9. This specimen agrees in every 

 particular with Bruner's type in the U. S. National Museum. This 

 species was omitted from Scudder's catalogue. It is a true McMo- 

 hregma.^ and is very closely allied to M. hkma in markings, and may 

 prove to be a synonym of that species. The color is its most distin- 

 guishing feature, and that may be due to environment. The food 

 plant from which it was described, Eurrotia lunata^ is recorded as occur- 

 ring from the "Northwest Territories to western Nebraska, Ne\\ 

 Mexico, Nevada, and California." 



62. METATOR PARDALINUM Saussure. 

 (Edipodd pdrdaliimm Saussure, Rev. Mag. ZooL, XIII, 1861, p. 324. 



Nineteen males, twelve females. Fort Collins August 11; Morrisoi 

 June 29; Golden June 19 and 30. 



Nine males and six females having "the base of the wings yellow, bul 

 in every other particular like the red-winged specimens, were taker 

 at the same localities and on the same dates. Very probably the^t 

 yellow-winged forms are the Mestohregina maculomm of Saussure.
