others; apical angle slightly obtuse, but not blunt; disk somewhat rugose. 

 Elytra and wings rather narrow, passing the abdomen. 



Color (dried after long immersion in alcohol) dull clay yellow, with 

 fuscous dots and spots; occiput with two indistinct fuscous stripes; disk 

 of the posterior lobe of the pronotum dusky brown in the center, margins 

 yellow; there are, also, generally two dusky spots on each side of the 

 pronotum, near the front margin. The elytra have three fuscous bands 

 across them, the one nearest the apex generally more or less obliterated 

 by the transparency of this part; the apex pellucid; wings pellucid; 

 nerves of the anterior portion dusky, the rest ocherous. Posterior femora 

 with three indistinct brownish bands exteriorly, the inside black next the 

 base, and a smaller spot of the same color near the apex, rest yellow; 

 tibiae dull yellow (probably blue when living), slightly dusky at the base 

 and apex. 



Dimensions: Female — length, .87 in.; elytra equal the body; posterior 

 femora, .53 in. ; posterior tibia?, .47 in. 



I have found this species only in Colorado, east of the mountains. 



A very common species in the western part of the state but gradually 

 becomes less numerous as we go east, while the color variants of this 

 species, M. kiowa obliterata and M. kiowa thomasi appear and gradually 

 grow more numerous.

Body. Tegmina. Post, femora. 



Female 27.0-21.0 24.0-19.0 15.0-11.0 



Male 17.5-14.0 18.0-15.5 12.5- 9.5 



This species is easily separated from the two color variants by the 

 fact that the wing is entirely free from coloration. 

 (See fig. 67, page 79.) 



Mestob.regma kiowa var. obliterata Bruner. 

 Very similar to M. kiowa, but differing from that species in that the 

 basal disk of the wing is yellow, while in that species it is hyaline. 

 There is also a faint trace of the spur of the black arcuate band. The 

 band itself has entirely disappeared. This fact is the separating charac- 

 ter between this variant and the other color variant, M. kiowa thomasi.

Mestobregma kiowa var. Thomasi Caud. 



This species is in every way identical with kiowa, with the exception 

 of the coloration of the wing. The base of the wing is yellow; arcuate 

 band black with a spur, whole band receding basally in the region of the 

 spur; apically the wing is hyaline, slightly infuscated. 



This species is easily separated from plattei Th. by the shape of the 

 arcuate band, general size, and coloration of the whole insect. The wing 

 coloration also separates it from M. kioiva and M. kiotva obliterata.
