130 OETHOPTEEA. 



General colour above light greyish-brown, profusely and rather evenly mottled and streaked with dark brown 

 and dull black; below pale testaceous, the dorsum of the abdomen bluish-tinged. Dorsum of the 

 prothorax obscurely decussate with paler, the sides and the head back of the eyes longitudinally 

 streaked alternately with darker and paler dashes of brown and grey. Tegmina with the dorsal edge 

 paler and nearly destitute of the otherwise rather general dusky markings. Wings transparent greenish- 

 yellow on the disc and along the anterior field nearly to the apex, the latter portion vitreous ; the 

 fuliginous band rather broad, but pale, and broken by the radial veins, not quite reaching the anterior 

 edge ; taenia quite prominent and reaching nearly to the base. Hind femora thrice obliquely banded 

 with fuscous, internally black, banded with testaceous, below blue-tinted ; tibiae bluish, with a rather 

 broad pale basal annulus, the tarsi testaceous. 



Length of body, d 21, $ 29 ; of antennae, J 7, $ 7'5 ; of pronotum, 3 4-85, $ 55 ; of tegmina, c? 23, 

 $ 25 ; of hind femora, J 12, $ 15 millim. 



Hab. North America, Huachuca Mts., and Nogales, Arizona (coll. U.S. Nat. 

 Mus. ; R. E. Kunze :<?$). 



This insect reminds one very much of some of the pale-winged species of Trimero- 

 tropis, to which, at first sight, it bears a strong resemblance. A. aberrans seems to be 

 rather local in its distribution, but may occur across the boundary-line in Mexico. 

 Three specimens.]

A species somewhat resembling A. teporata, Scudd., but differing from it in having 

 the fuliginous band of the wings much more strongly indicated, and more especially 

 in having the apices of the latter strongly suffused with fuscous. As compared with 

 A. nietana, Sauss., it is more slender, the vertex is narrower, the face is more vertical, 

 the metazona of the pronotum is longer, and the hind femora are less robust. A. canora 

 will surely be found to occur in the mountains of Northern Sonora and Chihuahua.]

This species probably occurs also in the mountains of Northern Chihuahua. The 

 characters which separate it from the other members of. the genus are given in the 

 synoptic table. It is rather northern in its distribution, as compared with A. teporata
