66 NEW NORTH AMERICAN ACRIDID.E BRUNER. 



Vertex deeply and roundly sulcate, the bounding walls continuous 

 with those of the frontal costa, the fastigium furnished with a rather 

 deep V-shaped depression, from the apex of which a median carina ex- 

 tends backwards through the sulcus and across the occiput ; lateral 

 foveolae rather large and shallow; froutal costa quite prominent, widen- 

 ing below. The sides a little contracted just below the ocellus, deeply 

 sulcate throughout. Pronotum rather smooth. The anterior lobes 

 combined about one-half as long as the posterior lobe; median cariua 

 twice notched, nearly equal throughout ; posterior extremity about a 

 right angle; lower lateral tooth less elongate thau in C. albolineata. 

 Tegmina long and narrow, reaching about one-fourth their length be- 

 yond the tip of the abdomen. Posterior femora rather robust, with the 

 carinas inconspicuous. 



General color cinereo-testaceous, profusely and heavily mottled with 

 dark brown and black. Antennae black, annulate with testaceous. 

 Tegmina testaceous on lower or anterior half, dirty white above, very 

 heavily and profusely mottled with black. These spots not congre- 

 gating in bands. Wings sulphur-yellow on basal half, crossed by a 

 broad, arcuate, black band that sends a wide ray halfway to the base 

 near the anterior edge; apical third hyaline, with two pretty well de- 

 fined longitudinal black rays reaching from the extreme tip nearly to 

 the outer edge of the band, most apparent in male specimens. Pos- 

 terior femora light testaceous, with two dark patches above and an 

 outer face, also some dots of same color along the carina* ; posterior 

 tibiae pale coral red with a wide white basal anuulus.

Conozoa albolineata sp. nov. 



Rather slenderer than the other species of the genus. Grayish-brown 

 streaked with white. 



Vertex somewhat elevated ; fastigium as in G. sulcifrons, continuous 

 with the deeply sulcate frontal costa, which expands evenly and gradu- 

 ally to the clypeus; eyes of medium size, slightly prominent, separated 

 above by about their width; antennae as long as the posterior femora; 

 pronotum quite smooth in comparison with that of C. sulcifrons and C. 

 wallula, considerably depressed at last transverse sulcus, from which 

 point it expands and ascends quite rapidly posteriorly; median carina 

 not prominent but visible throughout, twice notched, anterior por- 

 tion most elevated, lateral carnia3 slight, only noticeable on the posterior 

 lobe, posterior angle a little less than a right-angle. Tegmina ex- 

 tending about one-fourth their length beyond the tip of the abdomen, 

 slender.
