antennae and bore no label of any kind. It appeared value- 

 less, being in poor condition and wholly without data, and I 

 was tempted to consign it to the waste basket. Better judg- 

 ment prevailed, however, and it was stuck in one corner of 

 a drawer. 



Recently Mr. J. L. Webb gave me for determination a few 

 Orthoptera taken by him the past summer in Arizona. Among 

 them were two male specimens which I recognized as the spe- 

 cies represented by the female specimen above mentioned. 

 They belong to Scudder's genus Barytettix, described from 

 Lower California, and constitute a new species related to B. 

 crassus of San Jose del Cabo. I call the species borealis and 

 describe it as follows : 



Barytettix borealis, n. sp. 



Male. — Yellowish-brown, marked with black. Head very slightly 

 darkened above and with a distinct piceous postocular band, fading 

 below ; frontal costa very shallowly sulcate, more distinctly so at the 

 ocellus, the sides parallel ; pronotum brown above, becoming yellowish- 

 brown on the laterial lobes, the latter marked by a broad piceous band 

 which terminates at the posterior sulcus and is obliquely interrupted 

 anteriorly by a conspicuous light-yellow streak that almost or quite 

 completely severs it ; position of lateral carinse indicated by yellowish 

 slightly incurved lines which, like the piceous side bands, terminate at 

 the posterior sulcus. Anteriorly the pronotum is truncate and poster- 

 iorly it is broadly concave; epimera of the metapleura black. Tegmina 

 dark brown, apically rounded, widest beyond the middle, twice as long 

 as broad, about three-fourths as long as" the pronotum. Anterior and 

 intermediate femora uniformly yellowish brown, distinctly swollen; 

 posterior femora moderately heavy, lined with black above, the outer 

 face longitudinally marked with black, a broad stripe on the upper part 

 of the face and a narrower one below, the genicular arcs black; spines 

 of the posterior tibia short and black, 9-10 in outer series; claws black 

 in the apical half and the arolia are margined with black and about 

 half as long as the last tarsal joint. Abdomen with a light dorsal 

 stripe margined with black and each segment, especially the anterior 

 ones, marked with an elongate, triangular black spot. Subgenital plate 

 apically prolonged into a large tubercle, not so blunt as in B. crassus 

 as figured by Scudder; supraanal plate triangular, longitudinally con- 

 cave on each side of the middle, which is marked by a deep sulcus, 

 somewhat narrowed centrally and extending nearly to the tip of the 

 plate; furcula represented by a pair of short rounded lobes; cerci in- 

 curved, extending barely beyond the apex of the supraanal plate, 

 mesially narrowed to about two-thirds the basal width and then ex- 

 panded to a width somewhat greater than the basal width, the tip 

 truncate, the lower apical angle acute, moderately produced, the upper 

 apical angle rounded, not produced.
