o. 1124. REVISION OF THE MELAXorU-SCrDDEK. 59 



Valley, Nevada, but preserved after long immersion in spirits, which, 

 until fresh specimens are obtained for study, I regard as belonging to 

 this species. They are, however, remarkable for the brevity of the 

 tcginina, which are only as long as the pronotum, and the species has 

 not been otherwise recorded from this region. They seem to represent 

 a short-winged form of this species, their tegmina overlapping like the 

 normal form and not lobate, as in the strictly brachypterous species of 

 this genus. 



2. HESPEROTETTIX MERIDIONALIS, new species. 

 (Plate IV, fig. 9.) 



This species differs but little from H. festivu-s, but has even more 

 strikingly contrasted colors, the green of which is deeper and of a 

 bluer tint and the femora are stouter. The face is yellow with a slight 

 greenish tint, coarsely and distinctly punctate with blackish brown; 

 the intercostal interspace below the antennae is heavily infuscated 

 and the usual short bar below the eyes is present; vertex yellow, the 

 fastigiuin heavily infuscated and behind it a widening blackish stripe, 

 posteriorly inclosing a median yellow thread; antennae fuscous, the 

 joints feebly and narrowly annulate with pale ferruginous. Pronotum 

 yellow, more or less olivaceous, and 011 the inetazona often heavily suf- 

 fused with bright ferruginous, all the transverse sulci and particularly 

 that close to the front margin heavily marked in black, which cuts the 

 heavy black-bordered mediodorsal yellow stripe; upper portion of the 

 lateral lobes more or less heavily marked with black on the prozona; 

 pleural sutures heavily marked in black. Tegmina of about the length 

 of the abdomen, bluish green, the discoidal and posterior ulnar veins 

 with a narrow pallid yellow stripe. Fore and middle femora dull ferru- 

 ginous; hind femora with the outer face dull greenish luteous, the 

 superior carina heavily necked and punctate with fuscous, and a faint, 

 broad, dull coral red, pregenicular annulation; hind tibiae greenish 

 blue, the spines white with black tips, the tarsi more or less testaceous. 

 Supraanal plate of male much as in H. festivus, the furcula consisting 

 of a pair of minute but boldly projecting rounded lobes, separated by 

 twice their own width; cerci slightly compressed, subconical, tapering 

 much more rapidly in the proximal than in the distal half, the latter 

 being nearly equal, the tip rounded but slightly produced and gently 

 incurved, the whole scarcely so long as the supraanal plate; infracercal 

 plates inconspicuous, apically tapering, almost as long as the supraanal 

 plate. 



Length of body, male, 21 mm., female, 26 mm. ; antennae, male, 8 rnin., 

 female, 7.75 mm. ; tegmiua, male, 15.5 mm., female, 20 mm. ; hind femora, 

 male, 12 mm., female, 15.7 mm. 



One male, 2 females. Guanajuato, Mexico, A. Duges (U S.N.M. [No.
