Melanoplus strumosus sp. nov. 



A small species with verj small ovate tegmina, attingent in male, a little separated in 

 female. Disk of pronotum twice (male) or once-and-a-half (female) as long as wide, mid- 

 carina percurrent, lateral carinae barely perceptible mesially. Prosternal spine prominent, 

 flattened cylindric, slightly curved backward, apex transversely excised, the angles rounded. 

 Mesosternal interspace quadrate in female, slightly longitudinal in male. Metasternal inter- 

 space longitudinal, twice as long as wide (female), narrower in male. Tegmina obovate, 

 two-thirds as long as pronotum. Hind femora stout, very obliquely bifasciate with fuscous. 

 Hind tibiae glaucous, flavescent at base and tip, with black-tipped spines. 



Male abdomen subclavate, the subgenital plate and preceding segment tumescent, 

 broader than deep, and greatly elongated, the former elongate scoop-shaped, bluntly rounded 

 at apex, its sides a little convex, especially at base. Supra-anal plate broader than long, 

 somewhat trilobate at end by reason of deep, subapical lateral emarginations, the apex 

 acutely pointed with straight sides, the basal three-fourths of each side smoothly convex, 

 curving abruptly into the subapical emarginations. Its upper surface bears strongly raised 

 edges and a prominent transverse ridge midway of its length, crossing two-thirds of its 

 width. To this ridge extend, lying upon longitudinal ridges, the processes of the furcula ; 

 these are very broad at base, tapering equally to digitate, apically sinuate, tips which rest 

 upon the ends of the transverse ridge, and enclose between them the shallow median sulcus, 

 wide apically, narrow anteriorly. The base of the furcula and median portion of the 

 segment bearing it are distinctly depressed ; the median portion of the preceding segment is 

 depressed to fit into this hollow, slightly elongated, widely and shallowly sulcate longitudi- 

 nally, the sulcus transversely rugulose, with apical margin carinate opposite base of furcula. 

 Cerci short and slender, about two-thirds as long as supra-anal plate, nearly three times as 

 long as basal width, tapering evenly in basal half to one-fourth the basal width, distally bent 

 gentlv upward and inward, the tip slightly expanded to about one-third the basal width, 

 obliquely excised, the upper angle rounded, the ventral acute, the ventral margin convex or 

 sinuous, the dorsal margin concave. 



General color deep reddish brown above, whitish or flavescent beneath. Post-ocular 

 fuscous stripe indistinct in female, deep black in male, percurrent, extending to abdomen, 

 even suffusing the metepisternal pale fascia.

Melanoplus tribulus sp. nov. 



A short-winged species of medium size. Disk of pronotum somewhat convex above, 

 once-and-a-half (female) or twice (male) as long as wide, mid-carina percurrent, distinct, 

 lateral carinae obsolete, hind margin a little convex, emarginate. Prosternal spine promi-
