434: FAMILY VI. ACRIDID/E. THE LOCUSTS. 



tegmina immaculate, male, very faintly flecked with fuscous, fe- 

 male; scoop of upper valves of ovipositor very short, the base of 

 their outer edges entire (Fig. 144, d.) 203. COXFUSUS. 



aa. Forks of cerci usually distinct, the lower one the narrower; furcuhi 

 minute triangular lobes, shorter than last dorsal segment. 

 (PI. IV, o.); median area of tegmina slightly maculate with fus- 

 cous; scoop of ovipositor longer, the outer basal margin crenulate 

 (Fig. 144, c.) 



1). Subgenital plate of male longer than broad; upper fork of cerci 

 strongly oblique, scarcely bent upward (Fig. 145, d) ; lower 

 valves of ovipositor relatively long, almost straight; females 

 rarely under 26 mm. in length. 204. KEELEEI. 



l)b. Subgenital plate as broad as long; upper fork of cerci bent dis- 

 tinctly upward (PL IV, o) ; lower valves of ovipositor relatively 

 short, distinctly decurved (Fig. 144, c) ; females rarely over 

 25 mm. in length. 204a. LUKIDUS. 



203. MELANOPLUS CONFUSUS Scudder, 1897b, 29. Little Pasture Locust. 



Size medium for the genus, small for the group, the sexes subequal. 

 Above, dark brownish or fuscous, often with a reddish-brown tinge; be- 

 low dull yellowish. Occiput and disk of prozona darker than metazona; 

 the usual shining black bar on upper third of lateral lobes of prozona, 

 small in male, often broken or subobsolete in female, bordered below with 

 brownish-yellow. Hind femora brownish-yellow, lower face reddish-orange; 

 knees black above. Hind tibia? usually pale blue, pinkish at tip, some- 

 times red or dull yellow; spines black. Interocular space nearly twice, 

 male, or three times, female, as wide as first joint of antennae; fastigium 

 but feebly declivent, distinctly and widely sulcate in male, depressed but 

 scarcely sulcate in female, the lateral margins sharp. Frontal costa faintly 

 narrowed between the antennae, feebly sulcate at and below the ocellus. 

 Pronotum short, but slightly widening on metazona; hind margin broadly 

 obtuse-angled; median carina low, visible throughout, a little less distinct 

 on prozona; -disk of prozona broadly convex, a fourth longer than the finely 

 punctate metazona. Tegmina reaching tips of hind femora, female, 

 slightly surpassing them, male, of nearly equal width throughout. Supra- 

 anal plate short, broad, triangular, the apex acute; median sulcus rather 

 wide, confined to basal half. Furcula consisting of a pair of well separated 

 parallel cylindrical spines about a fourth the length of supra-anal plate 

 and overlying the ridges of its median sulcus (PI. IV, n.) Cerci with basal 

 portion stout, rectangular; apical portion nearly as long but narrower, 

 bent slightly upward and inward, its dorsal margin rounded and outer face 

 concave, an inferior angle or process at point of bend; the apex broadly 

 rounded. Subgenital plate very short, apex rounded, the lateral margins 

 incurved near base; apical margin thickened and slightly prolonged. 

 Length of body, $, 1618, 9, 19 24; of antennae, $, 78, 9, 89; of 

 pronotum, $, 4.5, 9, 5; of tegmina, $, 11 15, 9, 14 17; of hind femora, 

 $, 1011.5, 9, 1213.5 mm. 



In Indiana this appears to be one of the least common of the 

 Melanopli, having been noted only in Monroe, Vigo, Putnam and 

 Marion counties. It has been found in numbers bnt once, on June
