no. 1124. REl'ISIOy OF THE MELAXOPLISCVDDER. 253 



mina brownish fuscous, minutely flecked with fuscous in the interstices 

 of the crowded veins, obovate, well rounded, twice as long as broad, 

 lateral, widely separated, hardly longer than the prozona. Legs vari- 

 able in color but generally dull yellowish brown, the hind femora 

 generally bifasciate with fuscous above besides the black geniculatiou; 

 hind tibiae at base and at tip dull yellqw mottled with brown, the rest 

 purplish glaucous, the spines black beyond the base, nine to ten, 

 usually ten, in number in the outer series. Extremity of male abdo- 

 men hardly clavate, not at all recurved, the supraanal plate triangular 

 with slightly convex sides and acutaugulate apex, tectate but with 

 elevated lateral margins forming large lateral sulci, the median sulcus 

 deep, tapering, crossing the basal half of the plate; furcula consisting 

 of a pair of minute pointed projections overlying the submedian ridges 

 of the supraanal plate; cerci slight, styliform, slender beyond the 

 thickened base, then scarcely tapering, gently incurved, the tip bluntly 

 pointed; subgenital plate small, subcouical, of equal breadth, some- 

 what longer than the apical breadth, with a slight erect tubercle. 



Length of body, male, 10.5 mm., female, 16 mm.; antennae, male, 5.5 

 mm., female, 7 mm.; tegmina, male, 2.2 mm., female, 2.5 mm.; hind 

 femora, male, 8 mm., female, 10 mm. 



One male, 4 females. Fort Keed, Orange County, Florida, April 8-10, 

 J. H. Comstock; Jacksonville, Duval County, Florida, November, 

 Maynard (S. Henshaw). 



This is the smallest known species of Melanoplus. 



10. INOKNATUS SEBIES. 



The prozoua of the male is here distinctly longitudinal, and the 

 interspace between the mesosternal lobes in the same sex quadrate, 

 or feebly longitudinal. The hind margin of the pronotum is either 

 truncate or very broadly obtusangulate. The tegmina are abbreviate 

 and nearly as long as if not somewhat longer than the pronotuin, some- 

 times rounded and sometimes subacuininate apically. The hind tibiae 

 are generally green, and the species vary much in the number of spines 

 in the outer series, ranging from nine to fifteen. 



The supraanal plate is triangular and generally rather flat, the lateral 

 margins hardly elevated; the furcula may be either reduced to slight 

 prominences or produced as delicate spines crossing the basal fourth of 

 the supraanal plate; the cerci again vary considerably, being either 

 stout, strongly constricted in the middle and widely expanded apically, 

 or tapering to a half or two-thirds the basal breadth and then forming 

 a relatively slender, slightly decurved, compressed finger; the subgeni- 

 tal plate is narrower, generally considerably narrower, than long, with 

 angulate, slightly elevated and tuberculate extremity. 



The species are rather slender, of about medium size, and are three 

 in number. One occurs in Mexico, a second in North Carolina, and the 

 third in Illinois and Indiana.
