minii brownish fiiacoiis, miiintelv flecked with fuscous in the interstices 

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

 lateral, widely separated, hardly lonjj^er than the prozona. Legs vari- 

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

 generally bifasciate with fuscous above besides the black genicuhition; 

 hind tibiae at base and at tip dull yellow 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 acutangulate apex, tcctate but with 

 elevated lateral margins forming large lateral sulci, the median sulcus 

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

 of a pair of minute pointed prqjectious overlying the submedian ridges 

 of the supraanal i)late; cerci slight, styliform, slender beyond the 

 thickened base, then scarcely tai)ering, gently incurved, the tip bluntly 

 jtointed; subgenital plate small, subconical, of ecjual breadth, some- 

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



Length of body, male, 10..") mm., female, KJ mm.; antennae, male, .>.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, Fhnida, April 8-10,

This is the smallest known spe(;ies of Melano^lun,

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

 interspace between the mesosternal lobes in the same sex (piadrate, 

 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 pronotum, some- 

 times rounded and sometimes subacuminate ajucally. The hind tiojae 

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

 ill the outer series, ranging from nine to fifteen. 



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

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

 jirominences or produced as delicate spines crossing the basal fourth of 

 tlie 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 tinger; the subgeni- 

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

 aiigulate, 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.
