narrow pale median stripe; species not cave 

 inhabiting. 



n. Hind femora stouter and shorter, not over 

 four times longer than broad; supra-anal 

 plate short oval or subcircular, concave only 

 at center, its hind margin not broader than 

 the middle (PI. VII, a.) 301. GRACILIPES. 

 nn. Hind femora very slender, more than five 

 times as long as broad; supra-anal plate fan- 

 shaped, concave across its full width, the 

 hind margin much broader than the middle. 



301a. HERDS 



mm. Fore femora three-fourths or more longer than 

 pronotum; teeth of ovipositor suddenly con- 

 stricted at middle, their apical halves very 

 slender; antenna; of males four or more times 

 the length of body; hind tibise straight; tho- 

 racic segments never with a pale median 

 stripe; cave inhabiting species. 302. STYGIUS. 

 fcfc. Subgenital plate deeply and narrowly cleft without a 

 wide V-shaped notch (PI. VI, li. i) ; middle of ninth 

 dorsal but feebly projecting beyond the eighth, 

 o. Hind femora of male armed with 25 to 30 small 

 subequal, unevenly spaced teeth on each lower 

 carina; subgenital plate narrow, deeply cleft, 

 each lobe ending in a short, cylindrical projec- 

 tion, these subparallel and subcontiguous their 

 tips curved outward (PI. VI, 7;.); teeth of ovi- 

 positor short, triangular, the basal one one-half 

 more distant from the second than the others 

 from one another. 303. TERRESTRIS. 



oo. Hind femora with eight to 15 unequal teeth on each 

 lower carina; subgenital plate broad, its lobes 

 feebly diverging to form a shallow apical notch, 

 which is not filled with a membrane as in k (PI. 

 VI, i.) 



p. Ovipositor with rather stout, triangular, nearly 

 equally spaced teeth, terminal hook short, 

 stout, feebly decurved; lobes of male subgeni- 

 tal with outer angles prolonged but not diverg- 

 ent; inner median spurs of hind tibia? nearly 

 one-half longer than basal joint of hind tarsus. 



304. LATIBULI. 



pp. Ovipositor with long, feebly curved, very slender 

 needle-like teeth, terminal hook very slender, 

 strongly decurved (PI. VII, s) ; lobes of sub- 

 genital plate with outer angles ending in short, 

 strongly divergent cylindrical projections (PI. 

 VI, i) ; inner median spurs of hind tibiae 

 shorter than basal joint of tarsus. 



305. c^cus.
