Siibgenital plate roughly scoop-shaped, with two heavy, rounded earinae con- 

 verging distad to the bases of the small styles. Styles cylindrical, three 

 times as long as wide, separated by a distance one and one-half times as long as 

 one of them; the emarginate caudal margin of the supra-anal i)Iate in this in- 

 terval has the sides straight convergent, the basal jwrtion, which is of sliglitly 

 greater length, transverse. 



Limbs with hairs as in calliincra. Cei)halic and median femora with ven- 

 tro-cephalic margin armed with a single small spine. Caudal femora with 

 ventral margins armed with (four and five) external and (three and four) in- 

 ternal small spines. Genicular lobes of femora unarmed, except the cejihalic 

 of the cephalic femora and the caudal of the median femora, which bear a 

 single small s]:)ine, and the cephalic of the median femora, which bears two 

 still smaller spines. Cephalic tibia with dorsal surface armed with three 

 spines along the caudal margin. Caudal tibiae armed with three pairs of 

 elongate tlistal spurs, of which the medio-internal is the longest, as long as 

 the dorsal length of the metatarsus,^" the medio-external two-thirds as long, 

 the dorsal pair each two-thirds as long as the medio-external. Plantula about 

 half as long as metatarsus. 



General coloration ochraceous-buff, very finely marked with blackish 

 brown around eyes and dorsal portion of internal margin of convex callos- 

 ities of lateral lobes. Tegmina immaculate. Abdominal tergitcs with cau- 

 dal margins showing very small lateral and dorsal flecks of blackish brown, 

 and intervening dots of lighter brown of still smaller size. Cephalic and 

 median limbs and caudal femora flecked at base of each spine with blackish 

 brown. 



Length of body, 19.5 mm., length of pronotum,.5.2; total width of pronotum, 

 5; length of exposed portion of tegmen, 3.7; length of cephalic femur, 5.2; 

 length of median femur, (>; length of caudal femvu", 10.;^; length of caudal 

 tibia, 20. 



The type is unique. 

 Idiostatus callimera-' new species (PI. X, figs. 9, 10, 11 and 12.) 



This handsome species is readily recognized l^y its striking 

 coloration, the markings of the caudal femora Ijeing particularly 

 distinctive. 



The coloration of the pronotum is such that the disk appears 

 to ])e sharply divided from the lateral' lol)es, but this is more 

 apparent than real, the lateral carinae being well developed only 

 in the caudal portion and much as in /. inermis (Scudder). We 

 emphasize this feature as a superficial examination might easily 

 lead one to believe these carinae to l^e percurrent and more sharply 

 defined, as in Idionotus brunneus Scudder, than they actually are. 



^ The metatarsus in this species is longer than in caUiiiieni, tl)e longest spur 

 decidedly longer, with shaft straighter than in that species. 

 ^^ From KaXXt-txfjpa = beautiful thighs.
