General color seal brown and ochraceous, a distinct subequal median 

 line extending- from the fastigium to the extremity of the anal area of 

 the teg-mina. Head dark alK)ve, except for the median line, no distinct 

 postocular bar aside from the dorsal suffusion, a distinct infraocular 

 dark sutural line present in the male, unmarked in the female; eyes

 obliijue bar broken in the male, distinct in the female. Tegmina with 

 rather regular transverse bars, heavier and wider distad than proximad, 

 the anal area, except the median line, and angle very dark and hardly 

 maculate in the female. Caudal femora distinctl}' barred dorsad and

 dark bar wide, ventro-lateral carina beaded with the dark color, very 

 closely beaded in the male, pregenicular light annulus complete, 

 genicular region dark, ventro-lateral face very dark heliotrope purple,

Three paratypic males have also been studied (May and flune). 

 These present a great amount of color variation, chiefly, however, in 

 the intensity. The suffusion of the dorsum of the head is limited in 

 some and distinct postocular bars present; the median line is obsolete 

 on the anal area of the tegmina in several, and in these specimens the 

 angle of the tegmina bears a pale line; while several specimens have 

 the lateral lol)es with large strongly contrasted blotches of color 

 instead of small irrogularly distributed spots. 



SCYLLINA SCHISTOCERCOIDES, new species. 



Ti/pe. — Female; C'hapada, Matto Grosso, Brazil. (H. H. Smith.) 

 [Cat.No. J>485, U.S.N.M.] 



Closely allied to X. horreJlH Giglio-Tos, from the Rio Apa region, 

 Paraguay, but much smaller and with other differences, such as the 

 distinct blackish blotches on the lateral lobes of the pronotum. 



Size rather large; form rather slender and suix'rticially resembling 

 species of the genus Schistocerca. Head somewhat ascending; fas-
