DESCRIPTIONS O^F MflT NEW ORTHOPTERA, AND NOTES ON 

 SOME SPECIES BUT LITTLE KNOWN. B\ CYRUS THOMAS. 



Minorissa alata, sp. nov. 



Corresponds very closely with Walker's description of M. pustulata, 

 except that the wings are fully developed and nearly as long as the 

 elytra. 



The sides of the pronotum are not tuherculate except the slight tu- 

 bercles along the lower margin. Color uniform pale-green. 



The following additions may be made to Walker's generic characters : 

 Posterior femora shorter than the abdomen, triangular; head slightly 

 ascending. 



The anterior and middle transverse lines of the pronotum are nearly 

 obsolete in the single specimen I have examined. 



Dimensions. — 9 , Length, 1.4 inches; elytra, 1 inch; posterior femora, 

 0.52 inch; posterior tibia, 0.50 inch. 



Habitat unknown ; the specimen, which is somewhat mutilated, found 

 in the collection at the Agricultural Department, without any mark 

 indicating the place where it was obtained. It is probably from some 

 part of South America. 



Opomala niexicafia, Sauss., Eev. et Mag. Zool., XIII (1861), 156. 



Slender, cylindrical elongate. 



Female. — Occiput somewhat elongate, slightly ascending, with a shal- 

 low punctured sulcus each side, the two approaching in front. Vertex nar- 

 row between the eyes, expanding in front of them, rounded in front, this 

 portion being about as broad at the base as it is long ; a shallow channel 

 along the middle; margin not raised. Eyes very oblique, oblong, ovate. 

 Face very oblique; the middle pair of carinte distinct above, somewhat 

 fading below ; lateral pair indistinct. Antennte rather short, enlarged 

 at the base, but somewhatthick and but slightly flattened ; edgesrounded. 

 Pronotum a little longer than the head, cylindrical, without carinse; sides 

 parallel; transverse incisions minute and indistinct; the posterior one 

 about two-thirds the length from the front ; posterior margin obtusely 

 rounded ; its entire surface, as also the top of the head, minutely granu- 

 lose. Elytra elongate, passing the abdomen about one-third their length ; 

 very narrow and lanceolate; wings nearly the same length. Posterior 

 femora reach the tip of the abdomen 



Color (dried). — Pale olive-brown, with a yellow stripe commencing at 

 the lower angle of the eye and running along the lower margin of the 

 side of the pronotum to the insertion of the posterior leg ; this yellow 

 margin or fascia each side is very distinct and marked; otherwise the 

 color is somewhat uniform, except the posterior tibiae, which are blu^. 



Male. — Differs from the female in being smaller, slenderer, and as fol- 

 lows : The vertex is more pointed ; the transverse incisions of the pro- 

 notum almost wholly obliterated ; the elytra almost linear ; the subanal 

 plate elongate, pointed, curved upward; the pinnae of the posterior 

 femora dim, and scarcely V-form ; the posterior femora scarcely as long
