Although by the use of the table for separating the genera 

 of the sub-family Acridiinae found in Argentina the two 

 following species will fall in the genus Jodacris, they differ 

 considerably from the insect upon which the table was 

 chiefly based ; and, perhaps, form a new genus which would 

 be separated from the preceding in having the body some- 

 wiiat slenderer, the pronotum more expanded posteriorily, 

 the head proportionately smaller, H intead of 7 spines in 

 outer row of hind tibiae, and the abdomen compressed rather 

 than cylindrical as indicated for the genus in which they are 

 placed. In looking over the description of the genus Jodacris 

 as given by Giglio-Tos, it appears evident that he had before 

 him a male of the insect mentioned as J. fernu/hiea, and a 

 female of the one named here J. (V) nehulom, hence the 

 agreement of the generic description of Jodocris with the 

 present insects. 



Jodacris (?) itcbulosa n. sp. 



General color dull ferrugineo-fuscous, with the face, lower 

 and ujDper edges of sides of pronotum, together with an 

 oblique line on meso- and metapleurae somewhat lighter; 

 tegmina obscurely mottled with dark brown or dull black. 

 The hind femora marked with two dusky bands across the 

 upper edge and extending to the inner face; the lower 

 external edge also black. Posterior wings clouded apically, 

 bright bottle green basally. Sides of pronotum a little above 

 the middle with a more or less well marked oblique dusky 

 band which is continuous with that back of the eyes and 

 below the light colored oblique band of meso-and metapleurae. 

 Posterior tibiae obscure grayish blue, more or less mottled 

 with black, paler basally. Pronotum expanding posteriorly, 

 the three transverse sulci profound ; median carina present 

 on front edge of anterior and on posterior lobes ; the anterior 

 edge gently emarginate, and posterior edge broadly angulate. 

 Upper valves of female ovipositor moderately long, acuminte, 

 the edges crenulate before the apex. Circi of male compress- 

 ed, rather broad basally. beyond slender, quite long, gently 

 curved inwai'd, the apex forked, tlu^ inner prong slightly the
