a granular appearance, narrowed anteriorly, a little longer than the 

 occiput back of them; the basal antennal joint robust and provided 

 at its apex internally with a blunt tooth. Pronotum very similar 

 to that of the other described species, nearly twice as long as wide, 

 the anterior margin nearly straight, the hind margin sinuate, but to 

 a less degree than in N. meridionalis, the rugose border narrower than 

 in that species. Tegmina about as long as the abdomen, the vena- 

 tion regular, none of the veins especially prominent, as is the case 

 in this sex of N. meridionalis where several of the oblique veins are 

 much heavier than the others, on the costal field also quite regular; 

 wings lengthily caudate, extending beyond the tegmina a distance of 

 about two-thirds the tegminal length. Legs very slender, the hind 

 tibiae entirely destitute of spines on their margins; anterior tibiae 

 perforated on both sides, as in both of the other species, their basal 

 half f usiformly dilated. Cerci sinuose as described for N. meridionalis, 

 and as also in bipunctata . Ovipositor slender, a little shorter than the 

 hind femora. 



General color uniformly pale fiavo-testaceous with the exception of 

 the front and occiput, which is dark, varying from brown between 

 the base of the antennae to deep pitchy black on the occiput. In the 

 middle of this dusky area is a narrow median longitudinal flavous 

 line, and at either side of it is a little wider gray one composed of a 

 scale-like covering or pruinescence on the dusky background. 



Length of body, 9 , 12 mm., of pronotum, 2.7 mm., of tegmina, 

 9.5 mm., of hind femora, 7 mm., of ovipositor, 5 mm. 



Habitat. — Rio de Janeiro, Brazil, in October (H. H. Smith), two 

 females. These insects are the property of the Carnegie Museum. 



70. Neoxabea meridionalis sp. nov. 



About the same in size and general form as N. bipunctata DeGeer, 

 but without the well-defined black dots on the tegmina, which are so 

 prominent in that species. General color rusty testaceous, the prin- 

 cipal veins of the tegmina, especially the oblique ones and the cross- 

 veins near the base, knees, and tarsi of all the legs, stained brown, in 

 some specimens inclining to black. 



Head a little broader than the front edge of the pronotum, fully as 

 long as the pronotum, when the mouth is directed forward, the eyes 

 as long as the occiput back of them. Basal antennal joint large and
