LEIOTETTIX SANGUINEUS, new species. 



A slenderer insect than either viridis or punctijMs, but to both of 

 which it is rather closely related. Its determinate characters are well 

 defined dark g-reen pronotal stripes and deep blood-red inside and lower 

 edge of hind femora. The sides of face below the eyes and lower half 

 of sides of pronotum are flavoiis, as are also a portion of the pleura, 

 venter, and lower part of outer face of hind femora. Above, the 

 general color is ferruginous, in some specimens with an olivaceous 

 tinge near the base of tegmina. Costal field of latter olivaceous, as are 

 the anterior and middle legs, along with the outer disk of the hind 

 femora, the latter without dusky spots on the carina?, as described in 

 punctipes. The hind tibite deep glaucous. Male cerci similar to those 

 of mridls. Sides of the four basal abdominal segments largely jet 

 black. Median carina of pronotum plain throughout. 



Length of body, male, 18, female, 25; of pronotum, male, 4, female, 

 5; of tegmina, male, 14, female, 16-18; of hind femora, male, 9.5, 

 female, 13 mm.

Habitat. — Sapucay, Paraguaj^, January to March, 2 males and 2 

 females. Taken by W. T. Foster. 



LEIOTETTIX FLAVIPES, new species. 



In general structure and appearance quite similar to the other species 

 of the genus described above, but differing from all of them in the 

 larger size and the more decided dark pronotal bands. It also reminds 

 one of the species of Scotussa, but it lacks the pale dorsal vittae of both 

 S. 7nibripes and S. hrasiUe7isls, to which it approaches in size. As 

 compared with them it has the head larger, the occiput shorter, the 

 vertex broader and less deeply sulcate, the eyes less elongate and 

 pointed above, the frontal costa broader above and more uniform in 

 width, as well as decidedly sulcate in the vicinity of the ocellus. The 

 pronotum is slightly contracted at the middle and the head is a trifle 

 wider than its front edge — the sculpturing, punctation, and arrange- 

 ment of the sulci are the same, only the present species lacks the piceous 

 bands on head and sides of pronotum back of the eyes, and in their 

 stead has them deep green in color. The color of tegmina, body, and 

 legs are similar, save that in the insect now under consideration the 

 hind tibiffi are testaceous instead of green or coral-red. In some speci- 

 mens the lower sulcus and inner face of the hind femora lack the bright 

 red of hrasUiensis especially. 



Length of body, male, 24, female, 28-31; of pronotum, male, 4.85, 

 female, 6-6.5; of tegmina, male, 19, female, 20-21; of hind femora, 

 male, 12.25, female, 15.25-16 mm.
