Four $ $ , October and November, 1908, and January, 

 1909, all by Schunke. 



The ventral armature of the posterior femora exhibited by 

 these four specimens is very variable, there being from one to 

 five spines on the inner margin and the same range on the outer. 

 The anterior femora are unarmed beneath on the caudal margin 

 and armed on the cephalic margin with from one to three short 

 spines ; the middle femora are unarmed beneath on the caudal 

 margin and also on the cephalic margin or armed there with a 

 single small spine. 



This somber colored long legged insect superficially resem- 

 bles very closely the following species. 



Leptotettix pubiventris Bolivar.

 (1881); Kirby, Syn. Cat. Orth., vol. ii, p. 339 (1906). 



One $ , October, 1908, one 9 , December, 1908, both by 

 Schunke. 



Except for sexual differences the female is essentially like 

 the male. There is some variation in the ventral armature of 

 the femora. Thus the right intermediate femora of the male 

 has a single ventral spine of considerable size while in all 

 others it is unarmed as in the type. The posterior femora have 

 from two to four ventral spines and in both specimens now 

 under consideration the anterior femora have but two ventral 

 spines. The anterior tibiae are a little shorter than indicated in 

 the original description of the species. The measurements of 

 the present pair are as follows : 



Length: pronotum, $ , 5.5 mm., 9 , B mm. ; anterior femora, 

 5,13 mm., 9 , 13.5 mm. ; posterior femora, S , 38 mm., 9 , 31 

 mm. ; tegmina, $ , 52 mm., 5 , 54 mm. ; ovipositor, 22 mm. 

 Width : pronotum posteriorly, $ , 4 mm., 9 , 4.5 mm. ; tegmina 

 about the apical sixth, the widest point, $ , 10.5 mm., 9 , 11 

 mm. ; posterior femora at widest point, $,9,4: mm. ; ovipositor 

 mesiallv, 3.75 mm.
