what differently shaped and colored. In the present insect, the entire 

 costal margin of the tegmina is rather widely ivory white bordered 

 behind by a conspicuous line of purple, and the costal field has fewer 

 and more regularly arranged oblique white lines, while above or back 

 of the radials the pale oblique marks are very dim or even almost 

 obliterated, and the hind or dorsal margin is narrowly infuscated. 

 The disc of the pronotum has its margin defined by carinae, which 

 are simply arcuate instead of sinuate, and the lateral lobes are much 

 higher behind than in front. The auditory opening is black with 

 the base of the anterior tibiae dark vinaceous. 



Length of body, cf , 19 mm., of pronotum, 4.1 mm., of tegmina, 

 cf , 29 mm., of hind femora, 22 mm. 



Habitat. — The two males at hand come from Puerto Suarez, Bolivia, 

 where they were collected during November at an elevation of 150 

 meters above sea-level. (J. Steinbach.) The type is in the Carnegie 

 Museum. 



Genus Enthephippion gen. nov. 



Related to Insara Walker {Hormilia Stal) in its structural features 

 as shown by the synopsis of genera given on preceding pages of the 

 present paper. It also bears some resemblance to Gynuiocera Serville, 

 especially in colorational features and in the structure of the ovipositor. 



The representatives of the present genus are rather small to medium 

 in size. The head is a little wider than the anterior margin of the 

 pronotum, the front perpendicular, sides parallel, the occiput short, 

 rounded; fastigium of the vertex somewhat depressed, sulcate, blunt 

 at apex and not quite touching the fastigium of the front; eyes moder- 

 ately prominent, a little longer than wide. Pronotum with the disc 

 somewhat narrowed anteriorly, the lateral angles blunt, anterior 

 margin truncate, rounded behind, lateral lobes roundly inserted, the 

 lower and posterior margins evenly rounded. Tegmina narrow, con- 

 siderably longer than the abdomen and hind femora, their apex 

 rounded; wings reaching beyond the tegmina by at least the width 

 of the latter. Anterior and middle, as well as posterior femora, spine- 

 less beneath; anterior and middle tibiae sulcate above, the latter 

 spined on the inner margin near its middle. Ovipositor moderately 

 robust, curved, and strongly dentate both above and below, as well 

 as on the carinte of the lateral disc. Antennae filiform, not robust.
