 shorter than the third, rarely thicker than that joint. Thighs 

 not spinous beneath at the apex ; hinder thighs not thickened. 

 Abdomen ovate, projecting considerably beyond the elytra on 

 each side*. Membrane with numerous nervures.

TABLE OF GENERA. 



I. Antennae cylindrical. 



A. Thorax crescent-shaped. 



a. Body elongate; abdomen not dilated. 1. EUAGONA. 



b. Body ovate ; abdomen dilated beyond 



the elytra on each side 3. MENENOTUS. 



B. Thorax unarmed, or with the lateral 



angles simply prominent 2. SPARTOCERA. 



II. Antennae with the second and third joints 



compressed and slightly dilated 4. ACANONICUS. 



Genus 1. EUAGONA, n. g. 



Head square, with the antenniferous tubercles very long and 

 contiguous, obliquely truncated at the apex. Ocelli distant. 

 Antennae long and slender, very nearly as long as the body, of 

 four joints ; basal joint stoutest, obliquely truncated at the base, 

 a little shorter than the second ; second longest ; third shorter 

 than the first, thinner than the second ; fourth shortest, thinner 

 than the third. Rostrum reaching the middle of the mesoster- 

 num, inserted about the middle of the under side of the head ; 

 basal portion of the basal joint enclosed in a canal ; second joint 

 shorter than the third; fourth longer than the third. Body 

 elongate, with the sides nearly parallel, a little narrowed behind ; 

 margins of the abdomen a little flattened, but not projecting be- 

 yond the elytra. Thorax produced on each side into a long, ta- 

 pering, acute, curved horn, directed upwards and forwards ; la- 

 teral margins unarmed; posterior margin rounded. Scutellum 

 small, triangular. Membrane of the elytra rather smaller than 

 the coriaceous portion, with numerous longitudinal nervures. 

 Legs very long, especially the posterior pair, the tibiae of which 

 are longer than the thighs ; tarsi long, of three joints ; basal joint 

 longer than the other two together; second joint shortest; claws 

 small. 



* The genus Euagona is an exception to this character, but in other 

 respects it is so evidently allied to the other members of this family, 

 that I have thought it best to place it here.
