Kirby has already synonymized brevis and Stal's subnotata from 

 the Philippines. Burmeister's gracilis is not preoccupied by 

 gracilis of Germar, 1817, as supposed by Karny, 37 Germar having 

 described a Locusta gracilis. 



MECOPOD1NAE 



After careful consideration of the literature and comparison of 

 the species before us, we believe it best to follow Bolivar's arrange- 

 ment of the sections and genera of this subfamily. 38 The remark- 

 able development of the pronotum in the Section Phyllophori does 

 not, in our opinion, warrant its recognition as a distinct subfamily. 39 

 The Sections Phrictae and Segestini 40 are, indeed, both more widely 

 divergent from the Section Mecopodi. 



Section PHRICTAE 

 CHLORACANTHA new genus 



This genus is based on a single remarkable species here described, 

 differing in a number of important features from the other genera 

 of Section Phrictae. In fact the wholly unarmed femora and 

 caudal tibiae, which are armed distad with a single small pair of 

 ventral spurs, may oblige placement of this insect in a section of 

 its own. The single species known is of very small size for the 

 Subfamily. 



Genotype. — Chloracantha lampra new species. 



Antennal scrobes very large, their margins moderately produced 

 latero-ventrad and produced, attingent and rounding dorso-mesad; 

 thus with narrowly triangular, sulcate vertex fitting tightly between 

 them dorsad and the very narrowly triangular facial fastigium 

 similarly fitting tightly between them on the cephalic face. Eyes 

 globose and very prominent. Antennae very long, with proximal 

 joints smooth. Frons reclinate, smooth, slightly higher than wide. 

 Pronotum with disk flat, the two transverse sulci straight and deep, 

 with a weakly indicated medio-longitudinal sulcus; cephalic and 

 caudal margins of disk both very feebly convex and nodulose, 

 lateral margins straight, nearly parallel, armed with large, rounded 

 spines. Lateral lobes of pronotum vertical, decidedly longer than

 Moristini to the Segestini.
