Bruner : South American Acrj »ea. S'i 



pronotum combined, the basal joinl quite large, nearly as greal in 

 diameter as the width of the vertex between the top extremity of the 

 eyes, twenty-one-jointed. Pronotum cylindrical, quite strongly punc- 

 tulate, most closely so on the hind lobe, on the upper field of the 

 lateral lobes provided with two rather large quadrate glabrous pat< 

 anterior and posterior margins of disk broadly rounded, the middle of 

 hind edge a little emarginate; the three transverse sulci continuous, 

 the posterior one most profound, the hind lobe slightly less than one- 

 half the length of the front lobe. Tegmina and wings somewhat 

 shorter than the abdomen, reaching to the posterior extremity of the 

 sixth abdominal segment, the apex of the former rounded. Hind 

 femora quite large and robust, somewhat passing the tip of the 

 abdomen; the hind tibiae quite conspicuously expanded apically, 

 their lateral edges strongly acute, seven-spined externally, ten-spined 

 internally. Prosternal spine slender, erect, the apex acuminate and 

 diii (led very gently to the front. Mesosternal lobes not touching 

 on their inner edges, the space about half as wide as long. Valves 

 of the ovipositor moderately long, the upper pair straight, robust, 

 but little tapering, the apex obliquely docked, the outer margin 

 finely serrate; lower pair slenderer, the outer third tapering and gently 

 hooked, the outer margin also more or less closely serrate. Under- 

 side of apical segments and valves of ovipositor strongly hirsute. 



General color above brunneo-testaceous, the sides back of eyes 

 piceous; below testaceous or flavous; hind femora olivaceous, above 

 and externally, inside and below pale flavous; hind tibiae pale glau- 

 cous, the apical half of spines black; the tarsi infuscated. Antenna? 

 greenish at base, becoming strongly infuscated on apical half, the 

 extreme apex dirty white. 



Length of body, 9 , 26 mm., of pronotum, 5 mm., of tegmina, 

 13 mm., of hind femora, 15.5 mm.

Chlorohippus gen. nov. 



Related to both Chrostheipus Brunner v. Wattenwyl and Copiocera 

 Burmeister, but differing from both of these genera as well as from 

 Kpiprora Gersta'cker in a number of respects. General form moder- 

 ately robust, subcylindrical, the head, pronotum, and pleura densely 



and strongly punctulate, the former less densely so on occiput ; anterior
