1. Euxenica aptera sp. no v. 



General color of body testaceous to ferrugineo-testaceousj the 

 tegmina grass-green; lateral carinae of the pronotum and the humeral 

 angles of the tegmina vinaceous. Apical portion of all the tibiae and 

 tarsi infuscated. Antennae at least basally testaceo-ferruginous. 



Length of body, 9 , l6 mm., of pronotum, 4 mm., of tegmina, 15 

 mm., of hind femora, 20 mm., of ovipositor, 10.5 mm. 



Habitat. — Chapada, Brazil (H. H. Smith). There are three addi- 

 tional female specimens at hand. These are also from the same lo- 

 cality. The type is in the Carnegie Museum of Pittsburgh.

The representatives of Aniarella are recognizable by the absence of 

 the spine from the anterior coxae and by the presence of nurherous 

 parallel transverse veins on the tegmina. Three species have already 

 been characterized, while a fourth is now added. They may be 

 recognized by the few brief characters as given in the subjoined 



Synopsis of the Species of Aniarella. 

 A. Mediastin vein of the costal field of the elytra subobsolete or entirely absent. 

 h. Deflexed lobes of the pronotum roundly or obtusely inserted. 



c. Size larger [c?, 20 mm., tegmina, 36 mm.]. Mediastin vein wanting. 



lypica Brunner. 

 cc. Size smaller [cf , 16 mm., tegmina, 26 mm.]. Mediastin vein present, 



but very short minor sp. nov. 



bb. Deflexed lobes of the pronotum acutely inserted, the angle marked by a 



narrow fuscous line proxima Brunner. 



AA. Mediastin vein of the costal field present, extending beyond its middle.

narrow fuscous line) punciidata Brunner. 



2. Aniarella minor sp. nov. 



As indicated by the synoptic key the present insect is most closely 

 related to the species typica, from which it differs in having the pos- 

 terior border of the tegmina minutely punctulate with fuscous, which 

 results from the veinlets being widely pallid over a fuscous back- 

 ground. 



General color pale green, the legs, head, pronotum, and bod}' tes-
