Genus Hyperphrona Brunner. 



Hyperphrona Brunner, Monog. Phaneropt., p. 315 (1878); lb., Addit. Monog. 

 Phaneropt., p. 165 (1891). 



This is one of the commoner genera of American katydids, but its 

 representatives seem to be confined to the tropical portions of South 

 America. A dozen or more species are already known. Another is 

 now added. The various representatives can be separated by the 

 table of Brunner's as printed in the later of the two publications re- 

 ferred to above. 



62. Hyperphrona abdominalis sp. nov. 



A rather large insect related to Brunner's striolata, from which it 

 difTers very notably in having the abdomen of both the male and 

 female very strongly tinted with bright carmine above, and along 

 the hind margins of all the segments, even well down their sides, 

 in the longer hind femora and tegmina of the male; and in having the 

 antennae ferruginous and annulated with fuscous throughout, instead 

 of being entirely fuscous. The terminal segments of the abdomen 

 of the male, together with the cerci are similar to those described for 

 this sex of striolata. General color yellowish green, the head, pro- 

 nolum, legs, and under side paler, almost dull white; antennae with 

 the two basal joints whitish and twice longitudinally streaked, and 

 the apex half-way margined with deep black; several of the following 

 joints, all of which are ferruginous, also longitudinally streaked with 

 black below. Eyes pale castaneous. Anterior and median tibiae 

 more or less tinged with ferruginous, the hind pair also to a limited 

 degree likewise tinted apicall}'. Tegmina with three dark blotches 

 along the ulnar vein where its principal branches are given off, the 

 dorsal margin and also the cells along some of the veins more or less 

 infuscated. Abdomen as described above, the last segment of ,the 

 male dorsally having the lateral acuminate lobes colored to their 

 tips. Ovipositor with the apex and corrugations or tooth-like rough- 

 cnings piceous.
