The species of this genus, all of which are green, are tropical Ameri- 

 can in their distribution. Six have been recognized according to 

 Kirby's Synonymic Catalogue. Another is now added. They may 

 be separated by the accompanying synoptic table. 



Synopsis of the Species of Digphanes.^ 

 A. Genicular lobes of the anterior femora obtuse; those on the middle femora 

 internally armed with a spine. Middle tibiae spined above. 

 b. Humeral vein on the distal half diverging from the discoidal vein; branch 

 of hind radial arising before the middle. Wings roseate; styles of the 

 subgenital plate of the abdomen of male long. 

 c. Wings beautiful rose-colored. Ovipositor slender. [Mexico, Central, 



and South America] perspicillatus Fabricius. 



cc. Wings hyaline roseate. Ovipositor very broad. [Panama.] 



rosescens Saussure & Pictet. 

 bb. Humeral vein contiguous with the discoidal vein for a long distance, at the 

 apex suddenly defiexed. 

 c. Spines of the hind femora pale, their apex fuscous. 



d. Somewhat large. Metazona of the pronotum of male flattened. 

 Tegmina with the branch of the median starting beyond the 

 middle; tympanal field black-bordered. Wings whitish. [Bo- 

 livia] alrosignatus Brunner. 



dd. Smaller. Metazona of pronotum of male ascending. Tegmina 

 with the branch of the median arising before the middle; 

 tympanal field pale-bordered. Styles very short [Mexico]. 



abbreviatus Brunner. 

 cc. Spines of the hind femora black at their base and paler towards the 

 apex, or wholly black. 

 d. Hind femora with the spines pale towards the apex. Wings 



smoky. [Peru, Upper Amazons] ni gro-spinosus Brunner. 



dd. Hind femora with the spines entirely black. Wings pale yellow-

AA. Genicular lobes of all the femora each minutely spined, or those of the front 

 pair sometimes triangular. Intermediate tibiae unarmed above. Wings

98. Diophanes atrosignatus Brunner. 

 Diophanes atrosignatus Brunner, Monog. PseudophylL, p. 242 (1895); Saussure 

 & PiCTET, Biol. Cent.-Amer. Orth., I, p. 446 (1898). 



There are two specimens, male and female, of Diophanes before me, 

 which I am inclined to refer to Brunner's atrosignatus, although the}- 

 do not agree wuth the description in every respect.
