188 OKTHOPTERA. 



Elytrorum macula ut in ilia specie sat minuta, fusca, anterius linea callosa alba ; area analis coriacea, 

 maculis et margine postico hyalinis. Alse omnino flavo-fasciatae. Femora anteriora quam in reliquis 

 speciebus paulo latiora, latere interne- macula nigra maxima longiore quam alta, sulcum unguicularem 

 includente, ilium retro leviter superante. 



J . Elytra hyalina ; campo marginali et vitta discoidali ad venam principalem viridi-coriacea. Alae totae 

 hyalinee, fasciculis flavis nullis, apice leviter virescentibus. 



Var. c? . Elytri stigma partim hyalinum, inter maculam fuscam et albidam linea hyalina. 



$ . Long. 85 ; pronot. 36, elytr. 51*5, latit. elytr. 22, camp. marg. 8 millim. 



<3 . Long. 70 ; pronot. 25, elytr. 50, latit. elytr. 13, camp. marg. 3*75 millim. 



Hab. Guiana, Cayenne (Prudhomme, Mus. Genavense : 3 $ , 3 8 ). 

 Easy to distinguish by the very large macula on the anterior femora.] 



[PARASTAGMATOPTERA, Sauss. 

 Parastagmatoptera, Saussure, Mem. Mex., Mantid. p. 83 (1871); Stal, Syst. Mant. p. 68. 



A genus composed of smaller species than Stagmatoptera ; with the head not so 

 regularly triangular, somewhat less high, the prothorax shorter, and the elytra without 

 a coloured ocellus. In the males the elytra are hyaline, with the costal field more or 

 less green, and the antennae are distinctly serrulated. 



A small larva from Costa Rica perhaps belongs to this genus, the known species of 

 which are all South-American.
