STAGMATOPTEEA. 185 



STAGMATOPTERA, Burm. 



Stagmatoptera, Burmeister, Handb. Ent. ii. p. 537 (1839) (pars) ; Saussure, Mem. Mex., Mantid. 

 p. 80; et auctores. 



In the following synopsis the species in brackets do not belong, so far as yet 

 known, to the Central-American fauna. 



Obs. — S. perpulchra, Westw. [Rev. Mantid. p. 36, t. 11. fig. 8 ( $ )], from Brazil, 

 belongs to a different type, which approaches Oxyops. A new genus is required for 

 its reception, which may be characterized as follows : — 



Genus Psetjdoxyops, n. — Oculi fere subacuminati. Elytra 5 obtusissima, a basi ad § longitudinem ampliata ; 

 campo marginali quam campus discoidalis latiore, venis costalibus distinctissimis, invicem remotis sub- 

 transversis. Alae flavo-fasciculatae, apice subangulato, subito viridi-coriaeese ; vena ulnari indivisa. 

 Femora antica extus spinis 4. 



S. pavonina, Burm., must also be excluded from Stagmatoptera. It is an African 

 species of the tribe Harpaginse, not yet identified with any certainty.
