 attenuata, margine infero-externo toto et ad apicem arcuato ; intus basi nigra, spinis marginis interni 

 alternatim nigris. Tarsi articulis 2°-5 m nigris ; antici tantum subtus nigri. 



J . Prothorax quam in specie laudata longior. Elytra et alee hyalina. Campus marginalis elytrorum 

 hyalinus, leviter virescens, haud opaous. Coxae anticae tantum apice nigrae. 



$ . Long. 37-5 ; pronot. 14, elytr. 29, latit. elytr. 9, camp. marg. 3 millim. 



cf . Long. 38 ; pronot. 14-75, elytr. 26, lat. elytr. 6*75, camp. marg. 1-3 millim.

Parastagmatoptera lobipes, Redt. P. Z. S. 1892, p. 206, t. 15. figg. 8a, 8 b ( <?). 

 Hab. . Antilles, St. Vincent. 



A well-marked species with strong hind femora. In the form of its pronotum and 

 of the small lobe of the hind femora it exactly resembles Oxyops icterica ; but its 

 serrulated antennae places it in the genus Parastagmatoptera.']

Stal described three other species allied to 0. rubicunda : 0. acutipennis, 0. media, 

 and 0. obtusa, all from South America. A small larva from Costa Rica perhaps belongs 

 to one of these species ; in any case it shows that either this genus or Parastag- 

 matoptera extends into Central America. This larva has the eyes less acute than 

 in 0. rubicunda, but less rounded than in 0. icterica. The anterior part of the 

 pronotum is elongate-ovoid, as in 0. rubicunda; but the pronotum itself is much 

 shorter. The anterior tibiae are unarmed at the base of their exterior margin, as in
