Hab. Costa Rica, Cache (Sogers). 



This species is allied to G. tibialis, Brnnn. It differs from it in having stronger 

 femoral spines, and the anterior tibiae tuberculated at the inferior part of the margins 

 of the foramina, instead of below them. The middle of the pronotum is not tuberculate ; 

 the wings are not tessellated with pale-coloured bands, and they have rather regular 

 transverse venulse.

Gongrocnemis pallidespinosa, Brunn. v. W. Monogr. der Pseudophyll. p. 165, t. 7. fig. 75. 



Fulvescens, valde fusco-irrorata, subtilissime albido-punctata. Vertex et fasciae 2 laterales ab oculis emissae, 

 fusci. Pronotum granulatum, supra et lateraliter irregulariter in longitudinem fusco-fasciatum, margine 

 antico et postico fusco-maculato ; metazona rugulosa, canthis valde expressis, margine postico arcuato, 

 valde marginato. Elytra elevato-venosa, virescentia, fusco-marmorata, maculis rotundatis oblongis 

 impleta. Alae infuscatae, venulis transversis pallidis. Pedes valde fusco-marmorati. Femorum spinae 

 pallidse, in anterioribus subtus 4-5 ; in intermediis 4 ; in posticis 6-7. Tibiae anticae infra foramina 

 leviter tumescentes, praecipue in maribus ; intermediae supra bispinosae. 



2 . Ovipositor validus, rectus, dimidia parte apicali et tumore basali nigris. Lamina infra-genitalis late 

 trigonalis, apice incisa. 



S . Lamina supra-analis trapezina, angulis rotundatis. Cerci elongati, arcuati, apice unguiculati (sinistro 

 basi compresso). Lamina infra-genitalis plana, incisa ; stylis elongatis, rectis. 



Var. a. Corpus irregulariter marmoratum, vittis capitis et pronoti minus distinctis. Frons viridis, fastigio 

 fusco. Margo posterior pronoti minus arcuatus, canthis metazonae minus expressis. Elytra testacea vel 

 fusco-punctata. Alarum lineae pallidse irregulares. Ovipositor basi tumore haud nigra. — b. Frons 

 virescens, utrinque linea pallida. Caput obscurum, vitta infra oculos pallida. — (Mirandilla.) 



$ . Long. corp. 35 ; pronot. 8*5 ; elytr. 35 ; femor. post. 30 ; ovipos. 22-5 millim. 



cf . Long. corp. 38 ; pronot. 10 ; elytr. 36 ; femor. post. 25 millim. 



Hal. Mexico, Durango (coll. JBrunver), Presidio in Sinaloa (Forrer) ; Guatemala, 

 Balheu in Vera Paz, Mirandilla (Champion), Vera Paz (colls. Brunner &c). 



The specimens from Northern Mexico, including both sexes, are larger and have 

 darker elytra than the Guatemalan individuals here treated as a variety, but we are 

 unable to distinguish them by description.
