Hah. Mexico, Ciudad in Durango 8100 feet (Forrer). 



Two males and one female. This species resembles T. prorsa, from Georgia, but 

 differs from it in the more angular front margin of the pronotum, wider vertex, more 

 prominent eyes, and stouter hind femora. 



7. Tettigidea nigra, sp. n. 



Vertex and crown strongly convex above, a little less angulate in front than in 

 T. tecta ; the mid-carina smaller, less prolonged backward, barely reaching the 

 level of the eyes. Facial costa narrowly sulcate, the upper part narrower, with 

 parallel sides. Pronotum tectiform, mid-carina prominent, subcristiform ; the 

 surface smooth, finely granulate, the transverse sulci impressed ; scapular area 

 wanting or very nearly so ; front margin rounded-angulate, advanced one-fourth 

 to one-third its width ; hind process abbreviated, not reaching the end of the 

 femora ; lateral lobes with the posterior sinus of usual size, sometimes a little 

 shallow. Elytra of usual size and form, with a subapical oblique pale bar. 

 Wings absent. 



Colour black, except the face below the eyes, the apex of the pronotum, and the apex 

 and venter of the abdomen ; tibiae and tarsi fasciated with fuscous. 



Total length, d , 8-5-9 : pronotum, d , 8-8*5 ; post, fern., d , 5-5-6*4 millim. 



Hah. Mexico, Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet 

 (H. H. Smith), 



Three males. In colour this species presents a notable exception (at least in the 

 types) to the general reddish-brown hue prevalent in the genus.

" Pallide grisea, fusco variegata ; femoribus fusco-fasciatis. Vertice oculo angustiore, antice obtuse parum 

 producto, medio carinato, a latere viso rotundato. Pronoto antice rotundato-subangulato, postice subulato 

 apicem femorum vix superante ; dorso sub-lsevi, rugis longitudinalibus fere indistinctis ; inter humeros 

 convexiusculo, carina media parum elevata pallide fuscoque notata ; carinis lateralibus prope marginem 

 anticum perspicuis, curvatis, retrorsum divergentibus. Elytris lsevibus, fuscis, extus pallidioribus, ante 

 apicem macula obliqua pallida notatis ; alis longe pone apicem pronoti extensis. Femoribus posticis 

 minute granulatis : articulo primo tarsorum posticorum pulvillis inferne subrotundatis j tertio parum 

 longiore.

" Chez cette espece le pronotum est presque prive des carenes longitudinales 

 irregulieres que Ton voit dans les autres especes du genre. Par sa taille elle pourrait 

 figurer entre T. polymorpha, Burm., et T. lateralis, Scudd."
