Hab. Mexico, Cordova (Mus. Genavense ; H'6ge\ Misantla in Vera Cruz (F. D. G,). 



G. mutica may be a variety of G. bivittata with brown wings not tessellated with 

 pale lines. 



12. Gongrocnemis azteca, sp. n. 



Statura media. Flavo-testacea, valde fusco-irrorata. Antennae annulatae. Caput pallidum ; fronte, verticis 

 pictura vittaque postoculari fuscis. Pronotum dense granulosum, margine antico minute tuberculato, 

 canthis dorsalibus explicatis ; disco vel lineis 2 irregularibus longitudinalibus fuscis notato ; margine 

 postico truncato, fusco-maculoso. Lobi laterales superne plus minus fusco-marginati et obsolete maculosi. 

 Elytra grisea, viresceutia, fusco-maculosa, venis elevatis, in areolis magnis densissime punctato-reticulata. 

 Alae infumatae. Pedes valde fusco-marmorati. Tibiae intermediae supra mutica?. Femora antica siibtus 

 spinis 3, postica 6-7 armata ; spinae omnes flavidae, apice nigro. 



5 . Ovipositor arcuatus, margine supero tamen modice arcuato, dimidia parte apieali nigra. 



cJ . Segmentum anale transversum, margine medio late impresso. Lamina supra-analis late rotundato-trigonalis. 

 Cerci crassi, teretes, apice curvato, unguiculato. Lamina infra-genitalis elongata, trigonali-ineisa ; stylis 

 modice longis, obtusis munita. 

 Yar. a. Statura major. Frons pallida. Pronotum in lateribus verruculosum, supra obsoletius granulatum ; 

 metazona vix rugulosa. Elytra griseo-flavicantia, parce fusco-maculosa. Alae campo antico fulvescente, 

 venulis transversis obsolete pallide fasciatis. Femora antica et intermedia subtus spinis 4. Lamina 

 supra-analis impressa. — b. Alae in parte anteriore leviter pallido-maculatae. Tibiae intermediae spina 

 unica instructae. 



$ . Long. corp. 32 ; pronot. 8"1 ; elytr. 34-5 ; femor. post. 21 ; ovipos. 17 millim. 



cJ . Long. corp. 18 ; pronot. 6 ; elytr. 25-5 ; femor. post. 17 millim. 



Hab. Mexico, Cordova in Vera Cruz (Edge, Saussure). 



This species closely resembles G. munda, Brunn., but it is smaller and has the 

 intermediate tibiae unarmed above. 



The pale maculae of the elytra are variable in form, and when they are obliterated 

 G. azteca might easily be confounded with G. mutica, Brunn.
