GLAPHYROSOMA, Brunn. 

 Glaphyrosoma, Brunner v. Wattenwyl, Monogr. der Stenopelm. und Gryllacr. p. 39 (1888). 



This genus has been separated from Pherterus on account of the anterior tibiae 

 bearing no spines on their superior face ; but this character is not general, as G. aztecum 

 bears one spine, although it belongs by all its other characters to Glaphyrosoma. 



Generi Phertero habitu simillimum. Lobi laterales pronoti margine infero recto vel in medio subsinuato ; 

 angulo antico rotundato. Tibiae anticse supra inermes vel spina armatae. Tibiae posticae subtus inermes ; 

 eorum calcaria 2 supera utrinque aequilonga. Calearia supera bina ab intermediis aeque distantia. Lobi 

 mesosternales trigonales, haud acute producti. Lamina supra-analis : $ transversa, in medio divisa. 



$ $ . Lamina infra-genitalis trigonalis. Ovipositor falcatus, valde compressus, minus longus, acutus. 



c? d 1 . Ulfcimum segmentum dorsale (9 m ) grande, utrinque sinuatum, margine postico in medio producto, vel 

 inciso. Lamina supra-analis transversa, in medio infra ilium abscondita, tantum in latera supra cercos 

 conspicua. Lamina infra-genitalis convexa, quam lata brevior, apice biimpressa, stylos 2 brevissimos 

 obtusos gerens. Appendices anales laterales juxta cercos longi, styliformes, deplanati. Claustrum apicis 

 abdominis illis marium generis Pherteri haud dissimilis, sed potius excavatnm quam angulum recedentem 

 formans ; ejus lamella supera minuta, anguste acute triangularis, compressa, sulcata, utrinque carinata ; 

 apex sulcato-spiniformis, incisuram ultimi segmenti dorsalis leviter superans ; ejus pars infera elongata, 

 subperpendicularis, crassa, apice rotundata, supra subexcavata, basi aream obsoletam minutam puncto 

 elongato impresso notatam obferens.
