The type and allotype of this species are the only specimens we 

 have examined. 



Parastagmatoptera glauca new species. (Plate X, flgs. 8 and 9.) 



An interesting species related to P. theresopolitana and pellucido. 

 Giglio-Tos^i, agreeing with those species in the non-tessellate wings 

 and the siibpellucid, non-fenestrate wings. From both of these 

 species, however, glauca differs in its much smaller size, more weakly 

 denticulate lateral margins of the pronotum, the narrower marginal 

 field of the tegmina and impunctate stigma, and, in addition, from 

 theresopolitana in the absence of black from the wings and cephalic 

 coxae and in the unmarked bases of the larger internal spines of the 

 cephalic femora. 



Type. — 9 ; Colonia Hansa, State of Santa Catharina, Brazil. 

 [Hebard Collection, Type no. 221.] 



Size small , form somewhat more robust than usual in the same sex 

 in this genus. Head depressed trigonal in form, with the greatest 

 width one and one-half times as great as the greatest depth of the 

 same; occipital outline sinuato-truncate between the juxta-ocular 

 sulci, juxta-ocular section (laterad of the sulci) moderately arcuato- 

 bullate, sulci moderately impressed, straight, vertical for the greater 

 portion of their length; face hardly concave; ocelli small, distinct, 

 placed in a very much depressed triangle; facial scutellum strongly 

 transverse, the greatest depth contained about two and one-half 

 times in the greatest width, dorsal margin very broadly rounded 

 obtuse-angulate mesad and faintly emarginate laterad, dorso-lateral 

 angles nearly rectangulate, ventral margin shallowly arcuato- 

 emarginate, surface faintly excavate; eyes well rounded in outUne 

 when seen from the cephalic aspect, in basal outline subovoid- 

 p>Tiform, flattened caudad; antennae fihform, in length slightly 

 shorter than the pronotum. 



Pronotum moderately robust, greatest width of supra-coxal dila- 

 tion contained three and one-third times in the greatest length; 

 collar broad, margin regularly expanding from the strongly arcuate 

 cephalic margin; supra-coxal dilation hardly differentiated from 

 the collar, passing regularly by expansion from one to the other, 

 broadly rounded and as evenly narrowing caudad to the shaft, 

 the caudal half of which is subequal in width, caudal margin trun- 

 cate mesad, well rounded laterad, entire lateral margins closely 

 denticulate; median line on collar and cephalic section of shaft
