 thirds the distance from the base, opaque; costal field occupying half the whole width, costal veins ver}- 

 distinct and disposed more transverse than longitudinal, stigma linear. Wings pellucid, fasciculate with 

 yellow, apex subangulate : ulnar vein undi\-ided. Anterior femora with four external spines.

Parastagmatoptera. Saussure, Mt-m. Hist, Xat. Mexique, Alant. .Amér. p. 83 (1871). 



Characters. — I'onn with long legmuia, h\-aline with the costal margin frequently opaque in 

 tlu- male, wings h\'aline in the same sex; female with moderatcl}- long opaque tegmina frequently 

 having scattered In aline areas and with barred or tessellate wings. Antennae, margins of tegmina and 

 wings and feet occasionally pilulose (in male of P. ciliata). X'ertex truncate, entirely or in the juxta- 

 ocidar portions more or less elevated above the eyes; ocelli of the male very large, approximate, placed 

 in a triangle, of the female smaller, disposed in an arcuate line; facial shield transverse, obtuse-angulate 

 dorsalh' with the angle truncate; eyes moderately prominent, convex; antennte of male serrate more or 

 less distinctly, subpectinate in scii'iconiis, of female setaceous, Pronotum distinctly shorter than the teg- 

 mina in both sexes, in the male slender, subcarinate, the margins hardlv (i'//';r/^^;/M/5) or distinctly («7/«/«) 

 denticulate for the entire length, tire supracoxal dilation slight; in the female more robust, not (_/?at'(;- 

 i^utlata) or but slightK' {sen icoruis) carinate, the margins distincth' denticulate for their entire length, the 

 su])racoxal dilation distinct, but not strongly developed. Tegmina longer than the abdomen in both 

 sexes, in the male elongate, vitreous, costal held coriaceous, dilated basally, the greatest width about 

 a fourth the total width of the tegmen, the principal veins colored in contrast to the coriaceous costal 

 field (serriconn's}. apex rounded subangulate; in the female broader than in the male and more ovate, 

 coriaceous, frecjuenlly \\\th a number of Inaline areas in the discoidal and suturai sections, costal field 

 about a third the total width of the tegmen, narrowing in the apical half, the apex bluntl}^ angulatCj 

 stigma present, but variable in shape. Wings barred or tessellate in the female. h\aline m the male, the 

 costal margin ti ('(luentlN- opaque in the female; discoidal vein ramose in the two sexes. Limbs slender. 

 Anterior cox;e rather sparsel\- denticidate or spinoso-granulato on the superior margin (these piligerous 

 in ciliata ), blackish area of internal face variable in position and size; anterior femora with four discoidal 

 spines, the external margin with four spines, internal margin with alternating large and small spines, 

 internal iace with \aiious types of coloration. Median and jiosterior limbs simple, without lobes. First
