A New Species of True Katydid from Western Texas 

 (Orthoptera ; Tettigoniidae). 



By James A. G. Rehn and Morgan Hebard. 



Pterophylla excelsa new species. 



General appearance and form similar to P. camellifolia 

 {CyrtophyUus perspicillatus of authors) ; general form of pro- 

 notum similar to that species but resembling that of Paracyr- 

 tophyllus robustiis in the caudal margin of the disk, which is 

 subtruncate, and in the length of the same which is less than 

 the greatest width ; ventral margins of lateral lobes of 

 pronotum differ from all other North American species in 

 being moderately oblique, declivent cephalad. Subgenital 

 plate of males distinctive in form and reaching beyond the 

 tips of the tegmina, but apparently showing a development 

 of the type found in Paracyrtophyllus rohustus. Cerci of 

 male distinctive but showing nearest affinity to Lea flori- 

 densis. 



Type.—Ma\e; Moss Well, foot of PuUiam Bluff, Chisos 

 Mountains, Texas. September 5-8, 191 2. Elevation 470c- 

 5000 feet. (Rehn and Hebard.) [Hebard Collection.] 



Size and general form similar to camellifolia. Head larger and 

 broader than in that species, with fastigium of the vertex more de- 

 cidedly produced in a spine which projects distinctly beyond the 

 plane of the face ; face much flattened, with lateral margins distinctly 

 defined in weak ridges, these ridges subobsolete dorsad ; labrum dis- 

 tinctly broader than in carnellifolia. Pronotum similar to ca7nellifolia 

 in contour, transverse sulci and lateral canthi, but with length of disk 

 less than greatest (caudal) width and with caudal margin subtrun-
