 semi-obsolete markings ; inner wings aborted in both sexes ; 

 males with vertex convex, face flat ; palae thin, plate-like, upper 

 margin parabolic ; front femur with a large stridular area ; 

 asymmetry and strigil dextral ; fifth tergite entire, sixth

 ritory. 



KEY TO SPECIES OF PALMACORIXA. 



a. Clavus devoid of lineations on a large area near inner basal angle; 

 pala of male with two short rows of pegs on the lower basal third 

 (fig. 215, ;') ; front femur of female trapezoidal, two-thirds as wide 

 as long. 1244. gillettii. 



<ta. Lineations of clavus covering the entire surface; pala with a single 

 irregular row of 24 — 33 pegs along the middle of the sides (fig. 

 19) ; front femur of female oblong, two and a half times as long 

 as wide. 1245. buenoi. 



1244 (1461). Palmacorixa gillettii Abbott, 1912, 337. 



Pale yellowish with brown markings; head pale yellow; pronotum 

 minutely rastrate, yellowish, paler at sides, with eight to ten narrow, 

 broken, confluent dark cross-lines, some of the hind ones joining the 

 marginal line; clavus with inner basal portion yellow, outer margin with 

 a diagonal stripe along the corial suture, the intervening area with nu- 

 merous, variable, irregular dark markings ; corium and membrane with 

 vermiculate and inosculate brown markings, usually arranged in two 

 rather indefinite longitudinal stripes; embolium yellow; legs and under 

 surface yellowish-white. Male pala as in fig. 215, j, strongly compressed, 

 lower edge straight, upper one parabolic, surface covered with fine de- 

 pressed spines; pegs in two rows, upper row with five or six, lower one 

 with nine or ten; tibia globular, one-fourth the length of pala; femur 

 oblong, as long as pala. Length, 6 mm. 



Described from Colorado. Recorded by Hussey from Three 

 Oaks, Mich. He states that superficially it bears a strong re- 

 semblance to Corixa verticalis Fieb. 



1245 (1462). Palmacorixa buenoi Abbott, 1913a, 113. 



Oblong, subparallel. Above dull yellow to smoky brown, much darker 

 than gillettii, the lineations fuscous-brown; pronotum with seven or 

 eight narrow, more or less broken dark cross-bars alternating with yel- 

 low ones ; claval lineations narrow, vermiculate, fused along the outer 

 margin to form an irregular dark line parallel to the suture; pale zig- 

 zag marks of corium in somewhat regular longitudinal rows; front of 

 head, embolium, legs and under surface pale straw-yellow. Pronotum 

 and clavus rastrate; corium finely punctate. Male palae cultrate, three 

 times as long as wide, the pegs in a very irregular row (pi. XII, fig. 

 19). Length, 4.5—6 mm. (Fig. 215, i).
