whitish interocular bands, of which the dorsal is the wider, 

 separated by a dark brown band of intermediate width and 

 with the whitish bands margined with a broad suffusion of 

 brown dorsad and a darker narrow margin of brown ventrad. 

 The styles are also much more elongate, with internal portions 

 decidedly more produced than external portions and narrow 

 interval between the bases of the styles apparently unspecial- 

 ized. 



Type. $ ; Gatun, Canal Zone, Panama. July 8, 1920. (M. 

 Hebard.) [Hebard Collection, Type No. 763.] 



Size medium for the small species of the genus, form depressed, sur- 

 face glabrous. Head with occiput largely exposed. Interocular space 

 about one and one-third times the occipital ocular width, slightly over 

 three-quarters the width between the antennal sockets. Maxillary palpi 

 with fifth joint enlarged and elongate, slightly shorter than third joint, 

 fourth joint three-fifths as long as third. 



Pronotum transverse, subelliptical, greatest width slightly cauded of 

 median point; cephalic margin distinctly though broadly convex, caudal 

 margin transverse, feebly convex; latero-cephalic angles distinctly more 

 broadly rounded than latero-caudal angles. Tegmina reaching nearly as 

 far caudad as cerci, strongly elongate lanceolate, much as in transludda; 

 costal and sutural margins evenly and feeblv convergent, straight from 

 proximal third to the sharply rounded apex; discoidal vein with (ten 

 to eleven appreciable) costal veins, which are almost straight, discoidal 

 sectors (eight) oblique. 4 



Subgenital plate small, brief lateral margins concave and nearly 

 transverse each side of the large styles, this emargination deeper and 

 broader dextrad than sinistrad ; interval between styles very small, tri- 

 angular and apparently unspecialized. Styles similar, elongate com- 

 pressed structures, much longer than in translncida, each with external 

 section heavy, vertical in transverse section, tapering to its apex which 

 rounds into the external margin of the internal section; that section 

 longer, delicate, horizontal in transverse section, with ventral surface 

 concave longitudinally, of equal width to near apex, there a narrowing 

 is caused by a convexity of the external margin, which results in the 

 immediate apex being narrowly though not sharply rounded. Arma- 

 ment of limbs, tarsi, pulvilli, arolia and tarsal claws as in the related 



species. 5 



4 We have not examined the wings or dorsal surface of the abdomen 

 in this delicate unique. To do so might have caused serious damage and 

 we feel that the species is readily recognizable without these parts being 

 described.
