260 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



Coloration. — cf. Head and pronotum burnt lake, with the 

 exception of the occiput and dorsum of the pronotum, which 

 have the medio-longitudinal stripe very deep burnt lake and the 

 remaining portions buff yellow. Eyes prussian brown varying 

 to cinnamon in different individuals. Tegmina infuscated, with 

 veins shamrock green, hyaline areas of tympanum iridescent; 

 wings with hyaline portion iridescent and with costal margin and 

 brief distal exposed (when at rest) portion rather strongly infus- 

 cated. Abdomen buff yellow considerably infuscated, with 

 broad median and lateral stripes of burnt lake, ccrci burnt lake. 

 Limbs tawny, washed with burnt lake. 



o . Head, lateral lobes of pronotum (below a very narrow 

 postocular stripe of burnt lake) and femora shamrock green 

 somewhat infuscated. The buff yellow lateral margins of the 

 burnt lake medio-longitudinal stripe of the occiput and dorsum 

 of the pronotum are decidedly broader than in the male, on the 

 pronotum extending over the dorsal portions of the lateral lobes. 

 Tegmina, including veins, infuscated; wings as in the male. 

 Abdomen colored much as in that sex. Ti])iae and ovipositor 

 hazel, weakly suffused with greenish. 



The Venezuelan females are the palest examples before us and 

 lack dark markings on the lateral lobes of the pronotum, 

 while the dark abdominal stripes are greath^ reduced in breadth. 



Specimens Examined: 9; 4 males and 5 females.
