dian femora slightly larger than the cephalic and similarly armed; 

 tibiae similar in armament to the cephalic. Caudal femora reaching 

 nearly to the apex of the abdomen, the proximal portion (two-thirds) 

 considerably inflated and tapering to the slender distal fourth, genic- 

 ular lobes rounded, ventro-lateral margins with eight to ten spines 

 ranging from a mere tubercle proximad to large dentiform structures 

 distad; tibiae about equal to the femora in length, all margins regularly 

 ppined, those of the dorsal margins closer together and more numerous 

 than on the ventral face. 



General color russet, the limbs and venter more wood brown and 

 fawn color. Principal thoracic sutures, coxae, all femoral spines, later- 

 al and median areas of the subgenital plate of the male and the distal 

 half of the ovipositor marked with blackish. Tegmina with a weak 

 suffusion of apple green. T}^iiipanum of the male blackish. ■ 



Measurements. 



Length of body, 34.5 mm. 40 mm. 



Length of pronotum, 7 " 7.8 '' 



Length of tegmen, 26.3 " 3L2 " 



Length of caudal femur 18.5 " 21.5 " 



Length of ovipositor, 19 " 



A series of seventeen specimens, five males, twelve females, of this 

 species have been examined. The localities represented are: San 

 Jose, September, 1902, three males, six females; Monte Redondo, Janu- 

 ary, 1903, one male; Tarbaca, October and November, 1902, one male, 

 three females; Cizahar de Cartago, October, 1902, one female; Tablazo, 

 November, 1902, one female; Guatel, August, 1902, one female. 



This series exhibits considerable variation in size and a slight amount 

 in color, but in this regard chiefly in the strength of the greenish suf- 

 fusion of the tegmina. In a few specimens the tegmina are somewhat 

 tessellated by the infuscation of veins, but usually this is not pro- 

 nounced. The pronotum is in several specimens rather dark, while the 

 cingulate margin is light colored, producing a decided contrast. The 

 most striking variation, however, is in size, one male and several 

 females being considerably smaller than the types of their respective 

 sexes.
