This species is also represented in the collections before us 

 from Costa Pica. The coloration of the present specimen is 

 exactly as described, with great clarity, by Westwood. 



Length of body, 59; length of pronotum, 5.2; width of pro- 

 notum, 7.8; length of mesonotum, 6; length of tegmen, 34.4; 

 length of wing, 45.6; length of cephalic femur, 10.8; greatest 

 width of cephalic femur, 5.9; length of caudal femur, 13.5; 

 greatest width of caudal femur, 6 mm. 



Prisopus arladne new species (Plate XIV, figures 3 to 8 ) 



This interesting species agrees only with P. cephus Westwood 

 in having the radiate field of the wings unicolorous. The 

 numerous glossy yellowish tubercles, scattered over the proxi- 

 mal portions of the tegmina, afford a distinctive character. 

 Compared with the described male of cephus, this sex differs 

 further in having the head tuberculate but not spinose, the 

 tegmina with the tuberculations noted above, and with a lamellate, 

 acute-angulate production at the shoulders, and the five distal 

 tergites lobate laterad, this strongest on the seventh. 



The female differs in being larger and heavier, with projection 

 at tegminal shoulders reduced to a low rounded lamella, and 

 lateral lanicllatiou of tergites nnich stronger. 



'"And "Litt. occid. Americae se{)tcntrionalis." Tlie figured male from 

 Panama is here designated the single type.
