DiospoLis Westwood. 



I have examined the two female sjDecimens of Cicada elongata Fahr., 

 one of them without a head, in the Banks collection in the British 

 Museum, upon which Westwood founded this genus, and they are 

 SA'nonymous with Philadelphia pandani Kirkaldy. On the right 

 tegmen of one specimen and the left tegmen of the other there is an 

 aberration of the neuration, forming a small cell at the base of the 

 fourth median sector ; this has been figured by Westwood in both 

 tegmina. The head and eyes are not Hgui-ed wide enough. 



D. annetti, sp. n. 



Quite typical in structure, t'e face heinjjf slightly broader, especially the 

 apical portii)n ; wiiijis one-third the length of the tegmina. 



Bright vidlow over clypeus between the carinae, face, vertex, middle of 

 pronotuui, and mesonotum ; a broad mark down abdominal dorsum, over the 

 lateral portions of abdominal tergites, and hind margin of abdominal sternites ; 

 lighter yellow over the antennae, lateral portions of pronotum, and legs ; dark 

 brown over rostrum, lateral portions of clypeus, genae, eyes, medio-lateral 

 marks on pronotum, and lateral portions of mesonotum ; black on basal portion 

 of abdominal sternites, pregenital plates, and two broad medio-lateral bands 

 down dorsum with a few small yellow spots in them. Tegmina light fuscous, 

 darker over radial cell ; seven dark spots in costal and subcostal apical cells ; 

 iubcosta and radius light brown or yellowish ; media and sectors, cubital and 

 claval veins brown ; wings slightly fuscous with brown veins. 



Anal segment ver\' short, anal style long, narrow ; pregenital plate about 

 as long as broad, in profile slightly concave, hind margin produced on lateral 

 fourth, truncate in middle half ; uenital styles abortive.
