84 ORIENTAL CICADID.E. 



short, or in other species nearly as long as the abdomen, and in shape either convex, rectangular or more 

 or less acutely angulated. Tegmina with the basal cell longer, but not twice as long as broad. 



The geographical distribution of this genus is comprised by the hmits of the fauna 

 treated in this monograph which thus includes all the recorded species. 



CnjptoUjmpana is a very distinct genus in the Oriental Cicadidae, the large size of its 

 species and their usually sombre coloration at once attracting attention, while the metasternal 

 process is an unfailing generic characteristic. 



Its nearest ally is the American genus Fidiciim, in which Walker placed the species he 

 described. 



a. Tegmina and 7vings infuscated. 



b. Opercula with their apices angulated.

(? . Body above black ; eyes, ocelli, a central longitudinal fascia to pronotum and posterior margin 

 of same dark ochraceous. Body beneath black ; opercula very dark castaneous, in some specimens with 

 their outer margins ochraceous. 



Tegmina and wings infuscated. Tegmina with a small basal black patch, the basal third and costal 

 area brownish-ochraceous, the outer margin and venation dark fuscous ; the transverse veins at the bases 

 of the second and third apical areas infuscated. Wings with about basal half brownish-ochraceous, inner 

 and outer margins broadly dark fuscous, and with a blackish basal patch. 



The opercula are nearly half as long as the abdomen, sinuate externally, slightly overlapping at their 

 inner basal margins, and inwardly concavely narrowed to apices, which are angulated. 



Long. excl. tegm. <? , 51 millim. Exp. tegm. 135 millim.

 chest ; face slightly convex, not at all prominent ; mouth black, reaching the middle-hips ; eyes not 

 prominent ; feelers black ; scutcheon of the fore-chest furrowed, having on each side a tawny spot, which 

 is different in size and shape from that of C. aquila ; sides very slightly convex in front and behind, 

 slightly notched in the middle part ; scutcheon of the middle-chest adorned with a dark tawny spot on each 

 side of the excavation, which is very slight ; abdomen obconical, a little longer than the chest, dark tawny
