ORIENTAL CICADID^. 86 



" Length of the body 21 lines ; of the wings 57 lines." 



Hab.— Malayan Archipelago: Philippine Isles (Cuming — Brit. Mus.)- 



The tjiiical specimen in the British Museum is the only knowledge of this species 

 possessed by the writer. That specimen is here figured, and the original description 

 reproduced. 



bb. Opcrcula venj hiKj, their apices very broad and somewhat convex. 



3. Cryptotympana diomedea. (Tab. XI., fig. 3, a, b.)

3 . Body above dark castaneous ; head with the front, the area of the ocelli, and a spot behind eyes, 

 black. Pronotum with the furrows black and four small central basal spots of the same colour, situate 

 two near the anterior edge of the posterior margin, and the other two on its hinder edge. Mesonotum 

 with four obconical spots starting from anterior margin, the two outermost largest, between the two 

 central is a discal lanceolate spot, and a spot near each anterior angle of the basal cruciform elevation, 

 black. Abdomen almost black. Body beneath and legs pale castaneous, with a central blackish fascia 



to face. 



Tegmiua and wings palely infuscated, the venation pale castaneous ; tegmina with the costal 

 membrane and the basal cell castaneous, a small irregular basal blackish patch and the transverse veins 

 at the bases of the second and third apical areas darkly infuscated. 



The body is very robust ; the opercula reaching the apical segment of the abdomen do not overlap, 

 have their inner and outer margins almost parallel and their apices moderately convex, their inner and 

 apical margins are also clothed with pale long hairs. 



Long. excl. tegm. 3^ , 48 millim. Exp. tegm. 148 millim. 



Hab. — Malayan Archipelago : Sumatra (Forbes & Bock — coll. Dist.). 



I have now been able to describe and figure a male specimen of this species for the 

 first time, and also to fix its habitat, as Walker's description was only of an unlocalised 

 female form. 



aa. Tegmina only faintly infuscated. 



bbb. Opercula long, gradually narrowing to apices.

Cryptoti/iiipami epithesia. Distant, Ann. & Mag. Nat. Hist. ser. 6, vol. ii. p. 825 (1888). 



S . Allied to C. diomedea. Walk., from which it differs by its smaller size and more hyaline tegmina 

 and wings, but principally by the totally different structure of the opercula, which in the male of C. epithesia 

 are narrowed posteriorly and are obliquely wide apart at apices, which about reach the penultimate 

 segment of the abdomen. 



Long. excl. tegm. 3 , 44 millim. Exp. tegm. 134 millim. 



Hab. — Malayan Archipelago : Borneo (coll. Dist.). 



B. Tegmina and wings pair hyaline. Tegmina with basal third and costal area black or fuscous.

<? . Body above black ; eyes ochraceous ; ocelli luteous. Pronotum with some indistinct discal
