ORIENTAL CICADID.E. 89 



Tef^raina and winpis hyaline, the venation ochraceous and fuscous. Tegmina with the costal 

 membriino ochraceous, the postcostal area blackish ; the base, as far as extremity of basal cell (excluding 

 venation), irregularly blackish ; transverse veins at bases of second and third apical areas infuscated 

 (in the specimen figured the upper apical area is practically wanting), and a pale fuscous outer marginal 

 fascia. Wings with less than basal third (excluding venation) blackish. 



Opercula more than half the length of the body, overlapping at their basal margins, the outer 

 margins slightly concavely sinuate, the inner margins concavely and obliquely sinuate to apices, which 

 are subacutely angulated. 



Long. excl. tcgm. J , 36 to 43 millim. Exp. tcgm. 102 to 130 millim. 



Hab.— Continental India: " Uhutan Duars" * (Calc. Mus.). Malayan Archipelago: Java (coll. 

 Sign. ; Argent— Brit. Mus.) ; Kederi (von Hiigel— coll. Dist.) ; Borneo, Sandakan (Fryer— coll. Dist.) ; 

 Philippine Isles (Semper — Stockh. Mus.) ; Palawan (coll. Dist.) ; Timor (Wallace— Brit. Mus.). 



I have examined a typical specimen of C. vicina, Sign., which was kindly forwarded to 

 me by my late friend Dr. Signoret, and I found it impossible to separate it from the figure 

 of C. <inita given by the same author. The opercula of C vicina shown by another figure are 

 apparently not correctly pourtrayed, if the specimen forwarded to me as typical could be 

 relied on, which coming from its describer should surely be the case. Under these 

 circumstances I have felt no hesitation in placing C. vicina, Sign., as a synonym of C. acuta, 

 Sign. Dr. Signoret's figure of C. acuta is also much more brightly coloured than any specimen 

 that has come under my observation. 



11. Cryptotympana demissitia, u. sp. (Tab. XIII., fig. 11, a, h.) 



$ . Body above very dark castaneous, abdomen almost black ; eyes ochraceous ; pronotum with the 

 posterior and lateral margins paler ; mesonotum with six obscure obconical spots on anterior margin, the 

 two central plainest, and a curved fascia between anterior angles of the basal cruciform elevation black. 

 Body beneath dull, dark ochraceous ; sternum thickly clothed with ochraceous pile ; face, space between 

 face and eyes, the anterior tibiae and the rostrum blackish ; intermediate tibiae with the bases and apices 

 blackish. 



Tegmina and wings hyaline with a very slight fuscous tinge, the venation dark, dull ochraceous; 

 tegmina with the costal membrane ochraceous, the postcostal area blackish, the transverse veins at the 

 bases of the second and third apical areas infuscated ; the base as far as extremity of basal cell (excluding 

 venation) blackish. Wings with the base very narrowly blackish. 



Opercula very long, extending to the apical segment of the abdomen, slender, divergent, with 

 their apices subacute. 



Long. excl. tegm. ^ , 42 millim. Exp. tegm. 115 millim. 



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



The great length and peculiar structure of the opercula render this species very distinct.
