ORIENTAL CICADID.K. 119 



€ach other ; face oblique or obliquely convex. Pronotum narrower in front than behind, the lateral 

 margins non-ampliatcd and slightly oblique, the posterior lateral angles moderately reflexed and lobately 

 rounded. Anterior femora spined or dentate. Tympana more or less completely exposed ; opercula 

 small, usually obliquely convex, and not quite covering the cavities. Tegmina with their basal halves 

 usually more or less brilliantly coloured, sometimes opaque ; the costal margin, before the centre, suberect ; 

 the basal cell long ; apical areas eight in number, the first longer than the second. 



This genus is again confined to the Hmits of our fauuistic area, and hence all the described 

 species are here enumerated. They somewhat resemble in appearance several of the smaller 

 Sphingida).* 



1. Mogannia viridis. (Tab. XIV., figs. 8, a, h.) 



O-phahxi/s viridis, Siguoret, Ann. Soc. Ent. Fr. ser. 2, vol. v. p. 29-1 (1847); StiU, Ofv. Vet.-Ak. Forh. 1863, 



p. 483. 

 Cephaloxys rostratn, Walk. List Horn. i. p. 233, n. 4 (1850). 



Body above pale green, inclining to ochraceous, or, in some specimens, reddish-ochraceous. 



Tegmina and wings pale hyaline, the venation olivaceous or ochraceous (usually resembling the hue 

 of the body) ; tegmina slightly suffused with greenish or ochraceous at base, the costal membrane generally 

 reddish-ochraceous. 



The face is obliquely concave, the base being prominently and conically produced ; the rostrum about 

 reaches the intermediate coxje ; the opercula are slender and oblique ; the anterior femora beneath have 

 two small but distinct spines near apex. 



Long. excl. tegm. 3^ and 2 , 15 to 18 millim. Exp. tegm. 45 to 47 millim. 



Hab.— Continental India : Mungpoo in Bengal (coll. Dist.) : Naga Hills and Margherita in Assam 

 (Dohcrty— coll. Dist.). Burma: Momeit (Doherty— coll. Dist.). M-ilay Peninsula: Perak (Doherty— coll. 

 Dist.). Malayan Archipelago, Java (coll. Sign, and Brit. Mus.). 



Of eleven specimens of this species now in my collection, only one belongs to the 

 female sex. 



2. Mogannia fulva. (Tab. XIV., figs. 9, a, li.) 



Ceplialoxysfuha, Walker, Joiun. Liun. Soc. Zool. vol. x. p. 94, n. 29 (1867). 



Closely allied to M. viridis, Sign., but differing by the front of the head, which is much less produced 

 tlian in that species ; the face is also wider, more compressed, and much less obliquely concave than in 

 .1/. viridis. The opercula are more slender and wider apart. 



The colour of the specimen before me and of that described by Walker is ochraceous, but probably 

 fresh specimens are of a greenish hue. 



Long. excl. tegm. <? , IG millim. Exp. tegm. 42 millim. 



Hab.— Malayan Arciiipelago, New Guinea icdU. Dist. ; Wallace— Brit. Mus.). 



3. Mogannia obliqua. (Tab. XIV., figs. 10, a, /-.) 



Mogannia obliqua, Walker, List Hem. Suppl. p. 39 (1858) ; Atkins. J. A. S. Beng. vol. liii. p. 232, n. 87(1885) ; 

 Dist. Ann. Mus. Civ. Genoa, ser. 2a, vol. vi. p. 455, n. 8 (1888). 



5 . Head and pronotum above pale greenish or greenish-ochraeeous ; head with the apex of front and 

 the basal area blackish. Pronotum with a central triangular blackish fascia. Mosonotum with a broad 



- It was evidently species of thia genus that were described in the late Dr. Stoliczka's collection as " might at a glance 

 he mistaken for moths." — (V. Ball, ' Jungle Life in India,' p. 888).
