ORIENTAL CICADIDJE. 57 



and one somewhat broken occupying; each lateral area ; abdomen above blackish,* the tympanal coverings 

 ochraceous. Head beneath, sternum, legs, and opercula ochraceous ; apices of anterior femora, the apices 

 of the tibife and tarsi, the transverse striations and longitudinal sulcation to face, and the margins of the 

 opercula black ; abdomen beneath castaneous, the apex pitchy. 



Tegmina and wings pale hyaline, the venation brownish ; tegmina with the costal membrane 

 brownish-ochraceous, the transverse veins at the bases of the second and third apical areas infuscated. 



The opercula are short, narrowed and angulated at apices, and reach the third abdominal segment. 



Long. excl. tegm. S , 30 millim. Exp. tegm. 82 millim. 



Hab. — CoREA (Belchert — Brit. Mus.). Japan (Fryer — coll. Dist.); Yokohama (Bruss. Mas.) ; Tokio 

 (Lewis — coll. Dist.) ; Southern Isld. (Leech — coll. Dist.). 



This appears to be a somewhat abundant species in Japan ; each of the collections made 

 by Messrs. Lewis, Prj^er, and Leech contained it, and in fair series. 



26. Cosmopsaltria microdon. (Tab. IV., fig. IG, a, h.) 



Dumluhiii microdon, Walker, List Horn. i. p. 55, n. 15 (1850) ; Atkins. J. A. S. Beng. vol. liii. p. 224, u. 40 (1885). 



Closely allied to C. opalifera, Walk., but larger; the opercula are much longer, and extend to the 

 penultimate segment of the abdomen ; they are also less concavely sinuate and more gradually narrowed 

 towards apex. The body is relatively much more robust. 



Long. excl. tegm. 3' , 30 millim. Exp. tegm. 90 millim. 



Hab. — Continental India: "North India," sic (Wallich — Brit. Mus.) ; Sikkim (coll. Dist.). 



27. Cosmopsaltria nicomache. (Tab. IV., fig. 12, a, b.) 



Dunditbia )irv>w((c/«, Walker, List Horn. i. p. G7, n.30 (1850); Atkins. J. A. S. Beng. vol. liii. p. 224, n. 44 (1885). 

 Cicada delineata, Walk. Ins. Saund., Horn. p. 17 (1858). 



As a female is here figm'ed, Walker's description of that sex is also given as follows : — 



" Black, testaceous beneath. Head testaceous about the eyes, and with two irregular testaceous 

 stripes. Front testaceous, with transverse black streaks. Frothorax with six various black stripes ; sutures 

 partly black ; margin testaceous, with three black spots on each side. Mesothorax with six irregular 

 testaceous stripes, and with a testaceous spot and a testaceous dot on each side in fi-ont between the 

 intermediate and exterior pair of stripes. Abdomen with a testaceous band on the hind border of each 

 segment ; under side mostly testaceous. Legs testaceous ; femora and tibiae with black stripes. TVings 

 vitreous; veins black, testaceous towards the base; first transverse vein upright, slightly curved, parted 

 by more than thrice its length from the second, which is slightly oblique; third and fourth oblique." 



S . Male with the opercula ochraceous, broad and long, their outer margins parallel with the lateral 

 margins of the abdomen, their inner margins straight, parallel and contiguous for a short distance, and 

 then griidually and convexly oblique to apices, which are broad, rounded, and extend to the upper margin 

 of the penultimate segment of the abdomen. 



Long. excl. tegm. S , 25 millim. Exp. tegm. 78 to 80 millim. 



Hab. — Continental India : North India, sic (Warwick — Brit. Mus.) ; Sikkim (Calc. Mua. & coll. Dist.); 

 Upper Assam, Margherita (Doherty — coll. Dist.) ; Naga Hills (coll. Dist.). 



This ajipcars to be a somewhat abundant species in the hilly region to which it is 

 apparently confined. 



* By some mischance tlie figiiro in printing; has failed to maintain its dark coloration. 



t This insect was evidently discovered and captured during the surveying voyage of II.M.S. ' Somorang,' commanded by 

 Capt. Sir Kdwd. Belcher, -nith Dr. A. Adams on hoai-d as Naturalist.
