54 ORIENTAL CICADIDM. 



I have now examined a moderately large series of specimens belonging to this species, 

 and have found no variation in markings or coloration.

3- . Body above pale castaneous. Head with the area of the ocelli black. Pronotum with the lateral 

 and posterior margins, and a very narrow anterior margin, ochraceous ; the last is inwardly margined with 

 two small transverse linear black spots, and the posterior margin has also a very narrow discal inner 

 border of the same colom-. Mesonotum with a large central obconical spot on anterior margin, with a very 

 indistinct central line, and with the lateral borders black, outwardly margined with ochraceous ; five 

 indistinct black basal spots, three within the anterior angles of the cruciform elevation, and one on each 

 side of the same. Abdomen rather darker in colour, with the segmental sutures pitchy. Underside of the 

 body concolorous ; opercula dull ochraceous. 



Tegmina and wings pale hyaline ; tegmma with the costal membi-ane and claval area dull ochraceous ; 

 wings with the base narrowly of the same colour. 



The body is very elongated ; the head, including eyes, a little narrower than base of pronotum ; the 

 face is prominently convex, faintly longitudinally sulcated, and transversely striated ; the rostrum reaches 

 the middle of the posterior coxae ; the opercula are very long, reaching the penultimate abdominal segment ; 

 they are suddenly narrowed on first abdominal segment, and then gi'adually widened and rounded on each 

 side, the maximum width being at junction of second and third abdominal segments, from whence they 

 are gradually narrowed to apex, which is obtusely rounded. 



Long. excl. tegm. 53 millim. Exp. tegm. 124 millim.

As this is a somewhat variable species, the original description is given : — 



" Male and Female. Ferruginous-tawny. Head with two interrupted black bands. Prothorax with 

 eight irregular black stripes ; the middle pair curved and dilated hindward. Mesothorax with a black line, 

 and with four broader black stripes, which are more or less excavated ; the inner pair shorter than the 

 outer pair, and joining the line ; the outer pan- joining two black hind spots. Abdomen with whitish 

 tomentum on each side towards the base. Wings with a slight testaceous tinge, ferruginous-tawny at the 

 base ; veins tawny, partly black. Fore wings with a brown streak at tip of each of the marginal veins ; 

 transverse veins clouded with brown ; first transverse vein longer and more oblique than the second, from 

 which it is parted by more than twice its length. Male. — Opercula tawny, about two-thirds of the length 

 of the abdomen, much acuminated towards the tips." 



Long. excl. tegm. <? , 40 to 45 millim. Exp. tegm. 106 to 130 millim.
