94 ORIENTAL CICADID^. 



Body robust and moderately long. Head broad with the front only moderately produced, including 

 eyes about as broad as the pronotum at its posterior margin ; ocelli about twice the distance from eyes as 

 from each other ; face moderately convex and tumid. Pronotum with the lateral margins moderately 

 ampliated, but neither toothed nor spiued. Anterior femora distinctly and moderately spined. Metasternum 

 not or very slightly elevated, but not provided with a posterior process as in Gryptoiympana. Tympana 

 covered ; opercula of variable length, generally short, but sometimes about two-thirds the length of the 

 abdomen, their apices broadly convex. Tegmina with the basal cell generally longer than broad ; apical 

 areas eight, interior ulnar area slightly widened at apex. 



This genus has an almost world-wide distribution. In America it is well represented in 

 both the Nearctic and Neotropical regions ; in the warmest parts of Europe it is not uncommon, 

 and its name frequently forms the theme for song among the classical poets of antiquity ; the 

 Ethiopian region possesses few species of Cicada ; but in Asia it again becomes a somewhat 

 dominant genus, and it is also found in Australia. I have described a fine species from the 

 Fiji Islands,* and we may probably conclude that it is not generally absent from Polynesia. 



A. Tegmina spotted. 



a. Opercula extending to two-thirds or half the length of the abdomen. 



b. Abdomen ornamented tvith longitudinal series of whitish pilose spots.

<y . Head black ; the eyes, apex and base of front, and a triangular spot on anterior margin of vertex 

 greenish-ochraceous. Pronotum castaneous ; the anterior, posterior and lateral margins, a narrow central 

 longitudinal fascia, and two small basal spots ochraceous ; these ochraceous margins and spots more or 

 less edged with black, the posterior margin crossed by three black bands — one central and one near each 

 lateral angle. Mesonotum black, with two broken linear ochraceous obconical basal spots, the lateral 

 margins and the basal cruciform elevation — excluding centre and apices — also ochraceous. Abdomen 

 black, with two slightly oblique white macular fasciae on each lateral area ; outer margins of the tympanal 

 coverings ochraceous. Body beneath, legs and opercula dull ochraceous, the sternum greyishly pilose ; 

 the lateral striations to face, the outer margins of coxae, inner margins of anterior and intermediate femora, 

 and the extreme apices of tibiae and tarsi black. 



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

 greenish, the transverse veins at the bases of the second and third apical areas broadly infuscated, and 

 those at the bases of the fifth and seventh areas narrowly infuscated ; the bases of the wings narrowly 

 pale greenish. 



The opercula are long, — about extending to two-thhds the length of the abdomen, — overlapping 

 internally, their outer margins moderately concave, their inner margins slightly convex, their apices 

 angularly rounded. 



Long. excl. tegm. <? , 38 millim. Exp. tegm. 105 to 110 millim.

Besides the bright and peculiar markings of this species, the unusual length of the 

 opercula affords a very distinctive character for specific differentiation.

 whose kindness I am indebted for the Cicadidce thus collected.
