80 ORIENTAL CICADIDM. 



Mesonotum with two large obconical spots starting from centre of anterior margin and connected by a 

 central longitudinal fascia with the basal cruciform elevation, where it is broadened into a transverse fascia 

 between its anterior angles ; the central obconical spots are followed by a small spot and again by a long, 

 cm'ved, and posteriorly widened fascia, black ; two parallel linear black spots on disk of basal cruciform 

 elevation, and a black spot on each side of same. Abdomen greenish-ochraceous, much shaded with black, 

 the apical third and the tympanal coverings almost wholly black. Body beneath with the head, sternum 

 and legs greenish-ochraceous, the opercula and abdomen black ; the abdomen with a marginal ochraceous 

 fascia at apes of opercula ; transverse strife to face, a line between face and eyes, inner margins of eyes, 

 outer margins of prosternum, a central line to and the apex of, rostrum, spots to coxae and trochanters, 

 linear streaks to femora, and the apices of tibiiB, black. 



Tegmina and wings pale hyaline, the venation alternately ochraceous and fuscous ; tegmina with a 

 small ochraceous spot at inner angle of upper ulnar area ; the transverse veins at the bases of second, 

 third, fifth and seventh apical areas infuscated, and a marginal series of small fuscous spots placed near 

 the apices of the longitudinal veins to apical areas ; the costal membrane pale greenish. 



The opercula are moderately large, convex and overlapping at centre ; the rostrum extends beyond 

 the posterior coxae ; the face has no trace of a central longitudinal sulcation. 



Long. excl. tegm. <? , 26 millim. Exp. tegm. 88 millim. 



Hab. — Continental India (Brit. Mus.) : Eastern Himalaya Mts. (coll. Dist.) ; Sikkim (Calc. Mus.). 



According to the writer's present knowledge, this species seems quite confined to the 

 North-Eastern area of Continental India.

Cicada maculaticollis, Motschulsky, Bull. Soc. Nat. Mosc. xxxix. p. 185 (1866). 



Head, pronotum, and mesonotum greenish-ochraceous. Head with the transverse strise to front, the 

 area of the ocelli, a larger spot at inner margins of eyes, posterior margins of eyes, and a transverse linear 

 spot at anterior angles of vertex, black. Pronotum with two central linear fascia, sinuated and ampliated 

 anteriorly and posteriorly, a discal spot on each side, the furrows, two transverse spots on outer margin, 

 and the extreme lateral and posterior margins, black. Mesonotum with two central obconical spots, 

 followed by some irregular markings on anterior margin, a large spot on each side of disk, a small rounded 

 spot at anterior angles of basal cruciform elevation and two central lines on disk of same, black. Abdomen 

 greenish-ochraceous, the tympanal coverings and more than basal halves of segments, black. Body 

 beneath and legs greenish-ochraceous ; transverse strife to face, inner area of eyes, central line to and apex 

 of rostrum, femoral streaks, bases and apices of tibiae, outer and posterior margins of opercula, and basal 

 halves of abdominal segments, black. 



Tegmina and wings pale hyaline, veins ochraceous and fuscous. Tegmina with a small ochraceous 

 spot at inner angle of upper ulnar area ; the transverse veins at the bases of the second, third, fifth and 

 seventh apical areas infuscated, and a series of small fuscous marginal spots situate near the apices of the 

 longitudinal veins to aj^ical areas. 



The opercula are broad, convex and overlapping ; the face has a faint central longitudinal sulcation, 

 and the rostrum extends to the posterior coxfe. 



Var. a. — Differing from typical specimens by having the abdomen above ornamented by a transverse 

 fascia of white pile situate immediately behind the tympana and widened at the lateral margins ; the 

 abdomen beneath is also more or less thickly covered with white pilosity. The opercula in this variety 

 are also totally black. 



Var. b. — In this variety the ground colour is ochraceous, and not greenish-ochraceous ; the black 

 markings to the head, pronotum and mesonotum are also much larger and more or less confluent ; the
