ORIENTAL CICADIDJE. 13S 



Genus EMATHIA. 



Ematliia, Still, Hem. Afr. vol. iv. p. 8 (18G6); Atkins. J. A. S. Beng. vol. liii. p. 229 (1885). 



Body robust. Head, including outer margins of eyes, narrower than base of mesonotum ; ocelli 

 wider apart from eyes than from each other; front broad and prominent. Pronotum with the lateral 

 margins straight, but arapliated at the posterior angles. Tympanal coverings rndimentary, the tympana 

 practically exposed. Opercula small, not extending beyond l)asal segment of abdomen. Rostrum almost 

 reaching the posterior coxse. Tegmina with the basal cell not quite twice as broad as long ; the interior 

 ulnar area about equally broad at base and apex ; first and second apical areas equal in length ; apical 

 areas eight in number. Wings with six apical areas. 



This genus, closely allied to Tibicen, was founded bj' Stal for the reception of a single 

 species at present only known from a restricted area of Continental India.

S . Body above dull dark ochraceous. Head with the front margined anteriorly by two narrow black 

 striae ; ocelli narrowly margined with black ; eyes pale ochraceous. Pronotum with a central longitudinal 

 sulcation, bordered with a small fuscous spot on each side at anterior margin, and starting from a wide, 

 transverse, and somewhat raised base, on the centre of which is a fuscous spot; fissures narrowly fusoons; 

 lateral anterior and posterior margins much paler. Mesonotum with two short obconical central fuscous 

 spots, and a large sublateral and somewhat broken fascia of the same colour on each side. Abdomen with 

 the posterior segmental margins narrowly and obscurely paler. Body beneath concolorous ; centre of face, 

 metasternum, disk and apex of abdomen, fuscous. Legs concolorous; femora streaked with fuscous; 

 bases and apices of tibire, and apical joints of tarsi, also fuscous. 



Tegmina and wings pale hyaline ; tegmina with the costal membrane and basal half of venation 

 ochraceous, remainder fuscous; transverse veins at bases of second and third apical areas, apical 

 transverse vein to radial area, and apical vein to interior ulnar area, more or less infuscated, and with a 

 small subapical fuscous spot. Wings with the base of upper apical area and the apex of abdominal area 

 infuscated. 



Face with the base much elevated, distinctly longitudinally sulcated, and strongly transversely 

 striate. Rostrum about reaching posterior coxje, with its apex pitchy ; opercula slender, curved inwardly, 

 but widely separated at base and apex. 



Long. excl. tegm. ^ , 18 millim. Exp. tegra. 48 millim. 



Hab. — Continental India : Bombay (Stockh. Mus.) ; Khandala (coll. Dist.). 



A typical specimen, kindly forwarded by Dr. Aurivillius, has enabled me to discriminate 

 this genus, and to see that the species I had described as Tibicen aurengzebe was really the type 

 of the same. 



Genus CICADATEA.

Body robust. Head, including eyes, much narrower than base of mesonotum; ocelli wider apart 

 from eyes than from each other. Pronotum broader than long, the posterior angles of the lateral margins
