opercula blackish. Tegmina hyaline, the bases of apical areas 

 except the 6th infuscated ; a row of well-defined hind-marginal 

 neural spots. Wings clear hyaline. Clavus of tegmina and 

 wings greenish-grey.

Type from Mt. Murud 6,500 feet, Sarawak, 14th Nov'e.nber 

 \922, coll. Dr. E. Mjoberg. Deposited in British Museum. 



Three cT from the same locality in the Sarawak Museum. 



A curious feature about this series of four specimens is the 

 variation in the neuration of the tegmina. The base of the 

 4th apical area on the right tegmen in three specimens is 

 closed by an additional infuscated nervule ; in one of these 

 three the left tegmen is similarly abnormal. The base of the 

 1st apical area is crossed by one additional infuscated nervule 

 in both tegmina in one specimen, by two in another, by tvvo 

 on the left tegmen and one of the right in a third, and by two 

 on the left tegmen alone in the fourth specimen. 



14. RlHANA PONTIANAKA Dist. 



1 cf from Mt. Murud 6500 feet. 

 A common species in Malaysia. 



15. Platypleura kaempferi fuscangulis Butl. 

 1 cf from Mt. Murud 6500 feet. 



A rare form confined to Borneo. The typical form was 

 described from Japan. Other subspecies occur in Annam 

 {annamensis Moulton) Malay Peninsula and Sumatra iridle- 

 yana Distant). 



16. Nelcyndana tener Stal. 



1 cT, 1 9 . both from Tutau River in the West Kalabit- 

 country . 



This is the smallest Cicada known in Borneo ; it measures 

 only 20—25 mm. across the tegmina, while the largest Bornean 

 species, Pomponia merula, measures about 200 mm., or 

 nearly 8 inches across the tegmina when set. 



Prof. C. F. Baker took 2 (f and a 9 of A^. tener at Sandakan 

 in British North Borneo. These three together with Dr. 

 Mjoberg's pair from Sarawak are the only specimens knowns 

 from Borneo. Prior to their capture the species was only 

 known from the Philippines.
