NEW SPECIES OF CICADID^ FEOM SUMATEA. 



By J. C. MouLTON, B.Sc. 



The following species form part of a collection made in 

 Sumatra by Mr. H. C. Eobinson, Director of Museums, Feder- 

 ated Malay States, end Mr. C. Boden Kloss, Curator. The 

 descriptions were drawn up two years ago, and were embodied 

 in my report on the collection of Cicadas obtained by these two 

 naturalists on their expedition to Mount Korinchi, Sumatra. 

 As there appears to be no immediate prospect of publishing the 

 various reports on these collections, I have thought it advisable 

 to publish the following descriptions without further delaj'. In 

 doing so, I wish to acknowledge the kind help of my friend 

 Mr. W. L. Distant, who has been good enough to check my 

 descriptions and compare the specimens with the British 

 Museum collection, so that I hope their " noveljty " may be 

 regarded as undoubted. 



Purauoides, gen. nov. 



Differs from Purana in the absence of lateral tubercles on the 

 second and third ventral segments ; the rostrum just passes the 

 posterior coxge. The two genera, Purana and Maua, are very similar 

 to this genus, but differ in having two pairs of lateral tubercles. 

 One other genus [Lej^tojjsaltria) also has two pairs, anotiier (Tanna) 

 has one pair, and I have collected a specimen on Mount Kinabalu 

 in North Borneo, representing an undescribed genus, characterised 

 by the presence of three pairs of lateral tubercules. 



Head (including eyes) as wide as base of mesonotum and as long 

 as space between the eyes ; lateral margins of pronotum subangu- 

 late ; abdomen in the male considerably longer than space between 

 the apex of head and base of cruciform elevation, posterior portion 

 gradually attenuated. Opercula small, not reaching second ventral 

 segment. Tympanal coverings broader at base than long. 



Tegmi^a and wings hyaline. Fore femora spined. 



Type. — P. klossi, sp. n. 



Puranoides klossi, sp. nov. 



Male. — Head, pronotum, and mesonotum greenish-ochraceous ; 

 head with margins of front, space between the ocelli (and spot in 

 front of the middle ocellus) and two small spots between the ocelli
