hXll.—Rhjnchotal Notes.— XXKYI. By W. L. Distant. 



Fam. Cicadidae. 



There are a few unique types described by Walker in tlie 

 British Museum, which have no locality and are female 

 specimens. Their generic identification is a matter of doubt 

 and difficulty, and the following notes have reference to same. 

 I also append the descriptions of some species from various 

 habitats. 



Parana ? hi'rundo. 



Cicada hirundo, Walk. List Horn. I. p. 152 (1850). 



This unlocalized type is a female specimen, not '' Mas " as 

 stated by Walker, and apparently belongs to tlie genus 

 Purana. 



Parana ? conifacies. 



Cicada conifacies, Walk, List Horn., Siippl. p. 35 (1858). 

 Dimduhia conifacies, StSl, Of v. Vet.-Ak. Forh. 1862, p. 481. 



This species is only represented by a single unlocalized 

 female specimen. It is apparently a species of Purana. 



Dtceropi/ga? nodosa. 



Cicada nodosa, Walk. List Horn. i. p. 162 (1850), 



A single unlocalized female specimen which I Iiave 

 doubtfully referred to this genus, the principal characters of 

 which are found in the male, viz., the opercula and the 

 structure of the anal abdominal seg-tnent. 



Diceropyga'^ acutipennis. 



Cicada acutipennis, Walk. Ins. Sauiid., Ilom. p. 20 (1858). 



This species is also only represented by a single unlocalized 

 female specimen, and the remarks appended to the previous 

 species equally apply to this one. 



Terpnosi'a? stipaia. 



Cicada sti^ata. Walk. List Ilora. i. p. 155 (1850). 



Only represented by a single unlocalized female specimen, 

 which seems clearly to belong to this genus. Should this 

 species be proved ultimately to belong to Terpnosia its 

 specific name must be altered, as it is already used in tlie 

 genus.
