HELIOEYCTBS. — GORYTES. 271 



Gambia district in West Africa. From West Africa also there is 

 in the collection of the British Museum one specimen of a third 

 species of this genus, possessing the characters as given by Smith, 

 and also the coxal spines. In the collection it stands as Para- 

 nvsson ahdominaJe, Gruerin, and answers well enough to Gueriu's 

 brief description so far as this goes. The genus Parani/sson was 

 indicated (scarcely diagnosed) by Guerin in his ' Iconographie du 

 Eegne Animal de G. Cuvier : lusectes,' p. 441; but the description 

 was so slight and incomplete that in my opinion Smith's name 

 for the genus must stand. I mav further note that Haudlirsch 

 (Sitzungsb. Akad. Wiss. Wieu, 1887, p. 282) unites Paranysson 

 with Nysson.
