54. Homorocoryphus nitidulus (Scopoli). 



Gryllus nilidulits Scopoli, Del. Flor. Faun. Insubr., I, p. 62, pi. 24B (1786); 

 Griffini, Boll. Mus. Zool. Anat. Comp. Torino, XI, no. 220, p. i (1896). 



For the very extended synonymy of this species see Kirby, Syn. Cat. 

 Orth., II, pp. 252-253. It was referred to Homorocoryphus by Karny, 

 the author of the genus, /. c, p. 44 (1907). 



Six males, one female, and three nymphs are at hand from Batanga 

 (F. H. Hope, Coll.) and two females from Lolodorf (A. I. Good, Coll.). 

 Another female which varies somewhat from the others in length of 

 wing and robustness of the hind tibiae, is doubtfully referred to this 

 species. It also is from Lolodorf, where it was taken by A. I. Good.
