the New World, but all the species of those genera that I 

 have been able to examine have the posterior metatarsus 

 spined beneath. 



1. S. antipoda, Kirby. 



Pehnatosilpha (?) antipoda, Kirby, Aon. Mag. Nat. 

 Hist., ser. 7, xii, p. 87 G (1903). 



To Kirby's description may be added : — 



Tegmina with outer margins incrassate and sinuate. Wings 

 squamiform, scarcely exceeding the metanotuni. Supra-anal lamina 

 with non-serrate margins, apex non-emarginate. Styles not lateral 

 in position. 



Length 25 mm. ; tegmina 7'5 mm. ; pronotum 8'9 mm. x 12 mm. 



Queensland (British Mus.,type ; Oxford Mus., co-type). 



Genus 12. Methana, Stal.

Characters. Antennae longer than body. Pronotum anteriorly 

 parabolic, almost covering vertex of head, posteriorly very obtusely 

 angled. Scutellum not exposed. Tegmina and wings fully de- 

 veloped, at least as long as the abdomen, generally longer. Supra- 

 anal lamina (,^) quadrate, margins not serrate, ( 9 ) triangular, apex 

 emarginate. Cerci long, acuminate. Femora heavily spined. Pos- 

 terior metatarsus about equal in length to remaining joints, biseri- 

 ately spined beneath, its pulvillus apical ; remaining joints of tarsus 

 with large pulvilli, not spined beneath. 



Type of the genus : M. marginalis, Sau.ss.
