268 Rev. F. D. Morice's Notes on Australian Saytflies. 



S. \V. Australia (Swan River, etc.). Type (a <$) at 

 Oxford. 



— All lobes of the mesonotum entirely testaceous, or rarely brown 

 (no part chalybeous) 10. 



10. Scutellum quite smooth and impunctate with no indication of 



a dividing line or furrow. Wings, at least towards their 

 apices, slightly infuscated klugii, Westw. 



S. W. Australia (Swan River). Type at Oxford. 



— Scutellum punctured, or bisected by a longitudinal line or a 

 shallow furrow. Wings glassy and quite clear. . . . 11. 



11. Scutellum with dense rugose punctures, bisected by a distinct 



though shallow longitudinal impression . . kirbii, Leach. 



Victoria. Type (a ^) in B.M., also one $. 



■ — Punctures of scutellum more or less remote 12. 



12. Scutellum with a very few hardly noticeable punctures, bi- 



sected longitudinally by a fine impressed line. 



brevitdrsis, n. n. 



The unique specimen in B.M. was referred by W. F. Kirby 

 to kirbii, but is evidently not that species. It differs 

 from all other forms by its extremely short tarsi, which 

 look only about half as long as the tibiae ! 



S. W. Australia (Swan River). Type in B.M. 



Scutellum moie largely and closely punctured than in brt vi- 

 ta r-sis, hut not coarsely and rugosely as in true kirbii. Hind 

 tarsi of normal length agitata, n. sp.* 



This also is a unique specimen. Its saw (PI. XIV, Fig. 3) 

 is more like that of dorsalis than those of the species to 

 which it seems more nearly allied. Towards its base, 

 however, which is not shown in the Figure, the teeth alter 

 their shape and become bent as in Iclugii, etc. (Possibly 

 this character is merely individual. More specimens are 

 needed to settle the point.) 



Victoria. Type in B.M. 



* Perga agnata, n. sp. 



§ P. kirbii, Leach, uotis paene omnibus scilicet statura, colore 

 lutescente, alis limpidis, etc. — simillima. 



Differt scutello sparsius punctato, lobis eiusdem apicalibus minus 

 productis, denique terebrae denticulis aliter formatis scilicet 

 hand uncinatis omnibus, sed plerisque (ut in /'• dorsali et affini) 

 lenissime tantum curvatis, immo paene rectis. 



; differl a /' kirbii J scutello multo sparsius punctato.
