12. Philopotamus flavidus Hag. Of this species, only 

 known from Corsica, there is a male. 



13. Hydropsyche instabilis Curt. Five females. 



14. Tinodes sp. One female. 



15. Rhyacophila obliterata Mac Lachl. Two females. 



Megaloptera. 

 Raphidia insularis Albarda. Two males and six females 

 are present; the species is only known from Corsica and 

 Sicily. 



Planipennia. 



The most interesting discovery from this order is Neur- 

 orthus fallax and Micromus gradatus. N a v a s in »Quelques 

 Névroptéres de Corse recueillis par M. G. Bénard« (Insecta, 

 Rennes, 1912, pag. 34) mentions also Theleproctophylla au- 

 stralis Fabr. and Creagris ægyptiacus Ramb., but I have not 

 seen the two species from the island. 



1. Palpares libelluloides Linn. Two specimens, females, 



captured at Ajaccio. 



2. Macronemurus appendiciilatus Latr. One female. 



3. Ascalaphus corsicus Ramb. Three females. 



4. Osmylus maculatus Fabr. A long series of fine spe- 



cimens. 



5. Neurorthus fallax Ramb. (Mucropalpus fallax Rambur, 



Histoire naturelle des Insectes, 1842, pag. 422; Neurorthus 

 iridipennis Costa, Atti dell' Accademia di scienze fisiche e 

 matematiche. Vol. 1, 1863, pag. 32, pi. Ill, fig. 7; Sartena 

 amoena Hagen, Ann. Soc. Ent. de France, 1864, pag. 41). 

 Of this very interesting insect there is a fine series. 

 The species was originally described by Rambur and 

 Costa from Sardinian specimens, and later on, by H a - 

 gen from Corsican examples. Since R. Mac Lachlan 

 (Trans. Ent. Soc. Lond. 1898, pag. 163) records it from 

 Algeria and Bulgaria. 



6. Megalomus pyraloides Ramb. A single specimen was 



present.
