* Hydropsyche lepida^ Pict. — Ponte de Morcellos, 12tli June. 



Sy dropsy che (?) tibialis, McLach. (n. sp.). — One damaged $ f rom 

 near Sao E-omao, 4100 ft., 5th June. 



Possibly not a true Hydropsyche ; differing in the form and pro- 

 portions of the joints of the maxillary palpi, and in the undilated 

 intermediate tibiae and tarsi of the $ . A very interesting insect, the 

 acquisition of the J* of which is desirable. 



* Diplectrona felix, McLach. — Monchique, slopes of Poia, Villa 

 Eeal, and Salamonde, May and June. 



Philopotamus perversus, McLach. (n. sp.). — Yilla' Peal and Eui- 

 vaes, end of June. Might be considered a melanic variety of Fh. 

 montanus, in external characters. A distinct difference therefrom 

 exists in the inner anal structure. 



* Pliilopotamus montanus, Donovan. — Villa Peal, four examples. 

 Scarcely typical. 



Pliilopotamus amphilectus, McLach. (n. sp.). — The Estrella (Cea, 

 &c.). A large handsome species, with the external anal structure oi 

 montanus, and the inner structure of variegatus ; on the whole more* 

 allied to the latter. A solitary <^ from Villa Peal (probably the more^ 

 typical), differs in some slight colour-characters. 



Dolophilus corvinus, McLach. (n. sp.). — A pair from Sao P.omaoi 

 9th June. Allied to D. pullus, McLach., but with very decided struci 

 tural differences. 



* Wormaldia mediana, McLach. — Cea, Ponte de Morcellos and Villi 

 Eeal, 11th, 14th, and 21st June, 8 examples. Slightly doubtful, beinp 

 darker than the typical form, but hardly to be referred to W. sub 

 nigra. 



Two J examples of this genus, from Villa Peal and Salamondi 

 respectively, remain undetermined. 



Plectrocnemia inflata, McLach. {n. sp.). — One J" from near Villi 

 Eeal, 1280 ft., 24th June. Allied to P. geniculata, McLach. 



Plectrocnemia Icetahilis, McLach. — One ^ from near Villa EeaJ 

 22nd June. The types were from the French Pyrenees. 



* Polycentropus Kingi, McLach. — I am unable to separate example 

 from the slopes of Poia, near Alferce, Cea, and Villa Eeal, froD 

 typical Scotch specimens ; they are rather larger. As I saw as
