itudent of Trichoptera, I fear it will be long before another so im- 

 portant a contribution to this portion of the Portuguese insect-fauna 

 ?an appear. 



I have indicated by an asterisk {*) those species that also occur 

 .n Britain. 



LIMNOPHlLIDiE. - 



Catadice estrellensis, McLach. {n. sp.). — South of Sabugueiro, 

 4092 ft., 5th June, 3 c^^, 3 ? . The second species of this Drusus-gYOU^ 

 genus. Apparently quite distinct from the Spanish G. Bolivari, 

 McLach., which was described from a single badly-preserved (^ . 



SERICOSTOMATID^. 



j! Sericosfoma Bceficum, Ed. Pict.— About 25 examples from the 

 ^opes of Picota and other localities near Monchique in May, and 

 near Cea, Villa Eeal, and Salamonde, in June, at elevations ranging 

 from 1400 to 2000 ft. These shew considerable variation in the form 

 of the penis-sheaths, apparently due to local influences. 



i 



ScUzopelexfestiva, Eamb.— A long series from near Yilla Eeal, 

 24th and 25th June. Although from one locality, only a few examples 

 show the typical markings on the anterior-wings ; in others they are 

 nearly obsolete ; and in the majority these wings are uniformly yel- 

 low, suggestive of ^^. grcmjce, Ed. Pict., which should, liowever, be 

 structurally distinct, according to the description. 



Micrasema morosuvi, McLach. ? — 1 refer here, provisionally, about 

 15 examples collected near Cea, Sao Eomao, Cintra, and Axilla Eeal. 

 The species of Micrasema are amongst the most difficult to define. 

 The types of M. morosum were from Cariuthia. 



Micrasema 7noestum, Hagen.— Originally described from 1 ? from 

 Spain. Eaton collected a series near Monchique, on the slopes of 

 :Foia, and near Villa Eeal and Euivaes, that in all probability belong 

 here. 



Helicopsyche Jusitanica, McLach. {n. sp.).— Six ^ ^"^^^^ ^^^ slopes 

 of Picota, near Monchique. All in alcohol (excepting one damaged 

 'example), and with no possibility of defining the colour of pubescence, 

 '<fec. Allied to the Italian R. sperata, McLach., but apparently quite 

 distinct. Mr. Eaton did not discover the larvse, but it is just possible 

 that the cases from Portugal to which Hagen (Stett. Zeit., 1864, p. 

 1130) applied the name " «^r/m7," may belong here. I have already
