106 [October, 



Agrion puella, L. — Two £, Sao Marcos da Serra, 22nd May. 



Agrion Lindeni, Selys. — One <$ from Aldea de Neuves, 8th May, 

 one $ near Lisbon, 23rd April. 



Pyrrhosoma minium, Harris. — One $ from the slopes of Picota, 

 20th May, three J , Ponte de Morcellos, 14th June. 



N.B. — Of the fifteen species of Dragon-flies here recorded, the 

 following were indicated as Portuguese by De Selys in his " Eevue 

 des Odonates," 1850, viz. : S. striolatum, 0. forcipatus, C. hcemor- 

 rJwidalis, and I. Graellsi, but he noticed thirteen other species not 

 caught by Mr. Eaton, so that twenty-eight species have now been re- 

 corded for the Portuguese Fauna. 



All the fifteen species have been noticed in Spain, excepting G. 

 Graslini and A. Irene. The number of recorded Spanish species is 

 about forty-three, most of which no doubt also occur in Portugal. 



PLANIPENNIA. 

 SIALIDJE. 

 Sialis lutaria, L. — One $ , Cintra, 27th April, in the ordinary 

 condition. There is also one <$ from near Salamonde, 2003 feet, 30th 

 June, that I refer here with some hesitation. It has the dark colora- 

 tion of S. fuliginosa (and even intensified), yet the anal structure is 

 that of lutaria, only that the terminal ventral lobe appears slightly 

 shorter, and slightly less obtuse at its apex. It is distinctly not the 

 Spanish S. nigripes,~Ei&. Pict. (which I cannot separate from fuliginosa, 

 vide ante, p. 62). At present, therefore, in the absence of sufficient 

 materials, I am forced to consider it lutaria, with jDossibly slight modi- 

 fication in the anal parts, and with the coloration of fuliginosa. 



CONIOPTERYGIDiE. 



Coniopteryx aleyrodiformis, Stephens. — Two examples from Olivaes, 

 near Lisbon, 24th April, two from Cintra, 27th April. The antennae 

 are about 30-jointed, but in one sex (perhaps the $ ) the joints are 

 shorter and thicker than in the other. Supposing this to be an actual 

 sexual difference, it is clear that C. tineiformis must be distinct, and 

 not a sexual form as I was once inclined to believe. 



OSMYLID^. 



Sisyra Dalii, McLachlan. — Ten examples, nine from near Cintra, 

 31st May and 1st June, one from between Almodovar and Sao Barnabe,
