Onap. XVI. PINGUICULA LUSITANIUA. 391 
insects and fragments of insects adhering to almost all 
the leaves. These consisted chiefly of Diptera, with 
some Hymenoptera, Homoptera, Coleoptera, and a 
moth. On one leaf there were nine dead insects, 
besides a few still alive. He also observed a few truits 
of Carex puliearis, as well as the seeds of this same 
Pinguicula, adhering to the leaves. I tried only two 
experiments with this species; firstly, a fly was placed 
near the margin of a leaf, and after 16 hrs. this was 
found well inflected. Secondly, several small flies were 
placed in a row along one margin of another leaf, and 
by the next morning this whole margin was curled 
inwards, exactly as in the case of Pinguicala vulgaris. 
PINGUICULA LUSITANICA. 
This species, of which living specimens were sent me 
by Mr. Ralfs from Cornwall, is very distinct from the 
two foregoing ones. The leaves are rather smaller, 
much more transparent, and are marked with purple 
branching veins. The margins of the leaves are much 
more involuted; those of the older ones extending 
over a third of the space between the midrib and the 
outside. As in the two other species, the glandular 
hairs consist of longer and shorter ones, and have the 
same structure; but the glands differ in being purple, 
and in often containing granular matter before they 
have been excited. In the lower part of the leaf, almost 
half the space on each side between the midrib and 
margin is destitute of glands; these being replaced by 
long, rather stiff, multicellular hairs, which intercross 
over the midrib. These hairs perhaps serve to prevent 
insects from settling on this part of the leaf, where 
there are no viscid glands by which they could be 
caught; but it is hardly probable that they were 
developed for this purpose. The spiral vessels pro-
