(Sp. 287) Ptinella Proteus. 
Of this Ptinella, so abundant locally beneath the damp 
rotting bark of trees within the cultivated districts of 
Madeira, it appears necessary once more to alter the 
name under which it must be cited,—Mr. Matthews 
having received types from Dr. Heer which prove it to 
be conspecific with his T'richopteryx testacea. Its sy- 
nonymy, therefore, so for as I am able to ascertain, 
would seem to be as follows; though whether the species 
is truly distinct, as I very much doubt, from the one 
which I have quoted on Mr. Matthews’ authority (vide 
Col. Atl. 102) as the P. aptera, Guer., from the Canarian 
archipelago I will not undertake, at any rate until Mr. 
Matthews’ Monograph has been published, to decide.

(Sp. 311) Meligethes echit. 
I think it very doubtful whether the few Canarian 
examples which were taken by the Messrs. Crotch in
