Had I only Motschoulsky’s short observation (which 
takes the place of a diagnosis) to judge from, I should 
have been utterly unable to form any idea whatsoever 
about this nevertheless well-marked little Acrotrichis ; 
but since so high an authority as Mr. Matthews is satis- 
fied that it must pertain to a minute species of which I 
captured many examples, amongst refuse, in a garden in 
Funchal, I am content to cite it accordingly. It is the 
smallest Acrotrichis proper which has hitherto been de-

larger than the Nephanes Titan; and my specimens were 
all of them taken by sifting rubbish in the garden of the 
Quinta dos Jasmineiros, on the western outskirts of 
Funchal. Motschoulsky’s ‘‘description” of it is as 
follows :—‘ Forme et coleurs voisines de celles de la de- 
pressa, Gillm., iv. 3, mais un peu plus petite et plus con- 
vexe, élytres et antennes plus courtes, les premicres plus 
rétrécies vers la base ; ponctuation assez forte, pubescence 
éparse, antennes obscures.”

This Canarian Ptenidiwm was originally identified by 
Mr. Matthews (apparently from Erichson’s diagnosis) 
with the European P. levigatwm of Gillmeister; but Mr. 
Matthews now informs me that, having since received
