LECANIINA. 
Platylecanium n. gen. 
Female flat, broad oval, without waxy covering; antennz small or rudimentary; 
legs absent; ventral surface in abdominal region with groups of pores arranged in a 
semicircle, in the centre of which is the anal aperture; marginal bristles small and 
simple. Type, Platylecanium cribrigerum (Neolecanium cribrigerum, C. & R., Bull. 
Amer. Mus. Nat. Hist., XXXIV, p. 110). 
When P. cribrigerum was described as a Neolecanium, it was remarked 
that it probably deserved to rank as a distinct genus. Mr. E. E. Green has 
lately described a strictly congeneric species, Platylecaniwm pseudexpansum 
(Lecanium pseudexpansum Green, Bull. Entom. Research, V, 1914, p. 233) 
from Australia, and this seems to justify the separation of the genus. We 
are indebted to Mr. Green for cotypes of his species, which averages larger, 
and has better developed antenne. 
The following Lecaniinz have been received from Prof. Baker, who 
collected them in the Philippines. (L. B. = Los Bajios.)
