Pulvinaria. Four species and one variety have been reported 
from the Philippines, but I believe that the variety is invalid. 
Key to the Philippine species of Pulvinaria. 
a’. Marginal spines large, stout, cylindrical or slightly tapering, and trun- 
cate at apices pitavajatits ius Cates Ge cs P, thespesise Green. 
a’. Marginal spines more slender, acute apically, or flattened and incised 
or fimbriated, never truncate, and much slenderer than spiracular 
spines. 
b*. Spiracular spines in each group four or five, one longer than the 
others, very rarely with only three in a group; marginal spines 
slender, the apices more or less fimbriated........... P. polygonata Ckll 
b?. Spiracular spines in each group normally three, one longer than 
the other two; marginal spines more or less distinctly flattened 
toward apices and incised at tips. 
c’. Marginal spines typically flattened at apices, but not or only 
very slightly broadened, strongly incised; mature female appar- 
ently without dorsal secretion P. tyleri CkIl. 
ce, Marginal spines typically distinctly broadened and incised api- 
cally, as well as flattened; mature female with more or less 
cottony or waxy secretion dorsally.....................--. P. psidii Mask.

The truncate marginal spines and the numerous spiracular 
spines of this species, as shown in the accompanying figure, 
make it readily recognizable among the other Philippine species. 
The following is the record of the material examined: 
Luzon, Manila, on Samanea saman (coll. Compere), on 
Zizyphus jujube (coll. Arce 2571): Bulacan Province, Baliuag, 
on Jatropha cureas (coll. Arce 2607): Laguna Province, Los 
Bafios (coll. Banks 18465) : Rizal Province, Montalban, on Ho- 
monoia riparia (coll. McGregor).
