TACH ARDIIN^E 
This subfamily includes only a single known genus, which 
is sufficiently characterized in the key to subfamilies. 
Genus TACHARDIA R. Blanchard 
This genus is now represented in the Philippines by two 
species, of which one has been previously reported from India, 
while the other is described as new in this paper. These species 
may be separated by the following key. 
Key to the Philippine species of Tachardia. 
a 1 . Apex of spiracular processes or stigmatic plate large, circular or 
oval, with a broad chitinized area surrounding the central region 
containing numerous minute pores and about four to eight large 
tubular ducts, but no spines; posteriorly, near the anal lobe pro- 
cess, with several ball-like clusters of multilocular gland pores ; 
plates surrounding the . anal ring numerous, deeply and irregularly 
incised at apices ; antenna very short and stout T. fici Green. 
a'. Apex of spiracular processes smaller, with a ridge surrounding a cir- 
cular to oval area containing from two to six scattered pores and 
from nine to eleven conical spines, but no tubular ducts; without 
multilocular disk gland pores, except those near the spiracles; with 
sixteen clusters of peculiar gland ducts around the body margin; 
with only two plates and a few heavy spines around the anal ring; 
antennee, while reduced, longer, fingerlike T. minuta sp. nov. 
Tachardia fici Green. 
Tachardia fici Green, Ind. Mus. Notes 5 (1903) 97. 
This record is based on specimens collected at Manila from 
the aerial roots of a banyan tree (coll. Compel 20157). 
This species appears to be very closely related to the common 
lac insect, Tachardia lacca Kerr.
