a 2 . Head and thorax without white stripes. 
6 1 . Pterostigma of forewing wanting; antennae one and one-half times 
as long as body (without wings) ; forceps distinctly shorter than 
anal valve; much of thoracic dorsum red. (Formosa.) 
E. rubrofasciata Kuwayama (’08: 179). 
b 2 . Pterostigma large; antennae about as long as body (without wings) ; 
forceps longer than anal valve; thoracic dorsum orange yellow. 
(Philippines and Malay Archipelago.) 
E. forcipata Crawford (’17: 167). 
Epipsylla pulchra Crawford (’13; 297). 
This species has been taken by C. F. Baker at three stations 
in the Philippine group ; namely, Los Banos and Baguio, Luzon ; 
and Davao, Mindanao. Frederick Muir has taken one male on 
Amboina, in the Moluccas. This specimen has all the charac- 
teristics of the Philippine specimens except that the forceps of 
the male genitalia have a much smaller tooth on the inner face. 
Epipsylla forcipata Crawford (T7 : 167). 
The type locality of this species is Puerto Princesa, Palawan, 
Philippine Islands. The distribution seems to be wider, how- 
ever, for a single female has been taken by C. F. Baker on 
Penang Island. 
Genus PSYLLA Geoffroy 
This genus is a large one and is widely distributed. Its tax- 
onomic definition is not wholly clear, as it embraces at present 
species which probably should properly not be included. Several 
Australian species, for example, and a few Asiatic species are 
probably generically distinct but at present are not separated. 
A full description and a discussion of the genus are given in my 
monograph of this family. 
In the following key an attempt has been made to include 
all described species of the South Pacific, Australia, southern 
Asia and its islands, including Formosa, and the Philippine and 
Malay Archipelagoes. Many of these species are known to me 
only by their descriptions, so that the key must be more limited 
in value than it might be otherwise. 
Key to the species. 
a 1 . Forewings hyaline, clear, not colored, veins usually brown or black. 
b\ Body bright red; antennae about two and one-half times as long as 
width of head. 
c\ Genal cones longer than vertex; male forceps spatulate, broad at 
apex; antennae and legs reddish. (Philippines.) 
P. colorada Crawford (’17: 170). 
c 2 . Genal cones shorter than vertex; forceps acutely pointed; antennae 
and legs whitish. (Formosa.) .... P. coccinea Kuwayama (’08: 171).
