[Dec. 
I wish to express my sincere thanks to Prof. S. F. Chin 
of National Peking University and Prof. S. Issiki of Na- 
tional Taiwan University for their encouragement during 
the course of my study ; and to Prof. F. M. Carpenter of 
Harvard University for his kindness in reading over this 
paper. 
Family P ANORPiDiE 
Genus Panorpa Linn. 
This genus is represented in China (not including For- 
mosa) by 17 species, which may be grouped into three 
categories on the structure of the 6th abdominal segment 
of the male, as shown by Carpenter. In the first or cen- 
tralis group, with a single anal horn, we have centralis 
Tjeder and flavipennis Carpenter ; in the second or dicer as 
group, with the double anal horn, we have dicer as McLach- 
lan, tjederi Carpenter, stotzneri Esben-Petersen and kim- 
minsi Carpenter ; in the third or davidi group, without the 
anal horn, we have a great number of species, i.e., davidi 
Navas, stigmalis Navas, cladocerca Navas, tetrazonia 
Navas, waongkehzeni Navas, tincta Navas, japonica Thun- 
berg, curva Carpenter and difficilis Carpenter. Two other 
species, guttata Navas and bonis Cheng are known only 
from the female, so that the position of these two species 
in the above grouping has yet to be determined.
