NEW SPECIES OF MECOPTERA FROM 
NORTHWEST CHINA 1 
By Fung Ying Cheng 
Taiwan Agricultural Research Institute 
The Mecoptera or scorpion flies described in the present 
paper were mostly collected by Prof. Io Chou, Mr. Tien 
Ho Hei and the writer in Sikang Province during the 
course of an insect pest survey for the scientific expedi- 
tion of the Sino-British Committee in 1939. Other speci- 
mens were sent to me by Prof. Io Chou, Mr. Chuan Lung 
Lee and Mr. Chia Chu Tao, to whom I am deeply indebted. 
In this paper, seventeen new species are described, in- 
cluding one previously identified by Dr. Tjeder as cor- 
nigera. 
In describing the new species, I have followed the termi- 
nology of R. E. Snodgrass in his “Principles of Insect 
Morphology” (1935) and F. M. Carpenter in his “Re- 
vision of the Nearctic Mecoptera” (Bull. Mus. Comp. 
Zool. 1931, 72; 205-277), viz., coxopodites (“basistyles”), 
harpagones (“dististyles”), hypandrium (“lower ap- 
pendage”), hypovalvse (branch of hypandrium), preepi- 
proct (“upper appendage or epiandrium”), parameres 
(“ventral valves or tittilators”) and sedeagus (“dorsal 
valves”) for the males, and subgenital plate and internal 
skeleton for the females.
