NOTES ON CHINESE PANORPID^E 
(MECOPTERA) 1 
By F. M. Carpenter

Panorpa die eras was described by McLachlan in 1894 
from Szechuan, China. Lack of knowledge of the geni- 
tal structures of the male type, which has been in private 
hands and inaccessible for many years, has prevented 
recognition of the species, though both Dr. Tjeder and I 
attempted it. Acquisition of the McLachlan collection 
by the British Museum (Natural History) in 1938 has 
finally made the type available for study, and in reply to 
my request for information about it, Mr. D. E. Kimmins 
very kindly sent me two drawings, which enable recog- 
nition of the insect. Since it is now apparent that both 
Dr. Tjeder and I have misidentified diceras, I include 
here an account of its structure and of the taxonomic 
changes involved.

Panorpa diceras McLachlan, 1894, Ann. Mag. Nat. Hist., 
13 : 423 [nee P. diceras Tjeder, 1935, Arkiv for 
Zoologi, 27A(33) : 7; nec P. diceras Carpenter, 1938, 
Proc. Ent. Soc. Wash., 40: 270). 
Panorpa grahami Carpenter, 1938, Proc. Ent. Soc. 
Wash., 40 : 272, figs. 5, 9. 
The drawings of the genital bulb of the type sent by 
Mr. Kimmins are reproduced in the accompanying fig- 
ure. A comparison of these with Dr. Tjeder ’s illustra- 
tions of his species, and with my drawings (1938) of the 
supposed diceras reveals obvious differences, especially 
in the form of the hypovalvae and ventral valves. On 
the other hand, comparison with my figures of the geni- 
talia of grahami leaves no doubt of the identity of this 
species with diceras . In other details of body structure, 
as well as wing coloring, grahami also agrees with Mc-
