Holotype (c?) : Omei (11,000 ft.), Szechuan, China, 
July, 1936 (D. C. Graham) ; in the IJ. S. National Mu- 
seum. This is the specimen which I illustrated under 
the name diceras McL. in 1938, figures 2 and 10. 
Allotype (?) : near Tachienlu (5000-8500 ft.), 
Szechuan, China, June 18-July 12, 1923 (D. C. Graham) ; 
in U. S. National Museum. This specimen was illustra- 
ted in the same paper (1938), figure 11. 
Paratypes : 1 <?, Suifu, Szechuan, China, Oct. 1, 1929 
(D. C. Graham) ; in IT. S. National Museum. 1 $, west 
of Yachow (2000-7500 ft.), Szechuan, China, June 14-18, 
1922 (D. C. Graham) ; in U. S. National Museum. 1 
same collection data as last, in Museum of Comparative 
Zoology. 1 $, same collection data as allotype, in U. S. 
National Museum. 2 ?, 9 miles southwest of Tachienlu 
(9000-11,000 ft.) Szechuan, China, June 25-27, 1923; in 
Museum of Comparative Zoology. 
There is an additional female, in poor condition and not 
designated a paratype, from 30 miles north of Tachienlu, 
Szechuan, 12,000 ft., July 5-9, 1923 (D. C. Graham). 
This species, which I have named for Mr. D. E. Kim- 
mins of the British Museum (Natural History), belongs 
to the diceras group of Panorpa , but differs from the 
other species included there by the curved forceps and 
peculiar configuration of the ventral valves of the male.
