rated from the more chitinized main iobes by a deep groove. Outer 

 forceps shinino; black, giving off a pair of blunt processes at base, 

 which project backward, the remainder long, extending forward and 

 curving downward, of uniform width to tip, which is rounded. 

 Inner forceps rudimentary, narrow, less than half as long as the 

 outer. In repose the closely approximated outer forceps evidently 

 lie in the median groove between the two soft inner lobes of the fifth 

 sternite.

 Described from 62 specimens of 

 both sexes: 34. including type 

 and allotype, were collected at 

 Suifu. Szechuen Province, China, 

 by Rev. D. C. Graham, after 

 wdiom the species is named; one 

 male from the same collector was 

 collected at the summit of the 

 range of mountains, Washan, 

 same Province ; and another male 

 at Yellow Dragon Gorge near Songpan, in the same Province, was 

 taken by the same collector at an altitude exceeding 12,000 feet. 

 From E. Brunetti were received two males taken at Hang Kow, 

 China, and two females from Hong Kong; while Prof. T. D. A. 

 Cockerell sent a female which he took at Kongaus, Siberia, in 

 August, 1923. 



The remaining 29 specimens were received from H. H. Keifer, 

 department of agriculture, California, who sent them in December, 

 1929, writing that he reared them all from a single batch of eggs 

 that he found on meat at Sacramento, Calif. Thus it appears that 

 the species has lately established itself in the United States. The 

 California specimens are dated June 10, 1929. No other North 

 American specimens are known.
