The species was discovered on a roedeer at Yen-an Fu, Shensi, by Capt. 
H. E. M. Douglas on January 19th, 1909. The much distended females were 
‘taken from the nostrils of the Roedeer. . . . . . Several roedeer were 
shot in the district, but nothing more of the kind was noticed.” 
The males were ‘‘taken from the skin of the same Roedeer”’ on which 
the distended females were found. 
A small series of both sexes was obtained.
