According to the knowledge at hand the range of D. nepalensis 
includes neither Europe nor Africa; otherwise it corresponds 
pretty closely with that of D. hirsuta. In certain parts of its 
range, such as the southern United States and the West Indies, 
it has been rarely collected; in other parts of its range, such as 
southeastern Asia, it seems to be more abundant. The following 
specimens have been examined :— 
GEORGIA: Forest Falls, Decatur County, 1901, R. M. Harper 
1193a (apparently mixed with D. hirsuta).
