are easily recognizable by their generally dark color, 
thickened antennae and slightly broader anterior lobe of 
the prothorax, this lobe having a fine median groove. 
Samples from other areas are not as obvious. The general 
color may be paler, the antennae not so obviously thickened 
and the anterior lobe of the pronotum not canaliculate. 
Specimens from other areas than the Appalachians are 
most easily identified by the form of the male genitalia, 
as shown in the key and figures. 
This is apparently the common species in the southern 
Appalachians but it is apparently rather scarce elsewhere 
in its range. Specimens have been seen from coastal South 
Carolina, Virginia, Indiana, Illinois, eastern Kansas and a 
single specimen from the state of Washington. The com- 
bination of the southern Appalachians and Washington 
in its distribution suggests a relict distribution such as 
has been noted in some other groups of insects. No other 
species is known from west of the 100th Meridian in 
North America. The Washington specimen was taken by 
G. H. Nelson, an entomologist known for his attention to 
detail. There can be no question that the locality label is 
correct. 
Specimens have been examined from the following 
localities: Illinois: White Heath, Piatt Co., Apr. 1, 
July 20, Sept. 23, Oct. 12, Oct. 29, No. 7, in soil and humus, 
J. C. Dirks. Indiana: Vermillion Co., Aug., W. S. Blatch- 
ley. Kansas: Atchison, Apr. 25, H. Soltau; Topeka, Sept. 
10, 1942, C. H. Seevers. North Carolina: Asheville (type 
locality) ; L. Toxaway, A. T. Slosson; Valley of the Black 
Mountains, July, Sept. 24 and 30, 1900, Aug., Sept. 10-14, 
1906, W. Beutenmuller. South Carolina: Florence, Jan. 
18. Virginia: Fairfax Co., Sept., Quirsfeld. Washington: 
Deep Lake, (Douglas Co.), May 5, 1949, G. H. Nelson.
