DISTRIBUTION. 
The literature of L. v. dorsatum shows that this form occurs 
in Pennsylvania, New York, District of Columbia, Illinois and 
Michigan. I also have specimens before me from Iowa (Gil- 
lette), Ithaca, New York. (Comstock and Banks), Lincoln, 
Nebraska, (Bruner), Maine, (Harvey), South Dakota (Aldrich) 
and a large number collected in the central and northern 
counties of Ohio, as well as in Vermont and New Hampshire. 
By the original describer the southern form (L. vittatum) is 
said to inhabit the southern States. Dr. Wood reports it from 
Texas and Nebraska, and I have already reported it from 
southern Illinois and Kentucky. It also occurs in southern 
Ohio, where it has been collected in Lawrence County, in 
August, 1888, and July and September, 1889, and in Warren 
County, where we took it during the summer of 1889. I have 
also received a number from Arkadelphia, Arkansas, collected 
in 1887; and Mr. Theodore Pergande has kindly sent me & 
number collected at Marshall Hall, Maryland, August 21, 1887. 
Prof. W. B. Alwood has added a few taken at Blacksburg; 
Virginia, and my brother, Howard Evarts Weed, has sent @ 
large number from Mississippi.
