1918, p. 503; 1920a, p. 40; 1926, p. 113; 1932, p. 83 —Fischer, 1963, pp. 164,

The photograph of the wings and the drawings of the male genitalia 
were made from the holotype male in the collection from Warsaw.

Leptonema cinctum Ulmer, 1905a, pp. 64, 65; 1907b, p. 163; 1907c, p. 54; 1913, 
pp. 398, 407.—Mosely, 1933, pp. 19, 20.—Tomaszewski, 1961, p. 3.—Fischer, 
1963, pp. 167-168. 
The wings of the holotype male seem to have the same pattern as 
those of the specimen figured by Mosely (1933, frontisp.). The geni- 
talia, however, show several distinct differences, especially in the 
structure of the tenth tergum. I have not seen enough material of 
the species to determine whether these differences are of specific value. 
The drawings of the genitalia were made from the holotype male 
in the collection from Warsaw. 
Leptonema columbianum Ulmer 
Leptonema columbianum Ulmer, 1905a. pp. 61, 62; 1907b, p. 163; 1907c, p. 51; 
1913, pp. 394, 407.—Banks, 1913a, p. 89.—Nawvas, 1917, p. 404; 1920a, 
p. 40; 1920b, p. 64; 1930, p. 182.—Mosely, 1933, pp. 13, 14.—Tomaszewski,

Lectotype, female: “Columbia Pehlke,”’ ‘‘Type,” “St. Z. 1905 p.

“Leptonema columbianum Ulmer Typus!” “Lectotype Leptonema 
columbianum Ulmer By Flint.” In Warsaw. 
The type specimens are all females with dilated mesothoracic legs 
as stated by Ulmer. There is no reason to believe that Mosely 
associated the wrong male with the species. His action issubstantiated 
by several series I have seen which contain both sexes. 
Leptonema furcatum Ulmer 
Leptonema furcatum Ulmer, 1905a, pp. 50, 51; 1907b, p. 161; 1907c, pp. 48, 49;

The lectotype of the species agrees closely with Mosely’s figures 
and is therefore not refigured. Although Mosely’s action (1939b)
