The Canadian National Collection (Ottawa) has one of the 
largest, if not the largest collection of neotropical Amiseginae in the 
world. In a sample of about 700 unidentified specimens sent to me 
by Lubomir Masner from this collection there were many new taxa, 
including representatives of a new genus. In addition, material was 
borrowed from the Museum of Comparative Zoology, Harvard 
University (J. M. Carpenter), Cambridge, Massachusetts, the Amer- 
ican Entomological Institute, Gainesville, Florida (H. Townes, 
Gainesville), and the U.S. National Museum, Washington, D.C. 
(K. V. Krombein, Washington). The new species of Adelphe are 
described separately (Kimsey 1986). The remaining new taxa are 
included below. 
The following abbreviations are used: F = flagellomere, MOD = 
midocellus diameter, PD = puncture diameter and T = gastral 
tergum.
