Aulacorthum circumflexum (Buckton), also from Tantalus, agree 
very well with North American specimens from Clemson Col- 
lege, South Carolina and Los Angeles, California. The wings 
of these specimens are clearer hyaline than in the North Ameri- 
can specimens, the scape and pedicel are paler and in the female 
from A. circumflexum the wings are small and narrow, but 
agree in this respect with all males that I have seen from the 
United States, and also with one female from Los Angeles. In 
both of these females with small wings the abdomen 1s con- 
siderably blackened except at the base.
