while in subulatus they are mainly black. 
ADDITIONS TO MY CATALOGUE OF THE DESCRIBED DIPTERA 
WITH REDUCED OR ABORTED WINGS. 
Most of the following species have been described subse-

records have been previously overlooked by me. 
With the following 45 additions the number of cases 
observed (corresponding exclusively to degrees 3-8 of my 
gradation, pp. 99-110) amounts to 384.
