Although inclusion here constitutes the first published description 
of Anypotacta czernyi, Garrett should be given credit for the species. 
This is done with the permission and sanction of Mr. Garrett.

This genus is characterized as follows: anterior fronto-orbital 
bristle shorter than posterior bristle, dorsocentral bristles 1+3, 
scutellum bare except for 2 pairs of lateral bristles, propleural bristle 
present, pteropleuron bare, 1 pair of prosternal bristles, middle tibia 
with dorsal preapical bristle and several ventral apical bristles. 
I do not agree with Czerny in splitting off Amoebaleria flavotestacea 
(Zetterstedt) and A. confusa (Wahlgren) into a separate genus, 
Chaetomus. The character used to separate the two genera in Czerny’s 
(1924) key, couplet 21, is the distance between the anterior and poste- 
rior fronto-orbital bristles. In checking this character among speci- 
mens of Amoebaleria I found considerable variation, even among 
specimens of the same species. ‘Thus it does not appear to be a suit- 
able character for use at the generic level. 
With few exceptions it is the structure of the male terminalia which 
will best distinguish the species of Amoebaleria. The illustrations 
accompanying the present paper may thus be more useful for male 
specimens than the following key. In the key I have purposely 
avoided, whenever possible, the use of characters involving terminalia, 
so that within limits it may be used for specimens of both sexes. 
Ficures 74-96.—Structures of the male terminalia of Amoebaleria and Heleomyza. All 
structures are shown in lateral view, except that of fig. 96 which is in ventral view.
