Hydrot^a, Dsv. (459) 

 This character distinguishes males of Hydrotcea from 

 all other Anthomyids. For the females, Herr Stein 

 gives the following characters, when all taken 

 together, as marking them off from all other 

 female Anthomyids, except Ophyra : 



The frontal stripe exceedingly broad, the orbits 

 therefore extraordinarily narrow; frontal bristles 

 present, and crossed ; four post-sutural dorso- 

 central bristles ; sternopleural bristles, 1, 1, that is 

 two strong bristles, one near the upper fore corner 

 and one near the upper hind corner; fore tibiae with- 

 out bristles ; the arrangement of bristles (chcetotaxy) 

 on the hind tibiae simple ; abdomen never spotted.
