Tribe II. — Mutillini. 

 This tribe, to the initiated, is readily distinguished by the eyes, which 

 are usually quite differently shaped, rarely smooth and shining, and always 

 distinctly facetted, although a few females have small ellipsoidal or 

 somewhat rounded eyes, as in the tribes Photopsid'nii and Sphaerophthal- 

 mini, and therefore, if the greatest care is not given to other characters, 

 could be confused with certain genera in those tribes.
