Summary 
The male genitalia of 8 genera of Oxyhaloinae show remarkable 
basic uniformity of characters, especially in the structure of L2d and 
the marked reduction in Li. Differences in characters of the genital 
hooks (R2) were used to separate the genera into three tribes as 
follows : 
1. Oxyhaloini. — Oxyhaloa. 
2. Nauphoetini. Nauphoeta , Griffiniellcij II enschout edema. Leu - 
cophaea, and J agrehnia. 
3. Gromphadorhinini. — Gromphadorhina and Aeluropoda.
