 portion of the epitorma, and surrounded with irregularly placed

Bolboceras alabamensis (Wallis) 



Odontaeus alabamensis Wallis, pp. 239-241. Type, male, Grand Bay, Ala., 

 March 1908, Loding (Wallis). 



So few specimens of this species have been collected that little has 

 been noted concerning its habits. Specimens in my collection from 

 the Emory University Field Station were all taken in light traps. 



Further study of other specimens might indicate a complex of forms 

 rather than a single species. I found some differences in male geni- 

 talia, but additional specimens are needed to satisfactorily establish 

 the variation within the species and to ascertain its habits. 



Specimens examined: 4 males, 5 females (1 female, no data, ANSP).
