longer than the funiculus in the male and about equal in length to the 
funiculus in the female. 
Birds are known to feed on the adults of this species. McAtee 
(1908, pp. 26 and 44) reports cardinals and rose-breasted grosbeaks 
feeding on Anomala binotata and Beal (1912, pp. 17 and 54) cites the 
kingbird and yellow-bellied fly catcher. The writer found one speci¬ 
men in the stomach of a toad taken in a corn field in May. 
To summarize, the adults of Anomala binotata are injurious to fruit- 
producing plants and the grubs are minor pests of corn, wheat and 
oats. The winter is passed as an adult. Eggs are laid in the spring 
and soon hatch, producing larvae whose average time of develop¬ 
ment was found to be 83 days. The pupal stage lasts on an average 
16 days. The adults transform in the fall and remain in their pupal 
cells until the following spring, thus completing a one-year life cycle.
