486 SUBFAMILY X. CURCULIONINJE. 



Posey County, lud., rare, May 4. Dunedin, Fla., March 25 

 Apr. 11. Ranges from Maryland to Oklahoma, south to Florida 

 and Texas. Known as the "cow-pea cnrculio," the larvae breeding 

 in the pods of cow-peas and closely related legumes, sometimes 

 attacking the stems of cotton and often mistaken for the cotton- 

 boll weevil, Antlwnomiis grandis Boh. When full-grown the 

 larva cuts a hole in the pod, drops to the ground and pupates at 

 a depth of one to four inches beneath the surface. About a month 

 is required from egg to maturity. The adults hibernate beneath 

 rubbish and earth and emerge in May and June. One of the many 

 interesting Austroriparian species that find their way up into 

 southwestern Indiana.
