THE CANADIAN ENTOMOLOGIST. 25 



INSECTS TAKEN IN DRY CORNSTALKS. 



Examinations of cornstalks in the same localities and on the same 

 dates as mentioned for cotton bolls failed to disclose a single cotton-boll 

 weevil, although the finding of this insect in stalk cavities probably formed 

 by Arcecertis fasciculaius had been previously reported by the overseer of 

 a plantation near Alexandria. The latter species was found to have bred 

 extensively in the stalks, a large proportion of which, in consequence, 

 presented a riddled condition on account of emergence holes opening from 

 the larval excavations in the pith. These cavities afforded attractive 

 retreats for other species, mainly in hibernation, and including common 

 weevils that are apt to be mistaken for boll weevils. 



The species thus found at Alexandria, La., are herewith recorded. 



COLEOPTERA. 



Languria niozardi Lat. — Adults mostly in cavities of Arcecerus 

 fasciculaius. 



Silvafiiis bidentatiis Fabr. — Adults all in A?cecerus cavities. (See 

 Additional Records.) 



Paromalus cotijunctiis Say. — Adults in broken stalks on ground. 



Carpopkilus hemipterus L. — Adult in A7'CBceriis cavity. 



Moticrepidius belliis Say. — Adults in broken stalks on ground. 



Atcenius abdiitis Hald. — (Det. E. A. Schwarz.) Adult in broken 

 stalk on ground. 



AtcEiiiiis cognatus Lee. — (Det. H. S. Barber.) Adult in broken stalk 

 on ground. 



Myochrous denticoUis Say — Adults rather common in Arcecerus 

 cavities. (See Additional Records.) 



Chcetoc?ie?na deiiticiilata III. — Adult in Arcecerus cavity. 



TaJiymecus confertus Gyll. — Adult in Arcecerus cavity. 



Eudigogtis roseiischoeldi Fah. — Adults in broken stalks on ground. 



Chalcodervius ceneus Boh. — In one field wholly in Arcecerus cavities ; 

 cowpeas had been grown in this corn field. In another field, found in 

 broken stalks not attacked by Arcecerus fasciculaius. Common, and apt 

 to be mistaken for the boll weevil. 



Calaudra oryzce L — Adults commonly found in stalks not attacked, 

 as well as in Arcecerus cavities. Apt to be mistaken for the boll weevil.
