and one near Lithob'ncs. The Polydesjnus ^.nd /itlus are vegetarians, the 

 Lithobius is carnivorous." 



Similar bolls collected at Mansura, La., March i and 2, 1909, directly 

 after my visit at Alexandria, were found to harbour quite different species, 

 and the list affords an interesting comparison.

OTHER ORDERS. 



Dicymolomia julianalis Wk. — (Det. H. G. Dyar.) A larva in hanging 

 boll damaged by Arcp,cerus fasciculatiis matured after isolation in a breeding 

 jar. So far as known to me, the only published record of the occurrence 

 of this lepidopterous species in cotton bolls is the statement of Dr. Dyar in 

 Proc. Ent. Soc. Wash., v. XI, 1909, p. 66, though in habits it is con- 

 sidered as a scavenger. 



Batrachetra Rileyi Wishm. — Larvae of this moth were frequently 

 found in fallen bolls associated with and vvithout ArcBcerus fasciailatus or 

 its vvoik. The larva is supposed to feed on insect remains. (See 

 Additional Records.) 



Crejuastogaster Imeolata Say, subsp. htvhiscula Mayr, var. clara 

 Mayr. — A solitary female of this ant in hanging boll, and five incipient 

 colonies, composed of female, workers and young larvae, in similar bolls. 



Dorti luteipennis Serv. — (Det. A. N. Caudell.) Adults of this earwig 

 in both hanging and fallen bolls. 



Schcefiojnyza chrysostoma Lw. — (Det. D. Coquillett.) Adult fly from 

 hanging boll emerged in breeding jar, March 19.
