162 THE CANADIAN ENTOMOLOGIST. 



No Carabidae are known to me to truly inhabit with ants, but several 

 species hibernate in their burrows whether inhabited or not, as Panagceus 

 fascidtus, which I find in autumn and in spring. 



Ptomophagus parasitus Lee. I take this beetle occasionally in April 

 on the under side of flat stones covering the formicaria of a large black 

 ant (Formica herculanea ? ). With this species of ant I once found five 

 specimens of Hister p/auipes, and Cremastochilus canalicidatus and 

 Harrisii are its guests. 



Co/on. The Classification, p. 77, states that some species of Colon 

 are found only in ants' nests, but I fail to find further bibliography. 



Scydmcenus. The Classification, p. 84, mentions ants' nests as the 

 residence of some of the species. It might be well for the collector to 

 consider whether the association is other than accidental. 



S. capillosus Lee. Is found in March on the under side of stones, and 

 is said (Pr., 6, 152) to sometimes occur in the nest of a small rufous ant 

 with red legs. I take it sometimes with various small ants but just as 

 frequently by itself, and see no connection besides that of occupying a 

 common shelter. Georgia, Pennsylvania and New York. 



6". brevicomis Say. Occurs in the nest of a small black ant. New 

 York and Pennsylvania. (Pr., 6, 153.) 



S. rasus Lee. Found with a small fuscous ant. Pennsylvania. (Pr., 

 6, I53-) 



Adranes coccus Lee. Found with a small black ant. June. Georgia 

 and Illinois. (B. J., 6, 84; N. S., p. 28 ) 



Adranes Lecontei Brend. Several specimens of this curious insect, 

 which is without eyes and has only two joints in the antennae, were taken 

 by Mr. Charles Dury near Cincinnati, Ohio, with a medium-sized pale 

 brown species of ant, inhabiting a decaying beech log. "On each side 

 of the body and just back of the elytra is a tuft of brown hair, and from 

 it springs a tube from which the beetle exudes a fluid that the ants are 

 supposed to eat." — 'Dury, Journal of the Cincinnati Society of Natural 

 History, July, 1884. 



Ceophyllus moni/is Lee. Inhabits here with a medium-sized, honey- 

 yellow ant (Lasius integerrimus ?) that nests under stones. When the 

 beetle is found, which is not often, from six to a dozen occur in the same
