222 ENTOMOLOGICAL NEWS. [September, 



Formica pallida fulva, var. of nitidiventris. Uropoda and 

 another undetermined mite are found on these ants; not very 

 common. 



Formica neogates Em. — Lives under stones, and is not common. 



Formica integra Nyl. — Lives under stones, not common. 



Formica sp. — Not a common species, and have upon them an 

 undetermined mite. 



Lasius niger. — Lives under stones, very common. 



Lasius neoniger Em. — Lives under stones, very common ; in 

 one of their nests I found a larva of Galerita sp. It was in a 

 small hole by itself; the mite Uropoda sp. is found on this ant. 



Lasius interjectus Neyr. — Lives under stones, very common. 

 Solenopsis debilis lives at one side of the nest with them. 



Lasius claviger Rog. — Lives under stones, very common. 

 Soleywpsis debilis lives at one side of the nest with them ; they 

 had with them, May 24, 1894, two different species, of Aphids, a 

 species of Forda, and a mealey bug of Westwoodia, in large 

 numbers; this ant is also parasited with the Gamasus sp. 



Lasius species undetermined, found under stones with Campo- 

 notus americanus ; very rare. 



Lasius species not determined, found under stones occasionally, 

 parasitized by Gamasus species. 



Aphcenogaster fulva Rog. — Lives under stones, not very com- 

 mon. 



Tapinoma sessile, found living upon the upper outside edge of 

 a robin's nest upon an apple tree, ten feet from the ground. The 

 nest had three eggs in it at the time, and must have been an old 

 nest, because there were nearly full-grown larvae of the ants at 

 this time, July 8, 1894. It is also found occasionally under stones. 



Cremastogaster lineolata Say. — Lives under stones and very 

 common; also found in stumps and under wood piles, and in 

 bark of pine trees. I found one nest under a large cord wood 

 stick in the woods; this colony -had six live shells of Zonites 

 arboreus Say. The ants were all collected around them appar- 

 ently feeding from the slimy substance produced by the snails in 

 the shells. I have also found some of the empty shells of Val- 

 Ionia pulchella nule with this ant. 



Prenolepis parvula Mayr. — Living under stones, a common 

 species; a mite Uropoda was found on this ant.
