very large colony of Solenopsis debilis in the nest with them ; 

 this is not a very common ant here. I also find with them a 

 mite Gamasus sp. L. , parasitic upon this ant. 



Campo7iotus pidus. Forel. — Living in a decayed hard pine 

 stump, a very large colony July 8th. They were winged specimens 

 at this time, with cocoons and larva of various stages of develop- 

 ment ; this is quite a common species. 



Camponotus castaneus, var. avtericanus. — Lives under stones. 

 I have as yet only found one colony. This one I found April 28, 

 1894, the males and females having wings; they must have hi- 

 bernated in this slate through the Winter. 



Camponotus sp. hybernating under the bark of dead pine trees, 

 March 18, 1894. 



Formica fuscata. — Living under stones; is quite a common 

 species. I have found some very pretty mites with them, which 

 are as yet undetermined ; two different species of Coleoptera are 

 found with them — Blapstiyius moestus and Megilla maculata. 

 This last species was of a very much faded color, quite small, 

 and had a very peculiar deformity of the right elytron, it being 

 nearly a sixteenth of an inch shorter than the left one, also the center 

 row of spots does not unite properly, being drawn out of shape in 

 proportion to the shortness of the elytra. This same colony of 

 ants had three Termes flavipes with them. 



Formica obscuripes Forel var. — Living in mounds and under 

 stones, and is not very common. I find two different species of 

 mites upon this ant. A species of Gamasus, and the other a 

 Uropoda sp. I have not been able as yet to locate where the 

 Gamasus species attacked the ants, but the Uropoda species 

 fasten itself invariably to the intermediate pair of legs at the 

 base of the tarsal joint at the tibia. 



Formica exsectoides Forel. — Living in mounds; not common. 



Formica nitidive7itris Em. — Living under stones, a very com- 

 mon species with one colony. I found living with them at one 

 side of their nest Prenolepis parvula, males and females were 

 winged. May 4, 1894. A Gamasus and Uropoda sp. of mites 

 were on these ants. 



Formica nitidiventris Em. var. — Lives under stones, and is 

 quite common, and is parasited with Uropoda mites. 



Formica subsericeus Say. — Living in mounds and under stones, 

 Uropoda mite is on this ant quite commonly.
