Schencki, Em. 



Otiorhynchid/E. 



Otiorhynchus ovatus, L. — With Formica fusca, L., var. subsericea, Say. 

 I have found this species in Massachusetts with :

 Aphaenogaster fulva, Rog.; and 

 Lasius americanus, Em. 



SlAPHYLINIDiE. 



Scopteus exiguus, Er. — With Formica fusca, L., var. subsericea. Say. 

 Aleocharini g. et sp. — With Solenopsis molesta. Say. 



PSELAPHIDiE. 



Ctenistes piceus, Lee. 



SCYDM^NID^. 



Scydmpenus bicolor, Lee. 



These two last species were collected by Mr. Crew in company with 

 ants ; but he did not at the time of capture deem it important to 

 save any, so we cannot give the names of the ants. C. piceus was 

 found March 23, 1895, and S. bicolor, Dec. 4, 1895. 



Hymenoptera. 

 Proctotrypid^. 

 Proctotrypes californicus, Holmgr. — With Formica fusca, L., var. subseri- 

 cea, Say. This, with a few other species of my own finding, are in 

 the collection of the National Museum at Washington, by request 

 of Prof. Howard.

? Halictus confusus. Smith. — With Formica fusca, L., var. subsericea, 

 Say. 



Cynipid^. 



9 Figitodes 5-lineatus, Say. — With Tapinoma sessile. Say. 



I have found Aphaenogaster fulva, Rog. ; Lasius flavus, L., and 

 Lasius americanus, Em., to collect oak galls late in the fall. Two 

 individuals came out of one lot of galls collected by L. flavus, L., 

 in about two weeks after I collected them, and have been determined 

 by Mr. Ashmead as Periclistus piratus, O. S, The ants lap the galls.
