A List of Indiana Ants. 



William Morton Wheeler. 



Many years ago Mr. W. S. Blatchley sent me for indentification a number 

 of ants collected in various parts of the state of Indiana. Owing to lack 

 of funds, my report on these insects was never published. Although the 

 list of species is undoubtedly incomplete, it seems ad^'isable to print it, with 

 such changes as the advances in ta.xonomy have rendered necessary, because 

 it contains a number of locaUty records that niaj- be useful in future studies 

 of the geographical distribution of our North American ants. 



FAMILY FORMICID^ 



Subfamily Ponerinae 

 Genus Siiginalovima Roger. 



1. (S. pallipes Haldeman. S — Wyandotte. 



A rather rare species which nests in small colonies in rich, damp woods, 

 under stones, leaf-mold, or more rarely under logs. 



Genus Pruceralium Roger. 



2. P. silaceum Roger subsp. rwjulosuvi Wheeler. S 9 — 

 Rarer than the preceding; nesting in rotten logs. 



Genus I' oner a Latreille. 



3. Ponera coardatu Latr. suhap. penn.sijli'anica Buchley S — Grand Chain; 



Wyandotte. 

 Rather common; nesting in the same situations as SUginaloninta pallipes. 



S U B F A M I L Y M Y H M I CI N A E 



Genus Mijnnicina Curtis. 



4. M. graininicola Latr. subsp. americuna Emery. S — Wyandotte. 

 Rare; nesting in small colonies under stones and in rotten Avood in shady 



forests. 



Genus Monomorium Maj^r. 



5. M. miniynum Buckley S 9 & — Shoals; Grand Chain. 



This minute black ant inhabits small, clustered crater nests in rather dry, 

 sandy or gravelly soil. The workers forage in files, visiting plants in search 

 of the excreta of plant-lice, the secretions of extra-lloral nectaries and dead 

 insects.
