Notes on Ant Behavior 213 
July 25, 1930. Many winged ants of this species seen about 
the yard and house during two days. 
July 24, 1932. Several winged ants seen about vegetation 
and one trapped on screened porch. 
The ants were submitted to Mr. M. R. Smith for identifica- 
tion, and he also found the specimens infected with the parasitic 
fungus, Laboulbenia formicarium Thaxter. Mr. Smith writes 
that although he has noted the fungus on other species of ants 
it is by no means a common thing to find it on Formica fusca 
var. subsericea.* 
It was noted that these ants were very attentive to tree hop- 
pers. A blue written’ thistle plant in the garden harbored on 
the underside of its leaves many adult as well as immature tree 
hoppers identified ey ‘Mc P. W. Oman as Entylia concisa 
Walk. There were from four to ee tree hoppers on each 
ou 
rag weed plant growing in a shady place but in this case the 
hopper was identified by Mr. F . W: Oman, as nymphs and 
adults of Publilia concava Say. 
Eciton schmitti [M. R. Smith] 
Some years ago at dusk I discovered a colony of this ant on 
a maurading expedition at Wickes, Mo. At that time (See 
Trans. Acad. Sci. St. Louis 24:41, 1922.) Dr. Wheeler wrote 
that the northern limit of this species is Doniphan, Mo., which 
is near the Arkansas border. On May 30, 1931, at Ranken, Mo., 
about 23 miles northwest of the Wickes region I found two 
strong colonies in two fallen cart oak logs ; these logs were 
some distance apart. There a big-bodied queen in each 
colony surrounded by several aainok of clustering workers. 
y hung on to one another in deep masses just as I have seen 
a sister species of Ecition do in Panam
