No. 425.] THE TEXAN LEGIONARY ANTS. 367 
The Californian A. debilis Lec. has been recorded from Texas 
by Schwarz, but the species here described differs in having the 
elytra serrate near the humeri. The original three-line descrip- 
tion of A. debilis Lec! would not serve for identification, but 
Horn? mentions that the elytra have the “ margin not serrate.”

2. Ecitonidia wheeleri Wasmann.’ 
A second specimen of this species was found April 20, 1901, 
in a nest of Eciton schmitti Em., the same species with which 
the type specimen was discovered. It is nearly as large as the 
worker ants and quite similar in color and movements, so that it 
is rather difficult to distinguish among a large number of ants. 
It is undoubtedly mimetic of the ants, but whether its resem- 
blance enables it to deceive the ants as to its identity would 
seem very doubtful. The probability of its resemblance being 
due to some outside influence of natural selection is heightened 
by the fact that it must be exposed to insectivorous animals as 
it marches along in the columns of the ants, which are often seen 
in broad daylight and hence are exposed more than most species 
of ants with their attendant myrmecophiles. 
3. Ecitopora tenella Wasmann.* 
The original types of this species were part of a collection of 
numerous specimens from a nest of Eciton schmitti collected 
during October at Austin. Since that time we have found 
another species of this genus, the second to be recorded from 
North America.
