Buckley’s North American Formicidae.

the size of the head was probably due to confounding several species. 
This could be done very readily by a superficial collector, as there are 
about a dozen species of Pheidole in the neighborhood of Austin, and 
some of these are very common. The female described by Buckley is cer- 
tainly not the female of instabilis ; as the latter has a very characteristic 
coloration quite unlike that of any other Texan species known to me. 
Again, some of the ethological remarks must refer to Solenopsis gemi- 
nata , as, e. g., when he describes the ants as “throwing the excavated 
earth without order over the surface.” 
43. Myrmica ( Monomarium ) minima ; female, worker. Tex. 
There can be no doubt, as Emery has shown (’94, p. 274), that this 
is merely a variety of Monomarium minutum , now known as M. m., var. 
minimum , Buckley. 
44. Myrmica ( Monomarium ) cceca; worker. Tex. 
Emery (’94, p. 260) suggests that this is probably an Eciton. It may 
be either E. opacithorax , Emery, or E. Schmitti , Emery, but the descrip- 
tion is too vague to be intelligible. 
45. Myrmica ( Monomarium ) marylandica; worker. D. C. ; Md. 
Very probably some form of Cremastog aster lineolata, Say, as Emery 
maintains (’94, p. 286). This is shown by the locality and by Buckley’s 
remark, “it often carries its abdomen turned up erect.” 
46. Myrmica ( Monomarium ) montana; worker. Tex. 
This is probably the small agricultural ant which I have described as 
Pogonomyrmex imberbiculus (’02). The description agrees equally 
well, however, with Xiphomyrmex spinosus, Pergande, which is often 
found in the same localities, though the latter does not, as a rule, live 
under stones. I am certain that Buckley’s rather vague account must 
refer to one or the other of these two species. 
47. Myrmica ( Monomarium ) lineolata; female, worker. 
Another unintelligible description, probably referring, as Emery sug- 
gests (’94, p. 338), to some species of Myrmica. The omission of any 
mention of locality renders it utterly worthless. 
48. Myrmica ( Monomarium ) columbiana; female, worker. D. C. 
This is obviously a Cremastog aster, but it can not be 0. lineolata , 
subsp. Iceviuscula, Mayr, as Emery suggests, since the queen of this sub- 
species has a red head and thorax and the latter merely striped with 
black, whereas in the female of Buckley’s form the head and thorax are 
black. It must be some other form of lineolata , possibly var. cerasi , 
Emery. 
49. Myrmica ( Monomarium ) aquia; female, worker. Va. ; N. Y. 
This is treated by Emery (’94, p. 304) for good reasons as a subspe-
