tion, probably some variety of Pheidole dentata, Mayr., or Ph. Hyattij 
Emery, but the exact species will never be determined. A Ph. picea 
was later described from Mexico by Mayr. 
58. Atta brazoensis ; soldier, worker. Tex. 
Probably Solenopsis geminata , Fabr., according to Emery (’94, p. 
276). 
59. Atta pennsylvanica ; soldier, worker. Pa. 
This species, taken near Philadelphia, must be a Pheidole, as Emery 
(’94, p. 338) surmises. For geographical reasons, it is probably Phei- 
dole bicarinata, Mayr., or some form of Ph. vinelandica, Forel, but this 
can never be decided. 
60. Atta coloradensis ; soldier, worker. Tex. 
Specimens of Pheidole sp. mixed with Solenopsis geminata, according 
to Mayr (’86a, p. 365). 
61. (Ecodoma virginiana; worker. Va. 
It is exceedingly difficult to interpret Buckley’s description of this 
species. Emery (’94, p. 329) believes that it may refer to a Strumi- 
genys, possibly to S. clypeata, Emery, but it would agree even more 
closely with a small specimen of Atta ( Trachymyrmex ) sept&ntrionalis, 
McCook. It is certainly one of the most exasperating descriptions in 
the series. 
62. (Ecodoma texana; male, female, worker. Tex. 
This, of course, refers to Atta fervens, Say, the common “leaf-cutting 
ant” of Texas. 
63. Myrmica ( Monomarium ) molefaciens ; female, worker. Tex. 
Now known as Pogonomyrmex barbatus, Smith, var. molefaciens, 
Buckley (Emery, ’94, p. 308), the common Texan “agricultural ant.” 
64. Ecodoma pilosa; worker. Tex. 
Emery (’94, p. 330) referred this species to the group Attii, but was 
unable to give a more precise determination. It cannot refer to either 
of our species of Cyphomyrmex ( C . rimosus, Spin., and C. Wheeleri, 
Forel), nor to the form included under Buckley’s next description; so 
that we can only suspect that there is in Texas still another fungus- 
growing ant which, to .judge from Buckley’s description, must resemble 
Apterostigma or Sericomyrmex. Northern Texas, however, would seem 
to be a very improbable locality for such a form. 
65. Ecodoma tardigrada ; male; female, worker. Tex. 
Mayr, after comparing some of Forel’s specimens of Atta ( Trachy- 
myrmex ) i septentrionalis , McCook, with a type of Buckley’s A. tardi- 
grada in his possession, pronounced the species to be the same, so that 
Forel (’84) and subsequent writers have relegated McCook’s specific
