to suspect that there may be a completely black race of Polyergus in 
this country, and that Buckley may have been fortunate enough to find 
a virgin queen of this form. But the dimensions given by Buckley 
(0.17 inch) are certainly small for either a female Polyergus or a male 
Eciton. 
32. Ponera texana ; worker. Tex. 
This is, in all probability, a species of Leptogenys, as Emery (’94, p. 
338) suggests. It seems to be merely a variety of the species described as 
P. elongata (see No. 35). 
33. Ponera amplinoda ; worker. Tex. 
Undoubtedly a synonym of Pachycondyla harpax , Fabr., which is 
local, but by no means “rare,” as Buckley claims, throughout Central 
Texas. 
34. Ponera pennsylvanica; worker. Pa. 
Recognized by Emery (’94, p. 267) as the American form of P. 
coarctata , Latr., and retained as a subspecies (P. c subsp. pennsylvan- 
ica , Buck.). 
35. Ponera elongata ; worker. Tex. 
This is undoubtedly the same as the species which was later described 
by Mayr as Leptogenys ( Lobopelta ) septentrionalis. The type locality 
is Austin, and Buckley’s description agrees almost perfectly with the 
worker. He has even noted .the difference in the red coloration of the 
individuals of the same nest. This difference, which is very striking, 
depends, of course, on the degree of maturity. The ant is common in cer- 
tain localities about Austin. Buckley says it is “not active,” but this is 
true only during cold weather. It is to be regretted that Buckley’s spe- 
cific name must be substituted for Mayr’s, wdiich expresses the fact that 
this is the only species of Leptogenys known to occur as far north as the 
United States. 
36. Ponera ( Ectatoma ) Lincecumii; worker. Tex. 
Undoubtedly a species of Pseudomyrma, as Emery maintains (’94, 
p. 270). Of the four Texan species of this genus known to me (viz.: 
P. gracilis , flavidula , pallida , and brunea), the description would apply 
only to an immature specimen of the last, but this form is itself doubt- 
ful on account of the meagreness of F. Smith’s description; so that this 
identification would be- simply explaining the obscure by the more 
obscure. 
37. Odontomachus texana ; worker. Tex. 
Of the two species of Odontomachus known to occur in the United 
States, viz. : 0. hcematodes , L., subsp. insularis, G-uer., and 0. clarus A 
Rog., Emery (’94, p. 269) conjectures that Buckley’s species is probably 
synonymous with the former, on account of its smaller size. I believe,
