en WHEELER — TWO NEW ANTS 35 
tinctly smoother and more shining, and the foveole are smaller 
and sparser on the head, thorax and pedicel. In the worker 
wheeleri (fig. 2, d), besides the structural differences shown in the 
figures, the mesoépinotal suture is seen to be obsolete, the expanded 
frontal carine are larger, thinner and whitish yellow, and the an- 
tenn, knees, tibis: and tarsi are red. The foveole of the head 
have appressed silvery hairs like those on the thorax and pedicel, 
and the erect hairs are much longer and more conspicuous than in 
the worker rohwert. 
Besides C’. rohweri only two species of Cryptocerus are known to 
cross the southern boundary of the United States, C. varians F. 
Smith, which occurs on the southern tip of Florida, and C. texanus, 
recently described by Santschi from Texas, without precise locality. 
Of this form I have long had specimens taken by Mr. Charles 
Schaeffer at Brownsville, Texas, but I referred them to C. angulosus 
Mayr, under which name they are cited in my ant book.
