1919] Wheeler — A New Paper-Making Crematogaster 109 



Pubescence much as in the typical lineolata, but the erect hairs 

 are sparser, the appressed hairs on the legs shorter. The hairs on 

 the antennal scapes, however, are longer, more abundant and 

 oblique. 



Color like that of the typical lineolata, castaneous with black 

 gaster, the latter sometimes paler at the base; antennae and legs 

 more reddish brown, with the middle portions of the femora and 

 tibiae and the tip of the last antennal joint piceous or blackish. 



Figure 1. a. Thorax and abdomen of worker Crematogaster lineolata Say; b, 

 b, C. atkinsoni sp. nov. 



Some specimens have the head and thorax more blackish, with the 

 mandibles, cheeks, clypeus, tarsi, articulations of the legs, thorax, 

 petiole, and postpetiole reddish brown or deep red. 



Described from several workers from Fort Myers, Fla. (J. W. 

 Youngs) which may be regarded as the type-locality. I possess 

 other specimens taken in the following localities in the same state: 

 Titusville (Amer. Mus. Nat. Hist.); Crescent City (Van Duzee); 

 Jacksonville (Mrs. A. T. Slosson); Paradise Key; (E, S. Snyder) 

 and Tallahassee. 



C. atkinsoni var. helveola var. nov. 



Worker. Like the typical form of the species, except in color. 

 Brownish yellow, legs slightly paler; posterior half of gaster and 

 sometimes also the upper surface of the head pale bro\vn. 



Female (dealated). Length 6.5 mm.
