57. C. (C.) pylartes Wheeler var. hunteri var. nov. 



Both the major and minor workers of this form differ from the corresponding 

 phases of the typical pylartes in color, the head, thorax, petiole, antennje. legs 

 and two basal gastric segments being yellow, the head of a little deeper and 

 more reddish, the base of the gaster of a paler tint than the thorax. Tips of 

 the antennal funiculi black. First and second gastric segments with a narrow, 

 transverse, fuscous band near the posterior edge; remaining gastric segments 

 black. In some specimens, the base of the third segment is also pale yellow. 



Described from numerous specimens taken by Mr. J. S. Mitchell in 

 twigs of pecan (Hicoria pecan) at Victoria, Texas, and sent me by Dr. 

 W. D. Hunter. 



Postscript 



While this paper has been going through the press, I have had an 

 opportunity to collect additional material of Camponotus in southern 

 Arizona and California and have succeeded in finding several new forms 

 belonging to the maculatus group. Descriptions of these, with the excep- 

 tion of the following interesting subspecies, must be reserved for another 

 occasion.
