No. 22.] HYMENOPTERA OF CONNECTICUT. 6oi 



C. herculeanus pennsylvanicus var. ferrugineus Fabricius. 



A beautiful color-variety of pennsylvanicus, with the legs, in- 

 ferior and posterior portions of the thorax, petiole, and base of 

 gaster rust-red in the female and worker phases.' Its habits are 

 very similar to those of the typical form, but it seems to be less 

 abundant and more local in its distribution. I have been unable 

 to find it in the Litchfield Hills. 



New Haven (E. J. S. M., H. L. V.) ; Orange, New Canaan 

 (W. KB.). 



C. herculeanus ligniperda var. noveboracensis Fitch. 



Nesting in old stumps and logs like the preceding, from which 

 it differs in having a smoother surface and an entirely red thorax 

 in the worker phases. 



New Hartford, Orange (W. E. B.) ; Colebrook (W. M. W.).
