The types of this form were, in all probability, collected by Buckley in 

 central Texas, where it is rather common, nesting nnder stones in dry 

 woods. Emery's specimens also came from this region and from Lou- 

 isiana. I have before me specimens from the following localities : 



Texas: Austin, topotypes (Wheeler) ; Marble Falls (Wheeler) ; Hand- 

 ley (J. C. Crawford) ; Leary (W. D. Pierce). 



'New Mexico: Pecos (T. D. A. Cockerell and M. Grabham). 



Arizona: Prescott (Wheeler). 



Colorado: Manitou (Wheeler). 



Although Emery records sansdbeanus as a variety of maccooTci, I be- 

 lieve that it should rank as an independent subspecies of maculdtus, on 

 account of its smaller size and the different proportions of the head, body 

 and legs in the worker major. 



10. C. maculatus sansabeanus var. torrefactus var. nov. 



The worker major differs from that of sausaheanus in having the whole 

 gaster brownish yellow, like the thorax, petiole and legs. The head is deep 

 red, with the front and vertex black and the posterior corners each with a 

 yellow spot ; in the worker minor the head and antennse are brown, the 

 mandibles darker. The antennal scapes in all the workers are less dilated at 

 the base than in the corresponding phases of sansabeanus. The male has the 

 funiculi, tarsi and tibiae paler, the pleurae and often the thoracic dorsum and 

 gaster piceous instead of black. The head is very broad, with shorter and less 

 concave cheeks than in the preceding subspecies and varieties, and the anterior 

 portion of the head is conspicuously hairy. The wings are scarcely suffused 

 with yellow, the veins and stigma very pale. I have not seen the female. 



Described from numerous workers and males from three colonies, two 

 taken by myself in the Coconino Forest and Indian Garden, Grand 

 Canyon, Arizona, the other by Mr. E. Y. Chamberlin at East Mill Creek, 

 Utah. 



11. C. maculatus bulimosus subsp. nov. 



Worker major. Length, 9-11 mm. ; head, 3.2 x 3.2 mm. ; scape, 2 mm. ; hind 

 tibia, 2.5 mm. 



With the stature of sansabeanus, but differing in the following particulars: 

 head proportionally larger, as broad as long, with the anterior angles larger 

 and more inflated as in C. herculeanus, so that the mandibles appear to be 

 more retracted. Clypeus even less produced, with the median border crenate 

 and slightly pointed in the middle and the carina more distinct. Antennal 

 scapes shorter and much more flattened and dilated at the base, with a small 

 lobe as in maccooki, and nearly as broad at the tip as at the base. Thorax 

 thickset, with high, rounded epinotum, the declivity being as long as the base. 



Body sul)opaque ; mandibles, legs and venter more shining ; surface of head 

 and thorax rather coarsely, gaster more finely and superficially shagreened. 

 "Whole head, including the clypeus and front, covered with small punctures.
