or soldiers seem to be no more vicious than the small and intermediate 

 forms. Smaller nests contain very few or none of the big-headed 

 individuals, which naturally increase in number with the growth of 

 the colony. 



Leptothorax Mayr. 



^T,. L. longispinosus Roger. — This species is recorded from New 

 Jersey by Emery. I have taken it in the woods about Fort Lee. It 

 nests under small stones lying on large boulders, in the clefts of rocks, 

 in stone walls, and more rarely under bark. It seeks its food on the 

 low vegetation in the shade of the trees. 



34. L. curvispinosus Mayr. — - Clementon (Viereck) ; Riverton 

 (Viereck) ; Lakehurst (Wheeler and Davis) ; Fort Lee (Wheeler) . 



This species usually nests in hollow twigs of the elder in shady 

 woods. Two fine colonies were found at Lakehurst in oak-galls 

 (Amphibolips ilicifolicB Bassett and A. confiuentus Harr.). 



35. L. schaumi Roger. — -There can belittle doubt that this species 

 occurs in New Jersey as it is known to occur in Pennsylvania and has 

 been found near New York City. I have seen it nesting in the bark 

 of large elms and willows. 



36. L. fortinodis Mayr. — A small colony of this species was found 

 at Lakehurst nesting in the bark of a living pitch-pine (Pinus rigida) . 



37. L. texanus davisi subsp. nov. 



The worker of this form differs from that of the typical texanus, 

 all three phases of which I described from Milano, Texas, 1 in the 

 much less rugose surface of the head, thorax, and pedicel. This is 

 especially noticeable on the thoracic dorsum, petiole, and postpetiole, 

 where, instead of the deep reticulate rugosity of the typical form, the 

 surface is finely and evenly reticulate and therefore much more shining. 

 Corresponding differences are observable between the females of the 

 two forms. The female davisi has the upper surfaces of the petiole 

 and postpetiole shining though rugose. The epinotal spines are also 

 longer and more robust than in the typical texanus. 



Described from several workers and a dealated female taken at 

 Lakehurst. Like the Texan form, davisi nests in pure white sand, 

 forming slender galleries a few inches in length. It moves about 

 rather slowly on the sunlit surface of the sand in search of small 

 insects.
