I have very little doubt but that many more species of Ants will 

 be discovered even in the Southern portion of the Peninsula, and 

 I hope myself to add others to the present list, and more especially to 

 gain additional information on their habits. If any of the readers 

 of this Journal are inclined to assist me in this undertaking and are 

 able to furnish me with any details on the economy of any species, 

 I shall be very glad to receive all information and record it in a 

 Supplement, which I will publish as soon as I can collect sufficient 

 materials ; and as there may be some difficulty in making out the 

 species, especially if the observer has no microscope, 8 or 4 spe- 

 cimens inclosed in a quill and sent by letter will suffice to deter- 

 mine if the species be one of those described here ? or a new kind*
