of the old wood. Surely after such a piece of good fortune it 

 would disclose the imago, and tell me what it was. For three 

 years I kept that chunk of wood on my hatching box, after 

 carefully carrying it home so as to prevent jaring, and no moth 

 emerged. Finally I split it open, and after this lapse of time 

 the pupa seemed plump and clean. Its shell was granular and 

 tough, reddish in color, much like the pupa of an Alypia octo- 

 maculata, I kept it a while longer but it never disclosed the 

 imago. 



What was it ? Can anyone tell me ? I have searched the 

 same region and locality every summer since but have never 

 taken it again. 



The larva of Apatela lithospila also has the same habit of 



pupation.

On Certain Tropical Ants Introduced Into the United 



States. 

 By William Morton Wheeler. 



In a collection of Formicidse belonging to the Philadelphia 

 Academy of Natural Sciences and sent me for identification by 

 Dr. Henry Skinner, I find a number of specimens of Monomor- 

 ium destructor. This ant, originally described from India by 

 Jerdon,* though introduced into the tropics of the New World, 

 has not been recorded heretofore from the United States. The 

 specimens are labeled "Black Warrior River, Tuscaloosa 

 County, Alabama," and " Seminole Point, Monroe County, 

 Florida," collected by Mr. Clarence B. Moore. As these 

 localities are widely separated, one being at the tip of the 

 peninsula of Florida, the other in the northwestern portion of 

 Alabama, we may infer that the species has either been recently 

 introduced at different points or is already widely distributed 

 in the eastern Gulf States. That it is of comparatively recent 

 importation from the tropics there can be little doubt. 



In his original description of Atta destructor, Jerdon gives 

 the following brief account of the habits of the diminutive 

 workers : ' ' They live in holes in the ground or in walls, etc. ,
