Aug. 25th, '96. On the 25th of July, '89, I found in another locality 

 quite near the University some ant-tents built over Kermes on an 

 oak sapling. This was growing in a dry place several rods from one 

 of our streams." 



Mr. E. Daecke has loaned me a fine carton tent of C. lineolata 

 which he found October 23, 1903, near Hammonton, New Jersey. 

 It is reproduced, nearly twice the natural size, in Fig. 2, PI. III. 

 Mr. Daecke writes me that "it was found about four feet from the 

 ground on swamp huckleberry alongside of a wagon road. The spot, 

 located in the typical pine-barrens, was rather moist on account of 

 a small spring in the neighborhood." 



Another tent of the carton type, but in a very dilapidated con- 

 dition, was received from Mr. A. M. Ferguson, who found it near 

 Columbia, Missouri, during the summer of 1903. This specimen, 

 like the one mentioned by Professor Comstock, was built over some 

 Kermes on an oak twig. 



In the preceding paragraphs I have taken pains to bring together 

 the scattered observations of previous authors for the reason that 

 even in localities where C. lineolata abounds, it rarely constructs 

 tents over the aphides and coccids. These structures are of local 

 and sporadic occurrence, as if owing their origin to some unusual con- 

 dition in the environment rather than to the normal instincts of the 

 species. Though I have often sought for these structures, I have 

 been able to find them in only one locality. August 20 and again 

 September 5, 1905, while collecting insects in the sandy barrens about 

 Lakehurst, New Jersey, I happened upon several fine carton tents 

 built about the terminal twigs of some young pitch pines {Pinus 

 rigida). The pines were scattered over an area of about an acre in 

 a damp place that must have been a bog at some former time, as it 

 was still partly overgrown with Sphagnum, moss and studded with 

 the stumps of larger pines destroyed by a forest fire. The C. lineolata, 

 which belonged to the subspecies pilosa Pergande, were nesting in 

 some of these stumps. The tents were widely scattered and probably 

 represented the work of several colonies of ants, except in one spot 

 where as many as fourteen were found on a single small pine only 

 six feet high. At first sight they resembled the gray or whitish 

 accumulations of a twig-boring tortricid caterpillar (Retinia com- 

 siockiana Fernald) which is destructive to the pitch pines. One of 

 these accumulations with the hole from which the moth has escaped 

 is shown in Fig. i, PI. I. Closer inspection, however, shows that the 

 tents consist of a substance like coarse, pale gray blotting paper or
