was issued, are found in wet moss and under stones near water courses, 

 thus showing great diversity of habit in insects placed in the same genus. 



Anchylarthron cornutwn £ (inornatum % ) Brend. Gregarious with 

 ants. Mississippi Valley and South Carolina. (Tr., 14, 208.) 



Trimium puncticolle Lee. Many specimens of this species were 

 taken in an ants' nest by Dr. Horn in Arizonia. (Proc. Am. Phil. Soc, 



17. 384-) 



Homalota. An undescribed species was taken with Formica rufa at 

 Bedford, Pa., by Dr. Leconte. (Tr., 6, 288.) 



Lomechusa cava Lee. About fifty specimens were taken with a colony 

 of black ants [Formica Pennsylvanica\ inhabiting a white oak log. 

 Massachusetts. (Bui. Brook. Ent. Soc, 2, 4.) Dr. Leconte took it from 

 the mounds of Formica rufa in the Alleghany Mountains ; it occurred 

 with yellow ants in Columbia County, Pa., Michigan and Maryland ; and 

 in Illinois in large numbers in the nests of Formica rufa (?). (Tr., 6, 

 287.) 



Oxypoda. A species occurred with Formica rufa at Bedford, Pa. 

 Leconte. (Tr., 6, 288.) 



Lept acinus longicollis Lee. Occurs in the middle States, and usually 

 in ants' nests. (N. S., p. 41.) 



Eleusis pallidus Lee. Ants' nests, Lancaster County, Pa. (Leconte 

 in New Species, p. 58. This insect is gregarious. I have twice taken a 

 colony early in July under the bark of Balm of Gilead stumps (Populus 

 candicans) — once with very small brown ants, and once alone. The 

 association of this species with ants appears to me to be merely acci- 

 dental. (Can. Ent., 18, 27.) 



Hister plariipes Lee. Occurs, according to Dr. Horn, from Massachu- 

 setts to Georgia. Here, I took once five specimens in April in a nest of 

 Formica herculanea. 



H. perpunctatus Lee. Mr. F. Blanchard takes this species at Tyngs- 

 borough, Mass., with a brown ant, 4.5 mm. long. (Tr., 8, 190.) 



H. repletus Lee. This, according to Mr. Blanchard, is also found in 

 Massachusetts in the nest of a small black ant. (Ent. Am., 3, 86.) It is 

 quite probable H. subopacus is also a Myrmophile. It occurs in 

 Nebraska, Colorado, and also in Vancouver Island.
