ADDITIONS TO THE LISTS OF NORTH AMERICAN TERMI- 

 TOPHILOUS AND MYRMECOPHILOUS COLEOPTERA. 



By E. A. SCHWARZ. 



i TERMITOPHILOUS SPECIES. 



Platycholeus leptinoides Crotch. A number of specimens 

 were obtained by Mr. H. G. Hubbard, in July, 1891, at Lake 

 Tahoe, Cala., in a colony of Termopsis angusticoLlis within 

 the stump of a large pine tree; other specimens, found by Mr. 

 A. Koebele in California with the same host, are in the U. S. 

 National Museum. The general appearance of this remarkable 

 Silphid indicates a parasitic or inquilinous mode of life, and I 

 have no doubt that it is a true termitophilous species. 



Microcyptus testaceus Lee. A specimen was found by Mr. 

 H. Ulke near Washington, D. C., under bark of a dead pine 

 tree. No white ants were seen near by, but the tree bore evi 

 dence of having been inhabited by them. Another specimen was 

 found by myself many years ago under similar circumstances at 

 New Smyrna, Fla., in the month of June. This would seem to 

 prove that, as it is the case with myrmecophilous inquilines, at 

 least some termitophilous species do not accompany immediately 

 the termites when these are changing the location of their nests. 



What, in my list of termitophilous Coleoptera (Proc. Ent. 

 Soc. Wash., i, p. 161), I have called ''true nests" of Termes 

 flavipes is a rather misleading term, and requires some explana-
