THE CANADIAN ENTOMOLOGIST. 26 



casionally taken flying in summer and autumn, as are so many of the 

 Staphylinidcz. 



Philonthtis apicalis Say. This is a very fine species, of a shining 

 black with the tip of the abdomen dark reddish. Two specimens aHghted 

 on my clothes in the woods 19th Oct., 18S4; and while endeavoring to 

 capture one, it emitted on my fingers a clear liquid having a strong smell 

 which I cannot describe better than by saying that it was like a mixture of 

 wintergreen and fungus essence. The odor lasted for some time, but in 

 some unaccountable manner the Staphylinid disappeared. An hour or so 

 afterward, in another part of the woods, a second specimen alighted on me, 

 and this time I was more successful and captured it. It emitted the very 

 same scent, and in this specimen it seemed to me that the scent was in the 

 form of an essence or oil all over the body ; as I could not find that the 

 insect emitted it visibly, yet my fingers would be touched with it wherever 

 I touched the insect. It was probably emitted as a clear liquid at first 

 from the extremity of the abdomen, and afterward got over the body. 



Xantholiiius cephalus Say. This specimen I have elsewhere given as 

 taken in one instance under the bark of a dead trunk of basswood in Oct. 



Cryptohium hicolor OtXTSs. One taken on my clothes 2nd Oct., and 

 another under a stone 8th Oct., 1884. 



Paederus littorarms Grav. This species I have taken in colonies in 

 passages under the bark of dead stumps in Feb., and under dry rotten 

 wood in Oct. 



Boletobius exoletus Er. This is the other species kindly determined 

 for me by M. Fauvel. It does not seem to be given in our lists. M. 

 Fauvel writes me : " Le No. 2 est BoUtobius exoletus Er. (trinotatus 

 Horn nee Er./' It is given in Fowler and Matthews' Cat. of Brit. 

 Coleopt. (as is also trinotatus Er.), and is consequently found in England. 

 I took one specimen of this very pretty species 26th Aug., 1885, in a 

 decaying " toad-stool " fungus. 



Olophrum obtectum Er. The nomenclature of the U. S. species of 

 this genus was formerly very mixed, but is straightened out satisfactorily 

 now ; marginatum Makl. is now a synonym of marginatum Kirby, and 

 convexicolle Lee. of rotundicoUc Sahib., wliile rotujidicolle Say and 

 emarginaium Say are synonyms of obtectum Er., the name now adopted 

 for the species under consideration. Two specimens were taken 8th Oct., 

 1884, in the decaying pieces of fungus with Falagria. 



I might mention that all the above genera are found in Europe^ all
