metis were very pale pink, others light reddish pink. One 

 specimen was wholly dull olive green, with the usual black 

 markings, but a well-marked color variety, nevertheless. 



21. The Threatening Attitude of a Staphylinid (Coleop.). 

 While camped at Mountain Lake, Virginia, July 26, 1902, 



a large species of this family was noticed in a sandy road lead- 

 ing down the mountain; the abdomen was curled over its 

 back as usual. It was walking rapidly and concealed itself 

 under a piece of wood when I approached. Upon moving the 

 hand toward it, the abdomen was suddenly darted out as if 

 to sting ; upon closer approach of the hand, the movement was 

 more rapidly repeated and a white forked process suddenly 

 projected from the anus at each movement. The insect was 

 harmless. 



22. The Host of Anagrus spiritus Girault (Hymen.). 



Late in March, 1912, I received for identification from Mr. 

 R. L. Webster, Iowa State College of Agriculture and Mechanic 

 Arts, five slides bearing specimens of this species, all labelled 

 "From egg of Empoasca flavescens, Ames, Io\va, R. L. W.," 

 and respectively, "Exp. 234. 26 July, 1911," bearing i $ , I 9 ; 

 "Exp. 208, 12 July, 1911," bearing i$ ; "Exp. 235, 27 July, 

 1911," i $ , i 9 ; "Exp. 207, 22 July, 1911," bearing I $ , and 

 "Exp. 233, 26 July, 1911," i $ ; a total of 5 $ 's, 2 $ 's. 



I have noticed a mistake in the original description of this 

 species (Entomological News, XXII, May, 1911, pp. 208-209), 

 where it is stated "that the sixth funicle joint is barely long- 

 er than the first (p. 208, next to the last and last line) : the 

 second funicle joint was intended instead of the first ; more, 

 the second joint is slightly longer than the first. In the next 

 sentence (running over to the first line of p. 209) we read 

 "whereas in incarnatus it is distinctly longer than the first 

 funicle joint by at least a fourth," the it referring to the sixth 

 funicle joint, again the first funicle joint should have 

 read the second. The identification of these specimens was not 

 easy and with certainty may have been impossible were it not 

 for the fact that I had specimens of its closest ally, arumtus
