labels reading Mt. Washington, Adirondack Mts. and" one 

 other locality, which I do not recall. The point is that the 

 Mt. Washington specimens were vaccinii, one labeled "type." 

 The Adirondack specimen was my alias, formerly labeled 

 u-aurcum in American collections. The other specimen was 

 octoscripta, the four specimens representing three species. 



I may add that I have found exactly similar confusion of 

 these species wherever I have looked over collections, with 

 rare exceptions. 



That is why I ask collectors to report to me if anyone has 

 vaccinii from any locality other than the Presidential Range 

 in New Hampshire. In case anyone has such a specimen, I 

 should wish not only to hear of it, but to see it. 



It has been said of some authors that they would not be 

 able to recognize their own species if locality labels were re- 

 moved. The converse seems to be true in this group. 



In the American Museum in New York last spring I found 

 a series which I declared were mixed. I separated them into 

 angulidens and e.rcelsa. After so separating them, I exam- 

 ined the locality labels. All that I had called angulidens were 

 labeled Colorado and all the e.vcclsa bore the label Laggan. 

 Excelsa, however, was taken by myself in the White Moun- 

 tains. But if anyone has angulidens from any region out- 

 side of Colorado, I should be glad to see the specimens. Sim- 

 ilarly I would like to see sackeni from any locality other than 

 Colorado, or snowi from any locality other than New Mexico. 

 If anyone can confirm or disprove the above views, I should 

 be indebted if he will correspond with me. 



A Collecting Trip in Colombia. 



Mr. E. B. Williamson, of Bluffton, Indiana, the well-known student 

 of the Odonata, left his home on November 25 for a trip in Colombia, 

 South America, where he will devote his energies to collecting his 

 favorite insects. A card dated December 4 announced his arrival in 

 Panama, where he expected to remain until the 7th. His plan is to 

 return home in March.
