examined), at a height of about 80 to 100 ft. from the ground, were dis- 

 covered several dozens of a Lace-wing fly, Chrysopa, sp. 



The occurrence of all of these insects in so secure a resting-place 

 rnay be accounted for from the fact that the sapwood had been eaten 

 out by Borers. The woodpeckers in their search for food had punctured 

 numerous holes in the outer bark, leaving an easy entrance for these 

 small flies and moths to the dry chamber formed between the bark and 

 the shrunken stem of the tree. 



But the curious part of the whole circumstance was the relative 

 positions of the species. Few specimens of Lyonetia were seen above 15 

 feet. The Gelechiidse and Tortricids were all closely associated at greater 

 heights, and all the Chrysopas were in a comparatively small area and 

 near the top of the tree, not a single specimen being discovered in either 

 tree below the limit of 80 feet. 



The date of the above trip was March 2nd, 1905; there was about 

 two feet of snow on the ground, but a thaw having set in a i^w days 

 previously no doubt accounted for the activity of many of the specimens 

 taken. 



The woodchopper tells me that nearly a mile away from the trees 

 mentioned above, he found another tree, a dry Tamarack, with the same 

 kinds of insects beneath the bark. He brought me several specimens in a 

 cyanide bottle which I had given him. Again the Lace-wing flies, and the 

 other moths associated vvith them, were at the top of the tree. 



HYDROMETRA AUSTRALLS, Say. 



BY J. R. DE LA TORRE BUENO, NEW YORK. 



Since my "Notes on Hydrometra Martini, Kirk.," in the Canadian 



Entomologist for January of this year, pages 12 to 15, I have had the 



opportunity of examining another specimen of Say's "var. australis" and 



study of it confirms the conclusions I then drew. It is unquestionably a 

 good species and not merely a variety, and it affords me real pleasure to 

 recognize a true Hydrometra of which Say is the author. The specimen 

 to which I here refer is also a male and was taken by Mrs. Annie Trum- 

 bull Slosson, at Jacksonville, Florida. Since Say gives his locality as 

 "Louisiana" and my specimen came from Thomas ville, Georgia, the bug 

 would seem to have quite an extended range along the Gulf of Mexico 

 and on the warmer shores of the Atlantic Ocean. Lack of material, 

 especially of females, makes it unwise to draw up an extended description 

 at present, but it should be done in order to establish the species beyond 

 perad venture,
