THE HABITAT OF DORU AGULEATUM SCUDDER. 



BY A. N. CAUDELL. 



On October 3, of the present year a number of specimens of 

 the above insect were taken by Mr. McAtee near Great Falls, 

 Virginia. This record is deemed worthy of publication as this 

 is the first time this earwig has been taken within the bounds 

 of our local fauna. In addition to the several specimens repre- 

 senting both sexes taken on the above date there was a single 

 immature specimen taken at the same spot on August llth of 

 last year, also by Mr. McAtee. 



The exact point of capture of the above material is a small 

 swamp near the Virginia shore of the Potomac River about one 

 mile below Great Falls, some twelve or fifteen miles from Wash- 

 ington. The earwigs occurred on a sedge-like plant growing in 

 the swamp, a situation to require wading to secure specimens. 

 Careful search under bark, beneath chunks, etc., near this vicin- 

 ity failed to turn up additional material, those specimens swept 

 from the above mentioned sedge-like plants growing in the swamp 

 being the only ones secured. 



TWO NEW SPECIES OF LACE-BUGS. 



(Heleroptera: Tingidae) 

 BY OTTO HEIDEMANN. 



INTRODUCTORY STATEMENT. 



This posthumous article has been prepared for publication by 

 the undersigned. Through the kindness of Dr. L. O. Howard, 

 Mr. Heidemann's notes on Tingidae, his favorite family, were 

 turned over to the writer to determine what material among them 

 was suitable for publication. It is with regret that the report 

 is made that description of but one undescribed species was found, 

 and a nearly finished illustration of a second new species. These 

 new species are herewith presented. It was Mr. Heidemann's 

 plan to monograph the American Tingidae, and he did have a 

 very thorough knowledge of them. Apparently, however, very 

 little of this fund of information was committed to writing. Mr. 

 Heidemann was wholly unselfish and spent so much of his time 

 helping others, that his own work, even that which lay nearest 

 his heart, was neglected and postponed, until, as it turned out, 

 it was forever too late. If the writer may be allowed to record a 

 personal tribute to Mr. Heidemann, he would say that none was 

 ever more generous, with time, advice and assistance, to fellow-
