their early stages, life histories and habits. In the early years 

 at Philadelphia he did much with the Odonata, as a paper 

 in the News for January, 1903, indicates, a notable discovery 

 of his in this order being that of Tclagrion? daeckii at 

 Manumuskin ; nor did he ever neglect them, as a note in our 

 issue for last July (page 278) evidences. Later the Tabanidae 

 especially attracted his energies and he prepared the list of 

 species of this family for the 1909 report on the Insects of 

 New Jersey. In this report. Prof. John B. Smith wrote of 

 him : *'An excellent general collector whose expeditions into 

 South Jersey have produced a large number of most useful 

 records in almost all orders." Many of his associates are 

 indebted to him for valuable material and he unquestionably 

 did much in the way of accumulating positive data on geo- 

 graphical distribution. The writer especially will greatly miss 

 his kindly aid extending over nearly twenty years. 



His nephew, Mr. Erich E. Lehsten, of New York City, 

 writes of him: "Mr. Daecke was always exceedingly self- 

 contained ; very rarely discussing his private affairs with any- 

 one ; doing all the good he could ; giving those with whom he 

 came in contact every assistance in his power, and, to the best 

 of mv knowledge, has never injured anyone." He never mar- 

 ried, but was a great lover of children. 



He contributed the following papers to the News. To bring 

 together his collecting records contained in volumes XI-XXIX 

 is a task of some considerable extent which, we believe, has 

 not been attempted.
