one of his first visits to Uhler, probably in 1880. It was al- 

 ready at that early date a very large manuscript book, but it 

 has never been published, owing to his desire to make it as 

 nearly perfect as possible. When he became sure that his 

 eyes had finally failed, he consulted with Mr. O. Heidemann, 

 of the Bureau of Entomology at Washington, concerning the 

 possible completion of the work by Mr. Heidemann, but no 

 definite arrangements were ever made. In 1907 he finally 

 decided to part with his collections, and presented the Meyer- 

 Dur collection of European Hemiptera to the Museum of Com- 

 parative Zoology at Cambridge. The rest of his collection, in- 

 cluding all of the North American Hemiptera, was presented

 Washington in installments by Mr. Heidemann and Mr. H. 

 S. Barber. It is now a part of the National Museum collection. 



At one time Doctor Uhler was officially known as the Ento-

 of the Peabody Library he was given leave of absence to ac- 

 company a survey party on an expedition to Colorado. In 

 Baltimore he was at an early date energetic in his endeavors

 of Maryland, and delivered addresses on scientific subjects 

 throughout the State. He always took the keenest interest in 

 the Maryland Academy of Sciences, of which he was Curator, 

 Secretary, Vice-President and later President. In 1900 he was 

 given the honorary degree of LL.D. from New York Uni- 

 versity, and in 1912 he was made an honorary member of the 

 International Congress of Entomology at Oxford. 



Doctor Uhler was one of the founders of the Entomological 

 Society of Washington, and used from time to time to come 

 to Washington for the evening meetings of the Society, al- 

 ways having some interesting topic to present. He was a 

 fluent and delightful speaker with a charming personality, and 

 inspired interest in the most technical subject by his lucid 

 method of presentation. On several occasions also he enter- 

 tained the Society at his home in Baltimore, so that Washing- 

 ton entomologists had the great privilege of personal friend-
