110 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



Short trips to Cresson Springs, Pennsylvania, to Piny 

 Point, Maryland, to Mountain Lake, Virginia, and in later 

 to his summer home at Pen Mar, Maryland, in the Blue Ridge, 

 interrupted his otherwise permanent stay in Washington. In 

 the early years of the Smithsonian Institution there was no 

 public collection of insects in Washington, and Ulke, being 

 interested in the subject, and associated with the scientific 

 men, received the insects collected on the numerous Govern- 

 ment explorations of the West. The insects of the West 

 were then but little known, so that these specimens greatly 

 enhanced the value of Ulke's collection. It was from one of 

 these trips that he received four specimens of Amblycheihi, 

 unknown since described by Say; one of the four finally 

 reached the cabinet of Dr. C. A. Dohrn, in Stettin. 



Ulke was a most diligent correspondent, and exchanged 

 beetles with nearly every entomologist of prominence in this 

 country from 1865 to 1890. Among his papers were found a 

 list of his correspondents about 100 in the United States. 

 This list included John Xanthus, Rob. Kennicott, Dr. J. L. 

 Leconte, M. C. Fay, Ferdinand Fuchs, Dr. G. M. Levette, A. 

 S. Fuller, G. D. Smith, Johnson Pettit, James Behrens, E. 

 P. Austin, Dr. E. Brendel, and Belfrage, Boll, Linthicum, 

 and Wadgymar of Texas. He named material sent in by col- 

 lectors, and thus obtained a wide reputation; the beetles fig- 

 ured by Townend Glover in his "Manuscript Notes" were 

 named by Ulke. He was the first in this country to realize the 

 need of a long series of specimens; and with his uniformity of 

 mounting, a block of one species placed by the side of an allied 

 species could be seen to differ at a glance. 



Gradually he amassed one of the largest, most beautifully 

 prepared, and best named collection of beetles in America. 

 The number of Leconte types contained in Ulke's collection is 

 indicated in Henshaw's Bibliography of Dr. Leconte. Besides 

 these there are some types of Dr. Horn and Dr. Dietz. 



He took little interest in exotic Coleoptera, and had only a 

 few from Europe and Central America. 



The death of his wife in 1893, greatly depressed him; he
