94 PROC. ENT. SOC. WASH., VOL. 23, NO. 4, APRIL, 1921 



United States," published as an Entomological Bulletin in 1902. 

 Many of these illustrations have been widely copied and repro- 

 duced throughout the entomological literature of the world, and 

 particularly those illustrations relating to medical entomology, 

 such as the mosquitoes, the house flies, the roaches, etc. An 

 amusing anecdote regarding Miss Sullivan is told by Dr. F. H. 

 Chittenden, under whose direction Miss Sullivan worked at 

 various times. Miss Sullivan came to him one day with a very 

 troubled expression on her face, and asked the following ques- 

 tion: "Doctor, what is to become of me after I have drawn all 

 of the insects that are of economic importance?" 



I have been unable to find that any notice of Miss Sullivan's 

 death was published in any of the entomological periodicals of 

 the time, but the records of the Department show that her ser- 

 vices terminated on June 26, 1903, and as she died very suddenly 

 it is probable that her death occurred about that date. It is 

 needless to say that poor Miss Sullivan's worry over the narrow- 

 ing field of illustrative work was groundless and that although 

 thousands of drawings of insects have been made since her day, 

 the limits of such work are still enshrouded in the mists of the 

 dim and distant future. Mr. H. G. Hubbard, whose bulletin 

 on the Orange Insects was one of the most popular publications 

 ever issued by the old Division of Entomology, was a very good 

 and painstaking draftsman. He made the drawings for plate 

 XIV of that publication and also the single plate accompanying 

 Hubbard and Schwarz' list of "The Coleoptera of Michigan." 



The engraver who cut many of the blocks for illustrations in 

 the various reports and bulletins of the olci Division of Ento- 

 mology was Otto Heidemann, who afterwards developed into 

 one of the foremost authorities on the Hemiptera in this country. 

 Mr. Heidemann was born in Magdeberg, Germany, September 

 1, 1842, and died at Washington, D. C., November 17, 1916. 

 He learned the art of wood engraving in Leipzig and practiced 

 his profession in southern Germany for about three years before 

 coming to this country. Mr. Heidemann arrived in Washing- 

 ton some time during 1876 and was employed shortly afterward 

 in making illustrations for government publications. In 1880 

 he was employed as a topographical draughtsman with Wheeler's 

 Geographical Survey and in 1883 was appointed engraver for 

 the Department of Agriculture. He remained in this capacity 

 for about 12 years or until the development of commercial 

 photography completely revolutionized the methods of illustra- 

 tion, when he took up the study of insects and became a very 

 successful specialist in the order Hemiptera. While Mr. Heide- 

 mann's art work in connection with entomology consisted mainly 

 of engraving the drawings made by George Marx, Miss Sullivan 

 and others, he was a good draughtsman and made quite a number 

 of entomological drawings, some of which were published, but
