and was admitted to the bar in 1879. But the practice of law 
was not to his especial liking; and, as he himself once ex- 
pressed it, “a fly on the wall was more interesting to him than 
the case in hand.” In 1884, after a four years’ career as a 
lawyer, he bade adieu to that vocation forever, and accepted 
the appointment as Special Agent to the United States Depart- 
ment of Agriculture at Washington under the late Dr. C. V. 
Riley. In 1886 he became Assistant Curator of Entomology 
in the United States National Museum, and in the three years 
of his connection with that Institution published a number of 
excellent papers and monographic works, chief among which 
are his “Monograph of the Sphingide of America north of

the time of his death, and to which was added in 1894 the office 
of State Entomologist of New Jersey. In these three capaci-

also represent a vast amount of original research along 
economic lines. His “Contribution toward a Knowledge of 
the Mouth Parts of the Diptera” (1890) set forth views on the 
homologies of these organs quite different from those generally 
accepted. 
It. 1902 he became intensely interested in the work of the 
extermination of mosquitoes which had been prosecuted with
