LIST OF MY ENTOMOLOGICAL PUBLICATIONS ETC. 
61. Catalogue of the described Diptera of North America. 
Second Edition. Washington, Smithsonian Institution, 1878, p. XLVIII 
and 276. 
NB. Professor Spencer F. Baird published a detailed Notice about this 
second edition in the Smithsonian Report of 1878, p. 17—18. To charac¬ 
terize the difference between it and the first edition, he said: “This new edition 
is not merely a revision of the Catalogue published twenty years ago, but it is 
an entirely new one, prepared on a different plan. The difference between eleven 
and sixty-six, the number of species of the one genus Trypeta, represents the 
addition made to our knowledge during the interval between the two Cata¬ 
logues” etc.
