LIST OF MY ENTOMOLOGICAL PUBLICATIONS ETC.

sides sight-seeing, and enjoying the most pleasant society which I was fortu¬ 
nate to meet almost everywhere, I did not neglect to visit my scientific cor¬ 
respondents and to make new acquaintances: Ron dani in Parma, Bel- 
lardi in Turin, the zoologist Professor Henry Giglioli in Florence, Ur. 
R. Gestro in Genoa, Prof. Achille Costa in Naples etc. By way of 
Milan, May 26 1873, I left Italy in the direction of Bozen, and proceeded 
through Klagenfurth, Buda-Pesth, Vienna (3—15 of June), Ischl, Salzburg, 
Augsburg, Lindau, to Switzerland (June 26), where I remained, visiting the 
principal localities, through the whole of July. From Geneva (Aug. 2) I 
went to Paris (Aug. 3—10) and then by London (Aug. 10—22) to Liverpool, 
where I embarked once more for New York, landed there on Sept. 3, 1S73, 
and settled in Cambridge, Mass, for the next four years, devoting myself to the 
study of North American Diptera. Professor Louis Agassiz, who greeted 
me most cordially, was complaining already at that time of the trouble in his 
head which carried him off in December. During these years of travel, I 
did not publish any thing. In the meantime (in August 1873) I had defini¬ 
tively retired from^ip!oniatic|jhgyservice. 
Although the personal details I have thus given offer but little scientific 
interest, I have compiled them, not without some trouble, from different 
sources, and put them on record here for future reference. 
In December 1873, the long-expected third volume of the Monographs 
of North American Diptera appeared in Washington. The story of the long 
delay of this publication has been told by me in this “Record”, Chapter X, 
p. 69. (Continued on p. 215.) 
1874. 
39. Description of the larva of Pleocoma Le Conte. 
Trans. Amer. Entom. Soc. V, p. 84—87, September 1874. 
NB. Dr. Le Conte gave me this coleopterous larva, which I described at 
his request (on p. 87, line 10 from top, for real, read seul). Dr. Gerstacker 
contested the view of Le Conte on the systematic location of this insect (Stett. 
Ent. Z. 1883, p.436; translated in the periodical “Entomologica Americana” III, 
p. 202). Le Conte’s views were conclusively vindicated by Dr. Horn, in the same 
periodical, III, p. 233. 
40. A List of the Leptidae, Mydaidae and Dasypogonina of North 
America. 
Bulletin Buffalo Soc. Nat. Hist. October 1874, p. 169—187. Compare 
No. 45, below. 
Additions and Corrections, in the same Bulletin, December 1875, p. 71. 
41. Report on the Diptera collected by Lieut. W. L. Carpenter 
in Colorado during the summer 1873. 
In Dr. Hayden’s U. S. Geol. and Geogr. Survey of Colorado for 1873. 
Washington, 1874, p. 561—566.
