LOEW AS A DIPTEROLOGIST

copy of it.” I never received anything of the kind, and in a 
letter of December 22 of the same year there is a long, confusing 
paragraph about marginal and submarginal cells, without any men¬ 
tion of the promised paper. Loew’s terminology in “ Monographs,” 
Vol. I, p. xxiv (1862), with the intercalary veins , etc., did not 
suit me at all, although he considered it as the final exposition 
of his views on the subject, and, as late as 1868 (in his “ Beschrei- 
bungen europaischer Dipteren,” Preface, p. xii), recommended it 
to his readers for fuller information. In my second monograph on 
the Limnobina (1869), I finally concluded to adopt Schiner’s view 
of the fourth vein , which did good service as a working hypothesis. 
In my paper ( Berl. Unt. Zeit., 1896, p. 287; 154, 1896), “ Notice 
on the Terms Tegida, Antitegulaf etc., I have shown that Loew had 
misused the term tegida. In this paper I said that in editing the 
first volume of the “ Monographs,” etc., I had of course no right to 
change Loew's terminology, but that I had taken the liberty, in 
the footnote of page xiv, to remark: “ Some authors call them 
squamae. — O. S.” I have also had a discussion with Loew about 
the term arista. Loew had always used the term “ Fiihlerborste ” 
(in Latin seta antennarum ), which, in Vol. I of the “ Monographs,” 
translated under his supervision, was rendered by the term anten¬ 
nal bristle (loc. cit., p. 34, 35, and passim ). This term is mislead¬ 
ing, because it suggests the idea that this organ has something in 
common with a real bristle , whereas it must be considered as a part 
of the antenna. In the following volumes of the “ Monographs,” 
translated under my supervision, I adopted therefore the term 
arista , that had been used in England. Loew objected to it: 
“ Arista has much against it ” (“ Arista hat manches gegen sich,” 
letter of April 14,1863) ; nevertheless, this time I persisted. This 
unpreparedness of Loew in matters of terminology became still 
more apparent when the Smithsonian Institution asked him to 
draw up a General Introduction to Diptera, to be placed at the 
head of the first volume of the “ Monographs.” This very natural 
request caused Loew the greatest perplexity; he accomplished the 
task, but with “ great effort,” and confessed at the same time that 
he had “ learned much during this work.” (Compare my account 
in Chapter VII, p. 47.)
