SPECIAL REPORT OX THE COLLECTION 
93 
almost entirely omitted in the collection. This will offer no incon¬ 
venience whatever, considering that only advanced students, and 
not beginners, will be admitted to the use of the collection. In 
some few cases the types bore on the label a name different from 
that which had been used in the description; the real name is, how¬ 
ever, always easy to trace. In some instances of this kind, but not in 
all, I added a label with the true name, without removing the label in 
the handwriting of Loew. (All labels of my own which I intro¬ 
duced in the collection are signed with my name.) In cases when 
the locality named in the description did not appear among the 
specimens on hand, I had reason to suppose that the description 
had been drawn from specimens sent in my earlier consignments, 
and that they had been replaced later by better preserved specimens 
from other localities. 
With very few exceptions, everything was left as it was found. 
At the request of Loew, I put in better order the Easypogonina 
and the genus Tipula , which, in consequence of the numerous 
additions made, were somewhat in confusion and too crowded. I 
put some order in the genus Syrphus, and also transferred the con¬ 
tents of one of the drawers, which I did not think safe, into another, 
taking care to preserve as much as possible the arrangement which 
I found. Loew told me that the Empidae had been put in older, at 
his request, by Mr. Kowarz. Wishing to reduce as much as pos¬ 
sible the number of drawers to be boxed up, I left behind the 
Tabanidae , as the collection of them contained no types and was 
insignificant in comparison with my typical collection, presented by 
me to the Museum in Cambridge, Mass. For the same reason, I 
did not take the Limnobina , as all the types will be found in my 
collection in the Museum. But in both cases I singled out a few 
species which I thought worth preserving. Besides the portion of 
the collection which had been worked up by Loew, there are whole 
families which are still in a crude condition. Nevertheless they 
show a beginning of an arrangement by Loew, and contain many 
labels and notices in his handwriting which may be useful. I 
should recommend to leave such portions of the collection un¬ 
touched, as, in that state, they may be serviceable to those who will 
in future work up any of such families.
