lonesome Calliphora vomitoria cavorting on my window pane. I 
noticed also Pyrameis atalanta in my garden. Before to-day there has 
been nothing. I have thought that a winter of changeable tempera- 
ture, when we get alternate thawing and freezing, was specially de- 
structive to insects, but maybe so severe a winter as we have had, 
followed by so late a spring, has been equally unfortunate for them.—

One REASON FOR THE CHANCE oF NaAmes.—At this season when so 
much of the News is given to nomenclatorial matters it may not be out 
of place to call attention to some reasons for the change of names. 
One ot the chief reasons is, the obscure ways in which many names are 
proposed. 
As an example of the way names should not be proposed, one may look 
on page 228 (15th line fram the bottom of the page) and page 232 (19th 
line from the top of the page) of May, 1912, Entomorocica, NEws. 
Here two new generic names are proposed. They are not set off any 
more than any old specific name would be; they are not in the “con- 
tents”; and they stand a fine chance of being overlooked until some 
one has proposed another name, when they may be recalled and the lit- 
erature “upset” again, so those who favor nomina conse vanda will have 
another “example.” Of course they may be in the index, but who reads 
indices for new names? It is to be hoped that those whose fault it was 
that these names appeared in such an obscure way will read this notice; 
and that they will see that new names are set off so they can easily 
be seen by catalogers or those interested. A number of changes, in the 
generic names of sawflies. were necessary because new names were pro- 
posed or new genera described in just such obscure ways.—S. A. 
ROHWER. 
[Mr. Rohwer’s suggestions, in so far as they refer to the editorial 
side of the matter, will be adopted, although we can not excuse him 
from looking into indexes.—Eb.] 
An EXPERIMENT ON THE OVIPOSITION OF A HyMENOopTEROUS Ecc 
PaRASITE.*—While experimenting with the Hymenopterous egg para- 
site, Trichogramma minutum (pretiosa) Riley, during the summer of 
1911, | exhausted my supply of the moth eggs which this parasite at- 
tacks, and was forced to examine many plants in the field for eggs to 
serve as hosts for the adult parasites which I had on hand. For some 
reason, however, there was a temporary scarcity of moths, and no 
eggs were found. In searching for Heliothis eggs on okra plants, I 
noticed the partially solidified globules of juice which had been ex- 
uded from the fruits and stems, and the thought occurred to me to
