lonesome Calliphora voniiloria cavorting on my window pane, 

 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 CHANGE OF NAMES. 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 of 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 (i5th line frqm the bottom of the page) and page 232 (igth 

 line from the top of the page) of May, 1912, ENTOMOLOGICAL 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. ED.] 



AN EXPERIMENT ON THE OVIPOSITION of A HYMENOPTEROUS EGG 

 PARASITE.* While experimenting with the Hymenopterous egg para- 

 site, Trichograiniua minutuin (pretiosa) Riley, during the summer of 

 1911, I 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
