A, Communication in reference to Arctia Nais. 
Tam in receipt of a letter from Prof. Geo. H. French, calling my attention 
to the fact that I had misquoted him in my saying that he had proved the identity 
of Arctia Nais Dru., with Arctia Phyllira Dru., and ArctiaPhalerata Harr. (Brookl. 
Bulletin. Vol. VI, p. 70). 
The remark was not intended as quotation, but a statement from memory of 
what had been accomplished by Prof. French. But | see the statement is an 
- incorrect one. One or two of my friends had for some time back been arguing 
the indentity of A. Nuis with A. Phyllira, but 1 could not agree with them though 
much was said in favor of the statement. That A. Phalerata is a variation of A. 
Nais, no one has doubted, and every one has proved that has raised the larvye. 
Taking these two facts together, and never thinking that it could be that any 
one would write to prove the identity of A. Nais and A. Phalerata, I suppose I 
cot the insects intended, interchanged in my mind; and in my statement brought 
in the name of the third. Jam sorry to have made this error. 
The synonomy given by me must be changed so that there are two species 
instead of one—the two being A. Nais Dru. and A. Phyllira Dru. 
What final determination will be made Ican not tell. Not the slightest reli- 
ance can be placed on color in the determination of species here, and I hesitate 
to say any reliance can be placed on the shape of wings. I have A. Parthenice 
Kirby (Saundersii Grt.) from the same brood with wings pointed in some and 
rounded in others on the outer margin. In the brood from A. Hxcelsa spoken of 
page 69, Vol. VI of Bulletin are in shape of wings differences as great as in A. 
Nais and A. Phyllira. Gro. D. Hutsr. 
Beetle trap. 
We owe to the kindness of Mr. J. A. Lintner, 
State Entomologist, the adjoint woodeut which 
was printed in his excellent first annual report on 
the injurious and other insects of the State of New 
York (Albany Oct. 1883). 
Mr. Lintner recommends its use to destroy 
noxious insects, but we think it would just as well 
answer to collect beetles placing it over night in the 
garden or the woods and looking next morning for 
the prey. 
It consists of a pan filled with water, diluted 
alcohol or benzine, in the middle of which is placed 
on a smooth piedestal (fruitjar) a common bright 
burning lantern, its foot being smeared over with 
an attracting stuff molasses. The cost of such an 
arrangement would be so inconsiderable that several 
lanterns might be used. F. G. SCHAUPP. -
