Vol. xxvii] ENTOMOLOGICAL NEWS. 137 
During this period of years, I have taken the female from the Ist of 
July until late in September, and have handled hundreds of specimens 
in various stages of perfection and wreckage, and have in my collec- 
tion a carefully selected series illustrating different color phases. 
From my experience with the fly, I am inclined to believe that perfect, 
freshly-emerged females always have the underside of the hind wings 
and apex of fore wings of the dark blue-black color described by Mr. 
Wood, and that this speedily assumes the rusty brown as the insect 
ages, even before the upper surface shows any wear or dimness. The 
case is similar with Protoparce rustica, which, when freshly-emerged, 
has no trace of the familiar rust color, but is of a clean black and white. 
All the fresh specimens of diana in my collection, as well as my recol- 
lection and notes of other captures, indicate the correctness of the above 
idea. Some slightly worn females show in direct light the brown 
color, but held at a slight angle, and particularly in artificial light, the 
biue-black can still be seen. I have one female, nearly fresh, in which 
the outer third of hind wing, underside, which usually retains the blue- 
black, is also rusty brown, with blue-black angular dashes running to 
the outer margin. I have specimens showing the green coloring on the 
upper surface, instead of the blue; also specimens showing various 
shades of blue, and the blue area on the upper surface of hind wings 
varying from an almost complete band to isolated, blue, angular dashes.

Under the above head it is intended to note papers received at the 
Academy of Natural Sciences, of Philadelphia, pertaining to the En- 
tomology of the Americas (North and South), including Arachnida and 
Myriopoda. Articles irrelevant to American entomology will not be noted; 
but contributions to anatomy, physiology and embryology of insects, how- 
ever, whether relating to American or exotic species, will be recorded. 
The numbers in Heavy-Faced Type refer to the journals, as numbered in 
the following list, in which the papers are published. ‘ 
All continued papers, with few exceptions, are recorded only at their 
first installments. d 
The records of systematic papers are all grouped at the end of each 
Order of which they treat, and are separated from the rest by a dash. 
Unless mentioned in the title, the number of new species or forms are 
given at end of title, within brackets. ‘ ;
