I 
“When compared with other closely allied and resembling species, 
this little moth may be characterized in the following manner: 
The ground color of the front wing is decidedly bright and pale; . 
the discal spots are almost always confluent, thus forming an ab¬ 
breviated transverse bar; the dark markings are well defined, and 
the triangular dark costal spot starting from the inner third of 
the wing is distinctly relieved, while the ‘brick-red’ ( nearer a cin¬ 
namon-brown) triangular spot which opposes it is large, so that 
the space it occupies on the inner margin is nearly as wide (gen¬ 
erally within one third) as that between it and the transverse 
posterior line. The lower half of the basal space is often of a 
distinct cinnamon-brown, and an oblique dusky band, which Mr. 
Walsh has not mentioned, is often quite distinct, running from 
near the apex to the brown triangle, where it connects with the 
inner margin.”* 
DISTRIBUTION. 
This insect seems to be very generally distributed throughout 
Illinois and adjacent states. During the past season I have found 
it more or less abundant in the following counties of this State: 
Champaign, Crawford, Edwards, Effingham, Jackson, Marion, Mad¬ 
ison, McHenry, McLean, Monroe, Montgomery, Perry, Randolph, 
Shelby, Stephenson, St. Clair, Union, and Wabash. In 1885 Pro¬ 
fessor Gar man found it common in orchards at Mt. Pulaski, in 
Logan county, and the year previous the larvae were collected at 
Du Quoin, in Perry county. 
In the states adjacent to Illinois this pest seems to have a wide 
distribution. In the article from the Fourth Report of the State 
Entomologist of Missouri, quoted above, Dr. Riley writes that it 
“occurs throughout our own State and is quite injurious in the 
southwestern counties.” In Tennessee, as I am informed by 
Mr. E. W. Doran, Entomologist to the Board of Agriculture of 
that State, it is “plentiful in most orchards” that he has examined; 
and Prof. P. H. Snow, of Lawrence, Kansas, writes that it is 
quite a common nuisance in his state. In Iowa it has long been 
known, though Prof. Herbert Osborn, of Ames, informs me in a 
recent letter^ that it “seems much less abundant than in the past.” 
He adds: “While a common pest, it has never, to my knowledge, 
caused any widespread destruction in this State.” 
In the writings of Walsh and others, noted above under the head 
of Literature, it is stated that the species did not at that time 
occur either in Southern Illinois or New England. It seems, 
however, to have spread rapidly since, for it is now common in 
the first-named region, and, as I am informed by Prof. C. H. 
Fernald, occurs throughout New England. Is it not possible that 
it was merely overlooked twenty years ago?
