mgs is slightly bell-sliaped. This is less apparent in the male than 
'• the female. The male measures 22-25 mm. (about one inch) 
3ross the expanded wings, and the female, 24-30 mm. 
This leaf-roller is well known in Illinois as an enemy of the apple, 
.it I have not heard of it in this State in strawberry fields; 
though we have here a very similar species, abundant enough to 
treaten* some injury, which will be next described. 
The periods of this species are such as to render it susceptible to 
le same treatment as that already found effective for the straw- 
irry leaf-roller proper,* 
The Plain Strawberry Leaf-Roller. 
(Caccecia obsoletana, Clem.)

Order Lepidoptera. Family Tortrichle. 
From collections of leaf-rollers made by an assistant in strawberry 
Ids in Union county, in Southern Illinois, last July, a number 
moths were bred which had the general appearance of the oblique- 
/nded leaf-roller ( Cacoecia rosaceana), but differed especially in the 
mi of the wings, which had scarcely a trace of the characteristic 
luosity of the front and outer margins of the latter species, and 
the obsolete character of the oblique band of the front wings, 
re reduced to two brown spots, one on the costal, and the other 
. the internal margin of the wing. 
As these leaf-rollers were scarcely less abundant in some fields 
ar Anna and Centralia than the Phoxopteris, it became a matter 
importance to understand the species and its life history, and I 
nsequently submitted a pair of them to Prof. C. H. Fernald, 
' - determination. From him I learned that the moths represented 
o nominal species, the male being Cacoecia obsoletana , and the 
nale C. transiturana , forms which however he had already sur¬ 
ged to be actually males and females of one species.! 
My larvae consisted of two lots, one collected the 9th of July, and 
e other the 81st of that month, from the same fields, near Anna, 
om each of these lots, both males and females emerged, all the 
lies having the characters of obsoletana , and all the females of 
msiturana; a fact which at once demonstrated the identity of the 
o forms. Both species were originally described and published in 
3 same work, at the same time; but as obsoletana occurs on an 
rlier page than transiturana, the former must be accepted as the 
3cific name. 
The literature of this species relates wholly to the characters and 
-ssification of the imagos.t The larva and its food plant have 
nained hitherto unknown.

.*Tyoin a remark made by Mr. Coquillett, in the article on this leaf-roller, cited above 
U,) it is clear that this species is subject to the deadly contagious disease of lepidop- 
dus larvas known as “ schlaffsucht .”
