The Lesser Apple Leaf-Folder. 
. 
(Teras malivorana, Le Baron.) 
Order Lepidoptera. Family Tortricid,e. 
i species, originally described by Dr. Le Baron in his first 
, and again by Dr. Thomas in the seventh of the series from 
>ffice, has not been reported as especially injurious since its 
il discovery, in 1870. Late in June of this year the attention 
proprietors of the Home Nursery at Normal was attracted by 
asted and withered look of many of their young apple trees, 
ury which assumed alarming proportions before the middle 
y. On investigation, this proved to be largely due to the above 
eaf-roller, which had nearly attained its growth, and was already 
erming to the pupa. These larvae evidently represented the 
l brood, as indicated by Le Baron’s dates, and our breeding 
j show the existence of a third brood also. Of specimens 
ed July 5, the first pupa was observed on the 17th, and the 
loth appeared August 7, the brood continuing to emerge fora 
iys thereafter; and a number of full-grown larvae, collected in 
jiilia on the 6th of August, emerged on the 20th. 
species has been noted for its apparent subjection to some 
ctive influence which has the effect to reduce it speedily to 
ificance; whether parasitic attack or susceptibility to weather, 
it been known. From the specimens reared by us, a single 
lopterous parasite emerged on the 24th of July, which belonged 
genus Hemiteles, and apparently to a species undescribed, 
was a male, and no other examples were obtained, I have not 
it it best to give it a specific name. 
'Iteles, sp.— The head and the body are black, except the 
ir two-thirds of the abdomen beneath, which is yellow. The 
ftsal joints of the antennae are white in front, and the three 
r following joints are somewhat pale interiorly, but otherwise 
[itennae are black. The legs are yellow, except the coxae and 
nters, which are white on the two anterior pairs and black on 
i sterior. The terminal basal joints of the hind legs are dusky, 
te tibiae are also ringed with black at either end. 
larvae in our breeding cages were also attacked by the very 
of some hemipterous insect of the family Pentatomidae,— 
mtly one of the common “tree bugs” belonging to the genus 
istus.
