26 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
rounded, without horn-lke processes, but with a pair of slender 
sete. This stage has not hitherto been described, the description _ 
given by Weed being evidently that of the pupa of some other 
species. (See fig. 9, e, 7.) | 
The adult or moth—The description given by Clemens is as fol- 
lows: “ The head and antenne shining, dark brown, face ocherous. 
Fore wings uniform, shining, dark brown with a purplish tinge, — 
slightly dusted with pale ocherous; cilia of the general hue. Hind © 
wings dark gray; cilia with a rufous tinge.” (See fig. 9, a, 0.) 
FOOD PLANTS. 
In his original description Clemens gives the food plant as apple. - 
Chambers states that he bred it from ie es of different species of — 
haw (Crategus), sweet-scented crab (Pyrus coronaria), blackberry il 
(Rubus villosus) , and raspberry (Rubus occidentalis), and adds that 
it probably mines other species of Rosaceee. Later Clemens saya | 
that this species, as well as certain others, feeds indifferently on 
leaves of Crateegus, Prunus, and Malus. { 
In 1873 Messrs. Frey and Boll described 7%scheria enea, bred from | | 
Rubus villosus, and Tischeria roseticola from Rosa carolina. Tn the ~ 
Cincinnati Quarterly Journal of Science Chambers adds tl: a 
berry (ubus canadensis) to the food plants of Tischerta mali 
and does not consider 7’. enea of Frey and Boll, from blackbe ~§ 
tinct from 7. malifoliella; he regards as belewenne to this species ' 
the specimens bred from all the species of abuse Crategus, and — 
Pyrus. He also doubts the distinctness of 7’. roseticola. However, 
in a later publication, “ Tineina and Their Food Plants,” Mr. Clemens 
recognizes the two species of Frey and Boll above Shea, and as food — 
lente of 7. malifoliella gives Crategus, Pyrus coronaria, and Pyrus — 
malus, omitting as food plants species of Prunus, Rubus, and Rosa, 
assigning the two latter as food plants of wnea and roseticola, re- . 
spectively. The distinctness of the three species was again recog- 1 
nized by Chambers in his Index to the Tineina of the United States 
and Canada, ae more recently by Doctor Dyar in his “ List of N. A. 
Lepidoptera.” x 
Finally Mr. Pettit notes serious damage to blackberries from 
T. malifoliella at the South Haven substation in Michigan, and — 
states that the insects seem to breed in the neighboring apple trees 
and come to the blackberries from them. However, in the absence 
of definite breeding work and the critical comparison of adults thus 
secured, it will be best to follow the evident conclusions of Chambers 
and Dyar, and limit the food plants of 7. malifoliella to species of 
Crategus and Pyrus. During the present season (1907) the insect
