and is usually darker around the edge and on the latticed ridges. The 
exact shape is variable, but the points mentioned form its boundaries 
between which the outline may be contracted or expanded. Length, 
6. 7 to 9.5 mm. 
Cocoon with the characters of the group. 
Food-plants: Oak, wild cherry, birch, hickory, chestnut, witch- 
hazel and sour gum have been observed. 
Additions and Corrections. 
As it was necessary to make the corrections to the account of T. 
pallida with this plate, I have included all additions and corrections that 
have occurred to me to date, to all the articles that I have published on 
Eucleid larvae in this Journal. Corrections to the introductory article 
will be deferred to the concluding remarks. 
Apoda y-inversa Packard. 
This Journal, III, p. 151. Omit the reference to the larva. A. 
y-inversa larva was undescribed previous to our article. 
This Journal, III, p. 152, lines 8, 9. Omit the words “in which 
the larva does not feed.” P. 154, Stage /.—Add “ The larvae feed in 
this stage. Length, .9 to 1.5 mm. Subdorsal setae of joints 5, 7, 9 
and 11 lean outward, lateral of joint 5 leans upward.” 
This Journal, III, Plate VI, Fig. 1. The alternation of the setae is 
wrongly represented. 
Sibine stimulea Clemens. 
Comparison may be made with the allied South American species 
referred to by me (Can. Ent, XXIX, 77). 
Tortricidia pallida Herrich-Schaffer. 
This Journal, IV, 167, et seq. Special structural characters , line 
5 of paragraph, omit the words “ smooth or;” p. 168 line 10 for “ setae 
practically” read “tubercles.” 
Affinities , Habits , etc. Read as follows: This larva is typical of 
the red-marked smooth Eucleids, a subdivision of the Palaearctic group. 
It is most nearly allied to T. testacea , less closely to H. flexuosa. It 
represents a more primitive state than Apoda in that setae i a and i b on 
joint 4 and i and ii on joints 5 to 12 are partly united into a furcate or 
Y-shaped spine, both limbs of equal length, whereas in Apoda one limb 
has been reduced to a slight prominence.
