106 THE CANADIAN ENTOMOLOGIST. 



description there given. It is proper to say, however, that the palpi and 

 legs should rather be described as silvery gray, or as gray, with blackish 

 markings on the legs, rather than as silvery white stained with fuscous. 

 Captured specimens of imitatorella were for a long time placed among 

 cd'milariella, though a close examination would have shown the difference. 

 I did not, however, observe the difference until I bred from a new larval 

 case a species which I recognized at first as T. ccemitariella. On exam- 

 ination of the specimen and comparison with bred specimens of ccemitari- 

 ella — a single specimen of each — a difference was found in the costal and 

 dorsal streaks on the wings, but an examination of other specimens 

 showed that this could not be relied on, as both species vary greatly in 

 this respect, as these markings vary from lines which cross the wings to 

 mere dots on the margin. The legs of imitatorella are more decidedly 

 black than in the other species, but the only important difference in the 

 imago is in the antennae. The antennae of cosmitariella are robust and 

 yellow banded above with fuscous lines, while those of imitatorella are 

 quite slender and in color shining black. There is also a decided differ- 

 ence in the larval cases ; that of ccemitariella is much depressed, narrowing 

 before each end, that is, scalloped on each side before each end, the 

 under side truncated at each end and the upper projecting like the bowl 

 of a spoon beyond it ; the case of imitatorella is scarcely at all depressed, 

 it is not scalloped as in ccemitariella, the upper side does not project 

 beyond the lower, and the anterior end is narrower than the posterior one. 



T. croceoverticella. A T . sp. 



Dark brown, in some lights strongly bronzed ; head saffron colored ; 

 antennae dark brown ; palpi a little paler than the head ; under surface 

 silvery whitish faintly tinged with golden yellow ; wings rather wide ; 

 ciliae grayish, with two brown hinder marginal lines, one at their base and 

 the other beyond their middle. Al. ex. a little over ]/^ inch. Kentucky. 



T. tkoracestrigella. N. sp. 



Much like the above, but larger, having an al. ex. of more than $4 

 of an inch. The fore wings are simply dark brown, without bronzy 

 reflections ; and so are the ciliae, which show no hinder marginal line ; 

 the hind wings also are brown, though paler than the fore wings. The 

 head is more reddish saffron, and a line of that color extends from the 

 head to the tip of the thorax. Otherwise it resembles the species above 

 described.
