Indies and Mexico were described as North American, it is possible 

 that this, and other insects without locality, may not belong to the 

 North American fauna. I have never seen the insect.

Expands 20 — 26 mm. Blackish and gray. Fore wings with a faint and incon- 

 stant shading of red at base, usually absent. Basal field of the wing whitish 

 gray, before the line shaded with blackish. Inner line continuous, w^hitish gray, 

 followed by a blackish line, twice indented, usually roundedly exserted in the 

 middle. Median space washed with gray anteriorly and along costa. Discal 

 mark consisting of two generally fused dark dots, obliquely placed, slightly re- 

 lieved by whitish. Outer line pale, tolerably even, indented below costa, oppo- 

 site cell, and again less distinctly on submedian fold. A row of blackish terminal 

 points; fringes concolorous. There is a more or less evident median shade, 

 which obliquely margins in an irregular fashion the outer and darker portion of 

 the median space ; sometimes a faint reddish tinge is perceptible about this shade 

 line, on submedian space. Thorax ashen, sometimes faintly ruddy. Hind wings 

 subpellucid, shaded with fuscous, darker in the 9; fringes paler, neatly inter- 

 lined near the base.

Var. qiiiiiquepniictella Grt., N. A. Ento. i, 50, 1880; i, 68, pi. 5, fig. 6. 

 Expands 21 — 23 Dim. Closely allied to contatella. It differs by its smaller 

 size, the last two scallops of the interior line more or less evidently pure white, 

 and contrasting; tiie line is followed by three dots, one below costa indistinct 

 and sometimes absent; the second at the median vein at the inception of the 

 white portion of the line; the third on submedian fold. These dots seem to be 

 the remainder of the blackish shade following the white portion of the line. 

 The discal dots are separate: the outer line is more denticulate; the wing is 

 more noticeably stained with red. Hind wings and under surface as in contatella.

 Prof Comstock gives the following description of larva and pupa 

 of contatella and its variety : 



Larva. — "The full grown larvje were nearly an inch in length, of a grayish 

 green color above, more or less tinged with pink, especially on the third and 

 fourth segments and between the folds ; under side pea-green ; some of the larvae 

 were of a yellowish green color, darker green anteriorly, head yellowish lirown 

 with irregular black blotches, thoracic plate green, with a few black spots, an- 

 terior margin yellowish, posterior pale brownish. 



Pupa. — Length 10 mm., rather stout, color chestnut-brown ; anterior end 

 rounded; posterior with a minute beak curving down slightly and armed at the 

 end on each side with a sharp, stout spine, extending obliquely out and down- 

 wards. In a row between these at equal distances are four slim filaments, much 

 longer than the spines and hooked at the end. The abdominal segments are.
