(Jround color rather pale ash gray, mottled with smoky. Head aud 

 thorax with the usual lateral line. Primaries with all the markings 

 fairly well defined. Basal line geminate, evident on the costa, and 

 sometimes continued to the black dash. Transverse anterior line gem- 

 inate, well marked throughout in most of the specimens, but occasionally 

 becoming faint, especially in the female, and in some instances entirely 

 wanting. The median shade is marked obliquely on the costa, and 

 sometimes it is traceable below that point. Occasionally it may be 

 followed for its entire course. Transverse posterior line geminate; but 

 the inner line is very feebly if at all defined, and indicated by the paler 

 included shade. The outer portion of the line is Ijlack, narrow, more 

 or less lunulated, and as a whole the line is somewhat S-shaped. Tiiere 

 is a fairly evident subterminal line, which is pale and irregular, varying 

 much in distinctness. There is a series of black dots at the base of 

 the fringes, which are cut with black beyond them. There is a heavy 

 black basal dash, which extends to the traihsverse anterior line, and 

 sometimes crosses it into the median space, though this is rare. A 

 narrow black dagger mark, which tends to obolescence, is opposite the 

 cell; a more ])roniinent dash opposite the anal angle crosses the trans- 

 verse posterior line in the submedian interspace. The ordinary spots 

 are of the ground color or a little paler. The orbicular is irregular, 

 somewhat oval. The reniform rather small, kidney-shaped, well marked 

 inwardly, but usually vague outwardly. The spots are distinctly con- 

 nected by a black line. Secondaries in the male whitish, with a faint 

 smoky tinge; in the female smoky. Beneath white or nearly so, more 

 or less black powdered, the primaries sometimes a little smoky, both 

 wings with the usual outer line and dusky discal spot. 



Expanse, 1.50 to 1.<S0 inches (37 to 45 mm.). 



Habitat. — Canada in June; Maine to VVnshington, District of Colum- 

 bia, west to the Mississippi; White Mountains, New Hampshire, in 

 July; Ithaca, New York, June 17; Otto, New York, July 18; Delaware 

 in March and May. 



It is probable that the range of this species is greater than is indi- 

 cated, but all my material is from the more northern portions of our 

 country. The species is not uncommon in New Jersey, and seems to be 

 not rare in Northern New York and New Hampshire. 1 have some 

 thirty-odd specimens before me which show very little range of varia- 

 tion, except in size. On the whole, the species resemble /*"rc'//J?ra quite 

 closely, but the ground color is a much cleaner gray and the forewings 

 are rather peculiarly mottled by smoky shadings, which are not so dis- 

 tinctly localized that they can be described. The markings contrast 

 more than in furcifcra, and finally, the secondaries in both sexes are 

 much i)aler than in the previous species. In the male they are almost 

 Miiite; in the female they are not as dark as in the in:i\e oi fnrcif era. 

 In the character of the head this species agrees in general with lobeliae. 

 In the leg structure the resemblance is on the whole to farcifera, 

 though comparatively somewhat smaller. The harx)es of the male are
