AMERICAN LEPIDOPTERA. 27 



Hab.—Caimdn; New England States; Northern New York; 

 Northern New Jersey. 



Seven males and seven females, practically alike, except for a 

 slight difference in the shade of gray. The color is bright, clear 

 and does not give the impression of softness. 



The antennse of the male are shortly ciliated and not thickened 

 by scales toward the base. The species seems rather abundant. 



Xylina longior Smith.

 Ground color a bright bluish ash gray, with a more or less obvious admixture 

 of reddish. Head with black scales between the antennse and the front also 

 blackish or smoky. Collar with a distinct reddish shade crowned by a short 

 blackish line, above which the scales are white tipped at the base of the promi- 

 nent crest. The thorax has some reddish scales intermingled, and there is a dis- 

 tinct black line at the sides of the patagiai covering the base of the wings. The 

 primaries are, in most cases, quite distinctly marked. There is a blackish basal 

 streak which extends below the median vein and reaches a little beyond the 

 inner fourth of the wing. The tendency of this streak is to become lost. The 

 t. a. line, when present, is very narrow, black, but shaded with smoky and em- 

 phasized by a few preceding white scales. It is strongly bent outwardly, irregu- 

 larly in the interspaces and forms an acute tooth at the middle of the subinedian 

 inters|)ace, where it touches a short and prominent black dash. It is then bent 

 inward, so that it reaches the internal vein just about as far from the base as is 

 the inception of the line on the costa. The tendency of this line is also to disap- 

 pear and to leave only a black streak extending from the internal vein about 

 one-fourth from base to middle of the submedian interspace. This portion of the 

 line is distinctly present in all the specimens seen by me. The t. p. line is not 

 complete in any specimen. It is traceable in one example as a lighter shading 

 through the darker powderings in the costal region. It is marked by black points 

 below the cell and by blackish scales which connect it with the short black dash 

 already described as attached to the tooth of the t. a. line. Below that point it 

 is not traceable in any specimen. The s. t. line is indicated only by two oblique, 

 triangular, blackish or brown shades. The first of these starts from a blackish 

 point between veins 4 and 5 and reaches the external margin just below the apex. 

 The second of these shades is more brownish and starts from a point below vein 

 2, reaching the external margin just below vein 4. The* ordinary spots, at least 

 the reniform, are traceable in most cases. The orbicular is large, oval, oblique 

 and is outlined by a few paler scales. The reniform is large, broad, a little con- 

 stricted in the centre, extending inward inferiorly. so that it touches and may 

 become connected below the orbicular. It is marked inferiorly by a reddish 

 shading and is outlined by whitish scales, which, at the latter margin, are pie- 

 ceded and followed by a black shade that makes this part of the wing character- 

 istic. All the veins are somewhat marked by black scales. The secondaries are 

 smoky brown, the fringes a little paler and with a pinkish tinge. Beneath smoky 

 gray, powdery, the disc a little darker, both wings with discal spots. 

 Expands 39-47 mm. — 1.56-1.88 inches.
