34 THE CANADIAN ENTOMOLOGIST. 



projecting beyond the head, third joint concealed by the hairs of the 

 others. Front sHghtly brownish, a tuft of pale gray scales at the base of 

 each antenna, the usual deep brown mark from between the antennae to 

 the top of the thoracic crest. Primaries with the usual transverse lines 

 almost white. The basal line makes a bend outward on the median vein; 

 from this it goes in a straight course to the submedian vein ; from this to 

 the posterior or inner margin it curves a little outward. A second line 

 extends from the costa about one-fourth of the distance from the base 

 obliquely to the posterior margin, near the posterior angle. A third line 

 passes straight across the wing from the posterior margin to the second, a 

 little below the median vein. The fourth begins as a white spot on the 

 costa a little more than two-thirds of the distance from the base, and joins 

 the second on the posterior margin, making the usual " V " as in the 

 allied species. The fourth line is slightly S-shaped in its costal third. 

 Outside the fourth line is a subterminal, somewhat zigzag row of black 

 spots, some of which are often faint or obsolete. In the discal cell there 

 is usually a faint oblique line that seems to be a continuation of the third 

 line, though it does not reach the costa, and the end of the cell sometimes 

 appears like a short line. There are three oblique shades of brownish 

 olive more or less distinct, that cross the wing parallel to the second line ; 

 the first, beginning, on the costa inside the basal line, famtly borders that 

 line to the submedian vein, and is seen below that vein on the third line ; 

 the second outside the second line through its whole course, is darkest 

 next the line ; the third from both sides of the fourth line to the middle 

 of the outer border, faint, except along the line. Just outside the S-part 

 of the fourth line are three grayish-yellow spots with a few reddish-brown 

 scales. Secondaries pale smoky gray with a faint whitish line from the 

 fourth of the primaries (as the wings are spread) to the anal angle. 

 Under side, the primaries are about the color of the secondaries above, 

 pale along the costa and terminally, the secondaries paler with a dark 

 transverse line.

Larva. — Length 1.25 inch when crawling, body nearly cylindrical, two 

 black tubercles, close together, on the top of joints 3 and 11. On the 

 dorsum are four bright but narrow yellow lines alternating with narrow 

 black ones. The stigraatal line black ; above this, or the subdorsal space, 

 an irregular alternation of black and white. Below the stigmata a narrow
