250 THE CANADIAN ENTOMOLOGIST 



discal douhle line is the most prominent marking on the wings. 

 It starts as a geminate line at the costa, just beneath which it is 

 outwardly sharply angled. It curves backward from costa toward 

 discal spot, opposite which it is again outwardly angled; then 

 runs a straight course tor a short distance and, making a curve 

 inwardly runs straight to inner margin. At the costa there is a 

 large brown spot joining these geminate extradiscal lines, another 

 at the median \ein and a smaller one on the inner margin. Beyond, 

 the marginal lines run almost straight across the wings with no 

 inward curve as in duodecemlincaia Pack., the only angle being at 

 the costa. Fringe pure white, with black dashes at ends of veins. 

 The wings are not gray as in 12-lineata Pack., but glistening white 

 with brown spots, and the extradiscal is the only line crossing 

 the wing except the two marginal pale lines. Hind wings pure 

 glistening white, with trace of extradiscal line running straight 

 across the whig. It appears as a dot on the inner margin, then 

 on each vein to the cell, where it is elongated and heavy; then in 

 small dots on \eins to tlu' outer margin. There is an apparent 

 marginal line, but the dots are so small and faint that it is difficult 

 to see. I can see no discal spot except perhaps a slight flarkening 

 of the scales. 



Beneath: F"ore wings darker than above, with fuscous tinge, 

 extradiscal and marginal lines showing through. Discal spots 

 black and prt)minent on all the wings. Hind wings white, as above, 

 extradiscal line running straight across the wing, appearing as dots 

 on the veins, no curve visible. Beyond this there are traces of two 

 marginal faint dotted lines. On the abdomen above at base arj 

 two twin dots which sometimes join, forming a black band. Gemin- 

 ate spots are also present on each segment almost to the tip. This 

 species differs from duodccemlineata Pack, in its larger size, pure 

 white colour and brown spots and course of lines.
