patch extending almost to inner margin. The first costal patch 

 is linear and points towards first venular dots of outer margin; 

 a pale rust-red line runs from this patch almost to inner margin. 

 The second costal patch is not as strongly angulated on costa as 

 the first. A line runs from it to vein 3 in a straight line just 

 inside the black linear discal dot, and then curves backward 

 towards body to inner margin. The third costal patch is smaller 

 than the others but has a pale line running from it to inner 

 margin, bending outwards in a curve opposite discal line to 

 the middle of vein 2, then going straight to inner margin. The 

 fourth costal patch is very large, 1}/^ mm wide and 2 mm long; 

 it seems to have a notch near the bottom on the outer side and 

 from the base of this runs a pale rust-red line to inner margin 

 straighter than the other lines. The apex of the fore wing is 

 light bluish ash, and near the base of the fourth costal spot is 

 the broad reddish-brown band, widening as it approaches inner 

 margin, being more distinct in some specimens than others, as are 

 also the costal lines, which hardly show in one specimen. The 

 fore wings are finely powdered with red-brown striga^ and have 

 black venular dots on outer margin. The hind wings have traces 

 of two pale brown lines beyond discal spot, but this may be an 

 arrangement of strigse as it shows in only one specimen. The 

 general colour is lighter ashen with a yellowish tinge and the 

 venular dots are the same as on fore wings. Beneath the wings 

 are densely strigate, the lines of fore wings showing through very 

 faintly from the second and third costal patches on each side of 

 discal spot. Beneath third and fourth patches of fore wings the 

 costa is bright orange, and the apex has brown cloudings. The 

 hind wings are densely strigated also and there are two pale red 

 brown lines crossing wing beyond discal spot. The veins are 

 ochreous and the dots are between, at base of fringe. 



Type,— 1 cf , August 8, 1909. Half Way House, Mt. Wash- 

 ington, N. H; taken at light by myself. 



Cotypes— 2 c^s, July 27, August 11, 1909, N. E. Harbor, 

 Maine; taken by Dr. Charles S. Minot, in Boston Society of 

 Natural History collection. This species resembles M. praeatomata 

 very slightly. 



We owe our readers an explanation of the extremely late 

 appearance of our December number. Part of the proofs went 

 astray in the mails and the discovery was not made until after a 

 considerable loss of time. This is the more regrettable as it has 

 resulted in the delay of the January number also.
