THE CANADIAN ENTOMOLOGIST. 119 



Mesoleuca Walkerata, n. sp. — Expanse, 28-30 mm. Best described 

 by comparison with the familiar hersiliata. On fore wings the basal line 

 turns outward below costa, forming a long sharp point below subcostal 

 vein, and another above vein 1 in general course receding toward base. 

 In hersiliata this line curves outward at costa, then runs in straight line 

 to inner margin. Basal space gray, succeeded by an orange-brown band, 

 rather narrow at costa, the discal line which forms the outer limit 

 irregularly toothed across wing until it reaches vein 1, which it follows 

 outwardly to about the width of band, then at right angle drops to inner 

 margin. This band above vein 1 is sometimes entirely obscured by gray 

 atoms, leaving only the square block below vein 1, in orange-brown or 

 yellow. This line in hersiliata runs nearly parallel with basal line, or with 

 an outward trend near inner margin, but not at all as in Walkerata. A 

 band" of dark gray, bordering discal line outwardly, follows its sinuosities 

 and above inner margin, also abruptly turns outward at vein 1, forming 

 between that and inner margin a square block of dark gray scales. A 

 similar band runs from costa to angle, within extra-discal line, from which 

 to inner margin it fades out into the paler area of gray, traversed by one 

 or two wavy lines, which occupies the central discal space. Discal dots 

 small, linear, black. The extra-discal line starts from costa nearer the 

 apex than in hersiliata, its outline much the same, except that the tooth- 

 like projections are angulate, not rounded, and the notch opposite discal 

 point is barely traceable in o* type, while in the $ it is quite apparent. 

 This notch is not always a deep indenture in hersiliata, but is generally so. 

 Colouring and lines of marginal space as in hersiliata. Hind wings evenly 

 dusky, with faint extra-discal, but rather more angulate, and beneath all 

 parts as in hersiliata. 



Type, S taken in Catskill Mts., July 2, 1905; type, $, July 1, 

 1899; co-type, one $ from same locality in the writer's collection. These 

 are all I have secured in many years' collecting, so that the species is a 

 rare one. In the Brooklyn Inst. Museum are specimens taken in the 

 White Mountains of New Hampshire many years ago. 



The second species is referred to by Dr. Packard (Mono., page 438), 

 where in describing Cymatophora (Cleora) larvaria, Guen., he says : 

 "This common species is divided into two races, one smaller and darker, 

 with the antennae more broadly pectinated, while the outer line in the 

 hind wing is less angulated,'' etc. They are not races of the same species, 

 as their structure and markings amply demonstrate, though they fly at the 

 same season. I take both in moderate quantity each year in the Catskill 

 Mts. I have named it 



Cleora takenaria, n. sp. — Expanse, 25 mm. Palpi moderately stout, 

 dark brown, tipped with white. Front, thorax and abdomen pale whitish-ash,
