tip. Thorax crossed by dark and gray transverse lines, the posterior 

 t liftings uplifted and gray-tipped. Dorsal tuftings of abdomen 

 small, sometimes gray-tipped. Primaries transversely strigillate, 

 the strigillation continuous, brown, and many of them completely 

 crossing wing. Basal space darker than the rest of the wing. Basal 

 line brown, geminate, usually obvious. T. a. line a broad, rather 

 even, deep brown band, preceded bj^ a yellowish line, almost direct 

 from costa to middle, then bent inwardly oblique to inner margin. 

 The median space as it begins at the t. a. line is gray, and is the palest 

 portion of the wing, relieving the dark t. a. line ; outwardly it shades 

 into the ground, sometimes before the middle, sometimes hardly be- 

 fore the t. p. line. The orbicular is a small brown dot, which is some- 

 times lost. Eeniform gray, lunate, with a rusty brown annulus 

 within its area, and poorly defined by a darker border. T. p. line 

 narrow, linear, rich velvety brown, irregular, outwardly bent from 

 costa to vein 7, then inwardly bent opposite the reniform and then, 

 with three sinuations, obliquely inward to the internal margin. From 

 the apex a dark shade extends obliquely inward to the s. t. line oppo- 

 site cell. S. t. line blackish brown, irregular, rather close to and as a 

 whole parallel with t. p. line; inwardly diffuse, outwardly bordered 

 by rusty brown. Terminal area usually only a little darker than the 

 inner portion of median space, darkened by the brown striga?, with a 

 narrow, crenulate terminal line. Secondaries smoky-yellowish at 

 base, and usually to an extra-median brown shade, which is like the 

 paler ground of primaries. The disk is crossed by dusky transverse 

 shadings, and the terminal area is strigillate. Beneath yellowish, 

 powdery, more or less strigillate with brown, sometimes gray along 

 costa and outer margin: a dusky discal lunule and a median and 

 extra-median dusky line on all wings: the latter with an outward 

 angle below costa of primaries.

Habitat. — Maine to Florida, west to Wisconsin. 



In the material before me there is a very dark richly colored ex- 

 ample from Mount Katahdin, Maine, dated in July. Specimens from 

 Webster, New Hampshire, are dated in May, and some very hand- 

 some material from New Brighton, Pennsylvania, was collected by 

 Mr. II. D. Merrick in late April. 



This is one of the most characteristic species of the genus, and 

 while it varies somewhat in brilliancy of coloring and amount of con- 

 trast, there is never enough to raise a doubt as to the species. The 

 peculiar elevation of the posterior thoracic tufting and its contrasting 

 color are distinctive features belonging to none other of these species 

 except Zale horrida. 



The spinulation of the middle tibia is distinct in both sexes, and 

 in some examples spines occur also between the two pairs of spurs
