264 AMERICAN LEPIDOPTERA. 



species resembles verticalis Grt., in general appearance and 

 type of maculation ; but is narrower winged, the primaries 

 more obtuse and the maculation more complete and clearly 

 defined. A somewhat characteristic feature is the darkened 

 outer portion of the median space, which in verticalis is con- 

 colorous. In the specimens before me the single male has 

 more red than any female, while the females differ in the 

 amount of shading in the s. t. and terminal spaces and the 

 amount of contrast between the lines and shades ; but always 

 the specimens are very neatly and cleanly marked. 



The male antennae are serrate and fasciculate, the lateral 

 processes being well marked and conical, but not forming 

 true branches. 



Fishia instruta n. sp. 



Pale ashen-gray, with a bluish tint, very even ; markings narrowly 

 and rather well defined, but not contrasting. Collar with a narrow, 

 clear-cut median black line. Patagia with an indicated sub-marginal 

 line. Primaries with a narrow black basal streak which does not reach 

 the t. a. line. T. a. line single, narrow, black, preceded by white 

 scales, strongly dentate in the interspaces, the largest tooth in the sub- 

 median interspace, and to it is attached the concolorous, black-edged 

 claviform, which extends across the median space and reaches the in- 

 curve of the t. p. line. T. p. line black or blackish, less defined and 

 more diffuse toward costa, outwardly dentate on the veins, incurved 

 in the sub-median interspace, where it is most distinct and preceded 

 by white scales. S. t. line marked by a series of three to five irregu- 

 larly placed short, black, interspaceal dashes, some before and some 

 beyond a series of obscure, whitish dots. No terminal line. Fringes 

 concolorous, cut with yellowish at the ends of the veins, Orbicular 

 large, oblique, oval, narrowly black ringed, concolorous or very 

 slightly paler. Reniform large, kidney-shaped, inwardly black-edged, 

 with white or whitish scales forming an inner, more or less defined 

 ring; it may be concolorous or a little paler. Secondaries white, 

 powdery, with a broken punctiform dusky extra-median line, a vague 

 discal spot and a well-marked blackish, lunulate terminal line. Be- 

 neath whitish, rather evenly powdery, with a well-marked small discal 

 spot on all wings and a vaguely marked extra-median line. 



Expands, 1.50-1.58 inches = 27-29 mm. 



Hab. — De Clair, Manitoba, Sept. 3-15. 



Four males, in good condition, collector unknown. The 

 species resembles yosemite Grt., in the uniform coloration of 

 primaries ; but these are gray, without trace of brown, and 

 the secondaries are white, without trace of fuscous. Yose-
