A REVISION OK THE DELTOID MuTHS — SMITH. 35 



A somewhat dittusc, broiul iitcdiaii band, tullowi'd by a .subterniiiuil 

 abbreviated white hue, wliicli is preceded by a dusky shade, and is best 

 marked toward the anal an^le, becominj;- obsolete toward the eosta. 

 A distinct, bhu'kisli, interrupted terminal Uiie, and a somewhat obscure 

 discal luiiule. Beneatli, whitish, powdery, both wings witli a distinct 

 diseal hmule and a broad extra median band; secondaries with an 

 additional subterminal hue, rei)rodu(;iiig more distinctly that of the 

 ui»|>er side. 



Expanse of wings 21 mm. :— 0.84 inch. 



llAEiTAT. — Long- Island, New York (probably); 



The antenna' of tlu^ male are lengthily bristled hiterally, and the 

 thickening at basal third is well marked, principally by the dense cloth- 

 ing of scales on the outer side, because only two joints are enlarged, and 

 each of these bears a single, stout, pointed spine, somewhat curved at 

 tip, and ot these the basal is the weaker, though a little longer. 



1 have only two male specimens from the Michigan Agricultural Col- 

 lege, without locality label of any kind, but probably from thoTepper 

 Collection, and marked M. (Icccptriadis. It is not impossible that this 

 is a form of M. inconspicualis^ Grote, of which I have seen no male; but 

 the differences are sufficiently great to induce its description at the 

 present time, to call attenticni to the matter, though 1 would not have 

 considered it advisable to name it under other circumstances. The 

 course of the lines is practically like those of M. incon,spicnali,s, but 

 they are so much more prominent and so much more diffuse, while 

 the coloration is so markedly different, as compared with its ally, that 

 I hesitate to consider them identical without further material. 



Zanclognatha inconspicualis, Grote. 



1883. Grote, Canadian Entomologist, XV, 30, Mefjachiiia. 



Ground color an even, dull, smoky-brown or fuscous. Mead and 

 thorax concolorous. Primaries with basal line evident, narrow, extend 

 ing to the median vein. Transverse anterior line blackish, narrow, 

 somewhat dilated on the costa, curved in the interspaces, and with a 

 slight general outcurve in its course as a whole. Transverse posteri(U- 

 line threadlike, blackish, vsomewhat dilated on the costa, denticulated 

 on the veins, outcurved over the cell, and more or less incurved beneath. 

 Subterminal line pale, variably distinct, its course nearly straight, 

 with very small undulations, preceded by a variably marked blackish 

 shade. Orbicular wanting. Keniforin small, oval, blackish, not well 

 marked. A broken, black, terminal line. Secondaries slightly paler, 

 with a dusky median line; a pale or whitish subterminal line, preceded 

 by a dusky shade, more evident near the anal angle, and an obscure 

 discal lunule. Beneath gray, fuscous powdered, each wing with a 

 dusky discal lunule, a dark extra median line, and a more or less obvious 

 pale subterminal line. 



Expanse of wings, 1!) to -Uium = 0.78 to 0.82 inch.
