THREE NEW NOCTUIDS FROM BRITISH NORTH AMERICA. 



BY JOHN B. SMITH, SC. D., RUTGERS COLLEGE, NEW BRUNSWICK, N. J. 



To the courtesy of some of my correspondents from British North 

 America I owe a series of specimens, some of which proved undescribed. 

 The species sent by Dr. Fletcher is of some economic importance, and its 

 prompt description seems desirable. The other species have been in 

 MSS. for some time, and were intended to form part of a lengthy descrip-

Semiophora Youngii, n. sp. — Ground colour varies from carneous 

 gray to smoky brown, variably powdered with black or suffused by darker 

 shadings. Front of head and tips of palpi always gray ; sides of palpi 

 blackish brown. Male antennae with lengthy, slender, yellowish pectina- 

 tions. Collar inferiorly rusty red or brown, surmounted by a blackish 

 or darker line or band, and more or less obviously gray tipped. Discal 

 tufting gray or at least paler than ground ; patagiae a little gray speckled. 

 Primaries with all the usual maculation well defined. Basal half line 

 black, single, twice dentate, followed by a gray shade line. Between this 

 line and base is a gray powdering, always obvious and sometimes 

 prominent; beyond it on the sub costal is another less prominent shading, 

 which extends to the t. a. line. T. a. line geminate, more or less broken, 

 upright or a little outcurved, outcurved in the interspaces, though not 

 prominently so. Outer line black, inner line obscure, scarcely defined, 

 intermediate space gray. In one example the gray included space only is 

 visible. T. p. line geminate, evenly outcurved over the cell, inwardly 

 oblique, or with only a slight incurve to the inner margin. Inner line 

 black or blackish, lunulate, outer line smoky, even ; included space gray,
