June, 1909] Smith: New Species of Noctuid.e for 1909. 67 



Primaries, in the male the maculation tends to become altogether lost, the t. a. and 

 s. t. lines being most frequently defined and thereniform usually marked by a reddish 

 cloud. In the female the primaries are more powdery, the veins tend to become 

 darker, and most of the maculation is usually traceable, the s. t. line being always 

 most obvious. In none of the specimens is all the maculation present, so that the 

 description is made from several examples. Basal line geminate, the component parts 

 widely separated, almost crossing the wing and strongly angulated. T. a. line single, 

 diffuse, outwardly angulated at its middle, inwardly so on the subcosta and submedian. 

 A broad, diffuse median shade is traceable across the wing in most examples. T. p. 

 line single, irregular, diffuse, only a little outcurved over cell, and almost less in- 

 curved below. A series of interspaceal blackish spots mark the s. t. line. A series 

 of blackish terminal marks, beyond which is a narrow, interrupted pale line at base 

 of fringes. Claviform short and broad, concolorous. Orbicular round or nearly so, 

 not outlined, a little paler than the ground, with a dusky center. Reniform large, 

 upright, incomplete, a little constricted at middle. Secondaries white with a series 

 of black terminal lunules and a tendency toward a series of dusky extra-median venu- 

 lar dots. Beneath white, primaries more or less powdery ; all wings with a more or 

 less obvious discal spot and a tendency to an extra-median line. 

 Expands, I.40-I.70 inches = 35-42 ram. 



Habitat. — Pullman, Washington, April and May. 



Seven males and six females, all in good condition, received from 

 the Experiment Station some years ago and but recently separated out. 

 The antennae of the male are distinctly serrate and fasciculate and 

 therefore this is related to indiirata and curia/is. It is however a much 

 larger species than argus, broader winged, and with quite a different 

 appearance. The marked difference between the sexes in this species 

 is quite characteristic, and besides the differences already pointed out, 

 it may be added that the males run smaller, although the largest male 

 more than equals the smallest female. 



Xylomiges tantiva, new species. 



Ground color bluish gray, powdery. Head and thorax concolorous, patagia tend- 

 ing toward a dusky submargin. Primaries powdery, all the transverse maculation 

 obscured, tending toward a dusky shading over costa and in the terminal space. So 

 far as they are traceable, the median lines are much as in nicalis ; but always incom- 

 plete and the t. p. line often altogether lost. S. t. line pale, even, preceded by a 

 narrow dusky shade which is sometimes more or less broken ; but never forms a series 

 of separate spots. A dusky terminal line. Fringes interlined with pale. Claviform 

 moderate in size, quite usually traceable. Orbicular round, obscurely outlined, a 

 little paler than the ground, with a dusky center. Reniform large, upright, a little 

 constricted at middle, with a shading of reddish or brown scales outwardly. Sec- 

 ondaries white, with dusky terminal lunules and a tendency to a dusky, venular extra- 

 median line. Beneath white, more or less powdery on primaries ; all wings witli a 

 discal spot and a tendency to an extra-median dark venular line. 



Expands, l. 40-1. 60 inches = 35-40 mm.
