THE CANADIAN ENTOMOLOGIST. 13 



The protuberant, roughened front is somewhat unusual in this genus, 

 but is not so marked as to require a separate generic term. 



Caradrina drasteroides, n. sp. — Ground colour a creamy gray, with 

 the yellowish tinge well marked. Head and thorax immaculate. 

 Primaries powdered with black scales, which gives the gray tinge an 

 emphasis ; most of the s. t. and terminal spaces distinctly and evenly 

 gray. The ordinary lines are not well marked. Basal line marked 

 on costa only or not at all. T. a. line barely traceable by the absence of 

 black scales ; outwardly bent on the median vein, inwardly angled on the 

 submedian. T. p. line better defined, geminate, only a little outcurved; 

 inner line blackish or brown, sometimes emphasized on the veins ; the 

 outer line marked only by the darker s. t. space which relieves the 

 pale shade following the inner dusky line. The median shade line 

 is smoky or deeper luteous, well removed outwardly, and outwardly 

 diffuse to the t. p. line. S. t. line whitish, almost even, a little better 

 defined on the costa by a slight darkening in the s. t. space ; well defined 

 inwardly, somewhat diffuse outwardly. A series of minute black terminal 

 dots, which may be wanting. Orbicular and claviform wanting. Reniform 

 oblique, without definite outlines, dusky, obscured by the median shade, 

 which crosses and completely involves it. Secondaries snowy white, with 

 or without a small dark discal spot and a more or less obvious powdering 

 of black scales at the base of the fringes. Beneath, primaries creamy 

 white, the yellow most obvious along the costa, with a more or less 

 obvious extra-median dusky line, and with or without a discal spot. 

 Secondaries white, more or less creamy and powdery along the costa ; a 

 partial outer line and sometimes a small discal dot. 



Expands 27-31 mm. =1.08-1.24 inches. 



Habitat: Southern California ; Arizona. Two male examples; one 

 in good, the other in fair condition. 



The smaller specimen is from Arizona, and comes from the 

 collection of Dr. Ottolengui. The larger specimen is from Southern 

 California, and has been in my collection nearly or quite ten years 

 awaiting a mate. The reference to Caradrina is not quite satisfactory, 

 because of the wing form. This resembles more that of Drasteria. and 

 there I expected at first to place it, but the species is obviously a typical 



trifid. 



The vestiture is scaly, just a little roughened, forming no tufts of any 

 kind. The palpi hardly exceed the front. The antenna? are very shortly 

 ciliated,
