Monterey and San Diego Cos. but as their large size (38 nini. in both 

 sexes) is apparently constant we believe we are justified in proposing 

 to use the racial name grandis, our types being 1 S from Duncans, 

 B. C. (Mch. 24-30) and 3 9 's from Victoria, B. C. (Apr. 8, 13. 16) 

 1 9 , Paratype (Victoria, Apr. 13) being in the American Museum 

 Collection. 



We have before us two specimens from Arizona which we discov- 

 ered mixed up with a race of speciosata to which we will refer later; 

 in the S sex the Uncus is enormously forked with a long thin neck, 

 quite distinctive from any other species we know. We describe it as 

 follows. 



Hydriomena furculoides sp. nov. (PI. V. Fig. 15). 



Palpi long, thin, purple-brown tipped with ochreous ; head and thorax pale 

 greenish-yellow, the latter with two black spots on prothorax and one at base of 

 primaries; metathoracic tuft tipped with black, abdomen ochreous. Primaries 

 pale greenish-white suffused with purplish-brown 

 and crossed by bands of this color; line l(subbasal) 

 line, bent strongly outward just below costa, then 

 perpendicular to inner margin forming a right angle 

 in the cell with a slight inward bend in submedian 

 fold ; band 2 starting from a large costal patch, then 

 rather indistinct and more or less fused with the 

 following band owing to dark scaling in central 

 area of wing; band 3 (antemedian) bent outward 

 below costa, then rather straight and perpendicular 

 to inner margin ; median space pale, slightly 

 sprinkled with dark scales and with a dark streak 

 above vein 4; line 4 (postmedian) bent out below 

 costa, then jagged and toothed to vein 4 below which it is more or less obsolete 

 as a fine line close to the subterminal band ; snbterminal space similar in color 

 to median area ; subterminal band broad, with irregular edges, approaching close 

 to outer margin at vein 3 ; terminal area with very broad purplish streaks on 

 the veins which mostly connect with the subterminal band, leaving only small 

 terminal patches of the pale ground-color visible and a costal patch of same 

 color just beyond s. t. band below which is the usual black streak ; fringes pale 

 ochreous, dotted with brown at ends of veins. Secondaries pale smoky with 

 traces of a discal dot and somewhat crenulate postmedian line. Beneath whitish 

 with maculation of upper side partially visible ; secondaries with distinct discal 

 dot and rather sharply angled postmedian line. E.xpanse 30mm.
