Nephelodes demaculata sp. nov. (PI. XV, Fig. 3). 



Head and thorax deep ochreous, at times tinged with purplish ; primaries 

 deep ochreous, in some specimens with a decided violaceous tinge ; the macu- 

 lation is of the usual type but so obscured as to be practically obsolete; the 

 t. p. line is the best defined due to the paler character of the subterminal and 

 terminal areas which further show the veins outlined in dusky; the outer half 

 of the median area is often the darkest portion of the wing; secondaries deep 

 smoky with pale fringes. Beneath light ochreous with faint discal dots and 

 obscure postmedian line. Expanse 38 mm. 



Habitat: Plumas Co., Calif. (Aug.-Sept.) 7 S, 1 9. Types, Coll. 

 Barnes. 



The peculiar coloration of this species, which resembles that of 

 some of the Agropcrina group, should readily distinguish it from pec- 

 titiata Sm. with which it agrees in antenna! structure; the lack of 

 maculation is also characteristic; in none of our specimens is the reni- 

 form distinct but in a few it can just be traced as a faint palish patch. 



Xylomyges cognata Sm. (PI. XVI, Fig. 10). 



We have already had occasion (Contrib. II (1), 16, PI. VII, 

 Figs. 13-15) to comment on the variability of this species; it was 

 described from three S specimens from Vancouver Is., B. C, Oregon 

 and Colorado (Bruce), this last specimen being in the collection of the 

 National Museum and marked "type" ; we have seen no other Colo- 

 rado material besides this type, but specimens from Vancouver Is. 

 which we compared with it agree so that this form may be regarded 

 as typical; Smith's figure of the species (Trans. Am. Ent. Soc, XXI, 

 PI. V, Fig. 3) also agrees with our figures 13 and 14. With regard 

 to this latter specimen it bears the label "Calgary, Alta." but is prob- 

 ably a portion of the material distributed by Neumoegen labelled 

 indiscriminately "Ft. Calgary, Brit. Columbia" or "N. W. B. C," and 

 which was mostly collected by Danby in the Kootenay District of 

 British Columbia; Mr. Wolley Dod states that the species never has 

 been taken at Calgary, Alta. 



We have recently received more material of the California form 

 (which we figured previously in Fig. 15) froin Eldridge, Sonoma Co. ; 

 it diflfers from the typical form in the even olivaceous gray colora- 

 tion of the primaries with obscure maculation ; it is also considerably 

 smaller in size. As it seems perfectly constant in these characteristics 

 we propose for it the name minorata (PI. XVI, Fig. 11), our types
