Distribution : Typie locality Avalon, Santa Catalina Id., Sept. In 

 coll. Barnes S. Cal., June Aug. Walsinghain recorded it from S. Ore- 

 gon, May. 



Our data may be regarded as insufficient for dropping agrapho- 

 dactylus from our fauna, and this very probably should not be done. 

 We believe, however, that this name is likely to apply to caudelli, 

 rather than to the Californian form, and since we cannot settle the 

 question we prefer to use names of which we can be certain. We 

 submitted a specimen of catalinae to Meyrick as agraphodactyliis, and 

 received the following note in reply. "May be correct, but the type 

 is in poor condition and wanting in definite characters ; I think it may 

 be accepted as reasonably likely." The examination of genitalia of 

 West Indian males should settle the question satisfactorily; consid- 

 eration of superficial characters certainly will not do so, since the 

 type is poor and we are acquainted with two almost indistinguishable 

 species of this immediate group. Grinnell's type is in excellent con- 

 dition, and is a very well marked example of our west coast species. 



58. OlDAEMATOPHORUS ARION n. sp. PI. XLVI, fig. 18. PI. LIV, 



fig. 3. 



Head, thorax and abdomen evenly dotted with brownish gray and white 

 scales. Abdomen with single blackish dorsal dots in hind margins of segments. 

 Antennae with gray-brown and white scales, finely banded. Palpi slender, mod- 

 erate, drooping in the type but probably oblique in nature; white with gray- 

 Lrov.n scales outside. Legs whitish, shaded on one side with fuscous, the 

 hind pair lightly. Tarsi very slenderly dark-annulate at tips of joints. 



Costal margin of primaries dark brownish gray, lighter outward with a 

 heavy spot beyond base of cleft. Remainder of wing lighter brownish gray 

 with a superficial vestiture of white scales. There is a small dark dot in the 

 cell and a larger, but still inconspicuous one before the cleft, not touching base 

 of cleft. A few scattered dark scales near inner margin. Fringes rather darker 

 than wing, darkest in cleft, cut by a few white hairs and tufts especially on 

 outer margin of second lobe. Secondaries light brownish gray, fringes concol- 

 orous. Expanse 22.5 mm. 



Holotype $, Palmeriee, Cochise Co., Ariz., coll. Barnes. 



We associate with this specimen, with some doubt, a single fe- 

 male from Silverton, Colo., July. This 9 agrees with the type in 

 most features but the primaries are whiter, with rather plentiful dark 

 irroration streaking them. We should hesitate to name the one speci- 

 men Init for the peculiar and distinct genitalia. The more salient 

 superficial features are the rather narrow primaries, even color, and
