A well-preserved series of types with Chambers' written labels 

 attached are found in the Museum of Comparative Zoology. 



In the U. S. National Museum are several specimens, compared with 

 and found identical with the types by the writer in 1900. One of these 

 is named by Lord Walsingham; others were received from Dr. Dietz. 



All are from Colorado, as also are Chambers' types. 



Chambers recorded a variety from Kentucky, with which I am not 

 accjuainted. 



Dr. Dietz recorded "'a verv close variety'' from New Jersey, but I 

 think it im})rol)able that it really was this Western species. 



It is a typical Gnorintoschema.

The unique t3^pe of this species is in the Museum of Comparative 

 Zoology. It is in very poor condition, so poor that I did not at all 

 recognize the very charming species it really- is and described it in- 

 manuscript from a tine specimen in National Museum, bred by Mr. 

 Koebele. However, on final examination last January I realized this. 

 Chambers' meager description gives a very poor idea of the true 

 appearance of a perfect specimen. 



For this reason I append my description: 



Auteniue reddish white, each joint aniudated with black. Labial) 

 palpi of typical gnorimoschema form, whitish, sprinkled with black 

 atoms; terminal joint just before the tip nearly black. Face reddish| 

 white, head and thorax reddish white, sprinkled with small dark;; 

 atoms. Forewings pale rosy white, each scale tipped with black;; 

 near base of wing a transverse dark rust brown fascia, narrowly; 

 edged on both sides with light 3'ellowish brown. (This fascia is notj 

 mentioned by Chambers, though detectable in the type.) 



On middle of cell are two large circular dark rust-brown spots, one! 

 above the other, edged with lighter l)rown. A somewhat smaller sim-1 

 ilar spot at the end of the cell. Toward apex a few scattered all ' 

 black scales; extreme apical edge black; cilia dirtj^ white. Hindwings 

 light silvery gray, cilia yellowish. Abdomen dark silvery fuscous 

 except third joint, which is velvety yellow above; underside silvery
