486 ANNUAL REPORT OF NEW-YORK 



SUPPLEMENT. 



bristly, as they are in the genus Pieris. It forms the type of a 

 distinct genus, named jyathalis by Boisduval, this species being 

 designated lole. A similar butterfly occurs in the valley of the 

 Mississippi, which, from a specimen received from W. S. Kobert- 

 son, appears to be a distinct species, differing from that of Mexico 

 in havii:g the under side of the fore wings destitute of a blackish 

 central dot, and of the three blackish spots towards their inner 

 angle the hindmost one is here prolonged into a broad stripe 

 extending to the base of the wing and slighly separated from its 

 inner edge; and the base of the wing. instead of its outer margin 

 is orange yellow. I therefore propose for this insect the above 

 name. It is but an inch in width across its spread wings. 



213. Three-colored LiTHOSiA, j^tolmis tricolor, new species. (Lepidoptera. 

 Lithosiidse.) 



The Vermillion-striped Lithosia, L. mmiata^ Kirby, which is the 

 same insect with the Gnophria vittata^ Harris, I have met with in 

 New- York only upon the Highlands of the Hudson. A similar moth, 

 but much less bright in its colors, is commonly confounded with 

 that species, from which it differs in having a large lead-colored 

 spot on the centre of its thorax, the head and also the outer mar- 

 gin of the fore wings, their apical edge, their inner margin and 

 the basal half of the stripe on their middle being nankin yellow 

 instead of bright Vermillion red, and the hind wings are lead- 

 colored on their outer margin nearly or quite to the base. This 

 is not rare in Washington county, and has been sent me from 

 Schoharie by Mr. Lintner, and from Northern Pennsylvania by 

 Dr. G. F. Horton. Its larva feeds upon the lichens or moss grow- 

 ing on the trunks of trees, the moth coming out in July. 



214. Golden Lithosia, Deiopeia aurea, new species. (Lepidoptera. 

 Lithosiidae.) 



A truly elegant little Lithosia, sent me from Savannah, Georgia, 

 by Mrs. Wm. G. Dickson, has the fore wings bright marigold- 

 yellow with four bands of round pale sulphur- yellow spots upon 

 a brilliant steel-blue ground, the hindmost band almost upon the 

 apex, its outer half abruptly widened and slightly united with 

 the third band, which is the broadest, and towards its outer end 

 is abruptly narrowed and almost interrupted. Its hind wings are
