NEW MICRO-LEPIDOPTERA. 



BY W. D. KEARFOTT, MONTCLAIR, N. J. 



(Continued from page 9.) 

 Eucosina fuscana, sp. nov. — Expanse, 23 to 30 mm. Head, palpi, 

 thorax and fore wings, brownish-fuscous, finely irrorated with whitish scales; 

 basal area darker, in middle extends two-fifths length of wing. 



Head rough, tuft on second joint of palpi flatly triangular, extending 

 below beyond third joint, latter only exposed from above. Head, palpi 

 and thorax grayish brown or brownish-fuscous, finely and closely irrorated 

 with whitish scales, the tip or outer end of each scale is whitish. Abdo- 

 men whitish-cinereous, anal tuft cinereous, speckled with white. Legs 

 cinereous, speckled with fuscous, fronts of femora and tibi?e of anterior pair 

 brownish-fuscous. 



Fore wing brownish-fuscous, finely and closely irrorated with whitish. 

 The white irrorations are not evenly spread over the entire surface, their 

 absence or partial absence in some places forms darker area ; the most 

 prominent of the dark shade is the basal area, which on the dorsum 

 reaches beyond inner third, thence obliquely and somewhat concave to 

 middle of wing at two-fifths from base, above the middle from base to apex 

 the upper half is evenly irrorated, hence the basal dark area is only 

 sharply defined on the dorsal half of wing. At outer third is a more or 

 less obsolete darker angulated fascia ; from dorsal margin in the form of a 

 narrow bar pointing toward middle of termen, but in length less than one- 

 third the width of wing, directly above it a similar bar reaches to upper 

 edge of cell ; between this outer fascia and dark basal area the white 

 irrorations are thickest, giving the appearance of a paler fascia between 

 these darker shades. Paralleling the termen the white irrorations are 

 arranged in irregular and broken lines. Male costal fold narrow, about 

 one-third length of wing, appressed and darker brown. Cilia same as 

 outer end of wing. 



Hind wing above and beneath, and cilia uniformly pale fuscous. 

 Under side fore vving, same shade of brownish-fuscous as above, but 

 without the paler irrorations. 



Four specimens: Rounthwaite, Manitoba, July, Marmont ; Iowa, 

 Ac. Cat., No. 182, C. P. Gillette; Chicago, Illinois, C. H. Fernald, and 

 one specimen from Prof Fernald, bearing label "10733, Aug. 31," but no 

 locality. 



Co-types in U. S. Nat. Mus., Prof Fernald's and in my collection. 

 In the four specimens before me quite a little variation is observable^
