NEW TORTRICIl) MOTHS— KEARFOTT. 357 



EUCOSMA SOMBREANA, new species. 



Head very pale brown or bleached straw color, palpi brown, speckled 

 with minute paler atoms, tip of third joint not exposed, thorax same 

 as palpi. Forewing- reddish brown, heavily dusted on inner half with 

 cinereous. From middle of costa the cinereous scales form a straight 

 line pointing- to anal angle, but interrupted before middle, then con- 

 tinued to anal angle as golden metallic scales; at angle the metallic 

 line is continued up along the outer margin to its middle, thence 

 inward, and almost meets a spur of the middle line, altogether inclos- 

 ing a vertical ovate section of the red-brown ground color. On costa 

 beyond middle line are six more or less obscure oblique short lines of 

 cinereous, the lower end of each becoming metallic. Entire length of 

 costa cinereous speckled with brown and a preciliate line of the same. 

 There is a very obscure broad paler transverse fascia beyond middle 

 of wing, defined more clearly on the lower half, where it contrasts 

 with a darker shade t)efore it; other specimens are better described 

 by saying that a darker shade rising from inner fourth of dorsum 

 obliquelv toward costa, but on cell coalescing with outer ground 

 color. This dark shade is caused by the absence of the cinereous dots. 

 Male costal fold very wide and three-tifths the length of wing. Cilia 

 fuscous, speckled with whitish. Hind wing dark smok}^ brown, cilia 

 paler, preceded and divided by paler lines. Under side forewing cla}'- 

 brown basal and central part of wing, dull ocherous around edges. Hind 

 wing dull ocherous. In other specimens the ground color of upper 

 side of forewing is darker red- brown, almost purple brown, and the 

 cinereous dusting less in evidence; the under sides of these darker 

 specimens is almost a uniform dark brown, with slightl}" paler cilia. 

 The females seem to be less cinereous and to have more metallic lines 

 on outer half of costa and below apex, but as all before me are rather 

 ))adly rubbed, this may not be true in fresh specimens. 



Abdomen, fuscous mixed with cinereous scales. Legs dull ocherous, 

 tarsi annulated with brown. Eight males, expanse 20 to 25 mm., four 

 females expanse 20 to 23 mm. Tr^^on, North Carolina, Julv 14, Fiske;

1 think the larvae of this species will be found to be a borer in the 

 stems of possibly an aiuuial plant, there seems to be a small race with 

 both males and females about 20 nun., and a large race with both sexes 

 from 23 to 25 mm. This can be accounted for by the supposition that 

 some larvie have lived in small and others in large stems. I would
