EUCOSMA MINUTANA, new species. 



Face and palpi cinereous, tuft on second joint outwardly rounded, 

 third joint concealed; top of head, thorax, and forewing dark gray, 

 minutel}' and closeh^ dotted with cinereous. An oblique paler shade, 

 from inner third of dorsal maroin, defines the basal area; the line of 

 demarcation is sinuate, with tliree outward and two inward indenta- 

 tions to middle of wing, where it disappears. Ocellic spot small, 

 rounded, cream white, with a black horizontal dash about its middle 

 which cuts through its outer side; another black dash on the upper 

 edge, immediateh' above the lower. These two black dashes are so 

 arranged that, under a glass, the white ocellic spot has the appear- 

 ance of a compressed interrogation mark, or comma laid on its side, 

 with the straight end pointing to the outer margin. Several other 

 black dots partly surround the white spot — one, a dash, before it, and 

 above the dash a smaller dot; another vertical dash defines the outer 

 end of the conmia. The costa — from inner third to apex — is marked 

 with gradually increasing in size triangular oblique dark-brown 

 dashes, each edged with cream white, irregularly arranged as four sets 

 of geminate spots. The apical spot is cream white, divided by brown 

 line; the costal spot before the apical sends a long, dark-bluish line 

 obliquely to outer margin, then turns downward to top of ocellic spot, 

 whei-e it unites with a similar line out of apex. Cilia same as ground 

 color, and with the space beyond the ocellic and subapical marginal 

 lines forming quite a wide marginal band. Hind wing and cilia smoky 

 brown, a shade paler beneath. Underside forewing dark brown, with 

 whitish marks repeated on costa. A))domen and legs gray, speckled 

 with light brown, tarsi annulated with cinereous. Expanse, 9 to 

 14 mm. About forty specimens. Try on, North Carolina, May 24-25,

 Merrick^s, and my own collection. 



I have long had these specimens mixed with K strenuana Walker, 

 which it is superficially much like, excepting very much smaller 

 size. But, in addition to the size, it can be separated by grayer 

 ground color, ditlercnce in ocellic spot, and arrangement of costal 

 spots. Structurally, the forewings are more than three times as long 

 as wide, much wayvowqv iXvAw strrmnoxt-'^ The outer margin of fore- 

 wing of both species is sinuate, thus difiering from E. drciihina^ which 

 is the type of the genus; and therefore when this cumbersome genus 

 is divided, both of these species will fall into a ditferent genus.
