Mr. II. Drucc on new Species o/Eratina. 97 



XVI. — Descriptions of new Species o/Eratiiia from Tropical 

 South America. By 1Ii:rbl:kt Duucid, F.L.S. &«. 



Latkly having had occasion to arrange tlie genus Eritina 

 and allied groups for the ' Biologia,' I find that I have a large 

 number of undescribed species in my collection from various 

 localities in tropical South America, many of them from 

 Ecuador collected by the late Mr. Buckley, to which are 

 added those received from other collectors during the past few- 

 years. The sjiecies have all been compared with the types in 

 the National Museum and those in the Saunders collection now 

 in the Oxford JMuseum. 



I believe it will be necessary to divide the genus at some 

 future time when more material is available for examination ; 

 but at present many of the species are so rare that it is 

 impossible to do so. 



Eratina artemisia^ sp. n. 



Male. — Primaries dark brown, the basal half the palest ; a 

 curved white band crosses the wing beyond the middle very 

 similar in shape to one crossing the primaries in E, undalata, 

 but considerably wider : secondaries dusky white, broadly 

 bordered with blackish brown, the fringe black, with four 

 white spots on the outer side and one on the inner margin 

 just above the anal angle. The underside of the primaries 

 pale yellowish brown, with the line crossing the wing much 

 more extended, reaching from the costal margin to the inner 

 margin close to the anal angle ; a large silky white patch 

 extends from the base nearly to the white line; a small wiiite 

 line at the end of the cell and a round white spot in the cell 

 nearer the base : secondaries greyish white, irrorated with 

 yellowish-brown scales, the outer margin broadly bordered 

 with yellowish brown ; the fringes as above. The head, 

 antennjB, thorax, and abdomen dark brown, the latter banded 

 with fine white lines, the anal tuft yellow ; the legs, under- 

 side of the thoraXj and abdomen greyish white. 



Female. — Primaries very like those of the male, but shaded 

 with reddish brown on each side of the white line and broadly 

 on the inner margin : the secondaries differ from those of the 

 male in being almost uniformly dusky brown, with a very 

 faint, zigzag, greyish-white line extending from the costal 

 margin to the inner margin. The underside is very similar 

 to the male, but considerably more red in colour.
