of the Amazon Valley. 233 



third elongate spot is orange-red, opake. The hind wing has a very broad 

 dusky-black margin, but the whole disk and the nervures are milky- 

 white. 



The white disk of the hind wing gives this form a peculiar facies. 

 In this character, as well as in the colours of the fore wing, it re- 

 sembles exactly another Ithomia abundant in its locality, viz. /. 

 Ilerdina, Hewits. The two fly together, and cannot be distinguished 

 when on the wing. Ithomia Ilerdina is closely allied to I. Flora. 



9. L. Argochloe, nob. 



c? . Outline of wings same as the preceding. In colours it is extremely 

 like L. Antherke (Hewits. Exot. Butt. Lept. 12) and L. Fortunata (Lucas, 

 Ann. Soc. Ent. Fr. 1854, p. 53. pi. 3), having near the apex of the fore 

 wing a rather broad, oblique, semitransparent white belt ; in all other re- 

 spects it cannot be distinguished from L. Melano'e. It differs from L. 

 Antherke (a Mexican species) in the nervures which cross the white belt 

 being black instead of white. From L. Fortunata (also a Mexican species) 

 it differs in the widely different direction of the red submarginal stripe of 

 the hind wings beneath. In L. Fortunata the stripe is represented as 

 terminating before the apex of the wing, whereas in L. Argochloe, as well 

 as all its allied forms, it curves round within the apex, and nearly or quite 

 meets a similar red subcostal stripe. 



L. Argochloe mimics Ithomia Virginia, Hewits., a species inhabit- 

 ing the same locality, viz. St. Paulo.

 L. Lysinoe, Hewits. Ex. Butt. Lept. 3, 4. — Ega. 



Var. 1. lb. f. 13.— Ega. 



Var. 2. The basal stripe of the fore wing orange-red, opake. The hind 

 wing orange, except the costal margin (which is white in $ , black in 5 )> 

 the apex, a short stripe proceeding therefrom, and a narrow posterior 

 border, which are black. ( $ <$ ) — Ega. 



Var. 3. Syjiilar to var. 1 ; but the basal stripe of the fore wing is also 

 orange-red, and the hind wing is dusky black, leaving a rather narrow 

 orange-red submarginal stripe. ( $ ) — St. Paulo. 



Var. 4. Similar to the type ; but the costal and apical spots of the fore 

 wing are confluent, and the orange submarginal stripe of the hind wing 

 is narrow and abbreviated. ( <$ ) — St. Paulo. 



The typical form is found only at Ega, where also are found vars. 

 1 it 2 ; vars. 3 & 4 occurring only at St. Paulo, in company with the 

 more striking modifications, which I have described above (sp. 6-9) 

 under separate names. The type does not mimic any species of 

 Ithomia of its locality, but it has a most deceptive resemblance to
