of the Amazon Volley. 231 



The true AmpJiione of Cramer I did not meet with on the Amazons ; 

 but at Ega, on the upper river, the present well-marked local form 

 occurred. It is a species which offers, in other countries of Tropical 

 America, several more or less strongly-marked varieties, many of 

 which have been described, without mention of the relationship, as 

 distinct species. The Ega form flies in company "with the Ega var. of 

 Mechanitis Polymnia, viz. M. Egaensis, audit is difficult to distinguish 

 the two species on the wing. It is well worthy of remark that the 

 S.E. Brazilian form, L. Astyoclie, also adopts the livery of Mechanitis 

 Niscm, the local form of M. Polymnia of the same district. 



3. L. Tapajona, nob. 



P. Lata, Cram. 232 c. d., local var. 



5 . Differs from L. Laia in having the costal stripe of the fore wing 

 and the first macular belt attached thereto of the same yellow colour as 

 the second or subapical macular belt. 



I did not meet with the true Laia in the Amazon region. L. 

 Tapajona occurred only on the banks of the Cupari, an affluent of the 

 Tapajos, in 3° 40' S. lat. 



4. L. Lysianax, Hewits. 

 L. Lysianax, Hewits. Exot. Butt. Lept. f. 19 *. 



This is another local form of L. Laia. In the colour of the costal 

 stripe and the belt of the fore wing it resembles L. Tapajona, but 

 the belt is not interrupted as in that subspecies : it wants, however, 

 the yellow apical belt, at least on the upper side ; beneath, it exists 

 as " three small white spots." If this insect were taken really 

 within the Amazon region, it must have been at Pebas or Nauta, on 

 the upper river. 



5. L. Theonoe, Hewits. 

 Z. Tlieonoe, Hewits. Exot. Butt. Lept. 2. 5. 



Found on the banks of the Cupari, an affluent of the Tapajos, in 

 company with Ithomia Flora, with which it has a striking mimetic 

 analogy ; it was exceedingly rare, whilst the Ithomia was very 

 abundant. On the Upper Amazons Theonoe did not occnr, nor 

 Ithomia Flora, but in their stead a number of species of Ithomia 



* L. Lycosura, Hewits., represented on the same plate, f. 18, 20, I suspect does 

 not belong to the Amazonian fauna. M. de Gand, who supplied these insects, 

 collected more at Moyobamba, on the eastern chain of the Andes, than in the 

 Amazon valley, but unfortunately his collections from different parts were mixed 

 together.
