KOVITATES ZOOLOGICAE XXVI. 1919. 305 



Butterfly characters : Apex of forewing in male pointed, its uniformly blue 

 patch on the inner margin being slightly variable in shape and extent, but gener- 

 ■ally forming an isosceles triangle. 



Hindwing with four much-elongated and brilliant crimson spots. 



Abdominal sheath much the same as in the former species. 



Forewing of female somewhat thinly scaled in its outer half, a large and 

 rather round white patch marking its centre and partly invading the cell. Hind- 

 wing, like the former, with a regular series of seven red spots. Invariably pink 

 in the fringes of the hindwing of both sexes, but not to any appreciable extent in 

 the forewing of either. 



P. echemon echemon (pi. ii. fig. 7, pi. iii. fig. 3). 



Less common than the last species about Para, but to be obtained apparently 

 at all times of year and in any part of the matto, both sexes of the butterfly 

 occurring along with others of the two groups in paths and glades and at forest 

 flowers. 



The larva has been taken on Aristolochia longicaudata and hurchelli, but 

 more often, like anchises, on A. lanceolatolorata , still further seeming to 

 emphasise the kinship between two caterpillars which are almost identical, and 

 adding to the difficulties of discrimination. See description of the larva of 

 anchises, and compare figures. 



Butterfly characters : Forewing of male much pointed at the apex, with 

 ■outer margin slightly concave, giving it a narrow appearance. Blue patch 

 same as in hjsander, but larger, narrower, and more finely angled at its upper 

 extremity. Hindwing with pink in fringe and four bright red spots. Abdominal 

 sheath entirely dark, with fine long blue-black hair. Patch on forewing of 

 female always below the cell, and, though white and encircled by grey scales 

 in its lower half, is not round like lysander, but triangular or wedge-shaped like 

 its own male. Hindwing with pink in the fringe and six red spots. 



P. neophilus ecbolius (pi. ii. fig. 8, pi. iii. fig. 1). 



This last species of the group, though apparently absent at times, is at others 

 perhaps the most common in certain parts of the matto, such as S. Joaquim, the 

 butterfly occurring in great plenty at flowers of Psychotria colorata. Both ova 

 and larvae have been found sparingly, and always, so far as I can recollect, on 

 Aristolochia hurchelli. The larva is like a small strongly marked edition of 

 lysander, but is of a prettier violet hue with rather more sharply pointed tubercles. 

 These are all deep maroon, except the usual series, as in lysander, which, with the 

 oblique side-stripe in the middle, are lemon-yeUow rather than ochre. The 

 four points above the claspers remain dark. 



Butterfly characters : Forewing of male, like echemon, much pointed at 

 apex and slightly concave on the outer margin. Beyond cell semi-transparent, 

 as though rubbed. An irregular blue-green patch on inner margin culminates 

 above in two or three white and semi-transparent spots. On the hindwing, 

 recalling aeneas, four crimson spots' are enclosed in a magenta patch which 

 ■springs from near the base. Abdominal sheath grey with fine hair. 



I'orewing distinctly fuller in female than male, but also inclining to trans-
