(122) la. Precis octavia amestris (Driiry)^ 

 Papilio amestris Drury, 1782, 111. Exot. Ent., Ill, p. 26, PI. xx, figs. 3, 4. 

 Precis ajnestris Aurivillius, 1913, Seitz, Gross-Schmett., XIII, p. 224. 



There are tAventy males and eleven females of this, the dry-season 

 form of P. octavia. The}' were all taken at Niangara in November 

 1910, except two of the males, which were caught at Medje in August. 



In the southern and eastern parts of the range of this insect amestris 

 is replaced by the form sesa^nus Trimen, the upper side of the wings of 

 which are much bluer than in this form, and do not have the red spots in 

 the cell of the fore wings, which are always found in the form under con- 

 sideration. We have specimens of P. octavia sesamus from Natal and 

 Mozambique. 



(123) 2. Precis chorimene (Guerin) 



Vanessa chorimene Guerin, 1844, Icon. Regne Anim., Ins., p. 476. 

 Salamis ethyra Feisihamel, 1850, Ann. Soc. Ent. France, (2) VIII, p. 250. 

 Precis chorimene Aurivillius, 1913, Seitz, Gross-Schmett., XIII, p. 220, PL Liib. 



Four males and two females. One male was taken at Faradje, 

 "1911-1912'-'; three at Niangara in November 1910; one female was 

 caught at Pawa, October 19, the other at Niangara on November 25, 

 1910. 



(124) 3. Precis stygia Aurivillius 



Precis ethyra Staudinger, 1883, Exot. Schmett., I, p. 102, PI. xxxviii (non ethyra 



Feisihamel = chorimene Guerin). 

 Precis stygia Aurivillius, 1894, Ent. Tidskr., XV, p. 275; 1898, Rhop. .Ethiop., 



p. 142; 1913, Seitz, Gross-Schmett., XIII, p. 220, PI. Liib. 



This species is represented in the collection by eighty-seven speci- 

 mens. We have several hundreds of other specimens in the Carnegie 

 Museum. It evidently is common where it occurs. The female differs 

 from the male in being lighter in color and broader of wing. The females 

 vary in their markings like the males, of which there are three varieties: 

 P. stygia stygia Aurivillius, the typical form; P. stygia gregorii Butler; 

 and a third, which I believe has not hitherto been described or figured, 

 and to which I apply the name of P. stygia fuscata, new variety. 



iP. aimia Wal'.engren and P. trimeni are near allies of P. octavia (Cram.) and differ from P. anlilope 

 (Feist ham el). The latter species appears to me to be represented by Aurivillius (Seitz, Gross-Schmett., 

 XIII, PI. Lie) by a female of P. trimeni, to which there is a superficial resemblance upon the upper 

 side, but which differs greatly from P. anlilope on the lower side of the wings. I am strongly inclined 

 to think that an unintentional error was committed by the author of the plate to which I make 

 reference. P. aniilope (Feisthamel) falls into the group which I designate as Kallimula.
