in the British Museum. They include some ol the specimens 

 recorded in the table on p. xix. 



In addition to Mr. Neave's captures the following records 

 from S.E. Congo and N.E. Rhodesia have reached me : 



At Tring : Riuwe R., Lualaba Valley, near Katanga, S.E. 

 Congo, 1 ; Fort Rosebery, about midway between L. Bangweolo 

 and the Luapula R., N.E.R., 2. 



At Witley: N.E. Rhodesia, 5; Chambezi R., N.E.R., 5; 

 Katonga R., a tributary of the Upper Chambezi R., N.E. It.. I. 



The Newcastle Museum : .Johnstone Falls, Luapula R., 

 N.E.R., about midway between Mr. Neave's Congo and 

 N.E.R. localities, 2 (formerly in the collection of Dr. II. 

 Elt ringham). 



The Hope Collection. — In addition to Mr. Neave's series a 

 very interesting collection of poggei, its model and co-mimic 

 was presented by Sir Eorace Byatt (Trans. Ent. Soc, 1905, 

 p. 263). The proportions of poggei, chrysippus and misippus 

 in the locality — Kayambi, Awemba Country. N.E.R., near 

 the Chambezi It., 9° 20' S., 31° 50' E., at a height of 3950 ft.— 

 are shown with singular completeness, inasmuch as the 

 insects wexe captured indiscriminately by native schoolboys, 

 collecting, Oct. L898-Jan. L899, for Pere Guilleme. Out of 

 about 1200 butterflies in the collection the following fell into 

 the chrysippus-centred combination : — ■

The proportion of poggei to chrysippus was, therefore about 

 \\ per cent (4*63; the percentage -1"72 is erroneously given in 

 the paper). Sir Horace Byatt's remarks on p. 265 are of 

 much interest in relation to Capt. Carpenter's recent dis- 

 covery. P. poggei " is purely a mimic of chrysippus and 

 shows no approach to dimorphism. This is explicable on the
