to be referred, so that I have no doubt that it also is a 
plant-eater. Pupation occurred Mar. 5 and emergence 
Mar. 14. 
12. Hypolycaena mgra, Bethune-Baker, sp. n. (p. 502). 
The associated ant was Pheidole aurivillii vr. kasaiensis. 
No. 653, A—I. The ¢ type of the species is G, the 9 
type D. The note referring to these 9 butterflies (8 Q, 
1 3) is as follows :— 
“Feb. 26, 1912. The larvae were all found in the 
forest, 14 miles E., on two adjacent leaves, on Feb. 4. 
I am sure they are all of one company.” ‘The larvae were 
soft, green, and onisciform in shape. Of the numerous 
attendant ants, P. aurivillic kasaiensis, 16 were sent. 
All the larvae pupated Feb. 5; A—E emerged 8 a.m. 
and flew about 9.30 a.m., Feb. 13; F and G (the only 
male), about 8.30 a.m. and flew 10 a.m., Feb. 13; H, 7 a.m., 
and I, before 7 a.m., Feb. 14. 
13. Hypolycaena (Zeltus) lebona, Hew. 
The associated ant was Pheidole aurwillu rv. kasaiensis. 
No. 595. A note of Jan. 18, 1912, refers to a female 
specimen :— 
‘“T am sending a Lycaenid butterfly, with the 8 precise 
ants which were in attendance on its larva. I was able to 
see the dorsal gland in this, but was not sure as to the 
presence of the tubercles. The larva eats the cortex of 
the young shoots, and rarely the upper or lower surface of 
the leaves of the wild ‘ bush-yam’ called ‘Ewo’ in the 
Yoruba tongue.” 
The 8 ants in attendance were P. aurivilli kasamensis. 
The larva was found in the forest 1 mile K., Jan. 4; 
pupation, Jan. 7; emergence, 7 a.m., Jan. 16. 
No. 627. My note referring to a male specimen is as 
follows :— 
“Jan. 29, 1912. The larva of this Lycaenid was deep 
green in colour. The orifice of the dorsal gland was con- 
spicuous, having reddish lips: at the usual site of the 
tubercles were white spots, but I did not see the structures 
protruded.” 
Four P. aurivillii vr. kasaiensis, in attendance, were sent 
with the imago. ‘The larva was found Jan. 12, in the 
forest, 14 miles E.; pupation, Jan. 16; emergence, about 
10 a.m.; flight, 11.45 a.m., Jan. 27.
