Relationship between certain West African Insects. 471 
Perhaps the position is reversed, and it is the larva that 
provides the ants with food, possibly buccal secretion or 
regurgitated material, since it has no dorsal gland. When 
I first had the larva it did not feed, as far as I could see, 
for 24 hours unless the ants gave it food, but it then ate 
a number of the Jassids. I imagine that these carnivorous 
larvae when they find a colony of food-insects have to 
make as big a meal as they can so as to be prepared against 
a possibly long wait before they find others. 
No. 692 B, 9. The larva was found in the forest 
4 mile E., on Mar. 3, and pupated on Mar. 7, 1912. “It 
ate the same food-insect as larva A, and they were attended 
by the same ants.” 
No. 692 C, 9. The larva was found in the forest 
3 mile E., on Mar. 7, and pupated on Mar. 11. “It ate 
the same Jassids as larva A, and the same ants were in 
attendance on them.” 
Pupation of A, Mar.1; B, Mar.7; C, Mar. 11; emergence 
of A. Taan., War. 10-? B,’ Mar. 16°C: “Mar.’20. 
The Jassids, O. bicolor, were in each case found on similar 
food-plants, as yet undetermined. Nine mature and 17 
immature Jassids in various stages were sent, together with 
11 § minor and 2 § major C. akwapimensis v. poultoni— 
both Jassids and ants collected in the forest near Oni 
Clearing, Mar. 7, 1912. One % major is the type of the 
variety. Five of the larval Jassids are different from the 
others and may perhaps be Nehela ornata.

sp. n. (p. 501). 
The associated ant was Cremastogaster buchneri r. 
alligatrix. 
No. 796. The larvae of the 2 male butterflies under this 
number were soft-bodied vegetable feeders. The note, 
May 26, 1912, runs: ‘“‘ The larvae of these 2 Lycaenids 
were found in the forest 14 miles E., on May 4, 1912. They 
were attended by a large number of ants, but I did not 
discover the source of attraction to them, for, as far as I 
could see, neither gland nor tubercles were present. 
“The butterflies were new to me but may have been 
confused with others.” Fourteen ants were in attendance. 
Pupation, May 9; emergence, May 16.
