Relationship between certain West African Insects. 443 
In addition to the above races, Cremastogasler buchneri, 
For.,? race, is described as associated with the following 
Lycaenidae :—probably Epitola ceraunia (p. 456), EB. carcina 
(p. 456), Argiolaus alcibiades (p. 474), A. gulus (p. 474). 
7. PHEIDOLE ROTUNDATA, For., var. §. 
This form appears in Prof. Forel’s paper under the 
name Pheidole punctulata, Mayr., r. impressifrons, Wasm. 
Prof. Forel, however, informs me that the ant is, in his 
opinion, even closer to P. rotundata, For. r., ilgit. For., 
than it is to P. punctulata. He considers it to be inter- 
mediate between punctulata and rotundala but nearer to 
the latter. This is the principal “ house-ant”’ of Oni, 
although it is also found in the open. Throughout the 
following paper it will be described as P. rotundata, var., 
the name attached to the specimens by Prof. Forel. 
Associated with the following Lycaenids after they had 
been brought home, nearly always replacing ants of other 
species removed at time of capture: Aslauga lamborni + 
and Stictococcus sjdstedti (p. 447); with Myrina subornata 
(p. 472), Hypolycaena philippus (p. 474), Lycaenesthes 
lachares (p. 478), L. flavomaculata (p. 483), Triclema 
lucretilis (p. 485), Catochrysops malathana (p. 488), Oboronia 
punctala (p. 489). 
Associated with the following Lycaenids in the forest 
and clearing: Hypolycaena philippus (p. 474), Lycaenesthes 
lachares (p. 478), N. lyzanius (p. 484), Oboronia punctata 
(p. 489); probably with the Pyralid moth Obtusipalpalis 
saltusalis (p. 492). With the Membracid Leptocentrus 
altifrons (p. 495). 
Attacking and uncertain treatment of the Lycaenid 
Megalopalpus zymna (pp. 463-4). Carrying off eggs of 
Charaxes ussheri (p. 467). Devouring sugar and dead 
insects in the house (p. 491). Attacking and carrying 
off larvae and imagines of the smaller “red house-ant ”’ 
Monomorium pharaonis, L. (p. 491). 
8. PHEIDOLE AURIVILLII, Mayr., r. KASAIENSIS, 
For., $ 
Associated with the Lycaenid Megalopalpus zymna + 
the Jassid Nehela ornata and the Membracids Gargara 
variegata, Anchon relatum, Beninia sp., Leptocentrus alti- 
frons, etc. (pp. 458-468) ; with Hypolycaena nigra (p. 473),
