cocoons, , there were two pigmented and therefore 
nearly mature pupae, lying face to face near the anterior pole 
while the remains of the ant pupa which they had consumed, 
were crowded against the black meconial spot at the posterior 
pole. The other cocoon contained four unpigmented pupae.”

Rhipipallus affinis Bingham. (Rost-Odontomachus ru- 
ficeps coriaria Mayr.)‘‘ sometimes several from one 
cocoon.” (Dodd, 1906). 
Schizaspidia tenuicornis Ashmead. (Jlo^i-Camponotus her- 
culeanus japonicus Mayr) “Occasionally two larvae may be 
found on a single host pupa, and in such instances their position 
is symmetrical with reference to the body of the host.” (Clausen 
1923). 
In all three of the above cases the host pupa is large and 
could easily provide nutriment for two, three or perhaps four 
parasites. But this is not true of the Crematogsater larvae, which 
are only 2.8 millimeters long, and one might wonder whether on 
this ant multiple parasitism is generally successful.
