Since the two colonies were of about the same size the 
workers in each averaged about 115 and were therefore 
only a ninth or a twelfth as numerous as in the two well- 
developed sumichrasti colonies observed by Dr. Skwarra. 
(2) Closer scrutiny of the preceding table yields even 
firmer support for the contention that the wingless males 
and females are parasites, because in genera of workerless 
parasites, of which Wheeleriella and Anergates may be 
regarded as typical, the host queen is assassinated either by 
her own workers or by the intrusive queen and the brood of 
the host species is therefore lacking. It will be seen from 
the table that there were only one pupal and six callow 
workers in the two colonies. Of the 60 larvae and semipupae 
mentioned at the end of the list, the semipupae, which num- 
bered 36, are undoubtedly, and the 24 larvae, which are too 
small to exhibit sexual characters, are very probably all or 
mostly males. Of the four adult females, three were taken 
from the colony near Panajachel, and one from the colony 
near Tsanjuyo. The latter, in all probability, is the original 
mother of all the larval, callow and adult sexual forms of 
that colony, but whether the other colony contained three 
mother queens or whether two of them were her mature 
daughters cannot be determined, owing to their equally deep 
pigmentation and complete aptery. Dr. Skwarra’s observa- 
tions on the pronounced pleometrotic proclivities of the typi- 
cal sumichrasti suggest that all three queens may have been 
the mothers of the males, females and brood of the colony 
near Panajachel.
