and the opening of the sericteries ; the latter a short trans- 
verse slit in an anteroventral depression. Dorsal portion 
of the hypopharynx with sublongitudinal ridges, ventral 
portion spinulose, the spinules minute and in numerous 
subtransverse rows. (Material studied: six larvae from 
the nest cited above.)

do not know whether it differs as much from its congeners 
as does its adult. It does, however, resemble the larva of 
the closely related genus Novomessor.
