Polvbia bistriata: 
Two colonies of this species were collected on Foengoe Eiland on 
February 4. The nests were located within 4 m of one another on the 
undersides of leaves in shaded secondary growth along a path. Both 
were about 1 .5 m above the ground and thus inconspicuous. Several 
adults escaped from each nest. 
The nests were similar in appearance, and of the same shape and 
size as depicted in Figs. 19-21 of Richards and Richards (1951). The 
envelope was whitish-gray with brown streaks, and moderately flex- 
ible. Under high magnification, fragments of plant tissue were dis- 
tinguishable among masticated, somewhat granular material. The 
envelopes were built by the “edge technique” (Jeanne, 1973), and 
were not thickened. They were evidently the products of single con- 
struction efforts, and no growth lines were present. The entrances 
were slightly off-center and ventral, unlike Fig. 19 of Richards and 
Richards but like those described in the text (p. 56).
