THE GOLD-BANDED PAPER-MAKER 163

 seven segments of the abdomen and the ab- 

 sence of a sting established the sex beyond 

 question. For several days about as many 

 males appeared as females, but soon there 

 were more males. By the aist of September 

 the Naturalist found that there were more 

 males at the nest than females. As about as 

 many were leaving the nest as were emerging 

 from the cells, the tendency was toward a de-

 an increase. The last larva died on October 3. 

 It was nearly grown, but had apparently not 

 grown any for many days. Apparently, its 

 sisters had fed it just enough to keep it alive, 

 but not sufficient to enable it to complete its 

 development. The Naturalist had not marked 

 the date when it hatched, but it was about the 

 same size as another which hatched on August

 was about fifty days old. At that time there 

 were still a few sealed cells from which the 

 pupae were still to emerge, and one lone female 

 remained at the nest. The season had been so
