The eggmasses were collected in a private residence at Nel- 

 son (Cairns), Queensland, Australia, where the only available 

 food consisted of starch and glue in book bindings, straw 

 used for packing materials, wrapping paper and the like. The 

 residence was used as a laboratory and no food for human 

 consumption was kept about the place nor prepared therein. 

 Another, jet black egg case, longitudinally striate and of an 

 unknown species, rarely found in the same place, averaged 

 about 34 eggs each.
