of children by these very peculiar beetles. Whether they enter by the mouth as an egg and undergo development into larva and pupa and finally into the adult beetle within the intestines, or whether they enter per rectum while children defecate in the open is not certain. Senior-White was the first to note that Onthophagus bifasciatus. Fb. (Copridae) infested the intestines. I have since observe...

Walker's Eleodes (Coleoptera: Tenebrionidae).

The type specimens of five species of Eleodes described by Francis Walker from British Columbia, Canada, were studied in order to establish their true identity. The synonymy of Eleodes convexicollis Walker and E. conjunctus Walker with E. obscurus (Say); that of Eleodes latiusculus Walker with E. humeralis LeConte;  and that of Eleodes binotatus Walker with  Eleodes hispilabris (Say) is confirm...

Parental RNAi in Tribolium (Coleoptera)

RNA interference (RNAi) allows for rapid and straightforward analysis of gene function. RNAi can be applied with special ease in Caenorhabditis elegans where injection of dsRNA into the body cavity or application of dsRNA via ingestion leads to gene inactivation in offspring embryos [1,2]. This parental RNAi effect made possible efficient genome-wide functional screens in this organism [3]. Her...
