 each armed with four sharp teeth. 



The tergites obsoletely wrinkled posteriorly, not spicular, from

Hah. Mergui. A single example from Owen's Island. 



The specimen here described I cannot definitely refer to any 

 known species. The genus Otostigma, however, is exceedingly 

 difficult to understand ; and it is impossible to feel absolute con- 

 fidence in the stability of a species, especially when it is based 

 upon a single example.
