The Natural History of the Haliplid^. 



Very little has been written regarding the habits, ecology, etc., 

 of the adult Haliplidse. Schiodte ('6i-'72) has given us rather ex- 

 tensive and detailed descriptions of the larvae and pupae of several 

 species. This small family of aquatic beetles has been neglected 

 although the commoner species are widely distributed, often very 

 abundant, and easily collected. The genera, HaUplus and Peltodytes, 

 occur almost everywhere in small pools, particularly those that are 

 spring feed and contain filamentous alg?e and other aquatic plants.
