Description of the mature larva and pupa of Ora semibrunnea Pic (Coleoptera: Scirtidae) with notes on its biology.

In this paper we describe and illustrate for the first time the immature forms (larva and pupa) of Ora semibrunnea Pic, 1922, including biological information and behavior observed in the laboratory. This is the first record of the occurrence of this species in the Brazilian Amazon region. Larvae and pupae were found in natural lakes associated with macrophyte banks.

Redescriptions of Scirtidae (Coleoptera: Scirtoidea) described by Carl Henrik Boheman (1796-1868) with notes on Scirtes adustus iversenotatus Pic, 1930.

Boheman described four species of Scirtidae: one from Sweden (Cyphon pallidulus Boheman, 1850), two from South Africa (Elodes caffer Boheman, 1851 & Elodes marginipennis Boheman, 1851), and one from Argentina (Scirtes adustus Boheman, 1858). Cyphon pallidulus Boheman is a junior synonym of Contacyphon ochraceus (Stephens, 1830). Types of the remaining species were never re-examined, and none of them were redescribed.
