A natural history note on the Pseudoneoponera ant-mimicking behaviour of Naddia sp. (Staphylinidae: Staphylininae: Staphylinini: Staphylinina), from Kalyani University campus, Kalyani, Nadia, West Bengal, India.

A unique ant-mimicking behaviour has been observed in the rove beetle genus Naddia sp. (Coleoptera: Staphylinidae: Staphylininae: Staphylinini: Staphylinina) from the campus of the University of Kalyani, Kalyani, Nadia, West Bengal, India. The individual has been observed to undergo imperfect Batesian mimicry by mimicking ants of the genus Pseudoneoponera (Hymenoptera: Formicidae: Ponerinae: Ponerini).

A new species of Endustomus Brme, 1842 and new records of Afrotropical Cossyphini Latreille, 1802 (Coleoptera: Tenebrionidae).

First records of Endustomus nimbaensis Ardoin, 1963 and Cossyphus (Cossyphus) moniliferus moniliferus Chevrolat, 1829 are given for Sierra Leone. New faunistic data are provided for E. parallelogrammus parallelogrammus Fairmaire, 1888, E. senegalensis Laporte de Castelnau, 1833, and E. magnicollis Fairmaire, 1887.
