Twelve species appear to be uadescribed ; and some of these may 

 belong exclusively to the island ; but our present knowledge of the 

 Coleoptera of the neighbouring continents is not sufficient to enable 

 us to speak with any degree of certainty on this point. Of the pre- 

 viously known species, five have a wide distribution, being found ia 

 Southern Europe and in most parts of Africa : these are Hyphydrus 

 guineensis, Aube, Cybister afrieanus, Laporte, Dineutes cereus, Klug, 

 Temnopterus spinipennis, Guerin, and Epilachna chrysomelina, 01. 

 Two species, Ateuchus sacer, Linn., and Ocnera seiosa, Menetries, 

 are chiefly found in Southern Europe, Asia Minor, and Egypt ; 

 Oxythyrea helente, Schaum, Julodis clouei, Buquet, and Histero- 

 morphtis jdicatus, Kz., occur in Abyssinia ; lastly, Dermestes vul- 

 pinus, Fabr., is cosmopolitan.
