224 THE CANADIAN ENTOMOLOGIST. 



not found any copal trees (Wm. E. Hines, Trans. Anier. Geogr. Soc), or 

 even any signs of any, and to this time it is a mere conjecture in what 

 ages these deposits of copal were made, probably many thousand years 

 ago." I can not give the exact quotation, as I have before me only a 

 manuscript copy of this paper, written before i860.* Some insects out 

 of this copal, called in trade Zanzibar copal, but of the Zanzibar copal 

 which was only exported to East India and not to Europe, seem to be 

 identical with insects living in Ceylon. It can therefore not now be 

 assumed that the Emhidina in copal are still living forms, and that they 

 belong to the fauna of Africa till the identity with living or African insects 

 has been proved. 



Considering that only fifteen living species are described by me, it will be 

 seen that I have been purposely as careful as possible in making new 

 species. I could have enumerated six species more, against which 

 with our actual knowledge little objection could have been made. 

 The type of E. Klugi, in Paris, must be examined to confirm its 

 identity with O. Atricapilla. That of O. Satindersii should be com- 

 pared again with E. Latreillis, with the specimens from Borneo and those 

 collected by Wood-Mason, to make their identity certain. The type of 

 O. Batesii and 0. Brazilie?isis, Burm., should also be compared concerning 

 their identity. The larva from Athens and from Asia Minor could have 

 been given as new species, if it were desirable to describe new species 

 upon such material. Finally the supposition that the large wingless 

 female belongs to O. Michaeli needs the support of further careful obser- 

 vation. 



Of the fifteen living species described, O. Saundersii has by far the 

 largest distribution, Bengal, Borneo, Madagascar, Mauritius and Ascension 

 Islands. O. Insular is, from Sandwich Islands, is, perhaps, to be found 

 in Antigua Island. E. Solieri is not rare in South France and Spain. 

 The other twelve species are only recorded from one locality. From 

 Bengal, O. Michaeli; from Persia, ^5. Persica ; from Africa, ^. Savignyi; 

 from Egypt, O. Nigra; and E. Maiiritanica from Algeria. From 

 America is 0. Ctcbana, from Cuba ; O. Hiibbardi, from Florida ; O. Sal- 

 vini, from Mexico. From South America, O. Braziliensis and O. Rufica- 

 //7/^, the locality not known; O. Batesii from the Amazon ; O. Muelleri, 

 from Santa Catarina, South Brazil.
