tlian 202, the majority of the new forms being either from the 

 Malayan region or from Tropical America, collected by Mr. 

 "Wallace and his former companion Mr. Bates. M. James Thom- 

 son's ' Systema Cerambyeidarum,' a generic synopsis of the 

 Longicorn Beetles by the possessor of the most extensive collection 

 of those insects in existence, also deserves mention here ; likewise 

 the commencement of the Catalogue of Phytophaga by the Eev, 

 Hamlet Clark. Quitting the Coleoptera, we have to notice Dr. 

 Grustav Mayr's memoir on the Formicidse of the voyage of the 

 Novara, which contains a synopsis of the rather numerous genera 

 admitted by that author in the family of the Ants ; and also the 

 commencement of Messrs. C. & E. Felder's account of the 

 Lepidoptera collected on the same voyage, the publication of 

 which was preceded by that of the first part of a complete syno- 

 nymic list of Lepidopterous Insects, by the same authors, in 

 the Yerhandlungen der zoologisch-botanischen Gresellschaft of 

 Vienna. 



Passing to those works which treat only of the insects of 

 particular regions, we must give the first place to two volumes 

 published by Mr. T. V. WoUaston, whose magnificent treatise on 

 the Coleoptera of Madeira is well known. The first of these is a 

 Catalogue of Canarian Coleoptera, published in 1864 by the 

 Trustees of the British Museum ; the second, under the title 

 of " Coleoptera Atlantidum," gives a complete comparative list of 

 the Coleopterous inhabitants of the Madeiran and Canarian 

 groups of islands, which may possibly represent the highest 

 summits of that great submerged continent, or Atlantis, which 

 has been supposed to have been formerly united with the land 

 which now forms Europe. The importance of Mr. Wollaston's 

 investigations into the Coleopterous fauna of these islands is to 

 be found in the fact of the identity or near relationship of most 

 of the Beetles to European forms, — species apparently identical 

 with the latter being found associated with others presenting 

 certain local peculiarities not sufficient for specific distinction, 

 and with others, again, in which the difierences from their con- 

 tmental relations is so great as to induce Mr. "Wollaston to 

 describe them as distinct species, although, in many cases, evi- 

 dently with considerable doubt. Hence it would appear, espe- 

 cially to a partisan of the Darwinian hypothesis, that we have 

 to do in these islands with the remains of a great partially 

 extinct fauna, coincident in many of its forms with that still 

 existing in Europe, but also possessing some peculiar types, the
