 Gesellschaft (Frankfurt a. M.), xvi, heft i, '90. — "The Lepidopterous 

 Fauna of the Island of Porto Rico," H. B. Moschler, i plate; contains 

 numerous new genera and new species. This is a very useful and im-

IcoNES Ornithopterorum. —A monograph of the Rhopalocerous 

 genus Ornithoptera, or Bird-wing Butterflies by Robert H. F. Rippon; 

 Part I. To be completed in twenty parts, with a map and nearly eighty 

 plates; Part i contains four plates, giving colored figures and the neura- 

 tion of O. urvilliana, hippolytus and crcesus. The text is very exhaustive. 

 If the remaining parts are in the same style as the first, the above will be 

 a grand work.

 with six plates. On the phylogenetic significance of the wing-markings 

 in certain genera of the Nymphalida;, Frederick A. Dixey. Systematic 

 temperature experiments on some Lepidoptera in all their stages, Frederic 

 Merrifield. This paper and the accompanying plates are of great interest, 

 as they show one of the causes of variation in a species, and also teach an 

 important lesson to those who are too hasty in describing new species of 

 Lepidoptera .
