MuTTKOWSKi has given us a Catalogue (1910) of the Odonata 

 of North America. Kellicott, Harvey, Needham, William- 

 son, CuRRiE, HiNE, and Muttkowski have been the principal 

 writers on the dragonflies of the United States, E. M. Walker 

 on those of Canada, the last-named having just published an 

 admirable monograph on the Nearctic Jishnas (1912). 



For Mexico and Central America is the Neuroptera volume 

 of the Biología Centrali-Americana by Calvert (1901-08), the 

 same author having also written extensively (1895-1912) on 

 Neotropical Odonata, but especiall}' on those of the province of 

 Matto Grosso, Brazil. Important papers on South American 

 forms are those of Ris (1904, 1908) and of Förster (1903-1910). 



The last-named has also published much on the Australasian 

 fauna, especially New Guinea, while in AustraHa itself Tillyard 

 (1906-1912) has given us a wealth of interesting observations on 

 habits as well as taxonomic and distributional data. Among the 

 last must be mentioned the discovery in New South Wales of a 

 species of Phyllopetalia, a genus of large dragonflies hitherto 

 known from Chile only ; of the existence of so many species of 

 the Corduliiuce as to amount to two-ninths of the total number 

 credited to this subfamily [sensu Selysii) throughout the world, 

 and representing fourteen genera out of a total of thirty-six. He 

 has also brought forward evidence (1910) that the distribution of 

 AustraHan Odonata on the whole is distinctly adverse to the 

 acceptance of D. S. Jordan's law, viz. : " Given an}^ species in 

 any region, the nearest related species is not to be found in the 

 same region, nor in a remote region, but in a neighbouring district 

 separated from the first by a barrier of some sort, or at least by 

 a belt of country, the breadth of which gives the eft'ect of a 

 barrier." In the Fauna Hawaiiensis, Perkins (1899, 1910) has 

 described the Odonata of these interesting islands. 



In such a survey as this, it is proper to notice the deaths of 

 David S. Kellicott, on April 13th, 1898, and of Francis 

 Le Roy Harvey, on March 6th, 1900, who added much to 

 our knowledge of the Odonata of Ohio and of Maine, respectively. 



We have already alluded to the decease of Baron Edmond 

 DE Selys-Longchamps. Two other entomologists of high repute 

 must be numbered among the Odonatologists who passed away 

 during the period under review — Robert M'Lachlan, who died
