the printing, and urges that, in the exceptional circumstances of the case, the 

 delay in distribution should not be permitted to militate against the priority of 

 the newly-described species. This final instalment, it may now be said, is in 

 every way a worthy successor of the eiglit parts of the same monograph which 

 have gone before it, and the author is to be congratulated upon the completion 

 of his magniticent contribution to the literature of the Odonata. 



The completed monograph consists of 1278 quarto pages, embodying a full 

 and authoritative description, written in German, of every S])ecies known at 

 the present time. A new scheme of classification has been adopted, whereby 

 the genera are arranged in ten " groups " of co-ordinate value, beginning with 

 small Old World forms of the Teirathetnis type, and ending with forms, like 

 Puntala and Tramea, having a specialised venation and an expanded anal area 

 in the hind wing. The work is illustrated by 8 coloured plates and 692 text- 

 figures of wing-venation, accessory genitalia, and anal appendages, and is 

 altogether indispensable to every entomologist who desires to study the con- 

 spicuous and beautiful insects included in the LibelhiUnae. Dr. flis's monograph 

 is the third relating to dragonflies so far published iu the Selysian Catalogue, 

 the first and second, by Monsieur Rent? Martin, dealing with the subfamilies 

 Corduliinae and Aeschniiiae, respectively. Two fascicles on the Calopteryginae, 

 likewise by M. Martin, are already in manuscript, and the monographing of 

 other groups is being provided for. 



The foregoing remarks have necessaviW been concerned with the Odonata 

 exclusively, and with the LibelhUinae in particular. Moreover, as dragonflies 

 form the bulk of the collections upon which tbe Selysian Catalogue is based, 

 those insects occupy a commensurate degree of importance in the Catalogue. 

 But it is not to be forgotten that de Selys Longchamps also gathered together 

 much material iu other groups of animals, notably such insects as were formerly 

 included in the old but wholly artificial Order called Neiiroptera. Fascicles 

 dealing with the Embioptera, Plecoptera, Megaloptera, Ascalaphidae, and 

 Trichoptera, for instance, have already appeared, and others on the Mecoptera, 

 and 3Iyrmeleonidae and other Planipeunia are stated to be in the press.
