KIRKALDY'S CATALOGUE OK THE HEMIPTERA. An appreciation with di- 

 gressions.* 



The appearance of volume I of Mr. Kirkaldy's Catalogue of the 

 Hemiptera of the world marks an epoch in the study of this group of 

 insects, not alone on account of the quantitative enumeration of the 

 described forms but even more for the foundation it gives us for an 

 up-to-date classification of our Hemiptera. I have ventured to criticise 

 a few features of this catalogue, but I do so no? to find fault with a 

 work which is of the highest quality, but as a conservative in matters 

 nomenclatural, I believe a catalogue of this kind should not represent 

 the extreme views of a radical. However, this is but my private opin- 

 ion and I am well aware that most of our students may prefer the 

 sweeping changes here proposed. 



Of. greatest interest are the forty pages of introductory matter be- 

 ginning with a complete but succinct statement of the rules of nomen- 

 clature followed by the author. If we cannot agree with all his con- 

 clusions we must admit that he has led us a long way toward a stalilr 

 nomenclature in this order. Following this is a discussion of the classi- 

 fication adopted, a partial Bibliography, an incomplete list of abbrevia- 

 tions and an appendix giving the author's reason for the selection he 

 has made of types for many of the genera, an item of much importance. 



The catalogue proper occupies 361 pages and embraces the family 

 Cimicidae (Pentatomidae) only. It covers the same ground as volume 

 I of the Lethierry and Severin Catalogue, except that the Thyreucori- 

 dae (Cydnidae) and Urolabididae are relegated to the second volume, 

 an unfortunate, although doubtless necessary procedure. Following this 

 catalogue are 23 pages of additions and corrections bringing the list 

 down to the end of 1907, and including most names published in 1908 

 and 1909. At the end is an index to genera, the specific index being 

 held for the second volume.

 tomical references, lists of food plants and parasites, etc. Prefaced by
