BOOK NOTICE. 



Genera Insectorum diriges par P. Wytsman, Coleoptera Adephaga, fam. 

 Carabidse, subfam. Cicindelinpe, von der Walther Horn, 1910. Fasci- 

 cule 82b avec planches, 6-15. 



This, the second part of Dr. Horn's "Cicindelin8e,"has recently come 

 from the press, and is devoted to the platysternale phylum, including the 

 tribes Mantichorini, Megacephalini and Cicindelini. The general plan 

 follows tliat indicated in the review of the first part (vide Canadian 

 Entomologist, 19 to, p. 65), but so many items of interest to American 

 entomologists appear that it seems worth while to notice them in some 

 detail. 



Under Dr. Horn's arrangement, our genera, Amblychila and Omus 

 (together with the South American Fyaiochila), form the subtribe Omina 

 of the tribe Megacephalini. Of Amblychila^ two species are recognized, 

 cylindriformis Say (with the subspecies picolominii Reiche), and baroni 

 Rivers (with the subspecies Schwarzi VV. Horn), the recently described 

 longipes Csy. ranking as a synonym of baroni. In Omus only three 

 species are recognized, dejeani Reiche, submetallicus Horn, and call- 

 fornicus Esch. The first two of these are without synonymy, but the 

 string of names assigned to subspecific or other local forms of calif ortiicus 

 is a long one. Those given specific rank are (i) vandykei W. Horn, (2) 

 audouini Reiche, (3) ambiguus Schpp., {\) punctifrojis (Z%y ., {^) sequoiarum 

 Cr., {6) fraterculus Csy., (7) horni Lee, (8) levis Horn, (9) edwardsi 

 Cr., (10) intermedius Leng, (11) lecontei Horn, (12) fuchsi VV. Horn. 

 This leaves about two dozen of the names applied by LeConte, VV. Horn 

 and Casey with no higher value than that of synonyms. The reviewer is 

 bound to confess that his own series of Omus is too small to throw any 

 light upon the matter. Tetracha, which is made a subgenus of Megace- 

 p/iala, of the subtribe Megacephalina, gets through with no change of 

 name in our two species. The arrangement of the Cicindelini is not 

 completed in this section, but it is divided into two subtribes, only one of 

 which (Cicindelma) is found with us. This has not been reached, but the 

 next part, containing it, will be looked forward to with interest and 

 perhaps with some apprehension by subscribers to the work. 



Something should be said of the plates, which are beautifully 

 executed, and illustrate a large number of exotic forms, as well as a few 

 from North America. As in the preceding part, a good share of the 

 drawings are devoted to structural details. The work as a whole is to be 

 recommended to all naturalists interested in phylogenetic studies, since it 

 represents the views of a writer who considers the insect not as a mere 

 separate entity, but in relation to life as a whole. H. F. VVickham.
