THE CANADIAN ENTOMOLOGIST. 107 



Some idea should have been given as to the relative size of Figures 22 and 

 23, and it would appear that Figures 53, 55, 56, 57, 59 and 61 are rather 

 needless repetition of what might well have been illustrated in one or two 

 good photographs. Figure 64 is inverted. Of the mistakes in the letter- 

 press, we notice (p. 64) " the larvae (of Af. domestica) will become fully 

 developed in from eight to fourteen days "; the minimum period for the 

 larval stadium is about five days ; and should not " responds to," on p. 

 82, line 7, be "records"? The seta of the flagellum of the antenna 

 respond to the note, and this response is probably interpreted by the 

 characteristic nerve-end cells in the swollen base of the antenna.

BOOK NOTICES. 



CoLEOPTERORUM Catalogus, pars 23, Cleridse. Sigm. Schenkling, Berlin. 

 W. Junk, Nov., 1910. 



This valuable contribution by the recognized authority on the subject 

 is fully up to the high standard established by the author in his masterly 

 work on the family in the "Genera Insectorum." 



In the first general catalogue of Coleoptera, that of Gemminger and 

 Harold (1869), only 697 species of Cleridae were listed; in Lohde's 

 "Cleridarum Catalogus" (1900), the number was increased to 1,822 ; and 

 in the "Genera Insectorum" (1903), the number recorded was 1,971 

 species, exclusive of 187 varieties, 162 genera being necessary for their 

 reception. In the present "Catalogus" 2,285 species, 224 named varieties 

 and 185 genera are given as valid, the whole making a volume of 174 

 pages, of which 39 are devoted to a comprehensive index. 



The system followed is essentially that of Lacordaire, with numerous 

 modifications and amplifications. The family is primarily divided into 

 two subfamilies — the Clerin^ taking the place of Lacordaire's Clerides 

 vrais, the Corynetin.^ that of his E?iopliides. 



The genera are arranged in natural sequence, while the species are 

 given in alphabetical order. The bibliographical and synonymical refer- 

 ences, both generic and specific, are quite exhaustive, including those of a 

 biologic and anatomic nature, and the general distribution of each species 

 is also given, 



Twenty-seven genera are recognized as members of our fauna, 

 Laricobius Roseahauer being properly omitted from the catalogue, as the
