Same yellow ; the apical spots longer and completely confluent, 

 forming a solid patch ; the orange paler ; the bar on arc less rectangular ; 

 broadest on sub-costal ; under side as in the male.

 Arizona, by Mr. O. T. Baron. In all 2 $ and 2 °_ were taken. This is 

 the only known North American species in which both sexes are yellow.

BOOK NOTICE. 



THE BUTTERFLIES OF SOUTH AFRICA. 



South African butterflies : A monograph of the extra-tropical species. By 

 Roland Trimen, F. R. S., etc., assisted by James Henry Bowker, F. 

 Z. S., etc. Vol. I : Nymphalidae ; Vol. II : Erycinidae and Ly- 

 caenidae. London : Trubner & Co., 1887, 8 vo. 



All who have studied foreign butterflies at all are acquainted with 

 Trimen's work on the butterflies of Southern Africa, published more than 

 twenty years ago, under the title Rhopalocera Africae Australis. It will 

 please them to know that there has recently appeared the first two of 

 three volumes on the same subject, which are based, indeed, upon the old, 

 but wholly rewritten, and with a great wealth of additions, especially on 

 the natural history side. These two volumes comprise the Nymphalidae, 

 Erycinidae and Lycaenidae, in all 238 species. The Papilionidae and 

 Hesperidse are to occupy the third volume with about 142 species. It 

 will thus be seen that Mr. Trimen falls into line with all the principal 

 lepidopterists of England in the serial order in which he here places the 

 different families of butterflies, adopting, indeed, exactly the subdivisions 

 and the order Mr. Moore employed in his Lepidoptera of Ceylon, which 

 we noticed lately. But he does more than that; for, in a long introductory 

 chapter of 44 pp.. he treats of the structure, classification and distinctive 

 characters of the groups, together with their geographical distribution, their 

 habits and instances of mimicry in an excellent manner, such as is very 

 unusual in a work of this nature. It would interest every reader of the 

 Canadian Entomologist. So, too, all the families, sub-families and generic 

 groups are characterized with a fulness entirely proportional to the specific 

 descriptions, rendering the work one of the best introductions to a fauna 

 known to me. These descriptions are evidently the work of one who is 

 quite familiar with structure, are not copied from the writings of others, but
