278 THE entomologist's recokd. 



hybr. iitterfainiitti, a cross between a (J of the American asti/lim and a 

 5 of the European ocrllata ; of Sincrinthiis hybr. oberthiiri, of ^'. 

 hybr. frinr/si, Amorpha hybr. vii'tis, and A. hybr. inversa, are full of 

 interest, whilst on pp. 291-294 are the details of numerous Attacid 

 crossin,ns, and on pp. 296-304 a full summary of the crossings of the 

 allied European Saturnians ; there is no need to state that fvill accounts 

 of the crossing experiments of Lasun-ainpa (jui'iciis and its various races 

 are also given. The details relating to gynandromorphs are most 

 interesting. Scarcely a species that is here treated but has given 

 some examples, and when one notes no fewer than 32 gynandromorphs 

 of Lasiocampa qaercua described, 60 of Satiiniia pavonia and 85 of 

 Amorpha populi, besides smaller numbers of the other species, the 

 biologist will recognise that he has here an abundance of material on 

 which to work. The British collector will turn with the greatest satis- 

 faction to Chapman's comparison of the life-histories of Aiiiorjiha 

 populi, Mimas tiliae and Smcrinthtts ticdlata, and the author's grouping 

 of the Amorphids should at least flatter the vanity of the City of 

 London Entomological Society, which one knows he loves so well. 

 The names of Messrs. Sich, Burrows, Kaye, Dadd, Bell, Nicholson, 

 and Clark are all laid under contribution for new genera, and no doubt 

 other members names are only missing because they have been 

 previously utilised. 



To the systematist there are four chapters that will require time, 

 thought and digestion. Firstly, the account of the family Kntricliidav 

 (pp. 111-123). Secondly, the study of the position of DimorpJia [Kn- 

 (Jrovris) (pp. 229-236). Thirdly, the classification of the Attacides, a 

 detailed account of all the work done in this direction (pp. 265-290) ; 

 and lastly, the exhaustive chapter on the literature, synonymy and 

 classification of the Sphingides (pp. 342-382). Much internal evidence 

 shows that the author hopes to attract criticism on this part of his 

 work, and his preface tends also to point in the same direction. As 

 to this, the final conclusion of the author on the actual types of the 

 genera he uses may be worth quoting. These read (p. 355) : — ■
