Here we have before us a volume of 248 pages on the Tortricina of 

 Germany and Switzerland, from the pen of Von Heinemann. The 

 work appears carefully and conscientiously written, and contains de- 

 tailed descriptions of 436 species. As the number of species in 

 Wilkinson's ' British Tortrices' is 298, there must be 138 species de- 

 scribed by V. Heinemann which do not belong to the British list ; and 

 we thus get the numerical proportion that the Tortrices of Germany 

 and Switzerland are to the British species as three to two. The pro- 

 portion is probably a little greater, for in many instances we find that 

 where two closely-allied species had been differentiated by the writers 

 in this country, their existence as distinct species is ignored by the 

 writers of Germany. 



V. Heinemann divides the group into ten genera, viz., Teras, Tor- 

 trix, Sciaphila, Cheimatophila, Exapate (which he removes from the 

 Tineina, and places here, following Cheimatophila Tortricella), Olin- 

 dia, Conchylis, Retinia, Grapholitha and Dicrorampha. 



With so few genera a division into sub-genera becomes necessary ; 

 and we accordingly find that Teras is divided into two sub-genera, 

 Rhacodia and Teras. Tortrix is divided into fourteen, Sciaphila into 

 four, Conchylis into four, Grapholitha into twenty, and Dicrorampha 

 into two. But if we thus count all these sub-divisions as genera 

 we only get a total of fifty, whereas in Wilkinson's ' British Tor- 

 trices ' there are seventy-two. 



The arrangement and classification of the group must certainly be 

 a matter of some difficulty, as all recent writers are agreed in differing 

 from each other. 



We should think that this compact volume would have a beneficial 

 effect in Germany and Switzerland in attracting more attention to 

 this perplexing group of insects; but whether it will meet<with a large 

 circle of readers in this country appears somewhat problematical.
