Not seen by the Recorder. A brief notice of the work in Ent. Nachr. 
i. p. 147, suggests that it is extracted from the publications of some

After a general introduction, the author briefly describes various 
common insects of all orders, snails, slugs, Myriopods, &c., injurious to 
fields, pasture land, and gardens in Norway, with notices of their habits. 
The plates, of rather primitive execution, are for the most part bad 
copies of those in Curtis’s ‘ Farm Insects.’ In discussing Vibrio tritici^ 
the author refers to an appearance in the plant called, as he says, in. 
English, “ Peberbrand,” or “ Peberkorn,” the figures illustrating it being 
distinctly those of Curtis. [The Recorder cannot avoid the remark 
that works on economic entomology of this class are worse than useless ; 
general notes, by an incompetent writer, for the most part adopted from 
other authors, badly illustrated, and with the species so disguised as to 
be irrecognizable even by experts, being far more likely to confuse the 
unskilled agriculturist than to direct his own observations in the proper 
channel.]
