The author expresses his agreement with the views stated in a paper 

 by Dr. L. 0. Howard [R.A.E., A, iii, 353], and explains his reasons 

 for claiming an independent and authoritative position for applied 

 entomology. Some of these have already been noticed [R.A.E., A, 

 ix, 158].

Except as regards forestry, the official scientific plant protection 

 service in Germany has been directed by botanists and, sometimes, by 

 chemists ; zoologists have only held subordinate positions. The view 

 here expressed is that botanists, even applied botanists, have no claim 

 whatever to be consulted as regards the training of the applied 

 zoologist. The latter needs a thorough knowledge of zoology, 

 especially entomology in all its aspects, and such a knowledge absolutely 

 outweighs a preliminary knowledge of botany and agriculture, though 

 , the latter subjects are naturally desirable. The ideal training would 

 comprise a thorough knowledge of zoology, then chemistry and botany. 

 During or after these studies, lectures on applied zoology and agri- 

 culture in general should be taken at an agricultural college. This 

 should be followed by a summer's practical work on a large agricultural 

 or horticultural estate.

[Plant Protection at the Munich High Schools.] — Zeitschr. angew. 

 Ent., Berlin, vii, no. 2, February 1921, pp. 450-452. 



The methods of teaching applied zoology followed at the University 

 and Technical College at Munich are briefly described. The lectures 

 on forest entomology lay stress on the relation between forestry, soil, 

 climate, etc., and the occurrence of pests, attention being given to 

 natural enemies. The lectures are supplemented by practical work, 

 including identification of insects and excursions into forests. 



Since 1917, lectures on the animal pests of agriculture have been 

 given, and recently the training on agricultural plant protection has 

 been made similar to that already existing for forest protection.

Ent., Berlin, vii, no. 2, February 1921, pp. 453-456. 



In recent years several cases of injur}- to peach foliage by Leptophyes 

 pnnctatissima, Bosc, have occurred in North Germany. This Orthop- 

 teron has been frequently recorded in South Germany, whence it has 

 apparently been introduced into the north. As only an imperfect 

 description is available, the species is redescribed. 



L. punctatissima was found in Jul}', August and September, .the 

 younger larval stages having escaped notice at the beginning of
