hindered by the lack of such a source of reference. There are five plates, 

 four of sexual and other characters and one of an ideal agrotid, 

 showing the normal maculation and habitus, with the proper names for 

 the different constant markings, which will be of great service to 

 students. 



Catalogue of Insects Found in New Jersey, 8vo. Trenton, pp. 486, 

 1890. By John B. Smith. 



The above catalogue is issued by the Geological Survey of New- 

 Jersey and is a publication of much interest. Local lists are of great 

 value when carefully prepared and Prof. Smith seems to have used tin- 

 facilities he possessed to great advantage. Being well acquainted with 

 all the leading Entomologists, both from the public positions he has 

 held, and also as editor of Eatomologica Americana he has been able to 

 avail himself of the assistance of specialists in all the different orders. 

 This catalogue is a valuable contribution to the Science of Entomology 

 in North America, and we trust that ere long many others of the States 

 will follow the good example set by New Jersey. 6,098 species are 

 recorded as occurring in the State. 



Plant Lice and How to Deal with Them, by John B. Smith. 



This is Bulletin No. 72 of the New Jersey Agricultural College 

 Experiment Station. It is a pamphlet of 27 pages and is illustrated 

 with 16 exceptionally good illustrations, all of which are original. The 

 insects treated of are the Wheat Aphis, which, as well as its parasites, 

 is fully described, the Cabbage Aphis, the Black Peach Aphis, the 

 Cherry Aphis and the Melon Aphis. In all cases the best remedies 

 are given and the method of their application is described. For such 

 plant-lice as attack vegetation above the ground, Kerosene Emulsion 

 and Whale-oil Soap are recommended, and for those species which attack 

 the roots, periodical dressings of Kainit of Potash were found effective 

 This substance not only acts as an efficient fertilizer, but also destroys 

 many of the plant-lice. The application should be made just before a 

 rain, if possible, so that the salts can be at once dissolved and carried 

 into the ground. 



This bulletin will be read by many with great interest, and from 

 the language in which it is couched it can be understood by every one.
