ernment Botanical Gardens, are given. It proved unsuccessful with a 

 beetle on cucumbers, but a complete success in destroying a leaf-hopper, 

 Idiocerus sp., on mango trees and a caterpillar on young orange trees. 

 We are pleased to see that the kerosene emulsion, which we have so 

 strongly recommended for the purpose, has been tried on the coffee scale, 

 Lecaniumviride, and proved eminently successful. Mr. Cotes says: 



From Mr. E. H. Morris's experiments, carried out last year in the Nilgiris, there 

 seemed every probability that kerosene emulsion could be effectively employed 

 against the pest, and information has now been received of its having been success- 

 fully used in Ceylon over a sufficiently large area to test its practical applicability. 



Several pages are then devoted to the life histories of scale insects 

 found on coffee, Lecanium viride, L. coffece, and L. nigrum. 



The publication terminates with a few notes on Khynchota by Mr. E* 

 T. Atkinson. 



Mr. Tryon's Report on the Insect and Fungus Pests of Queensland. — We 

 have just received from the Under Secretary for Agriculture of Queens- 

 land, Australia, a valuable addition to the knowledge of economic ento- 

 mology and botany of that region in a "Report on Insect and Fungus 

 Pests, No. 1 (1889) by Henry Tryon, Assistant Curator of the Queens- 

 land Museum." The work is a pamphlet of 238 pages, and is illustrated 

 with 4 plates showing spraying apparatus. It is to be regretted that 

 no illustrations are given of the pests treated of, and also that the work 

 lacks a good index. It is carefully written, however, and the matter is 

 excellently classified and arranged so that it will be a practical hand- 

 book of the subjects embraced, for orchardists and fruit-growers as well 

 as working entomologists. 



The author first treats the subject in a general way — discussing the 

 relation of soil, state of cultivation and drainage to the increase of in- 

 sect and fungus pests ; the introduction and dissemination of pests, and 

 the necessity of discriminating between friends and foes among insects, 

 together with the protection of insectivorous birds, of which a list is 

 given in an appendix. 



A classified list of the fruits and cultivated plants of the Toowoomba 

 district follows with a statement in connection with each plant of the 

 principal insects and fungi infesting it. Each plant is afterward taken 

 up in order and its various pests discussed at more length. 



Two appendices are added, one relating to insecticide apparatus in 

 which the Riley Nozzle together with certain compound forms is described 

 and figured, and the other being the list of birds already referred to* 

 The author displays a thorough familiarity with the writings of Ameri- 

 can and European entomologists, and in the discussion of many of the 

 cosmopolitan insect pests, or those that are rapidly becoming so, he has 

 quoted largely from the sources named. The similarity of the insect 

 pests of the Toowoomba district with those of America and Europe 

 enables him frequently to use the writings relating to the closely allied
