Williams (C. B.). The Food of the Mongoose in Trinidad. — Bull. Dept. 

 Agric. Trinidad & Tobago, Trinidad, xvii, no. 4, 1918, pp. 167- 

 186. [Received 28th April 1919.] 



In the course of investigations that have been carried on in Trinidad 

 during recent years upon the control of Tojnaspis saccharina (sugar- 

 cane froghopper), the question of the influence of the mongoose on 

 the abundance of this insect has frequently been raised, it being held 

 by some that the advent of the series of froghopper plagues has 

 closely followed the spread of the mongoose. 



Examination of the stomach contents of the mongoose carried out 

 from October 1917 to September 1918 led to the conclusion that the 

 destruction of lizards, frogs and toads is only partly offset by the 

 numbers of injurious insects destroyed, and there is little doubt that 

 the presence of the mongoose in large numbers in a district will in 

 this way have an unwelcome effect on the numbers of insects present. 

 The chief insects taken as food in order of abundance were : — Grass- 

 hoppers, cockroaches, miscellaneous beetles,|Carabid larvae, Lamellicorn 

 adults and larvae, fly larvae and adult and larval weevils.

The continuation of the investigations on Xylotrechiis quadripes, 

 Chevr. (coffee borer) begun in 1914 is recorded [see this Review, Ser. A, 

 vii, p. 50-54.] There are still many points to be elucidated in the 

 life-history of this Longicorn beetle. The length of the life-cycle 

 has not been determined ; eggs are laid on the stems more or less 

 actively throughout the year, and the author is convinced that the 

 duration of the life-cycle varies according the date of oviposition. 

 Other points as yet undetermined are the natural enemies of the 

 species, the plants other than coffee on which it lives, its geographical 

 distribution, the relative importance of the damage caused by it in 

 various countries of the Far East, the factors which render it unequally 

 injurious in the various regions in which it occurs, etc. The principal 

 experiments carried out are recorded. The life-cycles at various 

 seasons are being determined by placing fresh coffee-plants each month 

 in a cage with adults. Many attempts have been made to discover 

 the various plants and dead wood attractive to the borer. In addition 

 to those mentioned in the previous report, many native plants were 

 tried, but most of them, including bamboo, do not seem suitable 

 for oviposition by X. quadripes. Teak, however, appeared to be as
