This paper describes Metamasius ritchiei, sp. n., a large black ■vreevil 

 which has been found doing serious damage to pine-apples in Jamaica. 



[There is reason to suppose that the species has been introduced 

 from South America. — Ed.]

 Forest. — Scottish Naturalist, Edinburgh, no. 59, November 1916, 

 pp. 275-281, 3 figs. 



Three species belonging to the genus Hylastes are of economic 

 importance in Scotland, yiz:—H. ater, Pk., H. palUatiis, Gyl., and 

 H. cunicularius, Er. Observations on the last-named, made in 

 Aberdeenshire and Peeblesshire, show that it lives in the larval stage 

 in the roots of spruce, preferably in those from | to 2 inches in diameter, 

 a short distance below the surface of the soil. The larval galleries 

 ultimately form a large cavity, from which pupation chambers arise 

 at intervals. The adults on emergence are sexually immature and 

 attack young conifers just below the root-collar, where they girdle the 

 stem, prevent the sap-flow and cause the death of the tree. This 

 species is often accompanied by Hylohius abietis, L., which injures the 

 tree above the level of the ground. In areas under observation the 

 loss caused by the adults of H. cunicularius was not less than £1 per 

 acre, reckoning the cost of planting at £3 per acre. As a preventive 

 measure, the burning of brushwood on the tops of stumps may be of 

 value if carried out just before or during the egg-laying period in April 

 or Mav.

A method suggested for trapping the fruit-fly [Ceratiiis capitata) 

 consists of hanging in the fruit trees pieces of board or tin painted 

 with luminous paint and then covered with some adhesive substance.

Attention is drawn in this article to the value of poison bait for 

 controUing Lepidiotu albohirta [see this Review, Ser. A, iv, p. 470].

 Field observations regarding insects predaceous on the minor pests 

 of sugar-cane have led to the discovery of a small arboreal earwig, 

 probably a species of Labia, which is evidently an important enemy of 

 Aphis sacchari, L. This earwig frequents cane-fields in the vicinity of 

 Gordonvale at all times of the year.
