are laid in the opening buds ; the larva feeds in the flowers until 

 mature, then enters the ground to pupate ; cultivated crucifers are 

 frequently attacked. Phyllopertha horticola (smaller June bug) 

 occurred in a lawn in one district ; the adults attack the leaves and 

 fruit of orchard trees and the leaves and flowers of roses, while the 

 larvae feed on the roots of grass, clover, cabbage and other garden 

 plants. Cabbages were attacked by Baris, Chartophila (Phorbia) 

 brassicae, and Phytomyza flavicornis. Other pests recorded include 

 Ptilvinaria vitis var. ribesiae (woolly currant scale) on Ribes 

 sanguineum, Lytta vesicatoria (blister beetle) on ash, lilac, privet, etc., 

 Cryptorrhynchus lapathi (willow beetle) on willows, Pissodes pini on 

 pines, Myelophilus (Hylurgns) minor in young shoots and under the 

 bark of pine, and the sawfly, Cryptocampus medullarms, Hart. 

 (Etmra pentandrae, Thorn.) in twigs of willow.

 LamelUcorns. — Trans. R. Scottish ArboricuUural Soc, 1916, 

 pp. 50-55, 2 plates. [Reprint received 13th September 1916.] 



Larvae in all stages of development and adults of Sinodendron 

 cylindricum were obtained in Scotland during October from the dead 

 trunks of ash and elm at a distance of from 4 to 10 feet above the 

 ground. This beetle, which is rare in Scotland, has also been found on 

 oak, beech and willow. A related species, Dorcus parallelipipedus, L., 

 has been obtained from broken and decaying stems of ash, elm and 

 walnut. 



The diagnostic characters of the families Lucanidae and Scara- 

 BAEiDAE are given, together with keys to the identification of the 

 adults and larvae of the British species of the Lucanid genera, 

 Sinodendron, Dorcus, and Lucanus, and those of the Scarabaeid 

 genera, Melolontha, Cetonia, and Gnorimus.

 Feeding Habits of the Cotton Stainer in St. Vincent. — Agric. News, 

 Barbados, xv, no. 373, 12th August 1916, p. 267. 



Eriodendron anfracUiosum and Thespesia populnea have been 

 definitely proved to be sources of infection from which Dysdercus 

 delauneyi, Leth. (cotton stainer) can be carried to young cotton fields. 

 In both the Leeward and Windward districts of St. Vincent, cotton 

 was attacked by stainers from these trees and showed a high percentage 

 of internal boll disease during July. Stainers were found during the 

 same month in the vicinity of the trees feeding on seeds disseminated 

 by the wind. The local Government proposes to pass an Ordinance 

 which will enable the Agricultural Department to take such action as 

 may be deemed necessary to control this pest.
