TMs Coccid which has been recorded prcAaously from Devon, Surrey, 

 Cheshire, Durham and Yorkshire is repoi-ted as occurring in extreme 

 abundance on every Cleveland moor visited, as well as on the fells on 

 the Northumberland-Cxmiberland border, and in the far west of 

 Durham on Erica tetralix, far from its lowland habitat.

The destruction of acres of white turnip near Wakefield by the 

 larvae of Euxoa {Agrotis) segetum, Schiff., is reported by Mr. Hooper. 

 Mr. Morley commented on the swarms ohCharaeas graminis, L. [see 

 this Revietv, Ser. A, v, pp. 478, 481] in August on both moors and 

 lowland pastures, these larvae having been such a pest in South-west 

 Yorkshire, that at Penistone the town-roller was mobilised to deal 

 with the invasion.

Although much has been done to help farmers in their campaign 

 against insect pests, by the publication of spray calendars and of 

 information regarding the life-histories of the chief economic insects,, 

 yet most valuable help might be obtained by each farmer in studying 

 such common pests as Epochra canadensis (currant fruit fly). By 

 collecting and burying injured fruit in the spring, erecting a closed 

 lantern chinmey over the spot and watching the emergence, it would 

 be possible to ascertain exactly when to apply the poison-bait spray, 

 in each individual case. Similarly the common and widely distributed 

 Lepidosaphes ulmi (oyster scale) could be sprayed for most efficiently 

 if the farmer were able to ascertain the time of hatching by the first 

 appearance of young scales upon the bark. Insects that emerge from 

 the soil in the early spring, such as pear-thrips [TaeniotJirips inconse- 

 quetis], could be controlled if their emergence w^ere observed in small 

 cheese-cloth cages erected on the orchard soil. In the same way in the 

 case of the cabbage-root maggot [CJiortophila brassicae], the best time 

 for applying mixtures to the roots or erecting cheese-cloth screens over 

 the early radish crops could be determined by burying a few maggots 

 from autumn cauliflowers in 2 or 3 inches of soil, and noting the date 

 of emergence of the flies in spring. Insects that winter above ground 

 on twigs or branches may be kept under observation by bagging the 

 twigs with cheese-cloth.

The larva of a moth, Ballovia cistipennis, a new pest of cowpeas, 

 has appeared in St. Vincent, having been previously recorded from 

 Barbados. The eggs are laid at the top of the flower-stalk or in the
