This monograph deahng with the symbiotic relation to the fig 

 of the Hymenoptera concerned in caprification, discusses the mor- 

 phology of these insects, and reviews their history and systematic 

 position. The genus Philotrypesis is described, and the synonymy 

 of all the known species is given.

Rhvacionia [Evetria) buoliana, Schiff. (European pine-shoot moth) 

 is one of the most dangerous Tortricid pests of pines in France. As 

 a rule the flight-period occurs at the end of June and in July, and the 

 eggs are laid in August on the terminal shoots of young pine. The 

 larva hatches early in autumn, and hibernates in a resin-covcred 

 groove on the shoot. It feeds in the following year from April to June, 

 and pupates in the shoot at the end of May or in June. 



R. buoliana appears to be a native of Central Europe. Various 

 records of its injury in Europe and North America are mentioned. 

 In France serious damage is done, especially in the Bordeaux region, 

 and the injury is enhanced by that of an allied species, R. turionana. 

 Pinus sylvestris is principally attacked, but P. strobus, P. resinosa, 

 P. laricio, P. montana, etc., also suffer. In America the infestation 

 began on P. laricis var. austriaca and P. montana var. mughus at the 

 same time as on P. sylvestris imported from Europe. Trees from 

 6 to 15 years of age suffer most. 



To prevent infestation Barbey has recommended the avoidance of 

 unmixed plantations of pine in all cases where the soil permits the 

 growth of other trees. Once infestation has begun the sole remedy 

 consists in collecting the infested shoots, which should be burned or 

 placed in receptacles permitting the escape of Hymenopterous parasites. 

 The latter include Pristomerus vulnerator, Panz., Cremastus interruptor, 

 Grav., Orgilns obscurator, Nees, Ichneumon fugitivus, Grav., Pirnpla 

 nificornis, Grav., Lissonota buolianae, Hrt., Triclistus curvator, ¥., 

 Cremastus confluens, Grav., C. decoratus, Grav., Exetastes cinctipes, 

 Retz., Limneriun geniculatum, Grav., L. albidum, Gml., Bracon 

 discoideus, Wsm., Chelomis sulcatus, Jur., Perilampus laevifrons, Dalm., 

 and Habritys brevicornis, Ratz. Some predatory insects and birds 

 also help to check this pest.

From the Lyons district two new parasites of Picris brassicae are 



recorded. Drosophila rubrostriata. Beck., was brought from the 



Canary Islands on bananas and has readily become acclimatised. The 



flies live on organic vegetable or animal matter in decomposition ; 



parasitism of insect larvae has not hitherto been recorded.
