■cent, of the cotton capsules are infested. The parasites of this moth 

 mostly attack the larvae, and mclude aBraconid, three Chalcidids, one of 

 which attacks the eggs and the other two the larvae, and a Proctotrupid 

 of which only one female has been observed. It is suggested that 

 immediately after the cotton harvest all bolls remaining on the plants 

 should be collected into large boxes with openings in the sides covered 

 with wire gauze, thus permitting the parasites to escape while retaining 

 the boUworm moths. The boxes should be placed in the plantations at 

 intervals of 150 feet and raised above the soil on stones to prevent the 

 contents becoming damp.

The Elaterid beetle, Agriotes lineatus, L., has recently caused fre- 

 quent and serious damage in nurseries of grafted American vines. 

 The larvae appear towards mid-June, when the tender shoots begin 

 to grow, and attack them close to the point of insertion of the graft, 

 ringing them and pressing and piercing them until they dry up. The 

 damage is gradually reduced as the shoots become stronger. Reme- 

 dial measures as appUed on cereals against this beetle have as yet been 

 unsuccessful in the case of vines.

 1918, pp. 287-297, 5 figs. (Abstract in Mthlg. Bull. Agric. Intell.

Eumarchalia gennadiosi, March., the stages of which are described, 

 oviposits on very young carob fruits in Italy, and the young larvae feed 

 on the fruit tissues, greatly retarding their growth. Sometimes the 

 fruits dry up and fall alter the emergence of the adult fly. There 

 are several generations in a year and both early and late fruits are 

 therefore attacked, the percentage of infestation sometimes rising to 

 50 or 60 per cent. As a remedial measure, all incompletely developed 

 or deformed fruit should be collected, and after storage, can be used 

 as food for cattle. When the tree is attacked by both E. genyiadiosi 

 and by the fungus, Oidium ceratoniae, suitable strengths of calcium 

 polysulphide or sulphur washes should be used.

Moreschiella moricola, subgen. et sp. n., is described, having been 

 found injuring mulberries (Morus alba) in the Province of Teramo, 

 Italy. Eggs are laid in the axils of young branches and the larvae
