green with or without Bordeaux mixture or Hme-sulphur was effec- 

 tive against them. Contarinia {Cecidomyia) nigra was somewhat 

 injurious in Jutland, but Perrisia (C.) pyri was observed in only 

 one locality. Paratetranyckus pilosus and Eriophyes pyri also 

 occurred. 



Pests of stone fruits included Eriocampoides limacina, Hoplocampa 

 fulvicornis, Argyresthia ephippieUa, Lyonetia clerkeUa, Cheimatobia 

 hriimata, C. horeata, Diloba coerideocephala, Eidecanium {Lecanium) 

 corni, and the Aphids, Hyalopterus pruni, Phorodon humuli and 

 Anuraphis [Brachycaudtis] helichrysi in immense numbers on plums. 

 Myziis (Myzoides) persicae occurred on peaches and M . cerasi on cherries. 

 Tobacco extract was of only limited value against the Aphids. 



On raspberries were recorded Otiorrhynchus picipes, Bytiints tomen- 

 fosus, Incurvaria rubiella, Pennisetia (Bembecia) hylaeiformis and 

 Aphids. Pests of gooseberries, currants and black currants included 

 Capsids, Aphids, especially Eriosoma (Aphis) grossulariae and Rhopa- 

 losiphiim ribis mainly on black currants and Eriosoma {ScJiizonciira) 

 fodiens on the roots of currants, Otiorrhynchus picipes on currants, 

 sawfly larvae, perhaps those of Pteronus ribesii, common on goose- 

 berries, and Eriophyes ribis on black currants everywhere. 



On hazel, an Aphid, Callipterus coryli, and a mite, Eriophyes 

 avellanae, were recorded. 



Strawberries were attacked by Capsids, Goriyna micacea, Tar- 

 sonemiis fragariae and Antlionomus ritbi On melons Aphis gossypii 

 appeared in one locality in such numbers that all the plants died. 

 Acrolepia assectella did damage to leeks and Hylemyia aniiqiia lo 

 onions. 



Crioceris merdigera was very injurious to lilies in one locality, and 

 roses were commonly attacked by Typhlocyba rosae, Aphis rcsae, 

 Blennocampa aethiops, B. pusilla, ancl especially Ardis bipunciata. 

 On lilac and privet the mines of Gracilaria {Xanihospilapteryx) 

 syringella were commonly met with. Perrisia {Cecidomyia) affinis 

 damaged violets, and Phytomyza affinis infested cultivated 

 chrysanthemums. 



The general pests recorded were Agriotes lineatits, Tipida paludosa 

 and other species of Tipiila, which were very injurious ; Forficida 

 aiiricnlaria, Melolontha melolontha (vulgaris), Phylloperiha horticola and 

 Eiixoa (Agrotis) segetum were of less importance.

Various opinions have been held as to whether Silvanus surinamensis, 

 L., is carnivorous and useful as an enemy of Calandra (Sitophilus) 

 granaria, or a grain-feeder and, therefore, injurious. Nearly all 

 records of injury to grain and of annoyance to the inmates of dwellings 

 come from America and Hungary. In Hungary' it occurs together 

 with C. granaria, the presence of which is encouraged b)' storage of 

 grain in unsuitable buildings. Scarcity of food compels the migration 

 of both beetles. Such migration in the case of S. surinamensis occurs 

 in the second half of the year or in the early winter months. There 

 seems to be but one generation. The egg, larva and pupa are found
