xxviii First Repoi^t on Economic Zoology. 



Aiachnida None (?). 



Hexapoda Many insects attack leafage (pea weevils, Sitones), stem 



(Ai)hides), roots (wire-worm or Elatcr larvae), seed 



(pea moth, Grapliolitha pisana), 

 Chilopoda and Diplopoda None. 



Mollusca '. Snails (Helix) and slugs (Limax). 



Reptilia and Amphibia ... None. 



Birds Many of the passerine birds take the seed in the ground ; 



also pigeons, rooks and jackdaws. 

 Mammals Mice take seed in the ground. 



Survey of Sub-section (y) of Section I. 



ANIMALS INJURIOUS TO ROOT CROPS. 



Protozoa to Nemertina . . . None. 



Nematoda None (?). 



Crustacea Woodlice (Onisciis, Ar77mdillidium.). 



Arachnida None (?). 



Chilopoda None. 



Diplopoda Many Jididep, damage roots. 



Hexapoda Large numbers of insects attack root crops (flea beetles 



(Halticidie) ; surface larvae (Noctitge); diamond-back 

 moth (Plntella maculipcnnis) ; root weevils (Ceuto- 

 rhynchus) and Aphides). 



Mollusca Slugs and snails (Liwacid* and BieZicidas). 



Beptilia and Amphibia ... None. 



Birds Many birds eat the seedlings (linnets, sparrows, green- 

 finches, larks). 



Mammalia Rabbits, hares and deer. 



Survey of Sub-section (8) of Section I. 



ANIMALS INJURIOUS TO FORAGE CROPS AND GRASS. 



Protozoa to Nemertina ... None. 



Nematoda Tylenchus devastatrix causes clover sickness. 



Arachnida None. 



Hexapoda Large numbers attack roots (chafer larvae, Melolontlia, 



,«. , Cetonia, leather jackets or larvae of Tipulidie), leaves 



(weevils — Apions),&ni seeds (thrips, midges — Diplosis). 

 Chilopoda and Diplopoda None. 



Mollusca Slugs and snails attack young forage crops. 



Reptilia None. 



Amphibia None. 



Birds The seed of grass, clover, etc., is eaten by sparrows and 



finches. 

 Mammalia Moles cause annoyance in pastures by throwing up hills ; 



gophers in America ; voles and rabbits. 



Survey of Sub-section (c) of Section I. 



ANIMALS INJURIOUS TO FRUIT AND FRUIT TREES, 



Protozoa to Chaetopoda ... None. 



Crustacea Woodlice damage soft fruits (Oniscits, Asellus). 



Arachnida; Various mites (red spider, Tctranychtis and Bryobia) 



damage the leafage. 

 Hexapoda Hosts of insects attack fruit — codling moth, woolly aphis, 



San Jos6 scale, pear midge, mussel scale, bark beetles, 



plum cuculio, fruit flies {Ceratitis), phylloxera. Leafage, 

 • fruit, stem and roots are all subject to insect ravages in 



all parts of the world. 



Chilopoda None. 



Diplopoda Some millepedes (Julidx) damage soft fruits. 



Mollusca Slugs and snails damage soft fruits on the ground.
