Besides eommimieatious. or enquiries, sent regarding the 

 above infestations, information was asked about other insect 



troubles — as of Fleas. Auts. and Cockroaches, for instance — of 

 which it was impossible from want ot details and of specimens to 

 tell the species certainly. 



Of crop attacks of other kinds there was again as usual 

 enquiry about " Tuhp-root '* in Oats, which is present every 

 year, though much might be done to prevent it : also of " Onion- 

 bulb Disease,"' and also Bean-stem Disease, caused by the Stem 

 Eelworm, Tylenchus devustatrir. 



Of Mites (Acari. scientifically). Ti/ro^lypkus longiar was re- 

 ported at Ham ; and Phyto-pti i^distiuguishable from other kinds 

 of Mites by their narrow cylindrical shape, and by possessing 

 two pairs only of legs appended near the heail extremity) were 

 also present. Of these, the Pear-blister Mite. Pkyt&ptus pyri 

 eso called from its habit of feeding between the two sides of the 

 leaf, and thus causing blisters), may easily be kept in check; 

 but the Black Currant Gall Mite, P. ribis, continues to cause 

 much mischief. 



I have again added a notice of the " Flatworm,"' Bipalium 

 ketcenst!^ as, by the courtesy of Dr. J. Stewart MacDoogall 

 l^Entomologist of the Royal Botanic Society, Edinburgh), I was 

 favoured with notes of his personal observations of this " Plana- 

 rian,*" feeding on Earthworms, which is an important addition 

 to our former knowledge of the habits of this very peculiar 

 " worm." 



Much communication regarding ordinary insect attacks, and 

 also on co-operation in serviceable ways of spreading knowledge
