Vili PREFACE. 
Besides the above there were various insect attacks of little 
agricultural interest, though affecting various trades or industries, 
and several only too important, as of Mites, or ‘‘ Red Spider,” 
namely, the Gooseberry. Red Spiders, the Bryobia pretiosa, and 
also the Bryobia ribis (n. sp.), also the Black Currant Gall Mite, 
the Phytoptus ribis, which continues to spread, and the Hay Mite 
and Cheese Mite, respectively the T'yroglyphus longior and T. siro. 
Millepedes of various kinds, especially the Spotted Millepede, 
were, as usual, destructive; and altogether the year was marked 
by much presence of crop infestation; and also, as in previous 
years, there has been enquiry regarding colonial insect attack, 
especially to Sugar Canes. 
I have to express my thanks for much kind assistance from 
colleagues, and for the many liberal presents of valuable ento- 
mological serials, by which I am greatly assisted in my work. 
But amongst the entomological events of the past year, it is 
only a due respect to allude to the loss which all interested in the 
preservation of their crops or fruit have suffered in the decease 
of Dr. C. V. Riley, late Entomologist of the Department of Agri- 
culture of the United States of America, consequently on being 
thrown from his bicycle. Dr. Riley was a countryman of our 
own, and, on his settlement in the United States of America, 
passed some years on a farm, thus laying a foundation of practical 
knowledge for the vast and sound scientific acquirement which 
claims for him the place of the greatest economic entomologist 
the world ever saw. For many years he has used his talents 
unceasingly in gaining, and also in freely imparting, information 
which has been of the utmost service in counteracting not only 
the great infestations of the Continent of America, but for which 
he was the special world-wide referee. In many points we 
benefited much by his assistance in this country; and to myself, 
as to all his friends, his death is the loss of a kind and skilled 
helper. 
In home assistance in‘the past year, in addition to that which 
I have acknowledged accompanying the notes of the different 
infestations in regard to which I have met with much valuable 
aid, I desire to acknowledge very especially the cordial and 
courteous support always accorded both to my work and myself
