All INTHOCORID ( Triphleps sp.) 
J. J. Illingworth (152S): The yellow spot disease of 
pineapples is a new trouble, starting about 1326. It 
evidently is a virus disease. So far, I have been unable 
to determine what insect is the vector. Suspicion, at 
■ore sent, rests on this anthocorid bug. It oreys upon plant 
lice on weeds in the field, and is closely associated with 
pineapple plants. 
A BSD SPIDER ( Stjgrraeus floridanus Banks) 
J. ?. Illingworth (1323): Red soiders, Stigmaeus floridanus 
Banks, have been particularly/- troublesome this year in one 
of the dry districts. Practically all of the planting 
material from the tops "as ruined by them. They multiplied 
in tremendous numbers between the imbricated leaves at the 
base of the plant. It has not been oossible to reach them 
in these situations with insecticides. 
QUEENSLAND MITE ( Tarsonemus ananas Tryon) 
J. F. Illingworth (1^23): The Queensland mite is a pest 
of considerable importance. It occurs in the calyx : vity 
of the fruit. The damage is done by opening up wouncs in 
the tubules, found in the floor of the cavity. Organis.-s 
of decay enter through these, causing a considerable break- 
ing down of the fruit. 
A MYCETOPHILID ( Sciara molokaiensis Gri-s'. 
J- F. Illingworth (132S) : y.ycetophilid flies are a serious 
pest in some fields during the winter months. The lar-. 
feed on the new roots of oineapples, hollo-ing out the tips, 
and eating laberals. 
FUTEAPLBD MEALYBUG ( Pseudococcus brevities Cockerell) 
J. F. Illingworth (1923): This - 1 .-bug sorctr-.s c 
a peculiar shotting of pineapple leaves 
This is due to an infection that the bu<~s ret by first I
