INJURIOUS AND BENEFICIAL INSECTS FOUND ON THE 

 ORANGE TREES OF FLORIDA. 



BY WM. H. ASHMEAD, JACKSONVILLE, FLORIDA. 



Since my discovery of the mite found preying upon the eggs of the 

 Orange Scale Insect ( Aspidiotns Gloverii), I have been studying the 

 insects found on the Orange tree, and my study has resulted in bringing 

 to light many curious insects, of which I submit the following brief 

 description. Those interested will find a full account of their habits in 

 the Florida Agriculturist. 



Glovet's White or Yellow Orange Mite. 



Acarus f Gloverii, n. sj>. — Soft, flattened, oval, of a pale yellow color, 

 with a broad pinkish flesh-colored stripe extending from thorax down the 

 middle of abdomen, terminating at hinder edge, which is obtuse ; legs 

 eight, thin, finely pubescent, with two claws. Length about .01 of an 

 inch. In company with them are often seen pale flesh-colored specimens, 

 which are the unmatured ones. 



I find it mentioned by Townend Glover in an old Agricultural Report 

 published in 1855. It seems pretty widely distributed through Florida 

 and is found in company with the Oval Scale Insect (Aspidiotus citricola) 

 on the eggs of which it probably feeds. 



Aphelinus of the Orange Scale. 



Aphelinus aspidioticola, n. sp. — Head and thorax light reddish brown ; 

 head nearly same width as thorax, three ocelli, eyes prominent, dark ; 

 antennae three-jointed (?), the last joint is club-shaped ; a dark brown spot 

 on thorax at base of each wing ; wings hyaline, both fore and hind wings 

 ciliated from end of costal vein ; no other apparent veins ; a small dark 

 reddish spot on fore wings at termination of costal vein ; abdomen rather 

 elongated, and of a darker shade of brown than the thorax, with two 

 oblong spots of very dark brown on each side ; legs rufo-testaceous, with 

 a tibial hair at junction with tarsi. There is also a short ovipositor, hardly
