From the puparium of this fly I have bred the following parasite : 
The Syrphus Fly Pachyneuron — Pachyneuron allograptae n. sp. — Female. — 
Length .08 inch. Black, rather coarsly punctate, with a slight metallic luster. Head 
large, face and cheeks full ; eyes brown ; antennae brown, scape rufous ; legs tawny 
yellow, a large brown blotch on fore -and middle femora, while the hind femora are 
almost entirely brown ; abdomen flattened, oval, shiny black ; wings hyaline, veins 
pale brown; the bristles on eubmarginal vein are not long and are difficult to count. 
Male. — L ength. 0l5 inch, otherwise similar to female. 
Described from f-everal specimens. The large size of this species and color of legs 
will distinguish it from others in our fauna. 
Besides the above parasites there is a small Coccinellid that preys on 
the Cabbage Aphis, viz, Scymnus cervicalis. 
OTHER INSECTS FOUND ON CABBAGE IN FLORIDA. 
A Centipede (Julus muJtistriatus) Say, a Cricket ( Tridactylus minutus 
Scudder), the Southern Cabbage Butterfly (Pieris protodice Boisd.), the 
Large Cabbage Butterfly ( Pieris monuste L.), the Cabbage Mamestra 
(Mamestra clienopodii Albin.), the Zebra Cabbage Worm (Ceramica picta 
Harris), the Cabbage Pionea ( Pionea rimosalis Guen.), the Cauliflower 
Botis ( Botis repetitalis Grote), the Harlequin Cabbage Bug (Murgantia 
Mstrionica Hahn.), and others. 
INSECTS AFFECTING CORN. 
The lateness of the season at which I began my investigations pre- 
cluded me from studying insects depredating this crop in its earlier 
growth; consequently nothing can be reported of the cut- worms and 
borers that do so much injury to this crop in early spring. 
THE CORN WORM. 
( HeliotJiis armigera Hiibn.) 
This well-known insect has been very plentiful and injurious in 
Florida during the past season. Not a field of corn was free from its 
attacks, and but few perfect ears could be found that were not bored 
into by this pest. 
From ears taken from a field near Jacksonville I obtained from eight 
to a dozen worms in each ear, and out of the whole patch hardly an ear 
could be found that had less than two or three worms in it. 
The insect is treated in full in the Fourth Report of the IJ. S. Ento- 
mological Commission, and a repetition of its life-history, habits, and 
remedies are unnecessary here. 
Its Injuries. — Enormous injuries are committed by this worm, whole 
fields of corn being almost entirely destroyed by it. The eggs are laid 
on the leaves, and the young larvae, which hatch therefrom, begin by 
eating the leaves, but they soon leave these and bore into the tender 
ears, gnawing and eating them in all directions, so that frequently 
hardly a perfect ear can be found. At times it is also found at the
