base of the tassel, feeding on the accumulated saccarhine juice, found 
there, just before the tassel emerges from its sheath. 
The worms will not only gnaw irregular burrows and feed on corn 
while in the milk, but the mature larvae are known at times to continue 
feeding on mature hard corn. 
I have taken on corn two hemiptera or bugs which probably prey on 
the worm, although not detected in the act — the Wheel Bug ( Prionidus 
cristatus L.) and Euschistus servus Say. From the egg I bred Triclio- 
gramma pretiosa Biley, already noticed; but no other parasite has been 
bred from it by me. 
THE CORN MINING- FLY. 
(. Diastata sp?) 
A mining fly larva is quite frequently met with, making long irregular 
mines on corn leaves, and while I have not been able to rear the perfect 
fly, yet I am satisfied it is the same species mentioned by Prof. Com- 
stock, in U. S. Agricultural Beport for 1880, page 245, as Diastata sp. 
Several specimens of a parasite, agreeing tolerably well with Mr. 
Howard’s Entedon diastatce , reared from it at the North, were also bred 
from it here. 
MISCELLANEOUS CORN INSECTS. 
A Hemipteron ( Oebalus pugnax Fabr.) was found in considerable num- 
bers feeding on corn pollen, along with a Capsid and several flies. A 
fly ( Ortalis sp.) is common on the stalk, but was not observed to do any 
injury. A common beetle ( Allorhina nitida Linn.) was taken, with head 
immersed in the ear, feeding on corn while in the milk. 
OTHER INSECTS INJURING- CORN IN FLORIDA. 
The following insects also injure corn here: The Corn-stalk Borer 
(. Diatrasa saccharalis Fabr.); the Corn Bill-bug ( Sphenophorus robustus 
Horn.), and the Angoumois moth ( Gelechia cerealella) and several Cut 
Worms. From the tassels I have taken the larvae of Nola sorghiella 
Biley, and in the crib the Corn Weevil ( Galandra granaria). 
INSECTS AFFECTING THE TOMATO. 
The cultivation of the Tomato for Northern markets is a rapidly grow- 
ing industry in Florida, particularly in the southern portions of our 
State ; and thousands of boxes are now forwarded by our growers to 
Northern commission men every season. 
It behooves us, therefore, to keep a watchful eye on the insect depre- 
dators of this fruit, for we may naturally expect, with the extension of 
any horticultural industry, a corresponding increase of insect pests. 
Fortunately, no serious damage done this plant by insects has been 
reported this season, and, while I have been unable to visit West and
