This would certainly account for a small part of the difference in the 
percentages of damage in the two orchards. 
There seems to be no question as to the successful outcome of the 
experiment, and Mr. Hale, who shipped 145 ears of fruit from the 
orchard, considers the money required for the jarring well spent. 
A study of the collections of insects made by thus jarring the trees 
has revealed many interesting features as regards the species present 
and their comparative abundance. About 325 species were mounted 
and determined; the larger part were found in insignificant numbers, 
but many were abundant. Outside of the Coleoptera and Hemiptera, 
very few of any order were taken, and of these no record has been 
kept. The presence in considerable numbers of the peach borer, San- 
nina exitiosa, during the early half of May is, however, worthy of note. 
LIST OF FAMILIES REPRESENTED. 
COLEOPTERA. 
The Coleoptera easily outnumbered the Hemiptera, even without 
considering the immense numbers of curculio, and many of the species 
were of economic interest. The list of families represented is as 
follows: 
CARABID4:.—Very few specimens early in the season, but many at later dates. 
Lebia, as might be expected, was common; Calosoma sayi, wilcoxi, and scru- 
tator were scarce, but conspicuous from their size and color; Platynus was 
the most common genus, and represented by several species, of which lim- 
batus was present in the largest numbers. 
PHALACRID4.—Scarce. 
COCCINELLID&.—These beetles, of such great economic importance in reducing 
the numbers of such widely distributed scales as Aspidiotus forbesi, etc., were 
sorted from the jarrings as made and set at liberty. Thus no good idea could 
be obtained as to their actual abundance; but, judging from the large num- 
bers that escaped the mercy of the sorters, very large numbers must have been 
originally present. Thirteen species were identified (counting Scymnus as 
one), the most of them known as scale feeders. The most common was, how- 
ever, Anatis 15-punctata, with a close second in Hippodamia convergens. 
Among those that have been especially noted as feeding on the scales infesting 
peach in Georgia were Coccinella sanguinea, common; Chilcorus bivulnerus, 
common; Hxochomus tripustulatus, scarce; Hyperaspis signata, scarce. 
Scymnus was common, but the species are as yet undetermined. Strangely 
enough, Adalia bipunctata, which occurs about plant-lice in swarms, was 
wholly lacking. 
ENDOMYCHID.®.— Very rare. 
EROTYLID4.—Scarce. 
DERMESTID.4%, NITIDULID®, TROGOSITID 4%, and DASCYLLID4:.—All rare. 
ELATERID#.—Abundant. The species, however, largely such as breed in rotten 
wood, such as the old stumps often occurring in orchards, or in its environs. 
For instance, Alaus myops was common and conspicuous; Perothops mucida 
was very common in some lots, and in general the species were of little eco- 
nomic interest. 
THROSCID2.—Rare. 
BuPRESTID®.—Abundant. The collections in this family were interesting, prin- 
cipally on account of the abundance of the genus Chrysobothris, C. femorata
