me kinds of trees from which they were collected, or a variety 
if foliages, placing the small branches of foliage in bottles 
f water in order to keep them fresh. The foliage should be 
hanged as required (every three, four, or five days) during the 
life of the beetles. As the beetles die, those remaining on the 
surface should be removed and preserved for future reference. 
Two or three grubs should be preserved the fall of the first 
and second years, respectively. They may best be preserved by 
placing in test tubes of water and heating to nearly the boiling 
point. The grubs are allowed to remain in the heated water about 
ten minutes or until the liquid is quite cooled, after which 
they are preserved in 70 or 80 per cent alcohol. 
" #£«When the grubs are nearly mature (first of July of third 
year in Northern States and probably the second year in the 
Southern States) part of the cages should be examined and grubs 
removed to 1 ounce shallow tin salve boxes with earth and & 
grain of corn. ‘These should be examined often to determine the 
date of pupation and later the date of emergence of the mature 
beetles. Pupse of each species should be preserved. 
tn order to determine what species are known to injure 
‘crops and which species are of the most economic importance in 
the various localities, it is desirable that collections of lar- 
‘vVae be made following the plow and data on the rotation the 
past three years noted. From this source it is also possible 
‘*o secure data on the preference of the female for certain soils 
‘and crops for oviposition. If the observer has an opportunity 
to collect grubs but has not the opportunity to care for them 
they may be sent to us in shallow tin boxes, one grub to a box. 
Grubs collectei from the furrow should be placed in shallow 1 
ounce tin boxes (only one grub to a box) with earth and a grain 
‘of corn. Water and replace the corn 48 needed, and with a little 
care the adult beetle can be reared. 
Tf the collector has an opportunity to send specimens to 
us early in the season they will be promptly returned, properly 
identified and with notes on the distinguishing characters. Or, 
if any one contemplates rearing Lachnosterna we will furnish all 
available data concerning the species known to inhabit his ; 
locality. For many States our data are very meager, which makes 
it most desirable that extensive Collections be made wherever 
possible. This is especially true of the Scuthern States. Our 
mowledge of the food habits of many species 18 also meager and 
information along this line, either from night collections or 
from rearing-cage feeding records, is very desirable. Where 
possible, material should be preserved in 70 or 80 per cent alco- 
“hol, never in formaldehyde. If the collector prefers to pin the 
specimens, then the gexual organs should be extruded. Parasites 
may be reared by confining in 12-inch pots large numbers of bee- 
tles collected from trees when most abundant or a little later, 
to be fed as those in rearing cages. Parasitized beetles should 
be removed to other sunken pots and kept until the following spring.
