adults emerge and that then the emergence ie distributed over several seasons. 
Notes here record several such instances. 
Here for the first time for this area the galls of each host oak are listed. 
Lists on some kinds of oak are very incomplete as the oak was seen only a few 
times and only one time of year. For example little collecting has been done on 
the various oaks in Florida or on the Gulf Coast in the spring. Here ia an 
opportunity for the amateur to add to the lists. 
Probably this will be most frequently U3ed by someone wishing to learn the 
name of a curious growth on an oak or a rose. In that case if the host is known 
the place to look is in the host index and compare the short diagnosis there with 
the figure. Not all the described kinds are figured however. If the kind of oak 
is not known and, for instance, it is a detachable gall on the stem, one will 
find a list of all BUch in the check list which is combined with the notes on the 
illustrations. Similarly all the "root", flower, acorn and leaf galls are there 
listed regardless of host. Many kinds are still undescribed so one may fail 
to find it even here. 
The amateur should be warned that a single gall casually collected is seldom 
worth the trouble of trying to rear. It may be the normal reaction of the host 
to the stimulus of a cynipid ° r ib W ba ? uit9 abnormal lf ib has been modified 
ip size and structure by the attack of guests or parasites in its early stages. 
Only if found in numbers and on several trees is it probably the characteristic 
work of a cynipid and worth collecting and rearing. If one has trouble in 
naming gall-s send a number of each kind in a packet labeled with locality, date 
and host (if known or with a few leaves if not) to the writer at 661J N.Washing¬ 
ton Blvd., Arlington 1J, Va. Packets are b#st made of a tough paper such as a 
grocery bag. Number the packets and keep a duplicate under the same number. 
Sometimes a gall maker or guest is captured along with other insects in a net 
It can be run in the key to genus perhaps. No keys to the species in any genus 
are included and in the case of the large genua Disholcaspis it is not possible 
to separate the adults altho the galls are characteristic. Members of the
