eR On ie, 4th of “May of the present season I marked a large number 
of females which were located upon the trunk of an orange tree that was 
not in a very healthy condition. These females had just begun to secrete 
the cottony matter, the latter at this date being in the form of short but 
broad tufts around the margin of the abdomen, those at the-hind end of

Tod upon sickly trees, owing doubtless to the fact that the females
