ENTOMOLOGY.’ 
Some Observations on the Distribution of Coccide.’— 
Being now in the midst of preparing a new list of the known Coccide, 
with notes as to food-plants, distribution, etc., I have thought it oppor- 
tune to submit to you a few observations which seem to me to be of in- 
terest, relating to the geographical distribution of the several genera. 
In preparing these notes, I have, moreover, been moved by a lively 
hope that some of you who have so much unpublished information re- 
garding this group of insects, may be induced to throw a little fresh 
light on points which are now obscure. More especially do I refer to 
the numerous undescribed species which must doubtless exist in the 
colleetions at Washington, information of which would so greatly help 
to fill up blanks now too apparent to those who read our lists with a 
critical eye. 
The following genera, some of them not very well established, are 
monotypie aecording to present information. 
Walkeriana Sign. ; Ceylon.
