small pits in the surface of the leaves, 
and most of all whether young plants 
are ever killed by small maggots eat- 
ing at their roots, or whether, on the 
other hand, maggots are found mining 
the leaves of Cruciferous plants, as is 
the habit of some flea-beetles in the 
larval stage. 
With regard to remedies for this 
beetle, it will be time to enlarge upon 
this subject when we hear more pre- 
cise information of its ravages, but 
we may mention that dusting with 
ashes, or the application ofPyrethrum 
powder would probably meet with 
Some measure of success, as it has in 
the case ©f other flea beetles. 
Two other injurious beetles of the 
same family (Chrysomelidse) are found 
in Colorado; one of them is the well- 
known Colorada potato -beetle (Lep- 
tinotaisa decemlineata,) which has 
not been met with in Custer county, 
and is apparently quite rare in Colo- 
rado, doing no damage compared to 
that caused by it in some of the more 
eastern states. The Colorado potato- 
beetle cannot be confounded with the 
flea-beetle, being very much larger, 
and dull yellowish with ten black 
stripes. The other injurious beetle 
of this family is known as Graptodera 
foliacea, and is found in Wet Mount- 
ain valley. This last resembles the 
flea-beetle of the cabbage, but is larger, 
and could not be mistaken for it by 
anyone familiar with both. It has 
done much damage to apple trees near 
Denver, and we shall therefore de^ 
scribe it in full in some future report. 
We hear from Dr. Geo. H. Horn 
that he is now studying these beetles 
monographieally, so we shall be glad 
of specimens of any of the flea-beetles 
(Halticidae) to send to him. He has 
already been good enough to examine 
and report on some beetles of this 
family for us. 
NOTES. 
In the first report we suggested the 
preliminary destription of new spe- 
cies from time to time, and described 
a new beetle. Since then, three 
much esteemed correspondents have 
written protesting against this course, 
and having weighed their arguments 
to the best of our ability, we conclude 
to revoke this p>rt of our original 
plan, and not to describe new specjes 
in these reports in future. We shall 
be glad to have the opinion of mem- 
bers upon this matter. 
Arrangements have been made for 
the publication of Entomological re- 
ports of the Association in “Psyche.” 
The exact form and frequency of these 
reports is not yet decided upon, but 
they will probably be monthly, and 
deal mostly with matters rather out- 
side the scope of the present weekly 
reports. 
Mr. Charles F. Morrison, who has 
charge of the Ornithological depart- 
ment of the Association, is now pub-
