The small brown ladybird is Scymnus collaris Melsh., and the larger spotted one is 
Hippodamia convergens Guer. 
Nothing but the skins and webs of the spiders were received, and from these the 
species can not be determined. ag LP RnEUND ES 18, 1891. ] 
An injurious Blea beetle in Utah. 
FIRST LETTER.—I inclose some insects which are doing considerable damage to 
young tomato plants and young beans. They feed chiefly on the under side of the 
leaves, but feed on both sides during the middle ofthe day. At night they shelter them- 
selves under clods, especially where the plants are coming up. They crawl under the 
uplifted crust and not only shelter themselves but feed on the young plant before it 
gets above ground. Will you be so kind as to tell me what it is, and whether or not 
its life history is known? 
I first tried spraying with Paris green, but the plants were so small that I could 
not wet the under side of the leaves. Am now using arsenic mixed with flour and 
applying with bellows, but have not yet had time to note its effect.—[E. S. Richman, 
Utah, June 9, 1891. 
SECOND LETTER.—When I wrote you before I said I should try Paris green mixed 
with flour, but as I could not get the article in town I used white arsenic, and the 
application was followed almost immediately by a rain which killed over half the 
plants. I have since used kerosene emulsion with good results. Plants should be 
sprayed during the middle of the day while the insects are active. During the 
cooler portions of the day they have sheltered under clods and whatever rubbish 
may be available.—[E. 8. Richman, Utah, July 3, 1891. 
REpPLY.—The specimens came safely and proved to be a species known as Epitri« 
subcrinita Lec.. Your account of your experience is very interesting and the results 
are quite what I should have anticipated.—[July 11, 1891.] 
A new Enemy to Pear Leaves. 
In going through our pear trees, we noticed a little black-winged insect that was 
eating the soft leaves and doing considerable damage, considering their numbers. 
We inclose samples of both the insects and the leaves. Possibly you can tell us 
what they are and whether there is any way in which we can get rid of them, for 
evidently if they are undisturbed they will become quite a nuisance.—[Smiths and 
Powell, New York, August 11, 1891. 
REPLY.— * * * The insect which you send has no common name, but is known 
scientifically as Systena frontalis Fabr. It is comparatively new in the rdéle of an 
enemy to pear leaves, and the best remedy will be to spray with Paris green or Lon- 
don purple in the proportion of one-fourth pound of the poison to 50 gallons of 
water.—[August 26, 1891. ] 
Abundance of Colorado Potato Beetle in Georgia. 
* _* * The Colorado Potato Beetle was very numerous in this part this season. 
It is the first time I have seen them in any great numbers. I first observed them 
about twelve or thirteen years ago; just a few straggling specimens every year until 
thisone. I do not believe any one took the trouble to kill them, as but very few 
know them when they see them.—[George Noble, Georgia, July 31, 1891. 
A Grapevine Flea-beetle of New Mexico. 
Inclosed find box of bugs that appeared here on the evening of the 24th of this 
month. They came out of the ground from small holes, similar to those of ants, but 
came by the millions. They are devouring the grapevines. They strip a vine in 
about two hours. So far they have not attacked any other class of vegetation. What 
are they and what will rid us of them? I have killed millions of them by spraying
