Mr. Popenoe has experimented with beans as well as with peas, with 
the following result: 
Fifty per centstarted; ofthese, three-fifths might have grown into plants, as the in- 
jury was restricted to the seed leaves. But the remaining two-fifths were variously 
mutilated by the loss of a part or the whole of the germ or plumule, so that under 
no circumstances could they have made plants. Here, then, but 30 per cent could 
have passed the germinating stage, and these, owing to more or less considerable 
injury to the seed leaves, would probably have made plants of low vigor. In a 
_ check lot of perfect beans of the same varieties and in the same numbers, planted 
alongside, 95 per cent germinated. 
The remedies for this insect are the same as for the Pea Weevil, 
except that keeping the imported seed over two years in tight vessels 
will be of no avail for the Bean Weevil. Careful experiments with 
bisulphide of carbon show that in this substance we have an almost 
perfect remedy for both species.*

HABITS AND NATURAL HISTORY OF HYPODERMA LINEATA. 
By: C 2y— Rite 
A good deal has been written recently about this insect, both in this 
country and Europe, and, as has been intimated in previous numbers 
ot INsEcT LIFE, some interesting discoveries have been made, which 
haye materially modified the old conceptions of the life-history and 
habits of the species. Of first importance is the fact which has been 
recently developed, namely, that the older Ox Bot-ily, Hypoderma bovis, 
hitherto supposed to be the common species of both America and Europe, 
is in reality either a very rare insect in this country or possibly does not 
occur here at all. 
THE AMERICAN SPECIES IS HYPODERMA LINEATA, 
The Ox Warble of this country is referable to a distinct species, 
Hypoderma lineata Villers. It was first described in 1789 as @strus 
lineatus (Ent. Linn. m1, p. 249). It was subsequently described by Dr. 
= Since this article was prepared, and just as it was being sent to the printer, we 
received Dr. J. A. Lintmer’s Seventh Report on the Injurious and other Insects of the 
State of New York, and find an elaborate article upon the Bean Weevil, covering 
pages 255 to 279. Dr. Lintner gives an admirable summary of the previous knowl- 
edge concerning this insect, overlooking, however, our note of 1882, to which we 
have referred, and adding observations of his own proving successive broods in stored 
beans and showing the duration of asingle generation to be about two months. The 
article also discusses at length the question of synonymy, into which we have pur- 
posely not entered in this paper, and although he uses the name Bruchus obsoletus 
Say at the head of the article, he finally concludes that Bruchus fabe of Fitch should 
in reality hold unless an earlier European synonymy should be established, as seems 
probable. This question, however, we will discuss in our next issue.
