tracting the milky substance. As mauy as ten individuals were ob- 

 serv-ed thus eini)loyed on a single ear at the same time. 



Nysius angustatus, — On November 2, 1885, we observed the sexes of 

 this species in great numbers in coitu under Uuphorbia macuiata, and a 

 week later obtained eggs from females taken at the time, and also 

 found them under the Euphorhia. Prof. Herbert Osborn secured 

 adults (pairing) and pupse on November 15, 1887.* As neither Pro- 

 fessor Osborn nor myself have observed adults in the spring, and my 

 eggs did not hatch during the autumn of 1885, it would appear prob- 

 able that the species winters over in the o^gg. I was absent from home 

 during the spring of 1886, and lost track of the matter. 



Orchelinmm vulgare. — An adult male was observed September 4, 

 1888, engaged in feeding upon the substance of kernels of corn at tip 

 of ears in field near La Fayette, Ind. In November, 1886, stalks of 

 corn were received from Mexico, Mo., with that part below the tassel 

 and above the upper joint fairly riddled with the egg punctures of 

 0. glaberrimum. So numerous were these eggs that the farmers errone- 

 ously supposed them to cause sickness among horses fed upon the 

 stalks.

The Green-striped Maple-'worm. 



I received the Bulletin from yonr Department for March, 1890 (Vol. II, No. 9, In- 

 sect Life), containing my letter and your reply abovit the Dryocampa rubieunda 

 (Maple Worms). Having some additional experience to give that I hope is worth 

 something, I write again. Last year the worms appearing again as abundantly as 

 before, we determined to see what could be done. So when the second crop of 

 moths came we followed your advice and destroyed as many as possible, trampling 

 them down as they came out of the ground towards evening. Then when they had 

 hatched out and were still small, by the advice of Prof. W. A. Kellerman, of Kansas 

 tstatc Agricultural College, and Professor Tracy, formerly of this State University, 

 n<iw of Mississippi, we sprayed the trees with Paris green, 2 ounces of poison to 5 

 gallons of' water. Some of the trees were sprayed but once, others twice, but the 

 result was the same— no worms, and our trees were green while all around us the 

 trees were stripped bare as before. This spring (the fifth season) in mauy yards it 

 seemed as if every blade of grass was covered with the moths. By dint of watching 

 we found fifteen only in our own yard, while by stirring up the people through the 

 papers we have persuaded many to try the spraying, and those who have done so 

 are happy in freedom from the pest, with green trees, while others are, as heretofore, 

 bare of leaves and trees, walks, fences, and houses covered with the disgusting things. 

 I am persuaded that in this way the trees may be saved.— [Mary F. McCluney, 214

London Purple for the Rose Chafer. 



I have the honor to report that about the 15th of May last, the Rose Bug appeared" 

 and swarmed in my vineyard in countless thousands. They proved very destructive, 

 feeding not only upon the foliage but also attackiug the fruit clusters just then
