European Com Borer in Broom Com. Early in February, 1920, a shipment of 
broom corn infested by the European corn borer was received at New York from 
Venice, Italy. This consignment was intercepted by Mr. H. B. Shaw, inspector for 
the Federal Horticultural Board. The broom corn originated in the territory of 
Venetia, Northern Italy, and consisted of 97 bales, each weighing about 200 pounds. 
Upon examination it was found to be infested to a considerable degree, the per¬ 
centage being somewhere between 1 per cent and 5 per cent of the stalks. Large, 
nearly full grown larvae as well as pupae in a live and healthy condition were found. 
These larvae were determined by Mr. Heinrich, of the U. S. National Museum, as 
Pyrausta nubilalis Hubn. 
The broom corn stalks were about 36 inches long, of which at least 15 inches con¬ 
sisted of the butt. The larvae were found throughout the length of this butt and in 
most instances had extended their tunnels into the extreme upper tip of the terminal 
internode, beyond the point where the hurls are given off. 
This incident obviously strengthens the belief already held that broom corn was 
the host in which the European corn borer gained access to this country, and appar¬ 
ently established the evidence submitted by Mr. Harrison E. Smith, in his paper 
appearing in the next number of this Journal entitled, “Broom Corn, the Probable 
Host in Which Pyrausta nubilalis Hubn. Reached America.”

Aphids and Coccids. Species of both are of considerable economic importance. 
As many of the American species are identical with or closely allied to European, it is 
doubtless desirable to have material of European species for comparison ready at 
hand. From the correspondence that I have had with a number of American col¬ 
leagues since the conclusion of the war, I see that this desire actually exists. Doubtless 
the study of aphids and coccids will be considerably advanced in the presence of such 
comparison material. As I have during recent years extended my studies also to 
these insect groups, it will be no difficult matter for me to satisfy these desires. I 
wish to announce that I will gladly undertake to furnish such material to interested 
American colleagues and by means of this circular I am addressing a call to the Experi¬ 
ment Stations and specialists for the attention of those that wish to get in touch with 
me. The distribution of the material will be entirely gratis. By way of reciprocity, 
I should like to have the stations place my name on their regular mailing lists of their 
publications.
