adopted and put in force a regulation prohibiting the importation of 

 cotton seed from points in Texas or Louisiana unless such cotton seed 

 is accompanied by a certificate, signed by a duly authorized State or 

 Government entomologist, stating that it has been fumigated in such 

 manner as to kill all adults, pupae, or larvae of the boll weevil that may 

 be contained therein. 



October 23 the writer found a number of pines dead and dying upon 

 a ridge near Cornelia, Ga. , which showed the work of a scolytid. The 

 work was identified by Prof. A. D. Hopkins as that of Dendroctonus 

 frontalis. So far as we are informed, this is the most southern point 

 from which this destructive species has been reported. The outbreak 

 at Cornelia is at present being investigated by Mr. W. F. Fiske, of the 

 United States Division of Entomology. 



Various insects of minor importance have appeared in greater or 

 less numbers during the year. 



INSECT NOTES FROM CONNECTICUT. 



By W. E. Britton, New Haven, Conn. 



Plant-lice have been extremely abundant the past season, and espe- 

 cially the green apple plant-louse (probably Aph is pomi DeG.), which 

 caused much damage to nursery stock and young orchard trees. This 

 pest attacks the leaves and stems of the new shoots, causing the leaves 

 to curl and noticeably checking the growth. Most of the nursery 

 stock this season is below the usual size on account of the injuries 

 caused by this aphis. In one large nursery the tops of the trees were 

 dipped in kerosene emulsion to kill the lice, but most nurserymen think 

 that they can not afford to apply any form of treatment to growing- 

 nursery stock. The green pea louse (Nectarophora pisi Kalt.) was 

 less abundant than during the preceding season, though many late 

 peas were injured. 



Pear trees were greatly injured by the pear psylla (Psylla pyrieola 

 Forst.), which was unusually abundant, and many trees dropped their 

 leaves completely during July and August. As this is a difficult insect 

 to combat, very little is usually done by the fruit growers. We found, 

 however, that a large proportion of the nymphs and some of the adults 

 could be killed by a careful spraying, even in July, with soap and 

 water (1 pound in 4 gallons). 



Lady beetles of nearly all kinds were abundant during the season. 



The San Jose scale insect has increased with great rapidity, and 

 many trees that were very slightly infested in early summer are now 

 completely incrusted. At the date of this writing (December 1) the 

 young are still crawling, though we have had freezing weather for a 

 week or more. The lime, sulphur, and salt mixture was used last win- 

 ter on more than 40,000 trees in Connecticut, mostly in orchards, with
