varied from 12 to 24 days. Of 526 wormy apples, 424 were found to have worm 

 lioles at the blossom end, while 84 liad lioles at the side and 18 at the stem end. 

 The earliest date for the appearance of a moth of the second l)roo(l was July 13 and 

 the latest date Septend)or 1(3. The first eggs of the second brood were observed July 

 24 and they were most abundant on August 12. The time between the broods 

 according to these observations is about 54 days. The author concludes that the 

 codling moth is definitely two-brooded throughout Colorado and that there is no 

 reason for assuming the existence of a partial third brood. 



Jarrinyfor the cnrculio on an extensive scale in Georgia, with a list of the insects caurjlit, 

 W. M. Scott and W. M. Fiske (pp. 24-35). — The curculio is reported as causing great 

 annual damage to peaches and plums in Georgia, 25 per cent of the crop being 

 destroyed. The adult beetles are also instrumental in disseminating ))ro\vn rot fun- 

 gus. Jarring experiments were conducted in a large orchard containing 200,000 peach 

 trees and 50,000 plum trees. These trees were all jarred several times between April 

 18 and June 1, some of the trees being jarred 6 days per week. The jarring was done 

 from 3 a. m. until 9 a. m. and from 2 p. m. until dark. The best results were obtained 

 in the morning. The beetles were caught on rectangular frames covered w ith canvaa. 

 The total cost of the work for the season was $1,000. Of the 325 species of insects 

 which were thus caught, a list of which is given, over 67 per cent were curculios, 

 the total number of curculios being 137,000. The amount of curculio damage on the 

 jarred trees was 4 per cent, while in an adjacent orchard of 130,000 trees where no 

 jarring was done, the damage was 40 per cent. 



A simple form of accessions catalogue, E. D. Ball (pp. 37-39). — According to the 

 scheme proposed by the author an accession catalogue is recommended containing 

 one entry for each trip or special collection, this entry being in the form of a date 

 giving the year, month, and day. Every specimen as it is labelled bears the place 

 of capture and the date on a single small label. The advantage of the system lies 

 chiefly in the great saving of time. 



A preliminary report on the San Jose scale in Japan, C. L. Marlatt (pp. 41-47). — Evi- 

 dence is presented supporting the conclusion that the San Jose scale is not native to 

 Japan but was introduced from Ajnerica. A related species, Diaspis pentagona, is 

 native to Japan and is prayed upon by a beetle, Chilocorus simills, which also feeds 

 to some extent on the San Jose scale. The latter species is attacked by a fungus dis- 

 ease and by one or two parasitic insects. 



Further notes on crude petroleum and other insecticides, E. P. Felt (pp. 49-51). — Trees 

 were not injured by spraying with 20 or 25 per cent mixtures of oil. Experiments 

 with a 10 and 15 per cent mixture of crude petroleum in combination with a mixture 

 of whale-oil soap containing 1 lb. to 4 gals, showed that no injury was done to the 

 trees and the San Jose scale was thoroughly checked. Spraying with whale-oil 

 soap solutions gave good results, but it was not quite so effective as crude oil. 



Notes on some Colorado insects, C. P. Gillette (pp. 51-55).— Notes on the habits, life 

 history, and means of combating Nrjsius minutus, Aspidiotus howardi, CItermes alnetes, 

 grain plant louse, the apple aphis, beet army worm, cabbage Plutella, bean ladybird, 

 cabbage aphis, and a species of Phytoptus which attacks cottonwoods. 



A preliminary note on a new species of aphis injurious to plums and peaches in Georgia, 

 W. M. Scott (pp. 56-60).— A brief account is given of a species of aphis believed to be 

 new and reported as injurious to plums and peaches in different parts of Georgia. 

 Observations were made on a part of the life history of the insect. 



Fighting insects with fungus diseases, L. L'runer (p. 59).— The author reports that a 

 fungus was received from this Department supposed to be a South American Icjcust 

 disease, but which proved to be a species of Mucor. The material was distributed in 

 Nebraska, but was not found to be effective. In the author's experiments none of 

 the locust diseases proved successful.
