I? 



Notes. 



A complete summary of the last season's work of the San Pedro 

 Biological Station of the University of California is made by Dr. W. E. 

 Ritter in Science, Jan. lo, 1902. 



Prof. W. W. Campbell, Director of the Lick Observatory, will lecture 

 before the Academy at the March meeting. 



"Last July, at Downey, Los Angeles, County, California, I had an op- 

 portunity to examine an orange orchard. I was greatly interested to find 

 Mytitaspis beckii {^N\\\c\i.,\.\.\x^&^\.o be said, would not live in California) 

 excessively abundant and injurious on the leaves and fruit. On the same 

 trees the old California pests Saissetia olece, Aspidiotus aurantii and Icerya 

 purchasi were also present, but in such insignificant numbers that all three 

 combined would not do any appreciable damage. I had difficulty in get- 

 ting enough of the Icerya for certain identification. I do not know how 

 widespread this condition of aflfairs may be; Dr. Howard, to whom I men- 

 tioned it, told me it was new to him." — T. D. A, Cockerell, in Entom. 

 News, Jan., 1902. 



The Chayote, a tropical vegetable of the gourd family, said to be su- 

 perior to the summer squash and vegetable marrow of cultivation, is recom- 

 mended in Bulletin No. 28, U. S Dept. of Agricult., as a probable valuable 

 food plant for Californians. It has been grown at Santa Barbara for some 

 years and is a rapid growing vine with an abundance of fiowers that pro- 

 duce much honey. 



The Delphiniums of the west threaten to become as much of a puzzle 

 to our botanists as the blackberry bush was to the English. Miss Alice 

 Eastwood (Torrey Bulletin, Dec. 19c i) discusses D. decorum, and its allies, 

 and, by way of elucidation, adds three new species and two varieties, all 

 native of northern and middle California. 



The Academy of Sciences of Southern California aims to make its 

 Bulletin the best representative magazine of its kind in the west. To fully 

 attain this end we require and desire help from all workers in nature's field. 

 The entomologist, zooiogist, geologist and botanist will be accorded space 

 for any article of scientific value; if illustrations are forwarded these will be 

 reproduced without any expense to the writers. Lists of species and ad- 

 ditions to lists already published always prove useful to investigators. 



Quite a respectable number of new species have been added to the 

 flora of the west during the season just passed. We have made arrange- 

 ments to present one or two of these with illustrations in each succeeding 

 number of the Bulletin. 



Mr. Henry Skinner (Entomological News, Jan. '02) describes two new 

 butterflies from California. Lycaena neutona, from Doble, San Bernardino 

 county, and Lycaena chlorina from Tehachapi. 



In the Journal of Malacology, 1901, Vol. VIII, pt. 3, Mr. T. D. A. 

 Cockerell reports three new Nudibranchs from Califoi-nia. Coryphella 

 cooperi and Facelina stearnsi, from San Pedro; and Thecacera velox, from 

 La Jolla, San Diego county. 



Volutomitra Alaskana, a new deep water shell ranging from Alaska 

 to San Diego, is described by Mr. Dall in Nautilus, January, '02.
