The forty-seventh meeting was held on the evening of March 

 i, 1913, at the residence of Dr. F. E. Blaisdell, 1520 Lake 

 Street, San Francisco, Cal. 



President Van Dyke in the chair. Ten members answered 

 to roll call and nine guests were in attendance. 



A communication from J. N. Bowman in regard to the So- 

 ciety meeting with the Pacific Association of Scientific Soci- 

 eties was discussed. 



The death of Mr. L. E. Ricksecker was announced. Mr. 

 Cottle moved that the secretary be instructed to express the 

 regrets of the Society to Mrs. Ricksecker and family. The 

 motion was seconded and unanimously approved. 



Prof. Wm. A. Hilton, editor of the Pomona Journal, Clare- 

 mont, California, and Miss Ximena McGlashan, of Truckee, 

 California, were elected members of the Society. 



The secretary read a paper by Mr. R. F. Sternitzky, the 

 author being absent. It was a "Report on Two Collecting 

 Trips to Lake Tahoe." During the latter part of August Mr. 

 Sternitzky collected seven large larvae of a Syrphid, probably 

 of the genus Microdon, from ants' nests. He mistook the 

 Microdon larvae for a species of Coccid a Lecanid. Its mark- 

 ings are radial lines, similar to those of some Coccidae. He 

 stated that he was sure of one thing that these larvae do not 

 derive nourishment from the ants, as they throve quite well 

 on moist wood. It was thought that the ants might have some 

 use for them. The following is a list of the rarer Coleoptera 

 taken during the trips: Buprestis conne.ra, Acmacodera van- 

 d\kei, Ulochaetcs leouinus, Tragosoma pilosicornis, Ptero- 

 stichus morion-ides, Tachys fallii, Argonus dnerarius, Lcptura 

 valida, Pachyta spurca, Adelocera rornlcnta, Melasis rufipen- 

 nis and Serropalpus barbatiis. Dr. Van Dyke believed that 

 the Syrphid larvae were dependent on the ants. 



Mr. Bridwell stated that he took Dichelonycha dypeata in 

 Wild Cat Canyon back of Grizzly Peak, Alameda County, Cal- 

 ifornia, on February 13, 1913. Eight specimens were secured. 

 The beetles were flying high up among the laurel trees.
