President Marlatt in the chair and Messrs. Ash mead, Patten, 

 Gill, Schwarz, Motter, Pratt, Johnson, Benton, Kenyon, Busck, 

 Banks, and Howard also present. 



Under the head of "Exhibition of specimens and short 

 notes," Mr. Johnson showed Tribolium madens, a species 

 w r hich had been sent to him from Montana in mill products. 

 This is the first record of such a habit in this northern species, 

 and he also said that he had found the previously unknown larva 

 of this species. He further showed a parasite of Gelechia cereal- 

 lela caught in the act of oviposition. Mr. Ashmead determined 

 this as probably a species of Dibrachys or Catoloccus. 



Mr. Schwarz showed specimens of Trigonoscuta pilosa, a 

 maritime species collected by Mr. Hubbard at Palm Springs, 

 Cal., and stated that Mr. Ulke possesses specimens of Cercyon 

 jimbriatum which may also come from this locality. This 

 latter species is also maritime, and Mr. Hubbard's finding tends 

 to substantiate the theory that the Colorado desert was formerly 

 an arm of the sea. 



Mr. Schwarz also showed a fragment of a specimen of a 

 Dynastid genus new to North America and apparently allied to 

 Golopha. This was found in the great mesquite forest south of 

 Tucson, by Mr. H. Brown. He discussed the entomological evi

 of the lower Colorado Valley, and showed that, while many new
