 galleries in dead stick of Cottonwood, Feb. 20, 1893.

Two of the above species, Cremastogaster lineolata and Tapi-

 lection made there by the California Academy of Sciences, and 

 sent to Mr. Theo. Pergande for determination. Mr. Pergande's 

 paper appears in the Proceedings, series 2, vol. iv, pp. 26-36.
