Male July 14, at Lakeland, Md. (W. L. McAtee). 



I have only one record each for worker and male. 



9. Bremus fraternus (F .Smith). 



One worker from Colonial Beach, Va., is the only specimen of 

 this species I have seen from near here. Mr. J. C. Crawford, for- 

 merly of U. S. National Museum, has taken one specimen of this 

 species near Bethesda, Md. If it breeds here regularly it is 

 extremely local in distribution. 



10. Bremus separatus (Cresson). 



About as common as auricomus. 

 Queens May 7, at Plummer Id., Md. 



.Sept. 16, near Glen Echo, Md. 

 Worker June 8, at Cherry Hill, Va. (J. Silver). 



July 25, at Rosslyn, Va. (W. L. McAtee). 

 Male July 25, at Great Falls, Va. (W. L. McAtee). 



Aug. 1, at Mt. Vernon, Va. 



Psithyrus laboriosus (Fabricius). 



Only one species of this genus occurs here. The female may 

 be told by always having first two dorsal abdominal segments 

 black, usually the entire abdomen is covered with black pile. 

 The male has a rougher, more unkempt appearance than any male 

 of Bremus found here, though perplexus males approach it. 



Females occur from May 17 to August 29, and the one male 

 I have from this locality was taken July 28. 



SOME NOTES ON THE GENUS TRACHYKELE WITH A DESCRIPTION 

 OF A NEW SPECIES (BUPRESTIDAE, COLEOPTERA). 



BY H. E. BURKE, Bureau of Entomology. 



Seventeen years ago Mr. E. A. Schwarz showed the writer the 

 single specimen of Trachykele then in the United States National 

 Museum and said: "Do not bring in the common things. Get 

 the rare ones. Get the rare ones." Since that time over a hun- 

 dred specimens of the four named species have passed through 

 the hands of the writer and the Museum now has the most repre- 

 sentative collection of Trachykele in the world. All from the 

 deep impression made on the mind of a young collector by the 

 inspiring words of Mr Schwarz. 



In April, 1919, Mr. R. D. Hartman, of the Los Gatos Forest 

 Insect Laboratory, collected at Mt. St. Helena, Lake County, 

 Calif., in the Sargent cypress (Cupressus sargentii) an adult of 

 an apparently very distinct species. Larvae and infested wood 

 were collected at the same time and on May 26 and May 29, 

 respectively, two more adults of the same form emerged.
