An Active Ant-killer (Arach., Solpugid.). 

 April 25th of this year, Mr. Frank B. Richardson, of San Diego. 

 Texas, sent me a specimen of an interesting Solpugid, Ercmobates 

 magnus (Hancock), which was determined by Mr. Clarence R. Shoe- 

 maker, of the National Museum. Mr. Richardson found the specimen 

 destroying large sized ants. He took it to an ant hill, and in a few 

 minutes it killed "hundreds of ants." Mr. Richardson pointed out 

 that these ants are a great pest at San Diego and especially to freshly 

 planted seeds. He stated that they had carried away about 20 pounds 

 of grass seed which he recently sowed. He further stated that he 

 would very much like to "promote the multiplication" of this import- 

 ant ant enemy. — L. O. Howard, U. S. Bureau of Entomology, Wash-
