The histories of 5 adults reared in the summer of 1915 are summa- 

 rized below. The larvse were all collected from codling moth bands 

 on trunks of apple trees. 



No. 1. This larva was the one mentioned as placed in the cage with the original larva 

 on September 7, 1914. Pupation had taken place by May 30, 1915. An adult 

 male clerid beetle emerged on June 14, 1915. In the approximate 9 months 

 17 codling moth larva; were eaten. 



No. 2. The larva of this specimen was taken with 8 others on December 30, 1913. 

 All were about two-thirds grown. One adult female emerged June 14, 1915. 

 One larva was alive, 7 had died in the 17^ months since the 9 were taken. In 

 that time 29 codling moth larva; had been fed to these larvaj. 



No. 3. The nearly grown larva of this specimen was confined alone on March 15, 

 1915. It had pupated by May 29, 1915, and an adult female emerged June 14, 

 1915. In 3 months it ate 4 codUng moth larvae. 



Nos. 4 and 5. Two large larvse were taken Jan. 19, 1914. Four others of about the 

 same size were placed with these June 23, 1914. Two emerging adults were 

 taken June 14, 1915 and placed in alcohol before completely out. The sex 

 was not recorded. The 4 other larvse were dead and all but 1 partly devoured. 

 In the 17 months 34 codling moths were eaten by the six. It can not be 

 decided if the two adults were the two placed first in the cage. 



The adult male and two adult females were placed in a cage together 

 on June 14, 1915. On June 15 the male and one female were found 

 in coitu. The female had chewed a hole in the thorax of the male 

 injuring him so that he died the same day. This day the female ate 

 1 larva and 1 pupa of Autographa sp. Two days later she ate the 

 same amount. On June 26 she was fed 2 larvse of the Autographa and 

 several codling moth larvse. She did not eat well and died August 23, 

 1915, after being in a very sluggish condition for about six weeks. No 

 eggs were found. 



To Prof. H. F. Wickham, Iowa City, Iowa, the writer is kindly 

 indebted for the specific determination of the adults and for numerous 

 helpful notes and citations concerning certain clerids. The species 

 was given by Professor Wickham as Cymatodera cethiops Wolcott, the 

 citation to the description being given as "Field Museum of Natural 

 History PubUcation 144, Zool. Series, vol. VII, No. 10, p. 350, May 

 1910." "The type was from El Paso, Texas. The cotype from 

 Tucson, Arizona, both collected by me," Professor Wickham states. 

 Further he says, "Cymatodera is usually beaten from partly dead 

 branches and shrubs, or found hiding under loose bark." 



The writer has taken adults at lights at State College, N. M. The 

 specimens hatched out in the laboratory here, however, solved the 

 question as to what species to refer the larvse preying upon the codling 

 moth larvse. The term "warriors" applied to these predators by Mr. 

 Stuart, an orchardist near Mesilla Park, N. M., is a very fitting com- 

 mon name.
