Notes on Two Beetles Reared from Dead Wistaria 



Sticks (CoL). 

 By Dayton Stoner_, State University of Iowa, Iowa City, la. 



While trimming off the dead branches of a Wistaria vine 

 (Wistaria chinensis DC.) at my home on May 28, 191 4, I ob- 

 served that some of these dead tw^igs showed evidences of 

 the work of wood-borers. A few of the twigs were cut off 

 and placed in a loose-topped glass jar in the Entomological 

 Laboratory of the State University of Iowa and on the follow- 

 ing day, May 29, two adult Chrysobothris azure a Lee, male 

 and female, emerged. This species has not before been re- 

 corded from Iowa. 



(Dn May 29, while again trimming the same vine, I found 

 a specimen of Lepturges querci Fitch crawling on one of the 

 branches. This time a number of short pieces of the dead 

 vine, amounting in all to about 18 feet, were removed to a 

 glass jar in the laboratory and devolopments awaited. The 

 diameter of the sticks varied from ^ inch to about i inch, 

 those nearer the base of the vine and hence of the larger di- 

 ameter being most heavily infested. The smaller branches of 

 the vine above 5 feet from the ground were apparently not 

 infested although many were dead, due, very probably, to 

 the work of the larvae in the larger stems lower down. The 

 glass jar containing the sticks was kept on a shelf where sun- 

 light could not strike it and where it was not directly exposed 

 to daylight. A temperature of between 70° and 80° Fahr. was 

 maintained in the room. 



The two species of beetles emerging from the wood, to- 

 gether with the dates of emergence and number of each spe- 

 cies, are indicated in the following table : 



Chrysobothris asurea Lee. Lepturges querci Fitch.
