reaction, but feigned death, stretching out the legs stiff 

 and exuding from the joints of the legs a yellowish liquid. 

 They often spent the night in the heart of the flower. 



Obthoptera 



Ischnoptera deropeltiformis Bninn. [A. N. Caudell]. 

 On May 10, these were taken during the day from 

 under the bark of a fallen tree. On June 26, at 4 a. m., 

 one was found on a leaf of a roadside plant four feet 

 above the ground. 



Ischnoptera pennsylvanica De G. [A. N. Caudell]. Ob- 

 served frequently at Wickes in June 1917. 



Ischnoptera uhleriana Sauss. [A. N. Caudell]. More 

 than a dozen of these brown roaches, all males, were seen 

 on top of leaves of oak bushes by the roadside at 8 p. m. 

 on June 10. 



Periplaneta americana Linn. [A. N. Caudell]. This 

 southern roach is now thoroughly established in a north 

 St. Louis planing-mill, having probably been introduced 

 with lumber shipped from Florida. 



Parcohlatta pennsylvanica De G. [A. N. Caudell]. Dur- 

 ing the first part of June 1919, at Manchester, Mo., the 

 males of this species were abundant at early twilight, 

 flying about the outside of an old log house, evidently in 

 search of females. Ten or twenty of these could be seen 

 almost any evening, but only once during the season did 

 I note a female. She was occupied with the most amorous 

 attention to the nearest male. She dashed about him 

 with commotion sufficient to attract the attention of the 

 most naive. Again and again he would turn indifferently 

 aside as she thrust herself squarely in front of him with 

 her demonstrations, but each time, undaunted, she 

 wheeled about and planted herself directly before him 

 with her ''tail" toward him, lifted the posterior part of 

 the body and her wings high in the air by stretching and 

 spreading the legs, and nervously vibrated the wings, as 

 though inviting him to approach. Since he did not re-
