Mr. Heidemann exhibited specimens of both adult and pupal 

 forms of H eidemannia cixiiformis, and adults of the new 

 species described in his paper. 



Mr. Schwarz mentioned the jumping habit of Heidemannia. 

 He said that adults could jump over 2 feet — farther than any 

 of the other Hemiptera-Heteroptera except the Saldidse. 



— Mr. Webb exhibited specimens of the hemipteron Pachy- 

 lis gigas Burm. which he found feeding on pods of mesquite 

 in the foothills of the Santa Catalina Mountains, southern 

 Arizona. These insects are interesting because of the greatly 

 enlarged femora of the males. They do not seem to cause 

 any serious damage to the plant.
