Deraeocoris quercicola pallens new variety 



5 9. Structurally nearlj^ identical with the typical quercicola but differs in 

 color characteristics as follows : front of head pale or with the dark spots much 

 reduced ; calli frequently with pale on the disk of each, pronotal disk rather 

 uniformly colored; scutellum pale, rarely with some blackish each side of the 

 median line; hemelytra pale to yellowish, cerium with a spot at middle, small 

 one at base, and irregularly at apex, blackish.

Apparently only a color variety of quercicola but one which the 

 writer has found rather consistently on Quercus macrocarpa. The 

 color pattern is fixed shortly after the adult emerges and is retained 

 throughout the life of the insect. Tenerel forms of the typical species 

 pass through the color stage represented by pallens but when allowed 

 to live, the darker colors are developed and fixed within a few hours 

 after emergence. 



Deraeocoris davisi new' species 



Slightly smaller than nitenatus, uniformly brownish black, legs and anten- 

 nae chiefly pale ; genital claspers very distinctive, nearest to quercicola but the 

 internal arm of the left clasper more highly developed.
