SUBFAMILY IX. — PHYLIN^E. 933 



Raleigh, N. Car., Sept. 2 (Brimley). Ranges from Quebec and 

 New England west to Manitoba, Colorado and Kansas, and 

 southwest to North Carolina. Recorded also from California. 

 Host plants, ragweed, goldenrod, etc. The Lygus fuscosus Prov. 



(1872, 105) is stated by 

 Van Duzee (1912, 323) 

 - to be "very close to if not 

 identical with P. politus 

 Uhl." If the two prove 

 to be the same, Provan- 

 cher's name will have 

 priority. The color of P. 

 politus varies rather wide- 

 ly from that above given, 

 a paler form having been 

 described by Knight as : 



1042a ( — ). Plagiognathus 



POLITUS FLAVEOLUS 



Knight, 1923, 434. 

 In extremes of this form 

 the vertex, front margin and 

 middle spot of pronotum, 

 scutellum except basal angles, 

 base and apex of embolium, 

 basal third or more of corium, 

 basal half of cuneus, tibiae 

 and middle of femora are dull 

 greenish - yellow; remainder 

 of body brownish-fuscous. Size and structural characters as in politus.

More common in southern Indiana in late summer and 

 autumn than typical politus; Starke County only in the north, 

 Aug. 20— Oct. 10. Sherborn, Mass., Sept. 20 (Frost). Occurs 

 on flowers of goldenrod, thistle and other Compositae. All 

 variations in color between the extremes of this and politus 

 are found. The range of var. flaveolus as given by Knight ex- 

 tends from Ontario and New England to Minnesota. He states 

 that it "appears late in the season, no doubt belonging to the 

 second brood of politus, and breeding on Solidago and related 

 herbaceous plants." 



Examples of politus var. pallidicornis Knight, distinguished as 

 in j of key, p. 939, and having the same range as flaveolus are 

 at hand from Porter Co., Ind., and Pottersville, N. Y.
