obsolete where a pale lateral stripe is formed, spiracles surrounded with pale 

 and this in turn by blackisli which occupies the basal half of each segment 

 above the pale lateral line, the genital segment dark tirownish black; genital 

 claspers (tig. 44) distinctive of the species. 



Lcctotypc: £ "Colo. 1690." |= July 10, 1894. on Grizzly Creek, 

 Jackson County, Colorado, from Artemisia tridcntata, alt. 9,500 ft.

The lectotype represents the second specimen mentioned under 

 the original description. The writer has specimens from Jemez 

 Springs, New Mexico, which are slightly darker in color than the type 

 but apparently not differing sufficiently even to be recognized as a 

 color variety.

In making a study of Walker's invaria])lv miserable descriptions 

 of Miridae, the writer was impressed by the color markings descril)ed 

 for Ca[>sus sfric/ittatiis. ]t just happens that in this case the color 

 markings will apply only to certain color forms of Lvi/iis l^ratcnsis, 

 and one very dark form in i)articular with which the writer became 

 familiar during a prolonged study of Lygus. Upon reading the de- 

 scription the writer turned immediately to this particular variety of 

 pratensis and checked over and conhrmed the few distitictive marks 

 given for striijulatiis. In this instance we must give Walker credit 

 for describing a form which could ncit very well be confused with any 

 species other than the varieties of Lyyits pratejisis. In fact this dark- 

 variety of pratensis may well be retained as a color variety and on a 

 par with oblineatiis Say. The writer has found variety strigulatus in 

 New York and Minnesota, occurring most fre([uently on weeds dtu'ing 

 August and September. 



Distant (1904), in making a study of Walker's types, places strigu- 

 latus in the genus Camptobrochis but this might l)e expected from any 

 worker who had not made a close study of the genera involved. Re- 

 cently the writer was agreeably surprised to find among the material 

 from the National Museum a specimen labeled "Capsus strigulatus 

 Walker" in Uhler's handwriting, rei)resenting the same variety of 

 pratensis which the writer had recognized as strigulatus Walker!
