d as it is found in all stages in midsummer, it is probable that 
least two or three broods occur. Its resemblance to the chinch- 
I g has led to many errors, although it could not possibly be mis- 
ien for its more destructive relative by any one who remembers 
3 peculiar white X-shaped blotch on the back of the latter. The 
incli-bug has also a decidedly black head and thorax, while the 
called “false chinch-bug”* * is of a nearly uniform pale or tarnished 
own color.

This species was first described by P. R. Uhler in 1872 in the 
eliminary Report of the United States Geological Survey of Mon- 
na and Adjacent Territories, from specimens obtained in Colorado, 
though it was said also to inhabit Dakota and Canada, and has 
ice been ascertained to occur in California, Kansas, etc. 
Prof. Riley’s description (from which the following is somewhat 
ndensed) was published in his Filth Report as State Entomologist 
Missouri, in 1873, under the name of Nysius destructor, and re¬ 
lated under the same name in the supplement to his report, in 
81,t Riley’s and Filler’s species having been maintained as dis- 
lct until now. In reply to a recent letter of inquiry, Mr. Uhler 
rites me under date of February 18, 1884: 
“A very close comparison of Riley’s Nysius destructor with my N. 
| igustatus, (Hayden’s Report on Montana, p. 406,) induces me to place 
as a synonym of the latter. There are only minor variations of color 
id structure to separate them. But I now have long series of 
>th extremes with intermediate varieties from many localities— 
est and North.” 
Little has been added to Prof. Riley’s original account of the 
ibits and injuries of the species. 
Larva .—“Dingy yellow, with more or less distinct longitudinal dark 
lies, especially on head.” 
Pupa. (Plate X, Fig. 5, b.) “Same color, with more distinct red 
id brown longitudinal lines, and two little tooth-like pale yellow 
[rocesses at inner base of hemelytra pads, indicating the wings; the 
idomen paler than the rest of the body.” 
Imago. (Fig. 5, c.) “General color grayish brown. Head more or 
ss distinctly pubescent; the surface usually brown, with a distinct 
Lack, longitudinal line each side, broadening on the crown, but 
Bnerally leaving the orbit of the eyes pale; these lines sometimes 
tore diffuse and occupying the whole surface, except a median 
rown spot at base of crown, and a narrow, paler spot on the clypeus; 
Belli piceous; rostrum piceous, paler at the base and reaching to 
ind coxae; antennae either pale yellowish brown or darker brown, 
le torulus and first joint darkest. Thorax with the pronotum 
i arrowing anteriorly, the sides slightly sinuate, irregularly and more 
)arsely punctate than the head, more or less pubescent, dingy 
ellow or brown, with a transverse black band near the anterior 
Ige; also five more or less distinct longitudinal dark lines, the 
*This vernacular name had been applied to another common species by Fitch (his 
ntkocoris pseu o-chinche , which is now called Triphleps insidiosus. Say), long before 
ilcy used it for this; but as it seems more appropriate to this species, I have allowed it
