The imagoes have boon reared from nymphs of the third instar found 

 on alfalfa the first week in Jime, ]jut these imagoes refused to oviposit in 

 the laboratory. In the field the eggs are laid in the base of the stem and 

 in the upper parts of the roots of alfalfa, sweet clover, or goldenrod. These 

 eggs winter over in the above-named parts of the plants, which persist 

 from one season to another. Specimens of this species collected at Saranac 

 Lake, New York, on August 26, 1916, were found abundantly on both 

 goldenrod and thistle, in the stems of which plants the eggs were found at 

 that date, together with manj^ evidences of former egg masses and of 

 egg slits of the past season. At Saranac Lake, also, the species was 

 attended by ants, which is not true of the local forms. 



Apparently some adults winter over, for mature specimens have been 

 collected as early as Mny 1, long befoi-e it would be possible for eggs to 

 hatch and nymphs to mature. The nymphs of the first three instars are 

 rarely seen and it is not known where they secrete themselves; but nymphs 

 of the last two instars begin to appear commonly about the middle of June, 

 and by the first of Jul}^ the adults are numerous. 



Technical description. — Uniform cinnamon brown, densely punctate, sparingly pubescent; 

 single porrect pronotal horn projecting forward over head; head and first two pairs of legs

 punctate, densely pubescent; eyes prominent; ocelli small, pearly, equidistant from each other 

 and from the eyes and situated on a line passing thru centers of eyes; clypeus very broad, 

 shining, scarcely punctate, broadly truncate at apex, tip strongly pubescent. 



Prothorax produced anteriorly into a long, flattened horn, ridged in center and foliaceous 

 above and below, varying greatly in length and degree of curve; posterior process strong, 

 tectiform, reaching internal angles of tegmina; median dorsal carina strong and percurrent; 

 entire pronotum concolorous, hghtly punctate, sparingly pubescent with golden hairs; median 

 lateral ridge reaching lateral margin. 



Tegmina yellow-opaque; basal and costal areas punctate and pubescent; veins distinct, 

 broad, and slightly pubescent; five apical and two discoidal cells; hind wings iridescent. 

 Two anterior pairs of legs broadly spatulate and lightly pubescent at margins; posterior 

 tibiae armed with black-tipped spines; tarsi much produced and lighter in color. Under-
