subequal, the third about equal to the basal one. Autennse very slen- 

 der, setaceous, long, the basal joint cylindrical, not thicker toward 

 the tip, and very indistinctly thickened near the base, about as long as 

 the head and pronotum united, pale yellow, mottled and obliquely 

 banded with brown, and dark fuscous at tip ; the second joint one grade 

 more slender, evenly filiform, a little more than twice the length of the 

 first, brown, banded at base and on the middle with pale yellow ; follow- 

 ing joints very slender, shorter, dark brown, the base of third pale. 

 Pronotum gray or pale brownish, sprinkled and spotted with darker 

 brown, clothed with hoary pubescence (or sometimes with the hairs 

 ocherous), having the wavy posterior submargin marked with a black 

 line, the center of which is triangularly emarginate and connected with 

 a longitudinal impressed line, the margin depressed and whitish; col- 

 lum whitish or pale yellow, marked each side with light brown; hu- 

 meral angles a little prominent; sternum and middle of venter whitish 

 almost to the tip, the pleural pieces and sides of venter fuscous, or paler 

 brown, the latter and sometimes the two or three last segments mottled 

 with brown. Legs and coxte pale yellow, long and slender; the femora 

 spotted with brown in uneven series, particularly near the tip ; the fore 

 and middle tibiae thrice banded, and the posterior tibiae mottled with 

 brown ; tarsi more or less brownish, with the tip darker, including the 

 nails. Hemelytra licheuated, on a pale ground, with gray, fuscous, or 

 greenish ; the costal margin, nervures, and apical margin with brown 

 interrupted lines; clothed with almost prostrate grayish or yellowish 

 pubescence; membrane fuscous or brown, marbled with pale yellowish 

 or white, the veins ferruginous. Tergum pale brown, more or less 

 clouded with dark brown. 



Length to tip of venter 5-6 millimeters. Width of base of pronotum 

 2 millimeters. 



This is an exceedingly neat species of PhytoeoriSj of which I found 

 specimens on small plants in Beaver Brook Gulch, next to Clear Creek 

 Caiion, on August 6. It is quite common in Eastern Massachusetts, in 

 Lower Canada, in Ehode Island, New Jersey, Texas, and Maryland. In 

 the vicinity of Baltimore, I have swept it from umbelliferous plants in 

 damp situations, and on dates ranging from June 26 to September 19. 

 When at rest, it looks so much like some of the species of the Neurop- 

 terous genus Psocus that on one or two occasions I had nearly passed it 

 by, mistaking it for that insect. 



The less mature examples are Of a paler, more ferruginous brown, 

 marked with pale yellow and darker brown ; and varieties occur in the 

 South which have lead-colored or bluish markings near the tip of the 



corium.
