O AMERICAN XKUKOFTERA. 



vein : a curved black mark from end of anal vein upward and outward, another 

 mark along one of cubital branches toward the preceding mark, nearly meeting 

 to form a semi-circle, and enclosing one or two black spots; an oblong black 

 mark at pterostisrina, and an oblique band in apical part of wing parallel to the 

 apical marsiin. In hind wing the venation is marked with black, there is a 

 rounded black spot at the pterostigma, and a small elongate one near apex. Ex- 

 panse 54 mm . 



One specimen tVuni B<niKler, Colorado, Jnly 31st (^Oslar). 



Differs from D. obsoletum in that there are a great mauy more 

 small spots in the wings, and the large ones are not as large, as well 

 as in coloration of legs, head and thorax. 



I'anorpa earoliiieiisis Bks. — Head yellowish, black around ocelli; 

 autenn:e brown ; thorax brownish yellow; abdomen and legs yellowish. Wings 

 hyaline whitish, with black bands and spots as follows: an apical band, a broad 

 pterostigniatical band, nearly touching the apical at each margin, and with a 

 pale spot on the posterior border, where the band is broader than elsewhere, a 

 large triangular costal spot near middle of wing, and extending almost half way 

 across it. a broad ^not geniculate) sub-basal band, and a costal and anal spot 

 black; venation dark. Wings slender, the subcosta reaches pterostigma in fore- 

 wiugs; in the male the 5th segment has a distinct horn above. Length 15 mm. 



One ni:de from Black Mt., Xortli Carolina (Beutenmiiller). 



Probably nearest to P. rufa, bnt the wings are less elongate, and 

 membrane not yellowish, nor venation pale in pale areas; tiie bands 

 are broader, and not geniculate as in that species. 



PauorpodeN oaroliiieiisis Bks. — Pale yellowish ; a little black around 

 ocelli; antenme black, except joints one and two; legs without dark marks; 

 abdomen dark above on basal two-thirds; tip of the claws of genitalia dark; 

 wings flavescent, with yellowish longitudinal veins and white cross-veins. Face 

 short, triangular, a stout tooth below each eye, extending from cheek ; wings 

 rather narrow, the subcosta runs into the pterostigma ; abdomen slender, seg- 

 ments not modified, except the last, which is similar to that of Panorpa. The 

 prothorax has four long black bristles above, and there are two on each side of 

 the mesothorax. Length 16 mm. 



One male from Black Mt , North Carolina (Beutenmiiller). 



Agrees with P. oregonensis McLach. in many particulars ; but 

 has darker antennoe, and the terminal abdominal segment has 

 longer claws, each with a strong basal tooth, and the median piece 

 that projects below, when seen from the side, is shorter, and has a 

 concave upper margin. 



I'olpotaiuliiiM iiiedialis n. sp. — Head rufous, with some yellowish 

 bristles, vertex with a short black mark on middle behind; palpi yellowish; 

 antenna; yellowish red, including basal joint; prothorax large, two and one-half
