AMERICAN NKUROPTKKA. 261 



veinlet is barely if any beyond tiie precediug veinlet, tlie costal space is only 

 moderately broad at base; in the hind wings the foik of the radial sector is 

 plainly before fork of median vein. Expanse 20 mm. 



Speciinetis from Lake Placid, New York, August 12tli ; Peru, 

 Mass., August 26th, and ]Mt. Katalidin, Maine. 



By position of posterior veinlet of inner gradate series, and mod- 

 erate costal area it is allied to H. slir/mnterus, hut the shape of 

 appendages, es[)ecially tiie lower ))art, separates it from that species. 



Ileinerobiii*^ alpe.striM n. sp. — Face yellowish, with a transverse black- 

 ish band below antenna-, extending down each side to the clypeus, cheeks dark ; 

 antennse pale yellowish, the basal .joint brown, beneath pale, prouotum brown- 

 ish ; thorax yellowish-brown ; abdomen nearly black, with long golden liair near 

 tip above ; legs pale yellowish. Wings faintly biownish, venation brown, inter- 

 rupted with white, no large brown spots on wings, but the posterior and outer 

 margins are broadly brown, more distinctly brown than rest of surface, indistinct 

 clouds over each gradate veinlet; hind wings pale, stigma rather yellowish. 

 Forewings rather short and broad, costal area moderate, last veinlet of inner 

 gradate series slightly beyond preceding, the median is not bent toward the 

 cubitus at the connecting veinlet, which is nearly as long as veinlet to anal ; 

 three radial sectors; in the hind wings the radial sector forks beyond fork of 

 median vein. Expanse 13 mm. 



Sugar Loaf Mountain, Colo. (8,500 ft.). May lotii. Mr. Rohwer. 



Sisyra apicalis n. sp. — Face yellowish, vertex dark brown, both with 

 golden hair; antennse yellow-brown on basal joint, jet black beyond for nearly 

 two-thirds of its length, then pale yellowish to near the tip which is black ; 

 thorax brown; eoxte brown, rest of legs pale yellowish; abdomen blackish. 

 Wings fumose; veins brown, and a brown streak through each cell. Wings 

 slender; about seven costal cross-veins, all near base, radial sector with three 

 branches and connected back to radius twice, the first three veins beyond end of 

 radius are forked only near margin of wing, the next three are forked near mar- 

 gin and also about one-third the distance across wing. Length ii mm. 



Havana, Cuba (Baker). 



Distinct from ^S'. vicarl.a by smaller size, more slender wings, fewer 

 costal cross-veins, by colors of antennae and minor points. 



PANORPID^E. 



BiltaciiN tcvvaniis n. sp.— Eather reddish-yellow, ocelli on black, hind 

 tarsus brown ; wings more rufous-brown than in other species; in color similar 

 to B. mcxicanus, the costal apex of the wings being darkened as in that species; 

 legs immaculate. Antenna- minutely pubescent ; iiind femora swollen on basal 

 part as much as in occidentis, but the joint is much longer. Male genitalia on the 

 plan of B. stigmateriis, but the superior ajjpendages are twice as long as the tenth 

 ventral segment, the tip rounded, hairy, the ujijier edge barely concave, humped
