18 AMERICAN NEUROPTERA. 



tion to cubital, and one on forking of lower branch of median and extending 

 upward to the anastomosis. Fringe at outer apical angle rather long and black. 

 Hind wings dusky, darkest at tips, fringe blackish and quite long on hind mar- 

 gin. The forewings are rather slender, the apical margin oblique ; the discal cell 

 is more than twice as long as broad and ends under base of i)terostigma, the api- 

 cal cells much longer than width of wing at widest part; the upper branch of 

 radial sector forks just under tip of pterostigma ; the forking of lower branch of 

 median is under the anastomosis, that of upper branch one-third the way out. 

 The abdomen of the female shows on the under side near tip two prominent me- 

 dian spines, arising from the second and third segment before tip. Expanse 24 

 mm. 



One specimen from the Huachuca Mountains, Arizona, August 

 22n(l, 8000 feet (Oslar). 



Wormaldia inediana n. sp. — Head brown, with yellow hair; ocelli 

 small, but distinct, a dark brown, obliquely transverse wart each side on vertex, 

 palpi dark brown, last joint slightly longer than preceding, and a trifle curved ; 

 antennfe yellowish, brown toward tips; prothorax dark brown; thoiax paler 

 brown, all with yellow hair; abdomen brown above, yellowish beneath ; legs pale 

 yellowish, with brown spurs. Wings brownish, sparsely clothed with short 

 golden hair, the anastomosis and the veinlet connecting median to cubitus at base 

 of thyridial cell are hyaline-white; venation brown; hindwings dusky, with 

 gray hair and fringe. In forewings forks 1 and 2 reach discal cell, fork 3 long- 

 pedicellate, fork 5 not reaching connecting veinlet to median ; a straight cross- 

 veinlet in middle of costal area, and an oblique cross-veinlet from discal cell to 

 radius. Length 7 mm. 



One specimen from Chinandega, Nicaragua (Baker). 



XOTIOMYIA n. gen. 



A Leptocerid ; spurs 2-4-4; palpi upcurved ; basal joint of 

 antennae rather short; no ocelli ; discal cell of forewings very indis- 

 tinctly closed, if at all ; a long furrow through the forewing much 

 as in Scelis. Venation as figured. 



Type. — N. mexicana Banks (sub Heteroplectron). 



Motioniyia mexicana Banks. — Black throughout, except the abdomen 

 and the prothorax above and below which are reddish yellow. Antennse nearly 

 twice as long as the wings; vertex long, with a median carina, a crest of bristles 

 above base of antenna;, an elongate wart each side near posterior margin crowned 

 with erect bristles, elsewhere the vertex is smooth. Legs rather long, spurs 

 rather short, the preapical pair on middle tibiae at about middle, those of hind 

 tibiai near end of second third ; hind tibise scarcely as long as femora, middle 

 tibiie much shorter than femora; basal joint of hind tarsus as long as rest of 

 joints together. Wings clothed with black hairs, and in ai)ical part many small 

 glittering scale-like liairs; the furrow in forewings furnished with black hair. 

 Expanse 2(j mm.
