AMERICAN XEUROPTERA. 157 



1. Horn of male as long as width of vertex ; second and third joints of male 



antenna? simple; no line on cheek in either sex; gradate veinlets 



blackish signoretti. 



Horn of male much smaller ; a black line on cheek 2. 



2. Second and third joints of antenna? of male excavate on inner side; gradate 



veinlets green slossonje. 



Second and third joints simple ; gradate veinlets blackish ililiovala. 



Meleonia signoretti Fitch. — Pale yellowish green. Face of male pro- 

 jecting in front in two reddish submedian tubercles; between antenna? arises a 

 prominent horn which is as long as width of vertex, and projects out horizon- 

 tally, its end bent vertically downward and provided with a stiff bifid brush of 

 pale reddish hair ; in the female this and the tubercle are lacking ; vertex elevated 

 transversely between the eyes. The antenna? are darkened beyond the base, but 

 not black, in length scarcely reaching to middle of wing. Prothorax a little 

 longer than broad, plainly narrowed in front, and with a transverse ridge beyond 

 the middle. Venation of wing green, with the gradate veins blackish, as also 

 the bases of the cross-veins from the radius, and one or two cross-veins in the 

 anal region, lower half of base of third cubital cell and connecting veinlet to the 

 radial sector and end of the divisory veinlet of third cubital cell black. Length 

 14 1(J mm. 



Specimens come from Mt. \Yashington and Franconia, New 

 Hampshire, and from Sea Cliff, N. Y., July; Fitch's specimen was 

 from the Green Alts, of Vermont. The type was, according to 

 Hagen, purchased fur the Museum of Comparative Zoology, but there 

 is a specimen in the National Museum from the old Fitch collection. 



Meleoma slossonse Banks. — Pale green or yellowish when dry, a red- 

 brown stripe from eye to mouth ; palpi marked with reddish, a dark spot on each 

 anterior side margin of pronotum. Venation green, many of the cross-veinlets 

 in part black ; pterostigma long and distinct. In the male there is a cavity in 

 middle of face below antenna?,, between bases of antenna? is a short, broad tuber- 

 cle, trifid at tip ; the vertex is transversely elevated from eye to eye. Antenna? 

 with basal joints slender and divergent, curved, concave within, second and third 

 joints short, fourth longer and swollen at base on inner side. In J there is no 

 tubercle, but a slight conical elevation ; the basal joints of antennae, are simple, as 

 also the fourth. Pronotum broader than long, sides nearly parallel, a little nar- 

 rowed at extreme front. Wings moderately long, anterior pair rounded at apex, 

 hind pair acute at tip. Length 18-19 mm. 



Specimens have been taken by Mrs. A. T. Slosson from Mt. 

 Washington, Crawford Notch and Franconia, New Hampshire; 

 also seen from Brookline, Maine; and Quebec and Sherbrooke, 

 Canada. This species differs much from M. signoretti, in structure 

 of antennae and the tubercle. Mr. McLachlan in a note in Ent. 

 News, 1«S94, thinks that it is a sex of M. signoretti; however, there 

 is not the slightest doubt of their distinctness, and that the female 

 Me/eoma is without a horn.
