April and May. This species has a pecuHar washed-out imma- 

 ture look, which, with its slightly larger size, will distinguish 

 it from our other willow species. 



Type, male, and allotype in author's collection. Paratypes 

 in Museum of California Academy of Sciences (No. 316), col- 

 lection of the University of California and in author's col-

17. Orthotylus farmosus, new species. 



Elongate-ovate, pale green or yellowish, polished, the typ- 

 ical markings reduced ; hind margin of the pronotum slenderly 

 black and there is a black mark behind the callosities. Length 

 7mm. to tip of the membrane. 



Head somewhat oblique, not so nearly vertical as in our 

 other species. Vertex scarcely flattened, the basal carina prom- 

 inent; front broad, convex, polished; clypeus narrow, promi- 

 nent and strongly arcuated. Eyes not very prominent ; viewed 

 from the side, oval, oblique, reaching below the middle of 

 the side of the head. Antennae long, the basal joint longer than 

 the head, surpassing the clypeus by at least three-fourths its 

 length ; second about three and a half times the length of the 

 first. Pronotum long, much narrowed anteriorly, its length 

 two-thirds its basal width. Callosities large, oval, the disk be- 

 hind them rather strongly convex and polished. Scutellum 

 large, its basal lobe well exposed. Elytra long with the costal 

 margin gently arched ; apex of the abdomen reaching to about 

 the tip of the cuneus. Rostrum attaining the apex of the in- 

 termediate coxae. Oviduct of the female long, beginning be- 

 fore the middle of the venter. 



Color a clear pale greenish, becoming yellowish on the scu- 

 tellum, pronotum, legs and lower surface; basal lobe of the 

 scutellum and head fulvous. Antennae and tarsi black, the 

 basal joint of the former dusky green. Hind edge of the pro- 

 notum and an arc behind the callosities which may be ex- 

 tended in a sinuate transverse line, black. Vertex with two 

 subbasal dashes and two minute approximate points before 

 them brown ; the base of the clypeus with a small fuscous spot. 

 Elytra marked with a slender black line next the scutellum and 

 a shorter one on the apical margin at base of the membrane; 

 middle line of the clavus with a long fuscous ray and near the
