obscurely transversely striate. Basal joint of antennae surpas- 

 sing tip of clypeus by nearly half its length; second slender, 

 about four times the length of first; third and fourth together 

 nearly a-s long as second, fourth about equal to first. Rostrum 

 reaching on the third ventral segment in the female, to the fifth 

 in the male, first joint surpassing base of head. Pronotum nearly 

 flat and horizontal, the surface before callosities .scarcely de- 

 pressed, anterior edge with a slight median sinus; sides straight, 

 subcarinate. Scutellum equilateral. Elytra elliptical, nearly flat, 

 cuneus scarcely longer than broad ; abdomen reaching to middle 

 of cuneus in the male, nearly to apex of membrane in the female. 

 Membrane surpassing cuneus by about one-third its length. 



Male genital pieces large ; dextral hook very large and curved 

 in conformity with the margin of anal opening, in form ligulate, 

 its subacute tip reaching over onto apex of tergum; sinistral 

 almost eciually long and similar in form, produced either way 

 and lying parallel with and just below the dextral, its inner end 

 obtuse, the outer acute. Female pygofers short, beginning behind 

 middle of venter, hind edge of fourth segment almost straight 

 across. 



Color pale green, becoming yellowish on head, pronotum, legs, 

 antennae, and lower surface in dried specimens. Antennae in- 

 fuscated toward apex. Tibial bristles fuscous; apex of tarsi 

 black. Vestiture composed of a fine soft pubescence and short 

 stiff fuscous hairs intermixed. Membrane nearly hyaline, 

 nervures green. 



Redescribed from five male and three female examples taken 

 in San Diego County, California, at Alpine, IMussey's, and Fos- 

 ter's, from April to June. 



Macrotyloides apicalis n. sp. 



Closely allied to the preceding; a little shorter behind, with 

 apex of membrane deep smoky brown. Length 5.5 to 6 nun. to 

 tip of the membrane. 



This species is very close to the preceding in most of its 

 characters, but the elytra are shorter, making the insect appear 

 broader; tibial bristles shorter and more slender, and the basal 

 joint of the rostrum scarcely passes the base of the head. Oviduct 

 of the female longer, beginning distinctly before middle of venter, 

 with fourth ventral segment strongly oblique, not practically 

 tran.sverse as in vestitus. Color light green, becoming yellowish 

 on head, pronotum, and below, as in vestitus. Antennae infus- 

 cated at apex. Membrane whitish-hyaline with its apex beyond 

 the tip of cuneus abruptly blackish-fuscous.
