Scaphoideus scrupulosus Ball. 
Canadian Entomologist, Vol. XXXIV, p. 14. 
This species is somewhat out of place in the genus Scaphoideus, 
but can not readily be referred to any other genus. The head 
characters agree distinctly, but in the appearance of wings and 
other features it is more like that of Eutettix. In the description 
by Professor Ball he says it is similar to blandus and jucundus in 
form, the elytra more flaring, and with the general appearance of 
Eutettix, except for the sharply angled vertex, a brown band on 
the base of the elytra, another on tip, and a triangular saddle on 
the disc. Length five millimeters; width 1.25 millimeters. Pro- 
fessor Ball’s specimens were from Los Angeles, Cal., and I have 
one specimen from Sonoma Co., California, so that the species 
appears to be limited to that region. 
Scaphoideus irroratus n. sp. 
Somewhat resembles scrupulosus, but more distinctly irrorate 
and with the female ventral segment without any median appen- 
dage. Length 9 5 mm. 
Vertex distinctly angular, nearly twice as long at center as next the 
eyes; the front rather broad, narrowing but little to the elypeus; the clypeus 
narrowing at base, widening slightly to the tip; the lorae rather large, oval, 
approaching the border; cheek distinctly sinuate under the eye; pronotum 
short, distinctly arched in front, slightly emarginate behind; elytra with 
numerous veinlets. 
Color, fulvus and brownish, distinctly irrorate with fuscus on the pro- 
notum and elytra; vertex tawny with indefinite transverse brownish irrora- 
tions; face without spots but with front suffused with fulvus; pronotum and 
scutellum about equally marked with brownish irrorations; the elytra with 
the irroration following the transverse veinlets and brown spots massing so 
as to form a rather indefinite saddle in front of the middle, and a transverse 
broad band on the apical third, leaving a rather clear space crossing the 
apex of clavus and reaching the costa; the costal cell with about three 
transverse veinlets; the post nodal cell with about six transverse veinlets 
bordered with fuscus; beneath brownish, tibiae and tarsi spotted with 
black. 
Genitalia, last ventral segment of the female longer than the preceding 
and very slightly produced at center; ovipositor reaching the tip of pygofer; 
pygofer with short cilia next the border. 
Described from a single female specimen from the University 
of California campus, Berkeley, from the Department of Ento- 
mology of the University of California. This species, while 
somewhat resembling scrupulosus and differing from typical 
Scaphoideus, presents the head characters of the genus, although 
the antennae are shorter than is the general rule with the genus.
