Jan., 1910.] Remarks on the Genus Scaplioideus. 257 



Scaphoideus scrupulosus Ball. 



Canadian Entomologist, Vol. XXXIV, p. 14. 



This species is somewhat out of place in the genus Scaphoideus, 

 l)ut 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 irroratc 

 and with the female ventral segrnent 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 clypeus; 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.
