will very likely prove to be a distinct species when sufficient material is at 

 hand, but with the small amount of widely-scattered material available at 

 present it was thought best to refer it to Titusi as a variety. 



Thamnotettix gloriosa, n. sp. 



Form of visalia nearly, larger, longer, golden iridescent-green, with 

 long flaring elytra, slightly smoky tipped. Length, 6 mm. 



Vertex slightly obtusely angulate, a little over half wider than long, 

 rounding over to the rather flat, strongly-retreating face. Front slightly 

 longer than in visalia, the margins curving in to the clypeus. Elytra very 

 long, inclined to be flaring posteriorly, giving the whole insect a long, 

 parallel margined appearance. 



Colour : Vertex straw-yellow, inclined to be tinged with orange in the 

 males ; face pale creamy-yellow in the female, lemon-yellow with the 

 genae lighter in the male, a black dot just outside the lorse, Pronotum a 

 yellowish-green, darker on the disc. Scutellum pale yellowish-green. 

 Elytra yellowish-green on the clavus, corium subhyaline-yellow, with the 

 tawny tergurn showing through, giving a golden tinge to the whole elytra, 

 the tip inclined to be smoky-iridescent. Below pale. 



Genitalia : Female segment not quite as long as its basal width, the 

 lateral margins parallel, posterior margin with the median third angularly 

 excavated half-way to the base, the excavation slightly narrowing towards 

 the bottom and usually with a slight median projection, the base of the 

 segment below the excavation gibbous, and shining black in colour. Male 

 valve wide, the median half produced into a large triangle, plates rectan- 

 gular, together almost twice wider than long, transversely convex, their 

 apices curved upward and slightly produced at the suture, apical margins 

 thick and with a subapical row of bristles. Extending slightly below the 

 plates a pair of stout, black hooks are visible. Described from eight 

 examples from Tia Juana, California, collected by the author. Specimens 

 varying slightly in the genitalia of both sexes are at hand from Salinas and 

 Ontario, California. 



Thamnotettix gemella, n. sp. 



Form and general appearance o{ languid a nearly, but much smaller 

 and lacking the black spots. A slender green species, with the margins 

 smoky. Length, female 5 mm.; male 4 mm. 



Vertex very obtusely angled, one-fourth longer on middle than 

 against an eye, one-half as long as the basal width, disq convex, broadly
