nitely fixed in mind. While collecting in another locality last year 

 the same species was found and instantly recognized, and, like the 

 former one, lost. This now became the chief object of search, and 

 later it was captured in several different places. Its remarkable 

 agility in escaping from a net probably being a reason it has not 

 been captured before. 



Thamnotettix pasadena, n. sp. 



Size and form of ursina nearly, colour pattern resembling 

 collaris, but still more highly ornamented. Rich brown, with head, 

 saddle and anteapical band yellow. Length 9 6.5mm; o 71 6mm.; 

 width 1.5mm. 



Vertex definitely obtusely angled, almost two-thirds as long 

 as its basal width, slightly shorter than the pronotum, one-half 

 longer at apex than against the eye, disc flat, the margins rounding 

 to the front except at the conical apex, front broadly wedge-shaped, 

 the lateral margins nearly straight, clypeus broad, slightly con- 

 stricted. Elytra moderately long, strongly flaring behind. Vena- 

 tion weak, often obscure, with irregular reticulations in the ante- 

 apical cells, often especially emphasized along the claval and costal 

 margins. 



Colour — Vertex and face light yellow to yellowish ivory, 

 eyes reddish or reddish brown, pronotum lich brown, the anterior 

 submargin rich brown, with a row of irregular coalescing black 

 spots, on either side a transverse median ivory mark; scutellum 

 rich brown, sometimes with a medium light shield ornamented 

 with two round dots. Elytra with the anterior two-thirds of 

 claval areas rich yellowish ivory, the remainder brown, corium 

 yellowish subhyaline, a brown cloud along the claval suture abruptly 

 terminating just before the apex of clavus, where it expands and, 

 uniting with the claval markings, forms a transverse brown band 

 which narrows toward the costa and becomes slightly oblique, 

 the reflexed apices of the elytra, including most of the apical areas 

 smoky brown. 



Genitalia — Eemale ultimate segment three or four times as 

 long as the preceding, deeply angularly excavated from the lateral 

 angles two-thirds of its depth, the bottom of the notch broadly
