THE CANADIAN ENTOMOLOGIST 199 



Vertex slightly obtusely angled, the apex pointed, conical, half longer 

 on middle than against the eyes, as long as the pronotum, slightly longer 

 than its basal width, disc slightly sloping, anterior margin rounding to the 

 full front except at the apex. Front and clypeus as in belli. Elytra long, 

 inclined to be flaring posteriorly. Venation regular, but often obscured 

 by numerous irregular reticulate veinlets on the clavus and in the ante- 

 apical cells. 



Colour. — Vertex pale, heavily washed with rusty brown, usually omit- 

 ting a pale band before the eyes and often intensified as an oblique 

 brown-dash either side the pointed apex. Face pale, with short brownish 

 fuscous arcs and still darker sutures. Pronotum rusty or chocolate 

 brown, with an anterior arcuated submarginal line paler. Elytra rusty or 

 chocolate brown, with the nervures lighter, the irregular reticulations are 

 usually strongly milky white and there is usually an oblique subhyaline 

 light area beyond the middle of the costa. The apical cells smoky, with 

 the nervures light. 



Genitalia. — Female segment long, truncate or slightly concave pos- 

 teriorly, with a broad angular median emargination, from which arises a 

 strap-shaped tooth considerably exceeding the segment. Male valve 

 triangular, apex round, plates strongly transversely convex, long, attenuate 

 with the margins thickly beset with long hairs. 



Described from four females and one male from San Francisco, 

 collected by the author in September. The reticulate venation and white 

 nervures will readily separate this species from any other described. 



Thajjmotettix rupinata, n. sp. 



Form and general appearance of iniricata, but lacking the super- 

 numerary veinlets. Reddish or greenish brown, with a bisected black 

 spot on the apex of vertex. Length, 5 mm. 



Vertex slightly obtusely angular, the apex rounding, half longer on 

 middle than against either eye, as wide as its median length in the female, 

 narrower in the male, face long and narrow as in intricata. Elytra long 

 and narrow, inclined to be closely appressed in the male, with the tips 

 flaring, venation typical, regular, without extra veinlets. 



Colour. — Vertex orange yellow, a large semi-circular black spot on 

 the apex, bisected by the narrow, white median line, face pale, with nar- 

 row sutures and traces of arcs brown. Pronotum greenish or reddish 

 brown, with a pale anterior margin, accentuated in the centre. Scutellum 

 pale yellow, the basal angles olive. Elytra olive subhyaline with a reddish
