Vol. VII] GIFFARD— CALIFORNIA HEM I PT ERA 313 



344. Stobaera giffardi, new species 



Smaller than tricarinata, most nearly related to bilobata and like that 

 species with a dark elytral stigma ; face variegated ; legs lineated and 

 banded ; elytra maculated, the nervures strongly punctate and bearing stiflf 

 bristles. Brachypterous form, length, male 2pl mm., female 3^ mm. 



Vertex elongated as in bilobata but broader than in that species, the 

 three frontal carinse very prominent at apex of head. Front parallel or 

 nearly so. Second segment of antennje about twice the length of the first ; 

 scarcely narrowed at apex. Pronotum as long as the superior aspect of 

 the head, the lateral carinse strongly angled behind the eyes, then parallel 

 to the hind margin ; lateral carin?e of the mesonotum straight and more 

 oblique than in bilobata. Elytra scarcely exceeding the abdomen ; outer 

 branch of the first sector forked a very little anterior to the forking of 

 the second sector ; all the nervures strong and prominently punctate, the 

 bristles long and stiff. Calcar rather narrow and lanceolate. 



Color testaceous-grey or faintly tinged with brown in the female, darker 

 or almost castaneous in the male. Carinje of the head, pronotum and 

 mesonotum pale, maculated with darker in the male, scarcely so in the 

 female. Face brown, paler in the female, in both sexes darker across the 

 apical half of the front ; a narrow whitish band crosses the face at the 

 lower angle of the eye and a more slender one on the apex of the front, 

 the darker apical portion of the front with a pale crescent ; lateral caringe 

 with two white points between the eyes and on the median is another 

 placed between the lateral ; apex of the clypeus marked with two brown 

 points. Antennpe brown in the male, mostly pale in the female ; sides of 

 the pronotum with a few pale points. Elytra cinerous with faint indica- 

 tions of the dark markings found in tricarinata; stigma small, squarish, 

 nearly black, followed by a transverse white vein. Tergum infuscated on 

 either side toward the base. Legs pale ; coxae, femora and tibiae twice 

 banded with fuscous, the femora lineated with pale brown. Metapleura 

 marked with a large round fuscous spot ; the ventral segments dotted with 

 fuscous points on either side. 



Apex of the male genital segment infuscated much obscuring the 

 genital characters ; plates vertical, broad and appressed, their apex ob- 

 liquely truncated with the outer angle acute and almost spinose ; the stiles 

 covered by the plates. 



Described from numerous individuals of both sexes taken 

 by Mr. Giffard as follows: Portola Valley, San Mateo Co., 

 May 4, 1917; Santa Cruz Co., June 7, 1917; Niles Canyon, 

 May, 1916, May 23, 1917; Yosemite, June. 1916. These 

 were all taken on wormwood. 



This species corresponds in size with bilobata and iiiiiiufa. 

 It agrees with bilobata in possessing a dark stigma and with 

 tricarinata and mimita in the banded legs. In some darkly 

 colored males the elytra are almost entirely fuscous as far as 

 the stigiiia with the costa pale and always the commissural 

 nervure is pale, interrupted with fuscous beyond the scutellum 

 and again at apex. The young are brown varied with whit- 

 ish with the head short, transverse and black above and the 

 antennae and base of the front are also black; in the later
