jointed in colifornica but entire in saissetiae, and with a few scat-

 crease in length toward the apex. 



GAHANIELLA CALIFORNICA, new species 



Plate 1, fig. 6; plate 2, figs. 15 and 18 



Female. — ^Antennal sockets about equidistant from the ej^es and 

 the oral margin; scape proper about three times as long as wide, 

 pedicel nearly globular, club perfectly oval and rounded at base. 

 Frontovertex somewhat more roughly scultpured than the rest of the 

 head, with the reticulations somewhat thimblelike, the fine pin punc- 

 tures rather numerous; scutellum finely striolate but becoming 

 reticulate at apex, both mesoscutum and scutellum with numerous 

 very minute setiferous punctures seriately arranged; propleura and 

 prepectal plates comparatively coarsely and longitudinally reticu- 

 late, mesopleura finely reticulate, the propodeum smooth. Pubes- 

 cence on head very fine, short, semiappressed, and although rather 

 abundant on the lower part of the face and on the frontovertex, it 

 is hardly visible except under high magnification; pubescence on 

 mesoscutum and scutellum longer, but on account of its dark color 

 it is not conspicuous; the apex of the scutellum mostly bare except 

 for a pair of longer, more erect setae; pubescence of abdomen very 

 fine and dark-colored above, being most abundant along the margins 

 and at apex; the venter also rather densely pubescent with fine 

 appressed hairs. 



Coloration shining black, the frontovertex, thorax above, and the 

 abdomen with a slight greenish luster, the scutellum a little duller; 

 face, cheeks, and under parts of thorax somewhat bluish, mandibles 

 brown; antennae brownish, the scape except the radicle and the 

 pedicel except apical margin fuscous. Legs brownish to fuscous, 

 the middle and hind femora inclining to brown; trochanters and 

 front tibiae and tarsi yellowish brown; apex of middle femora, the 

 middle tibiae at base and apex, apex of hind tibiae narrowly and the 

 middle and hind tarsi pale yellow, the middle tibiae broadly and 

 rather indefinitely brownish otherwise ; the last joint of middle tarsi 

 and last two joints of hind tarsi brown. Wings hyaline, the veins 

 brownish with the marginal vein darker and more conspicuous than 

 the rest of the venation. 



Length of body, (1.26 to) 1.34; length of head, 0.459; width of 

 head, 0.55; width of frontovertex, 0.254; length of antenna, 0.777; 

 width of mesoscutum, 0.506; length of fore wing, 1.067; width of 

 fore wing, 0.525 mm. 



Male. — Very similar to the female in structure and coloration, but 

 the head much thinner f rontooccipitally, the frontovertex nearly 

 twice as wide as long, the ocelli in an obtuse-angled triangle, the
