308 THE ENTOMOLOGIST. 



tudinally ridged, bounded behind by more or less of a rim ; tegulae 

 piceons ; wings smoky hyaline, barely darker at apex ; nervures and 

 stigma piceous ; legs black; abdomen shining, rather finely but 

 strongly and closely punctured ; dorsal surface of first four segments 

 practically nude, except for a well-marked patch of white hair on the 

 lateral margins of the second to the fourth, some scattered glistening 

 yellowish hairs across the middle of the third and fourth, and an 

 indistinct fringe of very short liairs on the extreme margins of the 

 second and third ; fifth segment and apex clothed with orange-fulvous 

 hairs ; ventral segments with rather long fringes of white hair. 



Hah. Olympia, Washington State, June 18th, 1895 (T. 

 Kincaid). 



A. grandior is related to A. rugosa, but it is larger, and the 

 stigma is quite differently coloured. The base of the meta- 

 thorax is similar in the two species. 



(6.) Andrena striatifrons, n. sp. 

 ? . Length 111 ^^j^. ; black, with moderately long and dense 

 fulvous pubescence. Belongs to Robertson's second group. Facial 

 quadrangle slightly broader than long ; lateral facial depressions with 

 appressed pubescence ; clypeus hairy, but surface visible, shining, 

 closely and strongly punctured, 7(o smooth line; fruut below ocelli stromjhj 

 lon(jitudinaU]i striate; vertex dull, with shallow obscure punctures; 

 flagellum wholly dark ; mandibles dark ; basal process of labrum 

 broad and rounded at end ; mesothorax rather dull, with very large 

 and close punctures, lacking in the centre ; scutellum shiny, with very 

 large punctures ; sides of metathorax strongly rugoso-punctate ; the 

 enclosure strongly longitudinally wrinkled, bounded behind by a sharp 

 edge ; tegulje piceous ; pubescence of thorax a lively orauge-fulvous ; 

 wings hyaline, faintly clouded at apex ; nervures and stigma ferru- 

 ginous ; in the type specimen there are on one side only two sub- 

 marginal cells, on the other three, but even here the second transverso- 

 cubital nervure is incomplete below ; legs black, with pale fulvous 

 pubescence, hind tibite ferruginous suffused with black, hind tarsi 

 ■whollij ferruginous ; abdomen &\\in\ng, punctures scattered, minute and 

 hardhj visible, except the bases of the scfiiiumts, which are rerij distinctly 

 tlumgh rather sparsely punctured ; second to fourth segments with lateral 

 patches of pale fulvous hair, representing very broadly interrupted 

 bands; fifth segment clothed with fulvous hair at apex and sides; anal 

 fimbria dark rufous. The longitudinal wrinkles of the metathoracic 

 enclosure, while strong, are much weaker than those of grandior, and 

 the intervals between them are granular.

(7.) Andrena macgillivrayi, n. sp. 



? . Length 10 mm. ; black, pubescence fulvous on occiput and 

 thoracic dorsum, otherwise whitish or dull white. Facial quadrangle 

 somewhat broader than long ; lateral facial depressions with appressed 

 pubescence ; sides of face and area between antennae with long pale
