Euchaeta propinqua n. sp. 



PI. 9, fig. 9; pi. 10, figs. 30, 33. 



Female: Approaching E. calif ornica in general. The shape 

 of the head in lateral view is different, the frontal eminence being 

 lower and hardly visible: the rostrum is shorter and heavier (PI. 

 9, fig. 9). The genital segment is symmetrical, and has the flanges 

 guarding the orifice, as in E. calif ornica, but they protrude much 

 farther ventrally and there is a knob-like swelling behind, be- 

 tween them (PI. 10, figs. 30, 33). The segment is not so swollen 

 laterally as in E. calif ornica. The terminal joint of the anterior 

 antennae is longer in californica than in prop'nqua by one-fifth 

 the length of the joint in the latter; and the terminal joint in 

 projyinqua exceeds the next by almost one-sixth the length of the 

 former, or one-fifth the length of the latter. First foot as in E. 

 californica. In the second foot the marginal bristle of the second 

 joint of the outer ramus does not reach the end of the first mar- 

 ginal of the third joint, nor does the second marginal of the third 

 joint reach the base of the third marginal by about the length of 

 the latter. (In californica the second marginal reaches to the end 

 of the third.) 



Length : Female, 9 mm. 



Coloration : Rather opaque, no pigment in antennae ; red in 

 the mouth parts and feet, including the bristles, and in the body 

 immediately adjacent to the mouth parts. 



Occurrence : One female on the winter trip to San Clemente. 

 Type in the collection of the University of California. 



Euchaeta tenuis n. sp. 



PI. 9, fig. 12; pi. 10, figs. 29, 31. 



Female: Eminence on forehead slightly protruding (PI. 9, 

 fig. 12). Sides of last thoracic segment rounded, sparsely pubes- 

 cent (PI. 10, fig. 29). Genital segment with a long flap guarding 

 the orifice on the right ; the segment is otherwise symmetrical 

 (PI. 10, fig. 31). The second terminal bristles of the furca are 

 much longer than any of the others. Anterior antennae reaching 

 the end of the furca ; the last joint is longer than the preceding
