Plate x11, fig. 9; plate xxu11, figs. 4-8. 
Type.— 8, University of California, No. 19,511, Pacific Grove, Calif. 
Trunk unsegmented, smooth, short, and broad, especially in front; an- 
terior outer corners rounded, without projecting knobs. Lateral processes 
short and very closely crowded, the lines between them radiating toward 
a common point slightly anterior to the caudal segment. 
Caudal segment well forward, rather short, thick, bluntly conical, 
directed obliquely upward, armed on the dorsal surface with 2 or 3 short 
stiff spines. 
Eye tubercle situated on the middle of the first trunk segment; about 
two thirds as high as caudal segment; conical, nearly straight and vertical 
anteriorly ; sloping behind; thus giving, with the anteriorly directed face 
of the caudal segment and the dorsal part of the trunk segments between 
a saddle-shaped outline when seen from the side. The posterior, sloping, 
face of the eye tubercle is notched, or ‘hipped,’ just above the eyes, the 
portion above being a smaller cone set upon the anterior part of the 
larger truncated basalcone. Eyes close together. 
Proboscis short and thick, barely twice as long as broad, directed 
straight forward, cylindrical, bluntly rounded at the apex. 
Chelifori short, knob-like, connected at the base; armed distally with 
2 or 3 short spines. 
Palpi 4-jointed, not reaching to end of proboscis; nearly straight. 
Joints 1, 3, and 4 short; 7.2 long, half as long as the entire appendage, 
considerably larger at its proximal end than distally; 7.4 with several 
short stout spines distally ; 77.2 and 3 each with 2 or 3 smaller ones. 
Oviger of male about three and a half times as long as palp. First joint 
short, thick; 7.2 longer and more slender; 7.3 equal in length to 7.1; 77.4 
and 5 each about equal to, or slightly longer than, 7.2; 7.6 about as long 
as 7.3; 7.7 considerably smaller, coming off somewhat from the side of 7.6 ; 
77.8 and g slightly smaller than 7.7; 7.10 a very small rounded knob. 
The terminal part of the appendage bears a few scattered weak spines, 
besides 2 longer, stouter, divergent ones on 7.10. 
Legs comparatively stout, anterior pair somewhat over twice as long 
as body (measured from tip of proboscis to distal border of fourth pair 
of lateral processes); posterior legs noticeably shorter than anterior 
pairs. Coxal joints all short and of about equal length; ¢.1 with a more 
or less irregular projection distally on its anterior side, which is armed 
with a few short spines. Femoral joint stout, somewhat shorter than
