straight. 
Length—4 mill.

Habitat, San Diego, California. 
Station, mudflats between tides. 
I collected about twenty specimens of this interesting little

this occasion to add it to our West Coast shells. 
CHARIESSA LEMBERTI. 
BY: J.J. RIVERS: 
CHARIESSA LEMBERTI nov. sp. Form robust, prothorax 
widest across the middle; head and prothorax finely punctate; 
Elytra twice as long as wide, but widening from base to near the 
apex; finely punctured in a faintly longitudinal pattern and cov- 
ered with very short black hair. Color: Head, basal joints of 
antenne, prothorax, legs, all but the tarsi, and the whole of the 
underparts red of a subdued crimson. Size: Variable in both 
sexes from 8-12 mm. 
Has a superficial resemblance to C. elegans Horn, but is dis- 
tinguished by having its thorax flatter and wider, by the legs 
being red instead of black (except the tarsi), by the basal joint 
of antenne being red, and by its prothorax not bearing a polished 
surface, as in C. elegans Horn, and the insect is altogether a 
wider species. Habitat: Yosemite. Collected by Mr. J. B. 
Lembert, who kindly presented it to me.
