CHARIESSA I.EMBERTI. 



BY J. J. RIVERS. 



Chariessa Eemberti 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 

 antennae, 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 antennae being red, and hy 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. 

 Eembert, who kindly presented it to me.
