Rhinacloa forticornis, Reut. 



Beaten from scrub oak ( Q. undulatus, var. IVrightii), May 24, in 

 Soledad Canon. It is blackish or brownish, variegated with pale yellowish 

 or silvery. Also beaten, May 28, from alfalfa. 

 Halticotoma valida, Uhler. 



This is a stout looking, short capsid, bluish-black in colour, with the 

 head and thorax reddish-brown. It was found very numerous from May 

 15 to June 2, on leaves of both Yucca august if olia and Y. macrocarpa (?). 

 They do not fly readily, but run down to the base of the leaves and are 

 thus hard to catch. Both adults and young were found, May 15, 

 puncturing the leaves. The larvae are also bluish-black in colour.

Both adults and larvae of this capsid were found on mesa April 4 

 infesting plants of Senecio douglasii, which they puncture. Both larvae 

 and adults are greenish. Plant determined by Prof. Wooton. 

 Tuponia herbacca, Uhler MS. 



This small, light green capsid was beaten from mesquite ( P.JuliJlora),

 swept from alfalfa, which I cannot distinguish from this species.
