of the vertex, a large arc on either side of the front, some marks 

 on the base and sides of the clypeus and the lorae black. The 

 antennae are black, the second joint as long as the base of the 

 pronotum and one-fourth longer than the third and fourth tcil\en 

 together. The legs are white, with the tibiae dotted with black. 

 The white markings, especially on the head and pronotum may 

 become more or less orange. 



Dextral hook of the male genitalia apparently a flattened 

 truncated scale scarcely longer than broad ; sinistral very large, 

 expanded on the right to base of dextral hook and exteriorly 

 narrowed and curved upward and inward to superior aspect of 

 anal opening. 



I took three examples of this insect from the white sage grow- 

 ing on the mesa at East San Diego, California, during April and 

 May, 1918. 



Pseudopsallus verticalis (Uhler) 



This is a smaller, pale brown or testaceous form, with the 

 head and anterior lobe of the pronotum fuscou.s, the base of the 

 vertex marked with pale, and the legs pale dotted with fuscous.

 taken in Colorado was sent to me by Professor Baker labelled

Argyrocoris femoratns n. sp. 



Smaller and darker-colored than scurrilis; slender ; testaceous- 

 grey, more or less infuscated, cuneus dotted with red. Length 

 4 mm. to tip of membrane. 



Head strongly oblique ; vertex convex, ecarinate ; front moder- 

 ately convex. Eyes large oval, viewed from the side oblique and 

 attaining gula, coarsely granulated. Antennae long; basal joint 

 surpassing head by one-half its length; second over three times 

 the length of first; third and fourth together about equal to 

 second. Pronotum transverse, its length about three-fifths its 

 basal width, anterior margin about two-thirds of posterior ; hind 

 edge depressed, covering basal lobe of scutellum. Rostrum long, 

 reaching middle of venter. Elytra long and narrow; tip of 

 abdomen not attaining apex of corium, cuneus slender, its length 

 nearly three times its basal width in the ma]e. In the female 

 the abdomen reaches to about the middle of the cuneus, which is
