between e3'es (20 to 19); rostrum extending over anterior fourth of meso- 
sternum. Pronotum (fig. 9d) with lateral margins finely erenulate i)ostcr- 
iorly, a few large teeth anteriorly; carinae strongly elevated. Scutellum 
longer than pronotum (35 to 22), structure as in the i>receding except that 
the disc is less strongly depressed. Hemielytra aliout as in the jireceiling. 
(S' (fig. 9b). Fifth ventral segment about as long as sixth; genital segment 
short, moderately convex, the lobes rather long; abdomen broadly obovate, 
widest well behind middle, margins entire. Length, 5.5 mm. 
? (fig. 9a). Posterior margin of dorsal genital segment sinuate, shallowly 
emarginate at middle; genital lobes short as viewed from above; projecting 
a distance less than one-half their breadth; abdomen almost circular, apices 
of the segments a little prominent; connexival segments transverselj’ ridged. 
Length, G mm. 
Ty])e specimen (Berkeley, California) in the collection of the 
California Acadenn^ of Sciences. 
This Californian species, while rather closely related to fusco- 
niaculotus, is well distinguished by the proportions of the an- 
tennal segments, by its genital characters, and, in the typical 
form, by the coloration of the antennae. 
Aradus pannosus variety' incomptus var. nov. 
Like the tj'pical form except in the absence of the apical ring ot the secimd 
antennal segment. 
Ilolotype . — 9; Alarin County, C'alifornia, XI, 8, 1919 (H. 
Dietrich), in my collection. 
Paratypes. — Females; same data as holotype, and XII, 27, 
1919, in my collection. 
This is a well-marked form of true varietal rank, since it occurs 
in the same region as the typical and exhiltits intergradation, 
as indicated Ity one of the paratypes which shows slight traces of 
pale color at the apex of the second antennal segment.
