Platylygus grandis new species.—Distinguished from luridus by its very 
large size, otherwise very similar in general structure and coloration; the 
male genital claspers and saw-toothed chitinous tip of the penis are dis- 
tinctive of the species. 
3. Lengthomm., width 3.36 mm. Rich yellowish brown in color (cock- 
roach brown), translucent shining, narrow basal margin of the pronotum 
and the tip of the scutellum white. Head, sides of the body, femora, 
apical half of the antenne more or less reddish brown; cuneus and cell 
veins reddish as in luridus. A chitinous saw-toothed blade at the tip of 
. the penis and the shape of the right genital clasper with heavy claw (Fig. 
3), distinctive of the species. 
°. Length 8.9 mm., width 3.5 mm., very similar to the male in coloration. 
This species was collected in company with intermedius on the pines at 
the top of Mt. Lemon. 
Holotype: 3, July 26, 1917, Mt. Lemon, altitude 9,000 feet, Santa Cata- 
lina Mountains, Arizona (H. H. Knight); Cornell University Collection. 
Allotype: Taken with the type. © 
Paratypes: 34,5, taken with the types. 6,2, July 30, 1915, Glen Alpine

blackish color; genital claspers and chitinous tip of the penis distinctive 
of the species.

darker. Male genital claspers and chitinous tip of the penis (Fig. 4) dis- 
tinctive of the species. 
®. Usually lighter colored than the male but otherwise very similar. 
This interesting species was taken on pines at the top of Mt. Lemon in 
company with certain species of Camptobrochis, one of which it simulated 
very closely in coloration.
