THE JUMPING TREE BUGS. 655 



corium, with commissure as long as scutellum ; elytra slightly 

 surpassing abdomen, costal margin feebly curved, rather broad- 

 ly flattened and reflexed. One species occurs in our territory. 



630 (1273). Myiomma cixiiformis (Uhler), 1891, 121. 



Elongate-oval. Dull black; head pale, brownish-yellow; base of 

 cuneus with a somewhat calloused ivory-white crossbar; membrane fus- 

 cous-brown; legs, beak and under surface dark chestnut-brown, shining; 

 tarsi and tips of tibiae dull yellow. Joints 1 and 2 of antennae blackish, 

 1 very short and stout, 2 stouter, as long as vertex and pronotum united 

 (fig. 5) ; 3 and 4 fuscous, very slender, united shorter than 2, 4 fusiform, 

 pointed, two-thirds the length of 3. Upper surface except membrane 

 finely scabrous, sparsely punctate, each puncture bearing a very short 

 fine hair. Length, 2.3—2.5 mm. (PI. VIII, fig. 4). 



Falls Church, Va., July 20 (Banks) . Ranges from Long 

 Island, southwest to West Virginia. It is said by Heidemann 

 to "live in damp and shady places on the twigs of dead trees ;" 

 while McAtee found it on the barkless surface of a hackberry 

 limb which was covered by a thin velvet-like growth of fungus. 

 Uhler (loc. cit.) states that: "It is remarkable for having the 

 head pressed back upon the sternum as in the Homoptera and 

 its general figure distinctly recalls the form which prevails so 

 commonly in many of the Ci.viidcc." 



II. Corticoris McAtee & Malloch, 1922, 95. 



Small rather broadly ovate species, having the head, viewed 

 from above, very short, depressed, rounded in front ; beak 

 reaching to or beyond second ventral ; antennae inserted on 

 under side of head, somewhat distant from eyes, as long as 

 pronotum and scutellum united, joint 2 longest, thickened to- 

 ward apex, 3 and 4 much thinner, united about half the length 

 of 2 ; eyes very large, reniform, almost covering sides of head, 

 male, relatively smaller, female ; pronotum slightly more than 

 twice as broad as long, sides flattened, rather broadly reflexed, 

 disk with a preapical transverse narrow ridge and a rather 

 sharp percurrent median carina ; scutellum as broad as long, 

 somewhat elevated above the corium ; elytra entire, costal mar- 

 gin evenly rounded and reflexed, venation as in fig. 8 ; mem- 

 brane with one cell ; abdomen of females as in fig. 9. Four 

 species are known from the United States, two in our territory. 



KEY TO EASTERN' SPECIES OF CORTICORIS.
