THE JUMPING PLANT-UCE OR PSYLLID^ OF THE NEW WORLD. 99 



vertex black to reddish with yellowish border; genal cones whitish, 

 sometimes brown at tip; antennae black; prsescutum darker on 

 anterior third; scutum with four brown stripes; legs light colored. 



Head deflexed, broader than thorax, surface smooth, slightly 

 pubescent; vertex broadly and shallowly impressed on each side 

 of median line, front margin rather sharply defined, slightly emar- 

 ginate over anterior ocellus. Genal cones longer than vertex, very 

 slender, acuminate, acute at apex, vertical or even retrose, very 

 sparsely pubescent. Antennae slender. 



Thorax arched, narrow, slightly punctate, sparsely and briefly 

 pubescent. Pronotum short; prsescutum about as long as broad, 

 rounded narrowly cephalad. Wings rather long, hyaline, from two 

 and a half to three times as long as broad, acute to subacute apically. 



Genitalia. — Male. — Genital segment small; forceps spatulate, broad- 

 est at apex, a little shorter than anal valve; latter long, broader at 

 base than at tip, rather densely pubescent. Female. — Genital 

 segment half as long as rest of abdomen, tapering evenly to a very 

 acute point; dorsal valve longer than ventral. 



Described from one male from Algonquin, Illinois (Dr. Nason), 

 the type, and two females from Ames, Iowa (C. W. Mally), May, 1895; 

 one female from Washington, District of Columbia (Schwarz), 

 October, 1883; one female "dipped from surface of ocean 94 miles 

 from Nova Scotia, July 3, 1887." The latter bears the manuscript 

 name of Trioza prohoscidia Riley. Miss Patch's N. ottawanensis, two 

 paratypes of which I have examined and found to belong to this same 

 species, are from Ottawa and Aylmer, Ontario, Canada (W. Metcalfe), 

 May, 1903 and 1905, one of them having been collected on "pine." 



Type.— Cat. No. 18090, U. S. Nat. Mus. 



NEOTRIOZELLA SCDLPTOCONUS, new species. 



k Length of body 1.8 mm.; length of forewing 2.6. General color 

 reddish to reddish brown; pronotum and hind margin of vertex 

 whitish; vertex dark red with light margins; antennae and genal 

 cones black; legs light brown. 

 Head not, or slightly, broader than thorax, deflexed; vertex as in 

 immaculata, slightly pubescent; genal cones a little longer than 

 vertex, thicker than in congenors, closely approximate, vertical, 

 subacute at tip, with rather coarse transverse striae, scarcely pubes- 

 cent, tipped with orange. Antennae about twice as long as width 

 of head, III a little thicker than succeeding segments. 



Thorax somewhat arched, narrow, punctate. Legs slender, rather 

 long. Wings hyaline, a little more than twice as long as broad, acute 

 at apex; venation similar in type to that of congenors. 



Genitalia. — Male. — Genitalia resemble those of immaculata; anal 

 valve relatively longer and produced more into a posterior lobe; 

 forceps broadest subapically, flattened at apex.
