THE JUMPING PLANT-LICE OR PSYLLIP^ OP THE NEW WOBLD. 67 



Thorax somewhat arched, broader than head including eyes, 

 rather coarsely punctate. Prsescutum longer than in preceding 

 species, relatively narrower, rounded, cephalad. Wings rather large, 

 hyaline about two and a half times as long as broad, rounded apically 

 or very broadly angulate; marginal cells subequal; one specimen 

 presents the anomaly of the furcation distally of the radial sector 

 of both primary wings. 



Genitalia. — Female. — Genital segment long, slender, about as long 

 as rest of abdomen ; dorsal valve sUghtly longer than ventral, equally 

 acute but less slender; pubescence sparse and. short. 



Described from four females from Oaxaca, Mexico (Crawford), 

 August 10, 1910. 



Type specimen in author's collection. 



KUWAYAMA DORSALIS, new species. 



Fig. 41.5. 



Length of body 1.8 mm.; length of forewing 2.9; width of head 

 0.70. General color chocolate brown on dorsal surface of head, 

 thorax, and abdomen; lighter on pleiiral and ventral regions and on 

 legs; dorsal surface smooth. 



Head almost as broad as thorax, not deflexed; vertex about twice 

 as broad as long, with a foveal depression near posterior margin on 

 each side of median Une, anterior and lateral margins sharply defined, 

 somewhat elevated. Gense subspherically swollen beneath antennal 

 bases. Clypeus large. (Flagellum of antennsB broken off.) 



Thorax only a Uttle arched; pronotum very short; prsescutum 

 ascending, long. Forewings hyaline, acute at apex, more than two 

 and a haK times as long as broad; marginal cells small; radial sector 

 short. 



Genitalia. — Male. — Genitalia small; forceps slender, almost as long 

 as anal valve, acute at apex; viewed from behind, with apical half 

 much narrower, flattened laterally, basal portion thick with a small 

 inner process. Anal valve with a large posterior lobe, reaching nearly 

 to base of forceps. 



Described from one male from Tucson, Arizona (H, G. Hubbard), 

 December. 



Type.— Cut. No. 18080, U. S. Nat. Mus. 



In some respects this species seems to be closely related to members 



of Paratrioza. 



LEURONOTA, ne^w genus. 



Head not as broad as thorax, scarcely deflexed; notum almost flat, 

 scarcely arched; genal processes conical, divergent. Antennae more 

 than twice as long as width of head, slender. Pronotum long, flat, 

 not descending cephalad, produced in the center of the anterior 

 margin into an acute epiphysis, on same level with praescutum and
