Trioza acutipeunis n. sp. 



(Figs. 128 E; 129 D. ) 



Length of body. 1.7 mm. ; length of forewing, 3.5 mm. ; greatest width of 

 wing, 1.3 mm.; width of vertex between eyes, .44 mm.; with eyes, .66 mm. 

 General color, yellowish brown, scutum with brown stripes. 



Head scarcely deflexed ; with eyes about as broad as thorax ; finely 

 rugoso-punctate. Posterior margin of vertex broadly emarginate ; discal por- 

 tion of frontal plates with a fovea near center, slightly nearer to posterior 

 margin and median suture ; frontal plates not raised plate-like, emarginate 

 anteriorly at median suture. Anterior ocellus at angle of facial cones, slightly 

 visible from above. Facial cones moderately long, stout, quite divergent, 

 rounded apically, subvertical but barely visible from above, very sparsely 

 pubescent. .\ntenn?e inserted on basal portion of cones without and above ; 

 Ijasal segment subglobose, the remaining segments destroyed. 



Thorax slightly arched, ascending from pronotum to middle of dorsulum ; 

 more coarsely rugulose than head. Pronotum very long, not depressed below 

 dorsulum and head ; with the posterior margin arcuate, emarginate at center of 

 receive a small projection of dorsulum ; anterior margin with an acute pro- 

 jection at center smaller than that on dorsulum; with a fovea on each side 

 just above the episternum. Dorsulum ascending in anterior half, the rest 

 horizontal ; scutum descending posteriorly, with five brown stripes somewhat 

 darker than ground color. Wings hyaline, about two and four-fifths times as 

 long as broad, broadest across first marginal cell, acute apically ; with several 

 very light brown and indistinct maculae, one in inner basal cell beside the 

 first furcal, another extending through first marginal cell to second cubital, 

 a third at tip of wing in second marginal cell ; radius longer than second cu- 

 bital ; fourth furcal terminating very near to apex of wing; venation brown, 

 quite distinct. 



Male. — .Abdomen slender, larger basally ; genital segment one-fourth as 

 long as rest of abdomen. 



Claspers attached to tip of genital segment, bilobate, with a projecting 

 lobe extending posteriorly ; anal segment produced dorsally into an arched 

 process ; penis between anal arch and claspers ; claspers and anal arch quite 

 thickly pubescent.
