 covered more or less densely with short white hairs; color dark ; wings white, 

 with brown maculiB; dorsum uniform brown to lolack. prosopis, new species, 

 a^. Body and wings without glandular hairs, or if present, very short and inconspicu-

Figs. 59, 239, 284, 449. 



Length of body 1.4 mm.; length of forewmg 1.7; mdth of head 

 0.70. General color whitish to very light brown. Body small, 

 finely pubescent. In all the specimens before me the hairs have 

 collected particles of the fine waxy excrement. 



Head not deflexed, not as broad as thorax, punctate; posterior 

 margin arcuate; vertex discally rather plane, with a small foveal 

 impression on each side of median line, scarcely elevated on post- 

 ocellar regions, rounded downward in front, with anterior ocellus 

 beneath. Antennal insertions large, lateral, in front of e3^es; gensB 

 and subantennal regions somewhat swollen. Eyes small. Antennae 

 not longer than width of head, slender. 



Thorax broad, coarsely punctate, Pronotum flat, with lateral 

 "knob" small; pleurites short; dorsum finely pubescent. Wings 

 small, slightly rhomboidal, coriaceous, white to light brown, deeply 

 wrinkled, granulate; about two and a fourth times as long as broad, 

 somewhat rounded at apex; first margmal cell larger than second; 

 pterostigma long and conspicuous; claval suture prominent; veins 

 set biseriately with conspicuous setae, similar in appearance to those 

 on dorsum and vertex. 



Genitalia. — Male. — Genitalia relatively not very small; forceps 

 large, short, broad, subspatulate; anal valve very long and slender, 

 simple, square at tip. Female. — Genital segment short, broad, acute 

 at apex; valves of equal length; pubescence quite dense.
