20 PBOCEEDINGS OF THE NATIONAL MUSEUM vol.71 



ample, marginal and submarginal veins nearly equal, submarginal 

 with two prominent bristles dorsally, discal cilia nearly uniform from 

 base of marginal vein to apex of wings and not quite as close together 

 as in forrnosa Gahan; longest marginal cilia about one-third as long 

 as the width of wing; middle tarsi 4-jointed, its basitarsus only a 

 little longer than the apical joint; hind basitarsus about twice as long 

 as the apical joint; abdomen subequal to the thorax or a little longer, 

 the ovipositor barely visible at apex. Color nearly uniformly pale 

 yellow throughout, the vertex tinged with orange yellow; ocelli pale 

 red; eyes black; antennae and legs pale; wings perfectly hyaline, 

 venation pale. 



Male. — Similar to the female but differing somewhat^in color and 

 antcnnal characters. Antenna 8-jointed; pedicel not longer than 

 broad; flagellar joints subequal and each nearly three times as long 

 as thick. Head above orange yellow with a dusky transverse band on 

 occiput, the face and cheeks pale yellow; pronotum, anterior margin 

 of praescutum and axillae dark brownish; rest of thorax orange 

 yellowish; abdomen blackish brown with a narrow transverse band at 

 base and the extreme apex slightly paler. The axillae appear to be 

 somewhat more distinctly granular than in the female and the meso- 

 seutum and scutellum apparently have some rather large reticulations. 



Type locality. — Miami Beach, Florida. 



Type.—Csit. No. 29445, U.S.N. M. 



Host. — Trialeurodes jloridensis Quaint nnce . 



Ten females and nine males mounted in balsam on five slides. 

 Reared from the above-mentioned host on avocado, May 12, 1924 

 by G. F. Moznette. 



ENCARSIA BASICINCTA, new species 



Belongs to the group having all tarsi distinctly 5-jointed, and 

 resembles pergandiella Howard but may be distinguished from that 

 species by the shorter first funicle joint, as well as by the much 

 paler general color and the presence of a conspicuous blackish or 

 fuscous band at the base of the abdomen. 



Female. — Length 0.57 mm. Antennae not quite as long as body, 

 very weakly clavate; pedicel ovoid, about one and one-half times as 

 long as thick; first funicle joint shorter and narrower than the pedi- 

 cel, about one and one-half times as long as thick; second distinctly 

 longer than the first, about equal in length to the pedicel; third to 

 sixth subequal in length and each approximately one and one-half 

 times the second; the last two joints are somewhat more closely 

 joined together than the preceding but are no thicker than the fourth 

 joint and only shghtly thicker than the first; flagellar joints with 

 sparse inconspicuous hairs; mandibles tridentate; vertex granularly 

 rugulose; mesoscutum and scutellum also granular, the paired setae 

 all pale and very inconspicuous; forewings rather small (0.47 mm.
