more than one hall' of width of wing; thorax dark brown, sutures pale; abdo- 

 men brown; legs pale, tip- <>t tibiae ami lasl tarsal joints dark, in fronl tarsi 



the basal joinl longer than apical, in hind tai-i the basal joint two and a half 



times longer than apical joint. Wings hyaline whitish, marked with black 

 (Plate 1, fig. 7), two Bpots in Btigma, three in discal cell, a broad streak from 

 fork "t radial Bector ou1 to tip of wing, and several veins margined with dark; 



the anal region mostly dark, and clouds m Beveral cells near middle of wing. 



Veins Mack, >ti^mal vein pale, stigma almosi annulate behind; discal cell 



slender, outer side a little concave; first posterior cell very narrow, shorter 

 on median vein than the areola postica. 



Length 3 mm. 



PSOCUS INTERRUPTUS, sp. now 



Type.— M. C. Z. 10,807. Florida: Lake Worth (Mrs. A. T. 

 Slosson). 



Dark shining brown; antennae brownish, first joint more red-brown, with 

 very short, fine hair, third joint about as long as one half the width of the wing; 

 thorax with sutures pale; legs pale, tarsi ratjier darker, basal joint of front 

 tarsus barely longer than the apical joint. Wings hyaline, with two large 

 dark spots which together form an interrupted fascia; one of the spots on the 

 stigma, and the other over the first posterior cell and a little inward from it; 

 a smaller spot at end of the anal vein (Plate 2, fig. If)). Stigma about its length 

 from the wing-tip, rounded behind; radial sector forks behind bend of stigma, 

 the pedicel very long; discal cell long, much narrowed below, short petiolate 

 to the radial sector, inner side strongly convex; first posterior cell on median 

 vein shorter than tin 1 second; veins pale brown; end of discal cell and fork of 

 radial sector hyaline. 



Length 3.4 mm. 



Syngonosoma reducta, sp. now 



Type.— M. C. Z. 10,80b. Mexico: Orizaba (I). L. Crawford). 



c? . Similar to S. flagellicorne, the antennae the same except that the hair on 

 third joints is a little shorter. It differs from that species in the reduced 

 extent of yellow on the veins, the fork of radial sector being yellow only at 

 base, and no yellow on the forks of the median vein, and the inner side of discal 

 cell darker; the stigma is hardly darker than rest of wing, and is rounded 

 behind, and longer than in S. flagellicorne; the head is also darker; the areola 

 postica is petiolate as in that species. 



Length 7 mm. 



A female from Orosi, Costa Rica, is much larger (10 mm. long); tbe 

 stigma is more yellowish;- the areola postica not petiolate, but other- 

 wise agrees.
