The' peculiar venation serves at once to distinguish members of 

 this genus. The third vein is united to subcosta by a distinct, 

 obHque crossvein and joins the margin at or near the apex, rarely 

 or never beyond. The fifth and sixth veins are distinct, simple. 

 There are 13 or 14 antennal segments, sessile in the female and with 

 an evident stem in the male. Most peculiar of all, the flagellate 

 segments are ornamented in both sexes' with very highly developed 



Fig. 2 Winnertzia calciequina; a, sixth antennal segment of female 

 showing "horseshoe" circumfili; b, ninth antennal segment of male, opposite 

 aspect from that shown in fig. 4; enlarged (original) 



and peculiar circumfiH. The latter resemble minute horseshoes, 

 nails and all, fastened to opposite sides of the segment. These 

 organs occur nearer the base of the segment in the female than in 

 the male. The palpi are quadri articulate, the claws toothed and 

 the prd villi short or rudimentary. The male genitalia have the 

 terminal clasp segment short, stout, with a distinct apical tooth and 

 the basal clasp segment very broad and stout. The dorsal and 

 ventral plates are also stout. There are a series of distinct thick- 

 enings or chitinous rods (plate 5, figure 4) which give the genitalia 

 of this genus a very characteristic appearance. The ovipositor is 

 long, stout and with bi- or triarticulate lobes usually attached to 

 the dorsal angle. Type Asynapta lugubris Winn. There 

 is a good series of fine females (no males) in the Winnertz collection 

 at the University of Bonn. Our American forms are evidently 

 cogeneric.
