25. Body mostly black,' at most antennae, a narrow ocular band. 



oral area narrowly, sides of pronotum, tegulae, and most of 



legs, yellow 26. 



Body less black and more yellow than the above, especially 

 head and thorax, and often also abdomen, more yellow 28. 



26. Length of Ijody in both sexes nbout 2 mm., 12 or 13 setae on sub- 



marginal vein, head almost or quite two-thivds as long as 



wide wiltzae (p. 83i. 



Length usually distinctly more than 2 mm., always so in fe- 

 males, 16 setae on submnrginal vein, head one-half to three- 

 fifths as long as broad 27. 



27. Yellow of pronotum confined to anterior lateral corners, not 



reaching to hind edge of this segment, legs yellow except 

 coxae, which are black, head from above twice as wide as 



long, face flat or feebly convex florida (p. 86). 



Yellow of pronotum attenuated posteriorly but reaching hind 

 edge of the segment laterad, coxae black, also disks of femora 

 and tibiae especially of middle and hind legs, black, head 

 about three-fifths as long as wide marylandica (p. 85i. 



28. Vertex mostly or entirely black, occiput black, the black of 



these two areas confluent ; more or less of middle third of 

 pronotum, all or most of prescutum and scutel, propodeum 



entirely, and dorsum of abdomen broadly, black 29. 



U.sually only ocellar area of vertex, and occiput narrowly, 

 black, the black of these areas usually widely separated 

 or connected only by a narrow band ; thorax with a more or 

 less complete and irregular mid-dorsal longitudinal black 

 band, often not extending to pronotum; anterior surface 

 and groove of propodeum, and often only an irregular band 

 on dorsum of abdomen, black, latter band frequently pro- 

 duced sideways on the segments 31. 



29. Length 2.2 to 2.7 mm., abdomen of females mostly ochreous- 



yellow on the sides, 12 to 13 setae on submarginal vein. 



quinqueseptae (p. 78). 

 Length 3 to 3.3 mm., sides of female abdomen not always 



mostly ochreous-yellow, 12 to 16 setae on submarpinal vein 30. 



30. Length 3 mm., 12 to 14 setae on submarginal vein, sides of fe- 



male abdomen mostly dark like dorsum, only venter or lower 



portions of sides lighter in color foliatae (p. 79). 



Length 3.1 to 3.3 mm., 12 to 17, usually 14 to 17, setae on sub- 

 marginal vein, sides of female abdomen mostly oclireous- 

 yellow foliatae var. arizonica (p. 82). 



^ The key does not provide for separating certain mostly black males of the qiterci-lanae 

 var. dorsalis (Fitch) type. All such will lead to porida Giraiilt, marylandica Girault. or 

 wiltzae, new species that are black in both sexes. Besides these species, foliatae Asliraoad, 

 foliatae arizonica, new variety, and quinqueseptae, new species, have this black form of 

 male in addition to the lighter form. The black, or variety dorsalis type, of male of all 

 these species is very similar and can not be positively distingnished to date. See discns- 

 sJon under qnrrci-lan-ae var. dorsalis (Fitch), page 74.
