valid; nevertheless the possibility of some of them being synonymic with some in 

 the flavopalliata group must be held constantly before the mind in dealing with them. 

 This applies especially to those named in this connection. In all of the species of 

 this group, the smoky area of the fore wing has more of a tendency to be a band across 

 the wing at the marginal vein, the proximal portion of the wing clear or nearly, not 

 merely broken as in the flavopalliata group. The discal bristle is absent in all of 

 the species. 



Body lemon yellow excepting pronotum, cephalic half of mesoscutum and a broad 

 smoky band across the abdomen, which is as long as about a third of the abdo- 

 men's length, or slightly less; sometimes a second band indicated distad; 

 fore wings hyaline with the exception of the band across it. Antennal club 

 wholly yellow but sometimes dusky at tip. Abdomen longer than thorax, 

 body long, cylindrical ovate aleyrodis Ashmead. 



The same but basal band of abdomen nearly a half narrower or shorter and a second 

 smoky band across the abdomen is indicated by a distinct spot on each side 

 at distal three-fourths; antennal club much shorter and at distal fourth is 

 dusky. Fore and posterior wings much narrower, narrower than in fMvopal- 

 liata. Very small. Fuscous band of wing not clear. Abdomen subequal to 

 thorax, body ovate - basilica Girault. 



The same but nearly immaculate, the body suffused more or less Avith orange. Fore 

 wings slightly fumated to tip. 

 The whole body slightly suffused with orange or pinkish; antennal club nearly 

 wholly dusky. Fore wings moderately broad, the smoky band distinct but 

 the wing slightly clouded to tip; pedical of antenna long-obconic, about four 

 times longer than broad at tip and nearly half the length of the club; curve 

 formed by inner margins of stigmal and marginal (distad) veins long. 



flava Girault. 

 Only the abdomen suffused with orange or pinkish; antennal club lighter, at tip 

 distinctly capped with dusky; fore wings narrower, the smoky band fainter, the 

 wing still more faintly fumated to tip; pedicel of antenna obconic, broader at 

 tip and shorter, only slightly over twice its longest width; the antennal club 

 much shorter. Curve formed by stigmal vein at inner margin short and une- 

 qual flavella Girault. 



Body orange yellow, excepting pronotum, cephalic half or more of mesoscutum and 

 a broad band across the abdomen which is as long as about half of the abdo- 

 men's length or slightly less, sometimes only slightly more than a third. This 

 band is a dark brown. 



Antennal club wholly yellowish, uniform in color coquilletti Ashmead. 



Antennal club half yellowish (base) and half dusky (tip), two distinct colored por- 

 tions aspidioti Ashmead.

Critical remarks on Signiphora Ashmead: The "anomalous 5-lobed appendage" of 



Ashmead is on the middle tibia, not posterior, and is homologous to the middle 



tibial spur of the encyrtids. The genus, however, belongs to the Mymaridae.
