Female about 14 mm.; rather dark reddish-brown or ferruginous, legs bright ferni- 

 ginous; maxillary palpi six-jointed, the last two joints very minute. 



The South American genus Svastra Holmberg has five-jointed maxillary palpi, and 



resembles Peponapis in having the third antennal joint of the male short. The inner 



tooth of the hind claws is shorter than the outer, very much shorter in the female, an 



a{)proach toward the condition found in Cemolobus. The mandibles are not bidentate 



at apex in either sex. Svaslra homhylans Holmberg superficially resembles Martinella 



luteicomls.

T]ipe. — (Xenoglossa) Xenoglossodes albata (Cresson). 

 Maxillary palpi five-jointed, the fifth joint sometimes very small.
