107. Pselliophora tripudians sp. nov. 



Evidently allied to P. prxfica, but distinguished by the bright 

 rufous of head, thorax, and tibiae. This very strikingly colored

 Java, but is different from these and from any other in coloration. 



Female. Length of body, 18 millimeters ; of wing, 19. Head, 

 with neck and rostrum, entirely bright rufous, with reddish or 

 yellowish hairs and some scattered, long black hairs on occiput 

 only; palpi rufous, with only the extreme tip of last joint deep
