Areola small, wider than long, 4-anglecl. ^ . 



Length 10 m.m. 



Merauke. 



Parapsidal furrows short, on basal slope only, gradually 

 narrowed towards the apex. The entire thorax is impiinctate, 

 shining. Tooth-bearing area narrowed gradually from the outer 

 to the inner side, the keels closely approximating. First abdo- 

 minal segment longer by about one fourth than it is wide at 

 the apex ; the keels are more distinct than usual and extend 

 beyond the middle ; the 2"*^ is slightly longer than broad ; the 

 S""^ almost square, the others wider than long. Antennae brownish, 

 black above ; the scape yellow below. Scutellar keels not very 

 strong. Head strongly, roundly narrowed behind the eyes. 



In Krieger's table (Z. c.) p. 68, this species would come near 

 X. aiistralis Kr. and X similis Kr., both from Australia. The 

 metanotal arese are as in Ä'. australis as shown in Krieger's 

 fig. 11. 



There is a small d" specimen from Etna Bay (8 m.m.) which 

 may represent another species. Unfortunately the pin goes 

 through the areola. There is on it, an irregular transverse 

 stripe on the mesonotum between the tegulse, the black marks 

 on the abdomen are larger than they are on the type ; the 

 marks on the 3"^ segment are larger than they are on the 

 other segments, and the single mark on the 1*' has the sides 

 rounded ; the large apical mark has the apex transverse.
