Length 18 mm.; terebra 4 mm. 
Hab. Matang, 3600 feet. 
Antenne longer than the body, black; the 3rd joint hardly 
longer than the 4th and twice the length of the 2nd; the scape 
about 3 times longer than wide and thickly pilose. Head and 
thorax smooth and shining. The top of the petiole stoutly, ir- 
regularly and not very closely longitudinally striated ; its sides 
below pale orange yellow; the centre of the 2nd segment is 
stoutly irregularly longitudinally striated; the suturiform arti- 
culation is crenulated in the middle; the apical segments are 
narrowly banded with white on the apex. 
The ventral surface is marked laterally with black spots; 
the abdomen is about twice the length of the thorax; the 2nd 
abscissa of the radius is shorter, but not much, than the 3rd. 
[phiaulax portius, 8p. nov. 
Head and thorax ferruginous, the ocellar region black, the 
metanotum infuscated; the 4 front legs rufous-yellow; the 
wings to the stigma yellowish hyaline, the rest fuscous, the 
base of the stigma yellow; the hinder wings yellowish to the 
middle below, above beyond the middle; the greater part of 
the 2nd abdominal segment coarsely longitudinally striated ; 
the 3rd less strongly and distinctly to near the apex; the plate 
on the 2nd segment large, triangular, its keel slightly shorter 
than it; the part surrounding it depressed. 9. 
Length 9 mm; terebra 7 mm. 
Hab. Kuching. 
Antenne black; the scape triangularly projecting on the 
apex below; the 3rd joint, shortly but distinctly, longer than 
the 4th, front and vertex smooth and shining; the face closely 
rugosely punctured; the clypeus depressed, almost smooth, 
rounded above, transverse below. The petiole behind the basal 
slope is irregularly punctured; near the apex it is much more 
strongly and distinctly punctured : the band is prolonged in the 
middle and does not reach to the apex, which is smooth. The 
second segment is smooth in the middle at the apex ; the suturi- 
form articulation is crenulated; the furrows on the 3rd and 4th 
segments are also crenulated, but not strongly. The recurrent
