Hab. Kuching, Sarawak. 



Scape of antenna yellow, dark testaceous above, the 

 Hagellum blackish, brownish at the base and apex beneath. Head 

 dark ferruginous, thickly covered with silvery pubescence, the 

 vertex sparsely with fuscous hair ; the lower inner orbits to near 

 the inner part of the incision ; the sides of the clypeus broadly, 

 its apex more narrowly, a line on the outer orbits near the top, 

 another one below and the base of the mandibles broadly above, 

 pale yellow. The front and the vertex to the end of the ocelli 

 are distinctly, regularly, but not very closely, punctured ; the 

 clypeus is sparsely punctured, more especially noticeable on the 

 dark central part. The meso- and metapleurte are black, the 

 metanotum dark rufous; the rest of the thorax rufous, with the 

 following parts yellow : the base of the prothorax all round and 

 broadest on the top of the pleurae, a large mark on either side of 

 the base of the scutellum, a broad band, incised in the middle, on 

 the base of the post-scutellum, two large marks on the apical 

 slope of the median segment, and a longish mark on the meso- 

 pleuree below the tegula?. The pro- and mesothorax with the 

 scutellum are closely and distinctly punctured ; the median 

 segment is almost impunctate ; its central furrow is wide, with

 the costa and stigma blackish ; the nervures pale. The petiole is 

 not quite so long as the second segment: its basal third is narrow- 

 ed; the second segment is not narrowed at the base.is bell-shaped, 

 its length greater than its width at the apex and it is closely and 

 distinctly punctured, more closely and rugosely at the base than 

 at the apex ; the following segments are lined with yellow at the 

 apex. 



Comes near to /. fefruginea, but is smaller, and darker
