notum somewhat strongly , the lateral more weakly punctured ; 

 the former is distinctly separated. Scutellum more closely and 

 strongly punctured ; its apex with a testaceous projecting keel. 

 Base of metanotum obliquely depressed ; its centre with a stout 

 keel which joins the areola ; the latter is about 3 times longer 

 than wide ; obliquely bluntly narrowed at the base , the apex 

 transverse ; it is bounded by a large area slightly narrowed at 

 the base , which is bounded at the base , not by a keel , but by 

 a raised part ; the sides are keeled throughout ; this keel forming, 

 with the keel of the 2 nd area, a large triangulär one ; there are 



2 keels in the middle of the apical slope , the sides of which 

 bear a few Striae. Propleurae smooth ; the mesopleurae weakly, 

 the metapleurae more strongly punctured ; the mesopleural furrow 

 weakly crenulated.

Black, the head, thorax and palpi red, the 4 anterior legs 

 of a paler red, the middle tibiae and tarsi fuscous, the hind 

 coxae fuscous below, reddish at the base ; wings uniformly fus- 

 ' cous, tinged with violaceous, the nervures and stigma fuscous ; 

 the 2 nd cubital cellule narrowed in front, it being there about 

 one fourth of the length of the posterior part ; the 2 nd trans- 

 verse cubital nervure is bullated at its junction with the cubitus ; 

 it emits from its middle a long nervure, which extends a little 

 beyond the middle of the radius. Head, pro- and mesothorax 

 smooth. Metanotum smooth ; in its centre is a stout keel, which 

 bifurcates in the middle, the 2 keels forming an elongated area 

 acutely narrowed above, transverse at the apex, and bearing 



3 irregulär longitudinal striae ; the sides of the metanotum are 

 keeled ; below the keel is a narrow, but distinct striated band. 

 The l st abdominal segment from behind the middle, and the 

 2 nd , 3 rd , 4 th and 5 th abdominal, segments are closely, somewhat 

 strongly longitudinally striated ; the l st is depressed in the middle 

 and is a little longer than the 2 nd and 3 rd segments united. 

 Malar space fully one half the length of the eyes. Palpi fus- 

 cous, darker at the base. 



Length 11 mm; terebra 7 mm. $. 



Kuching, Borneo. January (John Hewitt, B. A.). 



The malar space is langer than it is in typical Microdus, 

 the species forming a distinct approach in the form of the head 

 to Agathis; in its other characters it agrees with Microdus. The 

 mesosternal furrow is smooth ; as are also the parapsidal furrows, 

 Calcaria short, the hinder as long as the 2 Ild tarsal Joint. Scu- 

 tellum smooth, rounded, its apex not keeled.
