HYMENOPTERA FROM SARAWAK. 113 



Antennae black, the scape yellowish, the flagellum brownish 

 beneath. Head black; the clypeus, the eye incision, a large mark, 

 narrowed in the centre above, and the outer orbits to near the 

 top, yellow. Front and vertex rugosely punctured, the punc- 

 tures running 1 into reticulations on the sides ; the space between 

 the antennae is yellow and smooth. Clypeus long, pyriform, 

 its width at the base half the length ; the basal part roundly 

 convex and irregularly marked with elongate punctures; the 

 apex transverse. Thorax black, a large mark, obliquely nar- 

 rowed on the hinder part, two short narrow lines on the meso- 

 notum, two irregular marks on the base of the scutellum on the 

 sides, the post-scutellum broadly in the middle and the sides of 

 the median segment, broadly, yellow. Mesonotum strongly and 

 closely punctured ; the punctures large, deeper and closer on 

 the base than on the apex. Scutellum flat, on the same level as 

 the mesonotum ; its apex rounded ; it is not quite so strongly 

 punctured as the mesonotum, especially at the base ; the post- 

 scutellum is more coarsely punctured. The median segment is 

 keeled down the middle ; above in the middle it is stoutly irre- 

 gularly transversely striated; the sides, broadly above, nar- 

 rowly below, are stoutly punctured ; below the middle the 

 sides distinctly project into stout blunt teeth. The upper part 

 of the propleurse is irregularly, stoutly, obliquely striated ; the 

 lower part bears stout, longitudinal keels. Mesopleune coarse- 

 ly reticulated. Metapleuree on the upper half irregularly, 

 closely striated. Legs clear yellow, the tarsi darker ; the femo- 

 ra irregularly lined with black. The second cubital cellule at 

 the top is not quite half the length of the third ; the first recur- 

 rent nervure is received shortly behind the middle ; the second 

 is interstitial. All the abdominal segments have a narrow 

 yellow line before the apex ; that on the second is broader than 

 on the others and is largely dilated backwards at the sides ; 

 on the petiole there is a large semicircular mark behind and 

 united to it; on the base of the second laterally is a large irre- 

 gularly oval mark which is incised at the base on the lower 

 side ; the petiole is coarsely, the second and third segments are 

 finely and closely punctured ; the last segment is smooth ; its 

 apex is narrowly yellow. On the second ventral segment, on the 

 sides, is a large yellow mark, which is rounded on the inner side.
