Parasitic ITymenoptera from Borneo. 161 



there are two keels on the basal half, bordering the centre. 

 The Avhite ring on the antennae is longer than the basal or 

 apical part. There are five or six small teeth on the 

 underside of the hind femora in the middle ; they are 

 widely separated and the middle ones are larger and sharper 

 than the others. 



Neotrimorus ? luttus, sp. n. 



Lnteous, densely covered with long pale hair ; the antennae, 

 ocelli, and hind tarsi black ; the wings smoky, the basal third 

 yellowish hyaline, stigma black. Face rngosely punctured, 

 tiie rest of the head smooth and shining. Pronotum in front 

 closely rngosely punctured ; lower part of pleurae bordered 

 al)ove by a keel, the centre with some stout irregnlar striae. 

 Mesothoiax smooth, the pleural lower furrow crennlated. 

 Metanotum finely reticnlated; the reticulations round for 

 the most part ; the metapleurse much more coarsely, irre- 

 gularly reticulated. The first and the second abdominal 

 segment to near the apex closely, longitudinally striated^ as is 

 also the base of the third and fourth segments. $ . 



Length 8 ; terebra 4 mm.

In the ' Records of the Albany Museum/ i. p. 1G8, I 

 described two species of Braconidse under the name of 

 Trichiobracon, but gave no generic description ; as I was not 

 sure but that the species might be referred to Acanthobracon, 

 Szep., non Kriech. There seems to be considerable 

 structural differences between the species, and it is probable 

 that they might be split up into two genera. Trimorus, 

 Kriech., is regarded by Szepligeti^ as identical Avith his 

 Acanthobracon, but Kriechbaumer says nothing about the 

 coxae being toothed. Tlie third longitudinal nervure in the 

 hind wings may be broadly rounded, or geniculated as it is 

 in T. ru/us, Cam. I give a generic description of the 

 Bornean species mentioned above : — 



Radial cellule long, lanceolate. Transverse median 

 nervure received before the transverse basal ; the recurrent 

 nervure in the first cubital cellule ; accessory nervure inter- 

 stitial. Hind wings with a third longitudinal nervure 

 issuing from the lower part of the transverse praebrachial 

 nerviire and reaching close to the apex of the M'ing ; there is 

 a large basal cellule. Head cuhital, not margined behind.
