HYMENOPTERA FROM SARAWAK. 81 



Mesopleurce closely punctured ; the metapleurg reticulated, 

 smooth at the base. Leg's Mack ; the calcaria and spines pale ; 

 the hair dense, long and white. The second recurrent nervure 

 is narrowed at the top, being there as wide as the space bounded 

 by the first recurrent and the second transverse cubital ner- 

 vures ; the first transverse cubital nervure is straight and 

 oblique ; the second is curved and only slightly oblique. The 

 first abdominal segment is broad at the base ; below it is flat ; its 

 central keel does not project much and the part bordering it is 

 irregularly punctured on either side of it. The last segment 

 above is closely punctured, except for a smooth space in the 

 middle at the apex ; below, the apical half is stoutly keeled along 

 the sides. 



Agrees closely in colouration with M. Herein, which may 

 easily be separated from it by the keels on the front and vertex. 



SCOLIIDiF. 



Scolia (Triscblia) afjlana, sp. nov. 



Long : 12 mm. 6 

 Hab. Sarawak (Shelford). 



This species is not unlike what I take to be S. opalma Sm., 

 which has also been taken in Borneo by Mr. Shelford. The 

 difference between the two may be expressed thus : — 



The frontal area clearly defined bounded by a ridge behind, 

 the hair on the head and thorax black ; the median 

 segment punctured throughout. opalina, Sm. 



The frontal area not clearly defined, not bounded by a 

 ridge behind ; the hair on the head and thorax white ; the 

 median segment not punctured throughout, there being a 

 wide smooth space on the inner side of the lateral lobe. 



aglana, sp. nov. 

 Antennee opaque, bare. Head strongly and closely punc- 

 tured and thickly covered with long white hair ; the middle of 

 the clypeus smooth impunctate ; there is no defined frontal area. 

 Mesonotum closely and rather strongly punctured, less closely 

 in the middle. The scutellum and post-scutellum are similarly 

 punctured. The central region of the median segment is bound- 

 ed by a distinct deep furrow and is punctured, if anything, more 

 strongly than the mesonotum ; the inner half of the outer lobe
