HYMENOPTERA OF SARAWAK, 135 



very strongly transversely striated, the striae on the metapleurae 

 are stronger and commence shortly behind the middle. Areolet 

 square, hardly narrowed behind ; the recurrent nervure received 

 in the middle. 



This species may be known by the weak striation on the 

 pleurae and metanotum, by the middle lobe of the metanotum 

 being smooth, not reticulated, and by the brownish splashes on 

 the thorax. 



Lactolus reticulatus, sp. nov. 



Black, labrum, palpi, a broadband on the middle of the an- 

 tennae, post-scutellum, the apical 3 segments of the abdomen 

 above, base of first, a curved mark on the apical slope of the 

 metanotum, and the hind tarsi, except narrowly at the base, 

 white ; 4 front legs and hind coxae, rufous, the 4 front tarsi fus- 

 cous ; wings hyaline, the stigma and nervures black. 9 • 



Length 10 ; terebra 4 mm. 

 Hab. Kuching. May. 



The centre and the lower part of the front with some irregu- 

 lar keels ; the face irregularly rugose ; the clypeus smooth. Pro- 

 aud mesonotum smooth and shining, the centre of the latter at the 

 apex with a band of twisted striae ; the base of metanotum entire- 

 ly smooth and shining ; the rest closely transversely striated. 

 Apex of pronotum punctured closely above, the rest, except 

 below, striated. Mesonotum closely, irregularly longitudinally 

 striated, except in the middle ; the metapleuraae closely rugosely 

 striated. Areolet longer than broad, the nervures not con- 

 verging below. 



This species, in colouration, agrees closely with L. basima- 

 cula, but that is a larger and stouter speciej, its areolet is square, 

 not broader than long and it is narrowed behind, its scutellum 

 and hind femora and tibiae are brownish and there is a large 

 white mark behind the hind wings. 



Lactolus basimacula, sp. nov.
