134 HYMENOPTERA OF SARAWAK. 



Length 13-14 ; terebra 4 mm. 



Hab. Kuching. 



Face rugosely punctured, almost striated, the clypeus 

 smooth, with only a few scattered punctures ; the stria* on the 

 front irregular. Apex of central lobe of mesonotum irregu- 

 larly rugose ; the scutellar keels and the sides and apex of scu- 

 tellum narrowly yellow. Striation on pleurae and metanotum 

 close and strong ; on the apical slope of the metanotum it is 

 oblique above, transverse below and with the centre smooth. 



This species differs from the others by the pleurae and 

 sternum being yellow, not black. 



Friona varipes, Cam. 



Mr. Shelf ord sends from Singapore a $ of this species 

 which wants the white mark on the mesopleurae ; the line on the 

 metanotum commences in the middle, not at the transverse 

 keel and the apical 2 joints of the hind tarsi are black. The 

 species is probably variable in colouration. The 2 white marks 

 under the antennae may be very small, and the colouration of 

 the legs varies. 



Lactolus plagiatus, sp. nov. 



Black, a band on the antennae, the^ apical 3 segments of the 

 abdomen above and the hind tarsi, except at the base, white ; 

 the 4 front legs pale rufous, their tarsi fuscous, the front coxae 

 for the greater part black, the middle black at the base, the 

 hinder rufous ; the pro- and mesopleurae striated in the middle, 

 the meta- more closely and regularly on the lower half ; the 

 metanotum and the nretapleurae for the greater part brownish. 

 Wings hyaline, the stigma and nervures black. $ .
