HYMENOPTEKA FROM SARAWAK. Ill 



coarsely as the front; its apex broadly rounded. The scape of 

 the antennae is broadly rufous below; the apical joints are brown- 

 ish beneath. Thorax entirely black covered with a pale pile ; the 

 mesonotum and scutellum more thickly with longer pale pubes- 

 cence . Mesonotum closely rugosely punctured ; the punctuation 

 sparser towards the apex; the two furrows are indistinct at 

 the base, being confounded with the punctuation. Scutellum 

 strongly punctured and with a narrow furrow in the middle ; 

 the post-scutellum is, if anything, more rugosely punctured; 

 its apex is opaque, alutaceous. The median segment is opaque, 

 alutaceous, keeled down the centre and at the sides ; above it is 

 obscurely striated. Propleur-ae smooth, the upper part at the 

 base striated. Mesopleura? closely, rugosely punctured; the 

 basal and apical slopes smooth. Metapleurse strongly punc- 

 tured, except for a large oblique space on the base and apex. 

 Petiole closely and uniformly punctured; the base rufous, 

 smooth. Legs bright rufous ; the hinder tibiae and tarsi in- 

 fuscated. 



This does not appear to me to be the P of Jf.-deatatus, as 

 apart from the difference in colouration, there are structural 

 differences between them not of a sexual nature. The two may 

 be separated thus : — 



The furrow at the base of the scutellum with five stout 

 keels; the metapleura? coarsely punctured and striated 

 throughout. Jf.-dentatus. 



The furrow at the base of the scutellum with eight short 

 keels ; the metapleurae sparsely punctured above, smooth 

 below. varipunciatus. 



Ody nevus cilicius, sp. no v. 



Black, largely marked with yellow; the median segment 

 yellow, except in the middle, a dagger-shaped line on the front, 

 a mark on either side of the ocellar region and two oblique large 

 marks on the mesopleurse, yellow; wings hyaline; the radial 

 cellule and the cubital nervures in front dark smoky 9 .
