HYMENOPTERA OF SARAWAK. 99 



the apical larger than the basal, two. Mesonotum coarsely, 

 rugosely punctured and irregularly reticulated. Scutellum 

 with 4 irregular, curved transverse keels; the depression at its 

 apex and at the base of the metanotum stoutly, closely striated. 

 Median segment irregularly, strongly reticulated. Pleurae, 

 except at the base of the pro-, closely irregularly reticulated. 

 Antennae 14-jointed; the scape not quite twice the length of 

 the 2nd ; the 2 together are slightly longer than the 3rd, which 

 is distinctly shorter than the 4th. Temples wide. Hinder ocelli 

 separated from each other by the same distance they are from 

 eyes. Base of middle lobe of mesonotum slightly roundly 

 incised in the middle. First recurrent nervure interstitial with 

 the cubital, dilated at its junction with it ; the 2nd received 

 shortly beyond the middle of the cellule ; the 3rd abscissa of 

 the radins is as long as the other two united. Claws with 4 

 teeth, the 2 central being longer and sharper than the others. 

 The 5 is similarly coloured, has the vertex obliquely raised 

 from the front and has the sides bounded by a longitudinal keel. 



Gasteruption rufomaculatum, sp. nov, 



Black, the mesopleurae and mesosternum rufous ; as are also 

 the front legs and the underside of the middle coxae, there is a 

 broad white band near the base of the hind tibiae ; wings hya- 

 line, the stigma fuscous, the nervures darker. $ . 



Length 13 ; terebra 6 mm. 



Hab. Kucbing. 



Front and vertex shining, smooth, almost bare ; the face 

 and clypeus and outer orbits thickly covered with silvery 

 pubescence ; the hinder occelli are separated from each other by 

 a slightly greater distance than they are from the eyes, The 

 clypeus above, in the middle, is separated from the face by a 

 distinct curved furrow. Mandibles and trophi dark rufous. 

 Middle lobe of mesonotum closely and strongly transversely 

 striated ; the sides of the lateral lobes are more finely striated ; 

 the middle at the apex much more widely and more strongly 

 longitudinally striated. Scutellum obscurely transversely stri- 

 ated. Median segment rather strongly transversely striated,
