more rows of irregular spots, is in midas formed by the cou- 

 fluenceof these spots into wedge-shaped dashes, and is suggestive 

 of the markings of C. dispar var. rutilus. This row of black wedge

DESCRIPTION OF A NEW GENQS AND SPECIES 

 OF OXYUBA (HYMENOPTERA) FROM KUCHING, 

 BORNEO. 



By p. Cameron. 



Laccomerista, gen. nov. 



Antennas thirteen-jointed, placed near the mouth, on a swelling, 

 which is obliquely sloped below them, its edges below each antennae 

 projecting into a stout tooth, longer than wide ; the apex is obhque. 

 Head as long as it is wide at the vertex ; the temples obhquely nar- 

 rowed, wide, the occiput transverse, stoutly margined, as are also the 

 cheeks. Eyes oval, the malar space half their length; a keel runs 

 from their top on the inner side to. the antennae. Ocelh in a curve. 

 Pronotum large, almost twice longer than wide, narrowed towards 

 the base ; the latter is narrowed, clearly separated, and bears two 

 broad rounded keels, separated by a distinct furrow. Parapsidal 

 furrows distinct, complete. Scutellum large, almost flat, separated 

 from the mesonotum by a narrow furrow. Metanotum short, its apex 

 with a rather steep, oblique slope. Abdomen oval, shorter than the 

 thorax, roundly convex above, flat below : the second segment very 

 large, much larger than all the rest of the abdomen. Wings with a 

 large, wide stigma, rounded behind ; the radial nervure is short, 

 oblique, straight, and issues from the apical fourth of it ; there are 

 two distinct basal cellules, the posterior being shorter than the 

 anterior. Legs stout, the calcaria short, slender. Spurs small, 

 simple. Hind tibis thickened towards the apex, which above ends 

 in a short spine. Metatarsus stouter than the following two joints 

 united. Tegulae large, longish. Antennal flagellum stout, longer 

 than the foHowing three joints united, and reaching above the top of 

 the head ; the pedicle as wide as long ; the following joint clearly 

 longer than the next ; all the joints elongated. The form of the 

 mandibles I am unable to make out, and I have not a spare example 

 for dissection ; neither can I make out the exact number of abdominal 

 segments, of which I can only detect five. There are two spurs on 

 the four posterior tibiae. The scutellum is almost square, and is 

 bounded laterally by a furrow. 



On the whole this new genus fits best into the Bethylida, but 

 it has not the one-jointed trochanters of that group, so far as I 

 can make out. The neuration is more, in some respects, that of 

 the Scelionidffi, e. g. Calliscelis ; certainly the form of the radial 

 nervure differs from what it is in the Bethylidse, in which it is 

 more or less roundly curved. The form of the head is different
