Spilochalcis lineatiscutis, sp. n. 



Luteous, the upper side of antennal scape, the whole of flagellum, the 

 head except a moderately broad line on the centre of the inner orbits, a 

 broader one on the lower three-fourths of the outer orbits, the line narrowly 

 projecting upwards on the inner side above, the malar space, mesonotum, 

 the scutellum broadly in the middle from the base to near the apex, the 

 apex of the black spot rounded, the 3rd and 4th abdominal segments above, 

 the others entirely, the hind trochanters on the outer side, an irregular mark, 

 almost twice longer than broad on the lower part of the hind femora close to 

 the basal teeth, the teeth, the hind tibiae and their spurs, black ; wings 

 hyaline, the nervures and stigma black ; a broad fuscous cloud extends 

 from the base of the anterior to the stigma, it becoming gradually wider 

 towards the apex, where it extends slightly beyond the middle, the posterior 

 basal part is slightly smoky not clear hyaline like the apex ; the hind wings 

 smoky to shortly beyond the middle. Abdominal petiole of the length of the 

 rest of the abdomen and fully half the length of the thorax. Hind femora 

 with 16 teeth, the basal twice the length of the next, the apical 3 smaller and 

 closer together. Pro and mesonotum and the scutellum closely strongly, 

 transversely striated ; closely covered with short whitish pubescence. 

 Metanotum coarsely irregulaily reticulated ; the areola twice vvider than 

 long, slightly narrowed towards the apex ; the basal and apical keels slightly 

 rounded. Male. Length, 7 m.m. 



Face roundly raised in the centre, strongly irregularly transversely

 of the abdomen piceous red, the back black in the middle ; the apex of hind 

 femora with en irregular clear yellow spot on the outerside the flagellum of 

 antennae black, brownish, at the base below; the femoral teeth, black, small, 

 about 18 in number ; the femora are black on eitherside of the base of the 

 tibite : wings hyaline, the nervures black. Female. Length, 3 m.m. 



Densely covered with white pubescence, smooth, the upper part of the 

 propleuraa finely, closely obliquely striated ; the upper part of the mesopleurae 

 between the keels (which are flat and smooth) irregularly obliquely, not very 

 strongly striated towards the base. Abdominal petiole as long as the slope 

 of the metanotum and one third of the length of the rest of the abdomen 

 f.nd less than one third of the length of the hind femora. Puncturation of the 

 top of head and thorax spaise and weak. 



Spilochalcis megalospilus, sp. n.
