on the outer and inner edges. Ab(loniinnl petiole hardly half the length of 

 the hinder coxae, which are longer than usual, as long as the femora, and 

 narrowed towards the apex. Femora with about sixteen small, round, 

 black, closely packed teeth, except at the base where they are more wide- 

 ly separated; the basal is large and sharper than the others; on the upper 

 side of the hind coxae at the apex are two teeth, the upper the larger. 



1420 Spilochalcis. Segoviae sji. nov. 



Yellow, largely tinged with rufous, the abdomen largely blackish 

 (perhaps discolored), flagellum of antennae and ovipositor sheath black; 

 wings hyaline, a distinct cloud at the stigma; femoral teeth small, black, 

 fourteen in number. Female. Length 5-6 mm. San Marcos, Nicaragua. 



Antennal scape slender, reaching above the vertex. Sides of front 

 and vertex shagreened, sparsely, shortly haired; the rest of the head 

 smooth, shining. Mandibular teeth black. Mesonotum and scutellum spar- 

 sely covered with black hair, the middle lobe obscurely striated, the la- 

 teral striated on the inner side at the apex, the outer punctured. Meta- 

 notum reticulated, the basal central area is of equal width throughout 

 and has a strong keel down the centre, the apical is horse-shoe shaped. 

 Abdominal petiole short, about three times longer than broad, about one 

 third the length of the hind coxae, which have a sharp, short tooth on 

 the apex above, followed by two slight tubercles. The antennae are long 

 and slender. 



1424 Spilochalcis Belti sp. nov. 



Pale yellow, the flagelknn of antennae brownish, black on top, femo- 

 ral teeth minute, black, sixteen in number, apex of scutellum rounded, the 

 bordering keel stout, thickened in the middle; abdominal petiole short, 

 about twice longer than broad, about one sixth of the length of the hind 

 coxae, which are distinctly longer than the femora. Metanotuni with a 

 central basal keel which bifurcates round the top of the apical slope, 

 the other keels are indistinct. Middle lobe of mesonotum obscurely trans- 

 versely striated, the scutellum shagreened ; both are covered with short 

 white pubescence. Scape of antennae long compared with the flagellum, 

 projecting considerably above the top of the vertex. Ovipositor largely 

 projecting. Length 4 mm. Chinandega, Nicaragua. 



1422 Spilochalcis Marcosensis sp. nov. 



Yellow, rufous above, the flagellum of antennae fuscous, black 

 above; wings hyaline, the nervures fuscous, a small cloud at the stigmal 

 branch; the head and thorax above thickly covered with short fuscous 

 pubescence; abdominal petiole longish, fully half the length of the hind 

 coxae, slender ;\ femoral teeth small, there are eleven clearly separated 

 teeth and three or four united more or less, at the base. Antennal scape 

 slightly curved, the apex almost reaching to the hind ocelli. Pleural sutu- 

 res marked with black. Mesonotu:n shagreened; the scutellum finely 

 striated, its apex broadly rounded. Metanotum shagreened; on the apical 

 half is an area in the centre which is somewhat obliquely narrowed above,
