CAMERON—HYMENOPTERA. (1 
Palpi pale yellow. The apex of the scape and the pedicle are testaceous ; the third joint 
is nearly as long as the following two united. Ocelli in a triangle; the hinder close to the 
eyes. Pro- and mesothorax smooth; the metanotal area clearly defined, the lateral 
furrows distinct, curved, irregularly crenulated; the central furrow is wider, becomes 
widened towards the apex, and is closely, stoutly, transversely striated; the furrow on 
the apical slope is narrower, deep, with obliquely sloped sides; the basal transverse 
furrow is crenulated. The pubescence on the head and thorax is dense and silvery. 
The wings are short and do not reach to the apex of the second abdominal segment ; 
the basal abscissa of the radius is straight, oblique, the apical slightly roundly curved 
towards the costa, reaching to the apex of the wing. The second and third segments of 
the abdomen are almost equal in length; the last is compressed, laterally forming a 
triangle, ending ina sharp point, acute above but not keeled. The abdomen is distinctly 
more than twice longer than the thorax. The undersides of the trochanters are pale. 
The thorax is as long as it is wide at the apex; the face is furrowed narrowly on the 
sides. 
It is worthy of remark that Saussure (Reise d. Novara, Hymen. p. 84) describes a 
species closely related to that here described and with a long abdominal petiole (but only 
of the length of the thorax’, the locality of which is given as ‘‘ Mauritius ? vel Brasilia ? ” 
The petiole in the present species is longer than usual; its apex, seen from the sides, 
forms a longish triangle ; it is not much dilated laterally. 
18. Notogonia seychellensis, sp. nov. 
Black, the hind femora red, the apex of the hind tibie narrowly and the basal 
four joints of the hind tarsi of a paler red; wings hyaline tinged with yellow at the 
base, the rest pale fuscous violaceous, the nervures and stigma black. 2 & 6. 
Length 12 mm. 
Localities. Seychelles, Mahé (H. P. Thomasset). 
Covered with silvery pile and more sparsely with short white hair. Eyes large, 
distinctly converging above, at the top separated by two-thirds of the length of the 
third antennal joint. Occiput transverse; the temples almost obsolete. Pro- and 
mesothorax shining, smooth. Metanotum opaque, bare; the base with a stout keel 
down the centre of the basal three-fourths ; the apical half is finely, obscurely, 
obliquely striated. The apical slope is irregularly, sparsely obliquely striated ; the 
rest more closely, finely, transversely striated. Metapleuree opaque, alutaceous. Apex 
of abdominal segments with a band of white pile. Pygidium rough, as if longitudinally 
striated, sparsely covered with black hair; in fresh specimens probably covered with 
white or silvery pile; it becomes gradually narrowed towards the apex, which is bluntly 
rounded ; it is clearly longer than it is wide at the base. Legs stout; on the outer 
side of the tibize, on the apical half, are at least three stout spines (probably more in 
fresh examples) ; on the apex are three long, stout spines; the tarsi are stout ; the apices 
of all the joints and the apical half of the metatarsus bear stout, longish spines; the 
third joint becomes slightly gradually widened towards the apex, which is transverse ; 
the fourth becomes gradually distinctly widened towards the apex, which has a wide
