Ischnogaster Guér. 



1. Ischnogaster canaliculatus sp. n. 

 Bivak Island, January. 



Rufous, the antennae, head except the clypeus, the greater part of the node of pétiole, 

 the 2 nd segment except irregularly at the base and sides, the 3 ld , 4* and 5 th segments and 

 the hind legs except the coxae, apex of femora narrowly and of the tibiae more broadly, 

 rufous black; the wings iridescent, hyaline, tinged with fuscous, the apex of the costal cellule 

 and the radial smoky, the nervures black; the i st abscissa of the radius not quite half the 

 length of the 2^ A , which is about one quarter shorter than the 3^ and 4 Ul united, the 3 rd 

 and 4 th are almost equal in length, the i st récurrent nervure is received near the base, than 

 is the 2 nd from the apex of the cellule ; the 2nd récurrent nervure is roundly curved back- 

 wards to shortly below the middle, the lower part less strongly bent backwards, there being 

 a small projection on the outer part of the junction. Smooth and shining, almost bare; the 

 metanotum with a distinct furrow. Abdominal pétiole fully twice the length of the thorax. Ç>. 



Length 15 mm. 



The clypeus becomes gradually narrowed to a sharp point at the apex; there is a 

 narrow furrow between the antennae; there is a narrow curved oblique furrow below the 

 middle on the mesopleurae. The hind tibiae are thickly covered with longish black hair 

 behind. The face and clypeus are thickly covered with pale fulvous pubescence. There is an 

 oval tubercle on the apex of the propleurae in the middle. The amount of rufous colour on 

 the sides and base of mesonotum varies. The base of the antennal scape varies, as does also 

 the quantity of reddish colour on the hind legs.

1. Abispa miaculicollis, sp. n. 

 Bivak Island, January. 



Black, the antennae, clypeus, labrum, mandibles except the apex and the apical half 

 on the inner side, antennal keel, the inner orbits narrowly, the eye incision, the outer orbits, 

 the line broad above, becoming gradually narrowed below, the black central part of the 

 front and vertex being of equal width, a broad mark on the base of the pronotum, oblique 

 at the apex and extending from the base to shortly beyond the middle, the sides of the 

 metathorax broadly and lines on the apices of abdominal segments 1 — 5, the 4 th and 5 th almost 

 entirely, the apical entirely and the legs except the coxae, trochanters and base of femora 

 narrowly and irregularly, rufo-ferruginous. Wings ferruginous, the apex from the i s t transverse 

 cubital nervure light fuscous violaceous. Q. 



Length 25 mm. 



Head and thorax covered with short pale pile. Clypeus about one half longer than 

 wide, sparsely punctured, except on the obliquely sloped sides, broadly rounded above, the 

 apex with a broad shallow rounded incision. Front strongly, but not very closely punctured,
