P. CAMERON. HYMENOPTERA. 245 



Lissagathis gen. nov. 



Metanotura entirely without keels, its spiracles longish oval, about four times longer 

 than wide. Scutellum neither keeled laterally nor at the apex. Parapsidal furrows absent, but 

 the mesonotum is raised in the centre at the base. Head broad in front below; malar space 

 as long as the eyes ; front without keels; temples obliquely roundly narrowed, the occiput 

 transverse. Pleurae without a furrow. Abdomen sessile, the i st segment about one half longer 

 than it is wide at the apex, its centre bordered by stout keels which diverge slightly at the 

 apex; the 2^d and yà segments with a smooth, curved furrow near the middle. Radial cellule 

 narrow, not reaching to the apex; the areolet 4-angled; the ist cubital cellule not separated 

 from the discoidal; the 2nd transverse cubital nervure without a stump; anal nervure inter- 

 stitial below; thé transverse médian nervure interstitial; the radius arises from shortly behind 

 the middle. Legs stout, the claws small, simple; the long spur of the hind tibiae one third of 

 the length of the metatarsus. Thorax about 4 times longer than wide. Body smooth and 

 shining. The ovipositor is longer than the abdomen. 



In the arrangement of Szépligeti (Gen. Ins., Braconidae, 116.) this genus would run 

 near to Agathis, from which it differs in the shorter malar space, in the absence of parapsidal 

 furrows and of keels on the metanotum. It, in some respects, cornes close to Aïrophilus, Szép. 

 but that has parapsidal furrows, the metanotal spiracles large, elliptical, the areolet sessile, 

 trapézoïdal, and the face is described as broad and short. 



1. Lissagathis bicarinata sp. n. 



Bivak Island, January; Alkmaar, February. 



Ferruginous, the flagellum of antennae, the apical half of the ist abdominal segment 

 and ail the others, except the basai 3 for the greater part below, black; the basai segment 

 broadly black on the central keel and the outer edge of the 2 nd and 3 r( i white ; legs coloured 

 like the body, the hind tibiae from near the base and their tarsi infuscated ; wings dark 

 fuscous violaceous, the stigma and nervures black. Apex of metanotum with 2 stout keels 

 in the centre ; the basai segment of the abdomen with a stout keel on either side of the 

 middle; the 2 slightly diverging towards the apex. Ç. cf. 



Length 9 mm.; terebra 7 mm. 



The c? does not differ in colouration from the Q. The malar space may be more or 

 less pale yellow. 



Smooth and shining, sparsely covered with short white pubescence. Metanotum without 

 keels; down the centre is a fiât, slightly raised broad keel, with margined sides, which 

 becomes broader and more distinct towards the apex. Abdominal ist segment about one half 

 longer than it is wide at the base, the central part bordered by distinct keels, which diverge 

 a little towards the apex. Malar space as long as the eyes. The ist abdominal segment is 

 longer than the following 2 united.

 Lorentz River, September. 

 Rufo-testaceous, the flagellum of antennae, the base and apex of hind tibiae narrowly
