P. CAMERON. HYMENOBTERA I. 



Agathis Latr. sec. Szép. 



i. Agathis albolineata sp. nov. 

 Manokwari, June. 



Rufo-testaceous; the antennal flagellum, abdomen except at the base and the hind 

 tibiae and tarsi black ; the wings dark fuscous, slightly tinged with violaceous, the nervures 

 and stigma black. Q and çf '. 



Length 8 mm.; terebra 8 — 9 mm. 



Smooth and shilling. Scutellar dépression deep. The y d and following segments hâve 

 their apices narrowly lined with clear white. Malar space and outer orbits tinged with white. 

 The areolet is not much narrowed in front; the stump of a nervure issues from near the top 

 and is as long as the transverse cubital nervure. Mandibles pale testaceous, blackish at the apex. 



ICHNEUMONIDAE. 



Irabatha nov. çen. 



Thorax fully 3 times longer than broad ; the médian segment longer than wide, with 

 one transverse keel and with long stout teeth on the apex. Parapsidal furrows not reaching 

 to the apex of the mesonotum, bounding the apex of the middle lobe which is rounded. 

 Scutellum flat, its sides not keeled. Metapleural keel not reaching to the hind coxae. Temples 

 short, sharply obliquely narrowed. Front depressed, keeled down the centre, areolet minute, 

 narrow, longer than wide. Transverse médian nervure received behind the transverse basai. 

 Disco-cubital nervure almost broken by a stump of a nervure. Transverse médian nervure 

 in hind wings broken shortly below the middle and sharply angled. Pétiole long, its apical 

 half widened; the spiracles are nearer to each other than they are to the apex; the segments 

 are smooth. Legs long and slender; the basai joint of the fore tarsi as long as the tibiae. 



The apex of the clypeus is depressed and has a furrow down the middle; above this 

 are 2 longish, shallow foveae ; on the sides is a stout keel. There are 2 keels at the base of 

 the transverse keel on the metanotum. Spiracles linear. 



This genus cornes near to Buodias, a Malay genus; it has a larger, not punctiform 

 areolet; the transverse médian nervure in hind wings is broken half way between the middle and 

 lower part ; the temples are much shorter, almost obsolète above ; the scutellum is more distinctly 

 convex and is stoutly keeled laterally on the basai half. The head is wider than the thorax. 



1. Irabatha albispma sp. nov. 



Superior part of Jamïïr, August. 



Black, shining, the 5 — 10 joints of the flagellum of the antennae, a mark on eitherside 

 of the vertex, touching the eyes, broad at the eyes, gradually narrowed to a point inwardly. 

 palpi, a conical mark on the apex of the middle lobe of the mesonotum, the narrowed. rounded
