latter before the middle. The basai part of the metanotum is smooth on either side of the 

 areae, the rest irregularly obliquely striated; the apex is much more strongly striated and 

 more or less reticulated ; the spines are small, but distinct. Abdomen smooth, the 2nd segment, 

 and the basai half of the 2°à more finely so; gastracoeli whitish to pale reddish. Probably 

 a variable species as regards size and colouration. The 2 black lines on the i st abdominal 

 segment may become united ; the black spot in the centre of the apical slope of the metanotum 

 varies in size and shape. 



Ophioninae. 



Porizionini? 

 Anunda gen. nov. 



Stigma large, widened before the middle, longish triangular, the radius issuing from 

 shortly behind its middle. Radial cellule large, wide. The radius issues from the apex of the 

 basai third of the stigma; it has 2 abscissae, the basai shorter and more rounded than the 

 apical. Areolet large, 5-angled. Transverse médian nervure interstitial. Transverse médian 

 nervure in hind wings broken in the middle. Eyes large, converging below, reaching to the 

 base of the mandibles. Clypeus not separated from the face, its apex broadly rounded. 

 Mandibles unequally bidentate. Occiput and cheeks margined. Parapsidal furrows distinct. 

 Metanotum regularly areolated ; the areola large, longer than wide, 6-angled, the apex 

 transverse; there is a small petiolar area; there are 3 outer areae, the central the larger; the 

 metanotal spiracles round. The ist abdominal segment slender, of equal width; the spiracles 

 prominent, placed shortly beyond the apex of the basai third; it is longer than the 2nd 

 segment, which is roundly curved above and narrowed at the base, where it is one third of 

 the width of the apex; it is twice longer than wide at the apex; the 3 rd is of more equal 

 width; it is about one quarter longer than wide, the 4 th a little longer than wide, the 5 th almost 

 square, the 6 th shorter than it. Calcaria and claws small, the latter simple. The transverse 

 basai nervure is not thickened at the apex. There is a curved furrow bordering the meso- 

 sternum. Middle tibiae with 2 spurs. The abdomen is not compressed; it is broadly rounded 

 above. The occiput is roundly incised. The cubitus does not extend much beyond the areolet. 



I am unable to classify this genus to my satisfaction. It certainly can only be referred 

 to the Ophioninae, but to what tribe of that group, I am unable to say. On the whole it 

 cornes nearest to the Porizionini, but is not typical of that Tribe. When the $ has been 

 discovered probably a new Tribe will hâve to be formed for it. The form of the abdomen — 

 it not being compressed — is hardly characteristic of the Ophioninae, but it certainly cannot 

 be referred to the Pimplinae or Tryphoninae.
