Braconidae. 



The Braconidae are fairly represented, the most important genus being Camplonenriis, 

 Szép. which has already been reported from New Guinea by its Author and which no doubt 

 has some species described under Bracon by Mr. F. Smith. I regret that I hâve not been 

 able to identify any of Mr. Smith's- species ; his descriptions only refer to colouration; and 

 his Bracon probably includes Bracon, sensu str., Iphiaulax , Camplonenriis and Megalomma. 



As regards the geographical relationship of the species, Chaolta is a Hindo-Malay 

 genus; Zombrus is also found in Hindo-Malaya but extends beyond India, into, e. g: Africa; 

 Hecabolus is a small genus of wide range, as is also Rhogas. The Agathinae are widely spread 

 over the globe, and more particularly over the warmer régions. Cenocoelius probably represents 

 an old group, formerly much more numerous in species; it is more numerously represented 

 in the Neotropical Zoological Région than any where else; in the old world it is confined, 

 so far as is known, to Malaya and Europe.

1. Chaolta pallidlceps sp. n. 



Regen Island, December. 



Rufo-testaceous, the abdomen darker coloured than the thorax, the head pallid yellow, 

 the antennae and apex of mandibles black; wings fuscous, tinged with violaceous, the basai 

 half of the stigma pallid ochraceous, the 3^ abscissa of radius as long as the basai 2 united; 

 the head and thorax smooth and shining, a furrow down the centre of the metanotum ; it 

 becomes gradually widened towards the apex; the narrowed basai half finely, closely longi- 

 tudinally striated, the apical deeper and more strongly irregularly striated and with a 

 longitudinal keel near the middle. Head smooth, the facial plate semicircular, raised in the 

 centre at the base; the face sparsely covered with long pale hair; the front shallowly depressed, 

 a wide, clearly defined furrow down its middle. Temples nearly as long as the eyes above, 

 broadly rounded behind. Central part of i st abdominal segment closely, rather strongly 

 striated and with a longish, more strongly striated area in the centre of the basai half; the 

 latéral border smooth, faintly aciculated on the inner side at the apex, where it is as wide 

 as the centre; the extrême base is depressed, smooth and with a small smooth, triangular 

 area on the sides at the apex, projecting into the latéral dépression; the 2 nd , yd and 4 th 

 segments are closely striated ; there is an area on the basai half of the 2 nd segment formed 

 by 2 stout keels, curved and thickened at the base, converging towards the apex; there are 

 basai latéral furrows forming . areae ; that on the 2°d is the larger and is more distinctly 

 triangular, more sharply narrowed towards the apex; the other 2 are more bluntly rounded 

 on the apical outer side and do not become gradually narrowed. There are basai crenulated 

 furrows on the 3 rd and 4* and narrower, shallower apical ones; there is a distinct almost 

 smooth one on the base of the 5* and a weakly crenulated one on its apex. Legs rather 

 thickly covered with long pale hair. 9-
