PIMPLIN^. 

 Delebgea, gen. nov. 



Fore wings without an areolet ; the transverse basal nervure 

 roundly curved ; the transverse median nervure received beyond it. 

 Stigma large. Antennae long and filiform. Median segment with 

 only one transverse keel, placed on top of apical slope. Abdomen 

 smooth ; the petiole broad at the base, becoming gradually wider 

 towards the apex ; the ovipositor as long as the abdomen. Clypeus 

 clearly separated behind; its apex broadly rounded. Mandibles stout, 

 bidentate. Temples moderately broad ; the malar space moderately 

 large. Legs slender ; the claws not combed. Parapsidal furrows 

 indicated at the base. 



The eyes are bare and larger than usual ; the occiput is not 

 margined ; the scutellum is not much raised above the level of the 

 mesonotum ; the median segment is widely obliquely depressed at the 

 base ; its spiracles minute, oval ; the abdominal petiole is aciculated ; 

 the other segments are smooth and shining, and without any de- 

 pressions ; the hypopygium is moderately large. 



Belongs to the Lissonotini. It can only be confounded with 

 Lamiwonota and Asphragis ; the former may be known from it 

 by having two longitudinal keels on the median segment ; the 

 latter by its pectinated claws.

Black; the abdomen from the petiole rufous, the segments at 

 their apices narrowly lined with yellow ; the edge of the pronotum, a 

 line on the lower edge of the propleurfe on the apical half, a broader 

 line on the apical two-thirds of the mesopleuraB on the lower side and 

 the tegulfe, clear white; legs dark testaceous; thecoxfe and trochanters 

 clear white ; the hinder coxae broadly marked with black beneath ; 

 the wings hyaline, the stigma dark testaceous, the nervures black. ? . 

 Length, 6-7 mm. ; terebra, 4 mm.

Antennas black, thickly covered with a microscopic pile ; there is 

 a white mark on the apex of the scape below. Head black, and 

 covered with a white pile ; the inner eye orbits narrowly, the malar 

 space broadly, the mandibles, except the teeth, the clypeus, except for 

 an oblique black mark on the sides, a line on the sides of the lower 

 part of the face, projecting on the inner side downwards and more 

 narrowly upwards, and the palpi white. Pro- and mesothorax smooth 

 and shining ; the mesopleurse minutely punctured. Metanotum opaque, 

 shagreened, the middle closely and finely transversely striated ; the 

 apex below the transverse keel is finely, irregularly longitudinally
