of the legs, antennae and wings and in the coarser 
sculpture of the median segment. There is a specimen of 
N. kurandae from Bundaberg in the same collection. 
Crahro erythrogaster, sp. nov. 
^. Mandibles bidentate at the apex ; clypens broadly rounded at 
the apex, with a delicate median carina, clothed with fine silver 
pubescence. Eyes separated at the base of the clypeus by a distance 
equal to about three-quarters of the length of the scape ; antennae 
inserted further from each other than from the eyes, 13 jointed, the 
second joint of the flagellum as long as the third and fourth com¬ 
bined ; the posterior ocelli a little further from each other than the 
eyes. Head massive, as broad as the thorax flnely punctured-rugose, 
broadly emarginate posteriorly, the eyes separated from the posterior 
margin of the head by a distance equal to half the length of the 
scape. Thorax rather more coarsely punctured-rngose, the pronotum 
very shallowly emarginate anteriorly, the margins raised, the narrow 
groove between them coarsely rugose ; mesoplenrae with a vertical 
sulcus below the anterior wing, w'ith a shallow striated groove for the 
intermediate femora ; median segment rounded at the apex, the 
dorsal surface very coarsely rugose-striate, the sides slightly concave 
and obliquely striated, the posterior truncation transversely striated. 
Abdomen oval, sessile, very closely and minutely punctured. The 
recurrent nervure is received just beyond two-thirds from the base 
of the cubital cell, the transverse cubital nervure before the middle 
of the radial cell. 
Black ; the base of the mandibles, scape, base of the flagellum 
apex of the femora, tibiae and tarsi brownish yellow ; abdomen 
ferruginous red. Wings hyaline, nervures testaceous. Length 
6 mm. 
Hah. Queensland, Bundaberg (ex coll. Perkins). 
Allied to C. doddii. Turn. The groove for the inter¬ 
mediate femora is very shallow, but the edges are raised, 
forming marginal carinae, which give the space between 
them an appearance of being depressed more than is really 
the case. The structure is similar in C. doddii.
