472 MR. R. E. TURNER ON [May 12, 



The male is similar to the female, but the central lobe of the 

 clypeus is nearly as long as broad, truncate at the apex, and the 

 yellow spots on the vertex are smaller. 



Length 9 mm.

2 . Clypeus depressed on the anterior margin, widely and 

 shallowly emarginate, the central lobe twice as broad at the apex 

 as long. Antennae inserted half as far again from the eyes as 

 from each other, the distance between them and the eyes equal to 

 a little less than the length of the scape, the distance from the 

 base of the clypeus nearly equal to the length of the scape and 

 the first joint of the ilagellum combined ; the second joint of the 

 flagellum is twice as long as the first and not quite half as long 

 again as the third. The inner orbits of the eyes nearly parallel ; 

 the postei-ior ocelli about one-third further from the eyes than 

 from each other, but as far from each other as from the posterior 

 margin of the head. Clypeus and front shallowly punctured, the 

 rest of the insect, except the scutellum, postscutellum, base of 

 the median segment, and pygidium, very coai-sely and deeply 

 punctured. Pronotum very broadly and feebly rounded ante- 

 riorly, less deeply punctured than the mesonotum ; scutellum 

 transverse, shallowly punctured ; postscutellum smooth. The 

 triangular space at the base of the median segment is divided by 

 a sulcus and is deeply but rather sparsely punctured. First 

 abdominal segment about half as long again as broad, not as long 

 as the second segment ; pygidial area granulate, elongate- oval, 

 and very narrowly truncate at the apex. 



Black ; the mandibles (except at the apex), the clypeus, front 

 below the base of the antennae, scape, the carina between the 

 antennae, the pronotum broadly interrupted in the middle, the 

 tegulae, scutellum, postscutellum, the base of the second abdo- 

 minal segment broadly, the third segment (with the base broadly 

 black in the middle), the fifth segment above, and the legs (except 

 the base of the coxae) yellow ; the flagellum, the apex of the first 

 abdominal segment, the pygidium, and the posterior femora 

 ferruginous. Wings hyaline, the radial cell and the apex beyond 

 it clouded with fuscous ; nervui'es fusco-ferruginous. 



(S . As in the female, but the clypeus is longer, being as long 

 as the breadth of the central lobe at the apex and without the 

 shallow emargination, the base a little nearer to the antennae 

 than in the female. The scutellum is black ; the first abdominal 

 segment ferruginous ; the apex of the fifth and the whole of the 

 sixth yellow ; the femora and the apex of the posterior tibiae 

 ferruginous. 

 . Length, 5 7 mm., S 6 mm. 



Hah. Mackay, Queensland {Turner) ; April and May. 

 _ Allied to C. prcedcutor Sm. from Celebes, but the sculpture is 

 different, also the shape of the pygidial area.
