52 Mr. R. E. Turner on the 



$ . Head a little broader than the thorax, minutely and 

 not very closely punctured, cheeks about as long as the 

 breadth of the mandibles at their base. Antennae setaceous, 

 second joint of the flagelluin as long as the scape, a little 

 longer than the third joint ; 35 joints in the antennae in 

 both sexes. Notauli smooth at the base, distinctly crenu- 

 lated posteriorly ; dorsal surface of the median segment very 

 feebly rugulose, occupied by a very broad cordiform area. 

 Abdomen smooth and shining ; sheath of the ovipositor 

 truncate at the apex, broadened from the base, about one- 

 third of the length of the abdomen. Nervulus separated 

 from the basal nervure by a distance not exceeding one- 

 fifth of the length of the first discoidal cell on the 

 discoideus.

There is much variation in the size and intensity of the 

 black marks on the vertex and mesonotum in both sexes, 

 the female occasionally having a small spot on each side 

 close to the posterior ocelli and the male often having the 

 vertex entirely fulvous. The female has the marks on the 

 mesonotum either black or brown. This seems to be closely 

 allied to C. rufator, Roman, differing in the colour of the 

 wings, the position of the nervulus. and the number of joints 

 in the antennae. The latter character may vary. 



Cardiochiles rufator, Roman.

1 have not seen this species. 



Ihe species with cylindrical hind metatarsi would come 

 into Cameron's genus Ernestiella, which was formed for the 

 Ceylon species niffromaculata, Cam., which is closely allied 

 to the Australian species, but I cannot regard the distinc- 

 tions as of generic importance. Cameron himself some 

 years after publishing the name Ernestiella described an 

 allied Indian species as Cardiochiles fulvus. I consider that 

 Schbnlandiella, Cam., founded on a South African species, is 

 also a synonym of Cardiochiles.
