Note. — The measurements in the males of this and 

 the two following species are exclusive of the retractile 

 abdominal segments after the 4th. The relative length 

 of the ovipositor in the females is computed from the 

 apex of the abdomen, exclusive of its subjacent and 

 more or less internally concealed basal portion. 



I have also recently received from New South Wales 

 both sexes of another remarkable species allied to 

 Blastophaga, the ovipositor, however, being as long as the 

 abdomen, and the mandibles of the female, together 

 with their serrate appendages, being furnished with 

 about thirty sharp teeth, forming one continuous saw 

 from end to end, thus constituting a most effective im- 

 plement, whose structure may favourably compare with 

 any in use at the present day ; the falcate mandible 

 representing the ordinary curvate handle, and the four 

 following teeth appertaining to the broad base of the 

 saw, the residue (twenty-six) being on the inner margin of 

 the transverse striae of the appendage. (Plate II., fig. 25). 



The antennae of the female are also peculiar. The 

 scape is distended and suboval ; the 2nd joint short and 

 as broad as long, the 3rd joint forming the usual spinose 

 projection, though short and subtrigonate ; the 4th is 

 longer than broad, but small ; the two following joints 

 are compressed and longitudinally striated, equal in 

 size, with the sides parallel, and truncate at the base 

 and apex ; the 7th and 8th are shorter and somewhat 

 cyathiform ; the last three (9th to 11th) forming an 

 elongate fusiform clava. 



The head is very large, much compressed, twice as long 

 as broad, the sides parallel and rounded at the base, 

 with a very short terminal horn. The thorax is about 

 the same length as the head ; the prothorax narrow in 

 front and subtrigonate, the apex being attached below
