sulcus iviicliiug the auterior ocellus. Head and thorax 

 rather sparsely punctured ; mesoplcurie very sparsely punc- 

 tured, the sternal carina not well defined as in other species 

 of the ciliatus group ; the transverse groove at the base of 

 the scutellum loveolatc, but narrow and ill defined in the 

 middle ; ])asal area of the median segment very finely and 

 closely obliquely striated, divided by a deep longitudinal 

 sulcus, the sides of the segment coarsely punctured-rugose. 

 First abdominal segment short and not very strongly nar- 

 rowed to the base, ventral segments 4-6 with cilise of long 

 fulvous hairs, seventh dorsal segment not very small, very 

 broadly rounded at the apex. Fore tarsi distinctly ciliated, 

 intermediate tibiic with two strong epical spines, hind tibiae 

 spinose. Second abscissa of the radius very short, abouc 

 one-tenth of the length of the third ; first transverse cubital 

 nervurc sharply bent outwards near the cubitus, emitting 

 from the bend a scar which reaches to the base of the stigma ; 

 both recurrent nervures received by the second cubital cell ; 

 cubitus of hind wing interstitial with the transverse median 

 nervurc.

Type from South Australian Aluseura. 



In most points this fine species closel}^ resembles ciliatus, 

 but differs in the position of the cubitus of the hind wing, 

 which is interstitial ; in ciliatus and perhinsi, however, the 

 cubitus is much nearer to the transverse median nervure 

 than in bellicosus and other species of the group. Other 

 structural points distinguishing this species from ciliatus 

 are the lesser development of the sternal carina, the sculpture 

 of the enclosed area of the median segment, and the much 

 greater development of the second spine of the intermediate 

 tibiae. I have only seen the female of ciliatus in which both 

 of these spines are developed, but Ilandlirscli could only see 

 one well-developed spine in the male, and in several species 

 of the group the second spine is much reduced or almost 

 obsolete in the male.
