730 MR. R. E. TURNER OX 



5 . Wings short, the length of the costa of the fore wing not 

 exceeding two and a half times the breadth of the mesonotum. 

 Radial cell broad, the apex detached from the costa and narrowly- 

 rounded. Third abscissa of the radius nearly half as long again 

 as the second, and more than twice as long as the first ; second 

 transverse cubital nerviare received at about two-fifths from the 

 base of the radial cell. Second cubital cell not very strongly 

 pi'oduced towards the base on the cubitus, receiving the first 

 recurrent nei'vure near the middle, second recurrent nervure 

 received just beyond one-quai'ter from the base of the third 

 cubital cell. Basal joint of hind tarsi finely pectinate beneath ; 

 basal joint of fore tarsi with six spines abo7e and about eight 

 shorter ones beneath; basal lobe of tarsal ungues bluntly rounded. 

 Sparsely punctured, more closely on the front, pronotum, and 

 abdomen ; the apical abdominal segments more strongly punctured 

 than the three basal segments. 



Rufo-testaceous ; head, mesothorax, and three apical abdominal 

 segments black ; mandibles at the base and scape fusco-ferruginous; 

 pubescence rufo-testaceous. Wings hyaline, tinged with yellow ; 

 nervures testaceous, the stigma black. 



Length 17 mm. 



Hah. Champion Bay, W. Australia. 



The process beneath the hind femoi^a near the apex is much less 

 developed in this species than in most Australian species, though 

 the femora are by no means convex beneath as in most of the 

 South- American species and in A. nubilipennis. 



4. Anthobosca flavicornis Sauss. 



Cosila [Callosila) flavicornis Sauss. in Grandidier, Hist. Mada- 

 gascar, XX. p. 233 (1892), $ . 



5 . Radial cell with a slight angle at the apex ; second abscissa 

 of the radius shorter than the first, the third longer than the 

 first and second combined, third cubital cell of about equal 

 length on the radial and cubital nervures. Second cubital cell 

 much produced towards the base on the cubitus ; first recurrent 

 nervure received about the middle of the second cubital cell, 

 second just before the middle of the third cubital cell. Basal 

 joint of hind tarsi Avith a scopa beneath, in which are a few 

 spines longer than the hairs ; basal joint of fore tarsi with six 

 stout spines above and a row of very fine spines beneath ; basal 

 lobe of tarsal ungues rounded. The lobe beneath the apical 

 portion of the hind femoiu has the lower margin nearly straight, 

 only very slightly rounded, and is strongly developed. Shining 

 and rather sparsely punctured, the anterior half of the pronotum 

 and the median segment closely and finely punctured and sub- 

 opaque. 



Black, with white pubescence ; the flagellum orange ; calcaria 

 white, the spines of the tibife and tarsi reddish brown. Wings 

 fusco-hyaline, nervures fuscous.
