PART 1 



Abdomen: The abdomen is comparatively elongate, 

 yellow with black bands and clavate from the end of 

 the rather long second segment. The surface is scant- 

 ily covered with fine, suberect setae. Sides of first 

 segment with 5 stout, spinous bristles. Males with 

 seven tergites, the eighth well concealed. Male termi- 

 nalia largely tucked under the seventh tergite where 

 it cannot be inspected. The proctiger is conical, quite 

 large and undivided dorsally. 



Distribution : Australian : Neosaropogon claripennis 

 Eicardo (1912) ; harlequina, new species; minor Hardy 

 (1934); nigrinus Eicardo (1918); princeps Macquart 

 (1848) [ = canus "Walker (1849), numicius "Walker 

 (1849), allia "Walker (1849) ]. 



Lycotherates, new subgenus 



Type of genus : Lycotherates harlequina, new species. 



Flies related to Neosaropogon Ricardo, but with 

 long, tapered abdomen, longer than the wings in con- 

 trast to the shorter, clavate abdomen of Neosaropogon. 

 The antenna bears a comparatively long, distinct micro- 

 segment; in Neosaropogon it is very short or more or 

 less fused and cup-shaped. 



Lycotherates harlequina, new species 



Large flies with elongate, slender abdomen, some- 

 what tapered; abdomen as long or longer than the 

 wings and characterized by the general, light reddish 

 brown coloration, dense, golden micropubescence of the 

 face, the sharply delimited, basal, black bands and 

 narrow, posterior, black bands on the abdominal ter- 

 gites. Length 25 mm. 



Female : Head : The head is black but densely over- 

 laid with brownish, golden micropubescence on the 

 occiput, front and vertex and with bright, golden 

 micropubescence over the whole face. Ground color of 

 face reddish brown. Palpus brownish yellow, attenu- 

 ate, with the apex darker. Proboscis similarly colored, 

 but more brownish on the outer half and narrowly 

 black along the upper border. All bristles and pile 

 of the head reddish yellow, except the mystax, which 

 is composed of 1 row of 8 pairs of long, yellowish white 

 bristles. Antenna pale orange with the third segment 

 becoming smoky brown or blackish on the apical 

 fourth. The microsegment is 2 or 3 times as long as 

 wide, blackish, truncate at apex, with a bristly spine 

 at the tip. 



Thorax: The thorax is reddish brown with black 

 markings restricted to the mesonotum where they form 

 a broad, medial stripe reaching from the anterior mar- 

 gin a short distance past the suture and there is sub- 

 medially an equally wide, black stripe, which begins 

 well behind the humerus and ends a short distance from 

 the scutellum and posterior callosity. Extreme lower 

 border of scutellum darker in color. The middle of the 

 metanotum is widely black. 



Legs: The legs with the hind pair considerably 

 lengthened, the color everywhere light reddish or 

 orange brown, except that the apical fourth of the hind 



femur and the apical third of the hind tibia are black. 

 All pile reddish golden, the bristles of the same color, 

 all bristles quite stout but unusually short. Laterally 

 on the hind femur are 14 such bristles and ventrally 

 7. Hind tibia with 8 dorsomedial, 9 dorsolateral, and 

 6 ventrolateral bristles. 



"Wings : The wings distinctly tinged with brown and 

 rather uniformly covered with reddish brown villi. 

 The anterior half of the subcostal cell is especially 

 dark, due to the dense villi. 



Abdomen : The abdomen is light brownish or reddish 

 orange. Basal margin of first tergite blackish along the 

 middle only. Just before the middle of the second ter- 

 gite is a prominent, transverse, black band not quite 

 reaching the margin laterally. Base of third tergite 

 with a broader, black band more closely approaching 

 the lateral margin. Base of fourth and fifth tergites 

 likewise with broad, black bands, which reach the mar- 

 gin. Sixth tergite with a much narrower, basal, black 

 band. Fourth and fifth tergites with a narrow, poste- 

 rior, black border, which largely results from the over- 

 lapped portions of the following tergites shining 

 through. All these black bands of the abdomen are 

 rather sharply delimited. Acanthophorites with 5 pairs 

 of stout, long, reddish spines. Pile of the abdomen 

 scanty, fine and setate, becoming a little more abundant 

 and longer on the last two tergites. Sides of first tergite 

 with 4 short, red bristles. 



Type: Female, 37 miles southeast of Perth, "West 

 Australia, January 6, 1954. Collected by F. M. Hull ; 

 type in author's collection, paratype from "West Aus- 

 tralia in the Commonwealth Scientific and Industrial 

 Eesearch Organization collection in Canberra, Aus- 

 tralia. 



Genus Neocyrtopogon Ricardo 



Figures 104, 550, 1093, 1102, 1706, 1790, 1791, 1912 



Neocyrtopogon Ricardo, Ann. Mag. Nat. Hist., ser. 8, vol. 9, p. 

 589, 1912. Type of genus : Neocyrtopogon bifasciatus 

 Ricardo, 1912, by monotypy. 



Large, pale colored flies with rather long legs and 

 elongate, subclavate abdomen. They are related to 

 Neosaropogon Eicardo but the antenna is longer, espe- 

 cially the third segment and the proboscis is distinctly 

 short, directed forward but not extending beyond the 

 middle face and barely beyond the epistoma; an im- 

 portant difference lies in the character of the face 

 itself which is rather strongly produced in the middle 

 but uniformly rounded and convex from above and 

 below and from each side, without pile and with bris- 

 tles confined to a single row of 3 or 4 short, stout, 

 pale elements above the epistoma. Palpus and pro- 

 tibial and basitarsal structures characteristic and the 

 same as in Neosaropogon. Scutellum without bristles; 

 presternum dissociated. Female with acanthophorites 

 and spines. Length 16 to 24 mm. 



Head, lateral aspect: The head is slightly higher 

 than long; the eye is a little wider below the middle
