Lycomax, new subgenus 



Type of subgenus: Saropogon fiavofacialis Hull, 

 1956. 



Small flies ; the females are considerably larger than 

 males as a rule. The head is similar to Saropogon 

 Loew but the palpus is obtuse and clavate as in the 

 Brachyrrhopala Macquart complex and there are stout, 

 long, anterior dorsocentral bristles on the mesonotum. 

 The slender abdomen is cylindroid or tapered and the 

 pleuron is pollinose and without pile or bristles except 

 on the metapleuron. A microsegment is absent from 

 the end of the antenna. The scutellum bears 1 pair 

 of bristles. Length of males 11 mm., of females 16 

 mm. 



Head, lateral aspect: Face slightly concave below, 

 pollinose, and with 1 or 2 hairs, and a distinct, single 

 row of epistomal bristles. First and second antennal 

 segments with numerous, long, bristly setae or short 

 bristles. Third segment widest in the middle and wider 

 than the other segments; it has only a fused trace of 

 a microsegment. 



Head, anterior aspect: Front wider than the face, 

 convergent above; ocellarium prominent with steep 

 sides and several bristles. 



Thorax : Mesonotum relatively bare. Acrostical setae 

 are short, distinct, stout and widely separated from the 

 dorsocentral bristles, which are long, stout with 3 or 

 4 in front of the transverse suture and a like number 

 behind. Lateral bristles stout and prominent and 1 

 pair on the scutellum. Mesopleuron wholly pollinose, 

 without pile or bristles except hairs on the propleuron 

 and 2 or 3 short bristles on the metapleuron. 



Legs: The legs are as in Saropogon. Hind femur 

 without bristles, except 1 small, basolateral element; 

 anterior basitarsus with denticles. 



Wings: The wings are as in Saropogon. 



Abdomen : The abdomen is as in Saropogon and the 

 male terminalia similar to European representatives 

 of that genus. 



Genus Aczelia Carrera 



Figuees 76, 558, 1126, 1135, 1707, 1716, 1717, 18S0, 2031 



Aczelia Carrera, Papeis Avulsos Dep. Zool., Sao Paulo, vol. 12, 

 p. 297, 1955. Type of genus: Laparus argentinus Wulp, 

 1882, by original designation. 



Medium size flies with not very high, concave face. 

 The third antennal segment is without microsegment, 

 and bears a small spine at the apex. All cells of the 

 wing open, including the anal cell. Separated from 

 Dwgmites Loew by the venation and form of the an- 

 tenna and from Allopogon Schiner by the narrow face 

 and well developed pulvilli. Scutellum with a pair of 

 stout bristles. Females with acanthophorites and mod- 

 erately long spines. These are faintly pollinose flies 

 and therefore only moderately shining. From Aus- 

 tralian genera related to the Saropogon Loew group 

 they are separated by the dull surface and the multi- 

 setate legs. Length 16 to 21 mm. 



Head, lateral aspect: The face is strongly concave 

 across the middle, only moderately extended above and 

 below and resembles Austrosaropogon Hardy. Occiput
