? . ClypeHS much elevated in the middle and strongly 

 porrect at tlie apex. Antennae short, the joints (except the 

 conical apical joint) broader than long- ; a very short longi- 

 tudinal carina above the base of the antennae. Posterior 

 ocelli twice as far from each other as from the eyes. Median 

 segment with a groove in which lies a carina running from 

 the base to the apex ; the pronotuni not sunk below tiie 

 mesonotum as much as in most species of the genus. First 

 abdominal segment rounded at the base. Second cubital 

 cell pointed on the radius, receiving the second recurrent 

 nervure at one-third from the apex, tirsl recurrent nervure 

 received at about the same distance from the apex of the first 

 cubital cell. 



Hah. Mackay, Queensland (^Turner). 



There are two distinct longitudinal carinse on the sides of 

 the median segment in this species, the space between them 

 is punctured, not striated as in the similar space in Serico^ 

 phorus hicoloi'.

(J. Clypeus narrowly depressed on the apical margin, 

 without lateral teeth ; apical joint of the tlagellum conical, 

 longer than broad, joints 6-10 broader than long, the an- 

 tennae twelve-jointed. Posterior ocelli about twice as far 

 from each other as from the eyes ; front with ^ very short 

 shallow sulcus. Pronotum not sunk much below the meso- 

 notum, the hind angles rather prominent. Median Segment 

 rounded at the apex, with a longitudinal sulcus in which lies 

 a carina. Hypopygium subtruncate at the apex, with a 

 minute spine. Second cubital cell pointed, receiving the 

 second recurrent nervure at about one-third from the apex, 

 first recurrent nervure received at a rather greater distance 

 from the apex of the first cubital cell.
