^ . Mandibles deeply notched on the lower margin ; 

 cljpeus flattened, truncate at the apex, t!ie apical margin 

 narrowly depressed, more broadly in the middle than at the 

 sides, a small tooth on each side of the depressed apical 

 margin. Face clothed with golden pubescence ; antennae 

 twelve-jointed, the joints gradually thickened towards the 

 apex, joints 8-11 broader than long, apical joint very large 

 and stout, blunt at the apex. Posterior ocelli twice as far 

 from each other as from the eyes. Median segment clothed 

 with fine pale golden pubescence on the sides and apex, the 

 dorsal surface with a rather broad longitudinal sulcus. 

 Abdomen fusiform, the second segment the broadest, apical 

 segment produced into a blunt point with a small spine on 

 each side. The whole insect very closely microscopically 

 punctured. Third abscissa of the radius distinctly shorter 

 than the second transverse cubital nervure, first recurrent 

 nervure received very distinctly before the apex of the first 

 cubital cell, second beyond the middle of the second cubital 

 cell. 



Hah. Brisbane {Hacker) ; November. 



Very distinct in colouring from any other species of the 

 genus; the club of the antennae is much stouter than in ■ 

 riifonigrurn and eri/throsoma, but apparently more conical 

 than in crassicorne, Ckll. 



Pison {Parapison) exclusum, sp. n. 



S . Niger, opacus ; anteunis articulis quinque basalibus, tegulia 

 . pedibusque ferrugineis ; segmeiitis dorsalibus, secuudo excepto, 



apice pallide brmieis et pallida aureo-sericeis ; alis sordide 



hyalinis, venis nigris. 

 Long. 8 mm. 



J . Clypeus feebly bilobed at the apex, covered with pale 

 golden pubescence which extends on to the front. Antennae 

 short and stout, the second joint of the flagellum a little 

 longer than the third, joints 6-11 broader than long. The 

 wliole insect closely microscopically punctured, a distinct 

 frontal longitudinal groove reaching the anterior ocellus ; 

 posterior ocelli farther from each other than from the 

 anterior ocellus and a little farther from each other than 

 from the eyes. Median segment with a distinct longitudinal 

 groove, in which lies a low carina, a transverse groove at 

 the base of the segment, the remainder of the dorsal surface 

 very finely granulate. Abdomen subsessile, short and broad ; 

 seventh dorsal segment truncate at the apex. Second 

 abscissa of the radius a little more than half as long; as
