The type of the genus is from New Guinea, but tliis appears 

 to be eoMgeneric. 



Genus UelcON, Nees. 

 IJelcon unicornis, sp. n. 



5 . Nigra ; raandibuHs basi, coxis trochanteribnsque posticis, 

 femoribusque posticis, apice nigro excepto, fcrrugineis ; teguUs, 

 palpis, segmento abdominaU prime, pedibusque aiiticis inter- 

 mediisque testaceo-ferrugineis ; tarsis posticis, articulo apicali 

 excepto, albidis ; antennis 37-articulatis, articulis 10 basalibus 

 fusco-brunneis, 11-18 albis, apicalibus nigris ; alis hyalinis, 

 venis fuscis. 



Long. 9 mm. ; terebrae long. 6 mm. 



$ . Face rugose, with a few oblique striai on eacii side ; 

 vertex and front smooth and shining; the frontal depression 

 not very deep, but strongly margined laterally, from the 

 anterior portion of the depression rises a strong blunt iiorn, 

 which rises liigher than tlie raised lateral margins of the 

 depression. Cheeks more than half as long as the eyes. 

 Thorax closely and rather finely punctured ; median lobe of 

 the mesonotum not prominent ; parapsidal furrows crenu- 

 lated ; mesopleurse smooth and shining; the mesonotum 

 behind with distinct transverse stria in the middle; basal 

 half of the scutellum occupied by a deep longitudinally 

 striated depression. Median segment transversely rugulose, 

 with four strong longitAidinal carinse on the dorsal surface, 

 the sides of the segment rugose-reticulate. First tergite 

 rather coarsely punctured-rugulose, a little more than twice 

 as long as its apical breadth; second tergite indistinctly 

 punctured-rugulose at the base, shining at the apex ; the 

 apical teigites smooth and shining. Hind femora very finely 

 serrate in the middle beneath, with a stout spine beneath 

 before the apex. The second transverse nervure in the anal 

 cell of the fore wing is only faintly indicated. First discoidal 

 cell distinctly petiolate; second abscissa of the radius less 

 than twice as long as the first, as long as the second trans- 

 verse cubital nervure, less than half as long as the cubital 

 margin of the cell ; second transverse cubital nervure oblique; 

 nervulns slightly postfurcal.

The frontal excavation is smaller than is usual in the genus, 

 and does not extend as higii as the anterior ocellus, differing 

 in this respect from the Japanese II. curnutus, Cam., in whicii 

 the excavation is very large and dee[).
