XYLOPHAGINiE. 



Face flat, with no socketed epistoma margined by broad side-cheeks. 

 Palpi long and remarkably upturned. Antennae with eight annulations on 

 the flagelliform third joint (figs. 180, 181), or (if Bhachicerus belongs to this 

 subfamily) with very numerous (twenty-two to thirty-two, or possibly 

 even more) separated and sometimes pectinate joints (fig. 166). Eyes of 

 the male not touching nor even approximated, though closer than in the 

 female. Tibise all spurred. 



FlQ. 179.— Xylophagiis ater S- X 6. 



Thorax almost bare, there being at most only slight soft very inconspicuous 

 pubescence with no long liairs present. 8cutellum smaller than in most Leptidce ; 

 metanotum remarkably large and conspicuous. 



Abdomen elongate, narrow, almost bare, with seven obvious segments. Genitalia 

 of the male rather complicated ; ovipositor long and telescopic. 



Legs long and thin, without any bristles or even obvious pubescence, but all the 

 tibia3 spurred : front tibite with one moderately long spur, middle and hind tibit^ 

 with two rather long almost equal spurs. 



Wings (tig. 1 79) diverging f I'om the true Leptid type ; cubital fork moderately 

 long but with the lower branch ending in or just before the wing-tip and the upper 

 branch not much more than half as long and ending in the wingmargin about half- 

 way between the ends of the lower branch and of the radial vein ; radial vein short, 

 being curved up rather quickly ; discal cell shorter than in the Leptince ; small 

 cross-vein almost absent ; alula absent ; ambient vein present though faint.
