This fine species is similar in shape to the two preceding, the 
lateral spines of the thorax being conical, short, and nearer the 
middle than the hind angles. The elytra are rather obliquely 
truncated, with both angles slightly prominent. 
Both dorsal and ventral plates of the terminal segment 
notched. 
c? Ovipositor projecting to the length of nearly two lines 
from the tips of the elytra. 
Ega, closely adhering to slender branches of dead trees. 
Genus Hylettus, nov. gen. 
Body elongate-oblong, more or less depressed, free from setse. 
Head, as in all the allied genera, much narrower than the thorax, 
with the antennse approximated at the base; muzzle short and 
obtuse; lower lobe of the eyes subquadrate. Antennse greatly 
elongated, sparingly furnished beneath with short bristles. 
Thorax uneven on the surface ; lateral tubercles prominent and 
placed near the middle of the sides. Elytra without smooth 
lateral keels proceeding from the shoulders. Sterna simple. 
Terminal abdominal segment in the males with both dorsal and 
ventral plates notched or emarginated. Ovipositor of the female 
elongated, tubular ; dorsal plate pointed, ventral truncated. 
Legs moderate ; thighs clavate, thickly so in the males ; basal 
joint of the posterior tarsi as long as, or longer than, the two
