remaining three very small; on the inner surface of the 
mandible beginning at the second tooth is a subapical row 
of bristles. Thorax opaque, with sparse and rather large 
piliferous punctures ; pronotum nearly twice as long as the 
mesonotum, narrowed anteriorly ; mesonotum with two well- 
defined parapsidal furrows ; scutellum with a deep transverse 
groove at the base. Median segment about half as broad 
again as long, margined laterally and at the apex, finely and 
closely transversely striolate; the enclosed median space 
twice as broad at the base as at the apex, with five strong 
longitudinal carinz, the space between the carine with low 
transverse strie forming reticulations ; sides of the segment 
very finely obliquely striolate ; the surface of the posterior 
truncation subconcave, finely aciculate, with a median longi- 
tudinal carina. Abdomen smooth and shining, with a few 
scattered punctures on the third and fourth dorsal segments. 
Hind tarsal ungues (fig. 1, d) strongly bent, produced at the 
base into a strong tooth-like lobe; with one tooth which 
rises at right angles ; the apical tooth very long and acute, 
about twice as long as its basal breadth; on the external 
surface of the ungues are three bristles—one on the dorsal 
edge above the base of the median tooth, a second sub- 
ventrally on the basal projection, and a third between the 
two. Submedian cell longer than the median; radius at 
least three times as long as the basal nervure.

?. Head longer than the greatest breadth, somewhat 
narrowed behind the eyes, nearly twice as long as the breadth 
on the hind margin, finely shagreened, with a few scattered 
piliferous punctures. Eyes separated from the hind margin 
of the head by a distance scarcely exceeding one-third of their 
own length ; the posterior ocelli situated close to the hind 
margin of the head. No frontal suleus. Thorax subopaque ; 
pronotum distinctly broader posteriorly than the greatest 
length, rather strongly narrewed and rounded anteriorly, 
finely -but not very closely punctured ; parapsidal furrows 
not extending over the whole length of the mesonotum, the 
inner furrow linear, very narrow, the outer one forming a
