produced in front of the epimera; the dise is convex and entire, but there is a transverse impression on each 
side of the base; the punctures on the front of the prothorax are simple and round, but in the middle and 
hind parts they are more oblong, closer, and more confluent, becoming short striola near the posterior angles. 
The elytra are very long and narrow ; they are shining and very delicately and irregularly punctured ; they have 
a moderately prominent costa at a short distance from the suture, the sutural stria being curved and duplicated 
beyond the middle of the elytra; on the dise are three duplicated strie, which are abbreviated behind, the 
lateral one not extending to the middle, behind which is a longitudinal impression parallel with the lateral 
margin. The two terminal spiracles are conical and prominent; the legs are rather short and strong, with the 
tibie broad, the anterior being strongly bidentate ; the podex is very convex and semicircular ; the body beneath 
is black and very glossy ; the abdomen in the only (female) specimen which I have seen not being channelled. 
The deflexed sides of the pronotum are marked with curved strie, and all the femora on the under side and the 
sides of the metasternum are similarly striated.

The small size and narrow form of this species, with an oblong prothorax somewhat swollen across the 
middle, distinguish it from the other species. It is black, slightly glossy ; the head and pronotum covered with 
minute circular punctures ; the reflexed lateral margins of the latter marked with close curved longitudinal 
striz ; and the hind margin is nearly straight, being scarcely emarginate in front of the scutellum, which is trans- 
versely striolated at the base and punctured behind. The elytra are very delicately punctured, and each is 
marked with five very fine duplicated striz; on each elytron, beyond the middle, there is a longitudinal 
impression parallel with the lateral margin. Each of the two maxillary lobes are acutely bidentate ; the men- 
tum is oblong, rounded in front, with a notch in the middle of the fore margin (fig. 6a). The anterior femora 
are longitudinally striated on the under side. The middle of the metasternum is punctured, and its sides 
marked with curved longitudinal strie placed close together. The abdomen beneath, especially at the sides, 
is finely but irregularly striolated ; the pygidium is terminated by an obtuse point, and is marked with very 
delicate circular striole. :

The mando of the maxill is acutely bidentate ; the inner edge below the teeth armed with several strong 
spinose sete. The galea is also acutely bidentate ; the mentum (fig. 8a) is oblong, rather widened in front, 
where it is obliquely truncate ; the posterior margin of the oblique truncation clothed with strong erect sete. The 
elytra are marked next the suture with,a stria formed of a fine double impressed line extending from near the 
extremity of the scutellum almost to the pygidium: a second similarly formed stria is more abbreviated both
