 rated, cylindrical, straight, incurved at tip, finely pointed, briefly

60. Labia brunnea. Head rather dark castaneous, smooth, 

 slightly tumid, with two faint, broad, short, shallow, nearly longitudi- 

 nal impressions between the antennas ; mouth parts luteo-castaneous. 

 Antennae 11-jointed, luteo-castaneous. Pronotum nearly as broad as 

 the head, scarcely broader posteriorly than anteriorly, of equal length 

 and breadth, quadrate, the posterior angles rounded, and the hind 

 border otherwise straight, slightly tumid anteriorly, with a slight 

 median impressed line, which posteriorly is supplanted by a pair of 

 closely approximated similar lines, rather dark castaneous, broadly 

 bordered on the sides and hind margin with luteous, which is sepa- 

 rated from the castaneous by a blackish fuscous belt. Tegmina 

 castaneo-fuscous, darkest next the base, fully half as long again as 

 the pronotum, squarely docked at the tip; wings rudimentary, use- 

 less. Legs castaneo-luteous, the femora slightly infuscated. Abdo- 

 men dark castaneous, the posterior borders of the segments marked 

 with blackish, the sides of the abdomen somewhat convex, the lateral 

 plications of second and third segments rather slight, the surface very 

 finely and faintly punctulate. Pygidium of male very coarse and 

 etout, bluntly conical and truncate. Forceps of male more than half 

 as long as the abdomen, simple, trigono-cylindrical, a little depressed, 

 rather stout, horizontal, gently incurved, with a basal and preapical 

 slight triangular depressed pointed tooth on the inner edge; the 

 apex bluntly pointed, depressed. Forceps of female (pupa) about 

 one-third as long as the abdomen, simple, straight on the middle 

 half, but as a whole slightly sinuate, horizontal, depressed, but 

 broadly ridged above, the inner edge delicately toothed, fading out 

 toward tip. Length of body, 6.5 mm. ; of antennae, 2.8 mm. ; of 

 tegmina, 1.5 mm.; of hind femora, 1.5 mm. ; of forceps, d", 2.25 mm.,
