2 . Head aud thorax pubescent, abdomen densely pruiuose ; 

 the clypeus convex, subovate, the sides anteriorly roundly emar- 

 giuate", the apex in the middle truncate ; median segment with a 

 medial vertically-impressed line ending in a deep triangular hollow ; 

 petiole of abdomen suddenly widened from the middle to the apex, 

 the medial tubercles beneath large and well-developed. Black, 

 the pubescence fuscous ; two broad lines on the clypeus, an 

 abbreviated line along the inner orbits below the emargination of 

 the eyes, the scape, and basal three or four joints of the flagelluni 

 of the antennJB above, a spot between their bases, a line behind 

 the eyes, a large patch on each side of the pronotum, the femora, 

 tibi«, and tarsi of the legs, the petiole of the abdomen, except a 

 narrow subapical band above, and the apical four segments red ; 

 wings fulvous, hyaline. 



S similar ; the clypeus is shorter and narrower, the sides and 

 apex as well being deeply emarginate ; the clypeus is also wholly 

 red, the line on the inner orbits yellow ; the petiole of the abdomen 

 is more shaded with black, and the basal three ventral segments 

 have their apical margins narrowly red.

2 . Head and thorax with close shallow punctures, petiole 

 smooth, the rest of the abdomen with the surface hnely longi- 

 tudinally aciculate ; clypeus pyriform, its apex truncate ; pronotum 

 anteriorly transverse : median segment with a medial longitudinal 

 furrow ; petiole broadening towards the apex, slightly flattened. 

 Head yellow, a broad black band between the eyes on the vertex ; 

 antennfE reddish brown ; pronotum and mesonotum anteriorly 

 yellow, the latter posteriorly black ; scutellum and postscutellum 

 reddish brown ; sides of the thorax and legs black variegated with

 medial vertical black line; the sutures between the scutellum, 

 postscutellum, and median segment black; petiole and basal third 

 of the 2nd abdominal segment reddish brown, the former black at 

 base and with a subapical black band, the middle of the latter black, 

 its posterior third aud the remaining abdominal segments yellow ; 

 wings deep flavo- or fusco-hyaline. 



S similar, but slighter and generally darker ; the 5th and 6th 

 abdominal segments at base and the whole of the anal segment black.
