 thorax. 



9. — 9.5 mm. — Head dull, finely roughened. Third joint of the antennae a 

 little shorter than the two succeeding joints combined. Pronotum bluntly den- 

 tate laterally. Dorsulum with close, rather indistinct punctures on a shining 

 surface. Pleura highly polished, th6 mesoplenra with fine, rather sparse punc- 

 tures, the metapleura partly impunctate, and partly with shallow indistinct 

 punctures. The dorsal aspect of the metathorax is dull and roughened, but has 

 a median longitudinal channel traversing it which is broader at base than at apex 

 and a little more than twice as long as wide at base and shining. The posterior 

 aspect of the metathorax has a rather irregular median longitudinal sulcus and 

 is somewhat reticulate and shining. 



The posterior margin of the anterior tibise with three rather slender spines, 

 the posterior margin of the middle tibise with seven stouter spines, the posterior 

 margin of the posterior tibise with six or seven stout spines. 



First abdominal segment polished, the succeeding segments shining, but with 

 rather a subtle sculpture. Pygidium margined laterally, closely or coarsely 

 punctured, or pitted with the sculpture of the apical half at least, obscuied or 

 almost obscured by stiff appressed golden hairs or bristles. 



The pygidium about one and a half times as long as broad at base.

 excepting the brownish apical margin, the scape, pedicellum anteriorly, the pro- 

 notum, excepting a median longituilinal black line, the tubercles, the episternum, 

 mesopleuralis, the anterior margin of the tegulse, the extreme base of the wings, 

 the scutellum and a dot on each side anteriorly, and a line on each side of the 

 middle of the postscutellum, the apical third or more of the anterior and middle 

 femora, the anterior and middle tibiae and metatarsi, the anterior aspect of the 

 posterior femora, a transverse undulating band on the first dorsal abdominal seg- 

 ment, an elongate spot on ventral abdominal segments 2, 3 and 4, an interrupted 

 band on the second and- third dorsal abdominal segments, an apical band on the 

 fourth and fifth dorsiil abdominal segments, yellow.

 the tarsi brownish. The anterior and middle tibia each with a black spot on 

 the internal aspect.
