head, thorax and propodeum, except on the scutum and scutelhim, 

 where it is unusually short and brown in color. The sixth tergite, 

 and to a less degree the fifth and fourth also, are covered with rela- 

 tively long black pubescence. The inner eye-margins are slightly 

 divergent at the clypeus. 



This species stands close to B. taiwana Bischoff from which it 

 differs in the character of its maculations, in the character of the 

 pubescence on the scutum, and in the better development of the 

 processes on sternites two and six. 



Length 22 mm. Described from a single male bearing the labels, 

 "China, Tsha-jiu-san, V.-VI. 12, Mell S. V.," and " Berggebiet i. 

 N. V. Kuangtung, Bambuswald, ca. 1400 m Hoch."

Type (male). — Black: lateral borders of labrum; narrow apical 

 band and extreme lateral borders of clypeus; short anterior orbits 

 broadened just above insertion of antennae; broad posterior orbits, 

 narrowed above and not extended to vertex ; spot on side of pothorax 

 extending to tubercle; median bilobpd spot on posterio-dorsal sur- 

 face of propodeum; lateral angles of propodeum; spot on anterior 

 part of mesosternum ; broad fascia on first tergite enclosing a round 

 black spot near anterior margin on left side of midline and having 

 a broad rounded anterior emargination on right side; broad fascia 

 on second tergite inclosing pair of elliptical dorsal spots; narrow 

 fascia on third tergite greatly shortened at the side; pair of lateral 

 spots on second sternite; femora in part; tibiae, except line above on 

 first pair and line below on second and third pairs; tarsi, except 

 apical part of terminal segment of all pairs and posterior border of 

 metatarsus of first pair ; yellow. 



The flagellum is black above but not wholly so below, and segments 

 7, 8, and 9 are slightly spinose. Segments 10, 11, and 12 are slightly 

 excavated, and 12 which is as long as 10 and 11 combined, is curved, 

 and is also narrowed toward the apex, which is roundly pointed. 

 The posterior border of the middle femur is somewhat undulate and 

 near its distal end bears two blunt rounded teeth. The second 

 sternite bears a weakly developed median process and the sixth a 

 well-developed, narrow, flattened, bluntly pointed process that ex- 

 tends slightly beyond the apex of the sternite. The seventh tergite 

 is broadly and bluntly rounded at the apex. It is slightly sinuate 

 laterally and bears a pair of lateral ridges that stand out prominently 

 when the tergite is viewed from the side.
