than the preceding, and increasing, transverse, eleventh large ; 

 prothorax rather broad, lateral foveae distant from the margin, 

 the central one very minute ; elytra subquadrate, slightly attenuate 

 at base, trifoveate, dorsal stria nearly straight, abbreviate before the 

 apex ; first dorsal segment of the abdomen with carinulse variable in 

 length, always diverging and inclosing at the base one-fourth of 

 the width of the disk; metasternum moderately raised and depressed. 



Male : Last joint of antennae larger than the others, oblong, and 

 having underneath a strong, sulciform fovea ; intermediate tibiae 

 with an apical spur, last ventral segment broadly but obsoletely 

 impressed. 



Female : Last joint of antennae ovate. Length 1*50-1"60 mm. 



Allied to B. picticomis, Eeitt. ; in the male the antennal club is 

 very different ; it is difficult to distinguish the female from that 

 of the last-named species, but the penultimate joint of the antennae 

 is decidedly more transverse, -and the last one shorter and stouter.

Eeichenbachia picticornis, Eeitt., 

 Deutsch. Entom. Zeit., 1882, p. 188, pi. ix., fig. 6. 



Oblong, dark ferruginous, hardly pubescent, legs and antennae 

 light rufous, the latter, principally in the male, dark at tip ; head 

 subquadrate, trifoveate ; antennae of moderate size ; third to sixth 

 joints oblong, subcylindrical, seventh much shorter, nearly quadrate, 

 the others variable in each sex ; prothorax nearly as broad as long, 

 broader than the head, more attenuate in front than behind, lateral 

 foveae of moderate size, distant from the margins, the median one 

 minute and suboblong ; elytra subquadrate, slightly attenuate at 

 base and trifoveate, shoulders hardly conspicuous, dorsal stria 

 abbreviate before the apex, slightly arcuate and curving slightly 

 outward at tip ; first dorsal segment of abdomen with little con- 

 spicuous carinula, shorter than half the length of the discoidal part, 

 diverging and covering a quarter of the width ; posterior tibiae 

 slightly incurved ; metasternum rather convex. 



Male : Antennal club large, piceous, covered with a denser greyish 

 pubescence, eighth joint broader and shorter than the preceding one, 

 transverse, ninth a little broader than the eighth and more than 

 twice as long, transverse, tenth longer, subquadrate, eleventh oblong, 

 truncate at base, acuminate at tip; intermediate tibiae with an obtuse, 

 hardly discernible spur at tip, last ventral segment depressed trans- 

 versely ; metasternum abruptly impressed at apex. 



Female : Antennal club much smaller than in the male, ultimate
