There seems to be much uncertainty as to the correct synonymy of 

 this species. All the females before me are black, and all the males 

 are fulvous or honey-yellow; both sexes answer to the description of 

 the species which I have quoted above as synonymous with A", morio 

 Fabr., and I have little doubt that they all belong to one and the same 

 species, notwithstanding that Cruerin mentions both sexes of X. ca- 

 j mix in his description of that species, which is probably an error. 

 The females show plainly six dorsal segments to the abdomen, which i* 

 naked above, with the extreme sides of the segments and the apical 

 margin of the sixth segment fringed with black pubescence; while the 

 male abdomen shows seven dorsal segments, the last two of which are 

 densely clothed with rather long, deep yellowish-ferruginous pubescence, 

 as well as the two basal segments where the pubescence is much shorter, 

 and the seventh segment has on each side of the middle a dense tuft of 

 long fuscous pubescence. Length % 9 9 — 10 lines.
