172 Rev. F. D. Morice on the 6th $ ventral segment 



Fig. 16. Main lobes with angles spined as in fertoni, but 

 the apical margins more convex. 



Lobes of process much shorter, and widened from base to 

 apex, so that they are nearly adjacent throughout, and the 

 gap between them is inconspicuous — much deeper than 

 wide. The pilosity is also shorter. 



I take this species to be vaulogeri, Perez, judging 

 however only from the description of that species. It 

 is a good deal like jheringi (Fig. 10), but the process is 

 certainly not identical. (Its hairs are quite otherwise 

 directed.) I have examined two specimens from Algiers. 



Fig. 17. The main lobes differ from any yet examined, 

 in that their apices lie in the centre of the segment, the 

 margins descending thence (instead of rising or running 

 transversely) towards the spined lateral angles. Conse- 

 quently they (i. e. the apices) form a pair of acute adjacent 

 angles overlapping the base of the process — an easily 

 recognizable character ! 



The process is hardly to be distinguished from that of 

 morawitzi, but its lobes are a little wider in proportion 

 to their length. And, owing to the descending outline of 

 the main lobes, it stands out more boldly at the sides. 



I think this species must be undescribed. I took it 

 ($ $ and $ ¥) a ^ Brum ana near Beirut (Syria) in 1899, and 

 propose to call it libanensis. For its external characters, 

 see the Diagnosis given below. (For its $ antenna, Fig. 30.) 



The fifth $ ventral segment is decidedly peculiar, but 

 whether its singularity has anything to do with that of 

 the 6th I cannot venture to say, though I suspect so. 



Below its actual, (centrally incised but otherwise simple,) 

 somewhat transparent margin, may be seen a sort of 

 secondary inner margin, formed by a thicker darker and 

 more solid layer of substance. This " ante-margin," if we 

 may so call it, is incised (like the true margin) in the 

 centre, and at the corners it is evidently and sharply 

 spinose — like the 6th segment. Also, laterally (near the 

 base) it emits two oblique pencils of thin long hairs, 

 which can be seen projecting on each side, even when the 

 abdomen is viewed from above. I have not noticed a 

 similar character in any other species. 



Besides the above 17 species, I took near Jerusalem in 

 1899 what is evidently yet another (probably undescribed) 

 species of the same group, with a curiously triangular 

 (almost acuminate) 7th dorsal segment, and a 6th ventral
