running from the vertical part of the aiitennal groove across the pale lateral (sensory) 

 dot towards the posterior dorsal pale dot. The two anterior biistlos of this row 

 corresponded to the anterior row of ansorijci, and the two posterior ones to the np])er 

 bristles of the second row found in that species. Above the antennal groove there 

 is one long median bristle. The snbapical row contains four bristles on each side, 

 the interspace between the lirst and second being large. 



Thorax. — The prothorax bears a row of nine long bristles on the two sides 

 together, the row of the raeso- and metathorax containing nine or ten bristles. The 

 prothoracic comb consists of fifteen to seventeen spines. The metepimerum bears 

 usually five bristles (2, 3), there being rarely an additional, small bristle present 

 in the anterior row. 



Abf/onen. — The bristles of the abdomen are a little less nnmerons than in 

 ansorqei, the postmedian row of the central tergites containing usually twelve, 

 rarely thirteen long bristles. The difference in the number of bristles is especially 

 noticeable on the modified segments viii. to x. in the t? and vii. to x. in the ?. 



yioililied Sfijments. — S. The eighth tergite bears on each side two or three 

 small bristles above the stigma. The eight sternite has a row of four or five long 

 bristles, and proximally to the row three to five smaller bristles. The dorsal outline 

 of the sensory plate (pygidinm) is almost straight, the pygidium not beins; convex 

 iu this sex. The anal tergite is very little longer than the pygidinm and bears, 

 on the two sides together, seventeen small bristles besides two longer apical 

 ones. The clasper is distally divided by a narrow rounded sinus into two short 

 rounded lobes (PI. X. fig. 12), of which the upper one (P') bears two very 

 long and three much shorter and thinner bristles. Below the lower jirocess 

 (P-) there is one long bristle at the edge of the clasper. The manubrium (M) 

 is narrowed quite gradnally to a sharp point and evenly curved, the point 

 being directed upwards. The general appearance and structure of the movable 

 finger (F) are essentially as in Gt. caacasica (and ansoryei), but the finger is 

 much broader and shorter than iu caucasica. It bears about a dozen short 

 bristles at the dorsal edge, three at the ajiex and fonr at the ventral margin. 

 The ninth sternite (ix. st.) has a rather slender vertical arm, whose apex, bow- 

 ever, is much widened, as shown in the figure. The horizontal arm is boat-shajied 



in a lateral aspect and bears many small bristles in the di.stal half. ?. The 



seventh sternite (1*1. X. fig. 13, vii. st.) is divided by a narrow sinus into a very 

 broad truncate-emarginate upper lobe and a small lower one, and bears a row of four 

 or five bristles and proximally to it three or four smaller ones. These bristles vary 

 in size, but the two below the sinus always remain large. The eighth tergite has 

 no bristles above and below the stigma, in which character the present .species 

 agrees with triodont.us and engis, while amorgei and caucasica have some small 

 bristles above the stigma. The ventral portion of the eighth tergite bears a ventral 

 row of five bristles, of which the ajiical one is stout and short and the third the 

 longest. Above this row there are three or four more bristles, the proximal ones 

 being small and the distal one large, the latter being place<l above the second of the 

 ventral row. On the inner surface there is a cluster of four or five small bristles 

 before the apex. The apical angle of this tergite is rounded ofi'. The pygidinm is 

 convex as in the ? ? of the allied sjiecies. The anal tergite is distiugnished by 

 bearing a row of three lateral bristles proximally to the stylet, the above-mentioned 

 African species as well as caucasica having only the ventral bristle of this row. 

 The stylet is conical and about thrice us long as it is broad at the base. The anal
